Title: Improvements in or relating to pneumatic tyre building apparatus
Inventor: TREVASKIS HENRY WILLIAM
IPC: B29D30/24
Filed: 1962-07-03
Abstract: 1,032,394. Tyre building formers. DUNLOP RUBBER CO. Ltd. June 14, 1963 [July 3, 1962], No. 25401/62. Heading B7C. In an expansible tyre building former comprising two end members, axially movable towards and apart from each other and bridged by an inflatable member 14, which forms a tyre building surface and may be inflated to toroidal shape (lower half of drawing) to shape a tyre, the inflatable member 14, when in its uninflated cylindrical condition, is supported by axially expansible and contractible means. The supporting means shown comprises a plurality of rings 22 (only a few shown), coaxial with and mounted between the end members. Alternatively, a helically-wound spring could support member 14. As shown, an external bellows 15 and an internal bellows 16 extend between the end members forming a chamber 18, which is pressurized or evacuated to move the end members relatively apart or together, through a pipe 20. A pipe 21 permits inflation of the member 14. Each end member comprises axially inner and outer portions 3, 5, relatively movable together against a spring 7. End stops 2a and central stop 17 limit movement of the end members. Each portion 3 of an end member carries expandable bead locating means 9 . . . 12, and inflatable diaphragm 14 is sealed to portions 5. Alternatively, end members may comprise one portion only, having bead location means axially outward of the diaphragm ends. The internal bellows 16 could be replaced by a rubber ring between each end member and the shaft 2. In use, tyre ply 24 is built up on the axially expanded former (top half of picture) the rings 22, one between each convolution of bellows 15, maintaining the diaphragm 14 cylindrical. Bead wires 25 are positioned and bags 12 inflated to grip them. The diaphragm being axially inextensible, inflation of bags 12 causes portions 5 of the end members to moving inwards holding the diaphragm taut. The ply ends are turned up, then the diaphragm 14 is inflated while chamber 18 is partially evacuated, drawing the end members together (lower half of picture). The pressure conditions are maintained while the former is rotated during application of sidewalls and tread, then reversed to deflate the diaphragm and axially separate the end members, prior to removing the raw tyre.

Title: Period meter and logarithmic ratemeter
Inventor: VINCENT CHARLES HOLMES
IPC: G06F19/00
Filed: 1963-06-28
Abstract: 1,045,975. Electric selective signalling; counters. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. June 22, 1964 [June 28, 1963], No. 25806/63. Headings G4A and G4H. In a period meter or a logarithmic ratemeter pulses are counted by a sealer during successive time intervals and fractions of the number in the sealer are successively subtracted until a predetermined value is reached. The number of subtractions made is proportional to the logarithm of the count-rate and the difference between the number of subtractions made for two successive time intervals is proportional to the reciprocal of the period of the input pulses. The apparatus is timed by pulses from an oscillator fed into a sealer followed by 0, 1 or 2 extra binary stages and 0, 1, 2 or 3 extra decimal stages selected by switches to alter the duration of a cycle. Pulses from a neutron detector in a nuclear reactor are counted by a sealer which operates top or bottom level displays if the count is more or less than given threshold values. Fractions of the number counted are subtracted successively until the lower threshold level is reached and the number of subtractions made are counted by two sealers. The contents of the one of the two sealers which was the last reset is complemented such that the difference is found between this number and the number counted after the next time interval count, the sealers being reset alternately. The result of the subtraction between the two counts, complemented if negative, is displayed in decimal form on neon tubes with its sign to represent the reciprocal of the period of the input pulses. In a binary coded decimal sealer (Fig. 1, not shown) a gate 106 is closed when the count of 8 is reached and the count of 10 is obtained through a line 115 to give a carry pulse to the next decade and a pulse to re-open gate 106. Complementing carry gates 107-109 are closed and pulses applied through gates 110- 112 on lines 114 and then 113 to change the " 1 " digit, not the " 2 " digit, the " 8 " digit if the " 4 " and " 2 " digits are both 0 and the " 4 " digit if the " 2 " digit is a 1.
Patent GB-1036752-A (GB)
Title: Process for improving textile material consisting at least partly of cellulosic fibres
IPC: D06M13/285
Filed: 1963-06-28
Abstract: Textile materials comprising cellulosic fibres, e.g. cotton yarns and fabrics, are crease-proofed and given improved dimensional stability by producing on them, preferably when they are in an at least slightly swollen state, a rearrangement of the yarns and fibres thereof by uniformly stretching them by at least 30% of their extension at break in the stretched direction, the stretching being carried out in small to infinitely small areas by p  exerting mechanical pull between points which are at a small to infinitely small distance from each other, and then crosslinking the cellulosic fibre material.  The stretching which may be carried out at room or elevated temperatures may be effected by causing the material to form curves of small length perpendicular to its original surface to orginal dimensions measured in that plane remaining substantially unchanged, by means of pairs of bowls or plates with surface structures arranged at a small distance from each other the surface structures consisting of ridges in one surface alternating with grooves in the other, by pressing the material between two elastic bodies or one elastic and one inelastic or less elastic body, e.g. bowls, belts, blankets or plates, so that the material is stretched in the desired directions or by stretching the material between bowls or other bodies having differing surface speeds one of which preferably has a relatively high friction coefficient towards the textile material.  Stretching may be effected during, after or prior to washing, bleaching, dyeing or caustic treatments or in the presence of the cross-linking agents and may be carried out in a series of steps.  Crosslinking may be effected by treatment with synthetic resin precondensates of formaldehyde, glyoxel or acrolein with urea, cyclic alkylene ureas, ureino or triazones aldehydes, acetates, enol ethers, di-or polyfunctional compounds containing epoxy-isocyanate- or vinylsulpho groups, polyhalides, halohydrino, dicarboxylic acids, sulphonium, phosphorium and oxanium compounds or reaction products of ketones with aldehydes which are applied with acid, basic potentially acid or basic catalysts, radical producing compounds or radiation, polyethylene softeners, dyestuffs and pigments, followed by drying and curing. Alternatively cross-linking may be effected by irradiation, substitution reactions, graft polymer formation, formation of polymers in situ or depostion of polymers within the fibres. Crosslinking may be carried out in several steps. Stretching may be carried out at a small angle to the yarns to be stretched. Prior to or after stretching the materials may be subjected to mechanical or chemical shrinking.

