Abstract: A supercharging system includes a fan providing an air flow, and a prime mover that drives the fan. A duct directs a first portion of the air flow to a gas turbine system, a main bypass subsystem diverts a second portion of the air flow to a heat recovery steam generator; and a drive bypass subsystem that diverts a third portion of the air flow to the prime mover. The prime mover may be one of an aeroderivative gas turbine, a gas turbine, a reciprocating engine, a steam turbine and an induction motor and a variable frequency drive.

Abstract: A supercharging system for a gas turbine system having a compressor, a combustor, a turbine and a shaft includes a prime mover and a fan assembly that provides an air stream at an air stream flow rate. A hydraulic coupler is coupled to the prime mover and the fan assembly and a second torque converter may couple the supercharger prime mover to an electrical generator. The supercharging system also includes a subsystem for conveying a first portion of the air stream to the compressor, and a bypass subsystem for optionally conveying a second portion of the air stream to other uses.

Abstract: A device for forming an encapsulated end of a wire bonded to a metal surface. The device includes a clamp being an end surface of a bar is pressed against a surface of a plate. The end surface has a ridge formed around its edge. Therefore, when a clamping force is applied to the bar against the plate, the metal sheet clamped between the plate surface and end surface of the bar, the clamping force is concentrated at an interface between the metal surface and ridge. When encapsulate is injected into the contact region, the ridge prevents contaminating material from migrating over interface between bar and plate where the welding step is to be performed. The bar is then withdrawn leaving a tunnel through which the wire is positioned with the end of the wire in contact bondable to the clean surface of metal. The wire is positioned in the tunnel and bonded to the metal surface.

Abstract: A telescopic extendable nozzle attachable to a pressurized source of gas. The nozzle permits blowing out otherwise inaccessible crannies with the nozzle extended or providing a blast of air over a wide area as required. An anchor section of the nozzle has an exit end connect connected to the entrance end of the telescoping section and an entrance end of the anchor section is connected to the exit end of the source. The anchor section has a passageway escape for gas that prevents sudden build up of pressure when the exit end of the nozzle is inadvertently obstructed. In one embodiment, the anchor section comprises an outer sleeve slidably mounted on an inner sleeve, both sleeves having apertures providing an adjustable passageway. A plug is positioned inside the inner sleeve and has a central bore for passing gas through the nozzle and a plurality of planet bores that provide relief from excessive pressure such as when the nozzle is inadvertently and suddenly stopped up.

Abstract: Apparatus and a method for processing work pieces, such as semiconductor lead frames, wherein the apparatus includes a power device such as a solenoid assembly, for driving an upper die into processing relationship to a work piece on a lower die with the stroke of the power device being relatively short, such as in the range of 0 to 0.375 inch. This is achieved by providing a second power device, such as a piston and cylinder assembly, in which the piston rod of the assembly raises the upper die high enough to allow clearance between the dies for the passage of the work piece between the dies, then the second power device is allowed to lower relatively slowly until the upper die is substantially in proximity to the work piece.

Abstract: A semiconductor lead frame suitable for making electronic components from semiconductor chips. The lead frame is of one-piece construction and is provided with a pair of spaced outer side strips and a plurality of spaced cross strips integral with and spanning the distance between the side strips. A plurality of pairs of pads are on the lead frame, there being a pair of spaced pads between each pair of adjacent cross strips. One of the pads of each pair is coupled to the outer ends of a pair of spaced, parallel legs which extend along the adjacent cross strips. The legs are bendable intermediate their ends sufficiently to cause the legs to become doubled upon themselves so that the pad coupled to the leg can be moved from an initial position generally spaced longitudinally from the corresponding other pad to a final position in overlying, spaced relationship to the other pad.

Abstract: A knife has a snap-on tang interlocked with its blade and clamped between handle halves. Transverse and longitudinal locking between the blade and tang resists relative rotation or translation. Butterfly clips on the blade snap onto webs molded into one of the handle halves for resisting relative deformation therebetween. A further butterfly clip on the tang snaps onto a longitudinal web in a handle half for additional rigidity.

Abstract: Apparatus for mounting a pair of die members so that one die member can move toward and away from the other die member. The apparatus includes a pair of spaced die shoes for mounting respective die members and an electromagnetic unit for moving one of the die shoes toward the other die shoe. The electromagnetic unit includes a coil mounted on one of the die shoes and an armature mounted on the other die shoe, the electromagnet and the armature being between the die shoes. The armature is aligned with and partially extends into a recess in the central portion of the coil so that, when current flows through the coil, the armature is attracted to the coil and moves the other die shoe toward the one die shoe. A bias structure biases the other die shoe away from the one die shoe. Such bias structure can take the form of an air cylinder or a spring.

Abstract: Apparatus and method for forming disks or other articles from flexible sheet material. The disks can be used, for example, as substrates of magnetic recording disks known as floppy disks. The apparatus includes an upper die plate shiftably mounted above a lower die plate and having a die thereon so that a strip of material moveable between the die plates can be sequentially die-cut to form the disks. The upper die plate has quick release latches attaching the upper die plate to a support so that, when the latches are retracted, the upper die plate can be quickly and easily removed from the apparatus to permit the die to be sharpened or replaced. The apparatus includes air delivery ports near the upper and lower die plates to direct air under pressure against a disk after it has been die-cut from the strip so that the disk will be moved laterally and into a chute and onto a spindle which receives a stack of the disks.

Abstract: Apparatus and a method for processing a semiconductor lead frame, such as deflashing a plurality of molded chip housings on the lead frame as they move along a predetermined path. A support has a pair of sides, and a track on each side respectively, one track guides lead frames upwardly in a first stack to a position laterally aligned with a die on a vertically movable die plate. The other track receives processed lead frames and allows the processed lead frames to be lowered in a second stack. A reciprocal shuttle member extending between said tracks strips off the uppermost lead frame from the first stack and moves it into a position beneath the die which is then lowered by a power device sequentially to process, i.e., deflash, the lead frame. Then, the die elevates, allowing the shuttle member to reverse so that it can pick up the top lead frame from the first stack to advance it along with the processed lead frame laterally, the processed lead frame being movable onto the second stack.
