Title: A reversible electro magnetic indicative counter
Inventor: KILMINSTER SHIRLEY ANTHONY
IPC: G06M1/10
Filed: 1956-04-07
Abstract: 794,228. Counting-apparatus. HADLEY TELEPHONE & SOUND SYSTEMS, Ltd. April 8, 1957 [April 7, 1956], No. 10685/56. Class 106 (1). A reversible electromagnetic counter counts the difference between the number of pulses on two lines and comprises a tape-bearing indicia, the ends of the tape being wound respectively about a spring-biased supply spool and a driven spool, the driven spool being intermittently rotated against the spring bias by an electric motor under the control of a solenoid, and intermittently rotated in the other direction by the supply spool bias under the 'control of a second solenoid, whereby the tape is adapted to indicate the difference between the number of electric impulses received by the two solenoids. A tape 1 bearing indicia 1a is carried at one end by a supply spool (not shown) and at the other end by a driven spool 2 freely mounted on but normally locked to a shaft 4 which is rotatably mounted between bearing plates 5a and 5b. The shaft 4 carries at its lower end a gear-wheel 6 meshing with a pinion 7 driven by an electric motor 8. The underside of the gear wheel 6 carries a concentric set of equally spaced dogs 9, each arranged to be intermittently engaged by a .spring-loaded plunger 10 forming the core of the motor releasing solenoid 11 which when energized causes the plunger 10 momentarily to retract, the motor 8 thereby driving the gearwheel 6 and shaft 4 according to the spacing between the dogs so that the tape traverses to change its reading by one digit. The upper part of the shaft 4 is hollow to receive a spring- loaded reciprocable rod 13 forming the core of the spool releasing solenoid 14 which has mounted thereon and projecting through a slot 4a in the periphery of the hollow shaft 4 an arm 15 which:may engage one of a series of concentric dogs 16 mounted on the upper flange 2a of the driven spool 2. The radial arm 15 engages a stud 17 on a disc 18 secured to the upper end of the driven spool shaft 4 so that due to the engagement of the radial arm 15 between one of the dogs 16 on the spool and the stud 17, the spool 2 is normally locked with the shaft 4 and rotated therewith. A short current pulse sent to the spool releasing solenoid 14 however causes the rod 13 momentarily to be raised thereby withdrawing the arm 15 from engagement with a dog 16 on the spool 2 which thereby rotates under the action of the spring bias on the supply spool so that the tape traverses to change its reading by one digit. The supply spool may be provided with a cam (not shown) adapted to open switch contacts in the circuits of the solenoids 11 and 14 to prevent rotation of the spools past the limits of the indicia on the tape and also to operate a further set of contacts to operate a limit indicator at a predetermined number. The counter is suitable as an indicating means for the counting device of Specification 785,885, [Group XL (b)], which may register the number of vacant seats on the top deck of a bus.

Abstract: 1,212,765. Limiter diode. GENERAL ELECTRIC CO. 7 March, 1968 [30 March, 1967], No. 11236/68. Heading H1K. A voltage limiting diode for use at liquid helium temperatures in the protection of superconductor circuits has a semi-conductor wafer of a single conductivity type degenerately doped at its opposite faces and lightly doped in the middle, the structure being sandwiched between heat sinks. The diode may be made of silicon or gallium arsenide but the embodiment described makes use of a germanium wafer sandwiched between molybdenum or tungsten discs themselves soldered to copper heat sinks. The wafer may be doped with gallium, indium, aluminium or boron (specifically the degenerate layers are provided by gallium diffusion)or with phosphorus, arsenic or antimony. Appropriately doped indium, tin or lead is used to bond the wafer to the W or Mo discs, and these are soldered to the Cu heat sinks by tin-indium solder. The diode has the characteristic shown, irrespective of the polarity of the applied voltage, and may be connected across the winding of a superconductor magnet energized alternately by the two halves of the secondary of a superconductive transformer gated by two cryotrons.
