Title: Improvements in or relating to electrical voting systems
IPC: G07C13/00
Filed: 1963-12-19
Abstract: 1,074,540. Voting apparatus. VALMONT CORPORATION. Dec.19, 1963 [Dec. 31, 1962], No. 50216/63. Heading G4T. An electrical voting apparatus consists of voting panels each having push-buttons for vote selections, and lamps which light up to indicate which choice or choices have been made, and remain lit until the votes are sent to a counter associated with the panels and are then automatically extinguished. As described, a central computer EC scans a plurality of outlying districts via telephone lines TL, each of which includes a vote counter PS and a plurality of voting panels VP controlled from a control desk JD. Each voter is allotted to a voting booth VB and a start switch on the control desk is energized to supply power to the voting panel in that booth. The voting panel includes a plurality of sets of three switches D1, R1, O1, each of which may be closed by depression of a corresponding push-button. Each set of three buttons is for selection of a candidate for a particular office. When the start switch is closed at the control desk a plurality of sets of transistor pairs T 1 -T 2 , T 3 -T 4 , T 5 -T 6  are switched from the state of both non-conducting to one T 1 , T 3 , T 5  conducting and the other T 2 , T 4 , T 6  non-conducting. Each of the pushbutton switches is associated with a corresponding transistor pair so that when the button is depressed the base of conducting transistor is earthed and, since all transistors are of NPN type, thus switched off. The other transistor of the pair is switched to conduction illuminating an associated lamp L1, L2, L3 so that the voter can see which candidate he has voted for. He may change his vote by depressing any other one of the switches D 1 , R 1 , O 1 , in which ease the corresponding transistor pair is switched and the originally switched pair reverted to their original state. An erase pushbutton EP switches back all three transistor pairs associated with the particular office. When the voter is satisfied with all of his selections he closes a tally switch TPS to send his selections to the district counter. In case the voter wishes to nominate an unspecified candidate for a particular office a tally roll 237 is provided. This roll is advanced by one step for each vote taken and if it is not allowable to select an unspecified candidate the roll is punched over the inserted name to cancel the vote. The voting panel is finally reset to prepare for the next voter.

Title: Magnetoresistive sensing of cylindrical magnetic domains
IPC: G11C19/08
Filed: 1972-11-02
Abstract: 1370079 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 2 Nov 1972 [20 Dec 1971] 50456/72 Heading H3B A magneto resistive sensing arrangement for cylindrical domains propagated in a garnet or orthoferrite magnetic sheet 12, Fig. 1, has its change of resistance enhanced by expanding each domain as it reaches a read out region 35 to a size approximately equal to the length of the magnetoresistive element 26. The domains may be propagated by the combination of an in-plane rotating magnetic field H and a T and I bar overlay pattern of soft magnetic material such as permalloy. When a domain moves into region 35 it becomes enlarged due to the elongate and stepped shape of a magnetic overlay portion 24, this enlargement being enhanced by a current pulse + I s  passed in an appropriate sense through the magnetoresistive sensing element 26 from a generator 30. Change of resistance of the sensing element due to rotation of its vector is determined by a detecting means 34. Due to the length of overlay portion 24 the domain is destroyed when it is moved further along the portion by the rotating field, this domain erasure being aided by a reversed direction current pulse -I s  applied through the element 26 from the generator 30. In a modification, Fig. 4 (not shown), the overlay portion consists of two spaced and parallel parts. The domains may alternatively be propagated by the use of sequentially energized conductors 42, 44 each having a small deposit of permalloy 42a, 44a. The domains move in succession through positions 1, 2, 3 and 4, a domain in position 3 being enlarged while a domain at position 4 is destroyed. A domain is moved into position 3 and enlarged at the same time by passing a current +I 0  through a conductive loop 52 supporting a permalloy strip 54. The enlarged domain changes the resistance of an adjacent magneto-resistive element 62 which is detected by a means 70 connected across a pulse generator 66. A domain is moved from position 3 to position 4 by passing a reverse current -I 0  through the loop 52 and it is held in that position by permalloy pieces 56 until it collapses. The magnetic sheet may be composed of Eu 0À7 - Y 2À3 Fe 3À8 Ga 1À2 O 12  having a layer of SiO 2 , and a permalloy layer providing both the overlay pattern and the magnetoresistive sensing element, the layers being deposited by evaporation or sputtering.

