Abstract: 1,257,921. Diagnostic scanning apparatus. P. J. GILLESPIE. 2 July, 1969 [5 April, 1968], No. 16414/68. Heading H4F. In a scanning arrangement in which a series of parallel lines are scanned in alternate directions (e.g. diagnostic apparatus in which a scintillation counter produces pulses at a rate dependent on the concentration of radioactive material in a patient), and in which a printer synchronously scans and prints out on a sheet secured to a table the output from the scanner with a time delay (e.g. corresponding to .integration time for determining the pulse rate of the scintillation counter), the relative positions of the printer and the table are altered between successive lines to reduce the effect of this delay on the printed sheet. This is effected by moving the printer or the table parallel to the scanning lines between successive scans. Preferably the table is moved at the end of each line by one or two solenoids actuated by a microswitch which is operated by the scanning movement of the printer, the amount of movement of the table being set by adjusting two cams which co-operate with a stop mounted on a frame in which the table is .slidable. The printer includes a multi-coloured ribbon and produces different coloured marks on the -sheet (paper) in accordance with the concentration of radioactive material detected by the scanner.

Abstract: 1323411 Cutting sheets M FISH & SON (1942) Ltd 9 Julv 1970 [9 April 1969] 18265/69 Divided out of 1323412 Heading B4B Apparatus for cutting sheet material comprises a guillotine having two blades 1, 2, clamping members 6, 7 adjacent the guillotine means 8 for gripping an edge of a sheet and means 13-16 for moving the gripping means 8 to feed the sheet to the guillotine. Suction means 4 may be provided for supplying sheets 5 from a stack, and control means is provided for effecting the following steps: actuating the gripping means 8 to feed a sheet, actuating the clamping members 6, 7 to locate the sheet for cutting, actuating the guillotine to produce a straight cut edge, releasing the clamping members 6, 7 and actuating the gripping means 8 to position the sheet for a second cutting stroke, re-engaging the clamping members 6, 7, and actuating the guillotine to produce a second cut edge parallel to the first. Alternatively (not shown), the gripping means may act directly to feed web material by unwinding a roll. Preferably, a second similar cutting apparatus, Fig. 1 (not shown), operated by the same control means receives the cut sheets from the first at right angles to the feed direction of the gripping means 8, a second guillotine (1A), (2A) being operable to trim the remaining edges of the sheet, producing an accurate rectangular blank. In operation, a sheet from the stack 5 is engaged by solenoidactuated suckers of the suction means 4, and raised under control of a solenoid S2. A bar 13 supporting the gripping means 8 is advanced on rails 14 by piston/cylinder means 16 into contact with a buffer stop BS1, whereupon a solenoid S5 actuates gripping members 17 to engage the sheet, the suction of the means 4 is discontinued and a further buffer stop BS4 is raised. The bar 13 is then retracted, the sheet being drawn between the blades 1, 2 and clamping members 6, 7, until engagement of the stop BS4 actuates the clamping members, releases the gripping members 17 and actuates the movable upper blade 2 to trim the edge of the sheet. The sheet is then re-engaged by the members 17, the clamping members 6, 7 disengaging, and the bar 13 is retracted to a position governed by a buffer stop BS3, mounted on a carrier member 20 for adjustment by means of a screw 21, the clamping members 6, 7 in addition to a further clamping device 12, and the guillotine then acting to trim the second edge. The sheet is then fed towards the blades (1A), (1B) of the second cutting apparatus. In the event of the sheet 5 being too short for its second edge to reach the guillotine of the first apparatus for the second cutting stroke, it is ejected into a recess 24 by lines 23 of a bar 22, lowered into contact with the sheet 5. The short sheet is sensed by a photocell adjacent the guillotine if a light beam is not interrupted by the sheet.
