Title: Means for controlling the intensity of a beam of light in accordance with electrical variations, for use, for example, in recording sounds
IPC: G11B7/00
Filed: 1927-12-09
Abstract: 307,539. Whitaker, A., Browne, C. O., and Gramophone Co., Ltd. Dec. 9, 1927. Light-valves.-Relates to means for controlling the intensity of a beam of light in accordance with electrical variations, applicable for use in recording sound, wherein the variations are applied to stress a body through which the beam after polarization is directed. The invention consists in selecting the light path so as to avoid dispersion when a light source comprising two or more wave lengths is employed. In one arrangement, the beam from a source S passes through a lens C and polarizer P and is reflected by a prism R through a quartz crystal Q on to a mirror M which reflects it back through the crystal and through the analyser A. The electrical variations are applied to conductors at opposite sides of the crystal Q which acts on the reflected beam to correct any dispersion caused in its first passage, and the beam if influenced by sound may make a record on a sensitized travelling strip B. In a modification, the beam is passed in one direction only through a crystal whose length is so selected that the various wave lengths of light in the source are rotated by the crystal through angles which vary from one another by 180‹ or a multiple thereof.

Title: Improvements in electro-mechanical transducer systems
IPC: G06G7/22
Filed: 1957-10-28
Abstract: 878,945. Measuring electrically. SANGAMO WESTON Ltd. (Weston Electrical Instrument Corporation). Oct. 28, 1957, No. 33597/57. Class 40 (1). [Also in Group XXXVI] An electro-mechanical transducer comprises a moving coil device in which an alternating component is added to the field due to a permanent magnet. The transducer may be used in a system for producing a D.C. signal representative of the angular displacement of a shaft from a datum position (e.g. in an analogue computer system), and in a system for producing an angular displacement of a shaft in correspondence with an input D.C., the shaft being used to drive, e.g. the stylus or drum of a recording mechanism. Displacement to D.C. system. Fig. 1. Rotation of a shaft 2 is transmitted via a resilient coupling 13 to a coil 9 pivoted in the flux-gap of a permanent magnet 6 and a cylindrical iron yoke 8, the yoke carrying the secondary windings 14 of a transformer 16 which is energized from a source 18. Movement from its null position causes the coil 9 to link the alternating component of flux, the resulting A.C. signal being fed, via a transformer 24 to an amplifier 29, a phase sensitive rectifier 30, and a filter 33, the output of which is supplied to the coil 9 to return it substantially to its null position. An ammeter 4 indicates the magnitude and polarity of the feedback current, which are representative of the degree and direction of displacement of the shaft 2. D.C. to displacement system. Fig. 3. A D.C. signal applied to terminals 31 rotates the coil 9 in the pulsating field, and the A.C. signal thereby produced is amplified at 44 and supplies to the armature of a motor 43, the field coils of which are fed with A.C. The motor 43 rotates shaft 2 to transmit a restoring torque to the coil 9, the useful output being taken from shaft 2, gear train 47, or motor shaft 46. Recording device.-As shown, Fig. 3, the displacement of motor shaft 46 moves a cord 50 which controls the position of a pen or stylus 49 on a chart driven at a constant speed by a synchronous motor 48. Transducer construction. Fig. 5. The shaft 2 which is supported on bearings (not shown) in a hub 52, is connected to the rotatable coil 9 via a plastic disc 53, a pin 54 eccentrically mounted thereon, spring 13, and a connecting arm 59. Arm 59 is fastened to a stub shaft 61 which, with a second stub shaft 62, pivotally supports the coil 9 between bearing members 66 and 68, themselves supported by members 67, 69, which are secured to, but spaced from, the cylindrical yoke 8. The permanent magnet 6 is secured within the yoke 8 by a screw (not shown). The stub shaft 62 is fastened to a temperature-compensating spring 63 which also acts as a current lead to the coil 9; the other current lead comprises a spring 71, pin 54, spring 13 and arm 59. The transformer 16 is fastened by posts 78 to an end plate 74 on the yoke, the secondary windings 14, which comprise 4 rigid turns of wire, being held by non- magnetic plates 79 secured to the yoke.

Title: Sewing machine for making a zig-zag or back stitch
IPC: D05B73/12
Filed: 1927-12-12
Abstract: 294,425. Mundlos, R. Dec. 12, 1927. Zig-zag feed; continuously-reversing feed; button-attaching machines. - The feed-bar is given a lateral movement, in addition to the usual to- and-fro and up-and-down movements, to make a zig-zag stitch by a link connected to a rocking lever 10 operated by a cam 7 rotated by the main shaft 1 by pinions 4, 6. In the form shown in Fig. 1, the feed-bar 19 is slidably mounted on a shaft 16 supported on and parallel to the feed rocking shaft 18 by arms 17. Rigid with the feed-bar is a fork 15 engaging a pin 14 on a slide 12 which is reciprocated to give the feed-dog 20 its lateral movement by the link 11 connected to the rocker 10. The amount of the lateral movement is determined by the position of the link 11 along the slot in the rocker 10. In the form shown in Fig. 4, the slide 12 is suppressed, the rocker 10 being directly connected to the feedbar shaft 16 by a link 35 having a head 35<b> connected to the part 35<a> which can rotate relatively to the part 35 to permit rocking of the arm 17. The arms 17 rigid with the shaft 18, may be replaced by a pair of spring pressed pivoted bearings 36, Fig. 5. For attaching buttons, a clamp 52, 54, Fig. 6, is secured to the feed-dog 20 to hold the button 55 m place. The presser-foot 57 engages under a lip 59 on the part 58 of the clamp, so that raising the presser-foot releases the button. The machine may be used for cut-work embroidery by providing a telescopic link 11, 11<a>, Fig. 2, with a lug 27 engaging a frame 25 on the slider 12 so that when the sewing round the edge of the perforation is completed, the feed-dog 20 and frame 12 can be moved to the extreme outer point by the levers 28, 29 and 30, to allow the thread to be drawn off at the outer edge of the stitching. The bend 26 prevents the frame from being moved too far when the link 11 is near the end of the slot in the lever 10, as shown by the broken line to make a small zig-zag stitch.
