Patent GB-865465-A (GB)
Title: Making moulded articles
IPC: D21J7/00
Filed: 1958-03-10
Abstract: Chopped multifilament strands of separable glass fibres and water are mixed with agitation to form a slurry, the extent of the agitation being controlled so as to maintain the integrity of the multi-filament strands, the slurry then being urged against a porous shaping element.  The control of the degree of agitation may be effected by delivering the slurry to the mould surface by direct gravity feed.  Because of the low self-adherence of glass strands, cellulose fibres, e.g. bleached or unbleached Kraft pulp, alpha cellulose fibres or sisal fibres may be incorporated into the slurry. Other fibres e.g. cellulose acetate, may also be added alone or in combination with the cellulose fibres.  The weight ratio of glass fibres to cellulose fibres is preferably within the range 3 : 2 to 7 : 3.  These preforms may be moulded in combination with polyester resins (e.g. with a conventional mixture of styrene, propylene glycol maleate phthalate, and a curing catalyst) or with other resins such as epoxy or phenol-formaldehyde resins.

Title: Crimpable filaments of synthetic linear polymers and process for making them
IPC: D01D5/30
Filed: 1965-02-22
Abstract: 1,087,939. Artificial filaments having crimp potential. FARBWERKE HOECHST A.G. Feb. 22, 1965 [Feb. 21, 1964], No. 7628/65. Heading B5B. Three-dimensionally crimpable filaments are made by melt spinning a homogeneous melt of linear polymers, the process comprising producing two separate streams of the homogeneous melt, the ratio of the gravimetric rate of flow of the streams being within the range of 1: 1À5 to 1: 4, extruding them together without mixing them through the or each extrusion orifice of a spinneret, withdrawing the thus formed filament from the spinneret, cooling and thereby solidifying the filament and cold drawing the solidified filament at a draw ratio of 3 to 4. The linear polymer may be a polyester, a polyamide or a polyalkylene. The two separate streams of melt having different gravimetric rates of flow may be produced and supplied to the spinning head by means of two separate extruders each communicating with the spinning head through its own separate duct and supplying the spinning head at a gravimetric rate of flow differing from that supplied by the other extruder. The separate streams of melt may be joined in the spinneret immediately before leaving the spinneret extrusion orifice or in the inlet to the extrusion orifice. The two separate streams of melt may be fed to a spinneret having several extrusion orifices in such a manner that each stream is uniformly distributed over all the orifices and the subdivided separate streams are united again in each orifice just before the united streams leave the orifices in the form of filaments. The solidified drawn filaments may be maintained for 1 to 5 minutes at a temperature within the range of 120‹ to 180‹ C. or treated for this period with boiling water or saturated steam at atmospheric pressure whereby the filaments acquire a three-dimensional crimp of very high retentivity. Staple fibres obtained from the filaments may be crimped in the same manner.

Title: Improvements in or relating to electric elevator systems
IPC: B66B1/18
Filed: 1926-03-19
Abstract: 252,329. Waygood-Otis, Ltd., (Assignees of Lindquist, D. L., Dunn, E. L., and Larson, D. C.). May 21, 1925, [Convention date]. Electric-motor actuation. - The motor generator set of a lift is stopped when a given time has elapsed after the last call has been answered by a time switch. A motor 392 drives a vertical shaft which is connected by worm gears 402, 405 to a horizontal shaft 406. Worm gears 410, 411 connect the shaft 406 to a vertical shaft 412, on which is pivoted a bell-crank lever 417. An idler gear 421 is rotatably mounted on one arm of the lever 417, and is driven by the gear 422 on the shaft 412. The gear 421 is engaged with a gear 423 by a clutch magnet 424 acting through a hellcrank lever 427 and link 437. The gear 423 is mounted on a pin 441 secured in plate 400, and is connected thereto by a torsion spring 442. A series of apertures 443 arranged in a circle about the pin 441 are threaded to receive either a stop pin 444 or a trip pin 445, the stop pin being screwed in from the lower face, and the trip pin from the top. The apertures 443 are so positioned that with the speed reduction obtained, each successive aperture represents an additional half minute in the time interval to be obtained. The trip pin 445, Fig. 21, is arranged to engage, after an interval of four minutes, an insulating block 446 secured beneath the end of an arm 447 pivoted on a pin 448 mounted in the bracket 450. A torsion spring 453 connects the arm and bracket. A lever 456 carrying a movable contact 457 is pivoted in the bracket 450 and pivotally supports an arm 466, the upper end of which is provided with lugs for engaging a projection 470 to cause the actuation of the switch. A tension spring 471 connects the upper end of the arm 466, and a lug on the outer end of the arm 447. When the pin 445 engages the block 446, the outer end of the arm 447 moves to the right, Fig. 21, thereby causing the lower end of the spring 471 to approach the centre line of arm 466. Meanwhile the switch contacts 457, 463 are kept in engagement to eliminate chattering and burning. As the lug on arm 447 passes the centre line of arm 466, the spring causes clockwise movement of the latter arm, and the lug on its upper end strikes the projection 470 a hammer blow, thereby causing quick separation of the contacts. The motor 392 and magnet coil 483 are now deenergized. The plunger of the magnet falls and strikes the lever 427 a hammer blow, thus disengaging the idler gear 421. The gear 423 is returned to normal position by the spring 442. As soon as the pin 445 moves away, the spring 453 overcomes the spring 471, and returns the arm 466 to its initial position. Specification 247,145 is referred to.
