Title: Projecting optical images
IPC: G02F1/29
Filed: 1965-05-10
Abstract: 1,057,963. Photographic type-composing. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 10, 1965 [May 25, 1964], No. 19564/65. Heading B6W. [Also in Divisions G4 and H4] Apparatus for projecting optical images of information stored in a transparent Lippmann film 10 having a number of image areas 12 each responsive to radiation of different predetermined frequencies comprises a light source 16 which directs a beam of light at a selected frequency (filter 22) and linearly polarized (polarizer 20) through a beam splitter 26 and a plurality of electro-optic devices formed by electrooptic crystal 30 and transparent electrodes 32 on opposite sides of the crystal in alignment with each of the areas 12. The information is stored in the film 10 in the form of reflecting layers 14 which may be in the shape of alphabetic or numeric characters and the layers for any one of the characters are spaced from each other distances which are inversely proportional to the frequency of the light which originally effected the depositing of the material forming the layers. When quarter-wave voltage is applied to any one of the electro-optic devices, plane polarized light passing through that device becomes circularly polarized and if the area receiving light from this device contains stored information corresponding to the light frequency, then the circularly polarized light is reflected back through the same electro-optic device and becomes plane polarized at 90 degrees to the original beams polarization direction. The reflected light then passes through the beam splitter, which splits the beam according to polarization, and a light deflector 40 to a photo-sensitive medium 46 for effecting a printing of the information. At each of the electro-optic devices not energized, light passes through them without any change in polarization and is reflected back to the beam splitter polarized in a plane which causes the light to return over the same path as that of the interrogating beam from source 16. Deflector 40 is such that a light beam entering it at any point is deflected to a common point 42, medium 46 being moved relative to deflector 40 for effecting printing on a line. Filter 22 is adjusted by the operator so that the frequency of the light delivered to the film corresponds to the frequency which caused the formation of the reflecting layers for the character desired. For half-tone reproduction the electrodes 32 are subjected to less than quarter-wave voltage. At any one area on the film there may be a number of different sets of reflecting layers each set being of a different character shape and having the layers within it spaced differently corresponding to different light frequencies. In a second embodiment, Fig. 2, not shown, the film 10 has information stored over its full surface as a picture or page of information and crystal 30 has two electrodes extending over an area equal to that on the film 10 so that the whole picture or page of information is displayed on a photo-sensitive material.

Title: Improvements relating to the mounting of electric arc electrodes
Inventor: HUMPHREYS GEORGE
IPC: H05B7/109
Filed: 1961-05-31
Abstract: 941,895. Electrode clamps. BIRLECEFCO (MELTING) Ltd. May 7, 1962 [May 31, 1961], No. 19677/61. Heading H5H. An electrode clamping arrangement which permits controlled axial displacement of the electrode includes a clamp for holding the electrode against a force tending to produce such displacement, and an electromagnet controlling the clamp and connected to a circuit which includes means for briefly and repeatedly causing the release of the clamp, to permit an incremental displacement of the electrode by the force. Arc electrode 1 is positioned within an axially split sleeve 2, which is itself supported by its flange 2<SP>1</SP> and caused to clamp the electrode by the split cylinder 3, the flanged portions 9 and 11 of which are urged together by compression springs 4. The core and yokes 7 of an electromagnet having a coil 8 are secured to the flange 9, and an armature 10 is secured by tie-rods 12 to flange 11, whereby energization of the magnet causes it to be displaced towards the armature, counteracting the effect of springs 4 and allowing the electrode to slide down within sleeve 2 while energization persists. Operation of switch PB allows capacitor C to discharge through resistor RD, energizing the magnet for a period determined by the circuit time constant. As an alternative to the repeated manual depression of a button PB, the operation of a push-button may initiate, and maintain until released, the operation of an automatic pulse repetition circuit feeding coil 8. Switch S permits continuous energization, to allow removal of the electrode from the clamp. In a modification (Fig. 2, not shown), the electromagnet acts upon a mechanical linkage which actuates the clamp.

Patent GB-610708-A (GB)
Title: Fluid flow meter
IPC: G01F1/24
Filed: 1944-10-18
Abstract: 610,708. Systems for indicating and integrating fluid flow. FISCHER & PORTER CO. Oct. 18, 1944, No. 20196. Convention date, Nov. 25, 1943. [Class 40 (i)] [Also in Groups XXXV and XXXVII] A system for the remote indication of fluid rate-of-flow comprises an A.C. impedance bridge having two transmitter coils wound end to end, coaxially with a metering tube, a float carrying an armature moving up and down in response to variations of rate-of-flow and two receiver coils placed side by side with their armatures connected to the ends of a balanced beam connected to the indicating device so that movement of the float unbalances the bridge, thus varying the current in the receiver coils and causing the beam to tilt and rebalance the bridge. The transmitter coils 27, 28, Fig. 3, are wound round a well 24 extending downwardly from the metering tube 12, the float 22 carrying a soft iron armature 26. Armatures 40, 41, Fig. 5, which move within receiver coils 36, 37 are suspended from opposite ends of beam 44, the ends of which are formed as arcuate segments so that the armatures always hang in the same vertical line. Movement of the float 22 in response to change of rate-offlow changes the relative impedances of coils 27, 28 and therefore the current in receiver coils 36, 37, so that the beam tilts until armatures 40, 41 take up a position within the coils at which the bridge is again balanced. A pen arm connected to the beam records the movement on a continuously rotating chart. Fig. 1 shows apparatus for integrating the fluid flow, including an electrical counter 56 which makes one count every time switch 57 closes. The switch 57 is operated by magnet 58 whenever one of the slots in the iron interceptor wheel 70 comes in line with the switch 57 and magnet 58. Thus the number of counts will be proportional to the rate of rotation of the wheel. Wheel 70 is driven by wheel 73 which is engaged upon upward movement of pawl 75 mounted on arm 76 of actuator 77 which is swept upwards at regular intervals by eccentric 79 driven by motor 55, the amount of movement depending upon its initial position which is governed by calibration cam 82. Tilting of beam 44 controls the angular position of cam 82 and thus alters the speed of wheel 70, the cam being shaped to make the rate of rotation of wheel 70 proportional to the rate of flow indication.
