Title: Ignition circuit for internal combustion engines
Inventor: RODENHEBER RAINER DIPL PHYS
IPC: H03K17/082
Filed: 1986-08-29
Abstract: In an ignition circuit for internal combustion engines with an ignition power transistor, with an ignition transformer as inductive load in the commutator circuit of the ignition power transistor, with an ignition switch, with an ignition pickup circuit and with a limiting circuit for the commutator voltage of the ignition power transistor, the commutator voltage of the ignition power transistor is limited for opening of the ignition switch in such a way that the secondary voltage of the ignition transformer remains below that secondary voltage which triggers a spark plug breakdown, and for ignition triggering by corresponding activation of the ignition pickup circuit the limiting of the commutator voltage of the ignition power transistor, provided for opening of the ignition switch, is inoperative, the ignition circuit instead causing another limitation to be activated, which limits the value of the commutator voltage of the ignition power transistor to a value which on the secondary side of the ignition transformer suffices for spark plug ignition.

Inventor: HEINDL FRIEDRICH ING
IPC: B29C45/17
Filed: 1986-11-04
Abstract: A changing device for the screw cylinder of an injection molding machine. The screw of the screw cylinder is in releasable coupling connection with a drive unit of the machine. For releasing and uncoupling the coupling connection, the screw cylinder including screw can be displaced relative to the injection molding machine essentially transversely of the longitudinal direction of the screw cylinder. Two hydraulic cylinders are arranged spaced apart next to each other symmetrically and parallel to the longitudinal center plane of the injection molding machine. The two cylinders are connected to each other by means of a transverse member. A free space extending forwardly from the drive unit is defined by the two hydraulic cylinders and the transverse members. The free space forms an alignment seat which is open towards the front and towards the back and a longitudinal side. In the coupled position, the screw cylinder is fixable and lockable to the drive unit in this alignment seat. The free space forming the alignment seat of the changing device is open toward the bottom, so that the transverse member which connects the hydraulic cylinders acts on the upper longitudinal side of the hydraulic cylinders.

Title: Arrangement for automatic overcurrent disconnection
Inventor: HAUW-DOEBLITZ HANTJUN DIPL ING
IPC: H03K17/0812
Filed: 1987-07-16
Abstract: An arrangement for the automatic overcurrent disconnection of insulated-gate or field-effect transistors, in which a positive voltage is applied to the gate-emitter path from a drive circuit when a switching-on command is present for the transistor and a negative voltage is applied to the gate-emitter path when a switching-off command is present for the transistor, is to be implemented in a simple manner and should have a short response time. This is achieved by the fact that a thyristor (TS) with an anode connection to the gate feedline or the series circuit, simulating a thyristor in its switching function, of two transistors (T1, T2) with collector connection of the first transistor (T1) is connected to the gate feedline between the gate and emitter feedlines of the insulated-gate or field-effect transistor, in that a zener diode (DS in Fig. 1, D1 in Fig. 2) with cathode-side connection is connected to the gate feedline between the gate feedline and the control electrode of the thyristor (TS) or, respectively, the base of the second transistor (T2) of the transistor series circuit (T1, T2), and that a diode (D in Fig. 1, D4 in Fig. 2) is connected with cathode-side connection to the gate in the gate feedline respectively a feedline for applying a positive gate-emitter voltage. <IMAGE>

Title: Device for measuring the thickness of plate-type workpieces
Inventor: HAGEMANN KARL-HEINZ
IPC: G01B7/14
Filed: 1988-05-11
Abstract: In the automatic charging of working machines with plate-type workpieces, there is a problem, inter alia, of monitoring the charging for the presence of doubles. The thickness measurements so far disclosed in this connection, which are based on inductive measurement principles, cannot be applied for all materials. In a monitoring device (2) according to the invention, contact measurement of a workpiece (4) is performed by means of rolling members (23) which are accommodated in two retaining plates (11, 17) arranged one above another. At a spacing from the said retaining plates (11, 17) an electric measuring device (30) is arranged by means of which the spacing between the retaining plates, which is influenced by the thickness of the workpiece (4) located between the rolling members (23), is preferably scanned in a contactless fashion. Because of the spatial separation of the electric measuring device (30) and the contact scanning of the workpiece (4), the monitoring device (2) can be used independently of the type of the respective material of which the workpiece (4) consists. <IMAGE>

Title: Rotor of an eccentric screw pump
Inventor: HENNEN ERSNT
IPC: F04C2/107
Filed: 1988-10-07
Abstract: A rotor (4) of an eccentric screw pump (1) customarily has, at an end projecting out of the stator (3) of the eccentric screw pump (1), a coupling part (5, 6) with a recess (5, 6), into which another coupling part, constructed on a driveshaft as counterpart thereto, is to be inserted. On the said projecting end, the rotor (4) has the same outer configuration as over its remaining length, and the other end, located in the stator (3), has the same coupling part, consisting of the recess (5'), as the first end. The eccentric screw pump (1), which is subject to non-uniform wear over its length, i.e. to less wear in the inlet-side region and to more wear in the discharge-side region, can be turned around with the new rotor (4) after a certain time. In this case, the rotor (4) need only be displaced in the stator (3) in such a way that its previously projecting end comes into the stator (3) and the end previously located in the stator (3) now projects. <IMAGE>

Title: Appliance for automatically discharging a solution for cleaning, deodorising, disinfecting and/or other purposes into the toilet bowl after each flushing operation
Inventor: LIESK INGRID
IPC: E03D9/03
Filed: 1989-02-28
Abstract: The invention relates to an appliance which, suspended in the toilet bowl and controlled by the flushing water, automatically meters an active-ingredient liquid into the toilet bowl after each flushing operation. The mode of operation is as follows:   at its lower end, an active-ingredient container has a vertically displaceable bar with cavities. When the appliance is in the rest position, said cavities are located outside the active-ingredient container. If the toilet is flushed, then the flushing water collects in the collecting container (1). By virtue of the quantity of water accumulated, a float which is fixedly connected to the displaceable bar is pressed upwards together with said bar, this, at the same time, causing the cavities of the displaceable bar to move into the interior of the product container and there to be filled with product. After the flushing operation, the collecting container runs empty. Float and bar move back, by virtue of their dead weight, into the rest position again. The quantity of active ingredient accumulated in the cavities runs out into the toilet bowl in droplets.
