Title: Improvements in or relating to the production of starches swelling in cold water
IPC: C08B30/14
Filed: 1932-01-08
Abstract: A process for making finely powdered cold-swelling starch by spray drying comprises atomizing starch milk in warm air containing steam, whilst maintaining the saturation temperature of the air, i.e. the temperature at which evaporation of water from the atomized particles commences, above the gelatinizing or hydrolysing temperature of the starch, so that it is first gelatinized or hydrolysed and then dried. Substances such as hydrochloric acid which accelerate the transformation may be added to the starch or, in the form of vapour, to the air.  The pressure p  and water content of the moist air may be varied or substances may be added to modify its saturation temperature.ALSO:A process for making finely powdered cold-swelling starch by spray drying comprises atomizing starch milk in warm air containing steam, whilst maintaining the saturation temperature of the air, i.e. the temperature at which evaporation of water from the atomized particles commences, above the gelatinizing or hydrolysing temperature of the starch, so that it is first gelatinized or hydrolysed and then dried.

Abstract: 732,541. Shedding in hand looms. RUBASHOW, M. Jan. 8, 1953 [Jan. 8, 1952], No. 587/52. Class 142(2).  The warp engages long and short slots arranged alternately in a heald 7 and is held crossed behind the heald by a shed stick 13. The first shed is formed by raising the heald and the second by lowering the heald and raising the shed stick. The stick 13 may be circular or rectangular ; if rectangular the second shed may be formed by turning the stick on edge. The heald is mounted in slots in side members of the loom and a removable bar is secured across the open ends of the slots in the heald. The body of the loom may be a rectangular frame, the length of which is adjustable, or may be a rectangular board. In a modification the warp is wound on to form a crossover near the rear beam and is seized together near the front beam to bring all the warp threads to a common plane ; one shed is then formed by raising the heald and the other automatically on lowering the heald.

Title: Production of Films.
Inventor: WEINBRENNER ERWIN
IPC: D06N3/00
Filed: 1968-01-04
Abstract: 1,196,071. Films. FARBENFABRIKEN BAYER A.G. 4 Jan., 1968 [5 Jan., 1967], No. 648/68. Heading B5B. Films are produced by applying a soluble adhesive to a support, flocking the adhesivecoated support with fibrous flock, coating the dried flock with a high molecular weight plastics material and dissolving the soluble adhesive away after the plastics material has dried or gelled and then removing the support. The fibrous flock may be short fibres 0À3 to 3 mm. long or powdered fibre of, e.g. wool, cotton, rayon, polyester, polyamide or polyurethane and is applied by known flocking processes, e.g. by electrostatic means. The high molecular weight plastics material may be polyvinyl or polyvinylidene compounds, other polyolefines, polyamides, polyimides, polyurethanes, polyesters or rubber and may be applied or sprayed on to the flocked layer if desired from solution. The high molecular weight compound can also be formed in situ on the flocked layer from low molecular weight constituents, e.g. hydroxylcontaining polyesters, polyester amides and polyethers which yield high molecular weight polyurethanes when reacted with polyisocyanates. After drying, the soluble adhesive is dissolved out with water and a solvent, as a result of which the film can be lifted from the support. Soluble adhesives are natural or synthetic rubber latices, polymeric 2-chlorobutadiene, and copolymers of butadiene and acrylonitrile. Water soluble adhesives such as polyvinyl alcohol, alginates and water-soluble cellulose derivatives are preferably used. The high molecular weight material may contain additives, e.g. catalysts, fillers, parting agents, soluble dyes or insoluble pigments. The support material may be a fabric or paper, e.g. dense cotton fabric. In a modification the support is coated with a surface, e.g. silicone rubber to which the soluble adhesive will not permanently adhere and the support is removed from the dried flocked layer before or after treatment of the dried flock layer with the high molecular weight plastics material. More than one coating of the plastics material may be applied and more flocking material may be applied to the film between coats. The film may be subjected to calendering as an after-treatment. Surface changes can also be brought about with hot water. Other aftertreatment steps include embossing and printing. The films are permeable to air and water vapour but are waterproof. The films produced can be applied to a backing material such as polyurethane foam plastics, cotton, rayon, woven or knitted fabrics and synthetics in a subsequent operation. In certain cases the undried coating of plastics material may be applied to the backing material.

