Patent GB-606765-A (GB)
Title: Improvements in and relating to contacting gases or vapours with solids
IPC: C10J3/54
Filed: 1946-01-18
Abstract: The Provisional Specification describes a process for contacting gases and solids in which the solid is maintained in the fluid state by the upward passage of a gas, and is constrained to flow in a substantially horizontal direction.  The solids may be treated with different gases or under different conditions by flowing through a series of vessels or through compartments in a single vessel.  The gas is led into the base of the vessel and distributed by perforated plates which may carry granules or spheres which are not displaced by the gas stream.  The process may be used for the production of water-gas from coal (see Group XII) or for the catalytic treatment of hydrocarbons, followed by removal of carbon from the catalyst by means of oxygen.

Abstract: 373,209. Building-motions for ring spinning-frames. PEARSON, G. W., 223, Central Block, Lowell, Massachusetts, U.S.A. -(Assignee of Cox, W. ; Lowell-Lawrence State Highway, Methuen, Massachusetts, U.S.A.) Jan. 20, 1931, No. 1886. Convention date, Feb. 4, 1930. [Class 120 (ii).] In a ring spinning or doubling frame the ring rail is traversed and the bobbins or bobbin carriers are also traversed, on non-reciprocating spindles which may be stationary or may rotate, whereby larger yarn packages may be wound. The two reciprocating motions may be obtained from a Scaife builder motion by means of a pivoted lever, one end of which is connected to the usual lifter rod actuating the bobbin rail, and the other end to a rod actuating the ring rail. The fulcrum of the lever may be adjustable so as to obtain different relative movements of the two rails. A fixed spindle rail B, Figs. 7 and 8, carries stationary spindles C. A bobbin rail F having bobbin carriers H driven by bands 51 is raised and lowered by lifter rods 62 operated by a Scaife builder motion. The ring rail lifter rod 72 is actuated from the rod 62 by a lever 8 adjustably pivoted at 7. Each lifter rod carries adjustable buttons 65, 75, Fig. 10, which engage the lever 8, and adjustable buttons 69, 79 which engage the rails and, if desired, adjustable stops 44, 45, whereby any desired relative movements of the bobbin rail F and ring rail 0 may be obtained.

Filed: 1962-01-18
Abstract: 961,501. Supply circuits for discharge tubes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. April 2, 1963 [Jan. 18, 1962], No. 1923/62. Heading H2H. [Also in Division H3] The heater supply to a thyratron is regulated inversely to its anode current so that the sum of the anode and heater supplies is limited. The primary of a transformer T3 which supplies the heater is series - connected across the mains supply with a booster transformer T2 whose secondary is also fed from the mains supply through a regulator comprising a variable choke T4, the position of its tapping being controlled by a servomotor M1 having field coils F1, F2 controlled respectively by switches P1/1, P2/1. The output from the choke T4 is also supplied, through transformer T1 and rectifier bridge RCT, to one coil L2 of a differential moving coil relay MCR whose other coil L1 is fed from a resistor R connected in the earth return lead of the HT supply for the thyratron. Normally, the armature M of the relay MCR lies midway between the fixed contacts S1, S2, but when the ratio of anode current to heater supply departs from a predetermined range the armature M engages one or other of the contacts S1 S2 to close the corresponding switch P1 or P2/1 (through energization of the coil P1 or P2), thus causing motor M1 to alter the setting of the heater regulator T4 until balance is restored.

Title: Improvements in or relating to a process for extracting fatty materials by the use of solvents
Inventor: CHAMPAGNAT ALFRED
IPC: C12N1/02
Filed: 1963-01-18
Abstract: An extraction process in which fat is extracted from fat-containing material, e.g. seeds, but especially micro-organisms such as yeasts, moulds and bacteria, comprises treating the material with a pulsed stream of a solvent such as propane, butane or hexane. Micro-organisms which are suitable for extraction are those yeasts, moulds or bacteria which have been cultured on a petroleum fraction which consists wholly or partly of straight-chain hydrocarbons, preferably in the presence of oxygen and an aqueous nutrient medium. In particular, when the substrate is a waxy gas oil, the residual oil obtained after the micro-organisms have been removed for fat extraction has an improved pour point.  Many suitable yeasts, moulds and bacteria are specified, but the yeast Candida lipolytica is preferred.  As shown, the yeast "cream" phase obtained by centrifuging the fermented oil is placed between plates 1 of extractor 2 and solvent, e.g. hexane, which is <FORM:1059890/C4-C5/1> pulsed by piston 6, passed upwards from tank 3 by line 5 through the mass.  The extract is passed to distillation column 9, solvent vapour leaving by 10 being condensed in condenser 11 and returned to tank 3, while extracted fat leaves by line 13.  The extracted material is preferably dried after extraction.
