Abstract: 421,190. Coin-freed games apparatus. BARTRAM, R. L., and PERRY, F., 163, Promenade, Blackpool. June 17, 1933, No. 17298. [Class 132 (ii)] [See also Group XVIII] Games apparatus comprises a board oscillatably supported in a casing and controlled from outside the casing to cause balls to run into apertures in the board, the bottoms of the apertures being normally closed by a member which can be moved to release balls contained in the apertures, such balls then passing to a device which can lift them on to the board. The playing board 5 has a surround 6 and is situated beneath a glass plate 2. The board is provided with apertures into which balls are rolled by tilting the board. The apertures are normally closed at the bottom by a plate 7 having apertures which, when the plate is moved relatively to the board allow the balls to fall through on to an incline 9. The plate 7 is moved by turning a knob 29 and coin-freed shaft 27 acting through levers 31, 33. The balls pass individually from the incline 9 into a cup 12 secured to an arm 13 rotated by a knob 15 to bring the cup above the playing board. The board can be tilted in any direction by a handle 49 pivoted to a rod 48 having a head 46 engaging a tube 45 secured to a hemispherical projection 40 on the bottom of the board. The projection 40 is supported by four balls 41. In modifications, the board may be rocked by a plurality of electromagnets, one beneath each corner of the board, the score may be indicated electrically by circuits closed by the balls passing into the holes in the board, and the said circuits may be arranged to release or deliver a prize. Coin action, weight.-The shaft 27 is released by inserting a coin in a slot 18, the coin passing down a shoot 19 and depressing a lever 21 pivoted at 22, a pawl 23 thus being removed from a ratchet wheel 25 on the shaft 27.

Title: Control valve for hydraulic presses
IPC: F16K17/00
Filed: 1942-12-08
Abstract: 561,978. Valves. TOWLER, J. M., and TOWLER, F. H. Dec. 8, 1942, No. 17444. [Class 135] A valve device adapted to be interposed between a control valve and an hydraulic press or hydraulic power cylinder is arranged to restrict the release of pressure to exhaust until such time as the pressure of liquid in the press cylinder has fallen to a predetermined minimum. In the form shown in the Figure, a valve piston f with a tapered flat o is slidably mounted on the reduced part e of a plunger a and is normally held against a shoulder on the plunger by a light spring n. A piston h detachably secured to the plunger is formed with a flat m to provide a restricted passage connecting a chamber l on the outer side of the piston with a chamber k provided with a connection d leading to the press. The plunger is loaded by a spring p and an adjustable stop q is provided to limit the movement of the valve f so that the flat o forms a restricted passage connecting the chamber k to a connection c leading to the control valve. When the control valve is operated to admit fluid pressure, the valve f opens againstthe action of the spring to permit a free flow to the pressure. As pressure builds up in the press cylinder, pressure seeps into the chamber l, moving the plunger against the action of the spring, When the control valve is put to exhaust the valve f immediately closes and exhaust takes place through the restricted passage o. As the cylinder pressure falls, the plunger gradually moves back to its original position gradually increasing the area or decreasing the length of the passage o until finally the valve is opened fully to allow a free exhaust.

Abstract: 1,263,246. Blasting. ABRASIVE DEVELOPMENTS Ltd. 13 May, 1969 [16 April, 1968], No. 17774/68. Heading B3D. Apparatus for treating workpieces, e.g. by abrasive blasting, comprises a cabinet into which workpieces may be introduced, a conduit having one end open to atmosphere and the other arranged to direct air and treatment material at the workpiece in the cabinet, means to introduce treatment material into the conduit and to withdraw air from the cabinet, the air and material being caused to impinge on the workpiece solely by the removal of air. The material may be abrasive, either in a dry form, or in the form of a slurry with water, and which may contain chemicals such as a rust inhibitor and/or a mould release agent. A cabinet 10 contains means to support a workpiece; the means may move the workpiece, e.g. rotate it or move it through a given series of positions. The lower part of the cabinet is formed as a sump 11 connected by a pipe 12 to a first cyclone 13 connected to a second cyclone 14 connected by a pipe 15 to suction means 100. The lower end of the cyclone 13 delivers through an upper hopper 16, a middle hopper 17 and a lower hopper 18 into a primary air conduit 19 having one end 20 open to atmosphere, the other end opening within the cabinet 10 via a nozzle 21. The lower ends of the upper and middle hoppers 16, 17 are provided with flap valves 22, 23 each of which opens and closes in dependence on the difference in pressure between the two hoppers which it separates and on the weight of any material acting on the valve; the middle hopper is alternately placed at atmospheric pressure or at suction pipe pressure via a pipe 24 either as described in Specification 1,070,233 and by the automatic valve as described in Specification 1,246,132. When the suction means 100 is started, primary air is drawn into the cabinet along the conduit 19 and entrains material at 25 from the hopper 18. The material is directed by the nozzle 21 at the workpiece. The cabinet is capable of being completely sealed except for the inlet conduit 19 and the outlet pipe 12. Abrasive impinges on the workpiece and then falls into the sump 11 whence it is returned to the first cyclone 13 wherein reusable abrasive is separated from dust and detritus, the latter passing to the second cyclone 14 and to a dust-box 26. The reusable abrasive passes from the first cyclone 13 through the hoppers 16, 17, 18 to be entrained again at 25 in the primary air stream. Apertures 27 in the conduit 19 immediately outside the cabinet 10 allow secondary air to enter. This enables the speed of the primary air stream to be kept slow to minimize wear, except adjacent the nozzle when the air stream will be accelerated.  The cabinet may have an air lock to enable workpieces to be introduced into and removed without completely destroying the vacuum.

