Abstract: 1,194,534. Injection moulding. DUNLOP CO. Ltd. 12 July, 1967 [14 July, 1966], No. 31656/66. Heading B5A. A length of material, e.g. a corrugated rubber edging strip 11 for a conveyer belt, is injection moulded in a plurality of stages by a method comprising filling a plurality of moulds 10 in turn at an injection station so that the moulding material extends between and interconnects the moulds, the moulds being individually removed after passing through a curing zone and reapplied in position at the injection station. First embodiment (Fig. 1).-A strip of unvulcanized rubber from a reel 7 is supplied to an injection cylinder containing a feed screw (not shown) which injects the material through a head 5 into the last of a series of hinged-lid moulds 10 having interconnected cavities. As shown the last two moulds are held in a press 17 closed by oil-pressure cylinders 18. The remaining moulds are held in a curing press 19 closed by cylinders 20. The apparatus is also provided with a mould opening device (not shown), mould lowering table (24), mould cleaning station (26), return conveyer (25), mould closing station (27) and piston and cylinder assemblies (23) and (22) for mould removal and return respectively (see Fig. 2, not shown). The moulds are moved forward one at a time when the injection cylinder is moved by cylinders 16 into injection position. Second embodiment (Fig. 6).-In this case the moulds 1-4 move in a circular path instead of a straight line. An hydraulic ram 29 is operable to move a screw type injector 30 and a bolster 31 towards and away from the ends of three of the four moulds. The moulded strip 34 is guided by a pulley 37 on to a take-up drum 38. Curing is effected in a press (28), Fig. 5 (not shown) which also contains a bolster 35, Fig. 6, for restraining the moulds when under injection pressure. A mechanically operated mould indexing lever 36 is also provided.

Title: Manufacture of preparations of starch-degrading enzymes
IPC: C12N9/96
Filed: 1932-11-14
Abstract: A starch-degrading enzyme preparation especially for desizing is made by adding a salt of an acid of phosphorus other than an orthophosphate to the enzyme or its solution.  A small proportion of added salt is sufficient, and increases the activity of the enzyme; for instance ,01-,001 per cent of a pyrophosphate may be added to an amylase solution.  Suitable salts include salts of pyrophosphoric acid esters, salts of esterphosphoric acids such as sugarphosphoric acid salts, salts of inositehexaphosphoric acid, salts of alkyl and aryl phosphoric acids, and metaphosphates.  The compounds employed probably correspond to the formula <FORM:0399998/IV/1> wherein X is a metal atom or ammonium radicle, Y and Z together represent oxygen, or Y may be OR where R is hydrogen, alkyl, aryl, substituted or not, hydroxyalkyl, or a metal atom, and Z may be O.R1 where R1 is alkyl, aryl, substituted or not, hydroxyalkyl, or the group <FORM:0399998/IV/2> The hydrogen-ion concentration may be adjusted to the optimum in the known manner, and if desired activators such as sodium chloride, stabilizers, buffer substances, and other usual additions may be made.  Suitable enzymes are amylases of animal or vegetable origin and amylases formed from fungi or bacteria. Examples describe the following desizing preparations: (1) pancreas amylase and sodium pyrophosphate; (2) pancreatin, sodium chloride and trisodium pyrophosphate; (3) bacteria amylase solution and trisodium pyrophosphate; (4) pancreas amylase and hexose diphosphate and sodium chloride; (5) pancreas amylase, sodium metaphosphate and sodium chloride; (6) pancreas amylase, the acid calcium magnesium salt of inosite hexaphosphoric acid and sodium chloride; (7) bacteria amylase solution and sodium glycerophosphate, the pH value being adjusted to 6,5; (8) sodium glycerophosphate with the materials used in example (4); (9) pancreatin, trisodium pyrophosphate, sodium chloride and calcium formate; (10) pancreatin, trisodium pyrophosphate, acid calcium-magnesium salt of inosite hexaphosphoric acid, and ammonium chloride. p

Water, or other liquid, to be distilled is passed through tubes 17 and 19 and through the tubes 25 of heat-exchanger 22 wherein the water is heated by heating-medium flowing through casing 23; the hot water then flows through pipe 30 into tank 10 where a body 33 of the hot water is subjected to sonic vibrations by piston 46 which is connected by elastic stem 45 to the housing of a vibrationgenerator 42 of the type wherein a roter 55 (Fig. 2) is driven, by pressurized air introduced through nozzle 57, in an orbit within a cylindrical bearing 54. The pressurized air is controlled to cause the rotor to follow its orbital path at a frequency corresponding to the resonant frequency of the liquid-loaded resonator. Vapour bubbles are rapidly evolved from the body of hot water, the vapour condenses on the outside surface of tube 17, and the condensate collects in tray 38. Residual brine flows out of tank 10 through pipe 34. Piston 46, which fits closely within annular wall 48, is supported on an inflated tube 52 of rubber-like material. The piston is faced at the top with a rubberlike material made of polyurethane or silicone. Heat-exchanger 22 is also equipped with a resonator 44a, of the type described, the piston 46a radiating sound waves upwards into the heating-liquid of the heat-exchanger. An orbital-mass generator 80 is mounted on condenser tube 17, whereby droplets of condensate are quickly thrown off, and drop into tray 38. The top 13 of tank 10 possesses elasticity and, when actuated by sonic wave generator 70, causes the downward movement of sound waves into the vapour space of the tank, thereby effecting condensation and agglomeration of minute particles of condensate. Orbitalmass oscillators driven by an electric-motor are referred to.
