Abstract: 315,216. F÷ppl, O. July 9, 1928, [Convention date.] Physical or molecular structure, altering by mechanical treatment.-The surface of a machine part or other structural member subject to alternating or changing stress is compressed as by hammering with a bail-headed hammer, the whole surface being covered by repeated blows. The part may be drawn under a ball subjected to pressure, to produce lines of pressure which are arranged beside each other to cover the entire surface. A rotary member may be mounted in a lathe and acted on by a ball pointed tool mounted in the tool-holder. Specification 164,749 is referred to.

Title: Improvements in and relating to the manufacture of electric lamps
IPC: H01K1/30
Filed: 1938-06-16
Abstract: 516,004. Making small electric lamp bulbs. EVER READY CO. (GREAT BRITAIN), Ltd., and BEESTON, E. F. June 16, 1938, No. 17946. [Class 56] A method of making bulbs for electric lamps, particularly those of small size, consists in applying a controlled and regulated flame to'and around the end of a glass tube disposed horizontally or substantially horizontally, the heat being applied until the glass has fused into a solid mass 4, Fig. 2, having the shape of a lens with an outer convex surface. Air pressure or suction may be applied to the open end of the tube to assist in shaping the glass, particularly when a double convex lens is required. After the lens has been formed, the tube may be heated just below the lens and the softened glass blown out in a mould 9, Fig. 5, to form a hollow shell 11 which is disposed immediately at, and curves directly into, the base of the lens. Specification 440,542 is referred to.

Title: Improvements in and relating to derivatives of purine and the manufacture thereof
IPC: C07D473/24
Filed: 1955-06-22
Abstract: The invention comprises compounds of the formula <FORM:0836696/IV (b)/1> in which X is hydrogen or an amino group and R is an alkyl radical of three to eight carbon atoms or an aralkyl radical of 7 or 8 carbon atoms the aryl nucleus of which may be substituted with one or more halogen atoms, hydroxy groups, nitro groups or alkyl groups having up to 4 carbon atoms.  They may be prepared by reacting the appropriate mercaptopurine with the halide of the desired substituent radical in the presence of an acid acceptor. Examples describe the preparation of compounds of the above formula wherein X is hydrogen and R is n-butyl, benzyl, o-, m- and p-chlorobenzyl, m-nitrobenzyl, m-hydroxybenzyl and o- and p-methylbenzyl and of compounds wherein X is amino and R is n-propyl, n-butyl, benzyl, 3 : 4-dichlorobenzyl, o- and p-chlorobenzyl and o-, m-and p-methylbenzyl.  In the Provisional Specification no limitation is placed on the number of carbon atoms in the radical R and the aryl moiety of this radical may contain any substituents.

Title: Fuel injection systems for gas turbine engines
IPC: F02C9/26
Filed: 1972-04-19
Abstract: 1390368 Gas turbine engine fuel systems ROBERT BOSCH GmbH 19 April 1972 [24 April 1971] 18064/72 Addition to 1327017  Heading F1G [Also in Division F2] In a fuel system for a vehicle gas turbine engine claimed in the parent Specification, 1327017 the valve provided in the fuel line for maintaining a substantially constant pressure drop across the fuel metering valve is modified to afford one or more flow openings in the fixed valve seat which have a total perimeter which is substantially the same as the perimeter of a normal single substantially circular flow opening, the total pressure crosssectional area of the flow opening or openings being substantially smaller than the pressure crosssectional area of the normal opening in order to reduce the effect of the fuel back pressure on the diaphragm which co-operates with the valve seat. Thus the valve seat 39 may have three or four small circular bores 44 (or two small rectangular bores) instead of a single large circular bore, whereby the total cross-sectional area of the bores is substantially smaller than the cross-sectional area of the single bore, while the total perimeter remains the same. This reduces to a minimum the disturbing effect on the constancy of the pressure drop exerted by the fuel back pressure acting through the bores 44 on the diaphragm 37.

Abstract: 348,927. Automatic temperature alarms. UNTERHOLZNER, J., 62, Herzogstrasse, Munich, Germany. June 18, 1930, No. 18616. [Class 47 (i).] An automatic temperature alarm, particularly for use in liquids, comprises an airtight float a which is formed at its lower end as a sealed box b with a corrugated diaphragm d and containing a liquid e. The cover carries a toothed rod f in mesh with a lantern wheel h loose on a shaft g. A clutch member i fixed to the wheel h cooperates with a clutch member k fast on the shaft g and fixed to a ratchet wheel y. A spring l holds the clutch members together, and a spiral spring o has one end fixed to the shaft g. The wheel y is connected by a spring pawl to a gear wheel p which cooperates with gears q, r to drive a hammer t against the resonant top u of the float. When the liquid e is heated and evaporates, the rod f rotates the shaft g and winds up the spring o, until an abutment n on the rod engages a flange m on the wheel h, to separate the clutch members i, k. The spring o then unwinds and drives the hammer t. A wire net x limits movement of the cover d. In a modification, the spring o is omitted, the cover d driving the shaft g with a snap action. In another modification, the cover d acts directly, with a snap action, on the hammer. The concentric corrugations of the cover d may be transversely corrugated, to increase its elasticity.
