Title: Improvements in the electrical operations relating to line contactors used with tramway point turners, railway signals, and other like mechanism
IPC: B61L11/00
Filed: 1932-02-13
Abstract: 381,065. Actuating railway points and signals from vehicles. QUILLIAM, S. T., 4, Longford Road, Stretford, near Manchester. Feb. 13, 1932, No. 4316. [Classes 104 (i), 104 (iii), and 105.] Apparatus for the control of points or signals by the passage of a bow or trolley collector over a conductor-line contactor, such as is described in Specification 273,633, [Class 104 (i), Railway and tramway crossings &c.], is provided with a delayaction relay and an are-blow-out coil to break the circuit to the points or signal control apparatus if the vehicle should remain with its collector on the contactor. Fig. 3 shows the arrangement when a bow collector is used, the contactor ramps 10, 11, 12, being sufficiently spaced to obviate the necessity for the coil r, Fig. 1 (not shown), which is provided when a trolley wheel collector is used since the contactor ramps must be located close together so as to be engaged by the trolley wheel flanges. When the bow collector engages the contactor ramps 11, 12 the series relay m is energized if the vehicle is taking current and the armature n accordingly selects the winding b for operating the points ; the current flows to this winding b when the collector engages ramp 10 but only for a limited time as the delay-action relay 3 is simultaneously energized and in due course ' opens the contact t by its plunger 4 engaging an arm 5. The coil 6 acts as a magnetic blowout for any arcing at the contact t. If the vehicle is not taking current the armature n selects the winding c for operating the points to the other position.

Title: Improvements in or relating to apparatus for sealing packages
IPC: B65B51/06
Filed: 1954-02-15
Abstract: 746,624. Labelling machines. CHRISTENSSON, O. W. Feb. 15, 1954 [Sept. 23, 1953], No. 4365/54. Class 73 In a machine for sealing ends of rectangular packages, each having end closure flaps, the packages (not shown), supported on one end, are moved continuously on a conveyer 10 and a predetermined length of sealing strip 11 is fed by rollers 13, 14 so that its leading part contacts a leading vertical side of the package, brushes 19<SP>1</SP>, 35 applying the strip to the package so that the leading part is secured to the leading vertical side. a middle part of the strip is applied to the horizontal end to seal the slot between the outer closing flaps and a trailing end part of the strip is secured to the trailing vertical side of the package. In the construction shown the leading face of a package on a conveyer 10 meets a sealing strip 11 which has been fed upwards by a roller 13 and pressure roller 14, and has passed through rollers 17, 18 for moistening it. The leading part 20 of the strip is smoothed over the leading face by a brush 19<SP>1</SP> which is mounted on a pivoted arm 24' and driven by gearing 23, 25<SP>1</SP>, the gear 23 being mounted on a shaft 22 about which the arm pivots. The arm is pressed upwards by a spring, but as the packet advances it is swung clockwise to the position indicated at 19<SP>11</SP> smoothing the strip over the leading face during this movement. At position 19" the brush smooths the strip over the closing flaps on the bottom face of the package. At a suitable moment the strip is severed by a cutter 16, and the trailing edge of the strip is subsequently smoothed over the rear face of the package by a brush 35 mounted and driven in a similar manner to the brush 19<SP>1</SP>. Such smoothing is effected when the arm 36, upon which the brush is mounted, moves clockwise under spring action after being released by a cam-actuated lever 43 pivoted on the shaft 22. The movements of lever 43, of the cutter 16, and of presser roller 14 are controlled by cams 48, 29 and 60 on a hub 58 which is selectively coupled to a hub 57 on a driving shaft 28. The coupling is effected by a spring-pressed ball 59 which becomes disengaged, to stop the cams from functioning, when a pin 56 on cam 48 encounters an arm of a bell-crank lever 54. Such disengagement, however, occurs only when a vacant space occurs on the conveyer; under normal conditions each package closes a switch 51 to energize a solenoid 52 which serves to move the lever 54 to a position in which a groove 55 therein will allow free passage of the pin 56.

