Title: Improvements in or relating to Steam Superheaters.
IPC: F22G5/20
Filed: 1918-05-22
Abstract: 126,817. Babcock & Willcox, Kemnal, J., and Henry, J. May 22, 1918. Fire and smoke tube superheaters; controlling superheat; overheating of tubes, preventing.-A superheater is fitted on the outlet side with a regulator valve of the piston type. The regulator valve G arranged above the saturated-steam header B controls the passage of steam to the engine supply-pipe K. When the valve is closed, the steam flows through the regulator casing back into the boiler steam-space. The valve is operated by a hollow spindle H<1> having a side opening I controlled by an internal spindle J allowing saturated steam to flow through the spindle and mix with the superheated steam. The internal spindle is slotted at its end, so that, by bringing the slot in register with the opening I, a small quantity of steam passes to the back of the valve to equalize the pressure thereon, and flows through the supply pipe to warm the cylinders when the engine is standing. The superheating elements F are expanded into auxiliary headers E connected to the main headers A, B by short tubes D. In a modification, a number of superheating elements are arranged with each of several large fire-tubes.

Title: Bearings
Inventor: FORRESTER PETER GARNETT
IPC: C23C4/08
Filed: 1957-03-15
Abstract: A bearing is made by roughening the bearing shell as by shot blasting or etching, tinning it, and then applying white-metal (i.e. Sn-base or Pb-base alloy) thereto by spraying, the tinned surface being treated with an oxide-removing flux immediately prior to, or during, the spraying.  The flux-treatment may be effected by (1) moistening the surface with HCl prior to spraying, (2) including HCl gas in the spraying gas, or (3) including NH4Cl powder in powdered white-metal used for spraying.  The bearing may be finally subjected to mechanical working and heat-treatment.

Abstract: 941,024. Index tabs. SNOWDEX Ltd. Jan. 31, 1962 [March 13, 1961], No. 9157/61. Heading B6E. An index tab comprises the combination of a channel-shaped base 1 adapted to be secured to a suspension file or folder, an information &c. card 7 which is placed on the base 1, and a transparent cover 6 which is detachably secured on the base 1 by the engagement of projections on the cover with projections 8 on each leg of the base, relative movement in one direction between the cover and base being prevented by a stop means. The legs 1a, 1b of the base 1 have holes 2 whereby they can be secured by rivets to one side or fold of a suspension folder substantially in a vertical position. Projections 8 are formed by cutting the legs of the base 1 on three sides and bonding the material outwardly, and these projections are slidably engaged by infolded ends 9 of the cover 6. In order that documents laterally slid from the suspension folder may not catch on the inside projection 8, protuberances 12 are pressed out of the leg 1a of the base 1 to cause the documents to ride over the projection. A strap lip 10 on the back of the base 1 prevents the cover 6 being dislodged, in a downward direction, from the base 1. The base 1 can be of metal or plastics material. The suspension folder is suspended by bars as described in Specification 937,052.

Title: Improvements in or relating to the purification of effluent from distilleries
IPC: C12N1/16
Filed: 1947-04-08
Abstract: 628,864. Treating waste effluents. CHARLTON, J. April 8, 1947, No. 9351. [Class III] [Also in Group VI] Effluent from distilleries using molasses as a raw material passes from a tank 1 to a centrifuge 2 which separates suspended matter and then to a storage vessel 4, whence it passes via a heat exchanger 97‹F. 5 in which it is cooled, to about to fermenters 6 and 7 in succession. In the fermenters there are added live food yeast organisms such as ammonia or its salts organisms such as ammonia or its salts (excluding ammonium sulphate) and orthophosphoric acid or its salts. The proportion of live organisms in the fermenters is preferably maintained about 8 per cent by weight (measured in the wet condition) of the effluent; the ammonia (or salt) is just sufficient to keep the formal titration below 0.5, and the phosphorus compound is added in such quantity that the resulting food yeast (when dried) comprises about 1.8 per cent to 2 per cent of phosphorus, while the effluent is materially free from phosphates. Compressed air at 15 lbs. per square inch is continually forced through the fermenters at a rate sufficient to ensure the using up of all the nitrogenous organic matter in the liquid. The effluent then passes through a foam breaker 8 to a surge tank 10, any froth being returned to the fermenter 6, and thence to a separator 11 from which part of the food yeast cream obtained is passed back to the fermenters, and the remainder to washing separators 13, 15. The product is finally dried on the rollers 18 and ground in a roller mill 19. The food yeast organisms may be provided by pseudo yeasts such as Torula utilis and/or Moulds such as Monilia candida and Candida arborea in the sub-group monilia.
Patent GB-572670-A (GB)
Title: Improvements in or relating to the manufacture of synthetic plastic materials
IPC: C08F257/02
Filed: 1941-07-23
Abstract: Thick, clear, bubble- and strain-free masses of polymeric synthetic resinous material, suitable, e.g. for optical purposes, are obtained by swelling a mass of a "polymer of reduced solubility characteristics," in massive or powder form, by adding a normally liquid polymerizable organic compound capable of swelling said polymer and thereafter polymerizing the adsorbed monomeric compound. A "polymer of reduced solubility characteristics" is that form of product obtained by copolymerization of a normally liquid monomer with a cross-linking agent which product is insoluble in, but will swell when treated with a solvent, e.g. benzene or a liquid monomer, e.g. styrene. Specified monomeric liquids are vinyl compounds, e.g. styrene and methyl methacrylate, and indene; specified cross-linking agents are divinyl benzene, divinyl ether, divinyl sulphite, divinyl acetylene, acrylic anhydride, methacrylic anhydrite, crotonic anhydride, polyhydric alcohol esters of acrylic, alpha-substituted acrylic and crotonic acids and vinyl esters of dicarboxylic acids. The swelling liquid may contain a cross-linking agent in an amount sufficient to produce, from the monomer, a polymer of reduced solubility characteristics and the product may be subjected to further swelling and polymerization treatments; alternatively, the amount of cross-linking agent in the monomer used in the swelling stage, or final swelling stage, may be so increased as to convert the monomer to an insoluble and non-swelling material.  Examples are given of the production of copolymers of styrene and divinyl benzene and their treatment with styrene, methyl methacrylate and styrene containing divinyl benzene.  Specification 540,940, as open to inspection under Sect. 91 of the Acts, is referred to.

Title: Continuous process for the thermal decomposition of salts of ricinoleic acid
IPC: C07C51/377
Filed: 1957-03-22
Abstract: The invention comprises a continuous process for the decomposition of alkali metal ricinoleates, in which a reaction product, obtained by heating an alkali metal ricinoleate in the presence of alkali and water (both in amounts at least equal to those stoichiometrically necessary for the alkaline fission of the ricinoleate) and of such consistency that on cooling it solidifies to a viscous to solid mass, is diluted under pressure, after the completion of the reaction, with a quantity of water such that on cooling to room temperature the diluted product remains mobile, releasing the dilute product from pressure, and separating sebacic or hydroxydecanoic acid or a salt thereof.  The catalytically active metals cadmium, lead, bismuth, or thallium or a compound or alloy of these may be present.  The original reaction mixture may contain up to 50% of water, and 1-7 times the quantity of alkali stoichiometrically required.  The reaction product may be diluted with at least its own weight of water, e.g. 2-5 times. In place of alkali metal ricinoleates, castor oil may be used, being first saponified and then decomposed.  Fatty acids, octanol-2 and octanone are also stated to be formed. Specifications 736,413 and 835,208 are referred to.
