Title: Record reading apparatus
IPC: G06K7/02
Filed: 1960-11-18
Abstract: 962, 663. Sensing statistical records. SPERRY GYROSCOPE CO. OF CANADA Ltd. Nov. 18, 1960 [Dec. 2, 1959], No. 39735/60. Heading G4M. In a pneumatic sensing device for a record tape the tape 12 Fig. 1 passes over a body 14 having an array of sensing ports on its upper face, the lower surfaces being cut away obliquely as shown in Fig. 8 to increase the spacing between the ends of bores 110 and facilitate connection of flexible pipes by plates 116. The tape is held down during sensing by an upper plate 56 also formed with through bores at each perforation position. Each pipe 20 is connected to a separate pressure capsule 18 which is continually supplied with compressed air through a metering orifice 134. If the pipe is connected to a bore in block 14 which is blocked by an unperforated part of the tape the pressure builds up inside the capsule 18 and the flexible diaphragm 142 expands to open or close a switch 22. If the tape is perforated at the corresponding position the air passes out through the plate 56 and there is no expansion of the diaphragm. At the end of the sensing operation the tape is fed to bring the next frame into the sensing station. For this purpose the sprocket wheel 30 is driven by energization of clutch 38, a Geneva gear being interposed to ensure that the tape is correctly indexed. A cam-shaft 80 rotates to raise the clamping plate 56 and to close switch 78 to operate the clutch 38. The signals from switches 22 are recoded in a network 24 and applied through contacts of relay R1 to amplifiers 25. The output may be used to control a tool through a servomotor system while the tape is being advanced the relay R1 is energized to open the output circuits from the network 24.

Filed: 1971-08-26
Abstract: 1381277 Bi-metallic temperature responsive elements ROLLS-ROYCE (1971) Ltd 29 Aug 1972 [26 Aug 1971] 40190/71 Heading G1D [Also in Divisions Fl and F2] A gas turbine seal includes a bi-metallic motor device which causes axial movement of a circular sealing surface with change in temperature. In one arrangement, Fig.8, the motor device comprises rings 40, 41 secured together by part-spiral members 42. Since the latter have a different coefficient of expansion to one or other of rings 40, 41, heating of the assembly causes rotation of ring 41 relative to fixed ring 40. Inter-engaging helical splines (45), Fig.7 (not shown) cause the rotation to be accompanied by corresponding axial movement of ring 41 to maintain the sealing clearances. Wedge shaped fillets (44), Fig.10 (not shown) fill the spaces left by part-spiral members 42. In a modification, Fig.4, the motor device comprises a centre spine 24 secured on both sides to shims 27 and bi-metallic stacks 26, secured in turn to fixed end-plates 25. Each stack comprises laminae, e.g. of higher and lower specified nickel content, having different coefficients of expansion and secured together at alternate ends in the manner shown by laminae 21, 22 in Fig.3. Change in temperature causes each stack 26 to deform from its normal rectangular shape into a parallelogram causing centre spine 24 and an attached sealing surface to move to the left or right to maintain the sealing clearances.

Abstract: 1,169,685. Making tubes. P.U. POULSEN. 23 Aug., 1968 [1 Sept., 1967], No. 40534/68. Heading F2P. In a machine in which pipe-making material, e.g. thermosetting glass-reinforced plastics, is continuously applied to a mandrel 1 whose outer surface 3 consists of an endless steel strip 3a wound edge-to-edge, the strip is enabled to move axially along and off the end of the mandrel to clear the tube by means of balls 16 running on guide rails 15. As the mandrel rotates on bearings 4, 5, the steel strip is first wound on to the mandrel from rollers 9; it progresses from left to right along the mandrel; and finally leaves it over rollers 7 to return over reel 8 and through the hollow core of the mandrel to the rollers 9. The steel strip winds on to and off from supports 6 which each have an endless belt of balls 10 spaced by a ball-carrier 10b. Because of the inclination of the rails 15, the balls are gripped against any but axial rotation, so that they transmit the rotation of the mandrel to the strip without impeding its axial movement. The tube is formed continuously and is cut off as desired.

Abstract: 1393437 Band saw machine M J PEDI 6 Sept 1972 [10 Sept 1971] 41215/72 Heading B5L Apparatus for repeatedly feeding a unit of material, e.g. frozen fish, to a saw tool 14 for cutting slices from the units comprises unittransporting feed means movable between a start position in which the saw tool is at one side of the unit to a finish position in which the saw tool is beyond the other side of the unit to cut a slice from the unit, and returnable to the start position, and wedging means for introduction into the cut just made between a slice and the rest of the unit to displace the uncut portion away from the slice so that it does not interfere with the saw blade during the return movement to the start position. In the slicing machine described, a block 18, Fig. 1, is fed from a stack 20 on to a horizontally reciprocated table 22 and is urged against a fixed guide fence 40 by a jaw 50. The table 22 is then advanced to feed the block past the saw blade 14 to cut a slice 30, Fig. 2, therefrom. On completion of the cutting, a wedge 24 is advanced vertically into the cut so as to displace the uncut portion 18a of the block together with the jaw 50, so that as the table 22 is returned the portion 18a is clear of the saw blade. After return, the jaw 50 is again advanced to reclamp the block and the process is repeated until the uncut portion of the block is less that a predetermined thickness. This condition is detected by a switch 92 having an arm 94 moved by a member 96 on the jaw 50, and as a consequence a retaining jaw 32 is caused to clamp both the slice and the uncut portion against the fence 40 so that the table 22 returns empty ready to receive a further block from the stack. When the new block advances, the jaw 32 is released and the slice and uncut portion are separated, as they are pushed forward by the new block, by tines 109. A control unit 48, Fig. 1, operated by various limit switches controls pneumatic piston and cylinder devices operating the table 22, jaw 50 jaw 32, and a pusher for feeding new blocks from the stack 20. Means is provided for stopping the feed means should the saw blade break.
