Title: Improvements in or relating to deck covering
Inventor: FISHER LESLIE AUSTIN
IPC: E04D3/32
Filed: 1967-11-24
Abstract: 1,244,163. Deck covering. SMITHS INDUSTRIES Ltd. 15 Nov., 1968 [24 Nov., 1967], No. 53472/67. Heading B5N. [Also in Divisions E1-E2] A method of producing a deck covering having water-resistant or weather-resistant properties comprising the steps of positioning a sheet having at least a layer of non-inflammable, non-vulcanized synthetic rubber material on the deck to be covered such that major portions of the deck are covered, fitting a moulded component of similar material over minor portions out of the plane of the deck so that at least a margin around the periphery of the component overlaps the sheet, and bonding the component to the sheet about the margin of interface between them. The sheet is secured to the deck, before fitting the moulded component, by adhesive and the component may be bonded to the sheet, formed with an asbestos backing, by adhesive, heat-welding or by ultrasonic welding. A hand tool, for use in the bonding processes, is also described and comprises a metal heating block secured to a pistol grip handle.

Title: Protective device for d.c. power transmission lines

Abstract: 1,120,459. Protective systems; converting. MOSKOVSKY ENERGETICHESKY INSTITUT. 17 Dec., 1965, No. 53594/65. Headings H2F and H2K. [Also in Division H3] In a high voltage D.C. protective arrangement, the A.C. energization of a winding 5 on a rectangular hysteresis loop magnetic core 4 by a D.C. current transformer 62 associated with the protected line, is normally rendered ineffective by core-saturation produced by a winding 6 connected through a Zener diode 22 and a choke 23 to a voltage divider 61 connected to the protected line. When a short circuit occurs, the drop in voltage of the D.C. line is such that the Zener diode 22 ceases to conduct and the core is no longer saturated and the A.C. in the winding 5 induces pulses in an output winding 9 under the control of a blocking oscillator circuit comprising a transistor 29 and windings 7 and 8. A winding 32 on the rectangular hysteresis loop core 31 of a magnetic counter is fed through a diode 30 with unidirectional pulses from the winding 9 and after a predetermined number of pulses the core 31 saturates. The resulting pulse from an output winding 36 causes a monostable vibrator 50 . . . 56 to change its state to energize a relay 60. The core 31 has a reset winding 33 controlled by a transistor 39, a correction winding 35 and a temperature compensating winding 34.

Abstract: 1277487 Metal spraying FLAME-SPRAY INDUSTRIES Inc 3 Nov 1969 [7 Nov 1968] 53717/69 Heading B2F [Also in Divisions C7 H2 and H5] An electric arc metallizing gun has two wires fed by a drive motor through wire guides in electrodes 15 and 16 to an arc zone at which an arc is formed between the ends of the wires, a jet 21 directed at the arc zone atomizing and spraying the melted metal of the wires, and the gun having means associated with it which automatically retracts the wires into the guides on deactivation of a control means for the drive motor. In the embodiment this drive motor is a DC shunt type, the control circuit for this being such that on deactivating the control means a shunt resistor is applied across the armature of the motor to provide braking, the connections to the armature are reversed and a capacitor discharges to provide the power to reverse the motor and retract the wires, the shunt resistor again providing braking on completion of this. The gun itself has the additional feature of a shield mounted against spacer lugs 85 and 86, there being access for atmospheric air between the shield and the rest of the discharge head of the gun, the gas from the nozzle 94 inducing this air into the space 93 such that it contains the spray of metal by providing an annular stream around it. The orientations of the guides are adjustable, so that the precise location of the arc can be selected.

The cold stretch may be at - 10 to - 40 C. for polypropylene or polyoxymethylene films, the hot-stretch at 130-150 C. and the heat setting at 130- 160 C. Other polymers are listed.

Abstract: 1279662 Log debarking apparatus MORBARK INDUSTRIES Inc 5 Nov 1969 [5 Nov 1968] 54239/69 Heading B5L Log debarking apparatus comprises a debarking member 5 rotatable about an axis 6 and having bark cutting members 8, and a pair of log-turning members 25, 53 having loggripping non-bark removing torque transmitting parts 27, 54. Each member 25, 53 is rotatable about its own axis which is inclined to the axis 6, and means are provided for rotating the members 25, 53 in directions b, c to spiral the log axially past the member 5, and for rotating the members 5 in a direction to oppose the rotation of the log imparted by members 25, 53, means are also provided for mounting the members 25, 53 for movement towards or away from the member 5, and means responsive to the latter movement to move the members 25, 53 to vary the relative inclination of their axes. In the apparatus described the members 25, 53 are mounted in carriers 24, 51 respectively which in turn are swivellably mounted on yokes 15, 37 respectively, each of which yokes is pivotally mounted on the machine frame 1. Link work is provided between the yokes 15, 37 which causes them to approach or move away from the member 5 together. Further link work is provided on each yoke which causes the carrier 24, 51 to swivel as the yokes move, the arrangement being such that the inclination of the axes of the turning members to the axis of the member 5 is increased as the members 25, 53 approach such member. This arrangement ensures that a small diameter log is fed past the member 5 more quickly than a larger one. The yokes are urged towards a log on the member 5 by a pneumatic piston and cylinder device interconnecting the yoke 15 and the frame 1. This allows logs of the same or decreasing diameter to pass through the apparatus, but if it is desired to insert a larger log a valve must be operated manually which causes the yoke 15 to be moved by the piston and cylinder device away from the member 5. The members 25, 53 are driven by fluid motors 32, 59 which are connected in the same power circuit via valves. The valves are such that they cause the motors to exert constant torque and thus adjust the peripheral speeds of the members 25, 53 to the peripheral speed of a log which may vary due to an irregular cross-section.
