Patent GB-869163-A (GB)
Title: Co-cured rubber and reinforced resin
IPC: B32B27/00
Filed: 1958-12-16
Abstract: In unitary compositions of rubbery material co-cured with a fibre-reinforced resin, the rubber is a copolymer of butadiene and acrylonitrile, a copolymer of butadiene and styrene, neoprene or natural rubber, and the fibre-reinforced resin is a polymer of a conjugated diolefine of 4-6 carbon atoms per molecule or a polyester. The preferred rubbery material is a copolymer of 75%-45% of butadiene and 25%-55% of acrylonitrile, which may be blended with polyvinyl chloride.  The fibres are exemplified by glass fibre, asbestos, mica, cotton, linen, rayon, silk, hair, nylon, "Orlon" (Registered Trade Mark) and iron, aluminium and copper fibres.  Glass fibres used may have been pretreated with an unsaturated organic halo silane.  The resin reinforcing the fibre is exemplified by "polymeric oils," which are resinous rather than rubbery in character, prepared from butadiene, isoprene dimethyl butadiene, piperylene and methyl pentadiene, or from such diolefines with minor amounts of unsaturated monomers such as styrene, acrylonitrile, methyl vinyl ketone or an alkyl styrene, the preferred "polymeric oil" being obtained by reacting 75-100 parts of butadiene and 25-0 parts of styrene in the presence of metallic sodium as catalyst.  In preparing the unitary compositions, the rubbery material and the polymer of a conjugated diolefine or the polyester may be co-cured at 250 DEG -300 DEG C. in the presence of dicumyl peroxide.  Example 1 is concerned with blending a butadiene-acrylonitrile copolymer with powdered polyvinyl chloride and compounding the mixture with diphenylamine condensed with an aldehyde together with lead phosphite, as stabilizer, carbon black as filler, zinc oxide and stearic acid, as accelerator, a saturated polyester as softener and dicumyl peroxide as catalyst, calendering the compounded rubber to 10 mil and cutting into 4-in.-wide tapes, overlapping the tapes round a steel mandrel, applying glass fibres coated with the sodium copolymer of 80% butadiene and 20% styrene, vinyl toluene and dicumyl peroxide, overlapping more of the rubber tape on the glass fibre reinforced layer, and heating in air at 290 DEG F. for 1 hour to form a rigid pipe.  U.S.A.  Specifications 1,973,000, 2,714,414, 2,747,626 and 2,762,851 are referred to.

Title: Improvements relating to pattern recognition devices.
Inventor: METZER KURT
IPC: G06V10/28
Filed: 1965-09-25
Abstract: 1,163,591. Pattern recognition. ELECTRIC & MUSICAL INDUSTRIES Ltd. 22 Sept., 1966 [25 Sept., 1965], No. 40901/65. Heading G4R. A pattern recognition device subjects patterns to at least one particular test, the responses to the test being divided according to their values into more than two groups, a group which includes more than a given fraction of the total number of responses being assigned a first signal and the remaining groups being assigned a second signal, one of the signals being recorded as the response of patterns to the test instead of the actual responses. The responses of patterns to a test are applied in analogue or binary digital form at 1, the number of responses being counted at 14. Each response also produces a pulse on one of four lines from a level selector 3, to be counted in a respective counter 4, 5, 6, 7. Each counter 4, 5, 6, 7 causes a corresponding bit in a store 20 to be set to 1 if the counter reading exceeds half the total count from 14, and to be set to 0 otherwise. When all the responses have been applied, the store 20 contents are gated, 21, to enable one of AND gates 8, 9, 10, 11. The responses are applied again, and pulses from that one of the level selector 3 outputs corresponding to the enabled AND gate 8, 9, 10, 11 are passed to a store in the recognition device to be used in place of the original responses. This replacement may be preceded by a test that any reduction in recognition effectiveness is acceptable. The fraction "half" mentioned may be replaced by some other smaller fraction.

Title: Improvements in disc brakes
Inventor: BUTLER HENRY JAMES
IPC: F16D55/228
Filed: 1960-11-29
Abstract: 996,386. Disc brakes. DUNLOP RUBBER CO. Ltd. Nov. 17, 1961 [Nov. 29, 1960], No. 40904/60. Heading F2E. In a disc brake comprising a pair of limbs situated one on each side of the brake disc, a brake applying means is formed in each limb comprising a blind cylinder and a piston fluid tightly slidable therein and the axes of the cylinders are inclined relative to the braking surface of the disc, the open ends of the cylinders being so formed that the projected periphery of each cylinder along its axis is clear of the limb on the opposite side of the disc. In the embodiment shown in Fig. 5 each piston 24 acts upon a thrust member 27 of a friction pad 28 and since the cylinder 20 is angled to the plane of the disc the pad 28 moves axially of the cylinder and the pad is guided by the walls of the cylinder and by a brake torque member 29 bolted to the limbs 3 at two spaced locations. A layer 28a of electrically inert friction material of low coefficient friction is bonded to one side of the pad so that there will be no undue restriction on the movement of the pad towards the brake disc. Due to the angle at which the pads meet the disc a self-servo effect is obtained. The friction pad assemblies may be replaced by removing the torque members 29. Fig. 1 shows an alternative embodiment in which the friction pads 9 are mounted on pressure members 8 pivoted at 14 to the caliper housing 2 having two limbs 3 set at an angle of 60 degrees which is bisected by plane of the disc 1. The brake may be applied by piston and cylinder devices 6, 5 or by mechanical actuation of lever 11 which acts through rod 10 to move the pressure members 8 toward each other. The pressure members may be removed to assist in the replacement of the friction pads 9 by withdrawal of pivot members 14 which are screwed into the wob 4 of the caliper housing 2. Reference has been directed by the Comptroller to Specification 767,099.

Abstract: 1,058,716. Slide projectors. C. BRAUN and W. BRAUN. Oct. 18, 1963 [Oct. 24, 1962; March 14, 1963], No.41322/63. Heading G2J. The magazine of a slide projector is driven by an electric motor 2 through a transmission system comprising first and second gears 27, 27' driven in opposite senses by the motor and means for selectively making a drive connection with one or other of these gears to give a forward or reverse motion to the magazine. A lever 15 pivots about shaft 16 under the action of electromagnets 26, or 26' so that pinion 13 mounted on the lever selectively engages constantly driven gears 27, 27'. Crank disc 8 meshes with pinion 13 and is driven in the selected direction to operate the slide charging mechanism comprising connecting rod 6, coupling members 4, 5, and slide mover 3 as described in Specification 1, 058, 715. As disc 8 rotates striker member 9 turns pinion 10 mounted on spindle 11 by one tooth and so advances the slide magazine by one slide width through a rack and pinion connected (not shown). A plate 22 acts on lever 15 by means of projection 23 and spring 14, and the electromagnets move levers 19 or 20 through rods 25, 25', the levers each being connected to plate 22 through spring 24. For forward or reverse drive, the lever 19 moves clockwise or anti-clockwise about pivot 39 and is locked in either displaced position by projection 33 on pivoted lever 34 so that pinion 13 is held against the selected gear. Lever 19 is released when rod 6 on its return stroke depresses end 34' at lever 34 as in Fig. 1. Pinion 15 then returns to its neutral, disengaged position as shown. The magazine may then be moved manually by rotation of knob 37 on spindle 11. The gear teeth are preferably of moulded plastics material. The continually running motor 2 drives a cooling fan. In a modification, lever 15 is moved about its pivot 16 by direct action of the electromagnets, levers 19, 20 being dispensed with.
