Title: Improvements in or relating to coin freed vending machines
Inventor: KURK ANTHONY ARSENE NUBAR
IPC: G07F15/02
Filed: 1956-11-05
Abstract: 813,763. Coin-freed vending apparatus. SERVUMATIC Ltd. Feb. 4, 1958 (Nov. 5, 1956], No. 33705/56. Class 27 In a coin-freed machine having a delivery member and a stop element associated with a coin-released catch member, means are provided for engaging the catch member so as to release the delivery member for a full free operating stroke after a predetermined number of coin-freed operating strokes have been made. As applied to the vending machine described in Specification 756,377, the rotatable delivery member 17 has a sleeve 50 extending round the tube 14 on which the member 17 is rotatable and ratchet teeth 51 on the sleeve engage a spring-loaded pawl 63 so that a second sleeve 59 is indexed step-by-step each time the delivery member is moved through a full stroke. After a predetermined number of strokes, a recess 64 comes opposite the arm 54 of a bell-crank lever 53 and allows it to move out of a recess 52 in the sleeve 50. The other arm 55 of the lever 53 then engages a recess 58 in a lever 56 pivoted at 57 and the latter lever is locked so that for the next stroke of the delivery member, it acts on the catch member 39 in the same manner as an inserted coin and allows one free delivery of an article or commodity. Sleeve 59 is connected by a tube 60 to a pointer co-operating with a fixed mark to indicate that the next operation is "free". Additional teeth may be provided on sleeve 50 so that the idle movement permitted to the delivery member prior to the insertion of a coin will cause the sleeve to take up a position in which it will not, after subsequent full operative strokes, reach a "free" position. One or more idle movements, dependent on the number of additional teeth must then be made to restore periodic "free" operation. As applied to the machine shown in Fig. 5, in which annular recessed members 68 on a shaft 69 rotatable by a knob 70 vend articles 66 one by one from a rack 65, a coin carried in a drum 73 on the shaft raises a spring-loaded pawl 72 from a ratchet wheel 74, one or more teeth of which are rendered inoperative to allow periodic ''free'' operation. This may be done omitting or removing a tooth or by forming an integral or removable ramp or cam surface in the space between two teeth or by fitting on the ratchet wheel an arm which periodically raises the pawl 72. A ratchet 75 and pawl 76 prevent reverse rotation. In a machine in which a slidable delivery drawer is normally locked by a coinreleased lever, a disc to which a predetermined angular movement is imparted on each operation of the drawer has a projection periodically engaging the lever to allow "free" operation of the drawer.

Title: Improved manufacture of phthalocyanine compounds
IPC: C09B47/06
Filed: 1936-12-09
Abstract: Tin phthalocyanines are manufactured by heating together to reaction temperature a phthalic anhydride, or the corresponding free acid or its ammonium salt, amide or imide, with urea and tin or a substance containing it, e.g. a salt thereof, if desired in the presence of ancillary agents described in Specifications 464,673 and 476,243, e.g. boric acid or compounds of molybdenum, and, if desired, with the addition of an additional flux, e.g. kerosene, chloronaphthalene or nitrobenzene.  Metal-free phthalocyanines are obtained by dissolving the tin phthalocyanines in a sulphuric acid medium and diluting the solution with water.  In examples, the following mixtures are heated: (1) phthalic anhydride, urea and stannous chloride; (2) phthalic anhydride, urea, stannous chloride, boric acid and ammonium molybdate; (3) 4-chlorophthalic anhydride, urea and stannous chloride; (4) 4-chlorophthalimide, urea and stannous chloride; (5) phthalic acid, urea, stannous chloride, boric acid and ammonium molybdate; (6) phthalamide, urea, stannous chloride, boric acid and ammonium molybdate.  The products of the examples yield metal-free phthalocyanines by dissolving them in sulphuric acid or a mixture thereof with chlorsulphonic acid, and pouring the solution into water.  Di- and trihalogenphthalic acids and their derivatives are specified as additional starting materials. Specifications 322,169, [Class 2 (iii)], 390,149, and 410,814 also are referred to.

Abstract: 1,272,158. Making tampons. A. YAMAUCHI. 13 July, 1970 [19 July, 1969], No. 33927/70. Heading A5R. A method of making the main bodies of tampons comprises the steps of placing fibrous material folded into a wad in a forming machine, said wad having a withdrawal string (2), Fig. 1 (not shown) and a removably mounted central stem 7 of elliptical crosssection, compressing the wad by a pair of opposed flat lateral dies 4 having guides 3 and being activated by push-rods 9, then compressing the wad by a second pair of transverse dies 5 each having a concave recess of semicircular cross-section and being activated by a push-rod 10. The wad (1a) Fig. 1 (not shown) is compressed into a cylindrical shape. A pair of' upper and lower dies (6, 6') Fig. 5 (not shown), the upper die (6) having a central bore (8) receiving the upper end (7') of the stem. The lower die (6') having a hemispherical depression further compress the tampon. The last compression step may be carried out by stationary dies which define the upper and lower ends of the cylindrical body during compression of the body by the transverse dies 5. The stem 7 is subsequently removed and may be replaced by a specially prepared rod for insertion. The tampon on absorption of fluid, swells into an elliptical cross-section. Alternatively the stem may be introduced into the wad after the compression by the dies 4.

