Title: Control circuit for remotely excited DC voltage transformer - applies load signals also reference and output signals to equalising amplifier
Inventor: FREYE KLAUS-DIETER
IPC: H02H7/12
Filed: 1979-09-21
Abstract: The control system uses a pulse width modulator and transformers to obtain signals corresponding to the load current, connected to current evaluator and controller units. Also connected to the modulator is a voltage regulator and a clock pulse generator. The low resistance secondary windings (Lsn) are each in series with an evaluating diode (Dan) and connected to corresponding integrating capacitors (C21) connected between the input and output of an equalising amplifier (V). At one input of this amplifier is applied a voltage proportional to the load current and at the other input a reference signal and summing signal proportional to the output voltage. This voltage (Ua) is applied to a resistance (R2) and (diode) D1 in sereis, and the reference voltage (Uref) is applied to a resistance (R1), both paths being connecters to a common input.

Title: Steam or IC operated cam plate engine - has trunnions in ends of radial pistons engaging grooves in shaft-mounted plates
Inventor: BERGER WOLFGANG DR ING
IPC: F01B9/06

Title: Electromagnetic bell with variable sound volume - has end-stop ensuring correct sound even at low volume
Inventor: ANTON HORST
IPC: G10K1/064
Filed: 1980-09-25
Abstract: The bell (or other sound generator) has a drive system comprising a permanent magnet, a drive coil and a flat armature parallel to one axis of the coil. The flat armature has ferromagnetic flaps on both sides that cooperate with the yoke faces belonging to the drive coil. A clapper is rigidly fixed to the armature and strikes two bells. The clapper's position can be set via the cam of a volume-setting wheel. An end-stop is connected via a spring to the yoke at that half of the drive coil that is open when the bell is at rest. The end-stop cooperates with one face of the yoke. The advantage lies in the correct functioning of the bell even when the clapper blocks at low sound volumes.

Title: Subdivision of semiconductor wafer - obtains higher yield by dividing into chips of different sizes
Inventor: KRAFT WOLFGANG
IPC: H01L21/78
Filed: 1980-12-20
Abstract: Semiconductor elements are usually manufactured on a wafer which is subsequently divided up into equal chips. This results in a higher reject rate among the chips from the perimeter of the wafer. A higher yield is obtained by taking larger chips from the central area and smaller, hence more numerous chips, from the perimeter. A circular wafer is subdivided into chips of different sizes. The largest (A) is taken from the centre, with smaller chips (B), and still smaller chips (C), taken from outer areas.
