Title: Improvements in or relating to coin collecting mechanism, particularly for telephone apparatus
Inventor: HALL FREDERICK WILLIAM
IPC: H04M17/02
Filed: 1954-03-01
Abstract: 756,591. Coin-freeing mechanisms. HALL TELEPHONE ACCESSORIES, Ltd. March 1, 1955 [March 1, 1954], No. 5939/54. Class 27. Coin-freeing mechanism of the type having a counter-weighted balance arm 5 moving under the weight of a predetermined number of coins to condition apparatus, such as a public telephone, for operation, can be adjusted to operate at an increased charge by fitting a counterweighted lever 17 which has a cranked portion 20 disposed in the coin path 2 and a stop 16 normally lying under but spaced from an abutment 15 on the balance arm. When the charge is increased from threepence to fourpence, the first two pennies, after momentarily tilting the lever 17 about its pivot 18, enter the coin chamber 3 and rest on a pin 4 on the balance arm, without moving it. The third penny lowers the arm but full movement is prevented until the fourth penny tilts the lever 17 and removes the stop 16 from the abutment 15. Full movement of the arm under the weight of the three pennies reinforced by the arrival of the fourth penny on the pin 4, causes an extension 9 to close contacts 10 and 12 and thus condition the telephone circuit. The counterweight 7 for the balance arm is replaceable and adjustable for varying the charge. Buttons A and B swing the chamber 3 to left or right respectively so that the coins fall either to a coin box or to a return shoot 13 and the stop 16 is bevelled at 16A to facilitate return of the abutment 15 to initial position.

Patent GB-652298-A (GB)
Title: Improvements in or relating to sawtooth generators
IPC: H03K4/14
Filed: 1948-02-27
Abstract: 652,298. Saw-tooth generating circuits. DEPARTMENT OF COMMERCE, DIRECTOR OF THE OFFICE OF TECHNICAL SERVICES OF. Feb. 27, 1948, No. 5961. Convention date, Aug. 30, 1945. [Class 40 (vi)] In a circuit for generating a saw-tooth voltage of constant peak amplitude a synchronizing pulse triggers a pulse generator the output from which starts a saw-tooth voltage sweep which is fed back to cut-off the pulse generator when the saw-tooth voltage reaches a pre-determined amplitude. Fig. 2 shows a multi-vibrator which is synchronized by the negative-going pulse applied at grid 20. When valve 24 is rendered conducting the negative-going pulse at its anode cuts-off the normally conducting valve 40 and terminates the charging of capacitor 43 which discharges exponentially through resistor 42 until valve 40 is conducting again. The drop in potential at the anode of valve 40 is applied to cut-off valve 24 and terminates the negative-going output pulse from the multi-vibrator. Valve 40 is rendered conducting and capacitor 43 commences to charge. In a modification, Fig. 3 (not shown), the output of the saw-tooth sweep generator is applied via a cathode-follower buffer stage to a blocking oscillator so that when the saw-tooth voltage reaches a given amplitude the blocking oscillator generates a pulse which terminates the output from the pulse-generating circuit. In another modification, Fig. 4 (not shown), the pulse which terminates the output of the pulse generator is derived from a regenerative amplifier which is fed via a cathode follower buffer stage from the output of the sawtooth voltage generator. Fig. 5 shows a further modification in which the output of the sweep voltage generator 71 is applied via a buffer stage 72 to a potentiometer 73 which is adjusted so that when the saw-tooth amplitude exceeds a given value amplifier valve 77 is rendered conducting and due to the feed-back transformer 75 a positive pulse appears across winding 82 to render valve 84 conductive and to cut-off the pulse generator 70. In a further modification, Fig. 6 (not shown), the pulse generator comprises a flip-flop which on triggering applies a pulse to the sweeping circuit to generate a saw-tooth voltage. When the voltage reaches a given amplitude a switching valve is rendered conductive via a buffer stage to retrigger the flip-flop to the original stable state and thus terminates the sweep of the saw-tooth generator. Specifications 588,672 and 622,277 are referred to.

Title: Improvements in or relating to methods of producing three-dimensional articles that are similar to three-dimensional originals
IPC: B44C5/06
Filed: 1959-02-20
Abstract: 939,261. Cutting stone. G. M. REID. Jan. 20, 1960 [Feb. 20, 1959], No. 5966/59. Class 124. A method of producing a three-dimensional figure from a model comprises mounting the model so that it may be rotated, projecting, by means of a light beam, a shadow of at least one side boundary of the model on to a screen, providing a rotary cutting tool adjacent the block and movable in the plane containing the axes of rotation of the block and the tool, scanning the edge of the shadow by a device connected to the tool, turning the block and the model through the same small angle and again scanning the shadow, repeating the turning and scanning until both model and block have turned through a large angle, e.g. 360 degrees. The axes of rotation of the model and the block may be parallel or at right angles to one another. As shown, light from a source 5 may project the shadow of a model 1 on to a board 6, a mirror 11 turning the beam through 90 degrees. A pointer 9, connected directly to a tool 8, may scan the outline of the shadow, the tool 9 following the pointer exactly and cutting the block. The edge of the shadow may be scanned by a light-sensitive device connected to mechanism controlling the movement of the tool. Specification 939,262 is referred to.

