Title: Device for monitoring current failure in at least one phase of a three-phase load
Inventor: STIPAK KARL
IPC: H02H7/09
Filed: 1982-04-20
Abstract: A device for monitoring current failure in at least one phase of a three-phase load contains a signal generator circuit which is connected to the phases and derives measurement signals from the phase voltages which measurement signals are compared with a reference voltage in a comparator circuit which is connected to the signal generator circuit. A switching stage is controlled by the comparator circuit, by means of which switching stage the voltage supply to the three-phase load is switched off when a current failure is detected in one phase. In order also to be able to monitor three-phase loads which induce an e.m.f. in one phase in the event of a current failure, the signal generator circuit contains at least one filter device which produces measurement signals corresponding to the frequency spectra of the phase voltages.

Title: Ignition system for internal-combustion engines
Inventor: KOPPER WERNER DIPL ING
IPC: F02P3/045
Filed: 1982-07-17
Abstract: An ignition system is proposed which is used to ignite the fuel-air mixture which is compressed in a cylinder of an internal-combustion engine. In this ignition system, the primary winding (5) of an ignition coil (6) is connected in series with an electronic interrupter (7). Current is passed through the primary winding (5) as soon as a threshold-value switch (15) is in a switched-on state. The threshold-value switch can be controlled by an AC generator (27) connected upstream. Of the AC voltage signal (Uc) of the AC generator (27), the curve section (Ue) preceding a peak value (Ud) is used to switch on the threshold value switch (15) and the curve section (Uf) following the peak value (Ud) is used to switch off the threshold value switch (15). In this case, a superimposed voltage (Ug) can according to the invention be added to the AC voltage signal (Uc) on reaching the switching-on value (Ua), and this superimposed voltage is switched-off again on reaching the switching-off value (Ub). <IMAGE>

Patent DE-3233729-A1 (DE)
Title: Infrared remote control receiver for receiving remote control signals pulse-code modulated onto an RF carrier frequency
Inventor: GROBER STEFAN
IPC: H03J9/06
Filed: 1982-09-11
Abstract: These remote control signals consist of a word of several individual pulses. The signals sent out are converted into proportional current pulses by a photodetector. These current pulses are amplified in a preamplifier and a capacitively coupled further amplifier stage comprising a base-controlled common-emitter transistor. So that the output pulses of a command word have the same lengths independently of the amplitude of the received signal and the interference and noise signals present, the operating point of the transistor of the further amplifier stage is shifted in dependence on the amplitude of the received signal to be amplified, via a high-impedance resistor connected to the base and connected to an operating-voltage source, in such a manner that the peak values of the input signals to be amplified are clamped to the base-emitter voltage.

Title: Process for producing sleeves for receiving audio or video discs
Inventor: MARTH EGON
IPC: B31B160/10
Filed: 1982-11-26
Abstract: Sleeves for receiving flat articles, such as for instance audio or video discs, are known, the side flaps of which have a width of approximately the thickness of a disc for joining front side and rear side of the sleeve and are adhesive bonded to each other in an overlapping manner. The production of these sleeves is made difficult by the tendency of the side flaps after the folding operation to spring back in the direction of their original position before the adhesive has set. According to the invention, the side flaps are cured of this tendency to spring back by being folded inwards through 180 DEG , pressed down and folded back again before the actual folding operation.

Title: Arrangement for testing jet outlet openings on ink print heads for blockage or contamination in ink printing mechanisms
Inventor: SCHULZ HARTMUT ING GRAD
IPC: B41J2/165
Filed: 1982-12-17
Abstract: Ink printing mechanisms operate with a very low degree of noise and, because of the possible high print frequencies, can be used advantageously as output printing mechanisms in data processing systems. It is a disadvantage with these printing mechanisms that the outlet openings of the outlet jets can be easily blocked by ink slugs. As a result of this, uniform formation of ink droplets which is required in order to achieve a uniformly good print quality is no longer possible. It is the object of the invention to detect the failure of droplet formation of the individual outlet jets at an early point. For this purpose, monitoring characters are produced on the edge, located outside the printing area, of recording carriers (1) which are then scanned by a sensor device (53) consisting of an optical transmitter (61) and an optical receiver (63). By means of a counter unit (65), the points are counted and compared with a reference value point number in a comparator (65). When this reference value point number is not attained, either a warning signal is generated or the machine is switched off so that no more poor quality print can be produced. <IMAGE>

Title: Valve
Inventor: RYZNER CLEMENS DIPL ING
IPC: F16K1/12
Filed: 1982-12-17
Abstract: In a safety valve, especially for gas-carrying lines, there is provided, in order to achieve a compact design and to avoid the risk of explosion caused by escaping gas in the event of a leak in the highly stressed gaskets of the valve, a valve-closing piece having a cylindrical sealed-off guide which is guided in a control chamber formed inside the valve housing, is provided with a feed line for the pressure medium and is connected by means of a control line to the flow-off side of the valve which can be shut off and opened by means of a control valve. As a result, the actuating medium can pass only into the gas system, but not into the open. By means of a throttle bore between the control chamber and delivery side of the valve, the latter can be controlled by means of its own medium.