Abstract: 1366021 Controlling tension of endless conveyer chains JERVIS B WEBB CO 10 Nov 1972 [30 Nov 1971] 51955/72 Heading B8A The rate of take-up of a conveyer chain is limited by the action of an hydraulic control valve 62. As shown, an endless conveyer chain guided by rails 27, passes around a return bend section 40 of the rails 27, which is mounted on a frame 34 movable relative to the fixed framework of the conveyer. The frame 34 is urged in a direction tending to extend the conveyer chain by pressure fluid in a cylinder 48 acting on a piston 50. The rod 52 of the piston 50 is connected to a piston 46 in a cylinder 44. Each side of the piston 46 is connected to a hydraulic circuit 64 having the control valve 62 (a flow restriction valve) and a one-way valve 63 in series. A further valve 70 in series in the circuit 64 is normally open but is closed by solenoid action in the event of stoppage of the drive motor 15. A manual valve 76 can be set to bypass the circuit 64, and spring-loaded valve 74 can override the one-way action of the valve 63 in response to a very heavy load. In a modification (Fig. 4, not shown), the cylinders 44 and 48 are replaced by a single piston and cylinder unit and a separate hydropneumatic unit.

Filed: 1971-11-12
Abstract: 1354158 Photographic processes using hydrogen peroxide addition compounds AGFAGEVAERT AG 12 Nov 1971 [17 Nov 1970] 52592/71 Heading G2C A photographic process for the production of visible images comprises imagewise exposing of a photo-sensitive layer to produce in the layer an imagewise distribution of a substance which catalytically decompose hydrogen peroxide, treating the layer with an adduct of hydrogen peroxide and an organic compound from which hydrogen peroxide is generated on decomposition, and there producing a visible image either physically in the form of vesicles (the layer containing a film-forming binder) or chemically by using the oxygen formed by the decomposition of the hydrogen peroxide for a colour-forming oxidation reaction. Preferably heat is required to decompose the adduct. The light-sensitive layer may be silver halide optionally with a coupler (as in Specifications 1196200 and 1268126), a heavy metal complex salt as in Specification 1329444, a protein as in Specification 1332692 or an organic compound generating iodine as in Specification 1307559. The specified adduct is a 1:1 adduct of urea and hydrogen peroxide but adducts with amides, hydrazides or aliphatic polyhydric alcohols may be used. In Example 3, a silver halide emulsion is imagewise exposed and developed, treated with the adduct and then with a solution containing pyrocatechol and N, N-diethyl p-phenylene diamine to produce a dye image. In Example 4 silver halide emulsion containing a cyan coupler is exposed and developed to produce a silver image, treated with the adduct and then with a colour developer to produce a cyan image on the silver image. Alternatively, a mixture of ammonium ferric citrate, ammonium ferric oxalate and potassium ferricyanide may be used to produce a faint blue image which is amplified by the peroxide treatment.

Abstract: 1,145,397. Inspecting glass photo-electrically. FORD MOTOR CO. Ltd. Nov. 22, 1967 [Dec. 13, 1966], No.53075/67. Heading G1A. [Also in Division G2] Wedge defects in glass are measured by directing a beam of parallel light through the glass, reflecting it back through the glass and focusing the beam on a beam divider which divides the beam between two photo-cells in a proportion which depends upon the deflection of the beam by wedge defects in the glass. Light from a pinhole 19 illuminated by an incandescent or discharge lamp or a laser 13 is collimated by a lens 25 and reflected by a mirror 27, of smaller size than lens 25 to pass twice, through the glas sheet 11 under test. The beam, rendered converging by lens 25 is then split by a prism arrangement 29 and passes to identical systems for measuring horizontal and vertical wedge. The "horizontal" portion of the beam falls on a roof mirror 35 which divides the beam equally between photo-cells 37, 39 when the glass 11 has no horizontal wedge. Photo-cells 37, 39 are in a bridge circuit and any imbalance due to wedge actuates a compensating glass block 33 to remove the imbalance. The position of the block 33 indicates the degree of horizontal wedge and the indication may be recorded in correlation with the movement of the glass through the inspection point. When a photodetector 47 detects the absence of glass at the inspection, the output of the bridge circuit adjusts a zero compensator 31 to calibrate the apparatus. The beam splitter 29 and dividers may be replaced by a square pyramid reflector.
