Title: Incorporating rubber into thermoplastics materials
IPC: C08J3/00
Filed: 1971-07-29
Abstract: 1348286 Incorporating grafted rubbers into thermoplastics material BADISCHE ANILIN- & SODA-FABRIK AG 29 July 1971 [30 July 1970] 35617/71 Heading C3G A process for incorporating rubber into a thermoplastics material comprises precipitating a rubber latex, freeing the rubber mechanically of 10-98% of its initial water content so that the resulting rubber contains 2-50% by weight water, mixing the said rubber with the thermoplastics material at a temperature which is above the softening point of the thermoplastics materials, and removing the remainder of water during or after the incorporation. The thermoplastics material may be a homopolymer or copolymer of styrene, vinyl chloride or methyl methacrylate. Numerous rubbers are specified but it is preferred to use graft copolymers in which monomers forming rigid polymers are polymerized in aqueous emulsion on to a rubber base. The finished plastics material advantageously contains 5-60%, preferably 10-50%, by weight of the rubber worked into 95-40%, preferably 90-50%, by weight of thermoplastics material. The initial water removal may be carried out by filtration, pressing or centrifugation. Incorporation of the rubber into the thermoplastics material may be carried out in conventional mixing equipment, advantageously extruders or kneaders. The thermoplastics may be introduced into the mixing equipment as a melt. Alternatively it is possible to start from a dispersion of the thermoplastics material, to precipitate and partly dehydrate the same, and then to work it into the moist rubber. When an extruder is used it is advantageous to meter in the moist rubber first since this may be carried out under mild conditions without using superatmospheric conditions. After the thermoplastics material and rubber have passed through together the two components are mixed homogeneously together, at a temperature above the softening point of the thermoplastics material. The remaining water is removed by counterpressure or evaporation. In the example a styrene/acrylonitrile (70:30) copolymer is incorporated into a rubber latex produced by emulsion graft polymerization of 50 parts by weight of a mixture of styrene and acrylonitrile (70 : 30) in the presence of 100 parts by weight of a butadiene/butyl acrylate (40 : 60) copolymer.

Abstract: 994,793. Hydraulic apparatus. W. LUCK. Oct. 5, 1961 [Oct. 6, 1960], No. 35936/61. Heading F1P. [Also in Division F2] A pressure transmitting and replenishing device for a hydraulic or pneumatic system, such as the braking system of a vehicle, comprises a housing 1 connected between a transmitter and receiver, at least one piston 8 movable in the housing to transmit pressure from the transmitter to the receiver, at least one replenishing piston 17 movable at a predetermined pressure to establish a direct hydraulic or pneumatic connection between the transmitter and receiver, and means 28 for locking said pistons together when the pressure on the receiver side drops below a predetermined pressure to prevent a flow of fluid from the transmitter to the receiver. The transmitter, such as the master cylinder of a braking system, is connected to a nipple 3 in the housing and the receiver, such as the brake cylinder, is connected to a nipple 2. The piston 8, which is urged by a spring 16 against a shoulder formed by the nipple 3, is hollow and receives the replenishment piston 17 which is urged by a spring 21 is press a ball 20 against a seating 13 in a bore 12 in the end of the piston 8; the tension of the spring 21 is adjustable by a screwed plug 15. In operation, when pressure is applied to the device by operation of the transmitter, the piston 8 is moved to apply the pressure to the receiver. If leakage has occurred in the receiver, the piston 8 moves until the coils of the spring 16 abut and a further increase in pressure lifts ball 20 from the seat 13 against pressure from spring 21 so that fluid can pass through the bore 12, along grooves 18 in piston 17, and a bore 36 in plug 15 to replenish the loss. A further piston 25 is disposed within the piston 17 and has a tapered portion which, in the event of a drop in pressure in the receiver below a predetermined minimum level caused by severe leakage, is urged by a spring 23 to move a ball 28 into a groove 27 in piston 8 to lock pistons 8 and 17 together to prevent lifting of the ball 20 from the seating 19 and a flow of fluid to the receiver. A by-pass passage 31 having a releasable plug 33 is provided to facilitate filling of the system. A device may be incorporated in the lines to each of the brakes of a vehicle or a separate device be used for the front and rear brakes. Several devices may be assembled in a single housing.

