Patent GB-1521278-A (GB)
Title: Mould clamping for injection blow moulding
IPC: B29C45/67
Filed: 1975-10-27
Abstract: 1521278 Injection moulding FARRELL PLASTIC MACHINERY CORP 27 Oct 1975 44077/75 Heading B5A An injection moulding device comprises a lower fixed mould part 46, 48 and an upper movable mould part 50 connected by rods 42 to a plate 44 actuated by a first piston and cylinder device 70. The upper mould part 50 is connected to the piston rod 56 of a second piston and cylinder device 52. In use low pressure fluid from a pump 82 operates the first device 70 to bring the mould to a closed condition, fluid from reservoir 64 being drawn through a normally open valve 66 to the space above the piston 54 of the second device 52 and fluid from below the piston 54 being forced back into the reservoir. Continued working of the pump with the mould closed causes the pressure of the working fluid to rise and close the valve 66 through line 100, thereby cutting off the space above the piston of the second device 52 from the reservoir. At the same time valve 96 is opened to allow the, now highly pressurized, working fluid to enter the space above the piston of the second device 52 and apply a high clamping force to the mould. The injection moulding device may form part of an injectionblow moulding machine.

[Also in Division F2] An hydraulic pressure intensifier comprises a small piston 1 slidable in a cylinder 2 and connected to a large piston 8 slidable in a cylinder 9 so that variable low pressure liquid supplied through a passage 10 acts upon the piston 8 to provide a proportional high pressure liquid to supply e.g. a braking system connected at 3 to the cylinder 2, the cylinders 2, 9 being both vented to atmosphere when the low pressure supply is withdrawn through respectively a valve 4 in the piston 1 opened by a rod 5 and through a bleed hole 17 in the piston 8. A further piston 13 coaxially connected with the pistons 1 and 8 is at all times urged in a direction which tends to lower the pressure in the small cylinder 2 by a continuously maintained low pressure liquid supplied to a pressure chamber 12 through a passage 11. Liquid released from the cylinder 2 by the opening of the valve 4 passes through a passage 6 in the piston 1 into a reservoir 7. Liquid which seeps past the pistons 8, 13 and through the bleed hole 17 is drained to a sump, not shown, of the low pressure supply. A plunger, Fig. 3 not shown, having a valve may be inserted in the vertical bore 21 of the reservoir 7 and is manually reciprocated in order to pump out air contaminated liquid through a normally closed hole in the high pressure system.

Abstract: 1422385 Impregnating paper RESEARCH CORP 26 Sept 1973 45188/73 Heading D1P Paper is rendered resistant to acid deterioration by impregnation with an atmosphere comprising at least 8% by volume of morpholine. The atmosphere preferably contains at least one-third of its volume of morpholine or may consist substantially entirely of morpholine. The amount of morpholine impregnated into the paper may be sufficient to provide a paper pH (as defined in the Specification) of at least 7.6, preferably at least 8.5, from a starting pH of 5 or less. The paper may be contacted with the morpholine by placing it above a dish of liquid morpholine in a closed vessel and then circulating the air in the vessel to vapourise the morpholine, or by evacuating the vessel to provide a greater atmospheric concentration of morpholine. The paper may be in the form of a book, and may comprise 49% sulphite pulp, 24% bleached soda pulp, and 27% hardwood pulp, may be filled with bag clay and sized with alum-rosin. The process improves the fold endurance and tear resistance of the paper during a period of heat-aging at 100C.

The, or each, span of a suspension bridge is formed by suspending longitudinal tension members between supports, surrounding them with concrete to form a load-bearing structure so that the tension members form at least 20 per cent of the cross-sectional area of the structure which takes up the form of a catenary without longitudinal pre-stressing apart from that imparted by its own weight. The tension members 10 are suspended from supports such as a rock-founded trestle 21, Fig. 2, anchored by means of stressed members 6 and 8. Alternative forms of end support for use where the subsoil is poor are shown in Fig. 3 in which the members 10 are connected to tension members 15 anchored in a block 12 and in Fig. 5 in which the support 16 is anchored by its own weight optionally augmented by a gantry 17, the part 18 in which the members 10 are anchored being connected to the support 16 by tension members 19. When the supports have been constructed, two cables 10 are suspended between adjacent supports and are used to carry a walkway from which suspension of the rest of the cables may be carried out. The cables 10 are then anchored to the supports and tightened to achieve the desired sag. Starting at the centre of each span and using shuttering concrete is introduced around the cables so that they form at least 20, preferably 25 per cent of the cross-sectional area of the slab 1 thus produced. Each end support includes a cantilever arm 2 with an upper surface curved to follow the slab 1 has a resilient end portion 9 and the intermediate supports (not shown) include such an arm at each side.
