Abstract: In a three phase welding power supply, the three phase power is connected to a welding arc by a power control circuit having three conducting paths for straight polarity current and three conducting paths for reverse polarity current. The power control circuit comprises a three phase bridge rectifier circuit (112) having eight bridge arms each including a silicon controlled rectifier (1, 2, 3, 4, 5, 6, 7, 8) with the bridge circuit being connected between the three phase power source (102) and the welding arc (124) which is in turn connected to the three phase power supply neutral (103). An inductor (116) is connected across the direct current terminals of the bridge circuit so that arc currentflows in one direction through the inductor (116) regardless of the polarity of the arc current. The conducting paths are selectively activated at nonzero voltage points to conduct repetitive sequences of independent numbers of straight polarity half cycles of arc current followed by independent numbers of reverse polarity half cycles of arc current to the welding arc. Pulses are generated in synchronism with each of the three power phases and counted to determine the activation sequences of the conducting paths. By controlling the generation of the pulses and the counts of the pulses at which the paths are activated, a variety of sequences are generated.

Abstract: A polymer is prepared by forming a mixture of 3-methacryloxypropytris(trimethylsiloxy) silane, methacrylic acid, cyclohexylmethacrylate, 2-hydroxypropylmethacrylate, m,p-styrylethyltrimethoxysilane, methyl methacrylate and a cross linker. A polymerization initiator is added to the mixture, and UV or thermal energy is supplied so that the mixture polymerizes to form a polymer that is transparent, hard, machinable and oxygen permeable. The polymer is cut into lenses, and the lenses are treated with acetyl chloride or another suitable chemical so that their surfaces become hydrophilic. The result is oxygen-permeable, hydrophilic, daily and extended-wear, hard contact lenses.

Abstract: A breakstem rivet installation tool includes a jaw mechanism (12) for gripping the stem of a rivet, and a pneumatically actuated piston and cylinder device (13) for applying pulling force to the jaw mechanism. It is provided with a damping valve (22) for damping the flow of air from the piston and cylinder device (13) when the force is suddenly released on breaking of a rivet stem (23), thereby to reduce mechanical shock to the tool, and noise of fast-escaping air. The damping valve (22) comprises a resilient steel circular disc (32) which is secured at its centre to the apex of a domed member (28) provided with vent holes (26). The undeformed shape of the disc (32) is flat. When, in use of the tool, a rivet stem breaks and the restraining force on the piston (15) is released, the velocity of air flow past the disc (32) urges the disc to bend towards the domed surface of the member (28), thereby restricting the air flow through the vents (26). It may be that the valve closes completely, so that the peripheral edge (36) of the disc (32) contacts the annular valve seat (37) surrounding the air vents (26).

Abstract: In order to achieve optimum rear cooling of the pole coils (9) in salient-pole machines, a U-shaped guiding device (12), which extends virtually up to the pole cap (5), is pushed into the gap between the pole core (4) and the pole coil (9). The coolant is ducted through the spaces (15, 16) formed thereby. In this way, high coolant speeds are achieved, which lead to increased heat transfer values and hence reduce the conductor temperatures of the pole coils. <IMAGE>

Abstract: A terry loom having a negative pile warp let-off motor is electronically controlled to produce terry having uniform pile-to-ground warp ratio. The negative pile warp let-off motor is controlled to dispense pile warp yarn at a rate which yields the desired pile-to-ground warp ratio regardless of the tension on the pile warp yarn. The desired rate of pile warp let-off may be provided to the loom controller as a known quantity or may be calculated by the loom controller based upon the known desired pile-to-ground warp ratio and a measured or preset ground warp let-off rate. The desired pile warp let-off rate is compared to the actual pile let-off rate, and a signal is generated based upon deviations between actual and desired pile warp let-off rates, to control the pile warp let-off motor. Simplified control with uniform pile-to-ground warp ratio is thereby provided.

Abstract: A process for controlling the conversion of reactor feed to iron carbide is disclosed. The reactor feed is subjected to a process gas in a fluidized bed reactor (10), and the off-gas from this reaction is analyzed (56) to determine its composition and the temperature (64) and pressure (66). A stability phase diagram is generated based on the temperature. Different regions of the stability phase diagram are representative of different products being formed by the conversion of the reactor feed. Based on relative concentrations of the individual gases in the off-gas and the total pressure, a point is plotted on the stability phase diagram indicative of the favored reaction product. The process parameters can then be adjusted to insure that iron carbide can be produced from the reactor feed based on the stability phase diagram. In one embodiment, the rate of conversion of the reactor feed into iron carbide is controlled.

Abstract: An improved radial ply pneumatic tire 30 is described. The improved tire 30 has a first annular surface 23 located between the heel 22B and toe 22A of each bead 33 and a second surface 24 extending radially outwardly from the bead heel 22B. The first surface 23 is designed to be in contact with the bead seat 42 of the design rim 40 when the tire 30 is mounted and inflated to normal pressure. The first annular surface 23, when the tire 30 is unmounted, forms an average angle  beta  with the axis of the tire, when the beads 33 are axially spaced a distance D equal to the design rim width as defined herein. The average angle  beta  is in the range of at least one-half degree and less than three degrees greater than the angle formed between the mating bead seat 42 of the design rim 40 and the axis of the tire. The second surface 24 is designed to be in contact with an annular flange 44 portion of the design rim 40 when the tire is mounted and inflated to normal pressure. The second surface 24 is perpendicular to the axis of rotation. Preferably the angle  beta  is in the range of 1 DEG  to 2 DEG greater than the rim seat angle, more preferably the angle  beta  is 1.5 DEG  greater. The angular relationships relative to the design rim flange 44 permit the bead 33 to exhibit uniform compression upon mounting to the design rim 40, thereby improving the stiffness and handling characteristics of the tire 30. <IMAGE>
