Title: Improvements in or relating to fluid-actuated vehicle hoists
IPC: B66F7/04
Filed: 1949-06-28
Abstract: 659,242. Vehicle hoists; winches. DAVIES, A. R. (Soc. per Azioni Emanuel). June 28, 1949, No. 16523. [Classes 78 (iii) and 78 (v)] In a vehicle hoist in which a platform is hauled up four corner guide posts by a hydraulically operated winch, a safety device is provided automatically to stop hoisting if any part of the vehicle projects sufficiently to foul a fixed part of the hoist. The vehicle supporting members 25 are secured to cross members 21, 22 which slide on guide posts 1 and are secured to lifting cables 18, 181 and 19, 19<1> wound on drums 17, 171 secured to a shaft 14. This. shaft carries a drum 7 which is connected by a cable 6 with the piston 4 of a ram 3 in such a manner that retraction of this piston effects lifting movement of the members 25. The ram is controlled by a slide valve 12 which is movable by a handle 13 into three positions which respectively allow admission of compressed air to the ram through pipes 15 to effect lifting, opening of the cylinder to exhaust through a small orifice so allowing the weight of the vehicle to effect lowering, and cut off of the air supply to allow members 25 to remain in any desired position. A ratchet wheel 8 secured to the drum 7 and cooperating with a pawl 9 normally allows free rotation of the drums only when lifting, but, when the handle 13 is raised to effect lowering of the vehicle, the pawl is temporarily pivoted out of engagement with the ratchet. A safety cable 26 is secured to one post 1 at 27 and extends around three sides of the structure to a valve 32 which is normally spring closed to allow air to flow freely to the ram through pipes 15, but; if a projection, e.g. an open door, fouls this cable the valve is opened to apply equal pressures to each side of the piston 4 so locking the hoist until the projection has been removed.

Title: Improvements in the heating of steam-engine cylinders and valve-chests or the casings of steam turbines
IPC: F01K7/02
Filed: 1925-06-29
Abstract: 244,661. Robinson, F. June 29, 1925. Heating parts.-The waste gases from steam boiler furnaces bare circulated through separate jackets e<1>, e<2> on opposite sides of the cylinders f and steam chests f<1> of a steam engine or the casing of a steam turbine, the gases then being discharged through an independent funnel h or being led back through a return pipe to the main funnel. Dampers are arranged so that the waste gases can be discharged directly through the funnel a or directed through a pipe d to the jackets e<1>, e<2>. A fan in the return pipe or the funnel h effects the circulation. In a modification, the jackets e<1>, e<2> are partitioned so that the gases pass through the lower part of each jacket and return through the upper part. The jackets have one wall in contact with the turbine casing, the remaining sides being lagged or they may be open on one side so that the gases are directly in contact with the casing. The funnel a may be divided longitudinally so that only a portion of the waste gases is circulated through the jackets.

Title: Improvements in and relating to coin-detecting mechanism for automatic vending machines
Filed: 1929-05-30
Abstract: 334,239. Wistoft, S. May 30, 1929. Testing edge for milling; coin action, with stationary coin forming abutment. - In a coinfreed vending machine the coin is led to a pocket 9 in which it rests on a fixed knife-edge 15 and an adjustable knife-edge or stop 10 carried by a plate 5 slidable in a guide bracket 2. The plate 5 carries a pin 12 projecting through a slot in the bracket 2 and engaging the upper end of a lever 17, 18. The operating bar 19 of the machine is slidable vertically in a guide 20 on the back plate 1 against the resistance of a spring 39 and is formed with an extension 23 to which is pivoted a latch lever 25 carrying a pin 34 contacting with a cam surface 35 on the lower end of the lever 17, 18. On the drawer, door, or other opening member of the machine being operated the bar 19 is moved upwardly. If a coin having a milled edge has been inserted in the machine movement of the plate 5 to the left is prevented and the lever 17, 18 is held stationary so that the pin 34 rides over the cam surface 35 and the latch lever 25 is moved against the resistance of a spring 31 to escape shoulders 28, 29 on a fixed stop 27. At the end of the upward movement of the bar 19 the nose 26 of the latch lever 25 engages a chamfer 30 on the stop 27 and moves the pin 34 clear of the lever 17, 18 thereby allowing the upper part of the lever 17, 18 to be moved to the right by a spring 36 to release the coin which passes through a slot in the plate to the money receptacle. If the inserted coin has not a. milled edge the upward movement of the bar 19 carries the latch lever 25 into engagement with the shoulder 28 of the stop 27, the pin 34 turning the lever 17, 18 so as to move the plate 5 to the left to cause the stop 10 to push the coin over the knife-edge 15, which is formed with a slot leading to a rejection shoot. If the inserted coin is partially milled the lever 17, 18 is momentarily held and the latch lever 25 partially rotated but the coin subsequently rides over to the knifeedge 15 and the nose of the latch lever engages the shoulder 29 of the stop 27. In a modification the lever 17, 18 is formed at its lower edge with an extension which engages with the extension 23 as the bar 19 approaches the upward limit of its movement so as to rock the lever positively to release the coin and the sliding plate 5 is also formed with a knife-edge engaging the coin so that the coin is gripped over a relatively small arc.