Title: Hydraulic shut-off valve
Inventor: GOEPPEL HANS
IPC: F04B49/10
Filed: 1983-02-10
Abstract: The hydraulic shut-off valve for the relief of a pump has a control slide valve (36) which is controlled by a pilot valve (44). The pilot valve is acted upon by the system pressure and in addition also by a piston (48), which is subjected to pressure following opening of the control slide valve (36), thereby leading to full opening of the pilot valve. The control slide valve thereupon makes a direct connection from the hydraulic system to the tank (19) by way of a low pressure valve (30) connected downstream of the control slide valve. The speed of the piston (48) acting on the pilot valve can be varied by means of a throttle device (57) connected downstream of it. <IMAGE>
Patent DE-3306176-A1 (DE)
Title: Electromechanical hand-massaging device
Inventor: SVEC MILOSLAV
IPC: A61H7/00
Filed: 1983-02-23
Abstract: The massaging device consists of a core 1 having the form of cylinders which are placed eccentrically upon one another and whose position relative to the shaft of the core is defined by a freely selectable, regularly repeating angle. The core is cast or pressed as a single article from a heat-deformable material, together with a shaft 5 leading from one end and an annular blocking element 3 on the same end of the core. Elastic rollers 2 are then fitted on the core 1, which rollers turn freely about the core. In order to facilitate the fitting of the rollers, the individual edges of the core 1 and the edges of the hole in the rollers can be rounded, Figures 4 and 5. The fitted rollers are secured on the free end of the core by means of a second blocking element 3, which is fastened by means of a screw 4 to the end of the core. The shaft of the core is then attached to a transmission gear which is driven by an electric motor, so that the core 1 turns about its own axis. The arbitrary rotation of the rollers is prevented by means of an elastic skin drawn over the rollers, so that the rollers exert a rotating movement without turning about their own centre. <IMAGE>

Title: Device for controlling a motor of a windscreen wiper
IPC: G01N21/43
Filed: 1983-04-23
Abstract: A device that serves to control a motor 61 of a windscreen wiper, said motor 61 driving a windscreen wiper 62 which is arranged on a window, in particular of a motor vehicle. For this purpose, a measurement section with a transmitter 16 and a receiver 19 is provided for waves, in particular infrared light, which can propagate in a wireless fashion. The window is arranged in the measurement section and then influences the propagation of waves between transmitter 16 and receiver 19 when moisture, for example rain, is precipitated on it. A comparator 57 which is provided in the receiver 19 compares the signal S which comes from the transmitter and is influenced by the coating on the window with a reference value SA and when a predetermined signal deviation  DELTA S from the reference value SA is exceeded it switches on the motor 61 of the windscreen wiper. In this case, the reference value SA is adjusted during the subsequent wiping operations of the windscreen wiper 62 to a second reference value derived from the extreme values of the received signal S. (Fig. 4). <IMAGE>
Patent DE-3317205-A1 (DE)
Title: Device for preheating motor vehicles
Inventor: MOLT WOLFGANG DR ING
IPC: B60H1/00
Filed: 1983-05-11
Abstract: The windows of motor vehicles must be kept free of ice and condensation in the winter by heating - usually using warm air. In order to bridge the time between the cold start and the reaching of an operational temperature of the engine which is adequate for heating, the heating energy is supplied in this phase by means of a latent heat accumulator. The latter is charged in the travel mode by the cooling water and also gives off its heat to the latter during the discharging process. The existing heat exchanger serves for heating the air. The latent heat accumulator is prevented from discharging itself when the vehicle is stationary by virtue of its installation in a convection-inhibiting arrangement in the cooling water circuit. <IMAGE>

Patent DE-3326252-A1 (DE)
Title: Pressure control valve
Inventor: LANG ERNST-WALTER ING GRAD
IPC: G05D16/06
Filed: 1983-07-21
Abstract: A pressure control valve which serves for controlling a fluid pressure in a system, in particular for controlling the fuel pressure in a fuel injection system, is proposed. The pressure control valve comprises a valve diaphragm (41), which interacts with a valve seat (44) on a valve seat body (39). The valve diaphragm (41) separates a spring chamber (42), with a system compression spring (43), from a system pressure chamber (40), into which protrudes the valve seat body (39), displaceable in an axial bearing location (45). The end of the valve seat body (39) remote from the valve diaphragm (41) is designed as a valve disc (47) and protrudes into a collecting space (46), in which it opens a first sealing seat (48) to a greater or lesser extent with respect to a return line (49). On the valve disc (47) there acts a closing compression spring (50), which loads the valve seat body (39) towards the valve diaphragm (41) and presses a sealing shoulder (54) against a second sealing seat (53), blocking off a throttling gap (51) and a throttling opening (55). With the valve diaphragm (41) lifted off the valve seat (44), fluid flows via a channel (52) into the collecting space (46). When the fluid system is switched off, fluid can continue to flow out via the throttling gap (51) and the throttling opening (55) to the collecting space (46) until the valve disc (47) is pressed in a sealing manner against the first sealing seat (48) and shuts off the return line (49). <IMAGE>
