Title: Improvements in or relating to carburettors for internal combustion engines
IPC: F02M3/12
Filed: 1926-08-31
Abstract: 281,027. Wade, H., (Thelma Carburator Co. Soc. Anon.). Aug. 31, 1926. Spray carburettors.-The carburettor is of the type in which the fuel needle-valve is connected to a suction-actuated air valve, and comprises a fuel inlet 13, controlled by a valve 14, and leading to a nozzle element 10 which contains a spring-loaded ball valve 15 for separating the fuel inlet from a chamber 18 having a pilot nozzle 19. and a needle valve 20 - 22 for controlling the fuel flow to main orifices 11. The needle valve is connected to a, suction-actuated air inlet valve 24 which normally rests on a spring buffer 29, and the air inlet is flared both inwardly and outwardly at 27, 28. The pilot nozzle 19 faces a tube 31, which communicates through passages 32, 33 with the induction passage 34 on the engine side of the throttle valve 35. The initial lifting of the valve 24 by suction opens the valve 15 and permits an excess of fuel to flow to the chamber 18 and pilot nozzle 19, but the cylindrical part 20 of the needle valve cuts off the fuel to the orifices 11. On the valve being lifted further, the conical part 21 allows fuel to flow in increasing amount to these orifices. Should a. back-fire occur, damage is prevented by the valve 15 being closed, and also by the valve 24 being forced beyond its seating into the flaned portion 28 so as to provide an outlet for the gases. Additional air is admitted through apertures 40 controlled by an apertured ring 38 actuated from the throttle valve spindle by a slotted arm 43 and a pin 44.

Title: Improvements in or relating to manufacture of benzene hexachloride
Inventor: MILLER LEO ANTHONY
IPC: C07C17/02
Filed: 1952-08-27
Abstract: Benzene hexachloride is made by a continuous process by adding to benzene a quantity of chlorine insufficient to cause the formation of solid benzene hexachloride in the system by maintaining the density when corrected to 20 DEG  C. as described below, at less than the value given by d = 0.8922 + 0.002377, where d is the density of the solution corrected to 20 DEG  C. and T is the solution temperature; and passing the solution of chlorine in benzene through a tube where it is irradiated with actinic light.  The density of the solution corrected to 20 DEG  C. is obtained by measuring the actual density at any given temperature <PICT:0736696/IV (b)/1> and subtracting the integrated correction factor given by the accompanying graph (Fig. 5); the corrected density should be less than the value obtained for d in the above equation to avoid formation of solid benzene hexachloride.  The preferred conditions comprise forming a solution of chlorine in benzene which may suitably be recycled benzene containing from 2 to 15 per cent of benzene hexachloride, flowing the solution in a stream with a hydraulic radius of 0.5 to 1.5 inches, for from 5 to 20 minutes at a preferred temperature of 20 DEG  to 80 DEG  C. while maintaining the solution at a density corrected to 20 DEG  C. of 0.85 to 1.03 grams per c.c.  Apparatus for carrying out the invention, described with drawings, comprises an elongated conduit of hydraulic radius not exceeding 1.5 inches, distributing means whereby a cooling liquid is distributed uniformly over the light transmissive walls of the conduit and light sources, preferably fluorescent tubes, aligned parallel with the conduit to give 10 to 20 watts per foot of conduit length.  An example is given.