Title: Improvements in and relating to containers for radio active isotopes
IPC: G21F5/015
Filed: 1959-07-28
Abstract: 919,643. Containers for radio-active material. PONTET, H. C. July 25, 1960 [July 28, 1959], No. 25878/59. Class 98 (1). A container for radio-active material comprises two interengageable lead-lined casings, one being rotatable and adapted to contain the said material, the other being slidable, such that when in interengagement, the two form a completely surrounding shield for the material, and lever and cam means for sliding away the one casing and rotating the other so as to expose the material for use. In the form shown, the two casings are hollow containers 6, 9, having respective lead linings 7, 10. The radioactive material is placed in a container 22 mounted at the end of a plug 21 which can be inserted into the upper casing 9 through a bore 20. The upper casing can pivot on trunnions 13, and is conveniently swung thereon by a handle 15. The lower casing 6 is mounted on a plate 3 which is supported on telescoping tubes 4, 5 housing coil springs, so that casing 6 can move up and down. The mating surfaces of the upper and lower casings are generally convex and concave respectively, and are formed with a series of concentric steps 11, 12. When the casings are in the closed position, as shown, these two series of steps are urged into close contact by the spring action of the telescopic tubes 4, 5 on casing 6, the lead linings forming a substantial shield completely enclosing the radio-active material. When a pull is applied to handle 15, a cam and roller arrangement (Fig. 2, not shown) first causes casing 6 to be pushed downwards until it is clear of the upper casing, and then casing 9 is swung through 90 degrees, thus bringing the container 22 into an outward-facing operative position. After use, these operations are reversed by pulling the handle the other way. A cross-bar 26 on the handle 15 prevents the radio-active material from being removable when the container is in the closed position. It may be locked in this position by a latch bolt, operated from a key-lock 28, which prevents lower casing 6 from moving downwards.

Title: Drive mechanism particularly for engine accessories
IPC: F01P7/04
Filed: 1958-08-13
Abstract: 898,441. Hydraulic couplings. EATON MANUFACTURING CO. Aug. 13, 1958 [Aug. 26, 1957], No. 25983/58. Class 69 (2). An hydraulic coupling for driving an accessory, such as a fan 10 or generator from an internal-combustion engine comprises first and second members 21, 25 supported for rotation about a common axis, and a fluid chamber 24 defined by portions of the second member on opposite sides of the first member and the outer periphery of the first member, the members having spaced opposing surfaces co-operating with a high viscous oil in the chamber to provide a shear type fluid drive. The first member 21 is pinned to a shaft 15 connected to a pulley 16 driven from the engine and has on one surface spaced flanges 42 which are disposed within grooves on the second member 25 formed from two parts 26, 27 secured together by bolts, the flanges being spaced from the part 26 at all points. The member 25 is supported by a single bearing 30 on the shaft 15 and is bolted to the fan 10. A high viscous fluid, such as silicone oil, is contained within the chamber 24 and is thrown outwardly by centrifugal force into the outer portion of the chamber during rotation of the first member to form the sheartype fluid drive between the members. The opposed surfaces of the members are closely spaced and the fluid therebetween during rotation tends to prevent wobble of the fan and to damp vibrations and oscillations in the coupling. In other embodiments, a radially extending flange on either the first or second member replaces the ridges and grooves, the spacing between the flange and the opposing member being small to provide the damping effect. The external surfaces of the parts 26, 27 are formed with fins to assist cooling of the coupling. Specification 898,443 is referred to.
