Title: Improvements in and relating to rubber compositions
IPC: C08L7/00
Filed: 1927-05-14
Abstract: 272,187. Rubber Latex Research Corporation, (Assignees of Wescott, W. B.). June 1, 1926, [Convention date]. Compositions containing indiarubber and fibres. -Fibres are impregnated with rubber latex, .dried or treated with a coagulant, and milled into rubber compositions, the final composition consisting of at least 50 per cent of rubber. The treatment enables the fibres to be incorporated with a minimum of milling, so that compositions can be obtained containing long fibres, for example, of a length of “-# inch. Suitable fibrous material is tyre or belt scrap, cotton batting, cotton, ramie, animal, or mineral fibres. After impregnation, the fibre is dried, preferably in a vacuum at 150-210‹ F. The amount of rubber deposited on the fibre may vary, but 15-30 per cent is usual. In milling, by passing the composition continuously through the rolls in the same direction, the fibres are drawn into the direction of rolling, so that sheets &c. may be obtained having different degrees of extensibility, flexibility, &c. in different directions. The compositions are applicable to the manufacture of shoe soles, belting, hose, rolls, &c. Specification 273,991 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) states that the fibres mav be treated with rubber solution instead of latex. This subject-matter does not appear in the Specification as accepted.

Abstract: 769,145. Retarder track brakes. GENERAL RAILWAY SIGNAL CO. May 6,1955 [May 6, 1954], No. 13216/55. Class 103 (1). In a railway track retarder the brake beams B carrying wheel gripping shoes S<SP>1</SP>, S<SP>2</SP> are moved towards the track TR by levers L<SP>1</SP>, L2, as a result of rotation of cams CM carried on a common operating shaft 39, 40 parallel with the track. According to the angular position of the cam, the magnitude of the braking effort is adjusted accordingly, the cams having a profile part in the form of an Archimedel spiral and a further part giving a rapid transition from high to low points which is not used for control purposes. The cams are driven through appropriate reduction gearing by an electric motor unit OM having a circuit controller CC, as shown in Fig. 7. The controller CC comprises a series of cams C<SP>1</SP>, C<SP>2</SP>, C3, C 4  adapted to operate through pushers 50 and insulated rollers 51 contacts which become operative in the motor control circuit to determine the movement applied to the cams CM according to the position of a retardation selector lever L, as shown in Fig. 11. One end of the circuit controller CC has a combination pointer and operating lever 57, Fig. 10, indicating, by reference to a scale, the degree of retardation, the controller shaft being adjustable, to allow for wear of the brake shoes, relative to its drum shaft 35 by loosening bolts 54 and 55, Fig. 8, as necessary.

Abstract: 569,944. Aircraft undercarriages. AUTOMOTIVE PRODUCTS CO., Ltd., and BROCK, D. T. Aug. 16, 1943, No. 13307. [Class 4] An undercarriage is provided with a hollow axle to form a reservoir for compressed gas which, in an emergency, may be used to operate a motor actuating the brakes, or to lower the undercarriage in the case of a retractable undercarriage. In the construction shown, the ends of the hollow axle 20 are fitted with sealing plugs 44, 45, the former being provided with a control valve 52 and the latter with a charging valve 49. The valve 52 is normally retained in the closed position by the pressure of the compressed gas, but can be lifted from its seating by a lever 54 which engages the valve stem 53, the lever 54 being operated by the pilot through a Bowden cable 57. Opening of the valve results in the compressed gas passing through a passage 36c communicating by a pipe 36b to a change-over valve 35a on the motor, to operate the latter. The compressed gas may be led to the undercarriage jack, or to a chamber separate therefrom, to lower the undercarriage as described in Specification 508,231. The undercarriage legs may be provided with shock-absorbers 14, 15.

Abstract: 586,794. Reinforced concrete. STEVENS, A. H. (Lock Joint Pipe Co.). July 18, 1944, No. 13742. [Class 20 (iv)] [Also in Groups XXII and XXVIII] In a reinforced concrete pipe or other body, a helically wound wire 18 is secured to an anchor member such as a collar 20 or the steel core 19 by securing a sleeve 16 on the wire such as by swaging, and securing the sleeve to the anchor member by welding, brazing &c. The sleeve may have a lining of abrasive material for improving the joint between wire and sleeve. In apparatus for winding the wire on the core 19 the wire is supplied from a drum 24, Fig. 5, through a guide 28 on a carriage 29. A sleeve 26 is applied to the wire some distance from its end which is temporarily secured at 30 to the core and the wire is wound without tension by rotating the core, and a sleeve 36, Fig. 9, secured to the wire, is welded to the collar 37. A loop in the wire is passed over a pulley 35 mounted on a trolley 39 movable on a beam 40 secured to the carriage 29. The trolley 39 is connected by a cable 38 passing over pulleys 45, 46, 47, to a winch 44 driven by a motor 43. The motor and winch are carried by a pivoted beam 42 which is weighted to give the requisite tension to the wire. The carriage returns to the end 30 of the core, winding the wire under tension, . the motor being controlled by the tilting of the beam 42 so as to maintain an even tension. The sleeve 26 is then welded to the collar 27, the spare length of wire and temporary fastening 30 being removed. In a pipe provided with a saddle piece 52, Fig. 17, for securing a branch connection at 53 a number of pairs of sleeves 57, 58 are arranged on adjacent turns of the wire, the lengths of wire between the sleeves being removed after the sleeves are secured to the saddle by welding.

An iontophoresis apparatus to be held in the hand comprises a casing 12 with a chamber inside for retaining a fluid electrolyte, there being an opening in the casing in which is disposed a freely rotatable ball electrode 32 protruding out of the casing and in communication with the chamber to receive electrolyte therefrom. The electrolyte is contained in a cartridge 36 with a tapered front end closed by an electrically conductive porous septum 42. The cartridge 36 is held replaceably in the chamber against a gasket 40 by the ball-carrying head-piece 30 which screws on to the casing at 24. A slip-on cap, retained by a raised ridge 22, protects the ball when not in use. An insulating wall 34 divides the electrolyte chamber from a rear space which houses a self-contained electrical power-unit 46 with prongs 16 for connecting to a power supply. A cap 20 covers the prongs 16 when not in use. The power unit carries a spring which contacts a pin 62 contacting the electrolyte directly and also, by way of a wire 64, the septum 42 in event of the level of electrolyte diminishing in the cartridge 36. The return circuit is through the casing to a lead 50. A double-throw triple-pole switch 44 mounted on the casing 12 provides for (a) supplying power in the " On " position, (b) charging, through a rectifier, a nickel-cadmium battery in the unit 46, (c) switching off. The circuit of the unit 46 (Fig. 2, not shown) provides a pulsating D.C. output with an amplitude of about 13 volts a 1000 cycles per second, and a pulse width of about 680 micro-seconds, but other repetition rates or a non-pulsating direct current may be used.
