Title: Improvements in coin and clockwork controlled electric switches
IPC: G07F17/28
Filed: 1931-12-15
Abstract: 382,799. Coin-controlled wireless receiving apparatus. LANGE, C., 40, Jungfernstieg, Hamburg, Germany. Dec. 15, 1931, No. 34734. [Class 27.] Coin action, electricconnection; electricity supplying by time-controlled apparatus.-In a coin and clockwork controlled electric switch for radio receivers of the kind wherein the insertion of a coin enables the user to maintain the electric circuit closed for a predetermined time either continuously or intermittently, the coin 10, Fig. 2, inserted through a slot 7 into a shoot 9 drops initially to insulating plates 12, Fig. 4, carried by a slide 14 and passing through notches 11 in the shoot. A lever 29 turned by a knob 27 from an " off " to an " on " position moves the slide 14 to the right against the action of a spring 24, the slide being retained by a spring-controlled latch 41 engaging a pin 48 on the frame of a clockwork 34. A heel 54 on the lever 29 closes a switch 52 and an insulated spring 55, carried bv the heel 54, is withdrawn from a balance-wheel 56 and starts the clockwork. The movement of the slide 14 allows the coin to drop and rest on the inner edges of a slotted metallic plate 15 carried by the slide and embracing the shoot 9 which is slotted at 16 to receive the inner edges. A spring 22 on the plate 15 presses the coin against the shoot to complete an electric circuit between the shoot and the plate 15. The receiver is connected to two terminals 49, 51 the circuit being completed through the switches 22, 52. The clockwork drives a disc 37 having equi-distant teeth 38 between which the latch 41 engages. As the disc 37 rotates, a tooth 38 depresses the latch for the spring 24 to return the slide 14, the coin then dropping to a wide portion of the slot in the plate 15 to a money-box 26 and breaking the circuit at 22. If there is no transmission, the user turns the lever 29 to its " off " position, breaking the circuit at 52 and stopping the clock. The disc 37 is driven from a wheel of the clockwork through a pin 43, enlarged hole 42 and a spring 44. This allows the disc 37 to position itself so that the latch 41 can enter between two teeth 38. The number of teeth 38 determines the time the clockwork runs for each coin. When the clockwork runs down, its spring engages an insulated block 59 to open a switch 60 in the circuit. Coin-slit closing devices.-While the slide 14 is in operative position with the switch 22 closed, an arm 21 extending therefrom closes the coin-slit 7.

Title: Electron gun assembly for use in multi-beam type cathode ray tube
IPC: H01J3/02
Filed: 1974-08-07
Abstract: 1445645 Electron guns HITACHI Ltd 7 Aug 1974 [8 Aug 1973] 34753/74 Heading H1D In a triangularly arranged triple electron gun assembly for a CRT, in which certain grid electrodes at the same potential in the separate guns are combined into cup-shaped pressed sheet-metal structures each closed by a base with three beam apertures having turned up rims to reduce electric stress, two such structures are mounted base to base to form a lens in each beam. In the prior art the rim height/ diameter ratio in the integral base (Figs. 3, 4 not shown) is limited by the pressing process to #0À3; with this ratio the influence of the walls of the cup on the symmetry of the field in the beam path causes appreciable astigmatism. To raise the effective ratio to #0À5 sufficient to make astigmatism negligible, the integral base of at least one cup 5, 34 is replaced by a welded assembly 45 of two pressed dished triangular plates 40, 50, fastened face to face with aligned openings having rims both turned inwards or turned oppositely on the two plates (Fig. 7 not shown). Alternatively (Fig. 8 not shown) a single dished plate may be welded on the integral base of the cup. Perforated 33 projections 32 are aligned with the beam openings and communicate with the separate cathodic ends of the three guns. The guns may alternatively be arranged side by side in line, and a plurality other than three may be employed. Non- magnetic stainless steel is preferred for the electrode pressings.

