Title: Ventilated lighting strip with independent air intakes - has open hollow slitted carrier rails closable or connectable to intakes
Inventor: POELLMANN JOHANNES
IPC: F24F13/078
Filed: 1973-08-09
Abstract: The strip of lights, with lateral ventilating air intake, is fixed on carrier rails which are a hollow shaped section, open downwards, with intake slits on the side facing the ceiling. The slits can, as required, be closed by a shutter or connected to one or more air intake sockets. Carrier fittings for the lights are pref. mounted on one longitudinal side of the hollow section, which may have a further fitting on the other side for the attachment of ceiling elements. Air intake connections can be distributed over the whole length of the lighting strip, independently of the spatial arrangement of individual lights, and attachment of lights and ceiling elements is simplified.

Title: Aluminium-copper-magnesium powder mixture - for sintered products having superior strength
Inventor: STORCHHEIM SAMUEL
IPC: C22C1/04
Filed: 1973-12-29
Abstract: The mixt., which is free of incorporated organic lubricating agent, and is obtained by intimately mixing the metal powder components comprises essentially Al powder, 2-4 wt. % non-scaly copper flock of which the surface is covered with 0.03-0.05 wt. % scaly type lubricating agent, e.g. stearic acid, and 0.2-2 wt. % Mg powder. The powder components are mixed together for a period of at least 30 min. pref. at least 1.5 hr. after which the mixt. is compacted and sintered in known manner. The mechanical properties of the sintered product depend on the time of mixing the powder components. The tensile strength and bend rupture strength increase with mixing time to a max. and elongation increases in a similar manner.

Title: Calendar with lever alteration of date and day - having two interchanging card stacks and month and day discs
Inventor: SCHARRER HANS WILHELM
IPC: G09D3/04
Filed: 1974-03-13
Abstract: The perpetual calendar is designed to permit manufacture, with the exception of springs, completely from plastic. In the ousing two stacks of data coards are arranged, one comprising 16, the other 15 cards. Two levers at the front and back of both stacks are joined together to form a handle which can be pulled downwards. This works in conjunction with a spring, so th at, when the handle is pulled, one card is carried downwards by a slide until it covers the lower stack. Release of the handle causes the spring to actuate another side to carry a card from the lower stack upwards under the upper stack.

Inventor: GRUSZECKI WOJCIECH
IPC: C07C67/00
Filed: 1974-04-18
Abstract: Aminoacids, e.g. peptides, 7-amino-cephalosporamic acid, 6-aminopenicillamic acid and their derivs. contg. an acid group. are acylated by acid chlorides or mixed anhydrides of the alkoxycarboxylic acid, in which the amino-acids are in the form of salts soluble in lower alcohols, especially methanol, e.g. t-amine or metallic salts, and the reaction is performed at -10 to -70 degrees C. The reaction is readily controlled as the salts are soluble. The low reaction temp. gives a low incidence of by-products.

Title: Optical cable resistant to tension, torsion, shock and shear - cushioned against rucking, compression and abrasion
Inventor: OESTREICH ULRICH DIPL ING
IPC: G02B6/44
Filed: 1975-03-25
Abstract: An optical cable consists of a robust core of synthetic material having great tensile strength, surrounded by the optical transmitting elements. Each of these is loosely enclosed in a protective, mechanically resistant synthetic sheath, composed of two layers, the materials of which have different mechanical properties. Together they form a sheath fully capable of standing up to the physical demands made upon it, and the inner layer has moreover a lower coefficient of friction as against the optical transmitting element. The optical elements in their sheaths are enclosed in a multi-layered wrapping formed by a highly mechanically resistant band, on which a cushioning layer of synthetic foam is arranged; the whole being enveloped in an outher covering of polyurethane. Withstands the roughest mechanical handling and contains no metal likely to set up electromagnetic disturbance.

Title: Dry sump IC engine for vehicles - has oil reservoir in upper part of crankcase
Inventor: LAMM HEINZ
IPC: F01M1/02
Filed: 1975-05-31
Abstract: The engine has an oil reservoir (2) formed as an integral part of the upper half of the crankcase casting (3) inside the crankcase.

Title: Vertical deflection circuit for TV receiver - has bias voltage which is used to control DC feedback level from pushpull output stage
Inventor: POLLAK ALFRED
IPC: H03K4/72
Filed: 1975-06-18
Abstract: The vertical deflection circuit, for a television receiver, has the required bias voltage generated in such a way that it has no detrimental effect on the negative feedback between the output transistors' connection point and the base of the drive transistor. The output stage consists of two complementary pushpull transistors with a dc current-feedback network between their common output point and the input of the drive transistor coupled to their bases. The bias voltage is applied to the feedback network to alter the dc level. The bias voltage (b) is obtained by rectifying (16, 17) the ac output voltage (a) of the output stage (1, 2).

Title: Forming openings in resilient thin-walled plastic pipes - by cooling pipe before making openings by punching or cutting (NL080976)
Inventor: PUTTER WARNER JAN DE
IPC: B26F1/00
Filed: 1975-07-10
Abstract: Openings are formed in plastic pipes, esp. thin walled ribbed pipes, e.g. pipes for drainage or irrigation purposes in agriculture, made of plastic having a low modulus of elasticity, esp. polyolefins, e.g. polyethylene or polyproylene, by subjecting the pipe to the direct or indirect action of a cooling medium, before forming the openings by punching or cutting. Enables the openings to be made rapidly and accurately, as the resilience of the pipe is decreased. Pipes with very thin walls can be processed. The pipe is cooled by spraying a liquid medium, esp. water at 0-5 degrees C, onto the tube, and then treating with cooled air.

Title: Slot assembly for coins inserted into telephone - has spring-loaded rotatable slotted disc on slotted plate fixed to coin box
Inventor: RUZIC HUGO ING GRAD
IPC: G07F1/02
Filed: 1975-08-27
Abstract: The slot assembly, for coins inserted into a coin-operated telephone, consists of a plate (1) fixed to the coin box and a rotating disc (2) on the fixed plate. The rotating disc is spring-loaded and is rotated against the action of this spring until its slot (3) coincides with the slot (4) in the fixed plate. The spring may be replaced by a magnet. Parts of the sides of the slot in the rotating disc are sloping (6). The parts of sides that are sloped are those that form trailing edges when the disc returns to its original position after the coin has been inserted so that the slope helps push the coin through the slot in the fixed plate.
Patent DE-2540935-A1 (DE)
Title: Remote controlled gear with axially sliding spur gears - has brakes to reduce relative rotational speed between gears
Inventor: BETZING RUDOLF
IPC: F16H61/02
Filed: 1975-09-13
Abstract: A transmission gear for remote control has a brake (20) to prevent the gear wheel (1) on the output shaft from rotating. A second friction brake (40) on the input shaft is used to slow down the drive shaft and the gear wheels (25, 26) on it. To change gear, the gear wheels (23, 24) on the output shaft are movex axially so that the second pair of spur gears mesh. This change over of gear wheels is made easy due to the slow relative angular speed between the two gear wheels concerned. When sufficient gear mesh is obtained, sensors produce a signal which will release the two brakes.
