EGD apparatus includes a fluid flow path having a rectangular cross-section, which increases in the direction of fluid flow, with confronting corona and attractor electrodes on opposite walls of the flow path. In the construction shown, a plurality of flow paths 13 are provided by walls 12 secured within duct casing 14 and the intermediate walls carry corona electrodes 18, serving adjacent paths, and the other walls carry attractor electrodes 20. Collector electrodes 22 are provided at the downstream end of the duct. The corona electrodes are connected to a negative supply and the attractor electrodes to a positive supply through connectors 46, 48 respectively to provide an ionizing field producing negative ions in the fluid. Successive confronting pairs of electrodes are connected to a potential divider resistor 44, which may comprise a film of resistive material deposited on the outside of casing 45, and a high impedance load is connected across the ends of the resistor. In an alternative embodiment, Fig. 5 (not shown), each wall may carry attractor and corona electrodes with each confronting pair connected in parallel with the supply and feeding a low impedance load. In a further modification, Fig. 2 (not shown), the walls may be formed of dielectric wire like elements and the corona electrodes provided by a wire. The interelectrode spracing is preferably 1-5 mins. The attractor electrodes may comprise either a conductive strip, applied to the surface of the dielectric walls by thin film deposition or spray coating, or a bar like element forming part of the wall. The corona electrodes may be similarly constructed but use a plurality of strips or parallel thin wires which are embeded in grooves in the wall. Suitable electrodes are refractory ceramics, e.g. zinconium diboride, and the walls are made of refractory insulating material, eg, alumina, magnesia or boron nitride for high temperature operation. Two EGD converts may be connected in parallel opposition with a load and by controlling the ionizing current supply or the working fluid supply, A.C. is generated. Alternativerly four converters may be connected in a bridge network to provide A.C. Examples of the connections necessary to generate a multiphase A.C. supply are also given. The apparatus may be used as a fluid accelerator by supplying a voltage to it and altering the connections to the electrodes.

Abstract: 1453842 Tracer apparatus HYPER-LOOP Inc 5 Dec 1973 [11 Dec 1972] 56407/73 Heading G3N In tracer apparatus, in which machine drives are operated for X and Y co-ordinates of machine element motion, see Fig. 1 (not shown) in response to the deflection angle of a stylus in a tracer head, digital signals representing the cosine and sine of the deflection angle are formed and multiplied by a digital amplitude signal manually selected to represent a desired feedrate. The A.C. signal from the tracer head, itself activated by source 9, is processed in a circuit, Fig. 5A (not shown), to provide a ramp signal at point (118), whose crossings of a reference voltage level { ground } are detected to provide on line (144) pulses; synchronized to clock generator 56; whose timing represents the stylus deflection angle. The pulses on line (144) control gates (146) to open the path from the counter to read only memories 172, 178, for one count only, for each complete cycle of counts of the counter 160, the gated count value representing the deflection angle. Each read only memory is set to provide the sine of its input, inverters 176 ensuring that there appears on lines 180 a representation of the cosine. The outputs of the most significant bit stages of counter 160 are de-coded to define the quadrant of the angle, Fig. 3 (not shown). Binary multipliers 188, 182 receive the cosine and sine signals, and a desired feedrate signal, set via manual switches 60 to control multiplier 196, the multiplier outputs being the digital control signals, fed via leads (14, 16, Fig. 1) to the machine axis control servos including resolvers (28). The supply 9 may be a divided output of generator 56, and serves to reset, via units 147, 148, the counter 160, the tracer output signal being an A.C. signal of the same character as the supply 9, but phase shifted in accordance with the stylus deflection angle.

Apparatus for bending wire into an endless ring and welding the free ends together comprises a pair of arms 11, 12 with clamps 13 to grip the wire and which rotate through 180 degrees to bring the ends of the wire together for welding. The wire is fed through a straightener 1 by feed rollers 3, 5 until the leading end abuts a stop 15. The wire is cut by a shear 4 and gripped by the arm 12. The feed rollers 5 slip on the wire and the stop 15 is removed. The arm 12 pivots to pull the severed end through the rollers 5 and it is gripped by the arm 11 which pivots through 180 degrees simultaneously with the arm 12 to bring the ends together. Several cutter blades are mounted side by side in the shear 4 and are selectively actuated by solenoids to cut different wire lengths and hence difference size rings are formed. The arms are mounted on a carriage 10 which moves horizontally while the arms are pivoting to a welding unit 7. An arm 8 then transfers the ring to a flash removing and strength testing unit 9. The movement of the arms and the clamp is controlled by cams (not shown).
