Title: Extrusion Press with Die-Changing Device
Inventor: LOMAS ERNEST
IPC: B29C48/08

Abstract: 1,188,677. Extruding. LOEWY ROBERTSON ENG. CO. Ltd. 31 Oct., 1968 [1 Nov., 1967], No. 49693/67. Heading B3P. An extrusion press has a die slide 14 supporting a die 34 or die assembly 30 and movable transversely of the extrusion axis by hydraulic piston-cylinder assembly 16 between a position with the die on the extrusion axis and a position adjacent a die-changing mechanism 50 including a carriage 52 and a further hydraulic assembly to displace the die between the slide and the carriage. The press is hydraulic with a platen 10 with guides 22, 24 for the slide. A latch 40 holds the die assembly in the slide and a plate 42 on the slide serves to close the container 44 during die-changing. The die 34 is supported by bolsters 36, 38 and the rear bolster 38 co-operates with the platen 10 to shear the extruded product. Alternatively, the produce is sheared by a shear blade 48. The carriage 52 is moved on tracks 56 by an hydraulic motor. The further hydraulic assembly comprises piston-cylinder assemblies 60, 70. The assembly 60 is mounted on the slide 14 and serves to push a die assembly 30 from the slide on to the carriage. The other assembly 70 is mounted on a bracket 74 at the side of the tracks 56 and serves to push a die assembly from the carriage into the slide. The carriage accommodates at least two die assemblies and is moved into a heating chamber 80 with one die 130 during use of the other die 30. The chamber has an insulated lining and heating elements 84 in the form of gas burners, resistance or induction heaters.

Title: Prepration of sucrose derivatives
IPC: C07H13/08
Filed: 1973-10-26
Abstract: 6,6'-Dichloro-6,6'-dideoxysucrose is prepared by the following reaction steps:   a) reaction of sucrose with methanesulphonyl chloride in N,N-dimethylformamide, b) complete acetylation of the resulting chlorinated sucrose and isolation of the acetylated product containing 6,6'-dichloro-6,6'-dideoxysucrose hexaacetate,   c) purification of the said hexaacetate and   d) deacetylation of the purified hexaacetate.   To suppress the formation of a trichlorinated by-product, it is advantageous to allow the reaction in stage a) to start at a temperature in the range from -40 to -15 DEG C. In order, furthermore, to remove any formate by-products which are present in the product, it is advisable for the acetylated product which has been obtained in stage b) to be deacetylated before the purification stage c) and subsequently acetylated once again. The product prepared according to the invention is used as intermediate for the preparation of sucrose derivatives which are required, for example, for the preparation of resins.

Title: Improvements in or relating to presses particularly injection moulding presses
IPC: B29C45/68
Filed: 1966-11-08
Abstract: 1,128,539. Injection moulding machines; hydraulic presses. WERNER & PFLEIDERER. 8 Nov., 1966 [10 Dec., 1965], No. 49998/66. Headings B5A and B5F. In a press, particularly for injection moulding, and comprising mechanical lifting means 8, 9 for raising one mould half 3 away from the other mould half 2, fluid pressure means 4 is provided for counteracting the weight of the movable mould half 3 during opening of the press. The mechanical lifting means comprises an electric motor 8 and spindle 9, while the fluid pressure means comprises hydraulic cylinders 4. Fluid is initially released from a mould-locking cylinder 12 through a conduit 11. The force applied to the cylinders is sufficient to be just more or less than that required to raise the half 3, so that the lifting mechanism 9 either brakes or assists the vertical movement. At an upper end position a switch (15) operates a control member (16) to stop flow of oil to the cylinders 4 and supply oil either to cylinder 12 or through a conduit (17) leading to an injection cylinder (not shown). During closing of the mould, oil flows from chambers (13) of cylinders 4 through conduits 10 and a regulating valve (18) while the lifting mechanism operates.

Title: Tank Coupling.
Inventor: DENNEY RAYMOND EDWARD
IPC: B61D5/00
Filed: 1966-11-09
Abstract: 1,153,381. Fluid-pressure servomotor systems. AEROQUIP A.G. Nov. 9, 1966, No.50281/66. Heading G3P. A fuel tank filling apparatus which allows the admission of only a predetermined amount of fuel, comprises a float and valve mechanism 20 which controls a fuel supply valve 16 in accordance with the fuel level in the tank. The supply valve 16 consists of a housing 22, which is screwed into a vertical wall 12 of the tank 10, and has formed within it a chamber 40 and channel 24, the latter being connected to a supply line 34 by a nut 32. Located within this chamber in a differential area U-shaped movable piston 60 and a fixed T-shaped member 46, the two being in sliding contact with one another. A duct 140, at one of its ends communicates, through an extension 110, with the larger face 62 of piston 60 and at the other end with a valve 130, a small bleed passage 116, opening into the channel 24, being interposed between these connections. In the closed position, Fig.2 (not shown), face 62 of the piston abuts section 54 of the T-shaped member and so the lateral walls of the piston close ports 106 communicating with the tank. Upon the float attaining the full line position shown and hence valve 130 opening, supply pressure acting on piston face 62 is relieved via the valve 130 and so the supply fluid-pressure acting on the smaller annular face 70 of the piston overcomes the biasing due to a spring 88 and moves the piston to the position shown, thereby allowing fuel to flow into the tank. On reaching a certain predetermined level, the float 118 attains the dotted line position and in doing so closes the valve 130. This prevents fluid entering duct 140, through passage 116, to pass into the tank and so a pressure build-up occurs until the pressures within channel 24 and duct 140 have been equalized. This pressure acts, through the extension 110, on face 62 of the piston and although the pressure acting on the two end faces of the piston is now the same, a (net) force is produced on account of the different end-face areas and so the piston moves to close ports 106. Further addition of fuel may be achieved by manually unseating, through a lever mechanism 102, (100), the valve 80 thereby reducing the pressure acting on the face 62 at which stage, further use of the lever mechanism places the piston in its open position and fuel flow is restarted. On releasing the mechanism, the valve is again closed by the increased pressure acting on face 64.

Abstract: 1,237,465. Heat relax treatment of thermoplastic films. EASTMAN KODAK CO. 25 Oct., 1968 [27 Oct., 1967], No. 50828/68. Heading B5B. In a continuous process for the treatment of stabilized thermoplastic film which has been oriented in the longitudinal and/or transverse directions and thereafter heat set under tensions so that the dimensions of the film are held substantially constant to improve its dimensional stability, the hot oriented heat set film is passed through a heat relax section or zone in which the temperature of the film is maintained above its second order transition temperature and in which the film is maintained under only slight tension. The hot film is then passed through a cooling section or zone in which the temperature of the film is lowered to below its second order transition temperature. The heat relax and the subsequent cooling steps of the process are characterized in that in the last stage or stages of the heat relax section, in its passage from the heat relax section to the cooling section and in the first stage or stages of the cooling section, the travelling film is supported in such a manner that there is no span of unsupported film which is over 30 inches long. The film may be supported on "air bars" (hollow stationary rods or shafts having holes along their length through which jets of air under pressure issue) the holes being located where the film passes over the rods or shafts and the air pressure being sufficiently high to form an air cushion between the film and the rod or shaft. The film may be supported on idler rolls in both the portion of the heat relax section adjacent to the cooling section and in the beginning of the cooling section, the unsupported film spans between the idler rolls being at most 30 inches and the film travelling in a sinuous path over the idler rolls and being reduced to below the second order transition temperature while being passed over the idler rolls in the cooling section. The film may consist of a polyester such as poly(ethylene terephthalate) or poly(cyclohexane - 1,4 - dimethylene terephthalate).
