Title: Improvements in or relating to method for gas expanding closed cell cellular rubber
Filed: 1942-08-07
Abstract: To facilitate the penetration of gas under pressure into rubber of considerable thickness or diameter, in the production of closed-cell cellular rubber, bunches of fibres providing gas-passageways to the interior are used, e.g. as spaced threads of cotton yarn, or sliver which has been impregnated with a thermally-operative disintegrating medium, e.g. sulphur chloride applied as a 5 per cent solution in carbon tetrachloride so that when the rubber is vulcanized after gassing, the cotton disintegrates to allow the rubber freely to expand.  Examples disclose cotton yarn wound about the central ply of a three-ply thick rubber sheet; and threads extruded into a rubber cylinder when it is being formed.ALSO:To facilitate the penetration of gas under pressure into rubber of considerable thickness or diameter, in the production of closed-cell cellular rubber, bunches of fibres providing gas-passageways to the interior are used, e.g. as spaced threads of cotton yarn, or sliver which has been impregnated with a thermally-operative disintegrating medium, e.g. sulphur chloride applied as a 5 per cent solution in carbon tetrachloride so that when the rubber is vulcanized after gassing, the cotton disintegrates to allow the rubber freely to expand.

Title: Improvements in change speed gear
IPC: F16H3/66
Filed: 1928-04-14
Abstract: 315,476. Chambers, J. H. April 14, 1928. Variable-speed gearing comprises a primary epicyclic train c, b, d, Fig. 6, enclosed by its driving-member e and a secondary train c<1>, b', d for yielding the lowest forward speed and reversed driving. The floating ring member d is common to the trains, as is the encircling driver e. The primary train alone drives a shaft a<2> at three speeds, during which the secondary train is locked solid by a splined clutch plate p engaging the end of pinion c<1>. Friction clutches c<3>, c<2> on the pinions c, c<1> may take the drive alternatively from the ring e. These clutches c<3>, c<2> are simultaneously operative for the fourth speed or solid drive. For the third speed, clutch c<2> through the solid secondary train drives ring d, and sun gear c is held fast by a pawl engaging plate s<4>. The planet carrier b<1> of the primary train is the driven element and is separate from the carrier a<11> of the other train. For the second speed, the sun c is driven through clutch 0' and ring d is held fast through the locked secondary train and plate s<5> and a pawl. For the first speed and reverse, the clutch plate p is slid into engagement with the casing at f<1>, so that pinions b<1> turn on fixed axles and drive ring d in the reverse direction slowly. For the first speed, main sun gear c is clutched to ring e, and for reverse, sun gear c is clutched to the casing. A multiple cam device for controlling the whole gearing is described. An arrangement modified to provide space for the usual car differential comprises stepped planets in the secondary train. The friction clutches c<2>, c<3> comprise blocks r<1> thrust outwards radially by toggle struts r<2>. The blocks r<l> may, as shown in Fig. 8, be adapted to rock on the spherical outer ends of the struts 1'<SP>2> so as to jam directly against the ring e of Fig. 6. Springs s may be provided to return the blocks r<1> to mid position, and the blocks may be cut away so as to jam in one direction only. Alternatively, as shown in Fig 11, the blocks r<1> may be constrained to slide radially in a disc member r, and jamming may be effected by rollers t<1>, one between each block r<1> and the coacting ring e. United action is effected by a cage t<2> for the rollers t' returned by spring s. The blocks r<1> may be cut away so that the rollers will jam in one direction only.

Abstract: 1,236,593. Strain gauging. BRITISH AIRCRAFT CORP Ltd. May 6, 1969 [March 7, 1968], No. 11191/68. Heading G1S. A strain gauge comprises, a first member 10 having an aluminium slotted tube 26 and a body portion 12 provided with a fixing hole 18, a rod 28 of Invar steel slidably adjustable with respect to and adapted to be gripped in the tube 26 by means of tapered sleeves 32, 34, and an iron piece 30 on the rod 28 housed within the bore of a stator 43 containing primary and secondary coils, the stator being longitudinally adjustable within a clamp 40 forming part of a second U-shaped member 16 having limbs 36 and 38 and a fixing hole 22. In operation the gauge holes 18, 22 are fitted on to two taper studs fixed to the structure to be tested and the stator is connected to electrical indicating apparatus. The rod 28 is then slid along the tube 26 until the electrical indicator shows zero and fine adjustment is made by turning a screw collar 41 and moving the stator. The rod is then clamped in place by tightening a screw 50. The effective coefficient of expansion of the composite arm 14 comprising the aluminium tube 26 of the Invar rod 28 is then set to a value equal to that of the material being tested by suitably adjusting the sleeves 32, 34 along the tube 26, and the screw 50 is then loosened. The distance between the apertures 18 and 22 is now compensated for in respect of temperature change. The tube and rod may however be made of materials other than aluminium and Invar, and other electrical or mechanical devices can be used instead of the stator 43 and core 30.

Abstract: 527,513. Electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd. April 13, 1939, No. 11225. Convention date, April 13, 1938. [Class 39 (ii)] A sealing machine for uniting the stems 12 and bulbs 14 of electric lamps comprises upper and lower rotating heads 13, 10 carrying the stems and bulbs simultaneously and in alignment with one another to stations I-XVI around a turret. The heads are supported in sleeves secured to rings 15, 17 mounted on a hollow shaft 20 and are rotated by a shaft 26 which rotates a cam 25 engaging rollers 24 on a spider 16 secured to the hollow shaft. Before a head 10 with a stem 12 supported on a cap 32 on a spindle 33 is moved from station III the spindle is raised by a lever 67 to carry the stem into its proper sealing position. The lever is actuated by a cam 73 on the driving shaft 26. A fixed roller 81 at station III engages an arm on the clutch 80 to connect the driving shaft to a gear wheel 76 connected to the spindle 33 and gearing with a spur wheel 102, which rotates a shaft 104 having a gear wheel 105, which rotates a sleeve 43 carrying the claws 40 supporting a bulb. The seals are heated at stations V-XII by burners 107 and at station XIII the clutch is thrown out by engagement with a bar 113 and the rotation of the heads is stopped. Between stations XIV and XV, the track 69 is inclined to allow the spindles to separate from the sealed stems. The bulbs are held against positioning fingers 41 by the claws 40 pivoted to the fingers and engaging the end of a hollow spindle 57, which is pressed upwards by a spring 59. The fingers depend from a sleeve 43 which is normally retained in a raised position by a spring 45. The fingers and claws are moved downwards when a bulb is to be inserted by levers which engage the top of the sleeve 43 and spindle 57. The levers are actuated by cams on a shaft geared to the driving shaft.
