Title: Improvements in and relating to perforated record readers
Filed: 1961-08-11
Abstract: 965, 701. Sensing perforated record tapes. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 11, 1961 [Aug. 25, 1960; Feb. 7, 1961], No. 29021/61. Heading G4M. Record tape sensing apparatus consists of means for positioning sections of the tape in turn round the arc of a circle within which a group of photo-cells is adapted to rotate so as to sense the rows of holes rapidly in turn. The tape is drawn from reel 1 to reel 2 and is positioned around a cylinder 7 by sprocket rollers 68 70 driven by a one-revolution clutch 41 through gearing 62 arranged to move a completely new length of tape into the sensing position for each operation of the clutch 41. The cylinder 7 is driven from a source 20 and rotates relative to the tape which is loosely supported on an air film. A circular lamp 8 surrounds the arc of tape on the cylinder. Inside the cylinder is a group of five light guides 21 Fig. 2 spaced at the five bit positions of the tape. A photo-cell 9 is connected to each guide and a cable 23 carries the outputs to slip rings having the usual brushes. The outputs on leads 24 Fig. 1 are amplified at 11, passed through five contacts of a relay at 12, re-coded at 13 and applied to utilization equipment 10 such as a computor having a storage drum 10a rotating with the sensing cylinder 7. A demand signal from the computor energizes the one-revolution clutch 41 to advance the next section of tape to the cylinder 7. At a certain point in the rotation of the cylinder contacts close. If a press-button contact is closed at this time the relay 12 is energized to connect the output to the computor. At the next demand signal from the computor the relay is de-energized and the tape fed to the next section. In the form of Fig. 6 the tape is fed by sprocket pins on a cylinder 101 inside which are a series of light guides 107 concentrating the light from the tape holes at an inner cylinder 103. This carries the five photo-cells which are connected through slip rings as before. The tape is advanced by a motor 128 having a gearwheel 130 engaging a toothed ring 131. The computor store 106 rotates with the cylinder 101. Instead of light guides 107 there may be simple radial holes in an opaque cylinder.

Title: Improvements in or relating to apparatus for optically gauging profiles
Inventor: DIETRICH CORNELIUS FRANK
IPC: G02B21/00
Filed: 1949-11-15
Abstract: 694,950. Optical gauging-apparatus. OPTICAL MEASURING TOOLS, Ltd. Nov. 10, 1950 [Nov. 15, 1949], No. 29259/49. Addition to 652,695. Class 106 (ii). Apparatus according to the parent Specification arranged to give a stationary image of the index is modified in that the index is formed directly on the screen. Feelers 12, 13, with ball-tips 14, 15 and lenses 17, 18 are so mounted on a carriage 16, which can move in any horizontal direction but cannot turn angularly, that, when the carriage is so moved that one of the ball-tips 14, 15 traverses the contour of a stationary gas-turbine blade 11, the corresponding lens 17, 18 describes an equivalent path. A stationary master profile 19 is marked on a transparent graticule 20 arranged in front of a collimating lens 21 above a mirror 22 which deflects light from a source 23 through the graticule 20 and lens 17 or 18 to produce an image 40 of the part of the profile 19 corresponding to the part of the blade 11 being traversed by a feeler 12, 13 on a screen 24 conveniently placed by using mirrors 25, 26, 27. An index 30 in the form of three concentric rings corresponding to permissible maximum, zero and minimum tolerance is depicted on the screen 24 by engraving, photographically or otherwise, a shutter 31 pivoted on the carriage 16 obturates one of the lenses 17, 18 being actuated by a solenoid 33 according to which feeler 12, 13 is in action. In order to use a stationary index the master profile 1 19 must be (1+-) times the corresponding M contour of the blade 11 where M is the magnifying power of the lens 17, 18. If r is the radius of a ball-tip 14, 15 the middle ring of the index 30 must be of radius (M+1)r. Thus, if it is desired to change the magnification, the lens 17, 18, master profile 19 and index 30 must all be changed. However, if collimating lenses are used in place of the lens 17, 18 and a lens 28 of large diameter is introduced, the master profile will be drawn the same size as the corresponding contour of the blade 11 and the magnification may be changed by changing the collimating lenses when it will only be necessary to change the size of the index 30 and to adjust the distance between the graticule 20 and the collimating lenses.

Title: Improvements in or relating to photographic shutters
IPC: G03B9/10
Filed: 1955-10-21
Abstract: 776,125. Photographic shutters. KODAK, Ltd. Oct. 21, 1955 [Oct. 25, 1954], No. 30098/55. Class 98(1) In a photographic shutter having a pivoted shutter blade and a pivoted cover plate normally covering the exposure aperture of the shutter, the shutter blade has a latch element holding the cover plate in its rest position and during the initial part of the release operation of the shutter trigger as a spring connecting the trigger with the cover plate becomes tensioned, further operation of the trigger effecting release of the latch to permit the cover plate to uncover the exposure aperture under the action of the tensioned spring, the cover plate during such movement operating a spring connecting it with the shutter blade so as to move the latter from a position where it uncovers the exposure aperture into a position where it covers such aperture. As shown in Fig. 1, the shutter comprises a cover plate 13, pivoted at 14 and a shutter blade 24 which has an elongated slot 28 and which is pivoted on a stud 23 under a raised portion 22 of the cover plate 13. The plate 13 and the blade 24 are connected by a spring 30 anchored between the lugs 31, 32 and biasing the blade 24 to the 'rest position wherein the tail 27 engages the abutment 47. The trigger plate 3 is conected by the pin 7 to a release plunger 4, and the plate 3 and plunger 4 are normally urged to the rest position shown by a spring 11. The arm 5 of the plate 3 engages the lug 32 to move the plate 13 over the exposure aperture 2. A spring 16 connects the lug 15, which has a nose 19, on the plate 13 to the lug 18 on the plate 3, the nose 19 being engaged by the lug 25 on the blade 24. On depression of the plunger 4, the spring 16 is first tensioned as the lug 25 holds the plate 13 in rest position, but then the arm 6 of the plate 3 strikes the lug 26 on the blade 24 and rocks it slightly anti-clockwise about stud 23 to disengage the lug 25 from the nose 19. Since the arm 5 has moved away from the lug 32, the spring 16 rotates the plate 13 anti-clockwise clear of the exposure aperture 2 until a shoulder 20 on the plate 13 engages the fixed' abutment 21. As the lug 32 passes across the pivotal centre of the blade 24, the spring 30 is tensioned and the blade 24 moves anticlockwise to cover the aperture 2. When the plunger 4 is released, the plate 3 returns to rest position and the arm 5 rocks the plate 13 back to rest position to coverthe aperture 2, and the tensioning of the spring 30 produced rotates the blade 24 back to rest position, the lug 25 re-engaging the nose 19. The plunger 4 and plate 3 may be made in one piece. As the plate 13 swings from rest to uncover the exposure aperture, a cam 50 thereon engages a spring arm to connect two connectors to close the circuit through a flash bulb.
