Title: Flat film cassette for camera - has resilient housing with internal guides for easy film removal, also with light sealing strips
Inventor: STEMME OTTO DIPL PHYS DR
IPC: G03B17/26
Filed: 1979-03-07
Abstract: The film cassette for a set of flat light sensitive film strips, has a casing made of non-transparent material designed for easy handling of the strips and insertion into and removal from the camera.

Title: IC engine torque converter and damper - has inertia mass distributed between planetary pinions of epicyclic gear train
Inventor: SCHUELER GERHARD DR ING
IPC: F16H33/08
Filed: 1979-04-11
Abstract: The moment converter is particularly for use between an internal-combustion engine and a driven machine. It functions in place of the conventional rigid flywheel as a torsional-vibration damper, overload protection device, elastic coupling for taking up the load and automatic torque converter. The flywheel and gearbox are combined into a single epicyclic gear train whose planetary pinions have the inertia mass distributed between them. It makes use of inertia forces, so that when two rotary movements are superimposed rotation of the inertia weight takes place about two different axes.
Patent DE-2918174-A1 (DE)
Inventor: BRUCKMANN ERHARD ING GRAD
IPC: B65H67/04
Filed: 1979-05-05
Abstract: 1. A method for automatically starting to wind an running thread (4), which is under tensils stress and which is guided via a traversing element (3), on to a spool (2) or sleeve, characterized in that, with no change in the position of the axis of the spool during the winding-on process, the thread is gripped, at a point in time when the traversing device (3) has essentially reached an end position, by a conveying device and is deflected by a movement of the conveying device parallel to the axis of the spool in the direction of the other end position of the traversing element (3) and the thread is deflected beyond this position in such a way that it is gripped by a gripper (9) which revolves around the axis of the spool approximately through the same plane as the front face of the spool, which faces the deflecting device (3), at a rotational speed which is lower than or the same as the speed of the rotation of the spool, and in that after several windings have been placed on the driven empty spool (2) without overlapping the traversing motion is changed in such a way that a second layer is wound on top of the first layer, by means of which the spool (2) itself produces tension in the thread and the thread which hitherto has been drawn off further by the spool (2) to be freshly wound is cut.
Patent DE-2921793-A1 (DE)
Title: Semiconductor device esp. MISFET prodn. - using silicon nitride film obtd. by direct nitriding to prevent ion implanted impurity migration during heat treatment
Inventor: ITO TAKASHI
IPC: H01L21/265
Filed: 1979-05-29
Abstract: Semiconductor device, esp. MISFET prodn. involves implantation of an impurity in a semiconducting Si substrate and heating. The novel feature is that a Si3N4 film, esp a gate insulating film of the MISFET, is produced on the substrate by direct thermal nitriding, so that the total amt of ion implanted impurity is retained at the surface of the substrate after heating. Specifically, the Si3N4 film prevents redistribution of the implanted impurity from the substrate into the Si3N4 film when the substrate is heated to activate the impurity and correct damage to the substrate caused by ion implantation.

Title: Carrier frequency amplifier output offset voltage reduction - using operational amplifier and FETs to measure reduction of DC voltage stage
Inventor: SCHERFF ROLF UWE ING GRAD
IPC: H03F3/45
Filed: 1979-06-20
Abstract: A circuit reducing the output offset voltage of a direct voltage amplifier stage in a carrier frequency measurement amplifier uses operational amplifiers for minimal offset and increased measurement accuracy. The circuit is more economical than conventional devices. This is achieved by using cheaper components and reducing setting up work. An operational amplifier (ICI) demodulator has one input grounded synchronously with the carrier frequency measurement voltage and drives a second, direct voltage operational amplifier (IC2). The inverting input (E2-) of the direct voltage operational amplifier (IC2) and the non-inverting input (E1+) of the demodulator operational amplifier (ICI) are connected by a resistor (RZ) and FET switch (FET2). The demodulator amplifier non-inverting input (E1+) is also connected via a further resistor (R4) and FET switch (FET1) to ground. The sum of the two resistors above far exceeds the direct voltage amplifier input resistance (R2) value.

Title: Magnetic signal generator for electronic ignition system - employing ferromagnetic rotor passing between permanent magnet and hall element
Inventor: BRAND GUENTER
IPC: H03K17/97
Filed: 1980-03-03
Abstract: The signal generator is principally intended for installation in the distributor for an i.c. engine ignition system. It replaces the contact breaker. A yoke (7) of magnetic material has a flange at each end (8,9), one carrying a permanent magnet (2) and the other a Hall element (3). The yoke is fastened to a mounting plate in the distributor housing. The rotor (1) consists of a strip to magnetic material (4) bent to form flanges at each end (5,6). Yoke flanges and rotor flanges lie on concentric circles. There is an air gap between the rotor flanges and the permanent magnet and Hall element. The rotor is attached to the distributor spindle (10) of non-magnetic material. As it rotates the flux circuit between permanent magnet and Hall element is alternately made and broken causing the latter to give a pulse output for controlling the electronic ignition system. The yoke mounting is typically rotatable through an arc by a conventional advance and retard mechanism.

Title: Contact system for bimetallic switch - has blades secured to plate and resistive layer then bent for connection to bimetal strip
Inventor: ARTMANN JOACHIM DIPL ING DR
IPC: H01C1/144
Filed: 1980-03-20
Abstract: The contact system has two contact blades secured by rivets to an insulating plate with a securing strip on top and projecting outwards front and rear. Each blade is bent downwards towards a bimetal strip with a resistive layer on one side. The two blades are connected to a voltage source resulting in a generation of heat in the bimetal strips. The connections are made at the ends of the blades remote from the resistive layer, where they project from the insulating plate. The other ends are soldered to the resistive layer. The insulating plate can then be swung over by bending the blades so that its securing strip can be welded to the underside of the bimetal strip.

Title: Universal joint transmitting torque from one shaft to another - has curved bridging element of graphite fibres of I=shaped cross=section
Inventor: WEIBLE WARREN WALTER
IPC: F16D3/72
Filed: 1980-04-15
Abstract: A universal joint, of the constant velocity type is for use in drive trains of front wheel drive vehicles. The joint includes a pair of members attachable to two shafts to be joined, with a curved elongate bridging element connecting the two members. The bridging element extends in a curve from 180 deg. up to several turns in progressing from one of the members to the other. The bridging element has high resistance to bending both parallel, and perpendicular, to axes of the two connected shafts. Simultaneously it has low resistance in torsion or twisting. These characteristics enable the bridging element to transmit torque from one shaft to the other and to twist or flex to accommodate angular misalignment between the two shafts.
