Abstract: 567,066. Chimneys and fireplaces. SNELLING, J. C., and RICHARDSON, R. A. Feb. 4, 1943, No. 1868. [Class 25] [Also in Group XI] A complete chimney stack, with which is incorporated one or more fireplaces 21, each having its own flue, is built up as an independent unit of internal flue tubes 32 and external blocks 39, 43, the spaces between the latter and the tubes 32 and fireplaces 21 being filled in with concrete 41. Iron tie-members 42 are provided for connecting the independent stack into the main structure of the building. The flue tubes 32 are formed with collars 34 at one end for jointing purposes and where it is necessary to divert the direction of the flue, there are employed bend pieces 36 which are so shaped that the flue makes an angle with the horizontal of not less than 60 degrees. The blocks 39, 43 are formed with inwardly-projecting parts 45 which are rounded at 44, 46 and form a bond with the filling concrete 41. Fig. 1 shows the invention applied to a stack incorporating two back-to-back fireplaces 21, the firebacks 22 being of weir formation as shown and being surmounted by lintel blocks 28 which bear at each side on the outer blocks 39 and are shaped at their lower and upper ends to conform respectively to the firebacks 22 and the first sections 29 of the flue linings. The fireplace bottoms 21 have projections 23 to engage with recesses in hearth blocks 24 which are each formed with a raised rim 25 constituting a curb. The blocks 39 immediately around the fireplaces may be tiled on their outer surfaces and form a complete surround without further addition. Figs. 5, 6 show the construction of that part of the stack projecting above the roof, this part being built up of blocks 50 having projecting and recessed portions 51, 52 which form joints resistant to rain penetration and provide, when the blocks are reversed in adjacent courses, a bonding on the outside. The top two courses are formed with tapering flues which, when the courses are reversed for bond, provide a venturi formation at the stack outlet. This outlet is covered by a slab 56 supported on blocks 54 having side openings 55.

Title: Process for the manufacture of yarns
Filed: 1929-01-21
Abstract: 304,606. FiÚvet, C. LiÚnard-. Jan. 21, 1928, [Convention date]. Yarns; processes; fibres, batching.-The wool like fibres obtained by the process described in Specification 304,602 are used in the production of a yarn adapted to be spun unbleached or dyed and suitable for the manufacture of fabrics or cloth for ready-made clothes, for the weaving of fulled or napped or brushed products, and for making velvet carpets, " Indian wool," hosiery and the like. For this purpose the fibres are mixed with wool or other fibres, the process comprising opening in a Garnet machine, mixing and carding, the latter being done in two stages after which spinning of the yarn may be done by looms. Before mixing, the materials are treated with a lubricant such as oleine, olive oil, castor oil, or colza oil, but sulphonated castor oil is preferred, which latter when neutralized and dissolved in petroleum spirit prevents oxidation of the cards used in the carding operations.

Title: Improvements in and relating to spool valve governors
Inventor: WASHBOURN JACK
IPC: F16K11/065
Filed: 1961-01-18
Abstract: 923,745. Valves. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Dec. 7, 1961 [Jan. 18, 1961], No. 2024/61. Class 135. A spool valve governor comprises a hollow body member 10 having a fluid pressure inlet connection 11, an outlet connection 12 and an atmosphere connection 25, a piston with sealing means 19, 20 movable from a position in which the outlet is connected to the atmosphere to one in which it is connected to the inlet, and resilient means biasing the piston towards the first-mentioned position. The inlet 11 may be connected to a reservoir supplied by a compressor until a predetermined pressure is reached when the piston moves upwardly causing the seal 19 to pass over a circumferential series of ports 14 and so isolate the outlet 12 from the atmosphere connection 25. Further upward movement of the piston causes the seal 20 to pass over a second similar series of ports 15 so that the main reservoir pressure becomes effective through the connection 12 to open a large valve in the compressor delivery or to hold the suction valves off their seats. Reservoir pressure also passes through the ports 14 to accelerate the movement of the piston by acting on a stepped portion of the latter. This stepped portion also ensures that the valve closes at a lower pressure than that at which it opens.

