Title: Process for preparing road surfacing products
IPC: C08L95/00
Filed: 1937-12-13
Abstract: The process described in the parent Specification for making a road-surfacing composition consisting essentially of a bituminous emulsion containing a substantial proportion of powdered coal as a filler, is modified by incorporating the filler in the form of an aqueous dispersion, in the presence of a stabilizer comprising carragheen, carob bean, gelatine or the like.  The stabilizer may be added to the dispersion of filler, to the bituminous emulsion, or to both.  In an example, an emulsion containing 35 per cent of bitumen, 15 per cent of filler, and 50 per cent of water is prepared by mixing 58 parts of a bituminous emulsion containing 60 parts of bitumen to 40 of water, and 42 parts of a filler dispersion containing 36 parts of filler to 64 parts of water, about 1,3 per cent of carragheen having been added to the water. Suitable emulsifying agents referred to are soaps, e.g. oleates, resinates, naphthenates, stearates or palmitates; sulphite lyes or black liquor from paper mills.ALSO:The process described in the parent Specification for making a road-surfacing composition consisting essentially of a bituminous emulsion containing a substantial proportion of powdered coal as a filler, is modified by incorporating the filler in the form of an aqueous dispersion, in the presence of a stabilizer comprising carragheen, carob bean, gelatine or the like.

Title: Slot wedge for dynamo-electric machines
IPC: H02K3/487
Filed: 1955-12-02
Abstract: 771,109. Slot wedges. GENERAL ELECTRIC CO. Dec. 2, 1955 [Dec. 7, 1954], No. 34575/55. Drawings to Specification. Class 35. Slot wedges of uniform cross-section for use in dynamo-electric machines are formed by passing a roving of glass fibre or other continuous fibrous insulating material through a tank containing a suitable solventless heat polymerizable liquid resin in which the fibres are maintained until they are thoroughly wetted. The liquid resin may consist of substantially equal parts by weight of diethylene glycol maleate and diallyl phthalate to which are added a suitable polymerization catalyst such as benzoyl peroxide. The wetted material then enters a die through a tapered aperture wherein it is cooled to prevent premature hardening. The remainder of the die is heated so that the material is cured in the die at the same time that it is receiving its final shape. Subsequent to emerging from the die, the product may be further heated to complete the curing process, and, when this is finished, the insulating fibres and the solventless polyester will have combined to form a substantially homogeneous strip which is cut into suitable lengths to form the individual wedges.

Title: Slub yarn and process for the production thereof
Inventor: MYERS NEIL OSCAR
IPC: D02G1/16
Filed: 1967-07-28
Abstract: 1,144,545. Producing slub yarn: slub yarn. E. I. DU PONT DE NEMOURS & CO. 28 July, 1967 [29 July, 1966], No. 34750/67. Headings D1F and D1W. A process for the production of slub yarn using a high velocity stream of compressible fluid to provide turbulent flow through a chamber comprises continuously over-feeding multifilament yarn to the yarn entrance 26 of a jet device 14, withdrawing the yarn countercurrently to the jet stream, jetting compressible fluid continuously to maintain the travelling yarn under tension with a loop extending into a chamber 17, and forming slubs of random size and frequency along the yarn by turbulence of the fluid. The yarn so produced is preferably subsequently treated with a slub-consolidation jet to increase the filament entanglement. A carrier yarn may be combined with the slub yarn at the slubconsolidation jet. The yarn may be overfed by 3%-33%, comparing speeds of feed and withdrawal, and preferably overfed by 5%- 20%. In the production of the slub yarn a carrier yarn may be fed countercurrently through the jet device to be combined with the slub yarn and removed therewith. In a preferred form of the process, continuous multifilament yarn is fed via a finish coating roller and feed rolls to the jet device. The yarn passes adjacent the open end of yarn entrance 26. Fluid is supplied under pressure to the annular chamber 13 by a pipe 16, and leaves the device 14 via chamber 17. Turbulence is created in the region 30 surrounding the inner end of yarn entrance 26. The yarn over-fed to the yarn entrance 26 is thus drawn into the chamber 17 in the form of a loop and the turbulence creates a slub. The slub yarn is then withdrawn through the yarn entrance 26. In an alternative form of jet device, the yarn passes through the device in a channel at right angles to the fluid flow. A vertical swirling motion may be produced in the slub producing chambers by supplying fluid tangentially to the chamber. The yarn produced is characterised by sections of uniform base yarn and at least 200 slubs/1000 yards of random size and spacing; at least 50% of the slubs having a denier ratio (denier of slub to denier of initial yarn) less than 3 and at least 1.1, the remainder having a denier ratio of at least 3 and containing at least one yarn loop entangled within the yarn mass: at least 70% of the slubs being 0.1 inch-1 inch in length, the remainder being of greater length and including at least one slub having a length of at least 10 times the average slub length.

IPC: H01H73/56
Filed: 1959-10-20
Abstract: 901,804. Automatic circuit-breakers; switches held set and freed mechanically. WOOD ELECTRIC CORPORATION. Oct. 20, 1959, No. 35489/59. Class 38 (5). A trip-free circuit-breaker comprises fixed contacts 8, 10, engageable by contacts secured to a bridging bar 12 mounted on a slide 14 movable in guides formed in the shell 2 and its cover, Fig. 3 (not shown). A compression spring 42 normally maintains the contacts open and moves a cam 33, carried by the slide 14, towards another cam 32 pivoted at 38, a tension spring 34 urging cam 32 anti-clockwise to assist spring 42 to bring the two cams together. Depression of a button 24 and a link 23 pivoted to the latter at 28 causes rolls 22 to separate cams 32, 33 until the former engages a latch plate 48 carried by a bimetal 20, whereupon the rolls 22 actuate cam 33 to close the contacts until the button 24 is withdrawn. A moderate overload produces a delayed trip by deflecting bimetal 20 to the right to release the cam 32 and allow the spring 42 to open the contacts and, subsequently assisted by the spring 34, to restore members 23, 24, 32, 33 to normal. A heavy overload causes an instantaneous trip by deflecting an armature 50 mounted on the bimetal 20 towards a U-shaped magnetic core 58 partially enclosing a terminal plate 46, Fig. 4 (not shown), and mounted together with member 46 on the shell 2 by a screw 54, another screw 52 allowing adjustment of the bimetal 20. Undue rotation of the link 23 is prevented by engagement of a stud 30 with the button end.
