Patent DE-2734570-A1 (DE)
Title: Engine indirect fuel injection system - has valve controlling opening of slot located on air meter shaft hub
Inventor: KIENZLE WOLFGANG
IPC: F02M69/48
Filed: 1977-07-30
Abstract: The fuel is sprayed into the air intake upstream of a manually operated throttle valve (4) by means of a jet opening (37) regulated by the movement of an air metering valve (2). The jet opening is formed as a slot on the outer circumference of the air meter bearing hub (36) to spray the fuel upstream to the shutter opening (7) regulated by the air meter surface (11). The fuel regulator slot (37) works with a metering edge (40) in the air meter bearing shaft to give a fuel volume proportional to the air valve movement. The regulator slot is located to spray fuel into the air intake centre via the shortest possible way.

Title: Controlling suction duct pressure of turbocharged engine - uses exhaust blowdown valve whose closing force does not increase as it opens
Inventor: WILL HANS-DIETER ING GRAD
IPC: F02B37/18
Filed: 1977-09-20
Abstract: The arrangement controls the inlet pressure in the suction duct(12) on a combustion engine(6) with exhaust-driven turborharger(18) by means of a blowdown valve(38) arranged upstream of the charger (20) which valve opens at a predetermined exhaust gas pressure. When the engine runs under load, the force tending to close the valve does not increase as the valve opening increases. The valve may be spring-loaded(44) the spring action being opposed by the intake air vacuum acting on a diaphragm(42).

Title: Current control for microwave oven - has integrating circuit and level detector for interrupting pulse train
Inventor: ZINGLER NORBERT
IPC: H02H9/02
Filed: 1977-09-22
Abstract: The application is to circuits for current control using a pulse generator operating a transistor switch. The switch (17) is normally controlled by, for example, a monostable flip flop (22) set by a Schmitt trigger (21) from the rectified main supply.

Title: Halogenating aliphatic hydrocarbon(s) esp. ethylene - by first stage oxyhalogenation then vapour phase halogenation
Inventor: LEITERT FREDERICK CARL
IPC: B01J35/10
Filed: 1977-10-19
Abstract: Non-selective oxyhalogenation and/or oxyhydrohalogenation is effected in a fluidised bed reactor at 340-450 degrees C and 0-14 bars press. with 1-30 secs. contact time to give an intermediate partially halogenated prod. with a halogen/carbon atomic ratio over 1:1. The operating conditions are adjusted to control the halogen/carbon ratio. The prod. is subjected to a vapour phase halogenation with a halogen gas at 400-500 degrees C in the presence of a silica-alumina catalyst to form a final prod. having a carbon/hydrogen atomic ratio of at least 2:1. The halogen/carbon atomic ratio of the intermediate prod. is adjusted to control the amt. of by-prod. hydrogen halide in the vapour phase halogenation. The process is partic. used for prepg. trichloroethylene and perchloroethylene from ethylene. The process has the advantage in flexibility of reaction according to the prod. requirements; partic. with regard to the amt. of HCl produced in the second stage.

Title: Electrical generating element using radioactive rays - by directing onto pn junction through intermediate cpds. which absorb energy and re-emit at longer wavelength
Inventor: GRAVISSE PHILIPPE
IPC: G21H1/12
Filed: 1978-01-18
Abstract: An electrical generating element utilizes alpha, beta or gamma rays issuing from radio-elements, partic. in the form of waste products. The rays are directed onto a p-n junction through intermediate cpds. capable of absorbing all or part of the energy of the rays, and re-emitting at a longer wavelength in the optimal absorption zone of the p-n junction. The said cpds. are distributed in a matrix interposed between the radio-elements and the junction, and made from synthetic material, pref. polymethylmethacrylate not treated against UV, silicone, or PVC, which is transparent to the rays. The cpds. are pref. diphenyloxazol, and/or rhodamine B, and/or alpha-naphthol, and/or one or more substances of the benzene series. The present method permits the generation of an electric current at the p-n junction without deterioration of the junction caused by direct reception of the rays. The apparatus therefore has a much longer life.
Patent DE-2808489-A1 (DE)
Title: Treating waste sludges with calcium oxide - to produce friable solids suitable for landfill or agricultural purposes
Inventor: MANCHAK JUN FRANK
IPC: C02F11/12
Filed: 1978-02-28
Abstract: Waste aq. sludge is converted to a solid, friable and odour-free prod. by treatment with Ca oxide. The sludge is supplied to a treatment zone at a first rate while the Ca oxide is supplied at a second rate releated to the first so that when the sludge and Ca oxide are mixed an exothermic reaction occurs with the evolution of steam to form the desired prod. having pH >=12. The sludge and Ca oxide are introduced at the desired rates to one end of the treatment zone along which they are moved concurrently at a rate such that the reaction has effectively terminated by the time they reach the other end of the zone. The prod. is removed from this end of the zone and the steam is withdrawn. The method may be used to treat either oil well pumps, sewage sumps, or sludge dredged from the bottom of a lake or harbour. The pH value and the heat produced in the treatment zone deactivates any virus or bacteria present in the sludge. Similarly soluble toxic compounds initially present in the sludge are transformed to water insoluble compounds.

Title: Dual system passenger vehicle guided track crossover points - have three tongues kinematically linked to provide guidance according to wheel pressure
Inventor: MEHREN HERBERT
IPC: E01B25/28
Filed: 1978-03-01
Abstract: On roadways providing tracks, with wheel-running surface and laterally protruding cross-guiding stem pieces, the functionally active points are for steerable passenger vehicles which can transfer to guided tracks. This involves fixed sections on inside cross-guiding stems with converging face edges equidistant from the intersection. One points tongue is hinged at this point, with its opposite side flanks correspondingly contoured. On the diverging end faces there is another points tongue extending towards the common third track applicable to the guide face of the relevant outside cross-guiding stem. All three tongues are kinematically coupled together so that the first and one of the other two combine to provide a continuous cross-guiding stem, according to switch position, the other one being lifted out of the way.
Patent DE-2810943-A1 (DE)
Title: Measurement of short wavelength UV radiation - using filter with fluorescent wavelength to re-emit radiation in red range which is then monitored
Inventor: PIRKL JOSEF
IPC: G01J1/58
Filed: 1978-03-14
Abstract: Short wave length ultra-violet radiation from gas discharges is monitored in system containing filters and radiation sensors. The system contains a radiation screen coated with a fluorescent material which is only sensitive to short wavelength UV radiation (UV-C), esp. in line 253.7 mu m. The re-emitted radiation from this is in the red band. It passes through a red filter to remove visible radiation and the resulting signal measured. Used to measure short wave UV in the radiation from gas discharges. Method avoids the problems associated with filters for transmitting only UV which tend to fatigue. Gives a precise measurement very quickly, with easy manipulation and long life.

Patent DE-2816406-A1 (DE)
Title: Extractor hood with fat and odour filters - has warning signals indicating saturation point of filter and stopping filter action
Inventor: FROEHLICH HEINZ
IPC: F24C15/20
Filed: 1978-04-15
Abstract: The control circuit for the extractor hood includes a variable-speed electric motor and a variable oscillator controlled by a signal representative of the speed of the motor so that an output signal with a speed-dependent frequency is produced. This output signal interacts with a meter to produce an output signal with a reading corresponding to the saturation point of the filter. When the output signal from the meter occurs, the electromotor is switched off so that the extractor does not run, which would be dangerous with saturated filters. The output from the meter could also instead of being connected to the motor be connected to an acoustic or optical signal transmitter.
