Patent GB-2251740-A (GB)
Title: Induction motor control arrangement
Inventor: RAY KEVIN
IPC: H02P25/14
Filed: 1990-10-10
Abstract: Although an induction motor under full load acts essentially as a resistive load, under no load the motor tends to act predominantly as an inductive load. Accordingly, although no output work is done by the motor, significant currents flow in the motor. These significant currents cause substantial I<2>R losses in the motor and the electrical supply system. In order to reduce these losses, a standard form of universal motor speed control circuit/light dimmer circuit is included in series with the motor and the speed control circuit has a fixed or preset resistor 22. The circuit is set so that, at full load, the circuit chops the first 36 DEG  of each half cycle. This produces a small reduction in full load power. However, under no load, the circuit causes a substantial reduction in the RMS current through the motor, and thus the I<2>R losses are reduced. A capacitor 20 and a diac 24 can be an integrated circuit (26, Fig 2) and a triac 14 may also be integrated with the capacitor and diac (28, Fig 3). <IMAGE>

Title: FIFO memory system
Inventor: LIVAY AVIEL
IPC: G06F5/06
Filed: 1992-06-06
Abstract: A FIFO memory system 10 for handling transmission queues in a serial digital communication system comprises a plurality of blocks of memory 20a-c, 21a-e, blocks 20a-c being assigned a plurality of FIFO memories, and blocks 21a-e forming a pool of unassigned blocks of memory. A memory management means (LLT, PT) controls the addition of the unassigned blocks of memory from the pool to a FIFO memory on writing to the FIFO memory whereby the size of the FIFO memory is selectably variable, and the return of a block of memory from a FIFO memory to the pool once the contents of the block of memory have been read. In this way a FIFO has additional memory only when it needs it by dynamically applying small blocks of memory to the FIFO on request and, thus, overflowing and underrunning can be avoided whilst minimising the size of the FIFOs. <IMAGE>

Title: Cycle trailers
Inventor: JONES GARETH EVAN LYN
IPC: B62K27/14
Filed: 1994-02-08
Abstract: A cycle trailer 1 collapses into an inverted-U configuration with side-wing sections 7, which carry the trailer wheels 10 and which in the erected condition extend laterally from a central section 6 of the trailer chassis, folding downwardly of the section 6 with the wheels 10 folded up and under the sections 7. The chassis is coupled via a universal joint 17 to a towing arm 3 that is pivotally attached to the cycle rear-axle 4, pivoting of the arm 3 about the axle 4 to move it upwardly and then forwardly over the rear wheel 2, drawing the collapsed trailer 1 upwardly behind the arm 3 to stow it in the inverted-U configuration straddling the rear wheel 2. Freedom for pivoting of the collapsed chassis downwardly with respect to the arm 3 for this movement is achieved by changing the clamped orientation of the central pin 18 of the joint 17 from vertical to horizontal during the collapsing procedure. <IMAGE>

Title: Multi-quadrant charge domain synapse cell
Inventor: CASTRO HERNAN A
IPC: G06G7/60
Filed: 1992-05-26
Abstract: A semiconductor charge domain synapse cell has a capacitor (35) coupled between an input line (11) and an intermediate node (39). A high-to-low voltage transition applied to the input line (11) causes charge transfer from one summing line (51) to the intermediate node (39) through a first device (31) having a programmable threshold. A second device (32) then transfers the charge from the intermediate node (39) to another summing line (52) in response to the next low-to-high transition of the input. The amount of charge transferred is proportional the amplitude of the pulsed input, the programmed voltage threshold, and the capacitance value. The basic cell is shown to be extendable to two-quadrant and four-quadrant operation (30). <IMAGE>
