Title: Divisible sliding clasp fastener - has insert slid sideways into housing during manufacture
Inventor: ALBERT MAURICE
IPC: A44B19/60
Filed: 1979-09-17
Abstract: The divisible sliding-clasp fastener comprises two strips, on each of which a row of plastic members is injection-moulded, in addition to which there is an insert on one side at the bottom and a housing at the other. The insert (4) and the housing (5) are so shaped that during production the insert can be slid sideways into the housing. The insert can have two ramp faces at the sides to allow this, acting against mating faces on the housing. The memebers (3) can be initially continuously injection-moulded on the strips, after which reinforcing members (2) are glued onto the latter. The sliding clasp is then fitted, the housing, insert and top stops are formed, and the strips are finally parted off into lengths.
Patent DE-2940560-A1 (DE)
IPC: B23Q11/00
Filed: 1979-10-06
Abstract: The loader comprises a cross-shaped mandrel holder (18), in which the ends of the arms carry mandrels (12-15) which carry the work piece from a supply station (10) to a work spindle, from there to a turning station (5), to another working spindle and, finally, to a clearing station (11). The driving of the mandrel holders is performed by direct current motors, which are controlled by a programme control incorporating a position closed loop regulation in relation to the machining time of the lathe. The opening and closing motions of all the mandrels provided on the mandrel holders (18) and the turning station (5) are originated from a hydraulic motor of which the control for the opening of the mandrels depends on a fixed time interval element; the starting of the opening is started by the workpiece itself. For the opening, the time element is activated in response to the machine time of the lathe. The loader travels are digitally controlled.

Title: Capacitor measuring circuit compensating for lead capacitance errors - uses integrating operational amplifier with capacitor in feedback path and AC voltage input
Inventor: NICOL KLAUS DIPL PHYS DR
IPC: G01R27/26
Filed: 1980-02-28
Abstract: A circuit having a capacitor (1) in the feedback path of an operational amplifier (2) which has an ohmic impedance (3) connected to its inverting input is applicable to analogue computation as an inverting integrator. The circuit is developed for use as a simple effective capacitance measurement circuit. The feedback capacitor (1) is a measurement capacitor. An a.c. voltage is applied to the amplifier (2) inverting input via the ohmic impedance (3) and a measurement instrument (22) is connected to the output of the amplifier. The capacitance measurement takes place practically independently of the connector capacitance magnitudes and variations. The arrangement enables dynamic capacitance variations to be measured. The earthing capacitance effect is negligible if an operational amplifier closely approximating the ideal is used. Connector capacitance compensation circuits can be incorporated.

Title: Vehicle with starter automatically switched in - restarts engine when accelerator pedal is depressed, using speed-dependent switch operated by relay
Inventor: OBERPICHLER GERD
IPC: B60W30/18
Filed: 1980-04-10
Abstract: The vehicle has its starter (16) switched in to restart the combustion engine after its no-load phase when the accelerator pedal is depressed. The accelerator pedal operates a switch (8) which in turn closes a relay (12,13) that closes the circuit containing the starter. A speed-dependent switch (9) by-passes the accelerator-pedal switch shorting it out below a river speed and thereby causing the clutch to disengage and decouple the engine from the gears. Operating the clutch pedal causes another switch (10) to disable the accelerator-pedal switch and the by-passing switch. The clutch is disengaged by disabling the circuit (5) that supplies it with current.

Title: Safety arrangements in data transmission devices
Inventor: HALPERN JOHN WOLFGANG
IPC: G07F7/08
Filed: 1981-03-24
Abstract: In equipment which has a storage space or a portable data carrier for recording data and a control station for accessing the storage station for changing the stored data, for example a telephone device which is started by the user via a coin and in which a recording is produced via the device in correspondence with the call made, a safety test device operates via a reference signal and a test signal which is fed into the storage station, the reference signal selecting a corresponding test signal in the control station for comparison with the signal of the storage station. The control station supplies a weighting test signal for comparison in one operating mode and a non-weighting test signal in another operating mode. These two operating modes come into force in various sequences, the control station evaluating the response signals of the data carrier with respect to the respective part-test signals before the reading out or loading of the stored data or instructions is enabled as determined by the evaluation.
Patent DE-3113049-A1 (DE)
Title: Rubber bearing
Inventor: BOESE KARLHEINZ ING GRAD
IPC: B60G7/02
Filed: 1981-04-01
Abstract: A rubber bearing for the suspension arms of motor vehicles is composed of two bearing elements which are placed against one another and each have an inner metal sleeve with end collar, of two layers of rubber with an end shoulder and of an intermediate sleeve which is provided with a flange and is situated between the two layers of rubber. The axial length of the outer layer of rubber is greater than or equal to half the eye length after it has been pressed into the eye of the suspension arm. The rubber bearing is set, with respect to the inner sleeve and the layer of rubber, with a characteristic curve which is markedly progressive when axial forces occur, and exhibits smooth and increasingly hard load/deflection behaviour. To achieve this, the end shoulder of the outer layer of rubber contains a loosely inserted shim in a circumferential slot. During pressing in, initial shearing strain occurs in the cylindrical rubber bearing part, with a circumferential airgap between the end collar and the end shoulder, and airgaps appearing on both sides of the shim. Small axial forces are therefore only absorbed by the cylindrical rubber bearing part as thrust. In the event of increasing, relatively large forces, the airgaps are closed, the end collar and the end shoulders now absorbing axial forces in addition and causing increasing hardening of the characteristic curve.
