Title: Improvements in or relating to indicating and/or recording apparatus
IPC: G01D7/06
Filed: 1937-11-17
Abstract: 505,847. Oscillographs. SIEMENS & HALSKE AKT.-GES. Nov. 17, 1937, No. 31646. Convention date, Nov. 26, 1936. [Class 37] [Also in Group XIX] In indicating or recording apparatus dealing with two or more variables and comprising two or more measuring instruments each controlling a mirror, a light beam passing from a source to the first mirror, thence to the second and then to the indicating or recording point, an optical system is provided between the two mirrors whereby the axis of the beam reflected from the first mirror is always maintained incident at the same point on the second mirror in spite of the movements of the first mirror. In one form, Fig. 2, light from a source 1 is reflected by a mirror 2 rotated by one measuring instrument, passes through a convex lens 5 to a mirror 3 rotated by a second measuring instrument about an axis at right-angles to the axis of rotation of mirror 2, and is then reflected on to a screen 4. The lens 5 is so positioned that, in spite of the movements of the first mirror 2, the beam always meets the second mirror 3 at the same point P. In another form, Fig. 4, the light path is represented diagrammatically as a straight line, but in fact the light passes from the source 1, is reflected by the measuring- instrument mirrors 2, 3 and passes to the screen 4. The lens 5 between the mirrors 2, 3 has its focal points at F', F<SP>2</SP> and another lens 8' projects an image of a diaphragm 7 at a point 7<SP>11</SP>. In a further modification, Fig. 6, four oscillograph mirrors 9 ... 12 are used in conjunction with three fixed curved mirrors 14, 14<SP>1</SP>, 14<SP>11</SP> to deflect a light beam on to a recording surface 13. The curved mirrors 14, 14<SP>1</SP>, 14<SP>11</SP> are so arranged that the light beam is always incident at the same point on the mirrors 9 ... 12. The three oscillographs may be controlled by wattmeters in the three phases respectively of a three-phase electrical system. In other arrangements : (1) four mirrors are used, two rotating about axes at right-angles to the axes of rotation of the other two, a lens system being provided between each pair of mirrors, each mirror being operated by a separate measuring instrument; (2) three light beams are reflected by a single measuring- instrument mirror and then each beam passes through a separate lens system on to a separate mirror actuated by another measuring instrument and thence on to a screen.

Title: Improvements in or relating to document feeding and positioning apparatus
Inventor: HEWITT ALAN ROBERT
IPC: B41J11/46
Filed: 1959-09-17
Abstract: 915,561. Selective printing. INTERNATIONAL COMPUTERS & TABULATORS Ltd. Sept. 2, 1960 [Sept. 17, 1959], No. 31714/59. Class 100 (4). Special platen rotation.-Documents or continuous stationery I are fed to particular line positions for printing by feeding apparatus controlled by a multiple-stage shifting register 7 into which a pattern of arresting signals are entered by a potential 15, key 14, sockets 12 and various plug connections 11. This action puts each stage 8 of the register 8 in its set position. As shown in Fig. 1, connections are made, reading right to left, to the 6th, 7th, 8th, 10th and 12th positions which correspond to the lines in which printing is to occur, and as the stationery is fed the set positions are stepped along the register from left to right by pulses received on line 21 from, as shown, a photoelectric generator 17-20, or alternatively a phonic or waveform generator. When the signals reach the end register 80, e.g. when the first set register (6th) has been stepped six times and the platen has consequently fed the stationery six lines, a pulse is sent along line 23 to amplifier 24 and a solenoid in a feed control mechanism operates a pawl to stop a motor feed to the platen. At the same time a signal is sent to the Printing Control to effect printing. The manual entry of arresting signals into the register 8 done by the key 14 may be effected, by photo-electric means 35, 36. Further photo-electric means 39, 40 may enter arresting signals for a second part of the stationery if the number of lines on each form length is greater than the number of stages in the shift register. If there are identical number of lines and stages the entry may be automatic by recirculating the entry by means of connection 22. In a further embodiment, Fig. 3, not shown, there is one sixteen stage register for arranging for line selection at the head of a sheet and a second register for the foot of the sheet. The pulses from the generator over line 21 is simultaneously applied to both registers and to a binary counter 67 and a second counter 53. Counter 67 has four binary counting stages and by producing an output signal on line 54 after every sixteenth pulse ensures by means of the second counter 53 which is a two stage, scale of four counter and AND gates 55, 56 that the sheet is arrested only at the appropriate section of the sheet, i.e. the first and fourth groups of sixteen lines.
