Title: Method of and apparatus for treating water
Inventor: HINE DAVID MICHAEL
IPC: B01D61/42
Filed: 1986-02-17
Abstract: A method of treating water, particularly potable water, is provided which is characterised by filling chambers 13,14 separated by a semi-permeable membrane 12 with water 17 containing dissolved impurities and passing electrical current through the water in order to reduce the concentration of undesirable anions (e.g. F or No3) in the water in at least one of the chambers.

Title: Vehicle deceleration indicator
Inventor: HEPBURN BARRIE
IPC: B60Q1/44
Filed: 1986-04-08
Abstract: A pulse generator 1 produces pulses at a frequency proportional to the vehicle road speed, and the pulses are counted for a predetermined period by a counter. The current count and the previous count, stored in a memory 4, are compared in a comparator 3 which in response to a negative difference causes a switch 5 to energise a deceleration indicator 6. The indicator 6 may be turned on only if each of a succession of counts is less than the preceding count. The indicator 6 may be the brake lights, hazard lights or reversing lights, or any combination thereof. The system may also keep the indicator lights on when the vehicle is stopped, actuate the reversing lights on sensing reversing, and actuate the hazard lights on sensing very rapid deceleration or very rapid acceleration (e.g. wheel spin). <IMAGE>

Title: Electrical devices provided with circuit-breakers
Inventor: DEWSNAP PAUL MICHAEL
IPC: H01H71/04
Filed: 1986-04-11
Abstract: An electric switch or socket assembly has a "circuit-breaker" and reset device, and a blocking member which in one position allows supply of current but prevents reset of the circuit-breaker, and in another position prevents supply of current but allows resetting of the circuit-breaker. The blocking member may comprise a resiliently biassed slidable shutter plate 60 arranged to block the reset device 38 when the apertures of a socket assembly are held open by plug pins in sockets 10, 12 so that the plug has to be removed to allow operation of the reset button 38 which cannot be depressed whilst the shutter plate 60 is moved to the open position. Alternatively the blocking member may interlock with a switch rocker preventing its movement to the "on" position if the reset button is pressed and also preventing operation of the reset button if the rocker is in the "on" position (Figure 7, not shown). <IMAGE>

Title: Fibre optic transversal filter
Inventor: BYRON KEVIN CHRISTOPHER
IPC: G02B6/28
Filed: 1986-06-13
Abstract: An optical transversal filter includes a number of signal inputs, e.g. from antennae (A1 to A4) of a radio DF system from which optical versions of the signals are launched into multimode fibres (MF1 to MF4) by lasers (L1 to L4). The fibres are of equal length and each has its other end aimed at a photodetector array (PD1 to PD4), with means to select in each array which detector is to be read to derive the signals to be processed.

Title: Toner density sensing device for image forming equipment
Inventor: SAWAYAMA NOBORU
IPC: G01N21/47
Filed: 1990-07-12
Abstract: A device 17 incorporated in image forming equipment senses the density of a reference toner image RT formed on a photoconductive element 1 by illuminating the toner image with light from a source 18, and by detecting the light reflected from or transmitted through the toner image RT with a light-sensitive element 118 whose output is used to determine when the supply of toner needs to be replenished. The device 17 has first and/or second restricting arrangements 34, 134 for intercepting part of the light issuing from the source 18 and part of the light directed toward the light-sensitive element 118, respectively. Each restricting arrangement has a pair of restrictions (D1 and D2, or D3 and D4) with the restriction close to the source or light-sensitive element (D1 or D3) having a large diameter the restriction remote from the same (D2 or D4). <IMAGE>

Title: Trench box for shoring
Inventor: COLLINS JOHN
IPC: E02D17/08
Filed: 1990-10-22
Abstract: A trench box for shoring comprises two panels (10) interconnected by four extendable and retractable struts (30, 32) in two pairs. Between each pair of struts (30, 32) is a multi-leaf spring (38), which is connected at mutually opposite  &cirf& nds (40, 42) of the leaf spring (38) to the end parts (26, 28) of the two struts (30, 32). The connection of the leaf spring (38) 12 to each strut (30, 32) is rigid, so that where the leaf spring (38) adjoins the struts (30. 32) it extends perpendicularly to the strut. Since the pair of struts (30, 32) are always parallel, bending stress induced in the leaf spring (38) due to pivoting of either strut (30, 32) is transmitted through the leaf spring (38) to the other strut (32, 30) so as to effectively stiffen the pivotal connections of the struts (30, 32) to the panels (10). <IMAGE>

Title: Drive shaft for a motor vehicle
Inventor: BEIER RUDOLF
IPC: B60K17/22
Filed: 1991-04-04
Abstract: A drive shaft, e.g. for use in the drive line of a motor vehicle comprises a central portion disposed between, and having a larger outside diameter than two end portions (11, 12) which are adapted to be connected to universal joints, wherein the central portion over its length Rm has a substantially constant wall thickness and an outside diameter which varies along its length in a manner analogous to the amplitude of lateral displacement of the shaft when undergoing bending vibration in a second or higher harmonic mode. This enables the distribution of cross sectional area of the shaft along its length to be such as to meet strength requirements and at the same time have a natural resonant frequency into a range where it is subject to minimum external excitation, thereby minimising vibration and noise in use. <IMAGE>

Abstract: A gaseous fuel flow control arrangement comprises a gas rail 1, a plurality of disc-type gas laps (7 to 10) formed integrally with the gas rail for controlling the flow of gas between a gas inlet (3) and respective gas outlets (15), and a thermostatically controlled gas tap 12 formed integrally with the gas rail 1, the thermostatically controlled gas tap 12 comprising a first part 21 mounted on the gas rail 1 and including a rotatable disc valve member 13 for controlling gas flow from the gas inlet (3), and a second pan 22 mounted on the gas rail 1 and including a thermostatically controlled unit 37 which is coupled to the first part 21 and which controls a valve member 34 and thus the flow of gas from the first part 21 to a thermostatically controlled gas outlet 19. The valve member 34 is coupled to the disc member 13 by a rod 25 and to a screw-threaded spindle 36 secured to the unit 37. Rotation of disc member 13 causes rotation of the valve member 34 with axial movement thereof relative to a valve seat 33 resulting from the screw-threaded connection with the spindle 36. The unit 37 is itself rotatable with respect to the housing of the second part 22 for calibration purposes. <IMAGE>
