IPC: F16L59/20
Filed: 1970-01-23
Abstract: 1291135 Producing insulated pipes; pipe couplings SOLVE SYSTEMROR AB 23 Jan 1970 3402/70 Headings F2G and F2P A method of manufacturing insulated pipes includes locating a core 6 within a jacket 5 having ends 3, 4 and moving the jacket 5 and core 6 relative to a nozzle at the end of a tube 7 supplying a foaming agent which fills the annular space between the core 6 and jacket 5 with a foam layer. The core 6 may then be removed and replaced with a pipe of smaller external diameter or a hollow core is used which contains a pipe whose external diameter is smaller than the internal diameter of the core. In the apparatus shown in Fig. 1 the core 6 and jacket 5 are moved in the direction A by a conveyer 1 while a second core 6a and jacket 5a are brought up for subsequent filling and reversal on the conveyer 2. Multiple passageways may be formed in the foam layer by the use of several cores. The jacket 5 may be of thermoplastic, e.g. P.V.C. and may have embedded glass fibres, the solid foam is polyurethane and an air gap between the pipe and the core or foam due to the smaller diameter of the pipe permits the easy insertion of helically seam welded metal pipes. As shown in Fig. 2 the culverts 5 may be coupled by means of a sleeve 14, rubber sealing rings 15; 16, rubber discs 17, 18 and polyurethane enclosures 12, 13. The inner pipe is welded at S.

Filed: 1917-03-08
Abstract: 112,694. Somerville, W. March 8, 1917. Machines for making.-Relates to wire rope or cable making machines of the kind in which reels of strand wire are carried by cradles that are hung so as to remain stationary within revolving cages, the wires from all the reels being carried along the entire line of cages and passed through a die at the end of the machine. According to the invention, means are provided to stop the machine when a strand breaks, and to re-wind the slack upon the reels if it is necessary to reverse the machine to bring the break into an accessible position. The reels 29 of strand wire are mounted in cradles 20 hung in cages formed by wheels 18 connected by rods 19, the cages being revolved by friction wheels 17 carried by a shaft 16, Each strand passes through an opening 56 in the axle of the next wheel 18, over a guide-pulley 56a, through openings near the periphery of the succeeding wheels 18, through a rotary hub 21 carrying a twisting-die 22, and through a stationary die 23 to the pull-off drum 68. Each strand is tensioned and is wound back upon its reel 29, when the machine is reversed after a break, by a 'belt 34 passing over a pulley 35, which is carried by a spring-pulled yoke 38 and is driven by gearing from a spring drum 43 or an electric motor. The motor 70 driving the shaft 16 and the pull-off drum 68 is provided with a spring- pulled controller 82 adapted to be held in operative position by the armature 79 of an electromagnet 73. When one of the strands breaks, it flies outwards by centrifugal force and contacts with an insulated rod 75 extending the full length of the machine and thus completes the circuit to the electro-magnet 73, whereby the armature 79 is lifted, the controller 82 released, and the motor 70 stopped. In a modification, the movement of the armature allows a weight to fall, thus releasing a spring-pulled lever connected to a belt. shifter. Rollers 63 carried by brackets 62 adjustable on the frames 15 are provided to hold the wheels 18 in position.

Abstract: 1384961 Vehicle control system WERKZEUGMASCHINENKOMBINAT 7 OKTOBER BERLIN VEB 28 Jan 1972 4106/72 Heading B7N [Also in Division G3] In an arrangement for moving a vehicle 5 along a transport track 1 to a selected one of stopping places 2À1 to 2À6, the place is selected by operation of the appropriate one of the selection switches 7À1 to 7À6 and the movement is controlled by creep speed and stop cams 5À1 and 5À2 on the vehicle which co-operate with creep speed switches 3À1 to 3À6 and stop speed switches 4À1 to 4À6 on the track at the stopping places. Assume a vehicle at stopping place 2À5 has to be moved to place 2À2. Select switch 7À2 is operated and on operation of start switch 24, positional relay 6À5 is picked up via a contact of the creep speed switch 3À5 and closes its contacts 11À5 and 21À5. A left direction relay 15 can now be picked up via contact 7À2, OR gates 9À2 to 9À5 and the right contact 11À5 of the positional relay and also a fast relay 17 is energized via the same circuit and OR gate 16. As the vehicle moves leftwards stop switch 4À5 is released closing the circuit formed of stop switch contacts 4À1 to 4À6 in a hold cicuit for direction relay 15 and speed relay 17. At each stopping place the associated position relay picks up but this only acts to reoperate the energizing circuits for the held relays as their hold circuit is opened by the stop contact. At the stopping place 2À3 in advance of that selected pick up of the positional relay 6À3 closes contacts 21À3 whereby a circuit is completed via diode 19À2 of the matrix 18 to forward speed relay 22 which on pick up releases fast speed relay 17 and acts to reduce the vehicle speed in approach to the selected stopping place. As the creep speed cam operates switch 3À2 at the selected place, creep speed relay 23 is energized via contact 7À2 and the left switch contact 3À2. This acts to reduce speed to a creep value and also opens the circuit to the relays 17, 22 and the direction relay 15. As the stop switch 4À2 is operated the direction relay hold circuit is broken and the relay drops away and stops the vehicle. For movement in the opposite direction, right direction relay 14 is operated via the OR gate chain 10, and the forward speed relay is energized via the 20 series of diodes in the matrix.
