Title: Improvements in or relating to treating fatty oil
IPC: C11B3/02
Filed: 1954-04-22
Abstract: Gum-containing fatty oils are treated so as to release the oil entrained in the gums, prior to refining, by admixing with the oil sodium hydrosulphite in aqueous solution in an amount at least 0.01 per cent by weight of the oil.  The amount is preferably 0.05 to 0.125 per cent by weight of the oil.  The amount of water in the solution desirably represents 0.2 to 2.0 per cent by weight of the oil.  The oil is then refined, preferably using aqueous caustic soda of at least 20 DEG B<\>ae.  The caustic soda is preferably used in amount just sufficient to neutralize the free fatty acid content of the oil.  Temperatures of 120 DEG -160 DEG F. are satisfactory. The soapstock may be removed by gravity settling or centrifugal separation.  The conditioning treatment and first refining step may be followed by an additional refining treatment with caustic soda of at least 20 DEG B<\>ae.  The whole of the process may be carried out continuously.  The oils treated may comprise animal, vegetable and marine oils.

Title: Improvements in or relating to the production of photographic colloid relief images
IPC: G03C5/315
Filed: 1940-07-16
Abstract: 542,606. Photographic colloid relief images; colour photography. HOW, H. E. July 16, 1940, No. 11740. [Class 98 (ii)] An unhardened colloid layer containing a photographic silver image and supported on a film as of cellulose acetate or nitrate, or on paper or glass, is converted into a hardened colloid relief on a cellulosic support by applying to it a wet, water-permeable cellulosic film, drying, treating the assembly first with an aqueous bath which penetrates through the cellulosic film and hardens the colloid in dependence on the silver image, and then with an aqueous bath which dissolves the unhardened colloid, and thereafter separating from the original support the cellulosic film bearing the colloid relief so formed. Any silver salt remaining may be fixed out. If the colloid is gelatin, the hardening may be effected by an aqueous solution of cuprammonium chloride and chromic acid, or of cupric chloride and potassium bichromate. The cellulosic film may be of the material known under the Registered Trade Mark " Cellophane ", ethyl cellulose, cellulose glycollate, or cellulose lactate. In order to avoid difficulty in removing the relief from the original support the image-bearing colloid layer may be produced from an emulsion layer which is either abnormally thick, or contains a filter dye such as tartrazine, or is coated over a layer of plain unhardened colloid, so that the image does not extend entirely to the support. Colour transparencies may be produced by forming from each of a set of colour-record negatives a colloid relief on a cellulosic film, colouring the reliefs in the appropriate subtractive colours as by dyeing the colloid, or by colourdeveloping or developing and dye-toning the residual silver salt, and superimposing them in adhesive register, e.g. on a waxed glass plate, from which the assembly may be stripped, after soaking with glycerine, and mounted if desired on paper. Instead of being coloured and superimposed, the set of colour-record colloid reliefs may be used as dye-imbibition printing matrices. Dyed colloid reliefs produced according to the invention may be used as colour-correcting masks in multicolour processes, e.g. a colour-corrected printing negative may comprise a colour-record negative having superimposed in register therewith a positive colloid relief mask containing silver or a neutral dye produced as described from one or more different colour-record negatives. Specifications 340,605 and 357,548 are referred to.

Abstract: 512,077. Pneumatic railway systems., MERZ, F. April 22, 1938, No. 12133. Convention date, April 22, 1937. [Class 104 (ii)] [Also in Group XXXIII] A fluid-operated piston device for launching aircraft, conveying railway trucks or elevator cabins &c. comprises a lateral arm on the piston projecting through a slot on its cylinder, this slot being elsewhere sealed by a longitudinal ribbon which is caused to follow a smooth path defined by the surfaces of the piston and the arm, which arm is in the form of a longitudinal. web. The ribbon 5 may be crescent-shaped, Fig. 4. The tubular double piston 6, 6', of which three may be provided in parallel bores in a cylinder, the pistons being connected externally, transmits thrust to a central tube 8 connected by a web 10 extending through the slot 3 with the force transmitting member 9 which is linked by rods 13 with the launching &c. carriage 15 to be moved. The carriage is provided with brakes comprising metal sheets 37, Fig. 7, on the carriage, clamped between external jaws under air pressure and an internal member 41 either stationary or sliding a short distance. Air or explosive gas is admitted to move the pistons by a valve 24 operated by a piston 26 to which air is admitted by opening a valve 27; the valve 27 also operates a valve 42 to release the brakes. An adjusting valve 25 is gradually opened to its maximum extent by the motion of the carriage. At a certain point, a cam 29 actuated by the motion of the carriage opens a valve 28 admitting air to the piston 26 to operate the valve 24, closing the inlet 48 and opening the outlet 49. Immediately afterwards air or gas is admitted to the other end of the pistons which are brought to rest under this action and the action of the brakes at the outer end, the sliding member of which may close the air inlet and open the outlet at this end. To return the carriage to the launching end, the brakes at the other end are released and the adjusting valve at this other end throttled, and air is then admitted to move the pistons, which are stopped as before. A motor-actuated chain and sprocket device, afterwards brings the carriage back to the exact starting position.

Apparatus for the recovery of oil of high viscosity from a formation penetrated by wells comprises a steam generator, conduit for supplying steam under pressure to a first well or set of wells, a container for collecting oil, and conduits for supplying oil to the container connected to the first well or set of wells and to a second well or set of wells. The first well is subjected to a cycle of operations comprising steam injection, close-in, and oil production. The cycle is repeated until the steam drives the oil remaining in the formation, to the second well which is then produced. In a modification the generator is also connected by a conduit to the second well. In operation of the modification the first and second wells are both repeatedly subjected to the cycle, one well producing whilst the other is injected. When the steam injected to one well drives the remaining oil to the other well, steam is continuously injected to the one well and the other well is produced. The feed-water for the generator may pass through a heat-exchanger in the conduit leading oil from the producing well.
