Title: Bowling pin distributing mechanism
IPC: A63D5/08
Filed: 1963-05-14
Abstract: 1,046,932. Bowling alleys. AMERICAN MACHINE & FOUNDRY CO. May 14, 1963 [May 18,1962], No. 19162/63. Heading A6D. A pin distributer assembly for a bowling alley installation comprises a boom-like conveyer VIII adapted to swing horizontally to and fro to convey and distribute pins in the requisite triangular array to a pin storage assembly IX mounted above the pins potting table of the installation. The distributer boom comprises two parts 4 and 6 each comprising a pair of endless belts trained over driver pulleys, and is reciprocated about pivot shaft 2 by motor 116 acting through crank 20 and link 122, the outer end of part 4 of the boom being supported by means of feet 38 movable over track 42 fixed to the framework of the alley. Pins are discharged from a pin elevator to a hopper 34 from whence they are fed by wheel 32 on to part 4 of the distributer and conveyed to part 6 thereof. Part 6 of the distributer comprises four cams LRC, RRC, LFC, RFC which normally lie out of contact with pins passing along the distributer, but which are operable individually by solenoids to discharge pins to either side and to the front or rear of the part 6 of the boom. Alternatively, if the cams remain inoperative pins are conveyed the full length of the distributer and are discharged off the forward end thereof. Pin-actuated switches mounted on the boom are arranged to be operated each time a pin is discharged therefrom. The drive to the boom and the operation of the cams thereon is controlled so that the boom moves step-by-step over the storage unit IX and so that pins are discharged sequentially to all the pin storage compartments 1-10 as marked on Fig. 2, the control being effected by switches operated by cams DI mounted on the output shaft 118 of the motor 116, and by the pin-actuated switches on the distributer boom, Drive to the distributer boom is automatically switched off when the pin storage assembly is full. The above distributer is preferably used in combination with a pinstorage unit of the type described in Specification 1,046,933 and with a pinspotting table of the type described in Specification 1,046,934.

Abstract: 1432833 Chromatographic analysis BRITISH PETROLEUM CO LTD 18 March 1974 (24 April 1973] 19266/73 Heading B1H [Also in Division F2] A valve for use in chromatographic analysers, e.g. for estimation of organic carbon in water, comprises a flexible tube 2 located between a pair of in-line connectors 3 to define therewith a continuous flow passage through the valve. When a pressure liquid or gas is delivered into chamber 1 via port 4, the tube collapses to close the passage. The tube may be circular or elliptical and formed of rubber or plastics. Samples for analysis are introduced into an analyser via a hypodermic needle 6 passed through the passage. The pressure in chamber 1 is relieved when the needle is inserted into or withdrawn from the passage. The valve may be actuated automatically by mounting the syringe on a sliding holder so that downward movement of the syringe activates the applied pressure. Alternatively, the applied pressure may be used to move the syringe and needle.

The surface may be concave as shown with, above the loop, a convex portion 15 over which the filament is drawn to increase tension before wind-up. In other constructions, a plurality of surfaces, which may be concave or flat, are arranged in cascade below each other, a convex roller then being used over which to pass the filament to increase its tension. The wind-up station may also be vertically above the surface whereby gravity supplies the additional tension.

Title: Improvements in processes and apparatus for depositing concrete and the like under pressure
IPC: B65G53/30
Filed: 1924-08-19
Abstract: 222,092. Leicknam, G. J. M. Sept. 19, 1923, [Convention date]. Casting and moulding in situ.-For filing up interstices, fractures, &c., and for spraying plaster and the like, a cement gun is used connected to a water-pressure supply, the apparatus being operated in such a manner that each charge of material is ejected in a series of gushes caused by opening and closing the delivery valve D so that before each gush the pressure rises to the pressure of the pump. The gun T is filled with the filling material and the air-escape valve t is then opened. Water pressure is supplied by a pump P or other supply through a valve A, another valve B allowing the discharge of the material and water to the injector pipe R, I<1>. Pressure gauges may be employed to register the water pressure and fall of pressure, and an auxiliary pressure pipe a may be employed to assist discharge. In a modification, Fig. 4, the material is fed continuously from a hopper S by a screw to the outlet K, water pressure being supplied through pipes l or through a central aperture of the screw. In a further modification, the screw chamber may be disposed at right-angles to the pressure-supply chamber. In both these modifications, pellets of the charge are fed into the throat q blocking this throat and causing the pressure to rise before the pellet is discharged, thus delivering the material as before in a series of gushes.

Abstract: 690,220. Snap-action switches; thermal switches; pressure actuation of switches. RANCO, Inc. July 27, 1949 [Aug. 3, 1948], No. 19743/49. Class 38 (v) A snap-action switch comprises a slotted spring blade 34 carrying a contact 133 which co-operates with a fixed contact 132, an inflexible toggle link 140 and a U-shaped blade spring 41 disposed within the slot in the blade 34, a further slotted blade spring 131 having an arm 136 with a slot 56 through which the link 140 projects, and a fulcrum 112. In the construction shown, when a push-button 115 is depressed, the spring 131 pivots about its fixed end and the end of the slot 56 in bearing against the link 140 causes the link to pivot about the abutment or fulcrum 112 until the spring toggle 41, 140 is moved over its dead-centre position, when the blade 34 is snapped up to close the contacts. When the button 115 is released the spring blade 131 restores the button and moves the toggle back over its dead-centre position to open the contacts. The blade spring 34 is initially tensioned to provide a high contact pressure whilst the toggle is moving through its dead-centre position. Fig. 1 (not shown) illustrates the application of the switch to a pressure or temperatureresponsive control apparatus, the subject matter relating to this control apparatus forming the subject of the divided Specification 690,263. The Specification as open to inspection under Sect. 91, also describes a casing for the apparatus of Fig. 1; this subject-matter does not appear in the Specification, as accepted but forms a part of Specification 690,263.

Switches, quick-action.-Ironclad switches of the kind having a cranked main spindle with a main spring to give a quick-action have, in addition to a lost motion between the handle and the spindle, a lost motion between the pivoted blade contacts and the spindle. In one type of twopole switch fuse, Figs. 2, 3, and 7, the handle b<1> operates a spindle b which is controlled by a mainspring c. To the pivoted blade contacts e are fixed blocks g, channelled to receive metal rods h, h<1> insulated from them. A link n provides the lost motion, one end being loosely mounted on the spindle b, the other being of a special contour and held in engagement with the rods h, h<1> by a secondary spring o. In the "on" position, Fig. 2, the tangs n<1> of the link n engage the rod h<1>, and when the handle b<1> is moved over to open, the edges of the links n move along h<1> until the latter is engaged by the shoulders n<3>. Just as the contacts are about to separate, the spring c is at maximum tension, and the switch is finally rapidly opened, Fig. 3. To close, the shoulders n<2> engage the rod h to thrust it forwards and downwards until the dead-centreposition of the spring c is reached, whereupon rapid closure is effected. If the switch is put on a wall or ceiling, the part n<4> of the plate n holds the contacts e in the " off " position.
