Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/30
Filed: 1927-05-14
Abstract: 277,618. Westinghouse Brake & Saxby Signal Co., Ltd., (Assignees of Compagnie des Freins Westinghouse). Sept. 20, 1926, [Convention date]. Fluid-pressure. - Fluidpressure braking-apparatus is provided with a chamber adapted to receive fluid under pressure from the train pipe when the brakes are applied, this chamber being in restricted communication with another chamber to stabilize the train pipe pressure and to prevent movement of the triple valves to roelease position by surging in the train pipe. Reduction of pressure in the train pipe connection 13 causes movement of the triple valve piston 3 to vent the train pipe to a chamber 9 by passages 15, 16 and cavity 17 in the slide valve 5. The fluid under pressure thus vented to the chamber 9 slowly escapes by a restricted passage 12 to a chamber 8. This vented fluid may return to the train pipe to make up any fall in pressure below a predetermined value. When the brakes are released these chambers are vented by the slide valve through an exhaust port 18. The chamber 8 may be connected directly by a passage containing a check valve to the passage 16 in order to hasten the exhaust of fluid from this chamber. Flow of fluid from the chamber 9 to the chamber 8 may be prevented till a certain pressure has been attained in the chamber 9, by means of a spring-controlled check valve arranged before the restricted passage 12. In this modification of the invention the chamber 8 is exhausted by means of a separate passage leading to the slide valve face.

IPC: G01C3/20
Abstract: 131,611. Barr & Stroud, Barr, A., and Stroud, W. Jan. 22, 1917. Drawings to Specification. Range-finders .-Range-finders (such as described in Specification 125,587) for measuring heights directly and in which the compensation for varying angles of sight of the target is obtained by rotation of the translated refracting prisms, are provided with prisms which are fixed in their own plane but are rotated with the translated prism and are so arranged that rotation produces no shift of the image when the translated prism is in the infinity position. The limitation of range of the instrument due to the refracting prism movements being restricted by the presence of the eye-piece prisms is thus removed. There may be a separate prism for each telescope system, or a combined prism may be used for the two systems.

Abstract: 930,892. Supplying liquid fuel to burners. DOWTY FUEL SYSTEMS Ltd. April 19, 1960 [April 20, 1959], No. 13423/59. Class 75 (1). [Also in Group XXVI] A fuel supply system for a spill nozzle 6 of a gas turbine engine comprises a fuel entry passage including a heat-exchanger 28 and a flowmeter 36, and a spill passage extending through the heat-exchanger 28 in heat-exchange relation with the entry passage and connected to the entry passage downstream of the flowmeter 36. The spill fuel heats the entry fuel before the latter passes through the flowmeter 36. The spill fuel is divided into two parts, one part passing along a pipe 25 to the heat-exchanger 28 and the other part passing along a pipe 26 and through a valve 42 to by-pass the heat-exchanger. The valve 42 operates to maintain constant the temperature of the entry fuel leaving the heat-exchanger and comprises a metal bellows 44 connected by a pipe 46 to a temperature sensing bulb 47 located in the entry fuel. The flow of spill fuel is controlled by a valve 14 actuated by a servo piston 17 disposed in a cylinder 18 and responsive to the pressure difference across a restriction 21 in a fuel flow vent path controlled by a control unit having a valve-actuated by signals received from an engine speed governor, an air fuel ratio control and a minimum fuel flow control. The heatexchanger includes a passage through which passes lubricating oil from the engine. A second embodiment, Fig. 2 (not shown), includes a main pump supplying fuel to a circulating system comprising a circulating pump connected to the entry and spill passages of a spill nozzle. The main pump may be connected to either the entry or the spill passages. A flowmeter is disposed upstream of the main pump and a heat-exchanger is disposed upstream of the flowmeter. Part of the spill oil passes through the heat-exchanger and returns to the circulating system. The main pump may be of fixed displacement with its delivery controlled by a by-pass valve, or it may be a variable displacement pump or it may be a centrifugal pump controlled by throttling of the delivery passage.

Title: The manufacture of melamine-aldehyde resins
IPC: C08G12/42
Filed: 1943-08-20
Abstract: Alkylated melamine-aldehyde resins suitable for lacquers, in textile treating and finishing processes, for treating paper or leather, or as adhesives or binding agents, are prepared by distilling a mixture or condensation product of melamine and aldehyde in which there is less than 3.5 mols. of aldehyde per mol. of melamine with a mixture of methanol and butanol or propanol.  Dry butanol or propanol may be fed in during distillation at a rate consistent with that at which the distillate is collected.  In the example, 3 mols. of formaldehyde as 37 per cent formalin were warmed with 1 mol. of melamine to yield a clear solution.  A mixture of equal parts of butanol and methanol was added and the solution distilled at atmospheric pressure, further butanol being added at the same rate as the distillate is collected. When sufficient distillate had been collected, the residue was vacuum concentrated and a clear water-white solution obtained as product. Too much methanol should not be added as, although the resin yield is not affected, the tolerance of the lacquers for hydrocarbons and the hardness of films from the lacquers are reduced.  Pigments, dyes, lakes, fillers may be mixed with the products.  Suitable adjuvants are Sudan IV, toluidine red, ochre, red oxide, zinc oxide, titanium dioxide, nigrosine, wood flour, wood fibre, paper dust, clay, zinc, glass wool, mica, granite dust, silk flock, cotton flock, carborundum, paper, cloth or sand.  Natural or synthetic resins such as shellac, cellulose esters or ethers, urea resins, phenolic resins, alkyd resins, fatty oil-modified alkyd resins or ester gums may also be added.  Specification 552,555 is referred to.
