Patent GB-1051486-A (GB)
IPC: B28B21/92
Abstract: 1,051,486. Wrapping pipes. WINN & COALES Ltd. April 8, 1965 [April 9, 1964], No. 14775/64. Heading F2P. A device for helically wrapping tape around a rotated pipe 38 or other elongated cylindrical member comprises carriers 11, 12 and 13, each holding a tape reel 17, which are moved along a track 14 extending lengthwise of the pipe, the arrangement being such that movement of the carrier. 11 at station A is initially delayed to produce annular windings about the pipe. Delaying means comprises an arm 19 pivoted to a member 18 which is slidably-mounted on the carrier 11 and fixed to a rod 27. Said rod passes through a support bracket 28 on the carrier 11 and is connected to the carrier 12. The arm 19 has a first projection 20, which engages between the rollers of a chain 21 driven from pipe-driving wheels 24, Fig. 3 (not shown), and a second projection 25, which runs in a guide track 26, Fig. 1 (not shown). The carrier 12 is connected by a rod 32 and a pawl arm 35 to the carrier 13. In operation, the main drive to the wheels 24 is engaged causing the pipe to rotate and the chain 21 to move. Arm 19 moves with the chain and causes member 18, rod 27 and hence carriers 12 and 13 to move axially of the pipe thereby helically wrapping tape about the pipe whilst carrier 11 remains stationary and annularly wraps the pipe. After one revolution of the pipe, the member 18 abuts the bracket 28 to axially move the carrier 11 so that the pipe is then helically wrapped from all three reels until a cam track 36 disengages pawl arm 35 from carrer 13. Tape is then applied annularly from carrier 13 and helically from carriers 11 and 12 until arm 19 is disengaged from the chain when the pin 25 rides up a sloping cam portion 40 of the guide track, the reel carriers and pipe then stopping. More or less than three carriers may be used and the chain 21 may be replaced by a lead screw. The reels 17 are loosely-mounted on their support spindles to permit the correct helix to be followed. Alternatively, the spindles may be set in a rotary mounting.

Abstract: 1,054,979. Making drill piping; improving physical properties. CONTINENTAL OIL CO. Sept. 21, 1964 [Nov. 4, 1963; Aug. 3, 1964], No. 38371/64. Headings B3A and B3V. [Also in Division E1] A method of increasing resistance to stresscorrosion of a metal comprises removing mechanically from the metal oxide-defective and decarburized surface layers and then inducing compressive stresses in the metal by surface working. Oil-well steel piping, casing, sucker rods and drill piping may be treated and articles of nickel, copper, aluminium, cobalt, titanium, zirconium, vanadium, iron, rhodium and platinum or alloys of these metals. Surface layers of 0À002-0À01 inch may be removed by milling or grinding, after which the metal is compressed to a depth of 0À001-0À02 inch or a greater depth by shotpeening, rolling, drawing or swaging. The surface may be treated at - 30‹ F. to 950‹ F., and inner and outer surfaces of tubular stock may be worked. Results obtained from fatiguetest specimens are included which were prepared by turning, removing the tool marks with sandpaper, furnace heat-treating for one hour, removing the scale with grit paper, and cold rolling locally with ¢-inch or 1-inch balls.

Abstract: 1,121,863. Ticket issuing. BELL PUNCH CO. Ltd. 24 Sept., 1965 [31 May, 1965], No. 23113/65. Heading G4T. In a ticket machine remote control system, e.g. for transport vehicles, comprising a master mechanism including an information indicator set by a master switch and one or more slave mechanisms including ticket machines having information printing means, if any of the printing means gets out of step with the master indicator, the error is indicated and may be corrected by the master mechanism. The system shown comprises master mechanism A, and four slave mechanisms of which only one, B, is shown. The master indicator comprises selector switches 2-4 having stepping contacts 6 which are set to indicate the tens and units of the journey stage number and the direction of the journey. Each slave printing means comprises three corresponding printing wheels (not shown) which are stepped by coils 27-29 respectively. The printing is effected when switch 30 is closed by insertion of a ticket; at the same time a relay 31 closes contacts 31/1 to cause a solenoid 32 to actuate a punch. The setting of the selector switches is determined by manually set master switches 7. Every time switches 7 are moved to a new setting, a start switch 19 is operated and causes pulsing of coils 23-25 to step associated switches 6 by the same amount. At the same time, relay coil 26 is pulsed to cause a corresponding number of pulses to be applied via contacts 26/1 to the coils 27-29. As the printing wheels are stepped, cams (not shown) rock the movable contacts of switches 8-10 between the pairs of fixed contacts which are connected to alternate contacts of the associated switches 2-4. Thus if any of the print wheels gets out of step with its associated selector switch, a relay 11, 12 or 13 is energized to cause the associated stepping coil to be connected via contacts 11/1, 12/1 or 13/1 to a correction line 60. A relay 34 is also energized through line 15, and causes error lamp 38, associated with slave B, to be lit. If the operator then presses a correction button (not shown), contacts 42, 43 are operated to switch off the error lamp and to energize relay 50 which causes a correction pulse to be sent via switch 55 and contacts 34/3 and 50/1 on line 60. If the correction pulse does not remove the out-ofstep condition, the faulty machine may be disconnected by opening switch 56. The other machines may then be operated by changing over switch 55 to a " manual " position, but any further out-of-step conditions have then to be corrected by direct manual adjustment of the faulty print wheels.

A fabric, preferably a woven fabric, of polyolefin ribbon yarns is subjected to a fibrillating means so that fibrils break-out on the surface of the ribbon yarns to produce a fabric having a hand and appearance similar to a fabric woven of natural fibres. Preferably, the polyolefin is high density polyethylene or isotactic polypropylene and the ribbon yarns are oriented longitudinally. The fibrillating means may comprise grit impingement, e.g. compressed air sand blasting or pellet blasting, abrading, e.g. with a rotary wire wheel or a grindstone, or needling with barbed needles, e.g. with reciprocating needles or a rotating needle roll. The needles may be constructed as shown in Fig. 4a, 4b or 4c. The fabric may be heat set before or after fibrillation. Fibrillated fabrics of this invention may be used as primary and secondary backings PB, SB, respectively, in a tufted pile carpet fabric, Fig. 3.

Abstract: 1,265,896. Semi-conductor devices. TEXAS INSTRUMENTS Inc. 8 May, 1969 [17 May, 1968], No. 23563/69. Heading H1K. The corrosion resistance of a W layer in contact with a semi-conductor device is increased by incorporating in the W a significant amount of a more resistant metal such as Ti, Ta, Cr, Zr, Hf or Si. The modified W layer may be in direct contact with the semi-conductor surface and may be covered with a highly conductive metal such as Au, Al or Pt may, however, be flashed on to the semi-conductor surface prior to application of the modified W layer, in the latter case to form the basis of a sintered platinum silicide layer on a Si device. Fig. 12 shows the application of the invention to multi-layer interconnections on a Si integrated circuit. The lower level of interconnections, which contacts the semi-conductor body 70 through openings in an insulating layer 113, comprises a layer 116 of W or W/Ti, a layer 117 of Au or Cu and a layer 118 of W. An insulating layer 119, e.g. of silicon oxide or nitride, aluminium oxide or an organic material, covers the lower interconnection level, and an upper interconnection level makes contact with selected areas of the lower level through openings in the layer 119. The upper level comprises a layer 120 of corrosion-resistant W/Ti and a final layer 121 of Au. The corrosionresistant layer may be applied by r.f. or triode sputtering.
