Title: Improvements in and relating to machine tools
Inventor: CHILDS LESLIE ANDREW
IPC: B23B31/02
Filed: 1955-08-26
Abstract: 773,286. Draw-spindle mandrels. CRANE, Ltd. Aug. 26, 1955, No. 24560/55. Class 83 (3). In a machine-tool or attachment therefor having an externally, or internally, screwthreaded arbor 3 for supporting work X, and a draw-bar 2 for displacing the arbor to grip the work against a stop-plate 22 on the machinespindle 1, means 5, 7 converts axial-movement of the draw-bar into rotational-movement of the arbor through step-up gearing 9, 10, 17 to facilitate application and removal of the work. The arbor 3 is connected, through dogs 27 and a screw 26, to the extension 25 of a shaft 11 supporting the sun-gear 10 which meshes with one or more planet-wheels 9 on a flange 6a of a sleeve 6, the shaft 11 being joumalled in a housing 13 screwing in the end of the sleeve 6a and secured thereto by lock-nuts 16. An internal-gear 17, meshing with the planet-wheels 9, is bolted at 23 to the stop-plate 22 and at 20 to a ring 18 attached to the spindle 1. The draw-bar 2 acts through a shaft 4 having a spiral-groove 5 engaging pins 7 or a thread on the sleeve 6, which has a shoulder 35 engaging the head 36 of the shaft 4 in the retracted position depicted of the draw-bar. To reach this position, the work is screwed on to the arbor by one turn and then held lightly by the operator while the draw-bar is retracted within the sleeve. This produces rotation of the arbor 3 until movement of the head 36 of bar 4 is terminated by the shoulder 35; the draw-bar, sleeve, sun-and-planet-wheels, arbor and work then move together to bring the work into engagement with the stop-plate. During the releasing operation, the work is again held lightly by the operator while the draw-bar is advanced, the sleeve 6 and arbor assembly accompanying the draw-bar under the influence of a spring 31 until the work is freed from the stop-plate and motion of the sleeve is arrested by a thrust bearing 39 on the sleeve contacting the ring 18; further movement of the draw-bar rotates the sleeve and screws the arbor out of the work. Alternatively, the work may be brought into driving-engagement with the stop-plate 22 while the mandrel is rotating.

Patent GB-777248-A (GB)
Title: Improvements in or relating to ion exchange substances
Inventor: KENNEDY JOHN
IPC: C08F8/00
Filed: 1953-09-07
Abstract: Ion-exchange resins are made by partial hydrolysis of a polymeric diallyl-lower alkyl or triallyl phosphate.  The lower alkyl group contains up to 5 carbon atoms, e.g. methyl and ethyl. Hydrolysis may be effected by refluxing with aqueous or alcoholic alkali metal hydroxide, washing with water and drying.  The product may be repeatedly washed with sulphuric acid and then with water until the wash-water is free from sulphate ions to convert the resin to the acid form.  In examples: (1) triallyl phosphate is polymerized in the presence of benzoyl peroxide at 100 DEG  C. in a sealed vessel and the product crushed to 30 to 70 mesh size and washed with acetone; (2) triallyl phosphate containing benzoyl peroxide is heated with water under reflux with vigorous stirring to form polymer beads which are similarly washed.  The resin absorb ferric more strongly than uranyl ions, which may be eluted from the resin with aqueous ammonium carbonate solution, leaving ferric ions which may be subsequently eluted with dilute sulphuric acid containing sulphur dioxide.  U.S.A. Specification 2,394,829 is referred to.ALSO:Ion-exchange resins made by partial hydrolysis of polymeric diallyllower alkyl or trialkyl phosphates absorb ferric more strongly than uranyl ions, which may be eluted from the resin with aqueous ammonium carbonate solution, leaving ferric ions which may be subsequently eluted with dilute sulphuric acid containing sulphur dioxide.

Title: Improvements in or relating to oxygen rescue apparatus
IPC: A61M16/00
Filed: 1936-09-10
Abstract: <PICT:0464571/III/1> <PICT:0464571/III/2> <PICT:0464571/III/3> In oxygen rescue apparatus in which the oxygen supply is obtained from a container a holding a composition generating oxygen by thermal decomposition and provided with a striking pin b acting on a primer to initiate the decomposition, the container is mounted in a box d and secured to a pivot m at the end remote from the striking pin which is closely adjacent to one wall of the box and thus cannot be actuated.  To use the apparatus, the container is pivoted upwardly to expose the pin.  Preferably, the container is locked in the upward position and the locking means are only released by removal of the container.  Two containers are preferably mounted in the box as shown in Fig. 3 and are provided with pipes f and g to lead the oxygen into a common delivery pipe k.  These pipes are held by springs, for example f<1> in a position in which valves h and i are closed when the screw couplings of the respective pipes are disconnected.  Fig. 4 shows one form of safety catch actuated by the striking pin b.  When struck, the spring bolt t is retracted by arm t<2>, and releases the nose p<4> of the swivel plate p.  This plate is then moved by spring p<1> into a position in which nose p<2> abuts against the container a and nose p<2> is interposed over the wall of the box and prevents the container from being lowered.  At the same time, nose p<4> snaps into catch u<6> thus preventing return of the swivel plate p into its original position.  When the container is removed, the plate p is rotated further by the spring and nose p<4> presses back the nose u<4>, thus holding catch plate u in an inoperative position, since nose p<6> engages in the depression shown. The swivel plate can thus be returned to its original position where nose p<4> engages the bolt t.  In the form shown in Fig. 5, on raising the container, the catch is locked above the base plate c by the spring v.  On disengaging the oxygen pipes f and g, lateral extensions f<2> and g<2> on the valve cones of cocks h and i force the catch r back to its original position. Specification 451,170 is referred to.
