Abstract: An automatic covered wire cutting and stripping method and an apparatus used for the method. The method comprises the steps of transferring a covered wire by a transfer mechanism toward a cutting mechanism disposed opposite to the transfer mechanism so as to protrude the covered wire from the cutting mechanism by a specified length in the direction away from the transfer mechanism, cutting a cover of the covered wire by the cutting mechanism to prepare the specified length of a cover part to be stripped, transferring the covered wire toward the transfer mechanism, gripping the cover part to be stripped off the covered wire by a grip mechanism, and transferring the covered wire toward the transfer mechanism such that the cover part to be stripped off the covered wire is gripped by the grip mechanism thereby stripping the specified length of the cover from the covered wire.

Abstract: A compliant S-shaped lead for resiliently supporting an integrated circuit chip package in spaced relation generally parallel to a printed circuit board. The S-lead bends and twists to absorb forces which would otherwise be exerted on solder joints due to temperature cycling and vibration. The symmetrical S-lead self-centers on both the package and PC board to provide minimum stress. The leads are held by a support strip for connection to the chip carrier. Thereafter, the support strip is removed and the carrier positions the leads for connection to the circuit board.

Abstract: A static, flow-conditioner apparatus comprising a series of closely spaced shearing edges which contact and condition liquid flowing thereby. The edges are advantageously carried on propellor-shaped articles and mounted on an axial shaft in conduit forming a confined liquid flow space. It is advantageous to modify flow patterns by changes in edge configuration and flow patterns within spaces between closely packed group of the shearing edge-bearing members. Particularly, utility is found in reducing the asphaltene "particles" or "globules" in heavy fuel oil to extremely small size so they are readily burned in a boiler with reduced particulates in the stack effluent.

Abstract: A variable-volume turbocharger device comprises at least two exhaust gas passages (A), (B) different in the flow characteristics, divided by a partition wall (20) provided in a turbine housing (18), and two valve members (34a), (34b) which are actuated so as to open and shut the exhaust gas passages (A), (B). The valve members (34a), (34b) each are actuated to open and shut in response to the speed and load of an engine or the likes, whereby either one of the exhaust gas passages (A), (B) or both of them are opened to provide at least three turbine flow characteristics. An exhaust gas turbine (12) can be thereby operated with remarkably good efficiency suitably to the operating state of the engine.

Abstract: A method for fabricating an electrical energy distribution system as a track having a multitude of parallel insulating strips and interspersed conductor bars with gaps between adjacent conductor bars to receive conductive blades of outlets or jumper cables for receiving power from the system as well as fixedly supporting a set of blades for power input to the system. During fabrication, the elongated insulating strips and conductor bars are passed through at least two spaced apart transverse multi-apertured separators so that the conductor bars define therebetween blade receiving gaps. As thus fabricated, the system is modular and may be assembled without the need of tools or specially trained electricians.

Abstract: Method for stabilizing a glide shoe loaded against an inner face of a revolving mantle of a roll adjustable in zones. The glide shoe is supported by an articulated joint on a piston which loads the glide shoe with adjustable pressure. In order to ensure lubrication of the glide face between the glide shoe and the inner face of the roll mantle, within an area of a front edge of the glide face as seen in a direction of rotation of the roll mantle, a shifting and/or steepening of compression pressure applied by the glide shoe through lubricant onto the inner face of the roll mantle is produced by means of a wedge space within the front edge of the glide face, said shifting and/or steepening in turn generating a moment having a direction opposite to a direction of a moment produced by frictional force of the glide face of the shoe. The thickness of the lubricant film is increased by this moment in the area of the front side of the glide face.
