Title: Car interior heating system - has dashboard outlet port union downstream of others in distribution chamber
Inventor: FOERSTER MICHAEL DIPL ING
IPC: B60H1/00
Filed: 1990-01-16
Abstract: The heating and/or air-conditioning is for motor vehicles, particularly cars, and has an air inlet union to a housing containing a heater. This is followed by a distribution chamber, with unions controlled by shutters to discharge ports aimed at the windscreen and footwell, and one in the dashboard. One at least of the unions (17', 17") to the dashboard ports in the distribution chamber (14', 14") is downstream of the other ports (15', 15") in the direction of air flow. One or more fresh air passages (21', 21") controlled by a shutter (23', 23") bypass the heater (13), and lead to a nozzle (22', 22") near the unions (17', 17") for the dashboard ports. USE/ADVANTAGE - Better control of heated air supply.

Title: Fine coke addn. to contaminated earth before washing - aids sepn. of heavy metals and hydrocarbon(s)
Inventor: GRALHER MANFRED
IPC: C02F1/28
Filed: 1990-02-13
Abstract: Soil contaminated by heavy metals and/or hydrocarbons, esp. petroleum and derivatives, is treated with an aq. washing medium. During or before the washing, a fine-grained carbonaceous material, esp. coke, is added to the soil, and adsorbs much of the contaminant. After washing, the carbonaceous material is classified into coarse and fine fractions. The coarse fraction containsa only a min. amt. of contaminant, but the fine fraction with the higher content is mechanically or physically treated, e.g. by flotation to recover contaminant. In one treatment, the filter cakes from classification are burned, leaving heavy metals in the low-bulk ash. Sepd. filtrate may be returned to the washing process. ADVANTAGE - Effective purificn. involves low energy and water consumption.

Patent DE-4019077-A1 (DE)
Inventor: DENI FRANZ
IPC: B60D1/14
Filed: 1990-06-15
Abstract: In the case of a rotary swather the machine is connected to a carrying frame (3) so as to be capable of swivelling about a vertical axis (12) and a horizontal axis (9). In addition the machine in the retracted transport position is supported by a telescopic linkage (17, 18) against the carrying frame (3). In order to prevent lifting of the wheels when descending an incline or when pushing backwards and to suppress lateral drifting of the machine when running across an incline, preloaded helical compression springs (29) are built into the telescopic linkage (17, 18), which springs keep the machine in its normal position or return it to this.   So that no undamped vibrations can occur when turning and reversing the machine, friction brakes are incorporated into the telescopic linkage (17, 18) in the form of spring-loaded bushings (27), which brake in one direction but in the other direction have almost no braking effect. <IMAGE>

Title: Equalising potentials of tanks without sparking - using variable resistance in series with conductor joining tanks, resistance being reduced from very high to zero
Inventor: GAEDKE HERBERT DIPL ING
IPC: H05F3/00
Filed: 1991-05-16
Abstract: To bring the potential of one body (1a), like an aircraft fuel tank, to that of another (1b), like the tank of a refuelling vehicle, without the occurrence of sparks, a conductor (3) in series with a variable resistance (5) is used. The resistance is in series with the conductor and the second body. The resistance is set extremely high before the conductor is attached to the first body, and then is gradually reduced to zero.

Title: Pressure equipment for hydraulic pressure controlled fuel injection valve - utilises the operating behaviour of compressed air driven piston pumps to form a static pressure in the system
Inventor: WEITMANN HERMANN DIPL ING
IPC: G05D16/20
Filed: 1992-02-04
Abstract: In the pressure equipment, the drive air pressure through the converter is controlled over pneumatic/mechanical connection to the air pressure-reduction valve. The equipment utilises the operating behaviour of compressed air driven piston pumps to form a static pressure in the system without the need for a further control unit. Slight variations of pressure caused through piston stroke of the pumps and pressure impacts caused by the needle stroke of the injection valve are compensated by the insertion of a diaphragm pressure store. The valve is arranged in distributor for reciprocal protection of the pressure system. USE/ADVANTAGE -For heavy-oil powered combustion engines' fuel injection valves opening pressure control. Reliable, relatively inexpensive and can be universally installed.

Inventor: THIMM-DORNER GEB SCHORP
IPC: B29B17/02
Filed: 1992-03-05
Abstract: Thermoplastic particles are sorted from a material stream by allowing them to adhere to a thin walled heated sorting drum. The drum is horizontal and consists of a thin sheet metal sleeve (14) attached to support rings (11,12) at its edge. The support rings are carried in portal frames and driven in synchronism, esp. through gear rings.

Title: Wireless infrared transmission between telephone appts. and handset - transmitting in opposite directions during non-consecutive quarter time frames sepd. by empty or signalling slots.
Inventor: MOSES KLAUS DIPL ING
IPC: H04M1/737
Filed: 1992-03-11
Abstract: The transmission method for a fixed telephone appts. involves a clock generator (TG1) driving a multistage counter (Z1) acting as a frequency divider.