Abstract: 1,165,251. Moulding polycaprolactam. H. GOLLER, and N. CHATELET, [trading as ANKERWERK GEBR. GOLLER]. 5 Jan., 1967, No. 728/67. Heading B5A. Dimensionally correct ports are moulded from polymerized caprolactam by running caprolactam in two streams mixed with a catalyst and co-catalyst respectively through separate conduits into a blending channel, mixing by a rotating blade, passing the mixture into the mould and allowing it to polymerize under pressure and thereby fill the mould. Caprolactam containing a catalyst and caprolactam containing a co-catalyst (activator) are respectively stored in heated vessels 17, 18. Liquid is run from each vessel through heated metering valves 21, 22 and pipes 15, 16 into the blending channel 4. The two streams are mixed by blade 6 which rotates, either by rotation of piston 5 through motor 7 and gear 8 or by being mounted on a shaft running through hollow pistons 5 (Fig. 2, not shown). The polymerizing mixture runs into mould 3 formed by mould halves 1 and 2 and pressure is then applied to the polymer by means of piston 5, actuated by the admission of fluid through pipe 12 into cavity 14 behind piston 9. To produce an article of the same shape as the mould this pressure is increased as the polymer sets, to force in more polymer as the polymer in the mould shrinks. In alternative embodiments the co-catalyst may be added after the mixing step, the mixing may be carried out with nozzles instead of a blade and the moulds may be equipped with air vents.

Washing processes; scrubbers; materials for purifying; purifier waste, revivefying. - Cokeoven &c. gases are freed from sulphuretted hydrogen and hydrocyanic acid by an alkaline absorbent liquid such as sodium carbonate solution which circulates between a scrubber and a revivefier such as described in Specifications 170,572 and 190,116, the purifying operation being effected in two stages in the first of which the bulk of the impurities are removed in the first scrubber by a comparatively large volume of solution and the remainder is removed in a second scrubber by a comparatively small volume of solution. Gas enters a scrubber A at 50 and passes out at 51 and thence by a pipe J to the second scrubber I. Solution is sprayed by sprays 3 upon the (coke) filling of the scrubber A and is revivefied by treatment with air in a revivefier D of similar kind, air entering at 52 and escaping by a pipe E passing centrally through the scrubber A. The revivefied solution passes to a sump B from which it is drawn off by a pipe 1 and returned by pumps C to feed the jets 3. A portion of the revivefied solution from the pipe 1 is diverted to a second revivefier F which receives air at 53 and discharges it at G, the further purified solution collecting in a sump H. A float W in the sump H operates a switch. when the level rises sufficiently to close the electric circuit controlling the operation of a pump K, which then draws the solution by pipes 8, 9 and delivers it by jets 10 to the scrubber I which is filled with material having greater surface, such as wood shaving. The solution from the scrubber I returns to the sump B by a pipe 11.

Abstract: 178,190. Calverley, J. E., and Highfield, W. E. Jan. 8, 1921, Phase, changing.-In apparatus for changing the number of phases of a polyphase system, in which a large number of transformer cores is provided, some of which carry windings of more than one of the phases of the system having the smaller number of phases, the magnetic conditions in the various cores are balanced by providing on some or all of the cores supplementary coils connected in one or more closed circuits. In the arrangement shown, for converting from three to 36 phases, eighteen cores 1 - - 18 are provided on six polyphase transformers. Each phase of the three-phase system is wound on one core of the transformer 1, 7, 13 and on two cores of each of the other transformers, the connections for the phase A being shown in Fig. 1. Each core carries a pair of oppositely-connected secondary windings, the phase relations of the 36 secondary windings 1 - - 18, 1<A> - - 18A being shown in Fig. 2. The supplementary balancing coils are connected in three closed circuits x, y, z, Fig. 4, which are interconnected electrically and magnetically to form a symmetrical system. Each balance circuit comprises a. winding on a core of the transformer 1, 7, 13, and windings on four other transformers, the arrangement being such that the vector polygon representing the electromotive forces generated in the circuit under balanced conditions is of elongated form, having a long side corresponding to the winding on the transformer 1, 7, 13. Since this transformer has only one winding in each primary phase, the balance circuits are placed in direct relation with the primary phases, the windings on the transformer 1, 7, 13 being the principal factors in determining the phase and magnitudes of the electromotive forces in the balance circuit. The secondary windings may be connected in a closed ring connected to commutating gear as described in Specifications 140,853, 150,824, and 150,825.
