Abstract: 650,212. Ironing-machines; rollers. TULLIS, Ltd., D. & J. Dec. 15, 1948, No. 32419. [Classes 42 (ii) and 138 (ii)] Resilient padding for a roller 1 of an ironing machine comprises a plurality of spring-carrying strips 2, each wound around the roller 1 and cover strips 7 wound around the spring-carrying strips 2, one of which is attached to the roller by the same screw 4 which attaches the respective spring-carrying strip to the roller and a wire cloth 13 lapped upon the strip assembly. Springs 3, Fig. 2, are wound in pairs and threaded on to the strips 2, the ends of which overlap and are fixed to the surface of the roller 1 by the screw 4 which engages a tapped hole 6 in the roller 1. Each screw 4 also attaches one end of the strip 7 to the roller. Each strip 7 covers the springs attached to a strip 2 and the ends of each strip 7 overlap and are held together by a clip 10. The free end 9 of every second or third strip 7 is bent to form a hook 11, Fig. 3, which engages a plate 12 attached to the wire cloth 13. The remaining ends 9 of the cover strips are bent back against the clip 10. The strips 7 are wider than the strips 2 and are located by notches 14 which engage between the springs.

Patent GB-486168-A (GB)
Title: Improved method for obtaining the suprarenal cortex hormone
IPC: A61K38/22
Filed: 1936-11-27
Abstract: Suprarenal cortex hormone is purified by adsorbing it from a solution in a water-immiscible organic solvent, separating the adsorbate and recovering the homone by elutriation.  Suitable water-immiscible solvents are petroleum ether, ligroin, cyclohexane and benzene, adsorbents are "Frankonit" (Registered Trade Mark), fibre alumina, fullers earth, kaolin, animal charcoal, and sugar.  The adsorbate may be elutriated with dioxane, acetone or a mixture of pyridine and methyl alcohol, all containing water, or with anhydrous solvents such as mixtures of methyl alcohol and chloroform, acetone and benzene, or acetone and chloroform, or water may be used.  The crude hormone used as starting material may be prepared by extracting suprarenal glands with alcohol, evaporating the extract and re-extracting it with benzene, and if desired evaporating this extract and extracting the residue with acetone which is finally removed by evaporation. Reference is made to processes for adsorbing impurities from alcoholic solutions of the hormone by means of a base exchange body, or for adsorbing the hormone from aqueous or aqueous-acetone solutions by means of charcoal, followed in some cases by elutriation of the adsorbate with aqueous pyridine or phenol.

Filed: 1957-10-18
Abstract: 1,009,940. Seals. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Sept. 19, 1958 [Oct. 18, 1957], No. 32691/57. Heading F2B. A gland 12 for preventing leakage of gas from a compressor casing 13 in which is situated an impeller 11 driven by a shaft 10, comprises a pair of optically flat annular plates 14, 16, the plate 14 being secured to the shaft through a disc 15 and the plate 16 being mounted on a plate 17 connected to the casing 13 by a bellows 18. The plate 17 is supported by a spring 42 connected between a ball 43 and a stud 46. The flat surfaces of the plates 14, 16 are urged against each other by springs 24 acting on the plate 17, the surface of the plate 14 being plain and the surface of the plate 16 having an annular groove 22 into which a bearing gas is introduced through channels 21. Spiral grooves 23 extend from the groove 22 so that when the shaft 10 rotates the bearing gas is drawn to the outer periphery of the plates 14, 16 and holds the plates apart, this gas entering the casing 13. The bearing gas prevents gas from the casing flowing in the reverse direction across the opposed faces of the plates and escaping to atmosphere. The gas is supplied to the channels 21 by a ring manifold 39 through flow restrictors 40, the restrictors enabling the pressure of the bearing gas as to be increased for a slow rotation of the shaft. In a modification the groove 22 is not continuous but composed of a number of arcuate sections each supplied through a channel 21.

