Filed: 1947-06-16
Abstract: 624,494. Axial-flow compressors. BRISTOL AEROPLANE CO., Ltd., MARCHANT, F. C. I., and ROBINSON, S. June 16, 1947, No. 15809. [Class 110(i)] Balancing end-thrust; multi-stage compressors.-The compressed fluid is applied to a face of the rotor to produce an axial thrust opposing the end thrust; in a multistage compressor plant the applied fluid is derived from another of the compressors. In the arrangement shown, a low-pressure turbine-type compressor 6 on a shaft 8 feeds a similar high-presure compressor 7, driven by a tubular shaft 9, through an annular duct 10 of which the walls are connected by radial arms and which carries diaphragms 14, 15. The diaphragm 14 carries a bearing for the shaft 8 and encloses with the low-pressure rotor a space which communicates with the duct 10 only through a labyrinth packing. The diaphragm 15 ends in a labyrinth packing surrounding a bearing 17 by which the high-pressure rotor is supported, and forms with the end of this rotor a chamber 27 which communicates with the duct 10 through a narrow gap; a similar chamber 39 at the other end of the rotor communicates with the outlet duct of the compressor only through a labyrinth packing, and a lower pressure is maintained in this chamber than that in the chamber 27, for example, by connection to an intermediate stage of the compressor 6, so that there is a resultant thrust to the right. This thrust may be given the required value by selecting the diameter of the inner wall 25 of the chamber 27, which is integral with a plate fixed to the end of the rotor, to determine the effective diameter of this plate.

Abstract: 875,848. Valve bags. METAL BOX CO. Ltd. March 24, 1960 [May 12, 1959], No. 16319/59. Class 94(2). A bag is made from heat-sealable material, preferably polyethylene, by heat-sealing the end of a flattened seamless tube at 10 to form the bottom, the mouth being heat-sealed at 11 about and to a valve which comprises two polyethylene strips the facing surfaces 9 which are not sealed together, by the heat, along the line 11 and which thus provide an opening into the bag for, e.g. a drinking straw 12, the strips having previously been joined along their edges 2 to form a valve tube. One side of each polyethylene strip is first subjected to an oxidising flame to render the surface 1 inert to heat sealing and thus the edges 2, Fig. 2, cannot be joined by the application of bar heaters so they are joined by heat sealing, using a heated wire or knife-edge. Alternatively, margins of the strips may be left free from the flame treatment to enable bar-heaters to be used. An additive is included in the polyethylene strip, during or after its extrusion, to reduce natural adherence between overlying surfaces of the material. The end of the valve tube may be as in Fig. 6, in which the tube is opened so that the part 6 is drawn into the tube to extend through the end 7 and a portion 8 of the opposite end is turned in and so provides a lead for the insertion of a drinking straw or filling nozzle.

Abstract: A heat-curable composition is prepared by reacting a 3, 4-epoxycyclohexylmethyl-3, 4-epoxycyclohexanecarboxylate or an alkyl substituted derivative thereof (see Specification 768,157) with 0,1-1,5 mols of polycarboxylic acid and/or ester thereof containing free COOH groups, per mol of diepoxide.  When the amount of polycarboxylic acid and/or ester falls within the range 0,1-1,0 mols, it may be supplemented with up to 0,1 mols of polycarboxylic acid anhydride, and when the amount is between 1,0 and 1,5 mols it may be supplemented with up to 1,0 mol of anhydride.  Lists of suitable polycarboxylic acid compounds are given in the Specification.  They include COOH-terminated polyesters.  Suitable anhydrides are also listed.  The ingredients are heated together, e.g. at 25-250 DEG C. until gelation occurs or may be cured in a mould.  If gelation occurs before a homogeneous mass is formed the acid compound may be dissolved in a solvent to lower its rate of reaction.  Five examples are given of preparation of suitable epoxides, and many more examples are then given of reaction of the epoxides with various polycarboxylic acid compounds.  In several cases the physical properties of the cured mixtures are given.  Most of the examples use 3, 4-epoxy-6-methyl cyclohexylmethyl-3, 4-epoxy-6-methyl cyclohexanecarboxylate.  In the last example this compound was mixed with an acid ester prepared from three mols of succinic anhydride and two mols of glycerol and the mixture heated to 130 DEG C. for 5 minutes and reaction stopped by rapid cooling.  The solid product was dissolved in methyl isobutyl ketone and applied as a thin film to a glass surface, dried for 1 hour at 50 DEG C. and the film cured at 160 DEG C.  Specification 852,409 also is referred to.  Reference has been directed by the Comptroller to Specification 768,157.
