Title: Improvements in detonating railway signals
IPC: B61L5/20
Filed: 1920-05-20
Abstract: 162,201. Wanklyn, F. L. May 20, 1920. Pyrotechnic devices. - Consists in the combination in a railway fog signal of a sheet-metal carrier b, adapted to lie flat on the rail, with a waterproof fibrous container f having its ends folded back upon themselves and superposed upon the carrier, a detonating cake c, and a flash-light powder d within the container, means g upon the carrier for clamping down the ends of the container in the folded-back position, and clips r for securing the device to the rail. The flash-light powder may consist of magnesium or a, mixture of potassium chlorate and magnesium; and a small charge c of red arsenic for producing a pungent odour may be added. The clips r extend from a transverse strip m which is secured to the carrier b by a rivet p and is made with two bents fitting into slots in the carrier b. When a wheel passes over and fires a detonator, these bents are crushed and the spring clips r lose their grip and allow the spent device to fall off the rail.

Title: Method of heat bonding panels of paperboard having a thermoplastic coating
IPC: B65B51/20
Filed: 1965-04-02
Abstract: 1,040,672. Sealing package closures. KLIKLOK CORPORATION. April 2, 1965 [Feb. 25, 1965], No. 13991/65. Heading B8C. [Also in Division B5] In a package sealing machine, two portions of a paperboard blank having a coating of thermoplastic material on opposite surfaces of at least these portions are bonded in overlapping position by discharging a stream of hot air having a discharge temperature higher than the char point of the paperboard, advancing the portions to be bonded through this stream to cause the stream to impinge on the side of the portions to be bonded and soften the coating thereon, the linear rate of speed of advance being in excess of that rate at which the coating on the opposite side would appreciably soften as a result of penetration of the applied heat through the board, and then, while the coating is still soft, bringing the two surfaces to which the stream was directly applied into bonding contact. Preferably, the two surfaces are brought in bonding contact within less time from the last moment of application of hot air than the total time of exposure to the hot air of any one surface point. In the machine shown for sealing cover side flaps of a filled box, filled boxes B1, B2, B3 emerge from under a box cover closing conveyer 11 and travel first on rails 12 and then on rollers 13. Lateral guides, e.g. plates 14, are provided. The boxes travel with the cover hinges 15 leading and cover side flaps 16, 17 flaring out slightly and are moved by an overhead endless conveyer comprising angular lugs 18, Fig. 5 (not shown), to engage the trailing walls of the boxes and hold the cover panels down. After sealing, an overhead chain conveyer 19, Fig. 5 (not shown), removes the boxes. Air discharge heads 20, 21, to pass between the flaps 16, 17 and the box body, having a horizontal cross-section similar to that of an airfoil and apertures 22, 23 in both vertical walls are supplied with hot air from a heat exchanger 29. Spacer fins 24 are provided on the heads 20, 21 to ensure uniform spacing of the box body and the flaps 16, 17 therefrom. Guide plates 25, 26 urge the flaps 16, 17 towards the fins 24. If the conveyers are stopped, a piston-and-cylinder type servomotor 34, Figs. 5 and 6 (both not shown), tilts the heat exchanger 29 clockwise to withdraw the heads 20, 21 downwardly. After heating, the flaps 16, 17 are pressed into engagement with the box body by rails 35, 36 and top rolls 37 (not shown), 38 ensure that the cover panel is properly folded down.