A liquid pressure actuated pump for injecting methanol into a fuel system comprises a double acting piston and cylinder arrangement controlled by a liquid actuated shuttle valve 32. A stepped cylinder 34 houses a piston rod 35 and stepped piston 36, 37. Methanol enters pumping chambers 45, 46 via passages 47, 48 and is delivered via passages 25, 26. In the position shown liquid pressure from a pipe 27 passes to the end 44 of cylinder 34 via passages 74, 73, 62, 75 and 75<SP>11</SP> to move the piston assembly to the left. Shuttle valve 32 is maintained in the position shown by the pressure differential set up by pressure liquid passing to pipes 55 and 56 via a port 81, bore 68 and passages 69 and 72, pipe 55 being closed by piston rod 35 and pipe 56 connected to an outlet 58 by a groove 60. On movement of the piston assembly to the left groove 60 moves out of alignment with pipes 56 and 58 and valve 32 is then maintained in position by the passage of liquid from pipe 56 to an outlet 79 via a passage 78. At the end of the stroke groove 60 is aligned with pipes 55 and 57 so that valve 32 is moved to the left. Pressure liquid then enters the end 54 of cylinder 34 via bore 68 and passages 62, 76 and 76<SP>1</SP> to move the piston assembly to the right for the suction stroke. The pressure liquid outlets lead to the low pressure side of a fuel pump, Fig. 1 (not shown). Fuel under pressure serves as the pressure liquid.

[Class 37] The electrolyte in an electrolytic condenser comprises a concentrated (i.e. containing not more than 15 per cent of water) organic acid of the aliphatic series, other than oleic acid, the acid being in the liquid state at least when it is introduced between the electrodes. A cellulose ester or ether-e.g. cellulose acetate or nitrate, or ethyl, methyl or benzyl cellulose, may be added to the acid as a thickening agent, and a resistance modifying salt, such as ammonium borate, may also be added. Acetic acid is preferably employed, but propionic, butyric, isobutyric, valeric, isovaleric, diethylacetic, acrylic, crotonic, lactic, dihydroxypropionic, hydroxyacrylic and ethylene lactic acids are also specified. The electrodes may be of aluminium, tantalum or magnesium and may be separated by porous spacers, e.g. of cheesecloth or paper, which may be perforated. The condensers may be in roll or stack form, and after assembly are immersed in the acid heated to 75 to 100‹ C., the condenser being subjected to intermittently or continuously applied voltage during the latter part of the immersion. After this treatment, the condensers may be placed in a container and sealed with wax, or they may be dipped in molten wax before being placed in the container. Specification 435,300 is referred to. The Specification as open to inspection under Sect. 91 comprises also the use of acids of the aromatic series, such as phenol and cresol, as electrolytes.

Title: Manufacture of combustible gas

Abstract: 817,052. Carburetting gas. HUMPHREYS & GLASGOW Ltd. Oct. 13, 1955 [Nov. 16, 1954], No. 33200/54. Class 55 (2). In a process for enriching a combustible gas the gas is contacted directly with an oil which contains a minor proportion of readily volatile constituents under conditions such that the volatile constituents are transferred to the gas, the gas being free of impurities, e.g. tar, which would be scrubbed from the gas and contaminate the residual oil. The oil may be a crude petroleum oil or a wash oil which has been used in gas debenzolizing or is being used for removal of naphthalene from the gas. The gas enriched may be blue water gas, a gas made by oxidizing methane, carburetted water gas or oil gas, the gas in the latter two cases being cooled and debarred before contact with the enriching oil. In the Figure, hot gas from a catalytic cracking chamber (not shown) is passed through scrubbers 11 and 13 in which it is sprayed with water and then through a scrubber 15 where it is sprayed with gas oil to remove naphthalene and finally into an enriching scrubber 17, crude petroleum oil being sprayed downwards over a packing such as Faschig rings. Oil from the base of the scrubber is drawn off through a settling tank 20 for use as gas-making oil or burner fuel for an oil-gas plant. In a modification scrubber 17 may be omitted and the wash oil in the naphthalene scrubber may have incorporated with it a volatile enriching medium such as light petroleum or a petroleum oil containing easily volatilized constituents.
