Abstract: 766,185. Making electric incandescent lamps. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 23, 1953 [Sept 23, 1952], No. 26238/53. Class 39(2) A guide device to facilitate the loading of a lamp mount into the hollow mount pin of a head of a lamp sealing machine comprises a pair of segments 32, 33, Fig. 4, which, when brought together define a funnel, the segment 32 being mounted at the end of a primary spring-loaded pivoted arm 34 the normal position of which is limited by a stop 44, and the segment 33 being at the end of a secondary arm 39 pivotally mounted on the primary arm and held in substantially parallel relation to it by a biasing spring so that the segments are normally mated, their separation being effected by a portion of the sealing head engaging the secondary arm 39 in indexing the mount to the next work station. The primary arm 34, which is pivoted at 35 on a bracket 36, mounted on a pedestal 37, with a laterally offset portion 42 carying a pivot 41 for the secondary arm 39, and a torsion spring 43 at the pivot 35 of the primary arm 34 tends to hold the offset portion 42 against the stop 44. A weaker torsion spring 45 at the pivot of the secondary arm tends to close the segment 33 thereof against segment 32 of the primary arm. When a sealing head 2 is stopped at the mount-loading station B the funnel comprised by the segments is located directly above a mount pin. -The mount is next loaded into the guide, the inner surfaces of the funnel segments serving,to direct the leading-in wires of the mount into the aperture of the mount pin. After the loading of the mount the turret is indexed counter-clockwise whereby a thrust is exerted by the mount support against a depending skirt portion 46 provided on the segment 33 of the funnel which is thus moved away to permit passage of the mount pin and the mount carried by it. Specifications 232,953, [Class 39(ii)], 404,449 and 477,250 are referred to. Reference has been directed by the Comptroller to Specification 683,253.

Filed: 1923-10-23
Abstract: 227,908. British Research Association for the Woollen & Worsted Industries, and Bliss, H. J. W. Oct. 23, 1923. Winding-machines; roving and thread guides; rollers.-In a machine for winding yarn under tension, the yarn is admitted at a given rate to the admission side of the machine and is wound on to a cone at a greater rate on the receiving side of the machine, the yarn in consequence being stretched in a fixed proportion, the relation between the rate of feed and the rate of winding on being positively and exactly controlled in constant relation and being independent of the number of layers of yarn wound on top of one another on the receiving core. The yarn passes over a yarn guide 6 and round the smaller diameter of a two-diameter roller 3, Fig. 1, and thence to the core 1 upon which it is wound. The roller 3, which may be loaded to ensure sufficient frictional contact, rests upon and is driven by the core 1, thus ensuring a difference of speed between the smaller diameter of the roller 3 and the core 1, and a consequent stretching of the yarn. The bottom of the groove in the roller 3 may be sloped to accommodate more than one turn of yarn and the roller is traversed parallel to its axis to build the yarn upon the core 1. In a modification, the yarn passes round rollers 25, 3, 24, Fig. 5, to the core 1, the stretch being effected between the rollers 3, 24, and a scraper 21 being provided to direct loose ends of yarn on to the roller 24. In another modification, a belt 16, Fig. 4, is passed round pulleys 17, 18, carried on arms 19 pivoted at 20 and contacts with a roller 14 resting upon a roller 12, the thread passing from a point 23 round the system 16, 17, 14, 12 and being wound on a core 1 driven by a cylinder 10 at a greater surface speed than that of the roller 12.

