Abstract: 241,987. Anthony, W. C. July 29, 1924. Scraping-appa.ratus.-In a self-contained and self-propelled shovelling-apparatus the shovel E is mounted by means of a truck D upon a track C rigidly fixed by a framed structure B upon the engine A<1> of an automotive tractor which actuates and controls the shovel for shovelling, hoisting and dumping. The shovel E is positioned for the various operations solely by differences in the inclination of the parts C<2>, C<3>, C' of the track, the shovelling being effected by a forward movement of the tractor as a whole and the hoisting being performed by a cable V<3> which is wound round a drum V<2> actuated through gearing by the tractor engine. The shovel is assisted in its return from the dumping position by a spring-controlled structure I<1> which is displaced by the rising shovel, and by a weight F mounted upon the shovel. For controlling the movement of the winding-drum V<2> a friction clutch T<8>, T<17> and a brake U are provided, the clutch and brake being actuated by a cam X' mounted upon a sliding shaft X and so disposed that the clutch and brake are actuated by a single movement of the control lever G<1> and shaft X. A stop H<1> is provided on the cable V<3> so as automatically to arrest the shovel at a predetermined position in its movement along the track C by contacting a lever H thus operating the shaft X. The braking- mechanism comprises a shoe U with lining U<1> formed concentrically with the clutch housing T<7> and having lugs U<2> upon which springs U<5> press so as normally to hold the shoe locked upon the housing T', the shoe U being pivotally mounted upon a shaft U<7> and having a projecting arm U<11> resting upon the cam X'. The winding-drum V<2> is provided with a projecting socket Y of varying internal diameter in which is retained a tapered enlargement or cap V<7> and the cable V<3>, the socket Y having a slot in its side to allow the cable to be passed laterally therein and a curved cushioning-track Z so merged into the socket as to prevent kinking of the cable.

IPC: B03C3/02
Filed: 1973-04-16
Abstract: 1402785 Treating charges A S KING 16 April 1973 [28 April 1972] 18209/73 Heading F1B Apparatus for treating a carburetted mixture of air, water vapour and droplets of an atomized volatile fuel comprises a heat exchange structure (defined within wall 30), means (electrode wall 30 and electrode 44) to establish an electrostatic field within the structure, an inlet 12 to admit the mixture into the field to assist vaporization of the fuel droplets, an outlet 18 to allow the air and fuel vapour to leave the structure and means to prevent water condensed from the mixture during vaporization of the fuel droplets from leaving through the outlet 18. The mixture entering from the inlet 12 follows a helical path formed by heat exchange vane 50 between electrodes 30, 44 and then passes between electrode 44 and tube 46 and through tube 46 to the engine inlet manifold 20. Vaporization of the fuel droplets (stated to be encouraged by the relaxation of the surface tension of the droplets by the electrostatic field) causes vane 50, and wall electrode 30 to be cooled, thereby helping to condense water vapour. The water is removed via a line 58 to a reservoir 60 where any condensed fuel can be separated for return to the carburetter. A disc (22) between inlet pipe 12 and conduit 14 has an opening (24), Fig. 2 (not shown), smaller than opening 26 in a gasket 28 so that in use the pressure is reduced in the chamber. In another embodiment, Figs. 3 and 4 (not shown), the electrodes are in the form of flat plates (84), (88) and a plate (95) prevents condensed water droplets from passing to the engine inlet manifold 20.

Title: Improvements in or relating to the production of cast iron castings by the centrifugal process
IPC: B22D13/00
Filed: 1927-07-15
Abstract: 285,721. Newton, Chambers, & Co., Ltd., and Hurst J. E. July 15, 1927. Casting processes; casting-machines. - Castiron cylindrical castings, such as cylinder liners for internal-combustion engines and piston valve liners for locomotives, are made by the centrifugal process, the silicon content of the metal being adjusted and the casting being rapidly cooled from a temperature almost immediately below its solidification point by means of an air blast, moistened or otherwise, applied to the inner surface, so as to obtain a sorbitic structure in order to render the article more resistant to wear, impact and volume changes on heating and to increase its tensile strength. The blast mav be cut off when the desired structure is obtained or may be continued until the casting is cool. The proportion of silicon is kept low so as to aid in obtaining this structure and is dependent on the average thickness of the casting and on the thermal conductivity and temperature of the mould material. When making a casting from a quarter of an inch to three inches in thickness in a rotating metal mould, the percentage of silicon varies from 2.25 to 1.25, and for casting in a sand or loam mould from 1.5 to 0.5. In casting a cylinder of one inch thickness in a rotating sand or like mould 1 to 1.25 per cent of silicon is used, an air blast of from 20 to 60 pounds pressure is introduced through a valvecontrolled nozzle until the casting has cooled from the solidification point to between 700‹ C and 760‹ C. For thicker castings and for castings containing more silicon or produced in hot metal moulds, the air blast may be moistened with water or oil, such as a light mineral oil, e.g., by using an injector nozzle, so as to effect a quicker cooling.
