Abstract: 655,000. Supply systems for space discharge lamps. GENERAL ELECTRIC CO., Ltd., and WILLOUGHBY, A. H. Oct. 11, 1948, No. 26464. [Class 38 (iv)] An electric discharge device particularly a high pressure lamp 5 has a starting circuit independent of the operating circuit and which applies to the lamp a plurality of pulses in rapid succession substantially in synchronism with the peak values of each half cycle of the A.C. supply voltage. Preferably the means producing the pulses is rendered inoperative when the lamp discharge is fully maintained. The pulses are generated by a transformer having its secondary winding 14 connected across the lamp through a spark gap 9 and its primary winding 15 energized either direct from the A.C. source 1, 2 (Fig. 1, not shown), or from a D.C. source 16 through the contacts 17 of a relay 19 responsive to the alternations of the A.C. source. In the former arrangement a peaky transformer is employed and in the latter a high voltage transformer. To render the pulse generator inoperative when the lamp discharge is fully maintained a relay 7 responsive to the lamp discharge current opens contacts 13. A high frequency choke 8 and condenser 81 are included in the lamp-operating circuit to prevent the pulses being fed back into the supply mains. The spark gap may be provided with a de-ionising air blast. According to the Provisional Specification the relay coil 19 may be connected to the D.C. source through the secondary winding of a transformer having its primary connected across the A.C. source, thereby providing one pulse every cycle of the A.C. supply.

Title: Improvements in apparatus for pulping vegetable foods
Inventor: GARRICK PETER
IPC: A23L19/00
Filed: 1964-06-26
Abstract: 1,099,934. Steam-cooking apparatus. BRITISH FOOD MANUFACTURING INDUSTRIES RESEARCH ASSOCIATION. Sept. 24, 1965 [June 26, 1964], No. 26574/64. Heading A4D. In a flow process for the production of fruit pulp by steam cooking, the rate of progress of the fruit downwardly through an upright cooking chamber 10, and thus the time of cooking, is made self-regulating by providing a constant resistance to flow. The resistance may take the form of a side passage 14 and a weir 26 and when the height of weir 26 has been correctly adjusted, uncooked fruit pulp of insufficient plasticity is slowed down, on entering the side passage 14, and becomes adequately cooked. Washed fruit is delivered to hopper 20 by an elevator and periodically admitted to chamber 10 by opening doors 22. Live steam enters the chamber through holes 16 and perforations in pipe 18. The passage 14 may contain a stirrer and be provided with a cold water inlet. In another form (Fig. 2, not shown), the cooking chamber 28 is split and the lower half displaced horizontally so as to provide a further flow retardation passage 14 for the partially cooked fruit.

Title: Improvements in or relating to tool carrying chains for use on coal cutters and the like
IPC: E21C25/36
Filed: 1953-09-28
Abstract: 766,438. Chains; ball joints. PROCTOR, S. E., and HOY & CO., Ltd., A. Sept. 15, 1954 [Sept. 28, 1953], No. 26642/53. Classes 24 and 65 (2). In a tool-carrying chain comprising links connected by ball-and-socket joints, a part of the socket is removable and is secured in the link body by a bayonet type joint, means being provided to prevent rotation of the removable socket-part after assembly. Fig. 1 shows a chain of the type described in Specification 626,080 comprising links having a body portion 21 consisting of two side walls joined at one end by a curved cross-wall 22 constituting the outer portion of the socket, and at the other end by a block 23 which carries the cutter tools and a ball 25 having a stem 24 which is secured in the blade 23 by a rivet 36. The socket portion has a bore 26 in which is fitted a two-part removable liner 27, 28. Liner part 28 has a stem 29 which seats in a smaller extension of the bore 26. Liner part 27 has a deep groove 129 milled across it, the bottom 30 of the groove extending at an angle to the axis of the liner, and the part is formed with two external projections 31 (Fig. 3). The link is machined away at 33 sufficiently to permit the liner to be introduced into the bore 26 with the projections 31 extending fore-and-aft of the link and then rotated through a right angle so that the projections 31 engage a groove 32 extending around the interior of the bore 26. Reverse rotation is prevented by a cotter-pin 35 held in place by riveting over its end. In an alternative construction, Figs. 8 and 9, the bore extends through the link horizontally from side to side and has a circumferential groove 54 near each end, the ends being formed with four notches 65, 66, 67 and 68 to pass four projections provided on each of two liners 42 and 43 which are inserted from opposite ends of the bore and then rotated through one eighth of a turn so that the projections engage in the grooves 54. The liners are locked in position by a metal strip 64 which is passed through a recess machined through the link in line with the notches 68 and the ends bent into grooves provided across the ends of the liners 42 and 43. In a modified form of this construction, the central portion of the bore is made larger than the end portions which are notched out at four places. Each liner is provided with four recesses at its end, and the liners are inserted through the groove in the top of the link into the bore and are then moved outwardly until they fit into the notches in the ends of the bore, in which position sufficient space is left between the liners to allow entry of the ball. The liners are then moved together, rotated through an eighth of a turn and locked in position by a metal strip. A further construction is described in which the invention is applied to the type of chain described in Specification 699,636. Specifications 703,652 and 715,776 also are referred to in the Provisional Specification.

Title: Improvements in or relating to the manufacture of hose or tubing composed of rubber or similar material
IPC: B29C35/00
Filed: 1934-09-20
Abstract: In the process for moulding and heat treating tubes of indiarubber, synthetic resins, and the like as described in Specification 425,281, wherein the tube is distended by internal pressure against the walls of a cylindrical mould, a positive thrust is applied progressively along the interior of the tube to ensure uniform contact with the walls of the mould, and to eliminate inequalities in the wall thickness.  This is done by forcing a calibreing member, generally of frusto-conical form, and of slightly greater diameter than the internal diameter of the tube, along the tube, either manually or by compressed air, or a combination of these.  This member on reaching the distant end may act as a stopper for the compressed fluid during the heat treatment.  The process is applicable to the production of short or long lengths.  In the latter case, the operation proceeds in stages, the calibreing member being forced down the mould progressively by compressed fluid as the tube is advanced through the mould.
