Abstract: 1,089,151. Electrostatic generators. N. FELICI. Jan. 8, 1965 [Jan. 9, 1964], No. 996/65. Heading H2A [Also. in Division G3] The output voltage of a rotatable eleotrostatic generator having a constant excitation voltage is regulated by varying the speed of rotation of the generator. In one embodiment (Fig. 1, not shown), the generator is driven by a permanent magnet D.C. motor supplied over a resistor or a barretter from a constant voltage source. The load torque of this type of generator is proportioned to the output voltage; thus, the driving motor tends to slow down when the output voltage tends to increase, whereby the output voltage is maintained within acceptable limits. The driving motor may be shunt wound with a series bucking winding (Fig. 3, not shown), or may have a shunt winding associated with two regulating resistors (Fig. 5, not shown).

Abstract: 1,050,499. Cooling systems for engines. BARLOW VAPOR COOLING CO. May 11, 1965 [May 13, 1964], No. 19910/65. Heading F4U. In a closed circulating cooling system for I.C. engines a vaporizable liquid coolant is maintained at its boiling point throughout the circuit a portion of the coolant being vaporized in the engine jacket 1, the vapour being separated in a chamber 13 and a portion of the liquid returned direct to the jacket at its boiling point through a pipe 17 so as to cool the cylinders uniformly from bottom to top. The coolant is circulated by a pump 7 and leaves the engine jacket by a conduit 19 opening into the chamber 13 directly above the return pipe 17 forming a short-circuit of coolant flow through the chamber. The chamber 13 contains a number of vertical barriers 15, Fig. 2 (not shown), of metal grids or non-woven fibre filters so that entrained liquid is deposited from coolant passing along the chamber. The separated vapour passes through an aperture at the other end of the chamber 13 to a condenser 9 with cooling fan 11. Condensate collecting at the bottom of the condenser 9 is fed by a pump 25 to the end of the chamber 13 remote from the conduits 17, 19. An air vent 27 with a one-way relief valve prevents build-up of pressure in the system. A filler cap 65 is so located on the chamber 13 that the system cannot be filled above the level A. The working level B in the chamber 13 is below the level in the cylinder jackets.

Abstract: 1,053,530. Lift control systems. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 23, 1965 [Nov. 26, 1964], No. 48140/64. Heading B8L. An automatic lift control system comprises first and second switches respectively operable at first and second levels between each pair of adjacent floors by passage of the lift car therebetween, successive first and second levels defining occupancy zones for the floor between them for upward and downward lift car movement respectively. Car-calls and floor-calls are registered, and an arrangement of logically interconnected static switching units respond to operation of the switches for determining, in dependance on the order in which they are operated, the position of the lift car in relation to the occupancy zones of each floor. Request units, governed by the position-determining units and responsive to a registered call, emit an up-request signal when the car is determined as being below the floor concerned, and a downrequest signal when the car is determined as being above that floor. The request signals conditionally initiate car movement in the relevant direction. Stop units, also governed by the position-determining units and responsive to a registered call, emit a stop-signal following entry of the car into the occupancy zone of the floor concerned. Each floor, other than the top floor, has an individual memory unit with feedback input, respective units being connected through delay units to corresponding memory units for the next floors up and down. Input signals for the memory units are temporarily switched on or off in accordance with cardirection when the car is between floors, each unit requiring three inputs to provide an output whereby the several units are switched on or off in succession according to the car-direction. The memory unit for the bottom floor has an input controlled by a limit switch, whilst each memory unit for a floor receives an inhibiting signal from a top limit switch. A directional preset condition is maintained temporarily when the car is approaching a floor and no further calls in the preset direction remain unanswered, so allowing a car-call to override calls in the other direction.

IPC: G11B11/105
Abstract: 1,143,836. Recording and playback; magnetic storage apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 16 May, 1966 [26 May, 1965; 30 June, 1965], No. 21620/66. Headings G4C and G5R. [Also in Division H3] A cryomagnetic storage system operates by prerecording a predetermined pattern on a layer of magnetic material having a coercivity temperature relationship exhibiting a transition where the coercivity decreases rapidly with increasing temperature and maintaining the layer at a temperature such that the material is in a stable state close to the transition. To record a data bit in a particular position, the magnetization temperature condition of the material at that position is temporarily transferred to a metastable state on the other side of the transition, and the direction of magnetization is then charged. The magnetic material may be ferrous ferrite 12 supported on a tape 11 and is initially uniformly magnetized in a direction 15 opposite to a magnetic bias H applied at a recording station 13. The system is contained in uniform temperature enclosure just below the transition point. To record data bits at particular points along the tape, the tape is irradiated as the required point passes the recording station by an electron beam, to raise the temperature to above the transition. The bias field, which is not strong enough to overcome the steady magnetization at below the transition, is now strong enough, and magnetic switching occurs. The stored information may be read out by an optical system at 14 making use of Kerr or Faraday effects. By arranging that the prerecorded magnetization along the film alternates in direction at adjacent bit positions, the external biasing field may be dispensed with, the magnetization in surrounding bits being sufficient to reverse that of a particular bit when irradiated. A coincident current matrix store may comprise a magnetic film 40 initially magnetized in a direction opposite to a bias field H which is insufficient to reverse the magnetization. Coincident currents in the X and Y directions act to heat the film sufficiently at the selected bit to cause the transition to occur, whereupon the field H is sufficient to switch the film at that bit, to store information. An alternative matrix type store (Figs. 4A and 4B, not shown) provides wires at the bit locations normal to the memory plane, which is backed by an earthed sheet. Current to a particular wire heats the related location and enables the required transition to occur.

Abstract: 1,232,992. Selective signalling. J. M. BENTLEY-BEARD. 2 Aug., 1968 [4 May, 1967], No. 15259/67. Heading G4H. In a noughts and crosses playing machine the initial machine moves are made at random and subsequent moves are made by a programme device in accordance with the moves already made unless a combination of moves has been made that is not recognized by the programme device in which case a further random move is made. A relay circuit, using conventional techniques, is described for controlling a coin freed machine. As described, the first two machine moves are random, each of these being selected by stopping a self-stepping ring counter, whose stages correspond to the squares of play, at a position corresponding to the first vacant square immediately after the instant a randomizing capacitor becomes discharged, the capacitor having been charged for the period between the making of the immediately previous machine and player moves. Subsequent machine moves are made as a result of analysing all previous moves, this being effected by an eightbank 25-position rotary switch and three associated relays, the switch being stepped through four revolutions to look for one hundred different combinations of moves. If a combination is recognized the appropriate move, determined by the switch position is made by the machine. If the existing combination of moves is not recognized a random move is made. Random moves can be weighted in favour of the centre position of the playing area by allotting more than one stage of the ring counter to the centre position.
