Title: A device for measuring the discharge voltage of primary or secondary-cells
IPC: H01M10/48
Filed: 1951-06-14
Abstract: 679,106. Batteries and cells; testing. GIBIAN, R. June 14, 1951 [June 21, 1949], No. 14150/51. Classes 37 and 53. In a device for measuring the discharge voltage of a cell independently of the internal resistive voltage drop but taking account of the depolarization voltage, a self-interrupting vibratory switch 5. (Fig. 1), operates at, e.g., 50 c.p.s. to alternately connect a gas depolarized primary cell 16, having a central tubular carbon electrode 2 sealed through a sleeve in the bottom of a zinc vessel 1 containing caustic potash solution, across an adjustable load 7 in series with a milliammeter 6, and across a high resistance voltmeter 13 or a voltage measuring potentiometer 10 and galvanometer 9. Switching impulses are avoided by bridging the vibrator contacts by condensers 12. Air or oxygen passes into the bore of the electrode 2 and diffuses through the pores of the carbon to the boundary of the electrode and electrolyte where it acts as a depolarizer. Since the action is sluggish, the state of depolarization does not substantially change while the cell is connected to the voltage measuring device, which indicates the E.M.F. of the cell minus the depolarization voltage for the load current indicated on milliammeter 6. The contact period on load may be arranged to be longer than that during voltage measurement. In a modification, Fig. 3 (not shown), the load resistances may be alternative current-controlling iron-hydrogen resistances and the voltage measuring device may be connected over a change-over switch to the off-load cell E.M.F., the voltage across the load resistance, and the vibratory switch. The vibratory switch may be replaced by a cyclically-operating electronic switch.

Title: Improvements in or relating to electrical signalling systems
Inventor: DAVIS JOHN CHRISTOPHER HAMMOND
IPC: H03M1/00
Filed: 1961-05-01
Abstract: 972,484. Electric selective signalling systems. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. April 27,1962 [May 1,1961], No. 14319/64. Divided out of 972, 483. Heading G4H. [Also in Division H4] In a decoder for a pulse code modulation sysem in which signals having a maximum value of 16i are encoded in increments of i in a four digit cyclic permutation binary code using e.g. the encoder described in Specification 972,483, each digit controls the direction of current flow in one of four serially connected stages to each of which a fixed fraction of the maximum value of the signal is applied. The first stage to which a current of 1/ 2i  is applied comprises a pair of transistors VT11, VT12 with their bases connected respectively to a terminal E11 to which a fixed voltage is applied and to terminal D1 to which a signal representing the least significant code digit is applied. When the digit is "1" the bias of VT12 exceeds that on VT1 and the current of <SP>1</SP>/ 2i  flows directly to the output of the stage and when the digit is "0" the bias arrangements are reversed and the current flows via VT1 to a phase reversal circuit including transistor VT13 and resistors R1l R12 and appears in the output of the stage as -i/2. Injection of a current of i at the output of the stage provides an input to the second stage of either <SP>1</SP>/ 2i  or 1¢. The second stage and the subsequent third and fourth stages (not shown) are identical to the first stage but provide for the injection into their output stages of currents of 2i, 4i and 8i respectively. In dependence on the code the decoder provides output currents differing in steps of i in the range ¢i - 15¢i.

Abstract: 1,185,371. Rotary hydraulic motors and pumps. A.A. SCHMITZ. March 29, 1967, No.14372/67. Heading F1F. A rotary hydraulic motor (or pump) comprises a first member having an exterior surface, a second member having an exterior surface encircling the exterior surface and means mounting said members for relative rotation therebetween wherein one of said members includes a plurality of segments defining a plurality of axially extending channels slidably receiving vanes and each channel has at least one spacer brace and each vane a notch or notches to receive the brace or spacer braces. As shown, a first inner member, a stator 40, Figs.1 and 2, having a contoured surface 42 is fixed to a tubular member 56 secured, e. g. to a vehicle and encircled by a second outer member, a rotor 21, consisting of an end plate 12 having a plurality of axially-extending segments 18 defining therebetween parallel-sided channels 28 slidably mounting vanes 30 urged by springs 39 into engagement with the contoured surface 42 and an end plate 14. The plates 12, 14 are peripherally machined to receive a ring 26 formed with lugs L for attachment to the vehicle tyre rim. Within the tubular member 56 is slidably mounted a tubular valve spool 66 which on movement of an operating lever 80 controls the supply and exhaust of hydraulic operating fluid to and from the motor. Fluid is admitted through an inlet 84 and passes through radial ports 86, annular passage 70 and radial ports 91 to one or both sets of axiallyspaced radial inlet ports 92, 93 to act on the vanes 30 and is exhausted through a set of radial ports 90 and an annular passage 75 between the valve spool 66 and the tubular member 56 and an exhaust port 95. To double the speed of the motor and halve its torque the lever 80 is moved anti-clockwise to isolate the set of ports 93 from the inlet port 84 and connect them to the exhaust port 95 so that only half the displacement chamber between the rotor 21 and stator 40 are used. Instead of the stator having four lobes as shown, it could have eight or more lobes and the sets of axiallyspaced inlet ports could be increased to three or more to permit of three or more operating speeds and corresponding torques. To prevent deflection of the segments 18, spacers 35, Fig.4, are fitted therebetween and the vanes are notched at 34 to receive the spacers. Leakage fluid collecting at the inner end of member 56 passes through operating shaft 65 and radial ports 103 to a drain port 104.
