Title: Current limiter for switches - has auxillary switches coupling RC cct. across switch and coupling in LC cct. respectively
IPC: H02H3/02
Filed: 1969-02-22
Abstract: The current limiter, for switches, contains a first auxiliary switch which closes when the voltage across the opened main switch reaches 10% of its maximum value and connects a parallel RC circuit across the main switch. When the voltage across the RC circuit capacitor reaches a given level a second auxiliary switch is closed and connects a parallel LC circuit across the main switch. As soon as the LC capacitor has taken over from the RC capacitor, the first auxiliary switch opens and the RC capacitor then discharges at leisure over its resistor. The invention replaces the high value capacitor of high rated voltage of the circuit given in P1763487 by more economical means.

Title: Quality control monitor for machined component edges - uses optical gauge with photo-electric measurement of surface irregularity
IPC: G01B11/30
Filed: 1972-01-05
Abstract: The quality control monitor for the inspection of machined edges consists of a ventilated light-box (17) and photoelectric detector (28).

Title: Computer controlled fibre pulling machine for fabrication of optical fibre probes for scanning near-field optical microscopy
Inventor: CHVETS IGOR
IPC: G02B21/00
Filed: 1994-09-06
Abstract: Optical probe is the single most important element in any scanning near-field optical microscope. The size of the aperture at the end of the probe and the angle of the tapered part of it are critically important since they determine the amount of light transmitted through the probe and resolution in the near-field optical imaging. The probes are usually made by pulling an optical fibre with simultaneous heating of it. We have developed a computer controlled machine which allows for a much better degree of control in the pulling parameters and duration and timing of the heating pulses. This machine is used for making optical probes for near field microscopy and it can also be used for making the optical fibre sensors.

Title: Coin-operated telephone
Inventor: MCMAHON STEPHEN
IPC: H04M17/02
Filed: 1996-07-12
Abstract: A coin-operated telephone is disclosed having a coin-operated actuating mechanism which comprises circuit elements coupled directly to a controller (IC1) so that coin parameters are accurately detected to identify or validate a coin. One detector comprises an oscillator circuit (L2,C55) generating a preset resonance frequency and amplitude. A coin passing the oscillator causes fluctuations which are compared to predetermined fluctuation values to identify the coin. An optical detector (D29,D30, Q34,Q35) is used to establish light beams across the path of a coin, to produce a series of pulses dependent on the dimensions and speed or acceleration of the coin. The pulse parameters are compared directly with previously stored reference parameters in memory elements associated with the controller (IC1). The oscillator detector (L2,C55) and the optical detector (D29,D30,Q34,Q35) are coupled to provide enhanced accuracy for validating coins. The controller may also enable and disable individual circuits in the telephone as necessary to minimise current drawn by the telephone.

Title: A synchronising circuit for a PBX for synchronising a PCM clock signal with basic rate ISDN network signals
Inventor: BRADY PETER MARTIN
IPC: H04L7/033
Filed: 1997-09-09
Abstract: A communications circuit (1) of a PBX comprises a control circuit (3) for controlling the circuit (1) and the interface circuit (4) which operates under the control of the control circuit (3) for receiving eight ISDN lines on inputs (1) to (8) of the interface circuit (4). Eight layer one integrated circuit chips (5) are provided, one for each ISDN line. Each layer one integrated circuit chip (5) outputs a line synchronous clock signal which is derived from the basic rate ISDN network signal on the corresponding ISDN line. A synchronising circuit (2) comprises a digital phase locked loop circuit (IC 24) for providing synchronised PCM clock signals one of which is applied to an input (1) of a digital switch matrix (6) for clocking ISDN signals through the digital switch matrix (6). The phase locked loop circuit (IC 24) outputs the synchronised PCM clock signal which is divided in a digital counter (IC 23), (IC 30) and (IC 31) to appropriate frequencies. The synchronised PCM clock signal is fed back to the digital phase locked loop circuit (IC 24) where it is compared with one of the line synchronous clock signals which is selected by a multiplexer (IC 26). The two signals are compared in the digital phase locked loop circuit (IC 24) and single pulses at the same frequency as the synchronised PCM clock signal are added to or deleted from the synchronised PCM clock signal to push the signal into phase and phase lock the signal with the selected line synchronous clock signal.

Abstract: A group control for an elevator system assigns immediately destination calls which were entered at a floor lying behind the car in the direction of travel of the car and for a floor which lies ahead of the car. The group control includes a call memory having a first register for storing the calls of like direction of travel entered ahead of the car, a second register for storing the calls of opposite direction of travel and a third register for storing the calls of like direction of travel entered behind the car. A control circuit is activated each time a call is entered such that a call of the same direction of travel is written, according to its position with respect to the car, into the first or third register. The allocated calls of the third register are transferred into the second register on the first change in direction of travel of the car and into the first register on the second change in direction of travel so that they can be detected by a selector addressing the call memory.
