Patent DE-2950969-A1 (DE)
Title: Cleaning system using abrasive solid particles - ejected from cleaning jet and selected to dissolve in recirculated cleaning float
Inventor: VETTER KLAUS DIPL ING
IPC: A47L15/00
Filed: 1979-12-18
Abstract: The cleaning system has at least one cleaning float jet carrying abrasive solid particles. The cleaning float is recirculated. The abrasive particles are made wholly or at least largely of a material that is soluble in the cleaning float or that forms a fine suspension in it. Their lifetime in the cleaning float is a multiple of the recirculation time. The aqueous cleaning float is disposed of directly into the waste-water system after use without prior cleaning. The appts. is suitable for cleaning equipment used in food preparation. A pulse generator supplies an integrator to serve as a measure for the speed of delivery of the cleaning granules.
Patent DE-3004628-A1 (DE)
Title: IC engine cooling system - injects water into cylinder on down stroke after ignition
Inventor: NOWATZYK HANS
IPC: F02B47/02
Filed: 1980-02-08
Abstract: The operating system is for a conventional IC engine where the fuel is burned directly in the cylinders. After ignition has taken place and while the piston is on the down stroke, a liq. vaporised by heat, preferably water, is injected. The heat from combustion can be used for vaporisation, increasing the effective stroke, and the quantity of water injected can be proportional to that of the fuel, being also controlled by the cylinder block temp. The injected water assists with cooling of the engine.
Patent DE-3010147-A1 (DE)
Title: Industrial gas-fired burner digital control - controls air feed in dependence on variable gas feed responsive to output demand
Inventor: BALGAR GUENTHER ING GRAD
IPC: F23N1/02
Filed: 1980-03-15
Abstract: The control delivers a defined amount of air to the gas feed adjusted in turn by a setting motor control in dependence on the required energy output of the burner. The received gas vol. and the corresp. air vol. are held as digital words in respective binary stores. The stored gas vol. is compared with a digital word defining the required gas vol. and the result of this comparison is used to control read-out of the corresponding air vol. from the second binary store. The read-out value is then fed by a D/A converter to the setting control for the air feed. A digital processor may be used to obtain the setting for the latter setting control by interpolation of specific stored values, to provide greater flexibility.

Title: Self-monitoring inductive proximity switch - monitors moving parts of machinery and has damping sensing coil to test own functioning
Inventor: KAMMERER HEINZ ING GRAD
IPC: H03K17/945
Filed: 1980-08-02
Abstract: The switch has its own self-testing or self-monitoring circuitry to check its functioning. This circuitry contains an electrically-switched oscillation damping circuit. The oscillator contains an induction coil which is short-circuited by the damping circuit. Only that part of the coil lying between a tapping and one end is short-circuited. This is accomplished using a transistor switch in the damping circuit. The transistor's collector is coupled via a resistor to the tapping and its emitter is connected to one end of the coil, which is also coupled to one supply pole. The transistor's base is connected via a resistor to a test switch. The test switch applies the opposite supply pole to the transistor's base, thereby turning it on and shorting out part of the coil. A filtering capacitor is connected into the transistor's base/emitter circuit.

Title: Device for permitting fuel to be saved at traffic light systems
Inventor: SCHAMAREK GEORG
IPC: G08G1/096
Filed: 1981-02-24
Abstract: At traffic light systems, at present considerable amounts of fuel are consumed in the engines of motor vehicles without any economic use since the said engines are operated when the vehicle is stationary. By dividing up the traffic light signal phases into supra-regional, generally applicable time phases which are of uniform length and which are indicated to motorists by display means, for example illuminated characters or else a digital or analog display, in a mechanical fashion or by means of a computer-controlled display panel, the latter are capable of estimating whether an economical saving in the fuel is possible by temporarily switching off the engine of the motor vehicle. The display of the timing phase is to take place either as a device which is supplementary to existing traffic light systems or in newly designed or newly constructed traffic light systems which are used for general traffic control but also in special cases such as roadworks and railway crossings.