Patent GB-419387-A (GB)
Title: Improvements in or relating to fertilizers
IPC: C05C5/02
Filed: 1933-06-12
Abstract: In the production of fertilizers an aluminium salt, e.g aluminium nitrate and a soluble silicate are caused to react with one another to produce a fertilizing salt and aluminium hydrosilicate or a mixture of aluminium hydrate and colloidal silicic acid in such a form as to be easily decomposable and assimilable by the root fibres. The soluble silicate may be water-glass preferably potash water-glass.  Fertilizing substances, e.g. superphosphate, sodium nitrate, ammonium phosphate or substances containing potassium may be added to the finished product.  The process may be carried out in the presence of ions of phosphoric acid so that aluminium phosphate is formed in addition to the aluminium silicate.  The soluble silicate may be replaced by colloidal silicic acid and the fertilizing salt is provided by the addition of potassium or ammonium phosphate which reacts with the aluminium salt.  These processes may be carried out in the presence of a material having a large surface, e.g. brown coal, peat, clay, kaolin.  To the products of the processes may be added compounds of elements having a stimulating effect on the growth of plants, e.g. germanium, gallium, hafnium, titanium, manganese, in the same or in somewhat greater proportions than those in which they are present in the naturally occurring aluminium silicates.  The Specification as open to inspection under Sect. 91 also states that fertilizers may comprise wholly or partly mixtures of colloidal silicic acid and active aluminium oxide.  This subject-matter does not appear in the Specification as accepted.

IPC: B21K3/04
Filed: 1918-10-16
Abstract: 136,864. Parsons, Sir C. A., Carnegie, A. Q., Bone, M., and Cook, S. S. Oct. 16, 1918. Turbines.-Blades, vanes, and the like are manufactured by extrusion from small billets through shaped apertures in dies, the bases of the blades being formed by the same operation integral with the blade. The die 1 divided into two or more portions is held in a support 2 to register with one or more pegs 3. The die aperture 4 is of the same cross section as the blade base, or such that the blade base can be readily machined from it. The aperture 4 terminates in an orifice 5 shaped like the blade itself. The aperture 4 is tapered to facilitate the introduction of the billet 6 and may be formed with converging sides along the whole of its length. A drop hammer ram 7 or similar tool extrudes part of the billet through the orifice 5 to form the blade 8, stops 9 being provided to limit the motion of the ram. The extrusion pressure may also be applied in a direction other than in line with the orifice. The tool employed is preferably a quick-acting press, but a drop hammer may be used. When blades with fine edges are required the corners of the orifice 5 may be shaped to form a bulb or bead on the fine edge, this bulb or beaded edge being subsequently removed by grinding, machining or drawing.
Patent GB-749955-A (GB)
Title: Degradation of rubber
IPC: C08C19/08
Filed: 1954-06-09
Abstract: An aqueous dispersion of rubber is oxidized (degraded) by treatment with an alkali metal chlorite under non-alkaline conditions.  The oxidation may be carried out under neutral or slightly acid conditions in the presence of an activator, e.g. formaldehyde, or, alternatively, at a pH of from 3 to 4.  The effect of varying the temperature on the bleaching and plasticizing action is discussed. With a stabilized dispersion air or other free oxygen-containing gas may be passed through the dispersion during the oxidation to assist degration.  The degradation may be stopped by adding a bisulphite. The degraded rubber may be chlorinated in its dispersed state or in solution in rubber solvent, e.g. carbon tetrachloride.  In one example 2 gms. of sodium chlorite and 5.5 ccs. of aqueous formaldehyde of 40 per cent concentration were added to 100 gm. of 60 per cent natural rubber latex stabilized oleyl para anisidine sodium sulphonate, giving a mixture with a pH of 6.  The mixture was heated for 17 hours at 60 DEG C. to oxidize the rubber and the product dried to give a rubber of plasticity 20 DEG  Mooney.  In another example the degradation was effected at 20 DEG C. in the presence of air bubbled through the latex.  In a further example hydrochloric acid was added to 100 gms. of stabilized latex, to give a pH of from 3 to 4, and 2 gm. of sodium chlorite added, the whole being then heated for 48 hours at 60 DEG C.  The remaining oxidizing agents was then removed by adding formaldehyde to give a white rubber of Mooney consistency 12.  In a modification of this example, quantities of sodium chlorite less than 0.4 gm. per 100 gm. of latex were used.