Abstract: 616,700. Cathode-ray tubes. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 22, 1945, No. 21538. Convention date, April 11, 1942. [Class 39 (i)] In a television transmitting tube of the low velocity electron scanning beam type in which spiral motion of the electrons of the beam arises in a longitudinal magnetic field due to misalignment of the cathode, the forces causing such spiral motions are compensated by a further constant magnetic or electrostatic magnetic field having lines of force normal to the lines of force of the longitudinal magnetic field. As shown, an electron gun 6 is fortuitously misaligned relatively to the longitudinal magnetic field due to coil 17, and oppositely disposed compensating magnetic coils 19 are orientated according to the direction of misalignment. Instead of coils 19, permanent magnets may be used. The compensating field may be electrostatic, produced by the plates 25 to 28, and may be rotated by varying the potentials on these plates. Both coils 19 and plates 25 to 28 may be utilized. The invention may be applied to a tube having a target of the photo-voltaic kind or image grid kind in which the grid controls the passage of an electron beam through the target. Specification 542,219 is referred to. The Specification as open to inspection under Sect. 91 comprises also the application of compensating fields to a tube comprising electrostatic beam lifting plates and utilizing secondary emission derived from the beam returning from the target. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in machines for shocking grain
IPC: A01D75/06
Filed: 1923-08-27
Abstract: 221,936. International Harvester Co., and Waddell, W. Aug. 27, 1923. Shocking-machines.-Sheaves are delivered in pairs from the binder-deck to the shock-forming receptacle by a member that spreads the butts of the sheaves during their passage to the receptacle. The shock-forming receptacle 23 is pivoted on a shaft 22 and is actuated to swing upwardly and rearwardly to deposit a completed shock by a crank 24 on a shaft 26 adapted to be coupled through an arm 30 and gravity latch 29 to an arm 28 pivoted on the shaft 26 and connected by a link 31 to a crank 32 on the knotter shaft 20. A shaft 34 is mounted in brackets at the end of the receptacle and is normally held by a spring to maintain tines 33, carried by the shaft, upright. These tines hold the sheaves in the receptacle against longitudinal displacement. The sheaves are discharged in pairs from an extension 80 of the binder-deck on to the sheaf-delivery member 38 which is secured to a shaft 39 and which carries at its outer extremity two pivoted arms 72 having upwardly extending tines 75, 76. Tines 88 extending inwardly from the supporting frame for the sheaf-delivery member also serve to support the sheaves. The arms 72 normally tend to diverge under the tension of springs 73 but while the delivery member is in receiving position are held together by cams 79 secured to the frame. When the pair of sheaves is deposited on the delivery member a trip device 54 is released and the shaft 39 clutched to a constantly-rotating shaft. The delivery member 38 swings upwards, the arms 72 opening as they rise and thus causing the butts of the two sheaves to diverge as they are swung over to the shock receptacle. A divider 56 is pivoted on brackets secured to the shock receptacle and is normally held by springs in operative position to spread apart the sheaves at their bases as they are delivered into the receptacle. The divider comprises a shield portion 66 and an upper loop portion 67. When the sheaves in the receptacle have reached a predetermined height a binding device is tripped into operation and a band is tied round the shock; the crank 24 is then operated to raise the receptacle 23 and the shock deposited, the springs controlling the tines 33 and the divider 56 yielding till the shock is clear of the machine.

Patent GB-1109084-A (GB)
Title: Treatment of aluminium alloy surfaces
IPC: C09K3/14
Filed: 1965-05-24
Abstract: In a method of forming a low friction finish on the surface of a high-silicon aluminium-base alloy article, aluminium is preferentially removed from the surface to expose particles of silicon protruding above the aluminium surface and the protruding particles are mechanically smoothed.  In an embodiment, the surface of the alloy is lapped to a rough finish using, for example, a mixture of aluminium oxide or silicon carbide and a mineral oil. Aluminium is then removed by lapping with a suspension or dispersion of finely divided elementary silicon in a mineral oil, and honing the alloy surface therewith to produce initially an attack on the aluminium alloy matrix, so removing the aluminium, and forming a surface in which the silicon crystals protrude above the alloy surface.  Continued honing removes the sharp edges of the protruding silicon and provides a lowfriction glaze finish.  The aluminium may be removed chemically, such as by etching with acid; and the glaze finish may be effected by the application of a metal surface under pressure, as for example by the reciprocating of a piston in a cylinder.  The alloy may contain from 6-20 per cent by weight of silicon and may specifically comprise 16-18 per cent by weight of silicon, 4.2-4.9 per cent copper, up to 1 per cent iron, 0.45-0.65 per cent magnesium, 0.08-2 per cent titanium, up to 0.1 per cent manganese and the balance aluminium.
