Patent GB-2038063-A (GB)
Title: Bank note identification
IPC: G07D7/00
Filed: 1979-10-31
Abstract: Apparatus for identifying the denomination of a bank note comprises a sensor 14 which senses light reflected from an incremental area 16 of a bank note 10 to produce an output which is passed to a storage 24 at intervals. When sufficient sample outputs have been stored in the storage 24 a control 28 causes each sample to be compared in a comparator 30 with a number of previous samples taken in a pre-selected sequence so as to produce a multi-bit correlation number. Each correlation number thus formed is then compared with reference multi-bit numbers derived from scanning a corresponding section of a number of notes of the different denominations to be identified. If the multi-bit number derived from the scanning is the same as any of the reference multi-bit numbers, a correlation count for that particular denomination is incremented. This process is repeated for the whole area of the note and, on completion, the correlation counts for the different denominations are compared. Provided the ratio of the largest correlation count to the next highest correlation count is 1.28 or greater and the largest correlation count is at least 28, the note is identified, as shown by an indicator 36. <IMAGE>

Patent GB-2059338-A (GB)
Title: A saw
IPC: B23D59/00
Filed: 1980-09-17
Abstract: A rotatable portable saw has a saw blade 2 which is pivotally mounted with respect to plate 15 so that the position of the blade relative to the plate 15 can be altered to alter the depth of cut. In a modified form the saw blade can be angled slightly to the direction of traverse of the saw so that the width of the cut can be made slightly greater than the width of the blade. In use the saw is traversed across a workpiece with the blade positioned to produce a scribing cut in the surface of the workpiece and then traversed back across the workpiece, after lowering the blade position relative to the workpiece, so that the workpiece is cut right through. In this way, for a given directional rotation of the blade, the blade can be made always to approach the surface being cut so that splintering of the workpiece is substantially reduced or eliminated. With the modified form of saw the blade is angled so that the scribing cut is made slightly wider than the saw blade and the blade is realigned at the end of the first traverse with the direction of traverse so that on the reverse traverse the saw blade emerges in the wider cut reducing still further any chance of splintering. <IMAGE>

Title: A central heating system having a circulating heating medium
IPC: F24D19/10
Filed: 1980-10-24
Abstract: A central heating circuit comprises a plurality of parallel-connected heat consumer parts 16 of the circuit supplied with heating medium from a common heat source 10, the heat energy consumed by each said part being measurable separately. In each said part is a device 42 which maintains constant the total flow- through-dependent resistance of the part irrespective of the operating state of the relevant radiators 18. An integrator 48 in each said part measures the temperature difference between the inlet 24 and the outlet 30 of the part and integrates it against time, whereby the proportions of the total heat consumption consumed by the individual parts can be compared. The forward-flow and return-flow lines 21, 32 leading respectively to and from the heat source 10 and said parts (e.g. via a mixer 12), are dimensioned (e.g. as to length) and constructed such that irrespective of the total quantity of circulating medium (e.g. water) the same throughput prevails between the forward-flow connection 24 and the return-flow connection 30 at all of the said parts 16 in the circuit. <IMAGE>

Title: Tube rolling
IPC: B21J5/06
Filed: 1981-06-09
Abstract: A small flange (4) is initially formed on the end of a tube to be rolled, the tube then being mounted on a mandrel rod 2 which is pushed through successive roll passes.The wall thickness of the blank (1) reduced in at least three passes, the reduction in the first two passes being 40-60% less than in the third pass. The rod (2) and blank (1) is moved relatively slowly into the first pass (6) minimizing the motive force to be sustained by the flange (4), and accelerated to the third pass (8). The wastage at the flanged end of the blank is further reduced by a part thereof being rolled onto the rod (2) in the reducing passes (6, 7, 8). <IMAGE>
Patent GB-2080224-A (GB)
Title: Air cushion vehicle
IPC: B60V1/11
Filed: 1981-07-06
Abstract: An air cushion vehicle tends to roll outwardly in a turn and, on entering a high speed turn, to pitch bow-down. This is counteracted by dividing at least the rear boundary part of the air cushion area into two laterally disposed cushion compartments 12, 14 and providing means for controlling the inflation pressure of two inflatable skirt walls 19, 20 extending across the rear boundary parts of these cushion compartments. By controlling the inflation pressure of the inflatable skirt walls their effectiveness as cushion seals may be selectively adjusted so as to vent air from the cushion compartment which is on the inside of the turn and thereby produce a shift in the centre of pressure of the vehicle air cushion towards the outside of the turn which counteracts the tendency to roll outwardly. By simultaneously venting air from both cushion compartments a tendency for the vehicle to pitch bow-down is counteracted. The inflation pressure of the skirt walls is controlled by valves 28 in the air supply. <IMAGE>
