Abstract: 1,191,915. Accumulator drum. BRITISH INSULATED CALLENDER'S CABLES Ltd. 14 Nov., 1968 [15 Nov., 1967], No. 52010/67. Heading D1F. An accumulator for temporarily storing wire comprises a driven drum 3 that is supported at one end and has a driven wire paying off flier 18 at the other end, the arrangement being such that whilst wire is being wound onto the drum by an input guide 4, wire can be fed off the drum via the flier 18. A screw threaded collar 24 may act on a spring 23 to press the flier 18 against a friction disc 22 at the end of drum 3, the pressure of the spring 23 being preferably set such that the flier rotates at a speed slightly less than that of the drum 3 which may be driven by a handle 17. The flier and the drum could be driven from the same or different electric motors and the various drivers intercoupled or the various motors controlled to drive the apparatus as described. The input guide 4 may be mounted on a traverse screw 14 driven by the drive to the drum 3. In a modified construction the drum is traversed relative to the guide 4. Alternatively the drum 3 is formed with a helical groove so that the wire is automatically distributed. Wire drawn from flier 18 passes between vertical rollers 10, 11 under L-shaped guides. The wire may be driven into the guide 4 by means which stops the drum 3 if the tension of the wire on the input side falls to a low value.
Patent GB-520971-A (GB)
Abstract: 520,971. Knitting machines. BENTLEY ENGINEERING CO., Ltd., and MANGER, C. F. Nov. 5, 1938, No. 32122. [Class 74 (ii)] Means are provided for disengaging an elastic or other additional yarn from a positive yarnfeeding device when the yarn is to be knitted instead of being laid in as a weft. Additional means are provided for rendering the yarn feeding device inoperative, as, for example, when the yarn is not to be supplied to the needles. The additional yarn 60 is fed by pinions 39, 40, one of which rotates with a friction disc 33 which can be made to engage a rubber-edge driving friction wheel 34. A rod 16 mounted co-axially and within the hollow driving shaft for the wheel 34 can be moved to engage a cam face 32 upon a bracket 30 by a cam 22 having lifts of three radii. With the cam follower 24 upon the lift 120, the disc 33 and wheel 34 are in contact, and the feeding pinions 39, 40 are in mesh. When the follower 34 moves on to an intermediate lift 121 movement of the bracket 30 causes the friction disc 33 and wheel 34 to become disengaged so that the drive for the pinion 40 is interrupted. The pinions 39, 40 remain! in mesh so that the yarn is gripped between them, and feeding of the yarn cannot take place. Movement of.the follower 24 on to one of the high lifts 122 rotates the bracket 30 further so that a bell-crank lever 53 carried by it is rotated to move a. second lever 38 carrying the pinion 40. The yarn 60 is thus freed from the pinions and can be pulled off as required by the needles in knitting. A yarn-tensioning device comprising two discs 61 held together by a spring is provided between the positive yarnfeeding device and the needles.

Abstract: 1,155,192. Safety devices for jib cranes. G. W. SPARROW & SONS Ltd. 29 Nov., 1966 [14 Dec., 1965], No. 53030/65. Heading B8B. A crane safety device comprises a first electric contact member 6 bearing sets of contacts 7, 8 secured at a join 5 to the free end of a Bourdon tube 2 connected to a device, such as is described in Specification 1,155,191, adapted to determine the total capsizing load exerted on the crane by its main jib and exerting hydraulic pressure in the tube 2. Corresponding sets of contacts 12, 13 on a second electrical contact member formed by a lever arm 14 face the contacts 7, 8. At one end the arm 14 is pivoted to base board 1 through a ball race bearing 15, and at the other pivotally linked through a link arm 16 and lock nut 17 to a massive weight 25 movable about a pivot 21 under gravity. Damper tanks 9, 27 are provided for the first contact member 6 and the weight 25, respectively. The device is so mounted on the crane body or chassis that tilting of the crane towards the jib (i.e. the root of the jib tending to go downwards) the weight 25 swings in the direction of arrow A reducing the gap between the sets of contacts 7, 8 and 12, 13 so that smaller hydraulic pressure is required in the tube 2 to close the gap and operate warning devices. Tilting of the crane in the opposite direction has,  until a very large value has been reached, no effect on the stability and movement of the weight 25 in that direction is stopped by stop 28, which also offers means for rendering the weight 25 inoperative until a certain degree of tilt has been achieved.

Abstract: 1,114,480. Refrigerating. SPACE CONDITIONING Inc. 26 Nov., 1966, No. 53045/66. Heading F4H. In an absorption refrigeration system having a first-effect generator 1 and a second-effect generator 8, a coil 30 for fluid to be heated is located in the second-effect generator. Heated solution from generator 1 passes to a separator 3 from which vapour passes to generator 8 and liquid passes via line 4, heat-exchanger 5 and line 4<SP>1</SP> to a coil 7 in generator 8. Vapour is condensed on coil 7 while generating additional vapour from the cooled solution passing through the coil, the resultant liquid-vapour mixture from coil 7 passing via line 9 to a further separator 10. From the latter, solution passes via line 12 and heat-exchanger 18 to the absorber 19 and vapour passes to a condenser 13 where it is condensed and mixed with condensate supplied via line 15 from generator 8; the combined condensate stream passes to the evaporator 17. Solution from the absorber returns to generator 1 via line 26 and heat-exchangers 18, 5. The degree of heating of the fluid, e.g. water, is regulated by varying the rate at which it is circulated through coil 30.
