Patent DE-3010312-A1 (DE)
Title: Control device for fuel injection pump - has concentric double piston to displace timing characteristic by driver's action, or in response to independent parameter
Inventor: KRIEGER KLAUS
IPC: F02D1/18
Filed: 1980-03-18
Abstract: The device controls the timing of a fuel injection pump and uses a pump (9) driven at engine speed. Fuel is pumped via a damping restriction (13) into a chamber (14) to move an inner piston (6) and hence actuate a control rod (8). The inner piston is contained within an outer piston (3) which is actuated by the pressure in a chamber (23). Fuel is supplied to this chamber from a line (20) by a variable throttle (22), or from an independent source, so that a different engine control parameter can be superimposed. The characteristic curve relating the injection timing with speed can thus be displaced in a parallel manner by an independent parameter.

Title: Method for producing a clock or watch housing
Inventor: UMEZAWA SEIJI
IPC: G04B37/22
Filed: 1981-04-18
Abstract: A method for producing a clock (watch) housing contains the steps of placing the contact points of a front ring (2) and of a clock (watch) housing (1) opposite one another, of exerting pressure on the contact points via electrodes (3, 4) and of feeding current in the form of pulses onto these electrodes (3, 4) until the contact points have melted. The current, in the form of pulses, makes it possible for the front ring (2) and the clock (watch) housing (1), with the exception of the contact points, to cool during the breaks in current. The process does not therefore require a water cooling system as is necessary in conventional processes. <IMAGE>
Patent DE-3119515-A1 (DE)
Title: Circuit arrangement for operating a bistable relay with a monostable switching characteristic
Inventor: KIMPEL ROLF-DIETER DIPL PHYS
IPC: H01H47/22
Filed: 1981-05-15
Abstract: In order to achieve a monostable switching characteristic, the excitation winding (RL) of a relay is switched between the outputs of two electronic switching stages (OP1, OP2), as a result of which a pulse is alternately applied to one connection or the other of the winding (RL), depending on the change in the control voltage. The conversion of sudden level changes of the control voltage (Us) into pulses can be carried out either by means of a capacitor (C1) connected in series with the excitation winding (RL), or by means of an RC element in the input circuit of the electronic switching stage. Also, a single switching stage can be used instead of the two electronic switching stages (OP1, OP2), if one connection of the excitation winding is connected to zero voltage and the single electronic switching stage is supplied with two supply voltages of opposite polarity. <IMAGE>

Title: Washing machine with fresh-water inflow
Inventor: BOCK HELMUT DIPL ING
IPC: D06F39/08
Filed: 1981-12-15
Abstract: In a washing machine having branches, directed into the washing-agent chambers of a feed tray via a free air stage, of a fresh-water inflow, the fresh water of which is first to fill the sump in the tub of the washing machine at the start of the filling operation, there is the problem of ensuring this so-called prefilling in as simple a way as possible. This problem is solved in that there is arranged in the free air stage (17, 18), in front of at least one branch mouth (11, 12), a movable diaphragm (23, 33) which assumes, at the start of the filling operation, a position in which fresh water can be deflected directly to the tub by bypassing the associated washing-agent chamber (19, 20) and, after a water level filling the sump has been reached in the tub, a normal position in which the fresh water cannot be impeded. <IMAGE>

Title: Control device for a recording circuit, in particular in an electronic clock circuit
Inventor: AZZAM NADIM DIPL ING
IPC: G04G5/02
Filed: 1982-04-02
Abstract: A control device for a recording circuit (9), in particular in an electronic clock circuit, by means of which prescribable control information can be generated depending on actuation as additive or subtractive correction information (27), is intended to be designed in conjunction with various possibilities of realisation for input signal transmitters (15) in such a way as to enable the delicate management of a large quantity of information in conjunction with a low additional outlay on circuitry for the generation and transmission of information. For this purpose, each of the two possible signs of the correction information (27) is assigned its own signal transmitter (15.1 or 15.2). A down counter (13) is counted down from an initial counting position (2<x>) between in each case one pair of successive actuations of one of these signal transmitters (15), and the final counting position thereby reached, which is thus proportional to the time interval (24) between two successive actuations of the signal transmitter (15), is processed as correction information (27). The signal transmitters (15) are preferably constructed as contact paths (37) which can be closed as a function of the direction of rotation by setting stem cams (45). The down counter (13) is preferably realised in a control circuit (6) with a microprocessor structure whose data bus sets a main memory area into the initial counting position (2<x>), starting from which the downward counting is performed using the program clock (23). <IMAGE>