Abstract: 1280377 Fuel injection systems SOC INDUSTRIELLE DE BREVETS ET D'ETUDES 14 July 1970 [22 July 1969] 34143/70 Addition to 1207228 Heading G1N [Also in Division F1] The subject matter of this Specification is similar to that described in parent Specification in which there is disclosed an I.C. engine fuel and air supply arrangement comprising an air supply duct containing a downstream operatorcontrolled main throttle valve and an upstream auxiliary throttle valve arranged to open automatically and progressively as air-flow in the duct increases, and an electromagnetically actuated valve for controlling the quantity of fuel injected into the duct at a position downstream of the main throttle valve during a fraction of each revolution of a continuously rotatable member, said fraction being regulated to control the period of energization of the electromagnetically actuated valve and thereby the amount of fuel injected, in accordance with the degree of opening of the auxiliary throttle valve and thereby in accordance with air-flow. However, the present claims are concerned with an improvement in the arrangement, wherein between the rotary member and an engine-driven drive-shaft therefor, there is arranged means to modify, during operation, the angular position of the rotary member relative to said shaft to consequently control the moment of injection. The means comprises a differential gear arrangement, the housing of which is angularly adjustable in accordance with main throttle valve position or the suction downstream of the main throttle valve, to adjust the relative angular relationship. Thus the arrangement can allow the fuel injection to occur whilst the engine intake valves are open or closed, in accordance with engine load.

Title: Process for the production of pure ª-caprolactam from beckmann reaction mixture
Inventor: BAUER KURT
Filed: 1957-11-01
Abstract: Pure e -caprolactam is obtained from the neutralized reaction mixture from the Beckmann rearrangement of cyclohexanone oxime by sulphuric acid, by intimately mixing the two-phase mixture (consisting of an aqueous lower layer containing sulphates and a small quantity of lactam, and an organic layer containing lactam, some water and a small quantity of sulphates) with about 2-10 parts by weight of benzene, calculated on the lactam content of the mixture, separating the upper layer of the resulting two-phase mixture, distilling off benzene from this layer, and finally distilling off lactam.  The separated aqueous lower layer may be washed with benzene, which is then used for a further extraction of neutralized reaction mixture. The separated benzene layer may be washed with water or weakly acidified water prior to distillation of the benzene, and the wash water may be added to the reaction mixture of a fresh batch before or during the mixing with benzene.  Specifications 594,263 and 703,019 are referred to.

Title: Improvements in or relating to a safety shut-off valve
IPC: F15B21/00
Filed: 1954-11-26
Abstract: 760,462. Fluid-actuated valves. ROSS OPERATING VALVE CO. Nov. 26, 1954 [Dec. 9, 1953], No. 34324/54. Class 135. A safety shut-off valve device 11 for cutting off the flow of fluid in a working line 12, 13 between a fluid-actuated or other pressurereceiving device 14 and a control valve 15 when the pressure in the line reaches an equilibrium condition and for preventing further supply to the working line until the pressure therein has been substantially reduced comprises a valve member 26 operated by a fluid-pressure operated actuating member such as the piston 28 having a first fluid connection with the control valve and a second fluid connection with the pressurereceiving device 14, means such as the spring 34 which aids the pressure derived from the second fluid connection in closing the valve against the pressure supplied by the first fluid connection and a passage 49, 53 for interconnecting the second fluid connection with the first fluid connection when the valve is closed. In Fig. 2, the valve member 26 is integral with a piston 28 dividing a chamber 29 connected directly through a port 22 and the pipe 12 with the control valve 15 from a chamber 32 connected with the cylinder 14 through the line 13 and passages 39, 41, 42, 47 formed in the valve housing 18 and its cover 19. The control valve 15 has pressure and exhaust connections 16, 17 respectively. A spring-loaded relief valve 43 is arranged between the passages 42, 47. This delays the application of pressure to the chamber 32 and the consequential closing of the valve 26 until the pressure in the line 13 is sufficient to open the valve 43. When the line 12 is drained by the valve 15, a spring-loaded check-valve 48 opens to permit fluid to pass through passages 49, 53 to the chamber 29. The valve 26 is then held closed by the spring 34. The opening movement of the valve 26 is limited by a stop flange 37 on a stem 36 cooperating with a wall 38. The opening of a cyclically operated valve 55 will not affect the valve 26 once it is closed. Fig. 4 shows a modification having a diaphragm valve 67 co-operating with a tubular member 64 having a lateral port 62 connected to the line 13 and an end port connected through passages 74, 75, 76 and the relief valve 73 with a chamber 69 above the diaphragm. The diaphragm is spring-loaded and the chamber 69 above it is connected through passages 79, 81 and a check-valve 78 with an inlet chamber 63 open to the line 12.

