Patent GB-2076203-A (GB)
Title: Taximeters
IPC: G07B13/00
Filed: 1981-05-14
Abstract: A fare accumulation system has two mode operation, below a break speed being on a time basis and above that speed on a distance travelled basis. Distance pulses and a sawtooth timing wave are produced, and above the break speed distance pulses occur with sufficient frequency to be used in suppressing the full timing wave, which is reset at each distance pulse. The distance pulses then determine the accumulation of fare units. Below break speed, the timing wave can reach a peak between distance pulses, and these peaks also generate fare accumulation. Any further time before the next distance pulse is also accounted for by adding a partial fare increment to the accumulator, corresponding to the instantaneous amplitude of the sawtooth at that next distance pulse. <IMAGE>

Title: Pipe spacer
Inventor: LYCAN GOODWIN A
IPC: B23K31/02
Filed: 1982-05-14
Abstract: A pipe spacer 10 is positioned between the end 22 of a pipe 20 and an internal annular shoulder 26 of a bore of a fitting 24, into which bore the pipe is inserted prior to welding the pipe to the fitting at 28. The spacer 10 comprises a ring-shaped body 12 which is split, at 14, to define a pair of spaced ends 18. The body 12 is formed with three, equi-spaced resilient protrusions 16 which serve to increase the effective thickness of the spacer 10. The body 12 has an outer diametrical dimension approximately equal to the outer diametrical dimension of the pipe 20, whereby the body abuts either the pipe end 22 or the fitting shoulder 26 at the regions of the protrusions 16. The protrusions 16 are sufficiently compressible to maintain a spacing between the pipe 20 and the fitting shoulder 26 during pipe expansion resulting from welding the pipe to the fitting 24. The spaced body ends 18 are spaced sufficiently apart to accommodate circumferential expansion of the body 12, to prevent abutment of the spaced body ends during the pipe expansion as the protrusions 16 are compressed. <IMAGE>
Patent GB-2120567-A (GB)
Title: Rotary drum filter
Inventor: LEIGHTON MILTON DALE
IPC: B01D33/00
Filed: 1982-05-21
Abstract: The periphery of an inward-flow filter drum is divided into axially extending cells, each having two conduits connecting its interior with a valve which applies suction and reverse pressure gas as appropriate to each cell in turn as the drum rotates, one conduit being connected to a leading part and the other to a following part of each cell in the direction of rotation. The end of each following conduit which is most distant from the valve opens into a respective chamber 82, formed as part of a divided annular vessel inside the drum, which serves to receive residual liquid from the conduit when reverse pressure gas is fed thereto, thus preventing said liquid from being blown violently through the filter cloth which covers the cells and damaging it. Each chamber communicates by a passage 85 with an opposite chamber, so that the gas pushes the liquid from the following conduit into a chamber 82F, in the cake-removal position, then through passage 85 to a chamber 82A located just before the position which its cell emerges from the liquid being filtered, and out of chamber 82A through its following conduit, which is under suction, to the valve and filtrate outlet. <IMAGE>

Abstract: A leakage detector for detecting leakage current through an insulator from a high voltage conductor to a normally unearthed support member.   The leakage detector is connected by means of a wire (18) to earth and by means of a wire (16) to the support member. A switch S2 in series with a resistor RS is connected between wire (16 and 18). The detector includes a differential amplifier (2) having its non-inverting input connected to a DC voltage source VB and its other input connected to earth. The amplifier (20) output voltage VX, which can be adjusted by variable resistor VR1 is presented to one input of a comparator (24). A further switch S1 in series with a resistor R2 is connected in parallel with variable resistor VR1. The wire (16) is connected through a potential divider R3, R4 to a rectifier and low pass filter (23) to produce a DC voltage VY, proportional to the voltage on the support member, for application to the other input of comparator (24). In operation with switches S1 and S2 open resistor VR1 is adjusted so that VX is slightly less than VY. Resistors R2 and RS are chosen so that when switches S1 and S2 are closed voltage VX remains less than VY when the leakage current from the support member is less than a desired maximum, otherwise a signal appears on line (25) to activate an alarm. <IMAGE>
