Title: Improvements in or relating to compression refrigeration systems
IPC: F25B39/02
Filed: 1947-03-05
Abstract: 622,043. Refrigerating. LIGHTFOOT REFRIGERATION CO., Ltd., and SINCLAIR, W. R. March 5, 1947, No. 6267. [Class 29] In a compression refrigerating system in which the evaporator is of the flooded type, mixed or dissolved refrigerant and lubricant are continuously withdrawn from the evaporator 1 to an oil-separating chamber 3 in which the refrigerant is evaporated by applied heat and returned to the suction pipe 6 and from which liquid containing a high oil content is separately withdrawn. Mixed refrigerant and lubricant flows from the evaporator 1 through tube 2 and a non-return valve 4 to the oil-concentrating chamber 3, where it is heated by hot refrigerant liquid flowing in a coil 7a, and refrigerant is thus driven off from the mixture and is then sucked into the suction conduit 6 through a pipe 5. Lubricant flows from chamber 3 through a pipe 10. A draw-off pipe 10, adjustable in height, is described, (Fig. 4, not shown). The evaporator 1 comprises brine headers 1a and brine circulating tubes 13, the refrigerant entering at 9a and being constrained by staggered partitions 11, 12 to follow a tortuous path to outlet 2. In a modification, (Fig. 3, not shown), the evaporator drum 1 is divided by longitudinal partitions so that refrigerant fills the divisions successively.

Filed: 1947-03-06
Abstract: 622,053. Gas turbine plant. MASCHINENFABRIK OERLIKON. March 6, 1947, No. 6386. Convention date, April 15, 1946. Drawings to Specification. [Class 110(iii)] In a gas turbine plant for driving a vehicle in which the turbine driving the compressor is separate from the useful power turbine, the temperature of the working gas for the former turbine is variable independently of the speed and load conditions of the power turbine. On gradients, where an increased load is accompanied by a reduced speed of the useful power turbine, the load is taken by increasing the temperature at the compresser turbine inlet and thereby providing air at an increased pressure for the combustion chamber of the useful power turbine. The useful power turbine may be in series with the compresser turbine with reheating before the latter. Or, the two turbines and their combustion chambers may operate in parallel.

Filed: 1965-02-15
Abstract: In a process for the production of very pure chondroitinase, cells of Proteus vulgaris (N.C.T.C. 4636) are macerated with a solvent, filtered off and dried, the dried material homogenized in a buffer solution with a pH of about 7.0, incubated at this pH for a short time, the liquid phase separated and dialysed against water, the dialysed, cell-free extract mixed with an aqueous solution of a salt of yeast nucleic acid previously adjusted to a pH of about 7.4, the material which thereby precipitates re-suspended in water and dissolved by the addition of an aqueous solution of an alkali metal hydroxide until the pH is about 7.4, an aqueous solution of protamine sulphate added until the addition of protamine sulphate to a sample clarified by centrifuging no longer gives a precipitate, a slight excess of protamine sulphate then added and the solution as a whole dialysed against water, precipitated material removed, the supernatant liquid adjusted to a pH of about 8.0, cooled, clarified and again dialysed, the resultant clear solution finally being lyophilized. The powder obtained may be adsorbed on calcium phosphate gel and fractionally eluted with sodium acetate, or if it is desired to recover also the chondrosulphatase with which the chondroitinase is contaminated, the two enzymes may be separated chromatographically on DEAE-"Sephadex" (Registered Trade Mark).

[Class 51 (i).] In stoker mechanism p a r - ticularly for locomotives, in which the fuel is conveyed to a housing on the firebox by worm conveyers and fed to the firebox bv worm feeding means, a ledge is provided extending longitudinally of the worm feeding means to reduce back pressure upon the fuel column. Coal is fed from the tender by a screw conveyer 15 and delivered to a housing 13, 14 of increasing diameter where it rises to concave ledges 33 extending longitudinally parallel with the peripheries of two rotating worm feeders 27, 28. The ledges are eccentric to the axis of the feeders to prevent jamming of the fuel. The rising fuel spills over the ledges at 33a into the path of the outer ends of the spiral vanes of the feeders, which pass the fuel through the fire opening 12 over a blast chamber 34 to a distributing plate 35 from which it is scattered over the fire by jets of steam issuing from the blast chamber. The rotating feeders 27, 28 are driven by gearing within housings 31 and are journalled in plates 29, 30 forming parts of the wall of the housing 13. Telescopic shafts 32 drive the feeders from the power device 21 driving the transfer conveyer 15. Instead of being inclined towards one another as shown the feeders may be parallel.

Title: Improvements in the production of crepe fabrics
Filed: 1943-04-30
Abstract: Fabrics containing highly - twisted crepe threads of cellulose esters of organic acids or cellulose ethers of which at least the last part of the crepe twist has been inserted while the threads are under the influence of a hot aqueous fluid, are subjected to the action of a hot aqueous bath containing a small proportion of a lower aliphatic acid so as to develop crepe effects.  The aqueous bath may contain 1-5 per cent by volume of the acid, and formic, acetic, propionic, or butyric acid may be used.  The fabrics may be treated at 90-99 DEG C.  The highly-twisted crepe threads may be incorporated in the fabrics in various ways.  The weft may be wholly or partially composed of such threads while the warp may be composed of other threads, or warp and weft may be composed of the highly-twisted threads.  A warp of low-twist threads may be formed with a weft containing both right- and left-hand highly-twisted threads. Cellulose acetate crepe threads may be associated with threads of natural silk, or regenerated cellulose.

Abstract: Wood wool/cement blocks contain 1-30 parts by weight dry butadiene copolymer latex solids per 100 parts dry cement.  The copolymer may be formed from butadiene and, for example, styrene, methyl methacrylate, or acrylonitrile. Copolymer mixtures may be used.  The copolymer may be produced by emulsion polymerization, and to ensure stability against coagaultion in the presence of cement, a non-ionic surfactant may be added to the latex.  In an example, wood wool is saturated with a slurry of 500 parts dry cement, 50 parts of water and 200 parts of a butadiene-styrene copolymer latex containing 46% dry solids and is squeezed to remove excess slurry, of which about 2 parts are retained per part of wood wool.  The wet mix is packed into a mould, removed after 24 hours and allowed to dry for 4 days.  The blocks may be used as roofing, flooring or building blocks.
