Title: Flexible tubing
IPC: B29C53/60
Filed: 1973-11-05
Abstract: 1451469 Making flexible tubes ATCO RUBBER PRODUCTS INC 5 Nov 1973 [9 Nov 1972] 51290/73 Heading F2P A flexible tube consists of a helically wound strip R (Fig. 8) of polymeric material, the edges of the strip R being overlapped and fused to each other, and a helically coiled wire W which is sandwiched between the overlapping edges of the strip R. The tube is made by winding the strip R, which is produced by an extrusion head 32 (Fig. 2) and wire W onto a set of rollers 18a-l arranged in a generally cylindrical pattern, the rollers 18a-l being individually rotatably mounted and having peripheral grooves 24 therein, the rollers being skewed in their generally cylindrical pattern to cause the grooves 24 to collectively define a helical advance path for the. wire W. As described the rollers 18 are mounted, at one end, in self aligning bearings 44 in a fixed plate 20 and at the other end in self aligning bearings in an adjustable plate 38. The plate 38 is mounted on a central cylindrical member 80 by means of bolts 98 and slots 97 which allow the angular disposition of the plate 38 to be adjusted. This varies the skew of the rollers 18a-l and thus adjusts the pitch of the helical advance path defined by the grooves 24. The rollers 18a-l are driven in unison by an electric motor 54 via chain and sprocket devices 70, 72, 78. In use the extruded strip R is guided onto the rollers 18 by a roller 108 (Fig. 2) and the wire W is guided so that it lies on one edge of the strip R and engages the grooves 24. The edge of the next turn of strip R overlaps the wire W and previously laid edge to enclose the wire W as shown in Fig. 8 and the two edges are fused together by a pressure roller (not shown). Cooling air is directed to the interior of the tube as it is formed, via apertures in the central member 80, a conduit and a blower (not shown). As the tube is formed, it advances from the rollers 18 and is supported by rollers 102, 104 mounted between plate 38 and plate 100 on an extension 86 of member 80. Alternatively, especially when long lengths of tube are being produced, the formed tube may be supported by an air bearing conveyor (not shown). The apparatus also includes a cutting device 26 for cutting completed lengths of tubing.

Title: Method of making printed circuit board
IPC: H01B1/00
Filed: 1964-12-17
Abstract: <PICT:1095117/C6-C7/1> In a method of making a printed circuit, the circuit pattern is formed on an insulating plate 1 in an adhesive medium 2, metallic powder 4 is dusted on to the plate 1 and pressed to bond it to the adhesive pattern, redundant powder is removed, and a layer of metal 5 is deposited on the powder pattern by a chemical reduction process. The insulating plate 1 is preferably of phenol resin laminate, and the adhesive medium 2, which is preferably applied by screen printing and ultimately cured by heating, may be a mixture of epoxy resin and carbon, or of phenol resin, benzyl alcohol and carbon.  The metallic powder 4, which is preferably a catalyst for the subsequent chemical reduction step, may be of Ag, Cu, Fe, Ni, Co, Au, Pt, Pd, or alloys thereof, or powders plated therewith.  In an example, Cu is deposited on a pattern of Cu particles from a solution of copper nitrate, potash soda tartrate, caustic soda, and formaldehyde; in another example, Ni is deposited on Fe particles from a solution of nickel chloride, sodium hypophosphite, and sodium citrate.  To facilitate the soldering of lead wires into holes A, which are drilled or preferably punched through plate 1, adhesive 2', particles 4', and metal layer 5' may be continued into the mouth of each hole A.  In modifications, the rest of the wall of each hole A is sensitized, as by successive immersions into solutions of stannous chloride and palladium chloride, so as to attract a layer of metal during the chemical reduction step.  If the surface of the plate 1 is smooth, redundant sensitizing material can be washed away before the adhesive pattern is applied Fig. 7 (not shown); if plate 1 retains the sensitizing material on its surfaces, a layer of insulating material may be applied thereover Fig. 8 (not shown), or a removable layer of paint may be applied to the surfaces before sensitization Figs. 9, 10 (not shown).  Conductive patterns may be applied to both surfaces of plate 1.

[Also in Division G6] A nuclear power plant incorporates both an M.H.D. generator and a turbo-generator. The coolant gas from a fast nuclear reactor passes first into the M.H.D. region and then into a steam generating heat exchanger which supplies the turbo-generator. The cool gas leaving the exchanger is returned to the reactor. Between the reactor and the M.H.D. generator, a region containing thermal neutrons is formed in a moderating zone. The thermalized neutrons react with the stable isotope He<SP>3</SP>, contained in the heated coolant gas, He<SP>4</SP> in the reaction He<SP>3</SP>(n, p)T. The protons and tritium so formed ionise the He<SP>4</SP> gas which forms the plasma of the M.H.D. generator. The plasma linear velocity is increased during passage through the nozzle-shaped moderating zone. He<SP>3</SP> may be replaced as the ionising agent by Li<SP>6</SP> or B<SP>10</SP> and caesium, or argon may be added as an ionisation activator. In the M.H.D. generator, the external windings providing the magnetic field are energized by part of the current produced in the generator.

Abstract: 1415332 Cryogenic vacuum pumps L'AIR LIQUIDE SOC ANON POUR L'ETUDE ET L'EXPLOITATION DES PROCEDES GEORGES CLAUDE 24 Nov 1972 [26 Nov 1971 7 July 1972] 54541/72 Heading F1N [Also in Division F2]  A cryogenic pump comprises a chamber 1 having an opening 3 for connection to a chamber to be evacuated, a liquid helium filled tank 6 forming a gas condensation surface for pumped gases, and means for varying the pumping speed by varying the flow-rate of the pumped gases, said means being either a cooled valve member 10, Fig.1, positionable to restrict the opening 3 or a condenser 40, Fig.4, the temperature of which is regulated by a valve 12a. In the Fig.4 embodiment high speed pumping is achieved by opening the valve 12a so that liquid helium flows into the condenser 40 from the tank 6. In the Fig. 1 embodiment high speed pumping is achieved by opening the valve 10. The valve 10 is cooled by a heat conducting nickel plated copper braid 15 leading from the member 10 to a liquid nitrogen filled stainless steel tank 5 disposed above the tank 6. A nickel plated copper screen 9, 9 surrounds the tank 6 and is in heat conductive connection with the tank 5, a further screen 9a being disposed between the chamber wall 2 and the tanks 5, 6. The valve member 10 is in the form of a shutter movable transversely across the opening 3 by a rod 11. The rod 11 extends to the outside of the chamber 1 through a bellows seal 32, 29, 27 and is movable longitudinally by rotating a knurled nut 24. In Figs.6 and 8 which show a variant of Fig.1, the valve is in the form of axially spaced discs 100', 100', 614 mounted on an axially adjustable rod 612. In the completely closed position of the valve, the disc 614 seats against a ring 101 bolted to the flange 4 surrounding the opening 3, whereby the pump is isolated from the chamber to be evacuated connected to a flange 102. Opening of the valve 614 provides a restricted path for the pumped gases through perforations 100a, Fig. 8, in the disc 100', the latter being urged by a spring 24 against a cylindrical member 203 having a ring 201 secured by screws to the screen 9, 9'. A length of braid 500 extends  between the ring 201 and one of the discs 100' to cool the latter. As the disc 614 is moved further away from the ring 101, the spring 24 forces a flange 24b on a stem 23 supporting the discs 100' against a member 29 fixed to the disc 614 whereafter all the discs move together.