Title: Improvements relating to the saccharification of wood and other cellulosic materials
IPC: C13K1/02
Filed: 1929-01-22
Abstract: 311,695. Distilleries des Deux-SÞvres. May 14, 1928, [Convention date]. Glucose.-Completely dried cellulosic material, either pure or mixed with other products, is treated with anhydrous or highly concentrated 'formic acid in the presence of a small quantity of catalyst acids or salts such as sulphuric, hydrochloric, phosphoric, sulphurous, benzenesulphonic or toluenesulphonic acid, or chloride of zinc, calcium or iron or bisulphates, and the formates obtained are hydrolyzed directly in a sufficiently concentrated formic medium, by the progressive addition of a small quantity of water whilst assisting the reaction by stirring and heating. The hydrolysis is completed by boiling the sugars and dextrins in aqueous solution in the presence of a mineral acid, with or without pressure. The cellulose if in the form of wood may be given a preliminary treatment with dilute solutions of mineral acids to convert it more or less thoroughly to hydro-cellulose and convert pentosans into pentoses which may be eliminated and converted into furfurol. Examples are given of the treatment of paper pulp and sawdust. The formic acid is recovered by distillation in the presence of a liquid forming therewith an azeotropic mixture, or by distillation in the presence of an alcohol giving with the formic acid a volatile formate, which is subsequently saponified, or by bringing the formic acid into aqueous solution with the sugars, and extracting it by methodical exhaustion in counter current by means of solvents insoluble or but. slightly soluble in water.

Patent GB-571496-A (GB)
Title: Improvements in and relating to resinous compositions
IPC: C08F18/08
Filed: 1942-02-25
Abstract: Syrupy synthetic resinous compositions are made by heating together diallyl phthalate containing a minor proportion, e.g. 1-5 per cent by weight of benzoyl peroxide and a small amount, e.g. 5-10 per cent by weight of copper, removing undissolved copper, adding a further small quantity, e.g. 1-2 per cent by weight of benzoyl peroxide, and subjecting to a further heat treatment.  Solid compositions may be obtained by removing dissolved as well as undissolved copper before the further addition of benzoyl peroxide or by adding a larger quantity of benzoyl peroxide-6 per cent by weight for the further treatment. In example 1, monomeric diallyl phthalate containing 1 per cent of benzoyl peroxide and 5-10 per cent of copper turnings is heated to 100 DEG  C. for 15 minutes, filtered from the copper turnings, and after addition of a further 1 per cent of benzoyl peroxide again heated to 100 DEG  C. for 10-20 minutes.  The viscosity of the mixture increases rapidly, but a gel is not formed. In example 2, diallyl phthalate containing 5 per cent of benzoyl peroxide is heated with 5-10 per cent of copper turnings at 100 DEG C. for 15 minutes, decanted from the copper, diluted with diallyl phthalate and heated quickly to 170 DEG  C., this temperature being maintained for 10-15 minutes to destroy excess benzoyl peroxide.  The resulting liquid may be stored for any length of time.  Heated to 80-120 DEG  C. with 2 per cent benzoyl peroxide for 30 minutes it polymerizes to a consistency approximately that of honey.  Addition of more benzoyl peroxide up to 6 per cent and further heating for 14 hours at 80 DEG  C. yields a rubbery gelled mass.  Thin films of thread materials may be hardened by baking at 150 DEG  C. for about 12 hours.  If dissolved copper is removed from the liquid resulting from the first heating, by addition of zinc followed by filtration or centrifuging the product may be gelled by heating for 15 minutes at 80 DEG  C. with 2 per cent of benzoyl peroxide.  Curing the gelled product for 7 hours at 80 DEG  C. yields a fairly tough rubbery material which may be further toughened by 13 hours additional cure at 100 DEG  C.  The syrupy reaction products form putty-like mixtures with a filler, e.g. asbestos film or china clay, and benzoyl peroxide and these mixtures may be cold-moulded and hardened by heat. Addition of excess methyl alcohol to the syrupy reaction product precipitates a fusible polymer soluble in acetone or benzene.  This precipitate mixed with monomeric diallyl phthalate and benzoyl peroxide forms a putty-like mass which may be hot or cold-moulded. The syrupy products may replace monomeric diallyl phthalate, e.g. in the manufacture of solventless varnishes comprising interpolymers of unsaturated alkyd resins and diallyl phthalate as described in Specification 15144/40 (as open to inspection under Sect. 91 of the Acts).
