Title: Improvements in or relating to chucks
Inventor: RIDOUT EDWARD DAVID
IPC: B23B31/167
Filed: 1953-12-01
Abstract: 764,593. Chucks. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Nov. 19, 1954 [Dec. 1, 1953], No. 33300/53. Class 83 (3). [Also in Group XXIII] A chuck for holding circular or non-circular work, particularly for glass-working lathes, comprises more than two jaws, means for guiding the jaws radially, and operating-mechanism including a pair of rotary members and driving mechanism common to both the rotary members, rotation of the latter causing simultaneous movement of the jaws and continued movement of one or more jaws after one of the other jaws has been arrested by engaging the work. A circular-base member 1, Fig. 2, has an annular recess 5 into which fits three concentric rings 6-8. A cover-plate 9 encloses the rings and supports four slides 10 having jaws 11-14 respectively clamped thereto. The slides are spaced 90 degrees apart and are constrained by guides 10a to move radially. The middle-ring 7 has, attached to its underside, an arc-shaped rack 23 which engages a pinion 24 actuated by a wheel 26. The three rings are connected by levers 20, Fig. 1, which permit limited relative angular movement. The inner ring 8 has opposite cam-grooves 17, 18 which engage pins 21 extending below the jaw-slides 10 for the jaws 12, 14; similarly the outer ring has cam grooves controlling the jaws 11, 13. On rotation of the wheel 26 to close the jaws, one pair of jaws makes contact with the work and the rings then move relatively until the other pair of jaws makes contact, the levers 20 rocking on the ring 7. Preliminary adjustment of the jaws is made on the slides 10 so that they are set open slightly greater than the two major dimensions of the work, such as'a rectangular bulb for a cathode-ray tube. The hub 3 of the chuck may be formed as a vacuum chamber 4 for temporarily or partially holding the work during centring.

Abstract: 1,194,859. Laminated articles. BRUSHED PLASTICS Ltd. 20 July, 1967, No. 33359/67. Heading B5N. The flat surface on an article 10 is indented so as to form a number of intersecting channels 11, 12, and a thin plastics or metal film 13 is adhesively secured in stretched condition over the surface so as to leave intercommunicating spaces in the channels. The article may be of expanded polystyrene, cardboard, insulation board or wood and the film may be of polythene, p.v.c. or other soft plastics material. The article may be indented after the film has been arranged over its surface, in which case recovery of the film produces spaces 15 at the bottoms of the channels. Preferably, an adhesive comprising globules 14 in a volatile vehicle, such as a polyvinyl acetate emulsion, is used so that even on the raised portions of the indented surface spaces exist between the globules through which gases may pass to the spaces in the channels, thus avoiding the formation of blisters under the film.

The primer comprises tetrazene or tetrazene tricinate. The cartridge is made by introducing wet or dry primer composition into the bore in the propellant charge and compressing it from both ends with dies having a diameter equal to the diameter 5. Excess primer composition is displaced between the dies and the wall of the passage but is constrained from being forced behond the end faces of the propellant charge.

Patent GB-344873-A (GB)
Title: Improvements in the manufacture of artificial silk
IPC: D01F2/28
Filed: 1929-11-08
Abstract: In the manufacture of artificial silk, threads or filaments spun from cellulose derivatives or a cuprammonium solution of cellulose are first treated to remove beta and gamma celluloses or cellulose derivatives, then treated with a swelling or plasticizing agent and stretched, the swelling or plasticizing agent being then removed. The purifying treatment is applied at any stage during or after formation of the filaments but before final stretching.  Preliminary stretching may be applied during formation or coagulation of the filaments.  In examples: (1) Cellulosic threads prepared from viscose, cuprammonium or cellulose nitrate are treated at 50-60 DEG C. with a 6-10 per cent solution of caustic soda containing a neutral salt e.g. 6-12 per cent of Glauber's salt; after washing free from soluble products, the threads are treated with a suitable swelling agent e.g. zinc chloride, thiocyanates, sulphuric, hydrochloric or nitric acids, or ammoniacal copper solution, and stretched; while under stretch, the swelling agent is removed.  (2) Threads from an acetone-soluble cellulose acetate are extracted with aqueous acetone of 50-80 per cent strength to remove beta and gamma cellulose acetates and are then swollen with known swelling agents and stretched, the swelling agent being removed while the threads are under stretch.  Suitable swelling agents comprise dilute acetone or acetic acid of less than 50 per cent strength, lactic acid, zinc chloride, thiocyanates, sulphuric and phosphoric acids, and ammoniacal copper and nickel solutions.  The following matters are disclaimed-treatment of artificial silk threads with caustic alkali followed by removal of the alkali; treating filaments with alkali and stretching; the production of viscose and cuprammonium solutions from purified cellulose; purification of formed threads by treatment with agents capable of dissolving out the beta and gamma celluloses or other soluble products; and swelling or plasticizing followed by stretching and subsequent removal of the swelling or plasticizing agent.  Specifications 229,678, 271,517, and 319,291, [all in Class 2 (ii), Cellulose &c.], are referred to.

Abstract: 507,158. Automatic guns. BIRKIGT, M. Dec. 9, 1937. No. 34135. Convention date, June 21. [Classes 92 (ii) and 119] [Also in Group XXIV] , . A moving member which is under the action of a powerful force and which has to be locked, e.g. the breech-block 1 of an automatic firearm, has the locking catch positively moved into full engagement with a stop on the member to be locked during the final part of the movement of the member to locked position. The catch 3 is pivoted at o in a slide 5 which is permitted a short movement against the resistance of a stiff spring 6 and a buffer pad 8. At the commence - ment of the return movement of the breechblock 1 after a discharge, the catch rides in a groove 1<1> until engaged by the end face 4 of the groove, whereupon the catch and slide 5 make a short movement which causes a stationary roller 11 to engage a ramp 3<2> on the catch and urge the catch into full engagement with the face 4. The spring 6 then returns the slide against the action of the recoil spring 2, to free the catch from the roller 11, ready for operation by the rod 10. The operative face of the catch is an arc with the pivot o as centre.

Abstract: 1508817 Hydraulic control circuits; reciprocating pumps APPLIED POWER Inc 19 Aug 1975 [30 Aug 1974] 34453/75 Headings F1A and F1P In an hydraulic circuit, Fig. 2, for tilting a vehicle cab 10, Fig. 1, through an over-centre position by double-acting rams 24, hydraulically operated latches 18, 20 are provided for locking the cab in the lowered position and the hydraulic pump 32, Fig. 2, is driven by a pulsating pneumatic motor 34. A rotary control valve 44 directs hydraulic liquid to the rams 24 and to actuators which move the latches to a disengaged position against the force of springs which hold them in the engaged position. The actuators operate at a lower pressure than the rams 24 so that they are disengaged before tilting commences. A device 51, Fig. 10, includes a ball-valve 67 which holds pressure in the lines to the latches when the cab goes over-centre. When the cab returns to the lowered position it depresses a plunger 83 which unseats the valve 67 to ensure that the latches are again engaged by their operating springs. The control valve is a three-position rotary valve, Figs. 3-5 (not shown), and in the neutral position the rotary core is urged towards the reservoir port to minimize leakage. The pump comprises a piston 146, Fig. 7, which draws liquid through a pipe 40 from a reservoir 38 past a check-valve 152 and pumps the liquid through a check-valve 156 into a conduit 160. A relief valve 159 is provided. A manually operated reciprocating pump 170, Fig. 6, is provided in case of power failures.
