Title: Improvements in carburettors for internal combustion engines
IPC: F02M19/08
Filed: 1935-07-18
Abstract: 457,669. Spray carburetters. GLADWELL, A. W. D., Ampton Street Works, Gray's Inn Road, London. July 18, 1935. Nos. 20475 and 20476. [Class 7 (iii)] A spraying nozzle, mounted coaxially in a mixing chamber and fed with fuel through two submerged jets connected in parallel, is adapted to receive air through a slowrunning device which can either draw fuel from a well, fed by the two jets, at the base of the nozzle and deliver the usual small quantity of mixture to one or more holes in the side of the throttle chamber adjacent the throttle valve when closed or can allow air or mixture to pass in the opposite direction to the well to regulate and emulsify the fuel when the throttle is sufficiently opened to deplete the well of fuel. A float chamber k connected by a swivelling union to the carburetter body a supplies fuel through a passage l<1> to a submerged nozzle i<1> in a vertical pocket e<1> and through a passage l<3>, l<2> having several bends to a second submerged nozzle i<2> in a pocket e<2>. The nozzles supply a common passage j formed in a cross-member b in the body a which is inclined at 45‹ to the vertical and the cross-member b supports the pockets e<1>, e<2> and a central vertical pocket e containing a slow running nozzle x<1>. The base of this pocket forms a well e<3> feeding a main nozzle c having a heated central tube c<1>, as described in Specification 451,726. This nozzle is disposed axially in the chamber a and discharges into a Venturi m having displaceable bolts m<2> as described in Specification 450,495. A controlled quantity of air entering by ports d<2> at the top of a tube d<1> carrying the slow running nozzle x<1> passes during such running through ports d<4> and a passage f in the wall of the body to outlets g, g<1> adjacent the throttle valve. During normal running, fuel, which has stood around a ribbed portion d<1> of the tube d<11> nearly to the level of an additional air inlet x in the pocket e is withdrawn from the pocket and the well e<3> and aerating air flows in through the ports d<2> and inlet x assisted by some mixture drawn down the passage f. The body a is secured to a throttle chamber n having flanges n<1>, o at 45‹ to one another to adapt the carburetter for attachment to a vertical or horizontal flange.

Title: Chemical nickel plating method
IPC: C23C18/16
Filed: 1958-06-26
Abstract: In a method of chemical nickel plating employing a stabilised solution of the nickel cation-hypophosphite anion type, (a) a plating tank is used which is made of steel having a chromium content above 10% and which is periodically de-activated by treatment with dilute nitric acid, (b) the plating solution is maintained in the plating tank at a temperature not in excess of 95 DEG C., and (c) the plating solution is regenerated in respect of its stabiliser at least.  The stabiliser may comprise heavy metal ions (i.e. ions of lead, copper, bismuth, tin, selenium, tellurium, tungsten, thorium, titanium, zinc, manganese or rhenium), an inorganic thio-compound e.g. thiosulphate, or an organic thio-compound, e.g. potassium ethyl xanthate, the solution preferably being formulated in respect of stabiliser using the method of Specification 886,737.  Specifically described is a continuous plating system of the type disclosed in Specification 785,693 in which two stainless steel plating tanks are provided so that while one is being de-activated the other is available for plating.  Specifications 761,062, 761,567, 785,694, 785,695, 785,696, 786,175, and 821,763 also are referred to.

IPC: B04B11/08
Filed: 1938-07-12
Abstract: 516,611. Centrifugal separators. AKTIEBOLAGET SEPARATOR. July 12, 1938, No. 20630. Convention date, Aug. 5, 1937. [Class 23] The distributor 2 of a centrifugal separator bowl has a number of wings 3 cast integral with it and which form a number of channels for the liquid supplied through radial jets at the bottom of the inlet pipe 1. The wings extend inside the normal liquid level in the distributor, and are machined to fit tightly on the bowl nave 4. The lower part of the wings are advantageously connected to a disc 7 which may have a conical extension 8 to fit the nave and to form the inner wall for the channels. The arrangement is shown used with a disc pack 6 having holes 5 but it may be used with unperforated discs, or in a bowl without a disc pack.

Filed: 1918-12-16
Abstract: 136,617. Godsal, P. T. Dec. 16, 1918. Breech actions, sliding breech-block.-Relates to breech actions of the type described in Specifications 22003/02, 1540/14, and 18021/14, having a breech-block capable of rotation in a carrier slidable longitudinally, and consists (1) in mounting the striker and its spring in the rear of the carrier and an independent firing-pin in the block; (2) in mounting on the striker a cocking- piece having a bent directly beneath the carrier. (3) in mounting on the carrier a hood containing a safety-catch, and (4) in mounting in the carrier a spring plunder adapted to hold the breechblock against rotation except when it is in the locking position. In the form shown, the striker 3 and its spring 4 are housed in a boring in the carrier 2, the protruding end of the striker carrying a cocking-piece 5 with a bent 6 running in a groove below the carrier 2 and engaging the sear 7. A nose 12 on the striker, adapted to enter a recess in the breech-bolt when this is locked, serves to check the striker before it reaches the firing-pin 28 if the bolt is not properly locked. A hood 15 mounted on the carrier is held in position by the hand-lever 11, and encloses a safety-catch 18 rotatable by a thumb-piece 20 into any one of three positions in which it is held by a spring catch 27. In the central position of the thumb-piece, the stop 26 arrests the striker before it reaches the firing-pin 28; in the left-hand position, the safety obstructs all movement of the striker; and in the right-hand position, the cutaway portion 24 permits the striker to go forward to fire the gun. In addition, a small metal ring may be sprung on to the shaft of the striker in rear of the carrier when it is desired permanently to prevent the striker from reaching the firing- pin. A spring plunger 34, Fig. 3, in the carrier 2 is adapted to engage the breech-bolt and hold it against rotation until the bolt reaches the locking position, when the plunger strikes the righthand jaw of the breech and is disengaged from the bolt. A bolt stop 31 is mounted on the side of the body 1, and may be sprung aside to permit the passage of the bolt when assembling.

Abstract: 937,094. Gas turbine plant. GARRETT CORPORATION. June 17, 1960 [June 25, 1959], No. 21450/60. Class 110 (3). [Also in Group XXVII] An internal combustion engine turning gear includes a motor 21 arranged to drive the engine and to be driven by gas from the outlet of either a compressor 5 or a combustion unit 15. The turbine 8 is driven by the exhaust of the combustion unit 15 the inlet of which is connected to the outlet 4 of the compressor. As shown the motor 21 is a turbine. The same starting system could be employed for any number of cylinder blocks and employing any number of turbochargers. The starting turbine could be fed from a single turbo-charger or from a number of turbo-chargers. Alternatively each engine could have its own starting turbine and turbo charger and suitable ducting could be provided to enable the output of several or all of the turbo-chargers to be connected to the starting turbines in turn. It would be possible to place the starting turbine 21 in series with the turbo-charger turbine 8. For simplicity the starter 13 is shown as a manual device but it may be electrically, pneumatically or hydraulically driven. The clutch 14 may be a mechanical, electrical or pneumatic device. The valves 18 and 24 may if desired be operated electrically, pneumatically or hydraulically. A spill valve 31 is controlled in such a way as to maintain a constant manifold pressure over a range of operation of the engine. This control is facilitated by the selection of a small nozzle area for the turbo-charger turbine 8.
