Inventor: DEHARDE HORST
IPC: H01H3/00
Filed: 1990-10-26
Abstract: It is endeavoured further to reduce the size of medium-voltage switchgear, but on the other hand it is intended to improve the switching power. To this end, it is necessary to adapt the associated drives for medium-voltage switchgear to these new conditions. The invention shows a means by which a snap-action drive for medium-voltage switchgear is designed with few individual parts which can be housed in a U-shaped supporting rack 21. Two driveshafts 1 and 1' are provided, which are designed as hollow shafts and in which thrust rods 12, 12' unlock thrust locking bolts 18, 18', by means of an operating device 37 via guide pieces 13, 13' which are located in the driveshafts 1 and 1', which results in a force-fitting connection being produced between the drive and the moving contacts. The operating device 37 is installed together with a locking plate 23 such that incorrect handling is prevented. Such a snap-action drive can be used in medium-voltage switchgear, preferably in metal-encapsulated, compressed-gas-insulated switchgear. <IMAGE>

Title: Memory circuit for storing lightly populated vectors with small number of non-zero elements - contains memories for non-zero elements and corresp. position information, binary counters for address computation and data output control muliplexers
Inventor: REISSIG GUNTHER
IPC: G06F17/16
Filed: 1990-11-22
Abstract: The circuit stores lightly populated vectors during cyclic readout of the components of the vectors with only a small number of components not equal to zero. A memory (RAM1) of K x b bit stores non-zero elements and a memory (RAM2) of A x 1 bits stores information about the positions of the non-zero elements. Binary counters compute the addresses and multiplexers perform address conversion and control data output from the non-zero element memory. An n-bit comparator and a combinatorial circuit are used to select the memory and counter and control the multiplexer. USE - E.g. for use in documentation systems involving sequence of hardware arithmetic units, e.g. systolic matrix-matrix and matrix-vector multipliers for key-word indexes.

Title: Chocolate kneading machine for chocolate mfr. - has flow of liq. in machine jacket, controlled by difference between its temp. and required valve modified by drive motor load parameter
Inventor: LEUTHOLD JOHANNES
IPC: A23G1/16
Filed: 1991-01-10
Abstract: The machine has a trough contg. at least one shaft (3,4) driven by a motor (M) and provided with kneading tools. The motor is controlled by a control unit (P) in accordance with a motor output parameter measured by a sensor (1). The trough is provided with a double wall (2) which has an inlet (E) and an outlet (A) for a temp. control fluid. The temp. of this fluid is controlled in relation to the difference between its actual (14) and required (S) temps. The energy transmitted by the kneading tools is controlled by swtiching on a motor controller if the motor output parameter, or its rate of increase, exceeds a predetermined value. The required fluid temp. value (S) is provided by the operating programme and is corrected by a computer (R) in relation to the actual value of the motor output parameter. This correction is equal to the product of a manually input quantity (K) and the percentage of the actual value of the motor output parameter in relation to its maximum value. USE/ADVANTAGE - Used in the mfr. of chocolate. The required duration of the kneading process is minimised and an increased temp. of the chocolate at the time of the phase change from dry to liq. is reliably avoided.
