Patent GB-1097997-A (GB)
Title: Graft polymers; and the manufacture thereof
Inventor: BROOKS BRIAN WALTER
IPC: C08G81/02
Filed: 1966-06-03
Abstract: A graft polymer comprising an elastomeric hydrocarbon backbone having one or more appendant, non-elastomeric side chains in a non-terminal position, is formed by reacting a chlorinated or brominated hydrocarbon elastomer with a mono-alkali metal complex of a polymer anion.  Specified elastomers are polyisobutylene and ethylene-propylene copolymers, which may contain small amounts of polymerized isoprene or octadiene respectively, and polybutadiene. The alkali metal complex is preferably of a polyvinyl aromatic compound, e.g. polystyrene, or it may be formed from polyvinyl pyridine.  The metal is Na, K or Li and the complex is formed by polymerizing the appropriate monomer using an anionic catalyst which is an addition compound of the appropriate metal and an organic compound, e.g. butyl lithium. The metal polymer complex is reacted with the halogenated elastomer in an organic solvent to produce the graft polymer, some homopolymer being formed by reaction of the complex with impurities.

Title: Improvements in or relating to apparatus for depositing fillings into tarts, pies, pastry moulds and the like
IPC: A21C15/00
Filed: 1935-09-07
Abstract: 462,391. Filling pies and the like. CAMWHEAT PIE MACHINE CO., Ltd., and PRATT, J. Sept. 7, 1935, No. 24984. [Class 28 (i)] A machine for depositing fillings into tarts, pies, pastry moulds, and the like comprises a supply hopper, a pair of plain or serrated rollers 6 and a worm 8 for feeding the material to delivery means comprising a hollow reciprocating knife 2 which descends to sever or separate a single filling from the bulk, and a piston 3 which descends to eject the single filling from the knife 2. The machine may be driven independently and the casings 41 delivered thereto by a band or other conveyer, but, as shown, the machine is driven by the vertically reciprocating cross-head 4 of a pie machine and the casings 41 are brought beneath the depositor by the circular, intermittently rotating table thereof. The knife 2 reciprocates in a sleeve 31 and is attached to a head 32 having a spring-loaded catch plate 33 which is contacted by spaced abutments 36<a>, 35, the abutment 36<a> being fixed relatively to the cross-head 4 and the abutment 35 vertically adjustable relatively thereto by a rotary screwed rod 34. The position of the abutment 35 determines the stroke of the knife 2. A similar fixed and movable abutment arrangement associated with the cross-head 4, imparts variable vertical reciprocations to a vertical rack which is connected by gearing to the rollers 6 and worm 8 to impart variable feed motions thereto. The gearing includes a freewheel, so that the feed motions are unidirectional, and a slip safety-coupling 13 on the worm shaft. The piston 3 is raised with the knife 2 and is retained in its raised position, during the initial descent of the knife, by a disc 37 snapping past a trip 38 which is adjustable on a screwed rod 39 pivoted to the machine frame and urged towards the disc 37 by a spring. A spring loads the piston during the descent of the knife 2, and when the trip is released by the cam 40 on the head 32, forces the piston downwards in the knife and ejects the filling into the casing 41. The arrangement of parts is such that all parts in contact with the filling material are readily removable for cleaning. Cushioning pads 43 are provided. In a modification, intended for liquid fillings, such as jam, the knife 2 is provided with a valve which is closed to retain the jam inside the knife until it is opened immediately prior to the descent of the piston 3, means being provided whereby the operator may close the valve if no casing 41 is beneath the depositor.

