Title: Improvements in or relating to the manufacture of dextrins, sugars and other products from cellulosic materials
IPC: C13K1/02
Filed: 1931-03-07
Abstract: Cellulose or cellulosic materials are transformed to conversion products by treatment with relatively non-volatile acids such as sulphuric acid in the presence of acetone.  The products are further converted to dextrins &c. by treatment with dilute acid.  The cellulose may be first impregnated with a large quantity of a dilute solution in acetone of the acid, the excess being then expressed and the acid is concentrated by evaporation of part of the acetone.  The acid is recovered from the conversion products by extraction with acetone or ether or other organic solvent and used again.  A small amount of water may be present and the cellulose may be impregnated with the water before adding the acid.  The Provisional Specification describes the use of other organic solvents such as ether instead of acetone. Specification 376,372, [Group VI], is referred to.ALSO:Cellulose or cellulosic materials are transformed to conversion products by treatment with relatively non-volatile acids such as sulphuric acid in the presence of acetone.

Title: Improvements in and relating to apparatus for positioning fish
IPC: A22C25/12
Filed: 1945-03-21
Abstract: 601,907. Fish-filleting machines. ATLANTIC COAST FISHERIES CO. March 21, 1945, No. 7162. Convention date, June 17, 1944. [Class 28(ii)] A fish to be fed to pairs of rotary filleting discs which shave off fillets from the sides, is accurately positioned belly up between two spring pressed side engaging plates forming a final gate G from which the fish is pulled by a pair of grippers. The fish, tail leading and back down and passing from right to left in Fig. 1 is placed in a feed conveyer F, Fig. 1, the feed plates 46, Figs. 3 and 5, of which feed it to a gate G, Figs. 1 and 2. A preliminary gate is described in Specification 589,841. A different final positioning gate is disclosed in U.S.A. Specification 2,149,021. The fish tail passes into and through a guide 52, Fig. 3, close to the lower ends of the plate 46, Fig. 3. As the tail passes through the gate G, it engages the wings 326, Fig. 6, of hinged plates 300 which form the gate G, thereby being positioned vertically by the wings 326. Pads 340-344 (merging with the plates 300) engage the sides of the fish which becomes wedged between them so preventing temporarily further movement of the fish although the feed conveyer F continues to travel beyond the mouth of the gate G. The pads 340 taper down and forward to urge the fish downwardly. At this stage grippers 72, Fig. 2, operated by fixed horseshoe-shaped cams 90 and rollers 73 begin to grip the tail and a bevel 94, Fig. 3, of block 70 on the conveyer chains, engages roller 254 to release a primary female latch 210 and a secondary latch 280. Since the feed conveyer F travels at a higher speed than the conveyer carrying the tail grippers 72 a number of short plates 46 are provided to allow a space for the grippers 72 to close on the fish until the conveyer no longer overlaps. Release of the latches 210 and 280 allows the tail, clamped by grippers 72 to be pulled forwardly from the gate. The gate sides 100 are pivoted on shafts 104 and are geared together so that they are forced apart in unison against spring pressure by the thick portion of the fish passing therethrough, the fish being kept in this position thereby and drawn through the filleting knives. If foreign matter holds the gate members 100 open, the grippers 72 follow the contour 136 at the bottom of each gate 100 and engage the hinged plates 300 and press them toward each other and away from the gate members 100 so avoiding damage to the grippers 72. Specifications 452,688, 466,674, 597,943 and U.S.A. Specification 2,406,907 also are referred to.
Patent GB-559053-A (GB)
Title: Alkylation process
IPC: C07C9/16
Filed: 1942-05-27
Abstract: 559,053. Alkylation process. SHELL DEVELOPMENT CO. May 27, 1942, No. 7180. Convention date, Oct. 11, 1941. [Class 2 (iii)] Alkylatable organic compounds such as isoparaffins, cyclopentanes, cyclohexanes, aromatic hydrocarbons, phenols, cresols, aniline, nitrobenzene, and halobenzenes, are alkylated with a normally liquid olefine capable of forming an active oxygen-containing compound which tends to shorten the life of the alkylation catalyst, the alkylation taking place in the substantial absence of said active oxygencontaining compound. Its absence may be obtained by adding an antioxidant such as a naphthol, tertiary butyl phenol or cresol, or resorcinol, to the olefine, or distilling the olefine to obtain a fraction having a lower concentration of said oxygen-containing compound, or by treating the olefine with reducing agents such as sodium bisulphite or by using an oxalic acid-sulphuric acid mixture. The olefine used is preferably a polymer of a lower boiling olefine, such as ethylene, propylene, butylenes, isobutylene, amylenes, cyclopentene, cyclohexene, and methyl cyclohexene, or the polymers may be made from the corresponding alcohols. Interpolymers of isobutylene and secondary butylenes may be used. The catalyst may be sulphuric, chlorosulphonic, fluorosulphonic, hydrofluoric or hydrofluoroboric acid, or Friedel-Crafts type catalysts such as aluminium chloride, aluminium chloridekerosene, aluminium chloride-sodium chloride or aluminium chloride with antimony trichloride. Specifications 479,657, 514,043, 527,720 and 553,749 are referred to.

Title: Improvements in or relating to conveyors
Inventor: BAKER JAMES MUNDY
IPC: B65G19/16
Filed: 1951-03-30
Abstract: 700,924. En-masse conveyers. REDLER CONVEYORS, Ltd. March 27, 1952 [March 30, 1951], No. 7461/51. Class 78 (1). An endless tension member having laterally extending flights is arranged in a conveying casing and passes around a reversing member before entering the casing, and an inlet for granular material is arranged at a point in advance of the reversing member, the arrangement being such that material from the inlet is guided around the reversing member such that on entering the conveying casing it enters a clear space between the bottom of the conveyer flights and the bottom of the casing where it is sandwiched and caused to move along the casing by the movement of the flights. As shown, fibrous material passes from a supply hopper 40 on to the upper run of an endless tension member 18 which conveys the material in normal manner along a plate 29 within a casing 10 until it reaches a drum 19 at the end of this run. The material is then guided around drum 19 by a plate 38 bent into a semi-circle so that the material is now beneath the tension member in the space 45 between the tension member and the smooth bottom 11 of a trough containing the lower run of the tension member. The material passes up a ramp 39 so that the weight of the tension member, which comprises a central chain member having flights at each side, presses the flights slightly into the material to cause it to slide along the bottom 11. The flights may have a serrated lower edge to increase frictional grip on the material. The material is discharged at a plurality of intermediate discharge sections 16 and a final discharge section 17. Each section 16 has an opening 52 the after edge of which comprises a curved plate 47. When the material in a receiving bin 49 piles up to the opening 52 at its natural angle of repose the gently curved portion 48 of plate 47 prevents any tendency to force more material through the opening 52. The final discharge section 17 has bent out side walls 55,56 to increase the trough area whereby to ensure complete discharge of the material through the opening 54. Beyond the end roller 20 which is driven the tension member passes around an upper roller 21 from which it hangs in a catenery portion 27 for a part of the return run so that its weight provides tension, the remainder of the return run being supported on a guide 28 carried by inverted U-brackets 53 supported on angles 57 secured to the side walls of the casing 10. The conveyer may be inclined up to 60-70 degrees and still convey in the same manner, the reduction in effective weight of the tension member being compensated by increased packing effect of the material.
