Abstract: 827,314. Making gilled tubes; welding by fusion. ALCO PRODUCTS Inc. Jan. 31, 1957, No. 3407/57. Classes 83 (2) and 83 (4). In a machine for welding longitudinal fins to a tube, e.g. to form a heat exchanger unit, the fins are seam-welded using gas-shielded arcs and devices are provided to apply pressure to the fins to hold them in contact with the tube adjacent the welding zone. The fins and tube are of corrosion-resisting metal such as stainless steel or non-ferrous metal. The fins 13, Fig. 2, are formed of channel section the web 13b of which is thinned by cold rolling. The tube 10 is supported vertically in a frame 16 and the channels 13 are held in place by slotted plates 270, Fig. 4. Cooling water is passed through the tube. The channels are welded simultaneously by a plurality of inert gas-shielded tungsten electrode torches 33 carried by support blocks 32 on a platform 19, which is mounted on and traversed by an endless chain driven by a motor 23. Rollers 31 resiliently mounted in the blocks 32 press the channels 13 against the tube 10. When the starting button is actuated, water and inert gas are supplied to the torches 33, the welding generators are connected to the torches, the platform 19 is lowered and high-frequency current is connected up to start the welding arcs. At the completion of the welds switches 60 actuated by the platform 19 cut off the welding current, stop the platform and after a delay stop the supply of gas and water. In a modification the torches are stationary and the tube and fins are moved upwardly during welding.

Patent GB-438110-A (GB)
Title: Improvements in and relating to moulded products
IPC: C08J3/20
Filed: 1934-02-07
Abstract: A moulding-composition which when moulded will produce articles having a pearlescent character is prepared by forming a homogeneous mixture of metallic particles and a thermoplastic reaction product of rubber and a halogen acid of tin.  The composition may also contain dyestuffs with or without pigments. The preferred metallic particles are aluminium, copper, bronze magnesium, lead and zinc added in amounts of 0,1 to 1,0 parts per 100 parts of plastic material.  The composition also preferably contains a soap such as castile soap to assist in the even distribution of the metal particles on moulding. The colouring effects are varied to some extent by the particle size of the metallic powder, the particle size of the moulding powder as it is placed in the mould, and the temperature at which the moulding operation is carried out.  A thermoplastic rubber derivative suitable for use in the present invention is prepared by plasticizing raw rubber with benzene to form a cement, and reacting the cement in a steam jacketed mixer with 10 per cent of hydrated chlorostannic acid for approx. 3 hours.  The exact time of reaction is determined by the viscosity desired in the final product; a longer reaction time yielding a harder product.  The reaction product is discharged into its own volume of water preferably containing a little sodium sulphite, and the benzene removed by steam distillation to yield a sand like product which contains chlorine and appears to be a hydrogen chloride addition product.  This material is thermoplastic and metallic particles may be uniformly distributed in it by milling. This product is then ground to form the moulding powder of the invention.  The Specification as open to inspection under Sect. 91 comprises also the incorporation of metallic powder into any thermoplastic material.  Materials mentioned are the reaction product of rubber with hydrochloric acid and the halide of an amphoteric metal, polymerized vinyl compounds, styrol plastic compounds, and cellulose plastics such as cellulose acetate and cellulose nitrate. This subject-matter does not appear in the Specification as accepted, but forms the subject-matter of Specification 440,879.

Title: Improvements in or relating to the detoxification of foodstuffs containing aflatoxin
Inventor: SREENIVASAMURTHY VENKATESIAH
IPC: A23L5/20
Filed: 1967-06-07
Abstract: Food materials containing aflatoxin, such as groundnuts, pulse flours, parboiled rice and other foodstuffs which are infected with Aspergillus flavus including infant and weaning foods and protein isolated from groundnuts, are detoxified by treating an aqueous suspension of the food material with hydrogen peroxide at a pH value of at least 9.5 and a temperature of not less than 70 DEG  C. for a period of not less than 15 minutes.  The resulting mixture after the heating is gradually cooled for a period of at least 30 minutes, its pH value is adjusted to 7.0 and it is then mixed with catalase (crude extract of a Rhizopus culture) to destroy residual hydrogen peroxide. The temperature and pH should not exceed 80 DEG  C. and 10.0, respectively, during the treatment with hydrogen peroxide.  The treatment can take place in two stages interspersed by a readjustment of pH.  The relative proportions of the hydrogen peroxide and the food material are suitably equivalent to 0.03-0.05 part by volume of a hydrogen peroxide solution of 20 volume strength per 1 part by volume of an aqueous suspension of the food material having a concentration of 15%.  The treated suspension may be dried in a spray drier or roller drier.  Examples are directed to the treatment of milky emulsions of groundnut cake flour.  Acknowledgment is made of the detoxification of groundnut cake flour by treating it with chlorine.ALSO:Food materials containing aflatoxin, such as groundnuts, pulse flours, parboiled rice and other foodstuffs which are infected with Aspergillus flavus including infant and weaning foods and protein isolated from groundnuts, are detoxified by treating an aqueous suspension of the food material with hydrogen peroxide at a pH value of at least 9.5 and a temperature of not less than 70 DEG C. for a period of not less than 15 minutes.

Abstract: 649,277. Separation of air. BRITISH OXYGEN CO., Ltd., and ROBERTS, N. W. Feb. 12, 1948, No. 4085. [Class 8(ii)] A process for separating argon from air comprises rectifying the air in a column 1 to produce an argon-oxygen fraction, increasing the pressure of such fraction at a compressor 10 and transferring it to an auxiliary rectification zone 11 wherein it is separated into an argon rich fraction delivered at a valve 16 and a substantially pure oxygen fraction delivered at a valve 15, the temperature gradient in the zone 11 being maintained by indirect condensation of a fluid in a coil 12 and its vaporization at a condenser 13 at such a pressure that the vaporized fluid can act as reflux medium in the primary rectification zone. The fluid consists of nitrogen from the top of the column 1 which is heated to normal temperatures in exchangers 8, 24, 25, compressed at a compressor 26 and one portion expanded to ten atmospheres at an engine 27 and mixed with liquid nitrogen leaving the exchanger 24 and also expanded to ten atmospheres at a valve 28. The mixture is thereafter condensed in the coil 12 and is revaporized in the condenser 13 and afterwards used as reflux in the lower column 2.