Filed: 1957-11-05
Abstract: 846,778. Casting composite articles. OWENSCORNING FIBERGLAS CORPORATION. Nov. 5, 1957 [Nov. 21, 1956], No. 34470/57. Class 83 (1). Glass-reinforced metal articles are made by forcing metal under pressure into contact with the fibrous glass reinforcement. Glass fibres 21, Fig. 1, are drawn from a glass-melting tank 20, are coated with molten metal such as aluminium from an applicator 23, and are wound on a collet 24 into a preform of metal-coated glass 27, Fig. 4, which is placed in a centrifugal casting mould. The mould may be heated to melt the metal, or additional molten metal may be added. The metal collet itself may form part of the preform- and be melted during the casting operation. In a modification, Fig. 5, a tube 34 containing fibrous &c. glass reinforcement 35 is supported in a rotatable mould 31, in packing material 36. A counterweight 37 is provided. The mould is rotated, and metal is poured into the tube 34. In a further modification, Fig. 6, bare or metal-coated glass fibres are thrown on to a rotating table 44, which projects them against a rotating collector 45 to form a cylindrical package 47 of fibres. A metal flame spray gun 46 may direct molten metal against the interior of the pack. The pack may consequently be shaped, as by extrusion, rolling or pressing. In another modification, Fig. 7, the centrifugal casting mould 52 has internal screw threads 58 so that material is urged to the bottom thereof during rotation. In a further modification, Fig. 9; glass reinforcement in fibre or flake form is held in a mould 60, to which vacuum is applied, so that molten metal enters the mould from a bath 62. Alternatively, molten metal is forced under pressure into a mould containing glass reinforcement.

Abstract: 393,666. Sliding latches. PRESSED STEEL CO. OF GREAT BRITAIN, Ltd., Cowley, Oxford, and FERNBERG, E. B., 11, The Drive, Edgware, Middlesex. Dec. 12, 1931, No. 34534. [Class 44.] In a door latch of the kind having both inside and outside handles for operating the latch bolt and means whereby a movement of one handle locks the bolt against movement by the other handle, the inner and outer handles are movable about a common horizontal axis, and a movement of one handle about its axis in a direction opposite to its opening movement, locks the bolt against movement by the other handle without hindering the retraction of the bolt by the striker plate &c. directly engaging the bolt. In one form the latch plate 2 is actuated by a follower 51 carried by a U-shaped lever 16 fixed to a bush 14 on the outside of the lock body and extending round the edge of the window glass to bear on a bush 13 on the inside of the lock body. A lever 56 fixed on the bush 13 has a lug 57 engaging the lever 16, so that when the inner handle is turned clockwise, the lug lifts the lever 16 and causes the follower 51 to open the bolt. When the inner handle is turned in the opposite direction, a slot 59 in the lever 56 moves a lug 60 on a lever 61 into engagement with the follower 51 so that the latter cannot be moved by the outer handle to open the bolt. In the form shown in Fig. 8, the follower 39 operated by the inner handle has a lug 42 engaging a cam slot 43 in a lever 44 having a projection 45. When the handle is turned to retract the bolt 29, the lug 42 slides in an arcuate portion of the slot and the lever 44 is not moved, but when it is turned in the opposite direction, the lug moves the lever 44 and brings the lug 45 into the path of a lug 49 on the follower 46 operated by the outer handle, thus preventing retraction of the bolt by the latter. The inner handle and follower 39 are kept in locking position by a lug 50 on a lever 36 engaging the lug 42 on the follower.

The purity of a gas is tested by testing the dependency of Townsend discharge on voltage. As shown a pair of electrodes 12 half surrounding a fluorescent tube 11 under test for the purity of its gas-filling is fed with an alternating voltage, the amplitude of which increases with time. At a voltage characteristic of the purity of gas-filling, a Townsend discharge closes the circuit between the electrodes and a pulse amplifier 2 delivers an output pulse of duration corresponding to that of the Townsend discharge. This pulse is evaluated by a pulse-counting technique to determine whether the tube 11 is good or bad. The tapping point of voltage divider 52 is controlled by a squarewave pulse generator 42 forming part of the evaluating circuitry.
