Title: Improvements in or relating to the manufacture of rubber articles
IPC: B29C37/00
Filed: 1933-12-15
Abstract: Rubber articles having a crinkled surface are manufactured by applying a layer of an aqueous dispersion of rubber or the like to a layer or article of unvulcanized masticated rubber and, when the layer of dispersion has dried, applying a rubber solvent to the composite article or layer.  A crinkling of the surface occurs. The article may be subsequently dried and vulcanized.  A suitable dispersion is diluted latex of 20 per cent dry rubber content.  In an example, to manufacture surgeons' gloves, formers are dipped a number of times in a solution of masticated rubber and dried; the gloves are then dipped in 25 per cent latex, dried, and immersed in a solvent such as petrol.  When dry the gloves are vulcanized.

Abstract: 410,895. Reversing-gearing. AUBIN, E., Elmstead, West Wittering, Chichester, and CLAREMONT, A. W., Vernon House, Sicilian Avenue, Bloomsbury, London. (Representatives of ROYCE, Sir F. H.) Dec. 20, 1932, No. 36083. [Class 80 (ii).] In servo-brake operating mechanism for vehicles of the kind comprising a slipping clutch driven from the road wheels for applying the brakes, mechanism for driving the clutch in the same direction irrespective of the direction of rotation of the road wheels comprises in one form, Fig. 2, a shaft a<2> driven from the road wheels through gearing a, a<1> and driving a co-axial sleeve b in the reverse direction through gearing comprising a sun pinion f secured to the shaft, idle pinions f<2> mounted on the fixed casing a' and an annulus wheel f<3> secured to the sleeve b and geared to the pinions f<2>. The shaft a<2> and sleeve b are arranged to drive the drum d<2> which forms part of the servo-clutch through free-wheel devices comprising members e, e<r> on the shaft and sleeve each having inclined recesses for spring-urged rollers e<3>, adapted in one direction of rotation to have wedging engagement with a drum d secured to the drum d<2> which is thus driven in the same direction either by the shaft or sleeve according to the direction of rotation of the shaft a and the road wheels. In one modification, bevel gearing is substituted for the gearing f, f<2>, f<3>. In a further modification, Fig. 3, only the shaft or the sleeve which is driving the clutch member d<2>, rotates. In this case the shaft a<2> carries a sun pinion g<1>, geared to idle pinions g<2> mounted in a cage g<3> secured to the shaft g one end g<4> of which is spigotted into the end of the shaft a<2>. The pinions g<2> gear also with the annulus wheel h secured to the sleeve b. The shaft g and sleeve b drive the drum d<2> through oppositely acting free-wheel devices e<3> as in Fig. 2. Interposed between a flange h<1> on the annulus wheel h and also between a flange on the cage g<3> and a fixed member h<4> are oppositely acting locking devices j, j<1> similar to the free-wheel devices e<3>. The devices j, j<1> permit the wheel h and cage g<3> to rotate in the direction in which the associated shaft g or sleeve b is adapted to drive the drum d<2> but prevent rotation in the other direction.

Abstract: 790,717. Planing. WALDRICH, O., KAPP, B., WALDRICH, C., HENNES, A. BOEHN-, and KAPP, E., [trading as WERKZEUGMA-. SCHINENFABRIK A. W. COBURG.]. Dec. 16, 1955 [Dec. 18, 1954], No. 36222/55. Class 83 (3). A planing machine comprises a mechanism for moving a tool holder 3 at right angles to the work movement to relieve the tool, means for limiting thetool.. holder movement, and at least two relatively rotatable members co-operating with each other to.lock the tool in working position. In operation, a compressed-air piston 9, acting through a rod 11, adjusting nuts 20; a spring 19 and a plate 17, moves the holder 3 downwardly along guides on an angularly adjustable slide 2 until a plate 49 abuts a fixed stop 50. The spring .19 then yields, and the rod 11 continues its movement to depress a non- rotatable nut 23, causing a screw 25 engaging therewith to rotate. Rotation of the screw causes projections 35 on an axially-fast shaft 27 to engage fixed projections 41, thus locking the holder in position. When the movement of the piston 9 is reversed, the holder is unlocked and is moved upwardly until a piston 48 on the holder abuts a fixed stop 43. The latter stop can be adjusted and secured in position by a toothed plunger 46. Play between the holder 3 and the slide 2 is eliminated by a gib 51 adjusted by a screw 53 and a nut 54.

