Title: Improvements in or relating to calculating machines
Inventor: DRAGE JAMES JOHN
IPC: G06F7/498
Filed: 1965-02-26
Abstract: 1,124,623. Calculating machines. BELL PUNCH CO. Ltd. 25 Feb., 1966 [26 Feb., 1965], No. 8467/65. Heading G4A. A calculating machine has two registers, a calculating register and a store register, each comprising a plurality of pulse counting stages, means being provided for transferring into the stages of one register numbers of pulses equal to the numbers stored in the other register. The keyboard operated calculator described in Specification 1,029,953 is provided with a storage register comprising a plurality of decimal counter stages whereby intermediate results of calculations may be stored and used in further calculations at a later stage. Seven switches 1-7 (Fig. 3) are provided for controlling the following operations: (i) subtraction of number in calculator register (CR) from number in storage register (SR) whilst retaining CR unchanged, (ii) addition of CR and SR whilst retaining CR, (iii) transfer of SR to CR whilst retaining SR, (iv) clearing SR, (v) transfer of SR to CR with clearing of SR, (vi) addition of CR to SR with clearing of CR, (vii) subtraction of CR from SR with clearing of CR. Operation of the switches 1-7controls the opening and closing of AND gates 8-12, which control the passage of pulses originating in the calculator circuit along a line 13 to a storage register drive 17. AND gates 34, 35 and 36a, which are also controlled by the switches 1-7, control the passage of pulses from the storage register through to Highway Output 38 which connects with highway H in the calculator. The method of transferring numbers for the operations referred to is to apply ten pulses to each stage of one register in turn and to open or close appropriate gates controlling the passage of pulses to the stages of the other register when the zero conditions are reached. A single stage of a decade pulse-counter circuit comprising the storage register is illustrated in Fig. 4 comprising four transistor flipflop circuits 61, 66, 70 and 69 having the binary values 1, 2, 4, 2, respectively. Circuits 61, 66 and 70 are connected in cascade except that after the first pulse has been received and circuit 61 has been set, the next stage to be set is 69. Setting of circuit 69 causes gate 64 to be opened thereby allowing the three circuits 61, 66 and 70 to continue to operate in the normal cascade manner. After the tenth pulse the counter returns to its initial state. The zero state may be obtained by applying either a negative potential to line 76a or a positive potential to line 77 or by applying pulses to the input 51 until the carry signal is received at the output K. Elements 53-55 form an AND gate at the input to the counter.

Title: Improvements in or relating to calendering, and cutting sheet material on the bias
IPC: B29D30/46
Filed: 1932-03-24
Abstract: 397,233. Cutting sheet material. DUNLOP RUBBER CO., Ltd., 32, Osnaburgh Street, London, WILLSHAW, H. and NORCROSS, T., Fort Dunlop, Birmingham. March 24, 1932, No. 8802. [Class 31 (i).] To obviate the waste at the ends of rolls of sheet material that are subsequently to be cut into bias strips, the sheet material, as it comes from the " calender " where it has been coated or similarly treated, is cut on the bias at positions corresponding to the two ends. The invention is concerned more particularly with the rolls of coated fabric for the production of bias strips for the carcasses of tyres. In one form of the invention, sheet material from the calender 1, Fig. 1, passes to cooling means 4 and thereafter to a bias cutter 2 which takes the form shown in Fig. 2 of traversing knives 8 carried bv a chain 9. The chain is driven from a roller 10, through gear-box 11, a one-revolution clutch 12, and gearing 13, and is controlled by a measuring device 14, rotated by gearing 15 from the roller 10. The roller 10 is driven by chain gearing 3 from the cooling means 4, which is driven by a motor 5 synchronized in known manner with the motor 6 driving the calender. The gear-box 1 allows of varying the angle of the bias cut. In a modification, the cutter is in the form of a roller with helical cutting blade covering part only of the roller, thereby allowing passage of the sheet between the roller and a lower roller when the helical blade is not in the cutting position. Alternatively, the roller carrying the helical blade may be brought into and out of operative position.

