Title: Improvements in methods of and means for treating fish, whale flesh and the like
IPC: A23B4/03
Filed: 1934-10-29
Abstract: Fish, whale meat, waste butchery products, and like materials having a comparatively high content of fats and oils are preserved, and prepared as a food for animals by drying by hot gases to a moisture content of 20-30 per cent by weight, reducing the fat and oil content to an amount insufficient to produce deterioration during storage, e.g. 10 per cent, and then drying to a moisture content of 8 per cent or less.  The drying is preferably effected at not above 70 DEG  C., and may be carried out in a rotating drum through which are transversely passed the hot gases which may be obtained by complete combustion of a fuel such as coke or wood, the gases being cooled and cleaned before use. The reduction of the percentage of fat and oil present may be obtained by removing the fats and oils, e.g. by pressing while the product is still warm, or by adding non-fatty materials such as dried grasses, clover and alfalfa which absorb the fats and oils, generally 40-60 per cent of these substances being added.  The added materials may first be finely divided by grinding &c., and after addition the mixture may be ground.  The reduction of the fat and oil content may be effected by a combination of both above methods.ALSO:Fish, whale meat, waste butchery products, and like materials having a comparatively high content of fats and oils are preserved by drying by hot gases to a moisture content of 20-30 per cent by weight, reducing the fat and oil content to an amount insufficient to produce deterioration during storage, e.g. 10 per cent, and then drying to a moisture content of 8 per cent or less.

Patent GB-267234-A (GB)
Title: Improvements in and relating to the extraction of juice from sugar cane
IPC: C13B10/02
Filed: 1925-12-14
Abstract: 267,234. Morgan, W. H. Dec. 14,1925. Extracting sugar.-In the extraction of the juice from sugar cane, the canes are cut into short sections which then are shredded longitudinally during longitudinal movement thereof between relatively movable blades to produce a fibrous finely-shredded absorbent mass from which the juice can be extracted 'by expression or diffusion. The shredder is preferably constructed as described in Specification 266,841, [Class 5 (i). Farmyard &c. appliances], and bv arranging that the shreds and the juice are confined during the shredding, juice liberated therein is reabsorbed by the spong-like absorbent mass. In the example described, the canes are delivered by a travelling cane 5 to the hopper 6 of a multiple saw 7 where they are cut into sections of about 6 in. in length. The sections are passed by a conveyer 9 to a shredder 10 which consists of two stationary discs having radially-disposed shredding blades on their inner surfaces with which similar blades on opposite sides of a central rotating disc coact. The shaft of the central disc may be driven by one or two motors; where two motors are employed, one at each end, each may be capable of driving the disc alone. The spaces between the discs are of such a size that the cane sections enter and are guided into position so as to be substantially radial to the shaft during shredding. The shredded cane passes to a. series of expression rollers 16, from the last of which the bagasse. now comparatively dry, may be blown as fuel into the fire-box of a. boiler by a fan 18. When the juice is extracted by diffusion it is easily removed from the cells, which are broken in the shredding, and the wax and other impurities adhere to the fibres giving a purer extract.

Title: A method of refining raw sugar melts and affinations and other saccharine fluids in the sugar industry
IPC: C13B20/12
Filed: 1925-12-14
Abstract: 267,242. Naugle, J. J. Dec. 14, 1925. Purifying saccharine liquids.-Raw sugar or saccharine liquids in the sugar industry are refined by treating the raw sugar melt or the liquid in batches, preferably without previous filtration or defecation, with vegetable carbon which is derived from carbonized lignin residues according to Specification 267,240 or 267,241, [both in Class 90, Non-metallic elements]. The melt or liquid is subjected to two or more treatments with the carbon on the countercurrent system, the impure melt or liquid meeting the more nearly spent carbon and the purest melt or liquid being treated with the most highly activated carbon. The number of treatments is determined by the degree of purity desired. Filtration follows the final treatment. The spent carbon is revivified for further use in an electric furnace of the form described in either of the above-mentioned Specifications. In the example described, raw sugar which may be of about 96 per cent purity is washed, for example in centrifugals, and the washed sugar of about 99 per cent purity melted and about one to two per cent by weight of the decolourizing carbon of the weight of sugar in the melt added. The carbon removes most nf the gums, pectins, and other colloidal substances, together with a high percentage of the mineral substances dissolved or in suspension in the melt. After treatment with the carbon on the countercurrent principle in 2-4 or more batches the melt is filtered, and on being sent to the pans yields at least 4 or 5 successive crystallizations of white granulated sugar. In treating the liquors obtained on washing the raw sugar about 4-10 per cent of the carbon by weight relative to the amount of sugar therein is added. The sugar from these wash liquors, which is generally light yellowish in colour, may be mixed with the sugar obtained from the raw sugar melts in such proportions as to give a standard white granulated' sugar. The carbon is revivified by heating in the electric furnace to about 350-150‹ F. for 15-60 minutes, preferably 30 minutes, until the impurities are burned away. Little or no combustion of the carbon itself takes place as it does not commence to burn until about 600-750‹ F. The furnace has controllable means for supplying air or steam or both. The carbon is capable of repeated revivification. Reference is made to defecation of the raw sugar melt with acid calcium phosphate, and to its prefiltration, using such filtering media as paper pulp, diatomaceous earth, sawdust, charcoal &c. Specifications. 155,609 and 163,505 are referred to.