Patent GB-587644-A (GB)
Title: Improvements in or relating to devices for locking relatively rotatable members
IPC: F16D15/00
Filed: 1944-12-15
Abstract: 587,644. Locking-levers ; friction-clutches and couplings. HISCOCKS, C. W. Dec. 15, 1944, No. 25187. [Classes 80 (ii) and 80 (iii)] Relatively-rotatable inner and outer members 24, 1, one (e.g., 24) of which may be stationary, or both rotatable, are locked together by a pair of balls or rollers 8, which are urged apart (or together) by a spring, e.g., 13, to jam in (or release from) outwardly (or inwardly) convergent spaces formed between arcuate surfaces on the members having different centres of curvature, or between convergent flat surfaces, both balls being simultaneously urged in the opposite direction for release (or locking) by a pair of arms 11 which are disposed non-radially and may be operated mechanically or electrically. In the electromagnetically-released form shown, the locking surface 2 in the outer member 1 is cylindrical about its own centre 3a, whilst that, 5a, on the inner member 24 is struck about the centre of an offset pin 6, which forms the pivot of the forked arms 11 supporting trunnions 9 of the rollers 8 and urged apart (or together) by the wire-spring 13, to move the rollers into the locking (or release) position. Release is effected by drawing the roller-arms 11 inwardly by energising windings 31 on the arms 11, and 33 on a core-member 32, fixed to the inner member 24. The arms 11 and laminated core-member 32 form a closed flux-path. As shown, the inner member 24 is fixed, and the outer member 1 is journalled on a centre-pin 3a, carried by the inner member, and carries a lever which is required to be locked. Where the inner member also rotates current is supplied through slip-rings. In a non-electric modification, Figs. 1 and 2, not shown, the roller-arms 11 are drawn inwards by turning a crank-disc which is eccentrically mounted on the inner member and is linked to both arms 11 such turning being effected by applying a handle to the squared end of the crank disc. Release of the crank-disc causes the spring 13 to spread the rollers into the locking position. Control may alternatively be effected by acting direction ; the rollers by inwardly-inclined arms forming part of a plunger, which slides radially on the outer member (Figs. 5 and 6, not shown). The application to casement windows, fanlights, ventilating louvres, revolving-doors, blinds, brake-, throttle-, and positioning-levers, and winches is referred to.

Title: Improvements in and relating to valves
IPC: F16K3/26
Filed: 1935-09-13
Abstract: 458,378. Regulating - valves. ARMSTRONG, C. H., and COPES REGULATORS, Ltd., 5, Theobalds Road, London. Sept. 13, 1935, No. 25437. Convention date, Sept. 26, 1934. [Class 135] Relates to regulating-valves, particularly to valves operated automatically by pressureresponsive or thermostatic devices or by devices responsive to water level, such as thermal elements of the inclined tube type. Specification 303,238, [Class 135], in which the valve member is both rotated and moved axially, is referred to. The casing 1, of a boiler feedvalve, for example, has an inlet 2 and an outlet 3 at right-angles thereto. A fixed member 4 with ports 6 forms a guide for a movable member 7 with corresponding ports 8 and also with small ports 11 leading to the space between the closed upper ends of the members. A projection 10 on the movable member enters an opening 9 in the closed end of the fixed member. The ports 6, 8 are inclined and lie within an annular space 12 to obviate eddy effects. Secured to the movable member is an actuating spindle 13 with a lever 16 adapted to be actuated, e.g. from a water level responsive device and a counterweight 17 may be fitted. Axial movement of spindle 13 is limited by a shoulder 18 engaging a bearing 19 secured in an extension 24 by a removable sleeve 20. A collar 21 seated against a bearing 22 secured to the upper end of the spindle forms an abutment for a spring 23 which bears'at its other end against extension 24. Downward movement of the valve is determined by an exchangeable collar 25. A pointer 26 and scale indicate the valve position. When fluid is flowing, the inlet pressure acts on the outside of member 7 and on the inner face of its closed end. The outlet pressure acts upon the projection 10. Thus, the movable member, even with high fluid pressure is subjected to only a relatively small force and is accordingly sensitive to pressure changes. With very high pressures, the flow past the ports tends to rotate the valve, but as an increase of inlet pressure produces an increased force on the thrust bearings and a consequent increased friction, the tendency to rotation is checked.

In an exchange every number called is compared with an inventory of those subscribers for which a call diverting facility is provided and on a match being detected, the dialled representation is replaced by a stored representation previously selected by the called subscriber. This is normally another representation of the called subscriber's own number but may be any other number at which he may be obtained. If a subscriber provided with the facility wishes to change the stored number he dials a predetermined code indication that he wishes to make a change. The register 30 checks the inventory at 80 that the calling station number as given by the position of the line scanner is one entitled to a call diverting facility then gives the subscriber access to the store 81. The subscriber then dials the number at which he may be obtained and this is stored in place of any previously stored representation. Numerous other facilities and features shown on the drawing are mentioned. The register has access to a translator 44 for translating dialled codes into equipment location signals. These signals may be modified in accordance with preferences set in a pre-wired assignment panel 46 and these preferences may in turn be modified in accordance with the instantaneous busy/idle states of the equipment.
