Patent GB-874759-A (GB)
Title: Reinforced polyester-fibre laminates and moulding compositions
IPC: B29C70/00
Filed: 1957-07-29
Abstract: <PICT:0874759/IV (a)/1> An unsaturated polyester resin, which is in its thermoplastic state and capable of further curing, is mixed with a filler to form a dough, a fibrous reinforcing material is coated with the filled resin dough, and the resulting coated material cut into pieces to form a moulding composition, the fibres in each individual piece being of substantially the same length.  The unsaturated polyester resin is a mixture of an unsaturated alkyd resin with a copolymerizable monomer, e.g. styrene, diallyl phthalate or triallyl cyanurate, which also may be partially polymerized.  The alkyd may be that obtained from propylene glycol, maleic anhydride and phthalic anhydride or isophthalic acid.  The fibrous reinforcing material is one in which the fibres or filaments are substantially parallel and run in unbroken length through the material.  Glass fibres or filaments are preferred, but rayon and the like may be used.  The reinforcement may be in the form of strands, rovings or yarns.  The filler may be kaolin, chalk, gypsum, lime, asbestos, mica, quartz, wood meal, cork powder, cellulose flakes, metal powder or coal.  The mix may be pigmented or dyed.  Suitable curing catalysts are organic peroxides, e.g. benzoyl peroxide, di-t-butyl peroxide, cumene hydroperoxide, diisopropylbenzene hydroperoxide, and t-butyl hydroperoxide.  The mix may also contain a lubricant, e.g. aluminium stearate or other stearates, silicone oils, lecithin or paraffin and like waxes.  As shown, the unsaturated polyester is mixed with catalyst in the kneading apparatus 1.  Filler, and if desired, lubricants and pigments are added, and the whole mixed to a uniform dough.  This dough is rolled out between the rollers of two pairs 2a and 2b to form two continuous thin layers.  The reinforcing material 3 is drawn between these two layers which are then pressed together between the belt 4 and the roller 5.  The product is cut into pieces by cutters 6 and 7.  Alternatively, greater numbers of layers may be used, the reinforcement may be coated by extruding the resin-filler mix around a fibre roving, or by knife coating.  The pieces may be sprayed with mould releasing agents, such as aluminium stearate or talcum, or with filler to reduce their stickiness.  They may also be further formed between rotating plates or the like into pellets or cylinders.  The reinforcement may be impregnated with unsaturated polyester resin before coating it with the resin mixture. The products can be moulded to complex shapes in a mould under heat and pressure.

Abstract: 395,888. Valves. YOUNG, M. S., Scarsdale, New York, U.S.A. Aug. 31, 1932, No. 24339. [Class 135.] - Locking.-An apparatus for controlling the filling of fluids, e.g. gasoline or lubricating-oil, into a receptacle, e.g. a small or intermediate size storage tank, or a large reservoir of the underground gasoline storage type, is arranged for preventing unauthorized substitution of the fluid by providing a key-shaped filling nozzle which actuates a member normally holding closed a valve situated in the fluid intake of the receptacle. In one form a filling nozzle 6, Fig. 2, has a key portion 9 of the cylinder type co-operating with tumblers 8 carried by a movable semi-circular gate member 7 which, when released by the unlocking action of the key can be rotated about a pivot 21 to the position shown to give access to an aperture in a fixed socket 5 which is held by a projection 13, Fig. 1, and a spring 15 which is compressed to allow the socket 5 to be brought into position and then expands so as to contact the wall of the vessel. A cap 11, Fig. 1, may be used to cover the filling head. The filling nozzle 6 may be a funnel as shown or may be on the end of a flexible filling tube. Fig. 1 shows also a pump 14, a unit measurecontainer 18, and a measuring stick 19. Drip from the discharge device can seep slowly through the valve. Another form adapted for mobile liquids such as gasoline is shown in Fig. 5, in which a butterfly valve 90 is pivoted in a sleeve 92 fixed in a head 82 screwed into the filling tube 80, and is actuated by a cam surface 99 of a rotatable sleeve 93 which is normally held fixed by vertical tumblers 94, contacting at their middles with projections 97 on the fixed sleeve 92. A filling nozzle 84, secured by a cap 89, has an irregular edge forming a key which co-operates with the tumblers 94 and depresses them so that their reduced middles come opposite the projections 97 and permit the sleeve 93 to rotate and actuate the valve 90. A projection 84a on the nozzle 84 ensures that the latter cannot be removed while the valve is open.

