Title: Improvements in or relating to binary digital number storing and accumulating apparatus
Inventor: FLOWERS THOMAS HAROLD
IPC: H04M15/18
Filed: 1960-08-22
Abstract: 945,775. Magnetic core binary counting apparatus. H. M. POSTMASTER GENERAL. Aug. 14,1961 [Aug. 22, 1960], No. 29040/60. Heading G4A. A magnetic core binary counter comprises a matrix store M1, each row of which stores a binary number which may be selected for countup by energization of row lines PY1, PY2 to readout and write-back respectively, and five cores CX1-5 in each binary order for registering the count instruction, receiving the digit from M1 and modifying it before write-back. The sequence is as follows:- (1) all cores such as CX1 and 2 are set to 1 by VE6, and cores such as CX3-5 are set to 0 or 1 according as "no change" or "add 1" is instructed. (2) a pulse on a selected line such as RWy1 switches all cores in the row registering 0 to 1 to set the corresponding CX1 and 2 cores to 0 by transistors such as VEX2; this also sets CX3-5 cores back to 0 in higher order (no change to be effected in orders higher than the lowest 0). (3) either CX4 is set to 0, if the digit is to be changed, or CX5 is set to 1 if not. This is done by VE9, and the output in the 'd' windings acts to switch CX2 or 1, if the digit read out was 1 or 0 respectively to write back 0 in the corresponding core by coincidence of currents in the CLX1 and PY2 lines. The order to "add 1", or simply to read out a certain row to a staticisor not shown, is entered on one of the keys such as Ky, with key KS in its shown position for read-out and to the left for count-up, to mark a core of column A (Fig. 3); when the key is released the resetting of the corresponding core of column B (set from the A column by VE4, C1 and VE3) by a PY3 pulse (the row pulses PY1-4 occur in sequence PY3, PY4, PY1, PY2, after which four corresponding pulses are produced for each of the other rows) sets C2. The resetting of C2 sets C3 from which, via transformer TR transistors VE6-9 and line VE1, the timing pulses for Fig. 1 are derived.

Title: Improvements in tyre pumps combined with a cycle frame tube
IPC: B60C23/10
Filed: 1934-10-12
Abstract: 428,271. Air-pumps. ZUCKER, P., 11, Lavaterstrasse, Z³rich, Switzerland. Oct. 12, 1934, No. 29241. [Class 8 (i)] [See also Groups XXXI and XVII] The detachable handle of a tyre pump, combined with a frame tube, works in a slot 6 in the frame tube 1, and means are provided for retaining the plunger in its upper position, when not in use, so that the slot is covered and the entry of dust &c. is prevented. The sliding assembly comprises a tube 4 having a head piece 5 with a transverse passage 7 in line with the slot 6 in the frame tube 1, so that the flat part 16 of the handle 15 may be inserted therein. A spring 10 is coiled on a pin 9 beneath the passage 7, and, when the handle 15 is withdrawn, the spring projects through a slot into the passage 7 and through a slot in the tube 4 to bear frictionally against the inside of the frame tube, thus to resist downward gravitational movement of the sliding assembly. The act of placing the handle into the passage 7 presses the spring downward and withdraws it from contact with the frame tube, the sliding assembly thus being released for operation. The end of the frame tube is sealed by a rubber disc 12 which is squeezed between two metal plates connected by a bolt and nut 13. The squeezing expands the disc 12 radially, and it thus becomes locked in the tube 1. To minimize friction between the handle 15 and the slot 6, a ball 18 is loosely mounted in the handle.

Patent GB-616992-A (GB)
Title: Improvements in and relating to starting switches suitable for electric discharge lamps
IPC: H05B41/06
Filed: 1945-11-06
Abstract: 616,992. Thermal switches. COLE, Ltd., E. K., and MOORE, F. J. Nov. 6, 1945, No. 29427. [Class 38 (v)] A starting switch for a discharge lamp comprises normally-closed contacts 1A, 2A, on bimetal strips 1, 2, in series with lowresistance heaters 7, 10, in the cathode circuit. When main switch C is closed, resistance 10 causes strip 1 to move to the left to break the cathode circuit and cause the lamp to strike. At the same time, the heater 7 causes a bimetallic disc 4 to snap over-centre and bring an extension 4C down to hold the strip 1 in its deflected position, Fig. 3. Contacts 1B and 4D are thus made and insert parallel highresistance heaters 3, 5, in the cathode circuit. The latter heater maintains the disc 4 in the Fig. 3 position, and the former, which has a negative resistance voltage characteristic, does not produce enough heat to move the latch 4C upwards, if the lamp strikes. If it fails to strike, the full voltage is applied to resistance 3 and the latch releases the strip 1 to allow another starting attempt. The switch may be locked out after several unsuccessful starting attempts by slightly heating the strip 2 by resistor 10 so that it gradually moves to the left until strip 1 cannot move away from it. Ambient temperature compensation is obtained by twisting the extension 4C through 180 degrees at 4B and by providing a small bimetal spring 8 pressing against the disc 4 with a pressure varying with the ambient temperature.

Abstract: 1500468 Measuring coefficient of friction R J BRUNGRABER 15 July 1976 [25 July 1975] 29461/76 Heading G1S Portable apparatus for indicating the static coefficient of friction between a floor surface material and a shoe material comprises a base member 12 for disposition on a floor, a vertical first strut 36 carrying a weight 38 at its upper end, the strut 56 being mounted for vertical and horizontal movement, a second strutt 44 pivotally mounted to strut 36 and carrying at its lower end a shoe 56 which projects through base member 12 for placing a sample of shoe material carried by the shoe into contact with the floor and indicating means responsive to movement of the struts to indicate the coefficient of friction. The strut 36 is movable vertically via bearing 34 carried by a  member 32 slidable along rails 18, 20. The weight 38 causes member 22 to slide to the left along rails 18, 20 against the action of control springs 24, 26 until the tangent of the angle between the strut 44 and the vertical equals the coefficient friction, at which point the shoe 56 slips to the right. A rod 68 carries indicia of the coefficient of friction and is coupled to member 22 by a magnetic coupling between the end of rod 68 and a bolt 70 so as to move to the left with member 22. When the shoe slips to the right it presses the lower end of a trigger 60 which is pivoted at 66 and causes a brake block 67 to engage rod 68 and lock it in its position at the time the shoe slips. A detachable plate may be pivotably mounted to base member 12 and may support a piece of floor surface material for testing.