Abstract: 1459192 Apparatus for shaving leather TURNER MACHINERY Ltd 22 March 1974 [23 March 1973] 14032/73 Heading B4B A machine for shaving leather comprises a rotatable bladed cylinder 10 for operating onthe leather 30 which in use is held in contact with and drawn past the cylinder by feed means 16, 18 the rotation of the cylinder being such that the portion of the cylinder in contact with the leather moves in a direction opposite to the direction of the feed of the leather, and means actuable by an operator to change the speed of the feed means in order to vary the rate of feed of the leather past the cylinder. The feed means comprises a pair of rollers 16, 18 rotatably mounted on a cradle support movable by drive means from an open position in which a piece of leather can be draped over the roller 16, to a closed position in which both rollers are moved towards the cylinder in order to press the leather against the cylinder; the cylinder 16 is covered with rubber. In the closed position, the roller 16 co-operates with a roller 12 so that the piece of leather is moved outwardly toward the operator. The rollers 12, 16 are rotated by hydraulic motor 14, 20 which are supplied with hydraulic fluid by a pump 26 rotated by a motor 28. The cradle support for the rollers 16, 18 is operated by a foot pedal which is arranged to move the cradle between open and closed positions and also control the speed of rotation of the rollers 12, 16, e.g. in one position of the pedal the rollers rotate at a certain speed and in a second position the rollers rotate at half that speed. In modifications, (a) the speed change may be continuously variable over a given range of speeds and be effected by an electric motor, (b) two foot pedals may be used, one to start the machine and the other to control the speed, (c) the foot pedal may be replaced by a lever actuated by the hand or elbow and (d) the roller 18 may be rotated by contact with the roller 16 or driven by a gear or chain drive.

Abstract: 594,809. Vacuum coatings. MORGAN, W. L. June 11, 1945, No. 14716. Convention date, June 9, 1944. [Class 93] A pattern coating is produced on a support material by covering a portion of the surface of the material with a metallic stencil, magnetically mounting the stencil in contact with and in predetermined position upon the support material and applying in a vacuum a coating to the exposed part of the surface by deposition. Specified support materials are glass or other siliceous material, plastic, metal and paper and specified coating materials are metals, e.g., aluminium, magnesium fluoride and copper oxide. The coating may be deposited by cathodic sputtering or thermal evaporation. Referring to the drawings, a bell-like casing 11 having a surrounding flange 12 rests upon base 10, and has an exhaust pipe 13 for evacuating air from the casing. Inside the casing is mounted a workpiece supporting frame 14 comprising a back wall 15, side walls 16 and top and bottom walls 17. Guide strips 18 provide a means for supporting a removable workpiece 20. A plurality of horseshoe type permanent magnets 21 are held by bolts and screws 22 in position upon the inner face of the wall 15 and each magnet holds in position upon the workpiece a stencil 23. Alternatively electromagnets 26 supplied with current by cable 27 may be used. The casing is evacuated, filament 29 electrically heated and so thermally evaporates a suitable material previously applied to it. The particles thereof are thrown on to workpiece 20 to provide the coating

Abstract: 350,483. Automatic circuit-breakers. REYROLLE & CO., Ltd., A., Hebburn-on- Tyne, and MIRREY, J., Cairnsmore, Osbaldeston Gardens, Gosforth, Northumberland. March 11, 1930, No. 14775/31. Divided on 350,046. [Class 38 (v).] A circuit-breaker is arranged so that, when closed on to a short circuit, it is immediately tripped by the effect of the electromagnetic forces set up, thereby preventing damage to the operating means. A closing solenoid (not shown) acts on a guided shaft A to lift a contact-arm C which is retained in the closed position by an overset toggle GG<1> and a toggle BB<1>, which in turn is held set by an overset toggle EE<1> to which it is connected by a link E4 and lever E3E2. When the trip-coil F<1> is energized, it rotates the tripshaft F and breaks the toggle EE<1>, thus opening the switch, and the toggle BB<1> in collapsing breaks the toggle GG<1> by means of the finger B<3> and allows the shaft A to fall so that the toggles BB<1>, EE<1>, are reset. If the switch is closed on to a short circuit, the electromagnetic forces set up cause a pawl H<3> on the guided arm H to move downwards slightly and engage a projection F<2> on the shaft F and rotate it, thereby breaking the toggle EE<1> and opening the switch, so preventing damage to the closing solenoid.
