Title: Improvements in or relating to refractory compositions and processes of preparing the same
IPC: C04B35/03
Filed: 1952-05-23
Abstract: A cementitious refractory composition comprises fine magnesia, 0.25 to 5 per cent. of a boron compound calculated as B2O3 and a chromium compound, soluble in the tempering liquid in a ratio, calculated as CrO3, of from 3 to 1 to 1 to 1.5 with respect to the B2O3 component. The composition can bond acid or non-acid refractory aggregate, e.g. chrome ore, periclase, olivine, scrap brick, alumina, spinels, iron ore, graphite, singly or in admixture.  A composite product is obtained by placing a mixture of a porous insulating grain bonded by the composition in a mould on top of a layer of a mixture of dense grain bonded by the composition before the lower layer has set.  A shaped refractory can be cast in a metal mould and, after setting, remain bonded to the metal.  Specification 698,797 is referred to.

Patent GB-932338-A (GB)
Title: Improvements in or relating to the production of shaped stratified bodies
IPC: B32B27/00
Filed: 1960-04-14
Abstract: Shaped laminated bodies of rubber and a cross-linked isocyanate-polyester plastics material are made by first pre-shaping the layer of isocyanate-polyester plastics material, inserting the part thus obtained into a mould, placing a layer of unvulcanised rubber on top of the plastics material in the mould, and uniting the two by vulcanisation.  The preshaping of the plastics material layer may be carried out in the same mould, or in another mould, or by cutting or stamping out from a cast slab. The surfaces of the parts to be joined may be treated with an isocyanate adhesive agent.  That side of the body of isocyanate-polyester plastics material that is in contact with the wall of the mould may be roughened while out of the mould.  This roughening may also be extended over the rubber parts. The method may be used to make shoe linings, soles and heels for shoes, conveyer belts, roller coverings or vehicle tyres.  The parts subjected to the greatest abrasion may be of the isocyanate-polyester plastics material.

Title: Two-stage high pressure apparatus
IPC: B01J3/06
Filed: 1958-04-29
Abstract: <PICT:0845247/III/1> <PICT:0845247/III/2> <PICT:0845247/III/3> An apparatus for treating materials at high pressure and high temperature comprises a system with one pressure cell inside the other.  The second or internal stage is completely submerged in a hydrostatic pressure field generated by the first stage through a hydrostatic material such as silver chloride, silver sulphate, talc stone which changes to a generally fluid acting form under high pressures and high temperatures and the walls and gaskets of the second stage system need only support the pressure difference between the first or outer stage and the second or inner stage. The temperatures of the reaction cell is usually achieved by resistance heating and pressure is increased by movement of one or more of the punches to decrease their spacedapart dimension. Referring now to Fig. 1, there are shown tapered anvils or punches 1 and 2 of a press or any well known high pressure apparatus.  In one form the tapered punches depend from or are formed on a cylindrical structure 3.  In the press apparatus one or both of the tapered punches 1 and 2 is made movable toward the other over a predetermined path, which path is encircled by an annular ring or belt 4 of steel or other material capable of withstanding the high lateral forces developed in the apparatus.  For added protection and safety, ring 4 and the cylindrical structure 3 of the punches 1 and 2 are usually encircled by one or more additional annular rings 5 and 6 respectively.  The punches 1 and 2 together with the ring 4 define a first chamber 7 into which an additional reaction chamber 16 which is covered by an apparatus similar in construction to the outer presses is placed. The remaining space is filled with a hydrostatic material 17. Modifications of the apparatus are shown in Figs. 2 and 3. Specification 830,210 is referred to.