Filed: 1974-01-31
Abstract: 1426973 Flying heads INTERNATIONAL BUSINESS MACHINES CORP 31 Jan 1974 [1 March 1973] 04508/74 Heading G5R A flying head magnetic transducer assembly has a transducing gap 50 defined between a wound magnetic core piece 40 and an elongate magnetic slider body 20 supporting the piece 40, parallel spaced apart rails 21, 22 extending substantially the whole length of the body 20 on the underside thereof to present air-bearing lower surfaces by means of which the assembly is supported in use above the surface of a moving magnetic medium. Outer rails 21, 22 are spaced from a central rail 30 by slots 35, 36 providing bleed paths for undesired air from rails 21, 22. The lower surfaces 25, 26, 32 of rails 21, 22, 30 are flat and coplanar and continue as upwardly inclined surfaces 23, 24, 31 extending to the leading end of body 20, the core piece being attached to the trailing end of body 20 by adhesive 45, e.g. glass, located at the region of gap 50, a back gap 46 also being formed between body 20 and core 40. The width 34 of the lower surface of rail 30 is much less than that of rails 21, 22 which therefore provide substantially all of the air bearing effect. The assembly is supported so that it tends to resume an equilibrium position when disturbed, the gap 50 being located at the roll and pitch axes of the assembly and therefore flying at a constant height of several microinches. The body 20 may have a length of 0À25 inches and a total width of 0À15 inches, the assembly weighing 0À25 grams and being suspended from a thin piece of stainless steel which provides stiffness parallel to the recording medium, the suspension 52 including a load beam 53 applying a downward load of less than 20 grams within the notched region 51 preferably but not necessarily at the centre of gravity of the slider body 20. The body 20 and core 40 may be made of ferrite.

Abstract: 883,056. Coated glass fabrics. UNION CARBIDE CORPORATION. Feb. 14, 1958, No. 4849/58. Class 140. [Also in Groups II, XXIII and XXXVI] Coloured glass fabrics are produced by coating the fibres thereof by decomposition of a heat decomposable gaseous aluminium compound to form a layer thereon of aluminium metal, anodizing the aluminium, dyeing the anodized aluminium, and sealing the dyed coating by hydrolysis of the anodized aluminium, all whilst maintaining the fibres flexible. The glass fibres may be heated prior to contacting with the heat decomposable gaseous aluminium compound, the contact occurring at atmospheric pressure when the aluminium compound is of formula Al(R) 3  wherein R represents any alkyl radical of low molecular weight preferably below six carbon atoms, e.g. methyl, ethyl or propyl radicals, and securing under reduced pressure conditions when the aluminium compound is of formula Al(R) 3  wherein R is a benzyl or phenyl radical. The aluminium may be anodized in an acid bath, e.g. sulphuric or chromic acid bath, to provide a layer of aluminium oxide thereon and the resultant fibres washed free of acid. The sealing of the dyed coating may be effected by subjecting the fibres to a hot aqueous treatment, e.g. in a nickel acetate solution, to hydrate the aluminium oxide. Specified dyes are malachite green, methyl violet, alizarine dyes, thioflavine and para-red. As shown, glass fibre rovings 3 pass through oven 5 operating at 300‹ to 600‹ F. to remove lubricant, which may be present in the rovings, prior to entry into heating chamber 7 wherein the rovings are heated to approximately 525‹ to 550‹ F. and into which inert gas, e.g. nitrogen or carbon dioxide, is passed via conduit 21 to seal the interior of the passageway from the atmosphere. Gaseous aluminium compound, e.g. at 325‹ to 350‹ F. flows from inlet 29 and decomposes to form an aluminium coating on the heated rovings in coating chamber 27, the organic gaseous fragments being withdrawn through outlet 31. The coated rovings pass over metal pulleys 37 in lead-lined anodizing tank 35, the pulleys and lining functioning as anode and cathode respectively to convert the aluminium into aluminium oxide. From tank 35, the anodizing material is washed free of acid in tank 43 and in tower 49 and is dyed in tank 53 prior to passage through bath 57 to seal the dyed coating.
