Title: Stereo amplifier system with independently controlled channels - enables frequency characteristics of true stereo signals to be dynamically altered or stereo effect created from mono input
IPC: H04S1/00
Filed: 1984-06-29
Abstract: The left (Lin) and right (Rin) inputs to the amplifier system are fed via identical circuits to audio loudspeakers (Luit, Ruit). The signal is fed in parallel to the two pre-amplifiers (A1, A2). The output of one amplifier (1) is fed directly and via a phase-shifting circuit (12) to the mixing output amplifier (A3). The output (5) of the other pre-amplifier (A2) is fed to a signal amplitude envelope detector (13) and integrator (14,15,16) to control a saw-tooth oscillator (17). The oscillator controls the phase-shift and provides a visual signal via a comparator (11) and LED (18). The frequency characteristic can be changed by varying the integration capacitance (14,15).

Patent NL-8700679-A (NL)
Title: Optical current sensor using Faraday rotation effect - uses double reflection surfaces to compensate for stray magnetic fields
IPC: G01R15/24
Filed: 1987-03-23
Abstract: The current carrying conductor (1) passes through the centre of a sensor body (5) made of SF10 glass. A beam (2) of light from the end of an optical fibre (7) passes through a lens (8) and a polarisation filter (3) before being reflected around the glass sensor by the prismatic reflection surfaces (6) at three of the corners of the sensor. The magnetic field around the conductor alters the polarisation of the beam in proportion to the current. The beam leaves the sensor and passes through another polarisation filter (4) and lens (10), before being transmitted along another fibre (7) to the signal analysis equipment. Two prisms are located at each corner so that the beam is reflected through 90 deg. twice at each corner. This modification minimises the effect of stray magnetic fields from outside the meter.

Title: LIMI-Q cable protection system
IPC: H02H3/08
Filed: 1993-01-29
Abstract: The invention relates to a second generation of the PRO- TEC-2000 cable protection system as already described in patent application 8902169. The aim is in full agreement with the known PRO-TEC-2000 system, but is distinguished from its predecessor by simplicity, cost and compactness. The purpose of the LIMI-Q cable protection system is to ensure the safety of human and animal life in case of direct contact with live conducting parts owing to a defect in the said parts, without the need for large investment in underground cable work and/or protective conduits. The LIMI-Q cable protection system is constructed from a current-measuring transformer, current- measuring relay, and as required, a time relay and electrical unit provided with a trip coil for each phase and group leading therefrom. The interruption occurs based on overcurrent instead of short-circuit current as in conventional protection.

Title: Traffic-light installation
Inventor: VROOMEN ANTOON GERARD JOSEPH W
IPC: G08G1/087
Filed: 1994-06-21
Abstract: Traffic-light installations are generally known and are used for regulating traffic coming from various directions. According to the customary approach, the cycle in which the traffic lights are processed is either made to proceed according to a fixed schedule or is allowed to be affected to some extent by the traffic volume (amount of traffic). If a police car, fire engine or ambulance approaches such a traffic junction with its siren/flashing light switched on and at high speed, the chance of the traffic light for this vehicle being green is about 50%. By providing a control unit of the traffic light installation with a receiver and providing the vehicle in question with a transmitter it is possible to alter the cycle of the traffic light installation.

Title: Control circuit for governing a "cotton" machine using punched tape
IPC: D05B/
Filed: 1989-11-07
Abstract: "Cotton" machines which produce knitted clothing are governed by punched tapes which contain information on all the mechanical actions which the machine has to carry out during the making of garments. These punched tapes have various lengths depending on the size of the article to be made and on the latter's shape. The present invention allows up to a 90% reduction in the length of said punched tapes and also makes it possible for the same punched tape to be capable of being used to make articles of different sizes, which solves the problems which arise from handling and storing long punched tapes in addition to reducing production costs through the reduction in the number of tapes required to produce a range of articles of different sizes. In addition to the aforesaid, the present invention makes it possible, in the event of breakdown, for the "cotton" machine to be capable of repair without giving rise to the loss of the work already carried out, which may be completed at a subsequent time, which is currently a fairly slow operation which in practice is not carried out.
