Title: Improvements relating to sliver guiding devices for use in the drawing or drafting of textile rovings
IPC: D01H7/92
Filed: 1937-07-07
Abstract: 487,727. Drawing - frames; sliver - guides. H. & B. AMERICAN MACHINE CO. July 7, 1937, No. 18925. Convention date, July 7, 1936. [Class 120 (i)] In drawing sliver or roving the material 50 is passed through condensers or guides 40, 41, Fig. 1, having guide grooves 53, Fig. 3, in the form of a helix which support the sliver throughout its passage from one set of draft rollers to the next, Fig. 2. The major portion of the helical groove is of partially circular cross-section and it serves to condense the sliver travelling therethrough and to impart a false twist. The mouth of the guide is flared and the sliver is folded therein. The guide members 40, 41 are provided in stages of no draft between the second and third and between the fourth and fifth pairs of rollers in the system comprising lower drawing rollers 12, 20 .. 24 and 14, and upper rollers 30 .. 36. Draft stages are provided following the first, third and fifth pairs of rollers, the sliver being condensed during the stages of no draft by the members 40, 41 which are mounted on traverse bars 43, 44. The guide members may be made of metal or of mouldable plastic materials and comprise a substantially cylindrical body 52 having an exterior helical groove 53 beginning at a point on the top surface of the body 52 extending partially around its circumference and terminating on the underside diametrically opposite its entrance. The top portion of the end face 55 is chamfered at 56 to provide clearance for the adjacent top roller so that the sliver may be delivered close to the nip of the succeeding pair of rollers.

Title: A device for audibly indicating whether an electric light is in or out
IPC: B60Q11/00
Filed: 1924-08-09
Abstract: 232,473. Shaw, A., and Fairer, F. Aug. 9, 1924. Electromagnetic interrupters; thermal switches. -In lamp-failure alarms of the kind employing a trembler as a signal, the warning circuit is made intermittent to diminish fouling of the contacts. So long as the lamp f<4> is unbroken, current flows from the battery f<5> through the switch f<3>, lamp f<4>, and magnet coil G, so that the armature A is permanently attracted and the trembler contacts B are separated. When the lamp filament is broken, however, current flows in the circuit which is shaded in Fig. 6. This circuit includes the resistance C controlling the thermascopic capsule D, switch E, trembler contacts B and magnet coil G. The resistance C, which consists of wire wound on mica and enclosed between outer layers of mica, thus becomes heated and by acting on the capsule D opens the switch E, whereupon current is cut off. The resistance C then cools again and the cycle of operations is repeated. The switch E comprises a vulcanite plunger e<2> adapted to be raised and lowered by the capsule D and carrying a nut which makes contact with the stationary casing of the switch.

Abstract: 1,173,366. Cine film cartridges. RICOH K. K. April 25, 1967 [April 25, 1966], No.18970/67. Heading G2E. A cine film cartridge for use with a projector comprises a spool 6 within a recess 4 of body 1, the film 5 being led via roller 11 to a slot in the cartridge defined by fixed surface 1b and by the surface 9a of a spring-loaded stop member 9 pivoting at 8 to grip the film end 5a until member 9 is depressed by pressure exerted on surface 9b through access channel 1d in the cartridge. When the cartridge is mounted on the projector, depression of spring-loaded arm (13) pivoted at (12) brings friction wheel (25) into driving engagement with the film and also shifts member 9 to open the slot, as in Fig.6 (not shown). The end (13a) of lever (13) is retained by step (15a) of a spring- loaded bell-crank (15). The film is then driven along arcuate film guide (32) until engaged by fasten rotating sprocket (18). Increasing film tension pivots arm (20) about the sprocket spindle (19) to depress pin (27) and rotate bell-crank (15) clock-wise to free the arm (13). Drive roller (25) is thus disengaged and the film is then sprocketdriven. After projection, the film is re-wound until the re-winding shaft is braked, at which time an electromagnet (21) is energized rotate bell-crank (17) and disengage stop (17b) from the stopped end of member 9. This member then pivots due to spring (10) and closes the cartridge slot to grip the film end. In a modification, member 9 may be depressed manually for retention by crank 17.

Abstract: 573,101. Presses for moulding and vulcanizing tyres &c. DUNLOP RUBBER CO., Ltd., and NORCROSS, T. Nov. 18, 1943, No. 19240. [Class 87 (ii)] The weight of the two movable press sections 1, 2, which are hinged at 5, 6, on the frame 7, is taken, at each side, by a bell-crank lever 9 which is pivoted at 11 to the lower section and carries two rollers 13 which rest on a curved track 14. The upper section is supported by a strut 8 which is pivoted at 10 thereto and at 12 to the lever 9. A pneumatic piston-rod 17 is connected to a support 15 which lies athwart the press and joins the two pairs of rollers 13. To open the press, the rod 17 is pulled to the left, whereby the rollers 13 run along the track 14 and lever 9 pivots about 11 ; the strut 8 and upper section are thereby raised and the lower section descends under its own weight. The linkage 8, 9 may hold the platens under considerable pressure, or bolts 23 may hold them together. To obtain a powerful opening effect, with great displacement of the linkage for a small separation of the platens, the two platens may initially fall together, the lower one falling slightly faster than the upper. The track 14 may be above the platens, the link 9 being then in tension, or may be straight. The linkage may be operated manually or by electric motor. The hinge 5 is vertically adjustable.

Title: Improvements in and relating to the manufacture of moulded artificial polymers
IPC: A61K6/083
Filed: 1951-08-17
Abstract: Moulded products are made from mixtures of (a) copolymers of vinyl chloride and vinyl acetate containing at least 75 per cent of vinyl chloride, and (b) acrylic and/or methacrylic acid esters, such as the methyl esters, and/or amides, alone or together with other polymerizable compounds such as styrene, by shaping the mixture, e.g. into films, granules, cords or ribbons, at a moderately increased temperature such as 40 DEG  C. in the absence of accelerating agents, and then polymerizing by the addition of accelerating agents such as benzoyl peroxide and redox and metal redox systems, such as a mixture of a peroxide with a tertiary amine, a sulphinic acid, or ferric stearate.  Also present in the polymerizable mixture may be a polymerization inhibitor such as hydroquinone, dyestuffs and/or plasticizers. Polymerization may be carried out by sprinkling accelerator on to the polymerizable mass, or by painting a solution of accelerator on to the walls of a mould in which polymerization is to be effected, followed by the application of heat or high frequency action.  The process may be applied to the manufacture of artificial teeth.  Specification 540,383 is referred to.