Title: Improvements in and relating to machine guns
IPC: F41A19/55
Filed: 1938-05-09
Abstract: 496,200. Hydraulic apparatus. NASH, A. G. FRAZER-. May 9, 1938, No. 24520. Divided out of 493,468. [Class 69 (ii)] [Also in Group XXI] Relates to a double-acting triggeroperating device 3 for machine guns, in which fluid pressure acts positively on a piston 2 in one direction to fire the gun and in the other direction to interrupt fire. According to the invention, the area on the piston exposed to pressure during the firing stroke is less than the area exposed to the pressure acting to interrupt the fire, and part of the smaller area is obturated in the position shown, as for example by a stepped portion 26 of the piston, so that the pressure to cause firing first acts on a small annulus 27 and later on a larger annulus. This construction ensures that leakage round the piston 2 will not cause unintentional firing since there is always excess pressure tending to keep the piston in the non-firing position, and, further, when the firing stroke starts, there is a sudden increase in the force acting on the piston annulus. In the apparatus shown, the piston is controlled by a slidevalve 23 actuated by a remote trigger x. The valve is shown in the non-firing position in which the pressure feed pipe 15 is connected to a pipe 9 leading to a port 5 in the cylinder 3, the port 4 being then connected by a pipe 8 to the exhaust pipe 16. When the valve 23 is moved to the right to cause firing the pressure fluid enters at the port 4 and exhaust takes place through the port 5.

Title: Improvements in or relating to control systems for x-ray tubes

Abstract: 677,145. Supply system for X-ray tubes. PHILIPS ELECTRICAL, Ltd. Sept. 27, 1949 [Sept. 30, 1948], No. 24751/49. Class 38 (iv). In a high-tension supply system for an X-ray tube employing a variable ratio transformer by which the voltage applied to the tube may be controlled, the ratio of the circuit resistance on the mains side of this transformer to the circuit resistance on the tube side of the transformer is made such that the total voltage loss in the circuit is proportional to the input power to the tube and is constant for a constant power input at varying voltage, whereby the voltage loss may be compensated throughout the voltage range by an auxiliary boosting voltage proportional to the load. A formula for determining the required resistance ratio is included in the Specification. Fig. 8 shows a system for supplying either of tubes 17, 18 through a high-tension transformer 12, filament transformer 19 and multipole change-over switch 14-16. The filament transformer is supplied from the mains 8 through a constant voltage device 6 and regulators 3, 4, the last two of which are coupled, respectively, with the voltage selector switch of a tapped autotransformer 7 through which the high-tension transformer is supplied, and the timer 25. By this means the tube current is limited by the settings of the high-tension and time controls and overloading of the tube prevented. A resistor 5 may also be switched into the filament circuit if the two tubes have different characteristics. A resistor 9 in the mains circuit permits adjustment to the required ratio the resistances of the circuits on the two sides of the autotransformer 7. The auxiliary boost voltage for compensating for the supply circuit voltage drop comprises a pre-set component derived from a secondary winding 20 on transformer 7 and a component dependent upon the timer setting. This component is obtained from a tapped reactor 22 energized from transformer 7 and having a wiper 21 ganged with the timer, the voltage appearing between the tapping of the reactor and the wiper being injected into the primary circuit of the hightension transformer by a further transformer 23.