Patent GB-740274-A (GB)
Title: Process of preparing an alkyl or aryl tin compound
IPC: C07F7/22
Filed: 1953-11-16
Abstract: Organo tin compounds are produced by reacting RX, where R is alkyl or aryl and X is halogen, with magnesium and the compound RySnX4-y, where y is 1 to 3, according to the equation <FORM:0740274/IV(a)/1> where n is 1 to 3 and (y+n) is 2 to 4.  Compounds of formula R2SnX2, R3SnX and R4Sn may be produced. The reagents may be mixed in the presence of a catalyst, e.g. ether, in minor proportion so as not to serve as a major solvent, and in the presence of an inert hydrocarbon solvent, e.g. hexane, octane, decane, xylene or toluene.  A small amount of ethyl bromide may be added to activate the magnesium.  If desired, the process may be based on the following sequence: <FORM:0740274/IV(a)/2> in which one mol. of R2SnX2 produced by re-action (b) may be taken out as product while the other is used in reaction (a) for the next run, or, if R4Sn is the desired product, half that produced in reaction (a) would be removed, the remainder being used in reaction (b).  In an example butyl chloride is reacted with magnesium in toluene in the presence of ethyl bromide and ether. Then a blend of butyl chloride, toluene and butyl tin trichloride is added slowly.  The toluene is stripped and the magnesium chloride removed by solution in water to leave tributyl tin chloride and tetrabutyl tin, which may be separated by vacuum fractionation.

Abstract: 792,659. Wire strainers. ECROFNIER & PARTNERS, Ltd. Oct. 28, 1954 [Nov. 17, 1953], No. 31824/53. Class 45. [Also in Group X]  In a wire strainer especially for straining the wires of pre-stressed concrete, and comprising a barrel 10 having a stop 14 at its forward end, a cylinder 11 reciprocated within the barrel by a spur wheel 26 and having a bore 12 for the wire, and a one-way gripper A mounted at the forward end of the cylinder, a projection 23 on the gripper engages the stop when the barrel is moved rearwardly of the cylinder to cause release of the gripper. One end of the wire 13 is held in a stop C, Fig. 3, and the remainder of the wire is passed through the concrete mould to a fixed one-way gripper B, from whence it is threaded into the strainer through the stop 14, through the gripper A and through the bore 12. The spur wheel engages a rack 25 on the cylinder and is driven through a ratchet and pawl (not shown) by rocking a torque wrench 31 which slips or registers when a predetermined tension has been applied to the wire. During rearward movements of the cylinder the gripper A tensions the wire, whilst during forward movements of the cylinder the wire is released from the gripper A, the gripper B acting to maintain the tension of the wire passing through the mould. After the predetermined tension has been applied to the wire the gripper A is released by pulling the barrel away from the abutment 30 to bring the stop 14 into contact with the projection 23. The release of the wire may be facilitated by moving the cylinder forward by means of a bar 35, Fig. 3. An indicator showing the amount the wire has stretched may be provided on the barrel. The gripper A may be replaced by grippers of different sizes. Fig. 9 shows an adaptor fitted to the forward end of the strainer, and which permits the one-way gripper B to be replaced by a standard wedge grip acting as a one-way gripper. The forward end of the adaptor engages the wedge grip D the wedges of which are engaged by a spring pressed plunger 45 sliding the body 40 of the adaptor. Specification 792,658 is referred to.
