Title: Improvements in or relating to spinning and doubling machine spindles
IPC: B60L7/12
Filed: 1957-10-29
Abstract: 854,247. Textile spinning &c. spindle unit. KENYON & SONS Ltd., W. Oct. 29, 1957 [Nov. 1, 1956], No. 33665/57. Class 120(2). In a spindle unit for a spinning or doubling frame which includes a driving-pulley and an anti-friction idler capable of taking up two positions, so that when the unit is mounted, in the first position the idler is spaced away from the driving-belt, the driving-pulley being operatively engaged by the belt, while in the second position the idler engages the belt and moves it away from the pulley, the idler is carried by a base-plate rotatable whereby the idler may be moved between said two positions. In Fig. 4, the pulley 17 and the idler 19 are carried by a plate 10: the pulley is integral with a spindle 15 and the idler is a pulley 18 rotatable on a shaft. The plate is secured to the frame 11 when the spindle-journal 12 is placed in its support 14, in such a way that it can be rotated by a handle to either of two positions in which a spring-urged ball 25 registers with holes such as 27b in the frame. In Fig. 6, a brake 34 is secured to the frame and is spring-urged to engage the driving- pulley when the latter and the belt are disengaged. When the plate 10 is rotated so that the pulley and the belt engage, the brake is moved away by a cam 38. The shaft on which the idler is mounted may be cranked so that the displacement of the belt is a minimum and does not unduly disturb its alignment with other spindles. The arrangment may also ensure that when in its inoperative position the idler is not wholly disengaged by the belt, and in its operative position engages the belt between adjacent spindles of a pair. Means are provided to ensure that the plate 10 is swung in the appropriate direction. In Fig. 10, the idler is carried by an arm 126 pivoted by a hub 123 to a plate 116; the idler has a downward extension and the arm an adjustably-mounted brake-member 138 having a renewable shoe 141. When the plate is rotated by a handle 148 from a position in which the hub engages a stop 146 on a cam-plate 117, the idler is moved until the extension reaches the appropriate one of two holes 118, 119 in the cam, at the same time moving the belt out of operative engagement with the driving-pulley. The tension on the belt pulls the arm so that the extension engages the hole and the brake-member engages the pulley. Means are provided to limit the outward pivoting movement of the arm. The belt may be of the kind described in Specification 724,154.

Patent GB-775298-A (GB)
Title: Process for the production of tricyclodecene (5,2,1,0)-o1-8
Filed: 1953-12-03
Abstract: Tricyclodecene (5,2,1,02,6)-ol-8 is prepared by heating dicyclopentadiene in the presence of sulphuric acid of not more than 25 per cent concentration until about one third of the dicyclopentadiene remains unconverted, not more than 0.5 mol. of sulphuric acid being used per mol. of dicyclopentadiene.  The reaction is preferably carried out in a copper or copper-lined vessel.  The reaction may be discontinued when the iodine and hydroxyl numbers of the product are approximately the same, i.e. when about one third of the dicyclopentadiene remains unconverted.  Silver catalysts, preferably the hydroxide or sulphate, may be used.  The reaction may be effected by refluxing the mixture with vigorous stirring.  At the end of the reaction the sulphuric acid separates as a lower layer, the upper layer containing the product is decanted and the sulphuric acid after suitable dilution is re-used.  The upper layer is freed from acid by washing and then distilled without reflux or distilled without reflux in the presence of an alkaline substance such as calcium carbonate an alkali metal carbonate or magnesia.  The unconverted dicylopentadiene fraction from the distillation may be recycled and the crude hydroxytricyclodecene fraction purified by fractional distillation.  Examples illustrate the invention.

Abstract: 596,702. Pulse generating and modulation circuits. STANDARD TELEPHONES & CABLES, Ltd., CHATTERJEA,. P. K., AMBROSE, D. M., and BENEY, J. K. March 30, 1944, No. 33983/46. Divided out of 596,638. [Class 40 (v)] In a circuit for producing pulses having stepped leading edges, a saw-tooth wave is applied to a number of devices to generate separately timed leading edges by changing from a first to a second condition of stability and a single trailing edge by changing back simultaneously to the first condition, means individual to each of the devices being provided for adjusting the ratio of the period during which the device remains in the second condition to the period of the saw-tooth waves. The gas-filled valve V1 generates saw-tooth waves which are fed to the grid of gas-filled valve V2 which fires to generate a negative pulse, at the anode when a predetermined potential is reached, dependent on the setting- of the bias potentiometer P2, the circuit operating in the manner described in Specification 596,638. The saw-tooth wave is fed over terminal 5 to the gas-filled valves V3, V4 operating in a similar manner to 'valve V2. The anode of valve V3 is supplied from the potentiometer P4, valve V4 being' supplied from potentiometer P6. When valve V2 fires, the potential at output terminal 6 falls to an extent determined by the setting of potentiometer P4. By suitable choice of grid bias, valve V3 fires subsequently to produce a second fall in potential, the firing of valve V4 producing a third fall. The valves V2; V3 and V4 are all extinguished by the flyback voltage from valve V1 to restore the output potential to the supply voltage and end the pulse, Fig. 7 (not shown). The pulses may be inverted by an amplifying valve, Fig. 8 (not shown), and may be fed to a power amplifier, Fig. 9 (not shown), as described in Specification 596,638. The gas-filled valves may be replaced by biassed relays or multivibrators. Modulation.-By applying signal voltages at terminals 13, 15, 16 to vary the grid potential on the valves V2, V3 and V4, the leading edges may be time-modulated. A further signal may be applied at terminal 14 to frequency modulate the pulses.
