" GERMAN INVENTORS - RENEW AGTIVITIES _ Patents Range From New; Anesthetics and Dyestuffs to Modern Pig Sty. » __The German chemist once more is €oming to the front. Distorted into a sinister figure dur- ing the war and his patents seized by | the allied nations, he has renewed his ! researches into the structure of matter | and a flood of patentable formulas for synthetic dyes and medicines is coming forth from his laboratories. Among the 3,176 patents issued in Washington last week German inventors have a prominent place with formulas - Tenging from a new anaesthetic to new T dve stuffs. The anesthetic, described as an animo-benzoic acid product, diethyl animoethanal, was patented by . Walter Schoeller and Hans Georg * Allardt of Berlin, Other chemical : patents issued, besides those for dye- L stuffs were for a process of introuuciig : sulphoanic groups into organic com- pounds and for gasifying and distilling solid fuel. Still another was for an acid-resisting wrapping material. But not all the German inventors are eoncerned with organic chemistry, where they have won their greatest triumphs. ~ William Lodige of Pader- born received a patent for a pig-sty, with a dining room and bed chambers . for the hogs in addition to space for t the less aesthetic activities which are . most conspicuous in ordinary pigpens. T It apparently is intended to enable % young pigs to be reared for the slaughter ‘" in a more refined atmosphere, with . “separate compartments for rearing, ! with sleeping and feeding rooms.” : Invention Aids Campers Erich Fabrianke of Berlin is con- cerned with improving the lot of camp- ers with a means of lighting tents with + electricity. This consists of a dry bat- tery arrangement incorporated in the . center pole of the tent. Thus the elec- tric light plant becomes part of the . tent itself and the camper need never T be without this adjunct of civilization 1 wherever he stops for the night. Inventions for the week covered a ‘wide range, from new types of television apparatus and a means of telephony over power lines to eyelashes for dolls which can be bent naturally so as to give the doll a more lifelike appear- ance, and an egg opener patented by a - Californian designed as a valuable ad- dition to the housewife's kitchen kit. © The latter consists of a pistol-like ar- ° rangement operated with a trigger, the egg being contained in a receptacie at . the end and the shell cut away with knives. 5 Another curious patent was for “water skates"—"elongated, waterproof tanks pointed in front and square be- hind,” which can be fastened on the foot and with which presumably the person with = appropriate skill can “skate” over the surface. Flying Device Patented. ‘The old dream of the ‘“bird-man” goaring through the air with his own wing apparently is not satisfied with the airplane, the dirigible or the glider, and inventors constantly are trying to get back closer to the model of Icarus. Such a device was patented this week by Emile Laurent of Paris, “a flying apparatus comprising in combination a 1 cuirass to be fixed on the body to cover ! the back and the head, a propeller, two : movable lateral planes of angle, the in- ‘clination of which may be altered at ‘will, means for operating by hand said Jateral planes, two lateral, stationary, < supporting planes, two supporting tur- bines with eccentric extensible blades, and a motor with oval base arranged on said cuirass and driving turbines and propeller.” It seems to be something like an air- Pplane without a fuselage, or rather with . the body of the aviator to which the - wings are attached forming the fuselage. A man lugs his motor through the air 1 on his back and flies with it. CAR OF MANY FAILINGS CAUSES OWNER’S ARREST : Defective Lights, Brakes, Horn and | Steering Gear Found by In- specting Officers. ‘When Wannsell Lovell, 35, drove his automobile out from the curb along New Jersey avenue last night, the po- lice reported both headlights were de- funct, the brakes were but a shadow, the steering fear was undetermined and the horn was only a whisper of what it should have been. An interested spectator to Lovell's “take-off,” Officer Q. E. Heyney of No. 2 precinct halted the motorist when he had driven but a few yards. Curious of Lovell's intentions and doubtful of the vehicle's ability, Heyney conducted & minute inspection of the machine n:;i returned a verdict of “not driv- able.” “Driving & machine in an unsafe mechanical condition” was the charge preferred at No. 2 precinct, where Lov- ell was taken. He was released on col- lateral. The journey to the station house was made on foot. ‘““STANDARD”’ Plumbing Fixtures ON EASY -PAYMENT TERMS No Monthly Payments Till October . . .

