Title: Carbohydrate derivatives and processes for making same
IPC: C08B11/02
Filed: 1933-07-17
Abstract: Water soluble alkyl derivatives of carbohydrates are prepared by the addition of alkyl halides to carbohydrates in the presence of caustic alkali, the amount of caustic alkali being at least 0,3 but less than 1 part to 1 part of carbohydrate, in presence of water in proportion at least 0,5 parts to 1 part of carbohydrate, the amount of water being in each case larger than the amount of caustic alkali but smaller than three times the amount of caustic alkali.  There may be present also an amount of alkali carbonate exceeding 1 per cent or even 20 per cent of the amount of alkali cellulose.  The necessary amounts of caustic alkali and water may be added all at once or can be added in portions during the etherification.  The etherification may be carried out in the presence of diluents such as benzene and ether, as well as catalysts such as copper, iron, or their salts.  In an example, 100 parts of cellulose are treated with 30 per cent caustic soda solution, pressed down to 250 parts, shredded and ethylated.  Modifications are described in which sodium carbonate is added to the alkali cellulose; in which benzene is present as diluent; in which the caustic soda is used in different strength; and in which the alkali cellulose is pressed down to various other weights.  In other examples, the alkali cellulose is partially dried before ethylating so as to reduce the water content.  Again, the alkali cellulose may be allowed to absorb water from the air before ethylating.  In further examples, an addition of solid caustic soda is made to the alkali cellulose.  In another example, alkali cellulose is prepared by mixing together cellulose, caustic soda solution, solid caustic soda, and sodium carbonate, and allowing the mixture to absorb moisture from the air.  In any of the examples, the cellulose may be replaced by starch or dextrin. Specification 14339/14, [Class 2 (ii)], is referred to.

Title: Heat-Actuated Regenerative Compressor for Cooling Systems
Inventor: GRANRYD ERIC GUSTAV ULRIK
IPC: F02G1/043
Filed: 1967-05-02
Abstract: 1,196,473. Refrigerating. INSTITUTE OF GAS TECHNOLOGY. 2 May, 1967, No. 20330/67. Heading F4H. [Also in Division F1] The compressor of a refrigeration system is of the heat-actuated regenerative type comprising an oscillating rotary piston or a reciprocating displacer piston 13 movable in a chamber 1 having disposed therein in series a cooler 7, a regenerator 9 and a heater 11. The working fluid which may be carbon dioxide or sulphur dioxide is admitted at constant pressure from an evaporator through an inlet valve 3 when the working fluid in the chamber 1 occupies the cool part 14 of chamber 1 adjacent the cooler 7 and the hot part 17 of the chamber 1 is almost completely occupied by the piston 13. During the power stroke of the piston 13, working fluid in the cool chamber part 14 is transferred at constant volume through the cooler, regenerator and heater to the hot chamber part 17 and the consequent increase in mean temperature causes the pressure to rise and open an outlet valve 5 leading to a condenser. Thus high pressure working fluid is exhausted at constant pressure. The return stroke of the displacer returns the working fluid at constant volume to the cool chamber part 14 to complete the cycle, which is thereafter repeated. The displacer is driven by an electric or pneumatic motor having sufficient power to overcome the various frictional forces. The cooler is preferably in the form of a finned heat exchanger of copper or aluminium; the regenerator in the form of a matrix of stainless steel wire cloth arranged in layers between corrugated wire mesh; and the heater is in the form of a tube heated from within by a gas burner and surrounded by a radiation shield or wire cloth. A lining 2 covers the chamber 1 and is preferably calcium silicate reinforced with asbestos fibres or calcined diatomaceous silica, bonded with asbestos and coated with a high temperature gas impervious material or fused silica glass foamed to a cellular structure.

Title: Improvements in the manufacture of pre-stressed reinforced concrete articles
IPC: B28B7/42
Filed: 1943-12-06
Abstract: In a method in which parallel reinforcing wires placed under tension are arranged in long production lines and the moulds are run along tracks in the lines whilst embracing the wires, the wires are heated, after concrete has been placed in the moulds, by passing electric current through the wires.  Heat is thereby applied to the concrete to assist in the setting and hardening thereof.  By regulating the heating, relative movement between the wires and the concrete being bonded thereto may be minimised.  The current may pass through the wires from end to end, or may be applied to the wires in the middle of a series of moulds.  The current is applied before or during tensioning of the wires.  The moulds may be insulated from the wires. Supplementary heating, e.g. steam pipes arranged immediately below the moulds, may be employed.

Title: Improvements in centrifugal apparatus for separating and collecting dust or other solid particles from air and gases
IPC: B04C7/00
Filed: 1936-07-23
Abstract: 478,715. Centrifugal dust-separators. CHELTNAM, C. H. W., CHELTNAM, C. H., LAKE, W. H., and GENERAL ELECTRIC CO., Ltd. July 23, 1936, No. 20448. [Class 23] Two separators with separate fans are used for separating dust from gases, and means are provided for varying the ratio of the volume of gas which passes through the secondary separator to the volume which enters the primary separator when the volume of gas to be treated varies. The fan 5 is shown at the clean gas outlet 4 of the primary separator 1 and is driven by a variable speed motor 8, while the fan 12 at the clean gas outlet of the secondary separator 2 is driven by a constant speed motor 13. The connections between the separators are similar to the connections described in Specification 458,792. The dustladen gas enters by the duct 3 and the clean gas is passed by the fan 5 from the outlet 4 to the flue 7. The dust with some gas passes through two ducts 9 to the tangential inlet 10 of the secondary separator 2. The dust is collected in the collector 16 and the clean gas is passed by the fan 12 through the duct 14 to the flue 7. A louvred damper is provided in the flue to permit the dust-laden gas to pass direct to the flue when desired. If the volume of gas entering the duct 3 falls below normal, the speed of the fan 5 is reduced by reducing the speed of the motor 8. This reduces the volume of clean gas discharged by the primary separator 1 and increases the fractional volume passed to the secondary separator 2. In a modification, the primary separator has a vertical axis, and its clean gas outlet pipe is provided inside the separator with a damper comprising a number of pivoted vanes. Specifications 439,740 and 439,814 also are referred to.

Title: Improvements in lignin reinforced natural or synthetic rubber
IPC: C08L21/00
Filed: 1952-08-14
Abstract: Lignin or an insoluble metal compound of lignin is incorporated into natural or synthetic rubber by precipitating lignin or its metal compound from an aqueous alkaline solution, partially separating the precipitate from water by filtration, reducing its water content by airdrying, milling the hydrated lignin or metal compound into rubber in any desired proportion up to 100 parts by weight of lignin or combined lignin per 100 parts rubber to yield a lignin-rubber masterbatch, removing the residual moisture from the masterbatch by air-drying in sheet form, and finally compounding the masterbatch with rubber, fillers, vulcanizing ingredients and softeners.  In an example lignin is precipitated from an aqueous ammoniacal solution by adding formic acid, and the precipitate is filtered, washed, and the moisture content reduced to obtain a product comprising 40 grams lignin per 100 grams thereof.  This product is milled into rubber to form a masterbatch containing 50 parts lignin, 100 parts rubber by weight, which is formed into a thin sheet, dried, and compounded with rubber and other ingredients to form a vulcanizing composition comprising in parts by weight, rubber 100, lignin 36, zinc oxide 10, stearic acid 4, mercaptobenzothiazole 1, tetramethyl thiuram disulphide 0.1, and sulphur 3.  The lignin may be precipitated by acids other than formic acid, or a metal compound of lignin may be precipitated by a solution of ferric chloride, lead nitrate, or potassium alum.
