Title: Improvements in or relating to tape-feeding apparatus
Inventor: HODGES ROBERT JAMES
IPC: G11B15/38
Filed: 1960-07-14
Abstract: 904,477. Magnetic tape-feeding apparatus. INTERNATIONAL COMPUTERS & TABULATORS Ltd. June 13, 1961 [July 14, 1960], No. 24620/60. Class 40 (2). In apparatus for controlling movement of a magnetic tape from spool to spool having negative air pressure means for engaging the tape with capstan or brake members, and e changeover valve causing positive air pressure to be applied in place of the negative pressure to free the tape, a constriction device is interposed between the said valve and the positive air pressure source whereby the initial positive pressure when the changeover valve is operated is casued to be temporarily higher than the following steady pressure. In the embodiment described and shown in the drawing, a negative pressure source 18 and a positive pressure source 22 are connected through changeover valves 8, 9, 10 to capstan 1, capstan 2, and brake members 6, 7, respectively. Inserted in the positive pressure conduits are constriction devices 23, 24, 25 which, while the valves 8, 9, 10 are closed to positive pressure, allow pressure between the said constriction devices and the said valves to be built up to that of the said source 22, so that when either of the valves are switched from negative to positive pressure the tape receives a temporary higher positive pressure so that the tape is instantly released from whichever of the capstans or the brakes are being rendered inoperative.

Abstract: 1,141,475. Image-forming photopolymerizable compositions. E. I. DU PONT DE NEMOURS & CO. 2 June, 1966 [3 June, 1965; 22 Oct., 1965], No. 24694/66. Heading C3P. [Also in Division G2] Image - forming photopolymerizable compositions comprise an organic polymeric dispersion binder containing a separate and dispersed phase comprising a non-gaseous ethylenically unsaturated compound (e.g. pentaerythritol triacrylate) boiling above 100‹ C. at atmospheric pressure and capable of forming a polymer by free-radical initiated, chain-propagating addition polymerization, and part of a photographic colour forming system, said part being incapable by itself of forming a colour image, the composition containing also a free radicalgenerating photo-initiator system. The initiator system may be a single compound or a combination comprising (a) a substance capable of being photochemically excited and (b) a free-radical producing agent capable of being initiated by (a) in its excited state; the system may be in the binder or dispersion medium, in the dispersed phase, in both phases, or at the phases' interface. The compositions are deposited on a support material and then exposed imagewise to actinic radiation. In the combination initiator system component (a) may be a cyanine, carbocyanine or merocyanine dye, a polynuclear quinone or a photo-reducible dye and component (b) may be carbon tetrabromide, triethanolamine, N-phenylglycine or 5,5-dimethyl- 1,3- cyclohexanedione; other examples are additionally disclosed. The dispersion binder may be gelatine or other natural or synthetic colloid binding agent; a synthetic polymer binder may also he added to the dispersed phase. The compositions are desirably stabilized against thermally initiated polymerization by inclusion of a suitable inhibitor. Other optional ingredients include plasticizers, e.g. diisobutyl phthalate; removable solvents, e.g. ethyl acetate; and surfactants. The compositions illustrated in the examples include polymeric colour-formers obtained by copolymerizing in solution in the presence of azobisisobutyronitrile (a) ethyl acrylate and 1 - hydroxy - N - (# - vinyloxyethyl) - 2 - naphthamide, (b) methyl methacrylate and 1-phenyl- 3 - methacrylamido - 5 - pyrazolone and (c) 2 - ethylhexyl acrylate and 2 - methoxy - 5 - methacrylamido-α-benzoylacetanilide.

Abstract: 1,235,694. Extrusion moulding machines. AKZO N.V. 23 May, 1968 [23 May, 1967], No. 24713/68. Heading B5A. An extrusion moulding machine comprises a pressure-responsive device 27 adjacent the extrusion orifice and a valve 4 having a baffle 8 situated in the flow path of plasticized material and drivingly coupled to a diaphragm 20, forces on the diaphragm due to the baffle being counteracted by compressed gas delivered via conduit 23, an electrically controlled pressurecontrol system coupled with device 27 regulating the supply of compressed gas so as to tend to keep the sensed pressure constant. Baffle 8 is coupled to diaphragm 20 via a silicone grease plug which coacts with a piston 18 in a cylinder 17. In operation, device 27 converts pressure values into electrical signals which are conveyed to electromagnetic switches 30, Fig. 2, the sensing of a sufficiently high pressure creating an electric signal sufficient to operate the switches and to change the feed of compressed gas to conduit 23 from path a to path b. Valves 35, 36 are set at different values, valve 36 allowing a lower pressure to exist above diaphragm 20 which results in a rise of piston 18 and such movement is transmitted to baffle 8 by the silicone grease plug in conduit 10 to thereby reduce the flow of material to the extrusion orifice. Additionally a valve oscillator 24 is provided which maintains a relative high frequency, e.g. 30-60 c.p.m., but low amplitude gas pressure change, e.g. 0À1-0À2 atmos. above diaphragm 20. Such oscillation is transmitted to baffle 8 whose responsivity is thereby increased. Downstream of the die orifice is affixed, via a heat insulating ring 13, a cooling and sizing device 14, 15, Fig. 1. A grease gun 25, 26 communicates with conduit 10. The extrusion of one or more bars and sheets is mentioned with, in the case of a sheet, the possible use of a plurality of baffles 8. Polyamide resin is mentioned as an example of extrudable material.

Abstract: 289,332. Jennings, I. C. Sept. 26, 1927. Pumping - machines; starting, facilitating.-The casing of a self priming centrifugal pump contains a separate chamber used as a storaae chamber for the liquid supplied to a liquid-ring pump which withdraws air from the centrifugal lamp. The impeller C of the centrifugal pump is enclosed in a casing a, b the part a being attached to the body A and the part b being attached to the water-head B. The body A carries the inlet 10 and outlet 13. The impeller shaft 14 passes through a stuffing-box 15 which has a flange 18 attached to the body A by bolts 19, the bolt holes in the flange being large enough to permit the shaft to be properly centred. Spring-pressed bearing rings 22, 23 are arranged between the ends of the impeller and the casing parts a, b thereby providing water seals on each side of the impeller. A partition 26, Fig. 3, is arranged between the water-head B and its inner part b to form a chamber D which communicates through the passage 29 with the rent pipe E. The liquid-ring pump F is carried by the waterhead B and has a port plate 310, Fig. 7, divided by a partition 32 to form inlet and outlet chambers 33, 34, proper passages and outlets being provided to obtain the necessary flow of liquid. The rotor 42 is keyed to the shaft 14 and rotates in an elliptical casing. A spring- pressed seal is employed to close the aperture in the plate B through which the shaft passes. When the motor is started the liquid-ring pump F sucks air through the passage 35, Fig. 7, and expels it through the passage 37 and the vent pipe E. This exhausts air from the centrifugal pump and water is drawn in to enable the pump to start. Any water delivered by the liquid-ring pump F will drop into the chamber D and will serve as a priming means for this pump when it is re-started. Specification 268,197 is referred to.
