Title: Improvements in or relating to the sizing of glass fibres
IPC: C08L67/06
Filed: 1960-03-24
Abstract: Glass fibres are sized by coating them with an aqueous solution of the product obtained by reacting an unsaturated polyester resin in an intermediate stage of polymeric growth with an imidazoline compound formed by the reaction of an alkylene polyamine with an aliphatic mono- or di-carboxylic acid.  The unsaturated polyester resin may be formed by the reaction of an unsaturated dicarboxylic acid or its anhydride, e.g. maleic and fumaric acids and their anhydrides, with a dihydric alcohol, e.g. ethylene glycol, triethylene glycol, diethylene glycol, propylene glycol, dipropylene glycol and butylene glycol.  It may also be formed by reacting butene diol with succinic anhydride, the imidazoline compound may be prepared by the reaction of ethylene diamine or diethylene triamine with an aliphatic mono- or di-carboxylic acid having a chain of 3-24 carbon atoms, e.g. oleic, palmitic, adipic, stearic and octanoic acids.  The polyester and imidazoline derivative may be reacted together in the ratio of one mole of imidazoline per mole of dicarboxylic acid in the polymer or per unsaturated group in the polyester.  The size composition may also contain a glass fibre lubricant, e.g. pelargonic amide solubilised with acetic acid, tetraethylene pentamine-stearic acid condensate solubilised with acetic acid or hydrogenated vegetable oils, esters formed from polyhydric alcohols and fatty acids, e.g. the reaction products of ethylene glycol, diethylene glycol, propylene glycol or polyethylene glycol with stearic, palmitic or oleic acid, a particulate material, e.g. cellulose pulp or dispersions of polytetra fluoroethylene, polyethylene, polyvinyl acetate or polyvinylidene chloride, organo-silicon compounds having hydrolysable groups and in which the organic radical is unsaturated or amino propyl triethoxysilane and vinyltrichlorasilane, Werner complex compounds in which a nuclear chromium atom is co-ordinated with a carboxylic group having an aliphatic chain of up to 8 carbon atoms, saturated polyester, polyvinylpyrrolidane, epoxy, polyamide or polyacrylate resins, polyethylene waxes, gelatin, casein, starch and glycerol.  The glass fibres may be formed into strands, slivers or yarns after attenuation and then sized. Specifications 748,391, 755,957, 763,020, 789,240 and 848,271 are referred to.
Patent GB-906762-A (GB)
Title: Improved injection moulding machine
Inventor: GROVES WALTER ROBERT
IPC: B29C45/77
Filed: 1960-03-24
Abstract: 906,762. Injection moulding machines. BRITISH INDUSTRIAL PLASTICS Ltd. March 13, 1961 [March 24, 1960], No. 10541/60. Class 87(2). The pressure on a ram 6 of an injection moulding machine is controlled during the injection stroke so that the full injection pressure is reduced, after the mould 5 has been substantially filled by use of a control rod 30 which is coupled to the ram 6 and moves with it when the pressure on the ram has reached a predetermined pressure e.g. 0À2 of the full injection pressure, the control rod being used to bring about the reduction of the full injection pressure after a predetermined movement with the ram. In the machine shown cold moulding material is fed from a hopper 3 into a heated cylinder 1 and thence into the mould 5 by movement of a piston 4. The piston is coupled to the ram 6, the ram being moved by supply of fluid under pressure into either of the spaces 19, 20 through a main control valve 16, the fluid expelled by movement of the ram escaping through a line 21. The fluid under pressure is normally fed to the valve 16 from a pump 17 through a by-pass valve 13, 18 being a pressure reducing valve. As the piston 4 starts to fill the mould the pressure in the space 19 rises rapidly and this actuates a pre-set pressure sensitive switch 23 which opens an electrically operated valve 25 allowing compressed air to act on a piston 28 in a cylinder 27. Movement of the piston 28 clamps the rod 30 and causes it to move with the ram 6. After a predetermined movement a cam 35 on the rod 30 closes a micro-switch 36 the position of which is adjustable, and this opens an electrically operated valve 38 allowing compressed air to close the by-pass valve 13, so that the pressure applied to the ram 6 is reduced by the pressure reducing valve 18. On completion of the injection stroke the pressure in the space 19 is released and this unclamps the rod 30, which returns to its rest position against a stop 34 under the action of a spring 32. The microswitch 36 is thus opened so that the by-pass valve 13 is again opened. The air operated clamping device 29 may be replaced by an electromagnetic clamping device actuated by the switch 23 and acting directly or indirectly on the rod 30.

Abstract: 601,960. Automatic electric power control systems. WATFORD ELECTRIC & MANUFACTURING CO., Ltd., COATES, H., and VUILLE, B. A. July 5, 1944, No. 10812. Addition to 545,150. Drawings to Specification. [Class 38 (iv)] [Also in Groups XXXVI and XXXVIII] Apparatus according to the parent Specification for controlling an electric power load by restricting it to a predetermined value when circumstances, as detected by a device integrating the energy consumed up to each instant in a series of metering periods, are such that the permitted maximum demand may be exceeded, is combined with an over-riding control apparatus which operates, independently of the firstmentioned apparatus, should the energy consumed up to any instant of a metering period exceed a predetermined value, to restrict the load to a " residual value, i.e. a load less than the " instantaneous minimum load," the minimum load for effective operation of the plant supplied. The additional apparatus minimises the risk of exceeding the permissible maximum demand. Auxiliary plant may constitute the " residual load." Arrangements are described in which the predetermined value at which the over-riding control apparatus operates is : (a) equal to the permissible maximum demand and constant throughout the metering period (Provisional Specification) ; (b) less than the maximum demand at the beginning of the metering period increasing in one or more steps to equal the maximum demand at the end of the metering period. Timing of the steps is discussed ; (c) less than the maximum demand at the beginning of the metering period increasing continuously to equal the maximum demand at the end of the metering-period at a rate corresponding to any value of load between residual load and instantaneous minimum load. In this case if, after restriction of the load by the over-riding control apparatus, the energy consumed at any instant has a value which is a small predetermined fixed amount less than the predetermined value at which the over-riding control apparatus would operate at that instant, load restriction is removed until the over-riding control apparatus again operates. Changes of load may be effected in steps over a short period ; (d) a predetermined fixed amount below the value at which the over-riding control operates at (c) above. In this case, simultaneously with restriction of the load in steps, the value at which the restriction would be removed is raised continuously from the value at which the load was restricted, towards the value at which restriction occurs at (c) above. The Provisional Specification refers to rendering the over-riding control apparatus ineffective towards the end of each metering period. Specifications 501,917 and 579,990 are referred to.
