Title: Electronic aircraft proximity warning system - has single frequency alternating cycle transceiver with altitude comparator rejecting signals from aircraft outside specified height range
Inventor: GRUENTHAL KLAUS
IPC: G01S13/933
Filed: 1976-11-18
Abstract: The electronic air-to-air aircraft proximity warning equipment has a single frequency transmitter-receiver operating in a frequency range not normally used for aircraft. Using a multi-vibrator, it is made to transmit, and receive alternately in 1/2-second cycles. The signal transmitted may be modulated by three recognition notes. The effective range is up to 6 nautical miles, all round, the warning given being visual and audible. An altitude comparator rejects signals originating more than 150 m above or below the aircraft, and visually indicates relative altitude of notified aircraft.
Patent DE-2653843-A1 (DE)
Inventor: HAMMER OSKAR DIPL PHYS
IPC: B61K7/12
Filed: 1976-11-26
Abstract: In a shunting system with controllable eddy current track brakes (1, 2, 3) the brakes are briefly completely excited before each braking process so that the brake bars (4, 5) applied to the brake move into the operative position. As a result, even in the case of a possibly very low excitation of the brake during the actual braking process a defined braking effect is achieved by eddy current braking and mechanical braking. <IMAGE>

Title: Vacuum sealing an envelope of flexible synthetic material - in turret machine injecting steam before electrodes weld inlet
Inventor: RUEFF HERBER T RICHARD
IPC: B65B43/46
Filed: 1976-11-27
Abstract: A vacuum is set up in a bag formed from a film of heat weldable material. The opposite ends at the opening of the bag are brought towards each other so that the mouth is opened. A steam feed nozzle is introduced into the bag and the ends of the month mouth are pulled apart so that its edges close over the nozzle. Steam is fed into the bag, the nozzle is withdrawn whilst the ends are still stretched, and the edges are welded to seal the mouth of the gas. Whilst the steam is being injected, radiant heaters maintain the temp. at the mouth of the bag above that at which steam condenses and below the point of which the material of the bag becomes plastic. The method is simple, quick, efficient and ensures that foodstuffs can be stored safely.

Title: IC engine emission reduction system - uses rich mixt. and air to afterburner at idling and full load and lean mixt. at part load
Inventor: BRANDSTETTER WALTER DIPL ING D
IPC: F01N3/22
Filed: 1977-06-28
Abstract: The process is intended for operating an Otto engine comprising a carburettor (1) and an after-burner (5) to reduce the amount of harmful components in the exhaust gas. There are systems (6-8) to introduce secondary air in the exhaust line (4) upstream of the after-burner. The carburettor produces a rich fuel mixture during start-up, idling and at full load whilst sufficient secondary air is supplied to achieve complete combustion in the after-burner. Under all other operating conditions the carburettor supplies a lean mixture whilst the secondary air supply is shut-off. The secondary air supply line (7) may contain a valve (8) which is only opened during start-up, idling or full-load operation.

Patent DE-2758587-A1 (DE)
Inventor: LORINI ROMANO DIPL ING
IPC: F16H59/38
Filed: 1977-12-29
Abstract: The vehicle transmission has a two-speed transmission and a multi- speed transmission coupled in tandem. A preselector device (30) determines the direction of movement of the shifting clutch of the two-speed transmission. Two solenoid valves (17, 19, 21; 18, 20, 22) control the pressure medium supply to the actuating cylinder of the shifting clutch. Circuit breakers, actuatable by the manual shift lever (3) of the multi-speed transmission and provided for locking the gear change of the two-speed transmission are inoperative in the non-rotational position of the pair of gears of the multi-speed transmission, that is in the neutral position of the manual shift lever (3) shown. The two-speed transmission can then be shifted. A centrifugal switch (40), driven at the speed of the input shaft (87) controls further circuit breakers (39, 39') and holds one in the closed state and the other in the open state respectively so that when the drive clutch is operated at high speed the two-speed transmission (87 to 91) is shifted to the stage with the larger transmission ratio and when operated at low speed to the stage with the smaller transmission ratio. This makes operation easier and reduces the synchronising work and the wear. <IMAGE>

Title: Rolled product cooling bed - with forced air circulation around walking beam conveyor
Inventor: KNAAK RUEDIGER DIPL ING DR
IPC: B21B43/00
Filed: 1978-03-15
Abstract: Cooling beds of the walking beam type for slabs, blooms and billets are totally enclosed and are equipped with ventilators which circulate the air from the underside to the top in a clockwise or anticlockwise circle. Additional nozzles or ventilators are arranged in the underside section to overcome the resistance, caused by the beams. The billets are conveyed along the cooling bed at right angles to their length by a conveyor with fixed and walking beams. Ventilators ensure an anticlockwise air circulation. The result is a much more uniform cooling effect by preventing short circuits between underside and top of the circuit.