Title: Improvements in and relating to fuel injection pumps
IPC: F02D1/00
Filed: 1969-07-11
Abstract: 1,235,033. Regulating I.C. engines. ROBERT BOSCH G.m.b.H. July 11, 1969 [July 13, 1968], No.34953/69. Heading F1B. [Also in Divisions G2-3] A fuel injection pump control device comprises a fuel control rod stop 1 coupled to a piston 7, a control element 39 which permits flow between the cylinder 8 and the return line 33 or the supply line 34, the control element being operable by actuating means in dependence on whether the engine starter 57 is operating, the quantity of hydraulic medium supplied to the cylinder being determined by a sensing element which responds to at least one of the variables which affect the engine performance. Operation: As shown the engine is stopped, cold and the starter is switched off, with supply line 34 corrected via groove 45a, line 31, passages 46, 50 to chamber 51. The control stop 1 allows the fuel control rod 3 to assume position I allowing excess fuel for starting. Element 23 acting in response to the low-temperature of the engine coolant allows the control slide 13 to move into the position shown in which passages 46, 50 communicate through annular groove 48. Operation of switch 59 in the starter circuit causes an electromagnet 41 to move the control pin 39 into the position where line 31 is closed, the pressure is thereby prevented from acting on piston 7. When the engine is running and glow plug and starter 57 are switched off the electromagnet 41 is de-energized and spring 42 returns the control pin to the position shown and results in the raising of piston 7 until surface 49 interrupts the communication between passages 46 and 50. In their position the arm 1a is in the position II corresponding to full load quantity. Throttle 54, which may be adjustable, delays pressure build up so that excess fuel is available until the engine can run with the full load fuel quantity. Glow plug heating may be continued by switching off the starter 57 with an auxiliary switch 60. If the coolant temperature in duct 21 rises, the control slide 13 is lifted so that passages 46, 50 communicate and piston 7 is lifted until these passages until communication ceases. This rotates arm 1 to reduce fuel-flow. When the engine is stopped e.g. by moving the control rod 3 to position III with cut out magnet (not shown) the oil pressure in line 34 drops and piston 7 moves to stop 52. A temperature sensitive switch 61 may be arranged between the circuit 55 and the electromagnet 41. The electromagnet 41 may be consisted so that it depends on the operation of the resistor 56 and/or the starter motor 57.

Filed: 1956-11-23
Abstract: <PICT:0799876/III/1> A mixture of silicon tetrachloride and hydrogen is passed through a high-temperature reaction zone so as to cause the production of silicon and hydrogen chloride to a substantial extent, the silicon is allowed to deposit in said zone the gaseous reaction product, which consists of a mixture of hydrogen chloride and unreacted silicon tetrachloride and hydrogen, is removed from the reaction zone, the hydrogen chloride is removed from said mixture and further silicon tetrachloride and hydrogen added thereto to replace that used in the reaction, and the resulting mixture of silicon tetrachloride and hydrogen is recycled to the high temperature reaction zone.  The silicon may be produced at a temperature of 1100-1300 DEG  C., preferably 1200 DEG  C.  Removal of hydrogen chloride and addition of hydrogen may be effected simultaneously by reaction of the hydrogen chloride with vaporized zinc at a temperature of 600-800 DEG  C., preferably 650 DEG  C.  As illustrated, silicon tetrachloride is introduced from reservoir 30 into the cyclic system after the high temperature reaction zone 31. Zinc vapour is then introduced into the system from zinc boiler 33. The zinc chloride thereby produced is removed by means of a cooling and settling chamber 34 and filter 35 of glass wool.  The remaining hydrogen and silicon tetrachloride pass via pump 36 to reaction zone 31.  Before passing to zone 31, a portion of the gases may pass continuously or intermittently through an analyser 37 consisting of an infra-red analysis unit or a thermal conductivity cell.  Hydrogen for commencing the reaction, and for subsequent supplementary addition, if necessary, may be added via reaction tube 32. Silicon tetra chloride for use in the process may be purified by admixing with a solvent, e.g. dichloromethane, trichloromonofluoromethane, or trichlorotriflorethane, passing through activated alumina boiling off, condensing, and recycling the solvent (Fig. 2, not shown).
