Abstract: 463,744. Closing bags. SOUTHALL & SMITH, Ltd., WEAVER, F. W., and GWILT, C. Nov. 22, 1935, No. 32387. [Class 94 (i)] In order to flatten bags filled with tea and the like to enable them to be satisfactorily sealed by bending over a gummed flap, the bags d are passed between driven rollers a arranged beneath the weighing and filling mechanism and spaced so as to flatten and spread the contents. To prevent the flaps from being dragged sideways by the rollers, they are engaged by an adjustable guard strip e, and the bag falls into a funnel formed by curved plates b, in which they are supported by a conveyer band c. 'The band c carries the bags into the grip of conveyer bands h and i arranged vertically to engage the sides. Meanwhile, the upper parts of the bags are engaged by plates f forming a converging path, and corrugated at the contacting edges to smooth the sides of the packets. Subsequently, the flaps are gummed by a roller j taking its supply from the side of a vertically mounted roller rotating in a reservoir. Rollers n, o having coacting bevelled peripheries, bend the flaps in the direction in which they are to be folded to such an extent that they can be engaged and turned down on to the side of the packet by a curved plate p. Conveyer bands q press the flaps against the packets, which now pass to the delivery end of the machine.

Abstract: 856,437. Generating combustion products under pressure. ARMSTRONG SIDDELEY MOTORS Ltd. Sept. 23, 1958 [Oct. 19, 1957], No. 32718/57. Class 51 (1). In a combustion system for a gas turbine engine, an annular manifold is provided having an open upstream end to receive a proportion of the output from an air compressor of the engine and a main supply of fuel, this air and fuel being for main combustion. Either the inner wall or the outer wall of the manifold forms an upstream wall portion of the flame tube and is provided with ports through which the mixture of main combustion air and fuel enters the flame tube. Means are also provided for delivering a pilot supply of fuel and air from the compressor in an upstream direction to the closed upstream end of the flame tube so as to provide a pilot combustion flame into which the 'main combustion air and fuel are discharged. In the annular type of combustion apparatus shown, the annular flame tube comprises an outer wall 12, 20 and an inner wall 13, the two walls being closed at the upstream end. The flame tube is mounted within an annular air space formed by outer and inner walls 11, 15. The upstream portion 12 of the outer wall of the flame tube is surrounded by a wall 17 so as to form an annular manifold space open at its upstream end and closed at its downstream end where the walls 12, 17 are secured together. An annular sealing ring 19 is disposed at the downstream end of the space. The inner wall 12 of the manifold is formed with three rows of openings 28, 29, 30 through which air from the engine compressor and main fuel from the ring manifold 26 discharge from the manifold 12, 17 into the flame tube. The wall 17 is formed with openings 22 from which V-shaped pipes 21 extend into the flame tube, the discharge ends 21a of the pipes being directed towards the closed upstream end of the flame tube. Fairing members 23 are disposed between the walls 11, 17 being open at their upstream ends for inflow of air from the compressor. The fairings each surround an inlet to a V-shaped pipe 21, and pilot fuel is supplied to each pipe 21 through a pipe 27 so that pilot fuel and air discharge from the pipe outlets 21a and produce pilot combustion which causes ignition of the main fuel and air mixture supplied through openings 28, 29, 30. Further air enters the flame tube through openings 25 in the outer wall 20. Air supplied to the space between the inner wall 13 of the flame tube and the casing wall 15 enters the flame tube through spaces formed between overlapping sections of the wall, thereby cooling the inner surface thereof.

Title: Stabilized vinyl chloride resin compositions
Inventor: WEINBERG ELLIOTT LAWRENCE
IPC: C07F9/90
Filed: 1953-11-26
Abstract: Vinyl chloride resin compositions are stabilized by the addition of an antimony SS1S11-tri-(mercaptoacid ester) of the formula Sb(SRCOOR1)3, wherein R is an alkylene, arylene or aralkylene radical, or an alkylene radical substituted by a free or esterified carboxyl group, and R1 is an alkyl, aryl or aralkyl radical or an alkyl radical substituted by a free or etherified hydroxy group or by an esterified carboxyl group (see Group IV (b)).  The resin composition may contain up to 10 per cent, but preferably about 2 per cent, by weight of the stabilizing ester.  The composition may also contain a plasticizer such as a phosphate plasticizer. The compositions and products derived therefrom such as plastic film, show improved resistance to light and heat deterioration. The stabilizing esters described are antimony SS1S11 - tri - (nonylmercaptoacetate), -(octadecylthiomalate),-(decylmercaptoacetate), -(glyceryl monoricinoleate monomercaptoacetate) and -(dihydroabietyl mercaptoacetate).  In example (5) the stabilizing effect of the esters on vinyl chloride resin in the form of plastic film is shown.ALSO:Antimony SS1S11 tri-(mercaptoacid ester) compounds of formula Sb(S.R.COOR1)3 wherein R is an alkylene, arylene or aralkylene radical, or an alkylene radical substituted by a free or esterified carboxyl group, and R1 is an alkyl, aryl or aralkyl radical, or an alkyl radical substituted by a free or etherified hydroxy group or by an esterified carboxyl group, have a stabilizing effect on vinyl chloride resin compositions (see Group IV (a)).  The compounds are prepared by condensing antimony trioxide with a mercaptoacid ester.  The presence of an inert organic solvent such as toluene, benzene or methyl alcohol facilitates the reaction.  The water produced during the reaction may be stripped by heating or refluxing.  R may be derived from mercaptoacetic, mercaptophenylacetic, b -mercaptopropionic, thiomalic or thiosalicylic acids and R1 may be derived from decanols, glycerol, glycol monoesters, dihydroabietyl alcohol, p-cresol or phenoxyethanol. In examples, antimony trioxide was reacted with nonyl mercaptoacetate, octadecyl thiomalate, decyl mercaptoacetate, glycerol monoricinoleate monomercaptoacetate and dihydroabietyl mercaptoacetate.  Specification 282,427, [Class 2 (iii)], is referred to.