Title: Improvements in or relating to television systems
IPC: H04N5/12
Filed: 1933-02-27
Abstract: 402,629. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, London.-(Assignees of Tolson, W. A. ; 631, Jefferson Avenue, Erlton, and Duncan, J. R.; 341, N. 41st Street, Camden, both in New Jersey, U.S.A.) Feb. 27, 1933, No. 5967. Convention date, Feb. 27, 1932. [Classes 40 (iii) and 40 (v).] A saw-tooth or other special wave form 40 for controlling a cathode ray 15 is generated by means of a back-coupled thermionic valve 20, 20a. When current begins to flow through the valve, the positive coupling between the anode coil 21<1> and the grid coil 23 causes the current to increase to saturation and then to decrease to zero. Grid current, flowing while the grid is positive 29, accumulates on a condenser 22 and prevents another current impulse until the charge has sufficiently leaked away through a resistance 24. This period is slightly longer than the period between synchronising signals, which make the grid potential sufficient to start the next current impulse. The current impulses 30, 31 are passed by a transformer 21 to a rectifying-valve 32, which produces negative peaks 34 in its anode circuit. A condenser 35 and resistances 36, 37 alter these peaks to the form 39, which is amplified by a valve 38 to develop a saw-tooth current 40, which is passed through coils 17 to deflect the ray 15 horizontally. The current for vertical deflection is derived from a similar valve circuit 19a with an appropriate time constant for the circuit 22a, 24a. The synchronising signals 28, 48, controlling the horizontal and vertical movement respectively, differ in the steepness of their wave front, as described in Specification 395,499, and are separated by a filter 47. Specification 394,597 also is referred to.

Abstract: 1,127,722. Automatic voltage control. MATSUSHITA ELECTRONICS CORP. Feb. 8, 1967 [Feb. 24, 1966], No. 6018/67. Heading G3R. [Also in Division H2 ] The shunt stabilizer valve of a television flyback type E. H. T. generator becomes conducting only when a further rectifier has warmed up, so as to protect the E. H. T. rectifier. The shunt stabilizer valve 9 is initially biased off by the connection of the H. T. supply 10 to the cathode but this bias is offset by a bias from the focusing supply rectifier 19 as it warms up, the latter rectifier having a similar warm up time to the E. H. T. rectifier 7 and both rectifiers having their cathode heating supplies derived from the output transformer. The bias also provides the stabilizer control voltage.

Abstract: 752,261. Fuel-injection pumps. DAIMLER. BENZ AKT.-GES. March 5, 1954 [March 5, 1953], No. 6567/54. Class 102(1). To increase the amount of fuel delivered by a fuel-injection pump to an internal-combustion engine, preferably of the Otto-type, on increase in engine speed, the usual circular pump return port 7, Fig. 2, in the pump cylinder, is replaced by circular ports 8, 9, 10, having a total area equal to that of the port 7. The ports are arranged in increasing cross-section with respect to the control edge 5 of the piston 1, so that on the pump delivery stroke, the cross-sectional area of the return-flow passage increases less rapidly than with a single port to delay the termination of delivery and hence increase the amount of fuel per stroke delivered to the engine. The ports may be of other than circular crosssection and may be replaced by a substantially triangular-shaped port 11, Fig. 3.

Abstract: 1,204,621. Knitting-apparatus; pattern drums. ELITEX-ZAVODY TEXTILNIHO STROJIRENSTVI GENERALNI REDITELSTVI. 12 Feb., 1968 [13 Feb., 1967], No. 6793/68. Headings DIC and DIE. Apparatus for inserting pins into a pattern drum 8 for a knitting or other textile machine and thereby setting up a pattern comprises a shaft 4 on one end of which the pattern drum 8 is mounted and on the other end of which a guide pattern 6 is mounted to indicate the arrangement of the pins to be inserted in the drum. The guide pattern 6 and pattern drum 8 are periodically manually rotated by a control 18 to adjust the alignment of the holes in the drum 8 with the nose of a headpiece 12 through which the pins are ejected on operation of a lever 20 to be projected into an aligned hole in the drum 8. The drum 8 and guide pattern 6 mounted on the shaft 4 are also attached to a slide 2 which on manual manipulation of a control 19 causes the drum to move longitudinally. Consequently the pattern drum can be rotated and moved longitudinally by manual manipulation of the controls and pins projected into the surface of the drum according to the guide pattern 6 which is followed by a pointer 14. To rotate the shaft 4 the control 18 is attached to a lever 36 which when depressed actuates a pawl slide 45 causing rotation of a ratchet wheel 50 secured to the shaft 4, Fig. 7. The control 19 which is depressed to permit the shogging of the slide 2 and the longitudinal movement of the pattern drum has its movement transmitted through a lever 58 Fig. 8, and cord 56 to advance a pawl slide 60 which moves a rack 67 permitting an abutment 69 to release a stepped bar 73 controlling the slide 2 against a spring 70. Consequently the slide can be adjusted step by step to allow the pattern drum to move correspondingly longitudinally. The lever 20 when operated permits a slide 81 to draw a pin 15 from a magazine into alignment with a plunger 88, Fig. 10, which is engaged by an arm 79b of a lever 79 to project the pin 15 into the drum 8.
