Abstract: 846,225. Tyre building drums. GENERAL TIRE & RUBBER CO. Dec. 15, 1958 [Jan. 2, 1958], No. 40434/58. Class 144 (1). In a tyre building drum comprising two coaxial, axially-adjustably spaced radially expansible cylindrical end-sections 4, 5 bridged by a cylindrical series of overlapping arcuate resilient sheet-metal segments 20 telescoped over adjacent ends of the end sections 4, 5, each segment 20 overlaps, and is overlapped by, respectively, the two adjacent segments, and the segments 20 are radially expansible with the end-sections against the radially inward pull of a pair of helically-coiled garter springs 29 which are connected at axially and circumferentiallyspaced points to rubber blocks 21 bonded one to the underside of each segment 20. As shown, the segments 20 each overlap and underlap respectively the two adjacent segments 20 and each has a rectangular rubber block 21 bonded to its underside to extend circumferentially closely adjacent the underlapping end of an adjacent segment. The blocks 21 extend axially between the adjacent end flanges 10 of the drum end-sections 4, 5 to limit axial displacement of the segments and each has a circumferential rib 23 projecting radially inwardly from each side edge. The ribs 23 each have a tubular metal bush extending transversely therethrough at each end to anchor the ends 27, 28 of a wire loop 26 to which the associated garter spring 29 is linked. Consequently, each segment is linked to each of two axially-spaced garter springs 29 at two circumferentially-spaced positions. The blocks 21 may be covered with nylon fabric.

Title: Improved catalyst and polymerisation process using said catalyst
IPC: C08F4/06
Filed: 1960-12-01
Abstract: Olefinically and acetylenically unsaturated organic compounds are polymerized to oligomers using a catalyst comprising an elemental alkali metal deposited on a lamellar complex, said complex consisting of or containing a dissimilar alkali metal and carbon, the carbon preferably being wholly or partly in the form of natural or synthetic graphite.  Preferably the complex consists of or contains potassium, rubidium or caesium, or two or all three of these metals and the elemental alkali metal deposited on the complex is preferably sodium or lithium or both of these metals, the amount of elemental metal deposited preferably being in the range 1-20% by weight based on the complex.  A preferred catalyst consists of elemental sodium deposited on a complex of potassium and carbon, e.g. KC8, KC16, KC24, KC36, KC48 or KC60 or mixtures thereof or complexes of higher carbon to potassium ratio.  The catalyst may be formed by pre-forming a lamellar complex by heating a mixture of alkali metal and carbon and thereafter heating the complex so formed with a different alkali metal or by mixing together (a) an alkali metal selected from sodium and lithium, (b) an alkali metal selected from potassium, rubidium and caesium and (c) carbon in a form which is capable of forming a lamellar complex with an alkali metal, and maintaining the mixture under conditions such that lamellar complex formation takes place. In the polymerization the catalyst may be preformed or formed in situ and the catalyst may consist wholly of an alkali metal deposited on a lamellar complex or may consist of or contain a mixture of this material with (a) alkali metal and/or (b) carbon and/or (c) a lamellar complex.  The preferred olefinic unsaturated compounds are olefinic hydrocarbons, preferably openchain mono-olefines, but dienes, polyenes or styrene may also be used, the polymerization temperature usually being from -10 DEG  to 400 DEG C. and the pressure from 50 to 400 p.s.i.g.  The polymerization may be carried out in the presence or absence of a solvent, e.g. normal heptane, and in the example propylene is dimerized using the above preferred catalyst to give a mixture of hexenes containing 29% of 4-methyl-pentene-1 and 60% of 4-methyl-pentene-2 together with minor amounts of other hexenes.

Title: Apparatus for testing rubber

Filed: 1958-12-23
Abstract: 881,567. Linkwork. RESEARCH ASSOCIATION OF BRITISH RUBBER MANUFACTURERS, and WALLACE & CO. Ltd., M. W. Dec. 22, 1959 [Dec. 23, 1958], No. 41577/58. Class 80 (3). [Also in Group XIX] In a rubber-testing machine (Group XIX), a sinusoidal reciprocating motion of constant but adjustable amplitude is generated. A shaft 39 is rotated at a constant speed by an electric motor driving a sprocketwheel 100. The shaft 39 carries a disc 10 on which is mounted a block 49 slidable in guides 55 and having a projecting pin 9. This latter engages with a slipper 59 slidable vertically in a slipper block 8 which is constrained to move horizontally. The slipper block 8 imparts the desired motion to the test piece. The block 49 has a slot 54 engaging a pin 45 eccentrically mounted on an inner rod 38 which can be adjusted relatively to the shaft 39 by a knob 40 incorporating a pointer. This can be read against markings on a dial 43 rotating with the shaft 39. A spring 44 prevents relative rotation of the rod and the shaft other than during adjustment. Thus rotation of the knob 40 slides the block 49 along the guides 55 varying the eccentricity of the pin 9, and so altering the amplitude of oscillation of the slipper block 8.

Title: Phase comparator
IPC: G01R25/00
Filed: 1975-10-14
Abstract: 1477584 Phase comparators MULLARD Ltd 14 Oct 1975 42033/75 Heading H3A A phase comparator comprises : a sampling switch 16 operable for a given period by each occurrence of a given edge of a first input signal at 21; a ramp generator 13 triggered by each occurrence of a given edge of a second input signal at 11 to produce a waveform having a ramped leading edge of predetermined slope occupying less than 180 degrees of the waveform, the sampling switch sampling this waveform; a hold circuit 20 which stores the sampled value between samples to provide an analogue output; and a detector which responds to disconnect the analogue signal from the output if the sampling switch is operated other than during the ramped leading edge. The output from ramp generator 13 is also applied to an end of ramp detector 36, the output from which is applied to a logic circuit 31 together with the two inputs 11, 21. When the two signals 11, 21 have the same frequency and the phase difference is such that the sampling pulses occur during the ramp signal, then the logic circuit causes gates 46, 47 to block and gate 41 to open to feed the signal stored on capacitor 20 to be fed to output 48. If the sampling pulse is outside this range, then either gate 46 or 47 is enabled to connect - V or + V to the output 48. The comparator is used in a phase locked loop system, the application of the - V or + V signal ensuring that the variable signal rapidly returns to the lock in range. The generator 13 produces a trapezoidal waveform having both a ramped leading and trailing edge and the generator 23 produces a sampling pulse only for sampling the leading edge. In a modification, Figs. 6-11 (not shown), both ramp edges are sampled and stored, using separate sample-and-hold circuits.