Title: Modulating light for use in optical communications
IPC: G02B6/30
Filed: 1974-02-27
Abstract: 1468031 Controlling light WESTINGHOUSE ELECTRIC CORP 27 Feb 1974 [28 Feb 1973] 8816/74 Heading G2F Light propagating in an optical waveguide with a thickness not greater than 2 degrees wavelengths is modulated by passing bulk ultrasonic acoustic waves through the guide at 90 degrees to the propagation direction. The acoustic waves may be longitudinal or shear waves, and the modulated light is deflected to regions either side of the original beam, the intensity of the latter therefore being varied. The frequency of the deflected light is shifted by the acoustic frequency, with 180 degrees phase shift between corresponding regions on opposite sides of the original beam, and the polarization of the original and deflected beams are identical. In addition shear waves mode convert and frequency shift some of the light, which propagates collinearly with the original beam. All the light is phase modulated at the acoustic frequency. The acoustic wave may be produced by a transducer, e.g. a thin film of sputtered zinc oxide, on the guide surface or spaced therefrom by an acoustic delay means such as fused silica. In either case the bond to the waveguide should include a material with a lower refractive index than the guide to prevent light loss, additional layer being provided for this purpose if necessary. Acoustic resonance may be obtained or avoided by adjusting the guide thickness, or providing an acoustic absorber or delay line to prevent reflection, respectively. Alternatively the guide may be of a Piezo-electric material such as polyvinylidene fluoride, polyvinyl fluoride, polycarbonate or polypropylene, electrically poled if necessary, electrodes being provided on opposite surfaces of the guide and being spaced therefrom by low refractive index optically isolating layers. Acoustic resonance is determined by the guide thickness.

Abstract: 183,520. Barchiesi, A., Baratta, A., and Orrico, A. March 22, 1921. Thermally -actuated valves.-A device adapted to shut off the supply to a gas burner in the event of the flame being extinguished, comprises a lift valve adapted to be opened by hand and retained in the open position by a pivoted catch subsequently released by thermal elements acting through pawl and ratchet mechanism. The lift valve member 95 is mounted on a spindle 96 guided in a recess 27 provided with a vent 28 and engages a seat 24 externally screw-threaded and connected by a side passage 19 with the outlet connection 114. The inlet connection is screwed on to the seat member and holds a split casing 106, 107 against the shoulder on the base 18. The valve is opened by an arm 98 on the spindle so as to cause a triangular stop 97 to pass over a stop-pin 70 on a spring-pressed lever 66. The lever carries a spring-pressed pawl 76 which normally engages a ratchet-wheel 85 but which is temporarily released therefrom each time the valve is opened by an arm 105 engaging a pin 77. A lever 86 connected to the ratchet-wheel is acted on by the free ends of a pair of spiral springs 54, 55 subject to the heat from the burner through a tubular member 50 so as to cause the wheel to ride over the pawl while the springs are warming up when the burner is first lighted, but causes the wheel to engage the pawl positively as the springs cool to tilt the lever 66 and release the catch to allow the valve to close. In a modification the springs are expanded by the heat from an auxiliary burner arranged in a glass case.

Abstract: 1428623 Saturable magnetic switches ILLINOIS TOOL WORKS Inc 27 Feb 1974 [27 March 1973] 8926/74 Heading H3X [Also in Division G1] A switch, Fig. 1, comprising two transformer cores 11, 12 alternately saturable according to the position of a movable magnet structure 16, 17, is continuously monitored during use by a fault detecting circuit. The switch cores, which may be structurally combined, Fig. 3, have a common primary winding 13 and series opposed portions of a secondary winding 14 so that the condition of zero output can obtain only if the switch or associated winding is defective. Monitoring is effected by a continuous signal fed to the primary winding, the position of the switch when functioning correctly being denoted by the phase of the continuous signal in the secondary winding. The continuous signal may be sinuosoidal, or a train of unipolar or bipolar pulses. A monitoring circuit 40 is shown in Fig. 5 in which the secondary winding output is applied to a phase detector circuit 44 after high pass filtering at 42, 43. Both phases of transformer output are detectable by applying positive and negative pulses in appropriate synchronism though respective detector circuit resistors 47, 48. The selected positive or negative pulses emerging from the detector circuit are smoothed by a filter circuit 50, 51, and then pass to a switch failure detector circuit comprising an inverter 53, a dual input gate 54 and a time delay circuit 56. An arrangement for monitoring a plurality of switches SW 1 -SW n , Fig. 6, under the control of a diagnostic programmer 79 is described. Each phase detector 73, 74 produces an output on a respective lead 81, 82 which is applied to a level detector 75, 76 and directly to a diagnostic comparator and logic circuit 77. The outputs from the level detectors also pass to circuit 77 through a gate 78. A test sequence may be initiated by the programmer 79 which controls the output from a reference oscillator to the switches and positive and negative pulses to the phase detectors.