Zoo Road Unsettled. That section of the parkway lying | between the Natlonal Zoological Park and Massachusetts avenue has now been mmrletedA While the question of by- passing the Zoo has not been finally settled, Col. Clarence O. Sherrill, for- mer director of Public Buildings and Public Parks, approved a plan under which the roadway would continue on the east side of Rock Creek, keeping away from that section of the Zoo con- taining the animals, but the matter is being given further study. It has been proposed that the road, completed to a point north of Calvert street, the ford, be carried across the creek at that point, or constructed an easy curve to the base of the rocl Cliff. Under this program, engineer: Creek and Potomac | rovide additional facilities | THE SUNDAY STAR, WASHINGTON, said, it would mean that the clift would not be disturbed, but that a rip-rap wall would be constructed out into the stream, so as to force the bed of the creek to the westward and permit a road to skirt the base of the cliff and be continued on the east side of the creek. Under tentative plans worked out by the engineers, it is provided that the road in the Rock Creek and Potomac Parkway would be 40 feet wide, with| room for expansion to 50 or 60 fee being allowed. This would mean a 40- foot roadway all the way from thc Potomac River up to the National Zoo- | logical Park. The idea of a through traffic high- way from the Potomac River up to the District: line would not be feasible, it was explained, as the roads in Rock Creek proper were not constructed for heavy traffic and are narrow and wind- ing, in parts. This situation may be remedied later under another program. A progoux has been under consid- eration by the National Capital Park and Planning Commission by which | the Smithsonian Institution which is in charge of the National Zoological Park, would permit an exchange of land in Piney Branch Valley, utilizing that section for some of the animals so that a through road could be con- structed through the grounds of the National Zoological Park. The question of the Chesapeake & Ohio Canal, into which Rock Creek flows, running from Pennsylvania ave lem to be surmounted in the construc- tion of the completed parkway. This property has been in litigation for some time and is being handled by Depart- ment of Justice officials. During the coming fiscal year, begin- ning July 1, if sufficient funds are available, it is proposed to work on that section of the parkway lying be- tween Massachusetts avenue and the | Q Street Bridge. A tunnel under Massa- chusetts avenue is proposed at a cost of some $400,000, but it has also been suggested that a bridge, comparable tc the beautiful structure erected where Connecticut avenue crosses Rock Creek, be constructed. This bridge would bc bullt at a cost estimated at $1,200,000. If the District of Columbia appro- priation bill is passed, it would provide $135,000 to be used toward the develop- ment of this parkway. Tentative plans of Lieut. Col. U. S. Grant, 3d, provide that $20,000 of this would be spent on completing the sea wall in the vicinity of New Hampshire avenue. The bal- ance of $115,000 would be spent on sub- grading_roads in that section of the Rock Creek and Potomac Parkway lying between Masachusetts avenue and | Q street, which is known officially as ‘Section 3." | part of the main road in the area be- | tween P street and Pennsyl a ave- nue, known as “Section 2,” would be | subgraded. Considerable excavation work will be necessary in the area of the Rock Creek kK a B, nue south to the river, is another prob- | struction, near the Lincoln Memorial. With this money, also, a | D." O ROCK CREEK AND POTOMAC PARKWAY and Potomac Parkway iying between @ street and Pennsylvania avenue, as the valley narrows down at that point. ‘Two or three brid are contemplated at various points . Massachusetts ave- program proposes & new bridge to replace the present P street wooden structure, In the construction of the long- closed M Street !fldg.!c rovision has been made for the Creek and Potomac Parkway to pass beneath, at the side of the creek, where it the Chesapeake & Potomac Canal. 'The valley roadway will then be thrown across the creek at & point to the southward of Pennsylvania avenue, to permit the road to link up with the Potomac Park road system, by way of the Rock Creek and Potomac Parkwa approach, which is now under con The Rock Creek and Potomac Parl way was authorized in 1913. First ap. propriations for the project were made in 1916, when money became author- ized for the acquiring of land in that section. Now, practically all of the land has been acquired, so as to insure completion of the low level roads be- tween the Zoological Park and Potomac Park, as rapidly as funds for this pur- pose become available. The completed Rock Creek and Po- || tomac Parkway will provide an impor tant traffic artery to the northward, an important feature of this being that it will be entirely free of grade crossings, for the greater part. The National Capital Park and Planning Commission has under consideration the projected construction of three or four “high! level” bridges to obviate grade cross- ings at points such as Tilden street. It is expected that a determined ef- fort will be made this Winter to induce Congress to authorize funds sufficient || for the immediate completion of the | parkway project, in view of the 1932 fete DOES YOUR FAMILY HAVE A CAR?
