Patent GB-1126926-A (GB)
Title: Improvements in or relating to textile processing apparatus
IPC: B65H67/04
Filed: 1965-09-27
Abstract: 1,126,926. Sliver coilers. MAREMONT CORP. 27 Sept., 1965 [1 Oct., 1964], No. 41033/65. Heading D1F.  A sliver can doffing apparatus comprises a filling station and a full can storage station, separated by a horizontal surface providing access by an operator to the filling station while a full can is positioned at the storage station, transfer mechanism for moving a full can from one station to the other and selective control means responsive to the weight of the operator to suspend operation of the mechanism. In operation of the automatically controlled apparatus shown, and positioned, for example, at the delivery end of a sliver drawing frame, empty can conveyor rolls 20 (in the absence of a can at empty can ready station E) are driven by reversible motor 25 to move can(s) from empty can storage positions R<SP>1</SP> and R<SP>11</SP> to station E until an empty can actuates a ready switch 34 to stop the drive to rolls. If positions R<SP>1</SP> and R<SP>11</SP> become empty, doffing is automatically suspended. On completion of the supply of a measured quantity of sliver into a can at coiling station F (or manual operation of a push-button 106) delivery rollers 16, 17, and coiler 15 including turntable 40 are stopped and the can changing cycle is initiated. After a time delay and provided there is not a full can or an operator at the access station on stand plate 50, the doff arm 72 swings to move the can to station A: simultaneously therewith the sliver is severed by the friction snubbing action of a hook and a gripping comb, Figs. 7 and 8 (not shown) so that a hanging end thereof is in readiness for the next filling operation. When the can transfer is completed arm 72 returns and, provided a full can sensing switch 82 is closed, motor 25 runs in reversed direction so that chain mounted lug 86 (raised by a cam into engagement with the underlip of the lower rim of the can) ejects the can from station A to the full can storage station S, whereafter further operation of motor 25 is suspended until the can is removed from the apparatus. When arm 72 completes its return, don arm 62 swings to move the empty can at E to station F on turntable 40: as arm 62 returns, the sliver delivery and coiler mechanisms are .restarted and, on completion of the return movement, a limit switch 67 is operated to permit the positioning of another can at E as before. Thus, nearly three cans may be filled before one need be removed. The sequence of operations is controlled by a system of limit and sensing switches, relay controlled, pneumatic doff and don cylinders, and electrically-operated valves therefor, Fig. 9 (not shown).

Abstract: 989,217. Turbine blades. GENERAL MOTORS CORPORATION. Oct. 17, 1963 [Dec. 5, 1962], No. 41037/63. Heading FIT. A turbine blade includes a hollow aerofoil the opposite walls of which are joined by struts which extend across the blade thickness at an angle to the longitudinal axis of the blade and act as guide vanes which, in conjunction with the blade walls, form coolant flow passages which are directed at a blade edge and are convergent in the direction towards the blade edge. A hollow turbine rotor blade has a transverse passage 28 in the shank 14 through which cooling air is supplied to the interior 26 of the blade. Pairs of vanes 32, 321 and 36, 361 joining the walls 18, 20 of the blade 10 form converging nozzles to direct the cooling air on to the trailing and leading edges 24, 22 of the blade respectively. Larger vanes 30, 30<SP>1</SP> and 34, 34<SP>1</SP> direct the air into the nozzles and are preferably inclined at an angle of 20 degrees, whereas the vanes 32 are inclined at 45 degrees. The directing vanes are cast with the walls 18, 20 and act as supports thereof. In a modification Figs. 5 to 7 (not shown) triangular section vanes are provided in conjunction with longitudinally extending ribs. In a further modification, Figs. 8 and 9 (not shown) some of the ribs are inclined towards the leading and trailing edges of the blade. The invention is also applicable to turbine stator blades.

A process for forming regenerated cellulose filaments comprises the steps of (a) forming a viscose solution by treating alkali cellulose with carbon disulphide in presence of a surface active agent to obtain cellulose xanthate; (b) spinning the viscose into a bath at a temperature of at least 25‹ C., containing 3 to 30 g/l. of sulphuric acid and 0.1 to 2.0 g/l. of at least one heavy metal sulphate, the viscose, before spinning, being brought to a temperature which is less than that of the bath by not more than 10‹ C.; (c) positively and continuously drawing the filaments during regeneration of the cellulose in such a manner that the tension on the filaments is progressively increased. The surface active agent may be anionic e.g. 40% sulphonated ricinolein, cationic e.g. addition compounds of an alkylamine or alkylamide with ethylene oxide, or non-ionic e.g. addition compounds of a higher alcohol with ethylene oxide. The heavy metal sulphate may be e.g. Zn, Co, Ni, Cr or Cd sulphates.

Abstract: 956,266. Transistor pulse generating circuits. WESTERN ELECTRIC CO. Inc. Dec. 7. 1961 [Dec. 27, 1960], No. 43804/61. Heading H3T. An energy storage device 11 is charged through a Zener diode 19 and inductor 18 and discharged through a switching device 10 so as to produce output pulses 11. The capacitor charges at a rate determined by a resistor 21 until its voltage reaches a value at which the Zener diode 19 becomes substantially non-conductive, whereupon the charging is completed by the collapse of the field of an inductor 18. A bleed resistor 17 maintains the working point of transistor 10 at such a value that a positive pulse 1 at the base will cause avalanche breakdown to occur and the capacitor to discharge. The trailing edge of the triggering pulse causes a diode 3 to conduct and returns the transistor to its initial lightly conducting state so that the capacitor recharges. The inductor prevents a heavy current flow through the transistor from the Zener diode when the transistor is rendered conductive.