Title: Production of thin-walled hollow articles from polyvinyl chloride pastes
Inventor: BROOKE ANDREW JULIUS
IPC: B29C41/14
Filed: 1955-09-16
Abstract: A paste used in forming a hollow thin-walled article by dipping (see Group V) is made of polyvinyl chloride which contains enough of a solvent or solvent mixture boiling below 90 DEG  C. to thin the paste to a viscosity which promotes the formation of a uniform film on the former on drainage.  In one example, the paste comprises 100 parts by weight of polyvinyl chloride, 70 parts of dioctyl sebacate, 30 parts of dioctyl phthalate, 3 parts of lead stearate, 3 parts of calcium stearate and 16 parts of carbon tetrachloride.  In another example, it comprises 100 parts of polyvinyl chloride, 65 parts of polyvinyl chloride, 65 parts of dioctyl sebacate, 7 parts of lead carbonate and 13 parts of carbon tetrachloride.ALSO:A hollow thin-walled article such as a surgeon's glove, is made by dipping a former into a paste made of polyvinyl chloride which contains enough of a solvent or solvent mixture boiling below 90 DEG C. to thin the paste to a viscosity which promotes the formation of a uniform film on the former on drainage.  The former is removed from the paste and allowed to drain.  The film left on the former is first heated sufficiently to gel then heated to a higher temperature to fuse the film; the primary heating being such that the draining and evaporation of the solvent are completed before the film temperature rises to 90 DEG C. The heating may be done in a series of drying ovens at increasing temperatures, the fusing occurring in the final one, or in a drying tunnel in which the temperature progressively rises from end to end. The former may be heated to 80 DEG C. before dipping and the solvent may be carbon tetrachloride or petroleum naphtha. The paste may contain a vinylidene polymer or copolymer. Examples, one containing dioctyl sebacate and lead carbonate, and another containing dioctyl sebacate, dioctyl phthalate, lead stearate, and calcium stearate, are given (see Group IV(a)).

IPC: G05F1/32
Filed: 1958-08-20
Abstract: 907,297. Transformer arrangements. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Aug. 20, 1959 [Aug. 20, 1958], No. 26746/58. Class 38 (4). An A.C. voltage control apparatus for regulating a voltage between upper and lower limits, comprises a tapped transformer 3, supplying a load 6 through a transductor winding 5 or a gating circuit D1-D4, R1, R2, connected to a tap T on the transformer. When the transformer terminal 4 is positive with respect to another terminal 7, and with the transductor non-conductive, a circulating current flows through R1, D1 hence the voltage at a point 8 is the same as that at tap T. The load is therefore supplied through R1, D4 at a voltage corresponding to that across T, 7. If the transductor is now set to conduct at a determined point in the half-cycle, the load voltage will increase to that across terminals 4, 7 for the remainder of the half-cycle. The transformer may alternatively be connected across the load or two tapped transformers may be employed. The transductor excitation may be controlled manually or arranged to maintain a constant output voltage automatically.

Title: Methods for lubricating the bearing system of a shaft rotatably journalled in a bearing housing and apparatus for performing the method
IPC: F16N7/38
Filed: 1971-04-19
Abstract: 1352433 Bearings SKF KUGELLAGERFABRIKEN GmbH 19 April 1971 [24 March 1970] 27080/71 Heading F2A The bearing system of a shaft rotatably journalled in a bearing housing is lubricated by pumping lubricant through an aperture in the housing so as to cover the bearings, and withdrawing the lubricant so as to leave a film of lubricant on the bearings. The lubricant is preferably a grease dispersed in a volatile liquid so that after the lubricant is withdrawn the liquid evaporates leaving a film of grease on the bearing. As illustrated, a bearing unit 10 for the drive-shaft of a spinning rotor is placed in a lubricating head 50 of a device in which lubricant is supplied to the head from a reservoir 34 by means of a piston 100. The bearing unit is held in the head by a bush 54 and the bearing cavity communicates with the chamber in the head to which lubricant is supplied. Lubricant is supplied to the head by means of a piston located in a cylinder 98 at the bottom of the reservoir in which ports 110, 112 are provided to allow lubricant to flow between the reservoir and cylinder. The piston is operated manually by means of a handle 104 causing lubricant to flow via ducts 116 and 74 to the head where it fills the bearing cavity of the unit. The lubricant is withdrawn from the bearing cavity by returning the piston, thereby leaving a film of lubricant on the bearing. The duct 74 is movable in the head and has a port 82 which communicates with the chamber in the head and a port 92 which when the duct is moved communicates with an opening in the reservoir 94. When the piston is operated with the ports 92, 94 open, lubricant is circulated and returned to the tank, thereby facilitating mixing of the lubricant.
