Abstract: 1,051,682. Making contact strips; welding by pressure; forging. STANDARD TELEPHONES & CABLES Ltd. Dec. 20, 1963 [Dec. 28, 1962], No. 48862/62. Headings B3A, B3H and B3R. In a machine in which strip like members to which contacts are to be attached are moved past a number of working stations, contact material in wire form is fed to each strip at one station, the end of the wire is welded to the strip, the wire is cut adjacent to the weld point, the strip is advanced and at the next station the contact material is formed to the desired shape by squeezing. Relay contact springs are fed by hand or automatically into a gravity fed magazine and they pass on to a transfer bar 3, Fig. 1 (not shown), having pairs of pins 4 to fit holes in the springs which conveys them from station to station by a " lift and carry " motion effected by a crank device to provide each portion of the bar with a circular motion during each advancing step. On each upward movement of the bar one pair of pins carry a new spring from the magazine and move it along the line, disengaging to leave the spring supported on longitudinal supports. When a spring reaches a welding head 5 silver wire 14, Fig. 2 (not shown), is fed down the centre of the upper hollow electrode, is urged against the spring over a lower electrode 13 of polished chromiumcopper alloy and welding current is switched on. Two adjustable cutter jaws 15, 16 close on the welded wire and cut the contact stud to required length. The transfer bar moves again and positions the spring plus contact on head 7 where the contact stud is squeezed between a stationary upper die 21, Fig. 3 (not shown), and a movable member 23 to form a dome thereon. The member 23 is moved by a cam follower 25. The transfer bar advances the spring to a second welding head 8 and forming head 9 where a second contact is welded and shaped. The springs are then advanced to fall into a bin 10. The operation of the wire feed, of the heads, the switching on of the welding current and the operation of the cutters are controlled by a camshaft whose rotation is synchronized with the transfer bar motion. The heads may be arranged in a curved line.

Acidic alkali metal chloride brine saturated with chlorine and at 50-95C, from a mercury cathode electrolytic cell (11) is passed into a zone (20) in which a vacuum is produced by connection with a condenser or absorber (33) having a barometric leg (34) to which an alkaline alkali metal chlorine brine at below 40C is passed. The chlorine thus removed from the acid brine dissolves in the alkaline brine which is then returned to the electrolytic cell. As shown in the Figure, to which the above numerals relate, the zone 20 also has a barometric leg 21 through which the dechlorinated brine passes into a zone 22 where it is resaturated with salt and caustic soda, and the alkalized brine is thenpassed through line 27 for chlorine absorption in the condenser or absorper and recirculation to the electrolysis cells via a tank 29 where the pH is adjusted with hydrochloric acid. A spray separator is provided at 37 to which air may be admitted to control the vacuum in the dechlorinator 20.

Abstract: 1,226,106. Nuclear fuel assemblies. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 13 June, 1968 [21 June, 1967], No. 28746/67 Heading G6C. Fuel rods 1 forming part of a fuel assembly of breeder fuel in a fast reactor have plain cylindrical surfaces 1a, the coolant flowing along the intervening spaces 2 in a direction parallel to the fuel rods. To control the coolant flow, a flow restrictor 3 comprising a wire or rod of the necessary diameter is placed in the spaces 2, the restrictor having a helical fin 4 for spacing the rods 1 and for imparting a turbulent flow to the coolant. The rods 3 have different diameters to give different flow rates in different parts of the reactor but the external diameter of the fins 4 is the same for each rod.

Abstract: 1,228,341. Ploughs. SHELL INTERNATIONAL RESEARCH MAATSCHAPPIJ N.V. 2 Jan., 1969 [4 Jan., 1968], No. 230/69. Heading A1B. [Also in Divisions E1 and F2] A tool 18 is driven by a so-called sonic vibrator consisting of a drive means 23 which is connected to the tool by a spring or springs consistuting a spring unit (see Division F2) whose spring rate is different in opposite directions. The tool and spring unit thus constitute a resonant mass-spring system whose natural vibrations have a non-sinusoidal wave form. The connection is such as to give the tool a high velocity working stroke and a low velocity return stroke. In the case of an earth-working tool such as a trench digging machine, Fig. 1, the low velocity return stroke need not cause the tool to move away from the work face but rather remain in contact with it and cause the tool-carrying mobile structure 11 to move in the direction of the justcompleted working stroke: i.e. the energy of the return stroke of the tool is employed as a source of motive power for the machine as a whole. The invention is applicable to other earth-working tools, e.g. ploughs and pile drivers, and also to paint scrapers.

Abstract: 1,230,059. Hospital bed. DOMINION METALWARE INDUSTRIES Ltd. 12 March, 1970 [13 March, 1969], No. 11827/70. Heading A4J. The head supporting section 56 of the bed is hinged to the seat support 58, the latter being carried on a sub-frame mounted on rollers 54 that run on a frame 23. Linkages 81, 70 allow the head section to be adjusted by an electric motor 38 whilst keeping the head end 57 in the same vertical plane. A leg section 60 is pivoted to the seat section 58 and also operated by an electric motor, whilst the foot action 62 is manually adjustable. Frame 23 is vertically adjusted by a parallel linkage between it and a floor engaging frame.