Abstract: 939,765. Production of hydrogen and carbon monoxide. M. W. KELLOGG CO. May 18, 1961 [May 19, 1960], No. 18127/61. Drawings to Specification. Classes 1(2) and 32 A process for the production of hydrogen and carbon monoxide comprises introducing a hydrocarbon feed and a combustion-supporting gas into an externally heated partial combustion zone maintained at above 2500‹F. by burning an auxiliary fuel at a higher temperature in a burning zone maintained in indirect heat exchange with the combustion zone, said combustion-supporting gas containing at least sufficient total oxygen to satisfy the requirement for conversion of said hydrocarbon feed to hydrogen and carbon monoxide, which are recovered from the combustion zone. Flue gases, at a higher temperature than the combustion zone, may additionally be recovered from the burning zone. The combustion zone is preferably maintained at 0-500 p.s.i.g. and 2500‹-3000‹F. The feeds to the combustion zone may be preheated, at least in part by indirect heat exchange with the flue gases from the burning zone. By employing air as at least a part of the combustion-supporting gas and subjecting the products from the combustion zone to a shift conversion, a gas containing nitrogen and hydrogen suitable for use in ammonia synthesis gas may be obtained. Suitable combustion-supporting gases are mixtures of air and steam, oxygen and steam, and oxygen and carbon dioxide. The gas mixture product may also be employed to reduce iron oxide to sponge iron.

Filed: 1917-12-08
Abstract: 112,932. Soc. Generale des Freins Lipkowski. Jan. 26, 1917. [Convention date]. Fluid-pressure.-In an accelerator for air brakes of railway vehicles &c. adapted to repeat its working at each partial successive application of the brakes, and in which the successive reduction in train-pipe pressure due to local venting diminish in intensity, the accelerator comprises a slide valve C, Fig. 1, actuated by a piston B subjected to train-pipe pressure at A, and at the other side to the pressure in a reservoir D, two venting reservoirs E, F being provided. Fig. 1 shows the release position, the reservoirs E, F being exhausted at I. When train-pipe pressure is reduced, the valve moves to the position shown in Fig. 2, and the train-pipe vents into both reservoirs, after which the valve is returned by the spring R to a lap position, Fig. 3, in which the reservoir E only is exhausted, so that, for successive applications of the brake, venting into this reservoir E only is possible. The Specification as open to inspection under Sect. 91 (3) (a) describes a modification in which the reservoirs E, Fare dispensed with. and two slide valves C<1>, C<2>, Fig. 4 (cancelled), and two springs R<1>, R<2> are used. In an application of the brakes the valve C<1> first moves to the right against the pressure of spring R<1>, allowing the train-pipe to vent the atmosphere at G<1>; but as the pressure reduction increases. the second spring R<2> is compressed and the valve C<2> moved to cut off the exhaust G<1>. The valves then return to a lap position, and finally to the running position shown, and the action is repeated for successive applications. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to a process for removing superficial oxide coatings from metal particles
IPC: C23G5/00
Filed: 1949-07-11
Abstract: Metal powders are cleaned of superficial oxide coatings by heating the powder in a reducing atmosphere together with a small proportion of high boiling point completely volatile substance which is chemically stable under the conditions of heating, so that the substance distils off during the reduction process to prevent sintering of the powder.  0.3 to 2 per cent of a hydro-carbon, such as mineral oil, polybutene or paraffin may be used as the volatile substance and the reducing atmosphere may be pure hydrogen, dissociated ammonia or cracked illuminating gas. Heating may be effected at 350-650 DEG C in the case of copper, at 700-850 DEG C in the case of iron, and at 400 DEG C in the case of copper-lead powders.  The process may be a batch or a continuous process and when the volatile substance is a solid or viscous liquid, it may be diluted or dissolved in a volatile solvent.
