Patent GB-2190211-A (GB)
Title: Adjustable single-mode optical-fibre attenuator
Inventor: LEACH JOHN STUART
IPC: G02B6/26
Filed: 1986-05-08
Abstract: A single-mode optical-fibre attenuator is constituted by a straight length of single-mode fibre (1) with a reduced-diameter drawn-down portion (3) of high bend-loss sensitivity. This is embedded in a resilient medium such as a silicone resin (9) contained in a rigid box (5). Local elastic deformation of the surface of the silicone resin (9), as by a plunger (10), produces an elastic deformation (via a bend) of the embedded fibre thereby providing switchable attenuation in a length of fibre which previously exhibited low insertion loss. The resin (9) has a lower refractive index than the fibre and the deformation attenuates core modes by providing coupling to cladding modes. <IMAGE>

Title: Circuit breaker relay energisation
Inventor: WHITEHOUSE JOHN HENRY
IPC: H01H47/04
Filed: 1987-09-08
Abstract: A relay for a circuit breaker comprises a solenoid having an armature and a coil to move the armature between first and second condition, the armature carrying at its free end a pair of relay contacts which in the rest condition of the relay are open. To close the relay, a voltage is applied to the coil of the relay to move the armature to close the contacts, and to hold the relay contacts closed, against the action of a spring, whilst the device is in use. In accordance with the invention, the relay comprises a means to apply a voltage to the relay coil to move the relay from its first to its second condition, said means being operative to apply a higher voltage to move the relay from its first towards its second condition, and to apply a lower voltage to retain the relay in its second condition. Conveniently this is attained by the use of a circuit which includes a capacitor (C1) and means (6) to restrain the capacitor against discharge until such higher voltage level is reached, said restraining means preferably comprising one or more solid state devices which adopt a conducting condition when said higher voltage level is reached, and which remains conducting at said lower voltage level. In this manner a smaller coil may be used to move the relay to its second condition, and/or the relay may be used to operate against a more powerful load, and/or a lower power dissipation may be achieved whilst the relay is held in its second condition. <IMAGE>

Patent GB-2215221-A (GB)
Title: Sensing positions of chess and like pieces
Inventor: WINKLER ERIC
IPC: A63F3/02
Filed: 1989-01-30
Abstract: A game includes a board having a number of defined positions each provided with an isotropic field strenth sensor such as a reed switch which has open and closed positions depending upon the presence or absence of a magnetic field, and two sets of playing pieces. All pieces have a magnet with its N-S axis substantially upright to provide a magnetic field which will open or close the sensor when a piece is positioned on the associated board position. To avoid a lack of detection if one piece is quickly replaced by another piece, the pieces of one set have the N pole facing downwardly whilst the pieces of the other set have the S pole facing downwardly. Then, by detecting the opening and closing of the sensors including momentary open and closed positions during capture or replacement of a piece of one set by a piece of another set, movement of pieces can be determined. <IMAGE>

Title: Building aid
Inventor: RICCIO ANDREW
IPC: E04G21/18
Filed: 1989-07-04
Abstract: In building brick walls, it is known to use what are known as "profiles", a profile consisting essentially of a staff provided with attachment means for attaching it firmly, in an accurately vertical position, to the base of a wall which is being built. Such a profile is often placed at the outside of an angle where two walls meet, so that its inner vertical edge defines the outer edge of the corner. The present invention provides a profile assembly which utilizes two substantially standard spirit levels 10, 20 (already a part of a bricklayer's kit - of tools) as part of the assembly, joined by a connector 25, which may include locking means. The assembly may include side glasses to aid in setting it vertical. One or more fixing brackets and/or a stand-off bracket may be provided, for attaching and locating the assembly at the footing of the angle of two walls. An adjustable slider may be provided, for locating a string for guiding bricklaying. The assembly is cheap and can be readily disassembled. <IMAGE>

Title: Fluid flow control system
Inventor: ALI ABDULATIF ALI
IPC: F17D5/06
Filed: 1989-09-26
Abstract: A fluid flow control system for limiting wastage of fluid comprises a flow sensor (114) a solenoid valve (110) and a controller (112). The controller includes timing means for timing the period during which fluid is flowing in the system. When a tap is opened and fluid is flowing the controller receives a signal from the sensor and starts timing the fluid flow. After a preset time has elapsed a buzzer (116) is sounded and then after a further preset time unless the controller is reset the solonoid valve operates to cut off the fluid supply. <IMAGE>

Title: Calibrating receivers of an antenna array
Inventor: BODONYI JANOS
IPC: H01Q3/26
Filed: 1989-09-28
Abstract: In an antenna array of large dimensions, such as might be used for high frequency radar, the antennas 1a, 1b, will be connected by short feeders 2a, 2b, to receivers 3a, 3b, which will consequently be distributed over a considerable distance. To calibrate such an antenna array to compensate for variations in the transfer functions of the receivers will necessitate the same test signal being fed into each element in turn to measure the receiver output, and this could be time consuming and hence reduce the time available for use of the array. To overcome this disadvantage, a loop 5 is connected at various tappings to the feeders 2a, 2b, the respective antennas being disconnected, and sinusoidal tones are injected into the left hand and right hand ends of the loop. The outputs of the receivers are measured, and provides a measure of the transfer functions of the receivers and hence enables discrepancies between them to be corrected. <IMAGE>

Filed: 1991-09-09
Abstract: The conditioner (1) treats feed with steam and includes a plurality of steam lines (10) that can inject steam into a chamber (3) having inlet (5) and outlet (7) openings. Located within the chamber is a rotatable shaft (13) supporting a helical stainless steel ribbon (25) arranged coaxially with the shaft and extending for approximately three quarters of the length thereof.