Title: Machine for grinding the toothed surfaces of gears
IPC: B23F5/02
Filed: 1955-05-12
Abstract: 769,161. Gear - grinding. NATIONAL BROACH & MACHINE CO. May 12, 1955 [June 14, 1954], No. 13730/55. Class 83 (3). [Also in Group XXIII] A machine for form-grinding gears has a spindle 44 for mounting the work W and rotatable in bearings 40, 42 on a slide 12 movable parallel to the work axis, relatively to the formcutter 22. A bracket 50 is rotatable in a plate 48 on slide 12 and carries a pawl 52 engaging an index-disc 46 keyed to spindle 44. Bracket 50 also carries two pins 68, 70 of conicalinvolute shape, which are held against plane surfaces 80, 82 by the constant torque applied by a motor 114 to spindle 44. The surfaces 80, 82 are carried by a slide 74 movable transversely on slide 12, as the latter reciprocates, by a follower 94 engaging an adjustable sine-bar 96. Thus, as the slide 12 is moved on a working stroke by a fluid-pressure cylinder 16, the slide 74 is moved inwards to rotate the work, through the pins 68, 70, and cause the cutter 22 to produce a true helical tooth-space on the work W. The pins are spaced angularly relatively to the work and the surfaces 80, 82 are adjustable on the slide 74 individually and jointly, to give a large range of helical angles to the workteeth. Indexing.-At the end of the stroke of slide 12, a dog 126 thereon actuates a valve 134 through a switch 122 to operate a fluid-pressure cylinder 60 on bracket 50 to disengage pawl 52 momentarily from disc 46, allowing motor 114 to index the work by one tooth. A switch 58, actuated by cylinder 60, prevents the return stroke of slide 12 from starting before the work is indexed. Crowning.-For crowning the work-teeth, the cutter 22 is offset from a position directly above the work and a member 110, adjustably secured to the sine-bar 96, has a curved surface 112 to engage the follower 94 and thus vary the helix imparted to the work.

Abstract: 974,244. Pulse signalling; transistor time delay switching circuits; supervising unattended repeaters. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. April 12, 1962 [April 17, 1961], No. 13790/61. Headings H3T, H4L and H4R. In a signalling system comprising send and receive channels each employing a plurality of repeaters SR1 to SRn and RR1 to RRn, Fig. 1, including pulse regenerators, wherein the repeaters are fed with D.C. power in series from a terminal station TSR over the signalling channels, the send and receive channels are connected together by relay-operated contacts S in each repeater station when the system is not energized, and timing equipment T controlling the relays is set in operation when the power is applied to any repeater and breaks the connection S between the channels after a predetermined time whereby the power is supplied to the succeeding repeater. Constant current power is supplied from a source CCF, and a test signal which is applied at the same time as the power passes through the regenerators and is transmitted back to the terminal station TRR over the loop at each repeater in turn and operates an alarm if an incorrect signal is detected at D. The reading of a voltmeter V across the power source CCF increases by discrete steps as the relays of successive repeaters are energized and thus provides an indication of the location of a fault. The slitht breaks in transmission as each repeater switches over may be arranged to give an audible signal. The delay device T, Fig. 3, comprises a transistor T feeding a relay S in its emitter circuit, the transistor conducting to operate the relay when the capacitor C is sufficiently charged through the resistor R.

Title: Improvements in and relating to the manufacture of artificial threads, filaments and the like
IPC: D01D10/04
Filed: 1927-05-23
Abstract: 290,833. Courtaulds, Ltd., Topham, C. F., Hazeley, E., and Morton, E. A. May 23, 1927. Treatment of material to facilitate subsequent drying.-The cake of thread formed in the box spinning process for the manufacture of artificial threads and filaments can be dried, after washing, sulphiding or bleaching, if it is deformed so that it is no longer annular in shape, with the result that all parts of the thread in the cake, whether on the inside or outside thereof, are accorded free opportunity to contract on drying without being subjected to undue tension. The cake is deformed preferably in a special apparatus. In the first type of apparatus, Fig. 1, a set of movable rods D engage the outer periphery of the cake A. whilst the inner periphery may or may not be held by a set of vertical immovable rods B. The movable rods D, which are arranged intermediate of and between the fixed rods B, are caused to move along grooves in the base plate C towards the axis of the cake by forcing down the slidable ring G encircling the rods. The cake is thus pressed at four points. more or less equidistant along the periphery, until the pressedin portions of the cake are each about one inch from the central axis. The rods are then removed and the cake transferred to the drying oven. The outside yarn of the cake is free to contract and during drying, the indentations formed in the cake become less pronounced. In the second type of apparatus, Fig. 4, the cake A is deformed by the movement of the inner rods B<1> outwards and the outer rods D<1> inwards caused by movement of the slidable ring G.