Abstract: 624,383. Regenerators. RICARDO, H. R., and ALCOCK, J. F. Dec. 5,1946, No. 35988. [Class 64(i)] Relates to a heat exchanger comprising in combination two or more rotors as described in Specification 608,065. According to the invention, the rotors are mounted coaxially and either concentrically or with their centres spaced apart along the common axis. Furthermore, an outer casing encloses all the rotors and has through passages for the hot and cold gases fed to the rotors. Three annular rotors, A, B, C in toroidal casings D, E, F respectively are equally spaced along a common axis and enclosed in a casing G divided into twin passages by a partition G', about which the rotors turn. The rotor casings are mounted in inclined partitions K, L and the rotors are rotated in their individual casings by means of toothed racks R, each meshing with two simultaneously driven pinions. The drive from a shaft M is transmitted to a shaft N' carrying a gear wheel N<SP>2</SP> meshing with a gear wheel 0 on a shaft 0<SP>1</SP>, carrying gear wheels 0<SP>2</SP> driving the pinions. The pinions are spaced apart along the rack R and each has a part cut away to clear transverse partitions in the rotors. Hot gas entering the casing G through an inlet J passes through the rotors, giving up heat to the matrices, and emerges through an outlet J'. Cold gas entering through an inlet H absorbs heat from the matrices in its flow through the rotors and emerges through an outlet H'. In an alternative construction, the three rotors are arranged concentrically.

In a watch balance regulator, in order that the curbing point A of the balance spring shall lie substantially in a central position between the curb pins or the like of the regulator arm throughout the range of angular adjustment of this arm, and to avoid any necessity for an additional radial adjustment, the balance spring retains its general shape of an Archimedean spiral of the form in polar co-ordinates r = S/2# # over the outer peripheral portion which is engaged by the curb pins, the arm being rotatable round a fixed axis M at the distance r from the point A, which axis in the zero position of the regulator lies on the normal to the spiral at the point A, this normal forming with the radius vector OA (O being the origin of the spiral) an angle α determinable from the expression tan α = S/2#r. The value of # being expression tan α = S/2#r. The value of # being normally about 21# at the point A, it is shown that for this value the length r is approximately equal to the radius of curvature of the spiral at this point, thence the circular concentric movement of the curb pins corresponds closely to the curvature of the spiral.

Abstract: 740,527. Manually-actuated valves. ROTH, R. Dec. 29, 1953 [Dec. 30, 1952], No. 36066/53. Class 135. A valve for controlling the flow of pressure fluid, e.g. compressed or liquefied gas, between a gas container and an inflatable article, comprises a valve body 1, Fig. 1, having connections 2, 3 to the container and the inflatable article respectively and a slidably mounted gastight plunger 6 retained on an annular seat 4 by resilient locking members 11. The members 11 extend from a ring 10 secured to the plunger and wedged between an internally-coned surface 18 of a screw-threaded cap member 17 and a pin 23 through which passes a cable 24. On pulling the cable the pin 23 is withdrawn from between the ends 12 of the locking members 11 which move inwardly allowing the plunger to be unseated by the gas pressure within the container and a spring 15. Clearance between adjacent faces 14, 19 of the valve body and cap member respectively permits of screw actuation to close the valve when the pin 23 and cable 24 are removed. In a modification, balls 39, Fig. 3, seated in a diametral groove 34 in a lengthened plunger 30 replace the locking members 11. The inner face of the cap member 17 is formed with two coned surfaces 40, 41 of differing inclinations. On removal of the pin 23 and cable 24, the gas pressure acting on the plunger 30 urges the balls 39 up the coned surface 41 on to the coned surface 40 to permit opening of the valve. As before, the valve may be operated by screw actuation after removal of the pin 23 and cable 24. Removable pins 37 retain the cap member on the valve body and the pin 23 in its valve closed position.
