Abstract: A circuit source has bias and modulation current generators for both p-type and n-type optical sources, and a pair of sources of control voltages for the bias and modulation current generators, which obtain pairs of control voltages from an adjustable driving current. An external signal allows selecting, by means of a control logic and CMOS gates, the generators required by the source. The circuit is made by using three pads of an integrated circuit, one for each control voltage source and the third comprising the current generators, the CMOS gates and the control logic.

The sealant layer provides excellent seal strength and excellent adhesion to meat, particularly poultry, even during hot water immersion.

Abstract: A conducting housing for use in a coaxial cable distribution system is of larger length than width and defines an RF signal path therein. A part of the RF signal path is the inner conductor of inner and outer approximately co-extensive conductors. The inner conductor except near its ends has only air separating it from the outer conductor. The outer conductor will usually be of a U-shape lying, in section, on three sides of the central conductor. The outer conductor may be structually combined with an insulating plate supporting the remainder of the RF circuit.

Abstract: Convoluted tubing of thermoplastic resin is made by extruding the resin as a molten tubular extrudate, feeding said extrudate into the interior of a rotating tubular member which has a helical thread in the interior of said member, the spiral thread having a deformation zone receiving the extrudate and a cooling zone downstream from the deformation zone. A vacuum can be used to force the extrudate against the spiral thread in the deformation zone to spirally convolute the extrudate. The rotation of the tubular member causes the resultant convoluted tubing to engage the spiral thread in the cooling zone for conveyance through such zone. Apparatus comprising the rotating tubular member with the interior thread for forming the convoluted tubing is provided.

Abstract: Apparatus for forming a twisted wire tie, includes a wire guide member moveable between an open position for receiving a workpiece, such as crossed reinforcing bars, and a closed position for guiding a length of wire around the bars. An abutment is engageable with the workpiece to hold the workpiece clamped between the guide member and the abutment and adjacent to a wire twist member engageable with opposite ends of a length of wire to form the twisted loop type closure or tie. Feed mechanism comprising opposed rotary feedwheels or a linear actuator and spaced apart wire clamps operate in conjunction with closure of the guide member to a wire receiving position to feed wire to the guide member. A wire holder and drag force exerting plate is supported adjacent to the twist member for engagement with the wire ends to impart drag forces on the wire as it is twisted to form the closure.

Abstract: In one form of game the player observes and must quickly respond to the rapidly changing conditions of one or more visually observed displays such as lights to avoid being sprayed by a liquid discharge. The games is so constructed that to effectively play the game the player must generally continuously observe the condition of the lights; to do so the player must maintain her face in position to be sprayed. Alternatively, the timing of the discharge may be tied to the player's game playing activity or may even occur on a random or apparently random basis.
