Title: Method for testing the tightness of gas pipework, especially in houses, and test set for carrying out this method
Inventor: POHLMANN ROLF
IPC: G01M3/28
Filed: 1988-05-05
Abstract: For testing the tightness of gas pipework, especially in houses, a measuring and test method is used in which, in the place of a gas meter in the gas supply pipe, a measuring device is used with which the gas flow and gas pressure in the gas pipework can be measured. After the connection of the measuring device, gas is supplied to the gas pipework system to be tested until a stationary state of the gas flow and of the pipework pressure, which can be read on the measuring device, is reached. After that, a measurement is carried out for a predetermined time period which yields not only the instantaneous values of the gas flow but also characteristic average values of the flow quantity such as measured values of the pipework pressure on the basis of measured values read on the measuring device.

Title: Circuit board with a printed electric circuit and a transparent protective layer and also a process for producing the same
Inventor: CARNOVALE ALFREDO
IPC: H05K3/28
Filed: 1988-08-25
Abstract: Process for producing a circuit board with a printed electric circuit and at least one protective covering layer, in which a thin copper foil is applied by hot lamination to the exposed surface of a circuit board bearing a printed circuit by the said copper foil being fastened in an adhesively and cohesively bonding manner on the surface of the printed circuit by means of a film of a resin which is transparent and free from glass fibres; the copper foil is chemically etched in order to remove most of it, so that only exposed metallic elements intended for the forming of terminals, contacts and the like remain; the exposed metallic elements are then connected by means of metal-clad bores, rivets or the like to locations intended for the purpose of circuit parts printed on the underlying layers. The circuit board thus produced, printed with an electric circuit, has on at least one surface a protective layer of a resin which is transparent and free from glass fibres, which makes it possible to identify individual conductor tracks of the directly underlying printed circuit by appearance and, if appropriate, to interrupt them by means of a cutting tool.

Title: Power control system
Inventor: THOMS ULRICH DR ING
IPC: F02M3/07
Filed: 1988-10-19
Abstract: A power control system for an internal combustion engine, especially of passenger motor vehicles, is described, in which at least one throttle valve (2), arranged in an intake line (1) of the internal combustion engine and actuatable by an accelerator pedal (3), and a device for controlling the idling charge (5) are provided. The device for controlling the idling charge (5) has a control valve (8) arranged in a bypass line (6) bypassing the throttle valve (2), which valve can be actuated by a control device 10 for the passage of a charge which results is in a predetermined, essentially constant idle speed of the internal combustion engine, when the accelerator pedal is in the idle position with throttle valve essentially closed. In order to extend the control range of the said system without major hardware cost, it is proposed that the device (5) be additionally designed to control and limit the speed of the internal combustion engine close to the full load position of the accelerator pedal (3) by influencing an additional charge flowing by way of the bypass line (6) when the throttle valve (2) is essentially fully opened. <IMAGE>

Title: Programme-controlled domestic washing machine with a water-softening device
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: D06F39/02
Filed: 1988-11-19
Abstract: A complete flushing-in of washing agent must be guaranteed even when the water-pipe pressures are low. Known washing machines with a water-softening device, on account of their water-pipe routing, have flow losses which are too high. The washing machine according to the invention is designed in flow terms in such a way that a thorough flushing-in of washing agent is ensured even at low pipe pressures. The water inflow (1) with flow regulator (2) branches into a pipe string (3), which leads to a solenoid valve (5), a free air stage (6''), an ion exchanger (6') and directly into the tub (7), and into a second parallel pipe string (4) which is laid to a washing-agent flushing-in container (8) with solenoid valves (9, 9', 9'') and which thereafter likewise opens directly into the tub (7). The full water-pipe pressure is therefore available to both pipe strings (3, 4). The flow passes through the pipe strings (3, 4) in a manner staggered in time by means of their programme-controlled solenoid valves (5, 9, 9', 9''). The programme-controlled domestic washing machine with a water-softening device can be used in areas both with high water hardnesses and with low water-pipe pressures. <IMAGE>
Patent DE-3841088-A1 (DE)
Inventor: MESENICH GERHARD DIPL ING
IPC: F02M69/08
Filed: 1988-12-07
Abstract: We propose a device for the injection of fuel into the induction tube of combustion engines where the fuel is transported to the individual injection locations by means of thin conduits and with the assistance of air. Fuel-metering is by means of an electromagnetic valve which is directly mounted inside the injection device without requiring a valve housing. The electromagnetic valve features a tilt-armature and several valve seats. Alternatively, several valves may also be anticipated, which are then installed directly in a fuel manifold. In addition, a suitable air pump for the generation of a compresed air supply to the injection device, is described. The air pump is mechanically driven by the combustion engine with synchronous revolutions. For purposes of adapting the rated output of the air pump to the requirements of the injection device, a larger dead-space volume and a choke location in the intake pipe are features of the air pump.

Title: Deaerator for a liquid containing gases
Inventor: PRAGER ULRICH DIPL ING
IPC: B01D19/00
Filed: 1989-02-18
Abstract: Deaerators (1) in which the deaerated liquid is added to another liquid stream have a deaeration chamber (6) containing floats (15, 18) arranged one above the other, of which the lower float controls the outflow of the degassed liquid and the upper float controls a vent valve (19). In the case of liquid vigorously frothing in the deaeration chamber (6), undesired liquid exit can occur from the vent valve (19). This is to be avoided. For this purpose, the upper float (18) is composed of a material having a lower specific gravity compared to that of the lower float (15). In addition, the upper float (18), when the lower float (15) is not elevated, does not lie on this. As an additional safety precaution, the deaerator is further furnished with a second deaeration chamber (25) which is separately controlled by a float and is connnected downstream of the first deaeration chamber (6). The deaerator is particularly suitable for use in the return line of an oil burner. <IMAGE>

Filed: 1989-04-07
Abstract: Process for the reconstitution of refrigerating unit housings mainly comprising mouldings of plastic (of unfoamed and foamed plastic) for the purpose of reuse and/or disposal of the plastic, the refrigerating unit housings, from which the motors, compressors, metallic pipe systems and the like have been removed, being disintegrated in a shredder stage and the iron parts subsequently being removed from the shredded material. The refrigerating unit housings are introduced into the shredder stage via an adequately gastight airlock and are disintegrated in the said shredder stage to a piece size of 100 to 250 mm. The shredded material is introduced into a cutting mill stage and disintegrated there to a piece size of less than 10 mm. The cut material is introduced into an air separator stage. From the air separator stage, on the one hand the particles of unfoamed plastic are discharged as granules and on the other hand the particles of foamed plastic are taken away. The particles of foamed plastic are introduced into an eddy mill stage. The ground material is introduced into a cyclone stage. The reconstituted foamed plastic is drawn off from this stage. Exhaust air which has taken up the contaminating gases is extracted from the shredder stage, the cutting mill stage and the air separator stage. The contaminating gases are removed from the exhaust air by adsorption and/or freezing and/or burning. <IMAGE>
