Title: Infinitely variable ratio transmission - is for agricultural or contractor's machinery and includes adjustable cone belt drive and friction clutch
Inventor: SCHOPF WALTER DIPL ING
IPC: F16H61/662
Filed: 1992-11-19
Granted: 1994-05-19
Abstract: The drive mechanism comprises an engine, a steplessly-adjustable cone-disc transmission unit, and a friction clutch. The discs are thrust hydraulically in the axial direction so as to grip the belt between them, pressure being supplied by a pump via a control valve. Return flow from the valve takes place via a torque sensor, and is throttled by movable valve components dependent on load. The clutch (2) is actuated hydraulically by a first ram (27), which is supplied by a hand-operated second ram (28, 30), the latter opening a non-return valve (33), so as to disengage the clutch. Flow from the first ram to the second to engage the clutch is via an adjustable throttle valve (35), whose plug (36) moves in opposition to a spring (40) bearing against a fixed support under the effect of the return flow pressure (19) from the control valve (14). Thus throttling is increased or reduced in proportion to the return flow pressure. USE/ADVANTAGE - Transmission for agricultural or contractor's machinery, allowing sufficiently high slipping torque to be selected without severe loading.

Title: Sepn. column process and assembly
IPC: B01D3/16
Filed: 1994-06-01
Granted: 1995-10-26
Abstract: A sepn. column (1) process and assembly incorporates a liq. distributor over a zone (2) enclosing solid bodies. A gas or vapour phase flows upwards through the zone (2) in contraflow to a descending liq. flow. The incoming liq. within the column (1) is converted to a flow of liq. and bubbles (27) by mixing a portion of the gaseous phase into the incoming liq.. The sepn. column (1) incorporates a pressurised fluid inlet system (5) and associated adjacent gas inlets above the zone (2) enclosing the solid bodies. Relatively low gas pressures prevail in the gas inlet zone. Ascending gas and descending liq. mix in the vicinity of the heat plate (24) and the gas entry slit (21). A shaped sieve or similar supplies a bubble flow for the gasified liq. below this zone.

This signal is also sent through negative feedback channel to unit for modeling an inverse polarization signal generation. Inhibiting field leads to stabilization. If amplitude of control instruction is increased, then first correcting mechanism starts its operations and decreases pulse amplitude. If amplitude of input signal is further increased, then inter-channel correction mechanism helps electric current correction one. Still further increase of input signal amplitude starts third correction mechanism, polarization one. EFFECT: increased reliability of neuron system for control of muscles. 8 dwg

Granted: 1994-09-30
Abstract: FIELD: computer technology. SUBSTANCE: during test checking of the memory, defective memory cells are clamped in address code registers. Digits are marked in clamped address codes, which have constant unit and zero values. These values are inverted subsequently. Order numbers of digits of address are changed by switching address buses in such a way, that marked digits would correspond to senior digits of memory address. These digits are clamped by unit values in senior digits of register in area of defective memory. During operation, input address code is compared with code, fixed in register of defective area of memory. If this code is less than input one, "INVALID ADDRESS" signal is generated, which blocks access to memory. EFFECT: improved efficiency. 4 dwg, 2 tbl
