Title: Improvements in weighing apparatus
IPC: G01G1/00
Filed: 1925-04-07
Abstract: 244,320. Wollaston, H. J. Buchanan-. April 7, 1925. Addition to 234,935. Pendulum-weight apparatus. - Relates to a modification of the weighing-apparatus described in the parent Specification, in which the relative motion between the eccentricallyweighted, counterbalancing roller a and the supporting surface or surfaces r is limited to a rolling motion by means of guiding bands or cords m<1>, m<2>, Fig. 3. The bands are attached to the supporting body and to surfaces of the roller which are parallel to, but do not form parts of. the rolling surfaces, the arrangement being such that the bands are not stressed by the load or by the weight of any part of the balance. The goods pan h is supported by a cord passing over a pin k projecting from one end of the roller. The pin k is detachable from the roller and mav be inserted in any one of a series of holes l. The stability of the pan h is maintained by a counterweight i. The weight of the load is indicated by a pointer j suspended from the pin k, a series of scales s<1>, s<2> corresponding to the holes l being provided. In a modification, Fig. 1, the goods pan h is arranged to one side of and below the roller a, and is suspended from two parallel arms projecting from the roller, the unsymmetrical arrangement causing an upward force on one arm and a downward force on the other. The supporting pins are carried by sliders d adjustable along the arms. The pendulous resistant depends below the roller a and is adjustable along its supporting rod, weight scales s<1>, s<2> corresponding to different positions being provided.
Patent GB-682797-A (GB)
Title: Method of fractionating fatty oils
IPC: C11B7/00
Filed: 1950-04-14
Abstract: Fatty oils are separated into fractions of relatively saturated and relatively unsaturated homogeneous triglycerides by simultaneous inter-esterification and extractoin with a selective solvent at such a temperature that two liquid phases are formed. Inter-esterification (the effect of which is to increase the proportion of homogeneous triglycerides in the oil and reduce the proportion of mixed triglycerides) may be effected by treating the oil with a suitable catalyst, e.g. a polyhydric alcohol such as ethylene glycol, propylene glycol, glycerol, pentaerythritol, mannitol or sorbitol, or a polyhydric alcohol and an alkali, e.g. sodium hydroxide, or an oxide or hydroxide of tin, cadmium or lead, or an alkali alcoholate, e.g. lithium, sodium or potassium ethylate.  The selective extraction may be carried out (1) with a solvent which dissolves most of the oil at the operative temperature but separates selectively as a liquid phase the saturated triglycerides present or produced in the oil, or (2) with a solvent which has only a low solvent power at the operative temperature and dissolves only the unsaturated triglycerides.  In case (1), the process may be effected at a gradually falling temperature, with continuous or periodic removal of the raffinate, whereby first the saturated triglycerides and then triglycerides of fatty acids with only one double bond are caused to separate from the mixture.  Suitable solvents for use in this way are ethylene glycol monomethyl or monoethyl ether and nitroethane.  In case (2), the process may be effected at successively increasing temperatures to extract in turn the most unsaturated triglycerides and then triglycerides of an increasing degree of saturation. Suitable solvents for use in this way are nitromethane, acetonitrile and trimethyl phosphate.  In an example, a solution of sodium methylate in methanol is added to a mixture of soya oil and ethylene glycol monomethyl ether, and the mixture is allowed to stand for 2 hours at 50 DEG C.  A layer of saturated triglycerides separates and is removed, and the residual mixture is cooled to 45 DEG C and allowed to stand for 4 hours, whereupon a layer of less saturated triglycerides separates and is removed.  The process is repeated at 35 DEG C and 25 DEG C, the separated layers being removed in each case.  In another example, a raffinate obtained from herring oil by extraction with furfural is treated with sodium methylate and extracted with acetonitrile, the extraction being repeated three times with intermediate agitation for two hours.  Other oils which may be treated are cotton-seed, peanut, olive, palm, sunflower, sesame, rapeseed, poppy-seed, linseed, perilla, Chinese-wood, whale, sardine, shark and fish-liver oils and dehydrated castor oil.

