Title: Method of constructing a heat exchanger
IPC: B21D53/08
Filed: 1968-12-20
Abstract: 1,245,998. Making heat exchangers; angular bending. SUNDSTRAND CORP. 20 Dec., 1968 [26 Dec., 1967 (2)], No. 60820/68. Headings B3A and B3E. A heat exchanger comprising a plurality of fins through which passes a continuous sinuous tube having straight sections, in 360 degree engagement with apertures in the fins, linked by oppositely directed bends 101 is made by stacking a plurality of fins 36 having apertures in alignment to form continuous openings through the stack and threading a tube back and forth through the stack. The tube is threaded through an opening and gripped by a pull head 15 and pulled through the opening, the pull head being mounted on a trolley 21 moved by a fluid-operated piston and cylinder 27, 26. The pull head has bars 71, Fig. 2, which have nuts 50 which engage a reversing device 16. At the end of a pull the reversing device grips the tube, which is released by the pull head, and turns it through 180 degrees around the member 54, Fig. 6 (not shown), the length of tube extending from the reversing device toward the stack of fins being sufficient to pass through the next opening and be gripped by a second pull head 18 on the far side of the stack. The first pull head is then reversed, engages the reversing device and pushes it toward the stack causing it to thread the tube through the next opening. A device 73, Fig. 3, comprises two arcuate ends 83, 84 which are separable by means of piston and cylinder assemblies 81, 79 and 85, 78. The tube passes through a guide 90 and around the annular groove formed by the ends 83, 84 in order to form the bends at each side of the stack. After a pull is complete and a bend formed the arcuate ends are separated and the stack indexed to present the next opening to be threaded with tube. The fins are preferably spaced by collars around the apertures but may also be threaded with tube and then spaced along the tube by means of a spreader comb, Fig. 12 (not shown). After the tube has been threaded into the fins it may be expanded, to ensure 360 degree engagement, by means of fluid pressure or by passing a ball through it. Alternatively the tube can be brazed to the fins.

IPC: H01H33/86
Filed: 1968-12-23
Abstract: 1282569 Gas blast circuit breakers ASSOCIATED ELECTRICAL INDUSTRIES Ltd 10 March 1970 [23 Dec 1968] 61032/68 Heading H1N A gas blast interrupter comprises hollow contact assemblies 5 and 7 with associated exhaust valves 17 and 67, the first of which is housed within contact assembly 5. Assembly 5 comprises a slidable tubular contact 9 having a nozzle 13 communicating with a discharge port 15 by means of the exhaust valve 17. This valve comprises a slidable piston 19 mounted on the contact member 9 which has ports 23, 25 communicating with chambers 21, 27 respectively. Piston 29 controls the discharge port 15 being biased towards the closed position by spring 31. Contact assembly 7 comprises a slidable tubular contact 33 connected by webs 37 to tubular operating member 39 biased to the closed contact position by spring 41. Piston 43 at one end of the member 39 is slidably mounted within a chamber 45 having ports 47 and 49 controlled by pistons 43 and 51 respectively. The exhaust valve 67 comprises a piston 71, biased to its closed position by spring 77 and controlling the ports 79, 83 and 85. Duct 59 connects port 49 with a port 63, the latter of which is controlled by a slide valve 61 operated by a push rod 69. When the push rod 69 is moved downwards from the position shown, compressed air from chamber 45 passes to the lower face of the piston 71, opening the exhaust valve 67 and allowing contact 33 to move back into its housing 35. Contact 9 follows the contact 33 initially due to a pressure differential across the piston 19, which then opens port 15 allowing the compressed air within contact 9 to be released. The gas blast occurs on the separation of the two contacts which allows compressed air in the housing 1 to pass through the nozzles 13 and out through exhaust ports 15 and 79. Reclosing the contacts is achieved by pushing the rod 69 upwards thus linking chamber 45 with the high pressure air in the column 3, thus enabling spring 41 to reclose the contacts.

Title: Drying wood pulp
IPC: D21C9/18
Filed: 1978-10-05
Abstract: Wood pulp is dried by contacting it with heated air and subjecting the air and pulp to turbulence in a dryer 2 comprising relatively contrarotating members 15, 16 which intermesh on rotation so that dried wood pulp fibres are suspended in the air issuing from the dryer via exit passage 24. The heated air is produced by heating air in a burner 1 to a temperature of from 300 DEG  to 600 DEG C by burning a fuel, issuing from a jet 5, in the air. The dried wood pulp fibres are separated from the air in a cyclone separator 3 and a portion of the air thus separated is recycled via pipes 30 and 32 to the burner 1. The air admitted to the burner 1 comprises fresh air introduced through an inlet, and recycled air introduced through an inlet 6 from the pipe 32, the proportion of fresh air being such that the heated air contacting the pulp has an oxygen content of less than 10 per cent by volume. The use of recycled air reduces the risk of fire when drying the wood pulp. <IMAGE>