Abstract: 966,142. Container cap locks. SPRA-LOK CORPORATION. Oct. 21, 1960 [Nov. 6, 1959], No. 36232/60. Heading B8T. [Also in Division E2] A container cap locking assembly comprises a split ring 13, Fig. 3, with one or more flanges 31, 33 projecting inwardly and arranged to retain the cap 12 on the container 11, in which the flanges are so resilient that the cap can be pressed axially on to the container to secure the cap to the container until the split is opened up to permit release of the cap and thereafter resume a locking position. The split ring 13 is made of polystyrene and has out-turned lugs 28, 29, Fig. 4, projecting from either side of the split 30. The lower flange 31 of the ring is adapted to fit under and be retained by the shoulder 23 of the valve cup 19 on the container, and the upper flange 33 retains the out-turned bead 25 of the cap 12. The resiliency of the ring 13 permits the snapping into position of the said parts. The flanges have bevels at 34, 35, respectively, to act as guides for easy assembly. Unauthorized opening of the ring 13 is prevented by heat-sealing or tying together the lugs 28, 29 which may be made to interlock as shown in Figs. 6 and 7. The cap 12 may be attached to an over cap 51, as shown in Fig. 9, with an opening 56 which allows access to the lugs 28, 29 which are not interlocked in this embodiment but have bevelled mating surfaces 58. The opening 56 is formed by turning a pair of tangs 57 which straddle the lugs but allow them to be spread to unseat the ring 13, and is covered by a puncturable seal 59. The lug 28 has a slot 60 engaging the tang 57 to prevent relative movement of the cap and ring. When only an outer cap 71 is provided as in Fig. 14 a modified lockring 75, Fig. 15, abutts the inturned rim 73 of the cap and the skirt 22 of the valve cup 19, and is held in place by tangs 86 in the side wall 72 of the cap. The lower ring 83 of the ring 75 may be omitted. The flange which fits beneath the skirt 22 of the valve cup 19 may be eccentric, or relieved adjacent to the split in any one of the embodiments to facilitate removal of the ring.

Abstract: 742,780. Heat insulation. GENERAL ELECTRIC CO. Dec. 30, 1953 [Dec. 30, 1952], No. 36239/53. Class 64(2). In making a vacuum insulated cabinet, the outer casing 1 or 24 is either so lined with heatinsulating material 5, as in Fig. 2, or is so formed, as in Fig. 6, that it encloses a cavity the boundary surface of which is inclined inwardly and downwardly. In the former case, Fig. 2, a liner 2, of similar shape to but larger lateral dimensions than the cavity, is inserted into the latter. The insulating material is compressed either by forcing the liner into the cavity with the aid of a solid or inflatable plug 15 or by forcing the plug several times into the cavity before the liner is inserted. Guide members, such as thin metal strips 13 or two metal sheets arranged cruciform to cover the bottom and sides of the cavity, or a metal shell slit at the corners, are provided on the surface of the insulating material. In the second case, Fig. 6, the insulating material 25 is attached to the liner 2, and may be compressed before insertion into the casing 24, by the inflation of a doublewalled receptacle of similar shape. The insulating material may comprise glass fibres. The edges of the casing and liner are sealed together and the space between evacuated. Specification 715,174 is referred to.

Abstract: 1396108 Producing stage lighting effects SEIMENS AG 3 Aug 1972 [15 Sept 1971] 36252/72 Heading A6M [Also in Divisions F4 and G5] A stage or adverising display lighting effect generator for producing a plurality of discrete light patterns from one or more coherent light sources comprises at least one two-dimensional static or moving diffraction grating arranged in the path of the light beam to split the light into a plurality of diffraction, orders and one or more modulating members to produce light patterns for projection onto a viewing screen. The grating may be of the phase or amplitude type and the modulating member may be a static or moving reflective or refractive element of regular or irregular effect. In the embodiment shown, a coherent light beam from a laser 1 passes through a beam-diverging optical system 2 to a diffraction grating 3 and the emergent light passes through a condenser lens 4 to a modulating member 5 and is then directed by a magnifying lens 6 on to a screen 7 where it can be seen by transmission (8) or reflection (10). In a modification a separate modulating member is employed for each diffraction order. Light sources or filters of different colours may be used to obtain alternate paterns in the various colours employed.

Abstract: 982,119. Amplifying circuits. INTERNATIONAL SYSTEMS CONTROL Ltd. Sept. 23, 1963 [Sept. 24, 1962], No. 36257/62. Heading H3W. An arrangement for measuring the true output from a device, e.g. a thermocouple 2a which is at a remote point comprises a pair of terminals 15a, 16a to which the device is connected by leads 6a, 7a and a second pair of terminals 17a, 18a which are connected to the input of the measuring device, e.g. direct current amplifier 3. There is no direct connection between the two sets of terminals so that the device 2a can be earthed at any suitable point, while terminal 18a is earthed so that amplifier 3 may be of the unbalanced type. The output voltage from device 2a is measured by means of capacitor 12a which is normally connected by means of ganged relay-operated switches 14a, 14a across terminals 15a, 16a, but is momentarily connected across terminals 17a, 18a when a measurement is being made. To prevent error due to A.C. mains hum picked up on leads 6a, 7a there is connected in series with capacitor 12a a resistor 13a whose value is high relative to the impedance of the capacitor at hum frequencies so that hum voltages are developed across the resistor rather than the capacitor. The arrangement also prevents error due to spurious biasing potentials appearing on both leads 6a, 7a. To prevent transfer of spurious potentials over the stray capacities and leakage paths of the switches 14a a second relay operating further pair of switches 19a, 20a, is provided, operating in unison with the first relay; switch 20a earths input terminal 17a except while a measurement is being made, while switch 19a earths the lead 6a during a measurement. The input to the amplifier 3 may comprise a multiplicity of such circuits with switches operated in sequence so as to measure the voltage at the various thermocouples 8a, 8b &c. in turn. A modification is also described in the Specification (Fig. 2, not shown), in which the top contact of switch 20a is omitted so that the terminal 17a is merely disconnected from the amplifier other than when measurement is being made, a third relay being provided operating after the first and second relays to connect terminal 17a to the amplifier for measurement purposes.