Title: Improvements in or relating to continuous molding machines
IPC: B29C48/05
Filed: 1945-04-18
Abstract: 629,344. Moulding rubber insulation on wire. BENBOW, B. W. April 18, 1945, No. 9749. [A Specification was laid open to inspection under Sect. 91 of the Acts, June 27, 1947]. [Class 87 (ii)] [Also in Group XXXVI] Relates to a machine for moulding on a wire an insulating sheath of rubber which may be allowed to stay on the wire or may be taken off to form a sheath, Figs. 11 and 12, which has a channel 141 to receive a conductor and a series of spaced openings 143 to allow spaced conducting teeth on a trolley to contact with the conductor, the latter being inserted through a longitudinal slit 142 which is then suitably clamped. The machine comprises a heated moulding and vulcanizing wheel 10 having one or more mould cavities 42 into which rubber is pressed around wires 12 located in the cavities. The pressure is applied by an endless metal band 11 which passes around pulley wheel 23, wheel 10, pulley wheel 25, back to tensioning pulley wheel 24 and so on to pulley wheel 23. Preformed rubber stock 14 is fed to the band as shown in Fig. 1a and is carried by the band around wheel 23 and into the nip formed between the band and moulding wheel 10. As shown, the stock consists of five U-shaped rubber strips, which are moulded around five wires, and these strips are guided on the wheel 23 by spaced fingers 102. Means for pressing the strips against the band to effect feeding of the strips comprises rollers 111, 112, which are journalled in spaced stationary fingers extending into the nip. The five moulding cavities are formed by rings 37...40 clamped or welded to the wheel 10. The wires 12 are endless and are fed into the mould cavities, where they seat on spaced teeth 43 on the rings 39. To ensure proper seating of the wires, they are fed to the wheel 10 over a roller (Fig. 3, not shown) which is oscillated to give them a small lateral movement. The moulding wheel is heated to cure the rubber. The heating may be electric, or as shown, steam is introduced into a chamber 46, Fig. 6, in the rim of the wheel by pipes 47. Condensed water is drained by pipes 52 through valves 54 which are opened as they pass a cam 57 adjustably mounted on the wheel bearing. The cured sheaths then pass over the wheel 25 and separate from the band 11 which returns to the wheel 24. The sheaths pass through a chamber where they are cooled by a water spray and then between rollers over fixed knives which cut the slits 142. They are then stripped from the wires 12 which pass over an idle pulley and back to the wheel 10. To mould the sheaths directly round the wires, the slitting knives are dispensed with and the wires are supplied to the wheel 10 from a reel. The wires may have projections to assist the bonding of the sheaths to them. As the moulded sheaths leave the cooling chamber they may be trimmed as by suitably placed grinding wheels. The machine is driven by a motor 59, and a motor 60 is used to drive it, through a clutch 68, at a higher speed for setting up. Specification 629,376, [Group XXX], is referred to.

Abstract: 526,920. Separating biscuits from conveyers. CARR & CO., Ltd., and CARR, R. N. March 29, 1939, No. 9781. [Class 78 (i)] Biscuits which stick to the trays after leaving the oven are loosened therefrom by a mechanical tapping-mechanism. As illustrated, the trays 4 carrying the biscuits 5 are carried through the oven on trains of trucks or trolleys 1 forming conveyers. On leaving the oven, the wheels 2 of the trucks momentarily raise the arm 9, thus rotating shaft 7 and the attached arms 8, 10. The counterweight on arm 10 then causes arm 8 to strike the surface of the pan 4. A cover-plate 11 prevents the biscuits from rising far from the surface of the band and re-directs them to the surface. As modifications, the cover-plate may be padded on its under side and may comprise an endless band travelling in the same direction and at the same speed as the biscuits. In cases where the conveyer comprises an endless band instead of a train of trolleys, the tapper may be driven from a moving part of the conveyer mechanism.
