Title: Improvements in or relating to valve assemblages for internal-combustion engines
IPC: F01L3/04
Filed: 1943-11-23
Abstract: 577,427. Valves. WESLAKE, H., BALLARD, W. E., and METALLISATION. Ltd. Nov. 23,1943, Nos: 19563/43 and 5292/44. [Class 7 (vi)] [Also in Group II] Any part of a valve which is liable to erosion or corrosion by burning is alloyed on its surface with a protective metal such as aluminium or silver. After an initial roughening treatment with sand blast &c. the part is coated by a spray gun with the aluminium or an aluminium-cadmium alloy containing not less than 0.3 per cent cadmium, to a depth of not less than 0.006 inch and the part and coating are heated to at least 800‹ C. to alloy them together. The alloy is cooled rapidly and subjected to a known tempering or normalising process. The heat treatment is carried out in an atmosphere which will oxidise the surface of the alloy. The surface is finally abraided slightly and may receive a polishing or burnishing treatment. As shown, the valve head 14 and exposed part 15 of the stem 22 are treated as also are the valve seat 16 and the top 17 of the valve guide. To prevent the guide from rubbing away the alloy on the stem, it is counterbored to provide some clearance at its upper end or the valve stem is reduced in diameter for this purpose. Parts not exposed to the hot gases may be coated without being subjected to the alloying heat treatment. If desired, the seating surface 13 of the valve head may be unprotected to improve its heat conducting properties and the valve seat 16 may be made of an alloy sold under Registered Trade Mark "Stellite" or "Bright Ray." The areas treated are so proportioned to the untreated areas of the valve that the rate of heat dissipation from the latter exceeds the rate of heat absorption the former.

Title: Improvements in electric switch mechanism
IPC: H01H71/50
Filed: 1919-08-14
Abstract: 144,915. Electrical Apparatus Co., and Martin, A. J. Aug. 14, 1919. Switches, quick-action; automatic currentmakers.-Relates to operating-mechanism of the type used in prepayment electricity meters, or in loose-handle current-breakers, where the circuit is closed by the operation of one member and is broken by the operation of an independent member. The switch is normally held open by a spring or the like. During the first part of the closing movement the switch arm turns about one pivot, up to a certain point, whereupon a second fulcrum is introduced about which it pivots to complete the closing movement. The opening of the circuit is effected by eliminating the second pivoting point by independent means, whereupon the switch arm swings back about the original pivot. An actuating-pin 12 mounted, for example, on a coin-freed handle engages with the end 11 of a lever 3 carrying the switch 2. This lever is pivoted at 14 on a second lever 1 pivoted at 15, both levers being normally held against a stop 7 in the position shown in Fig. 1, by a spring 5. The pin 12 first swings both levers about the pivot 15 until a pin 8 on the lever 3 drops into a recess 9 on a spring-controlled catch lever 10. The pin 12 then passes away from engagement with the part 11, whereupon the lever 3 is swung by the spring 5 around the new pivot point 8 to close the switch, Fig. 2, and the part 11 remains out of reach of the pin 12. The circuit is opened when the catch-lever 10 is depressed, as shown by the arrow Fig. 1. This leaves the arm 3 free to swing back about the point 14 into line with the arm 1, after which both arms are turned about the pivot 15 into their initial position. The catch lever may be released in any suitable manner, such as by an electromagnet or cam controlled by the meter. A modified arrangement of the catch-lever and release means is also described.

Title: Improvements in or relating to a method of separating contaminating material from a liquid
IPC: B01D17/02
Filed: 1948-08-04
Abstract: 662,646. Purifying water. INFILCO, Inc. Aug. 4, 1948 [Sept. 13, 1947], No. 20584/48. Class 46 Adsorbable impurity such as oil, e.g. vegetable oils, saturated or unsaturated oils, is separated from polluted water by establishing a suspension of material philic to the impurity in a body of water undergoing treatment, maintaining in said suspension a circulation through a closed cycle path, passing impure water and fresh philic material into the circulating suspension, separating treated water from the circulating suspension and withdrawing it from the process and withdrawing philic material with adsorbed impurities from the process. In carrying out the invention, as shown in the flow diagram of known apparatus the body of water undergoing treatment is functionally divided into a lower mixing zone containing the suspension of oil-philic material and a superposed quiescent treated-water zone, the entering oily waste water being introduced, preferably continuously, into the suspension, e.g. in the mixing and reaction zone and additional oil-philic material being introduced, preferably continuously into the suspension, e.g. into the reacting zone which is continuously agitated. Clarified water is withdrawn from the upper surface of the suspension into the treated water zone. Oil-contaminated philic material is withdrawn from a concentrator equal in amount to the philic material added. The philic material may be sludge from a water softening plant, and the oil-contaminated sludge (calcium carbonate and carbon) withdrawn from the process may be of sufficiently high oil content that on drying it is burnable, e.g. in a furnace, or carbonized to form a source of oil-philic material which is fed back to the suspension in the treatment zone. This oil-philic material is retained in the suspension until the content of oil absorbed thereby is at least 50 per cent of the weight of the dry solids. The particles of oil-philic material should be of a size of the order of calcium carbonate particles formed in water softening. The suspension contains from 20 to 25 per cent solids by volume. Other oil-philic materials referred to are lime and iron, calcium carbonate and hydroxide, aluminium chloride and lime. Phenol may be removed by employing carbonated sludge or activated carbon as the philic material.
