Abstract: A method for removing selected integrated circuit dice from a wafer array of dice sequentially moves a striker above a tape to the underside of which the array is mounted and the knocks a die down from the array of dice into a receptacle for transport to further processing stages.

Abstract: An apparatus for removing integrated circuit chips from a flexible carrier characterized by a base, a separator plate including a separator edge coupled to the base, a take-up drum rotatably attached to the base and adapted to draw the flexible carrier past the separator edge, a tensioning mechanism for providing a tensioning force on the flexible carrier, and a conveyor for transporting separated chips away from the separating edge. The take-up drum and conveyor mechanism are simultaneously operated by rotating a knob.

Abstract: A method for feeding chip components to positions in which they can be picked up by transfer members, in which the chips are pushed out of a feed channel while being held between an ejection pin and a transfer member part. An elongated part of a transfer member is advanced into a feed channel into contact with one side of a chip, an ejection pin then advances to the other side of the chip and pushes the chip and transfer member out of the feed channel through a removal opening, and the chip is then held by the transfer member while the ejection pin retracts. Preferably, a cover plate prevents movement of the chips toward the transfer member until the member is in contact with the side of the chip.

Abstract: A repetitive combustion coating apparatus for applying coatings of particulate materials such as powdered tungsten carbide and other metal alloys by discharging discrete quantities of material encapsulated in an elongated tape into a combustion chamber and igniting a fuel-air mixture therein to deliver the charge of combustion gases and entrained particulate material through a nozzle to impact the article to be coated. The apparatus includes a rotary indexing wheel over which the encapsulated tape is trained with the spaced apart capsules nested in circumferentially spaced supporting receptacles. The indexing wheel is mounted on support arms which permit limited linear reciprocation so that a ratchet mechanism incrementally indexes the wheel and permits linear movement of the wheel to successively clamp the tape capsules against a clamping die.

Abstract: A child-proof dispenser includes a container (11) having an inner shell (15) covered by an outer shell section (18) to form an inner compartment (12) enclosing a coiled strip of blister-packaged drugs (13) or the like. The inner and outer shells are releasably interlocked together by central hub portions (31, 25) which support the outer shell for rotation relative to the inner shell. The outer shell is rotated away from a stop (46, 47) and against the action of a compression spring (48) to aline inner and outer dispensing openings (42, 45) in the inner and outer shells, respectively. An ejecting trigger (55) carried by the outer shell is moved relative to both shells against the strip in a guide passage (46) to advance a selected number of doses of drugs via the dispensing openings. Upon release of the shells, the compression spring moves the outer shell to a position to cover the inner dispensing opening.

Abstract: This invention is in the field of automatic machinery and in one embodiment useful for removing the contents of "blister" packages in ribbon form, comprises a group of three in-line die blocks, which move together in a square motion, having a lateral distance of motion equal to the distance between blister packs on a common ribbon. Sequentially, the first is a positioning die, the second includes a bottom-positioned upward moveable perforating die to perforate an exit hole in the bottom of the package, and the third includes a top positioned downward moveable punch for impinging on the top of the blister and forcing the contents of the package out through the perforated exit hole.

Abstract: Apparatus for sequentially feeding headed fasteners such as rivets includes a carrier band of resilientily stretchable material with the fasteners driven through undersize holes equally spaced along the band, the band being advanced intermittently by a reciprocating actuator, toothed for simultaneous engagement with several of the fastener heads, to bring the fasteners in sequence between a striker and the entry to a delivery conduit, the striker being reciprocated to drive each fastener brought into alignment therewith into the delivery conduit, the fastener head being forced through the stretchable band, a jet of air through the striker impelling the fastener through the delivery conduit.

Abstract: A guide strip for holding a succession of fittings which are to be hammered into box-shaped containers in a studding machine and for conveying such fittings into the machine, the strip being constituted by a tape-like foil presenting a succession of nests for holding such fittings.

Abstract: Elements are supplied to a work station with the elements being arranged in a row. The elements are releasably retained at the work station. The articles to which the elements are to be transferred are moved through the work station with the row of elements at the work station extending in the same direction as the direction of article movement. Each of the elements is transferred to an associated article as the articles are moved through the work station. The elements are sequentially transferred with the most downstream element always being the next element to be transferred.

Abstract: Single product units are dispensed by a machine previously loaded with a band-shaped package thereof in a feeding station being a container. The first product unit of the band-package is positioned at a stop device, adjustable for a different size of the products, from which a caliper grips and draws the first unit to a cutting station, where a blade, co-operating with a backing blade severs the same from the band-package. The severed product unit passes through an aperture formed in a plate for supporting the blade and falls into a dispensing compartment. If it is the case, an oven is provided along the path of the single articles for heating or baking foodstuffs such as toasts and the like. Known timing devices and relay contacts are provided for the correct operation of the machine.

Abstract: A fastener feed assembly for a tool such as a power screwdriver having a drive member such as a rotatable bit includes a base fixed to the tool and a nose assembly slidably related to the base. The nose assembly includes a workpiece engaging surface, and when the tool is moved toward the workpiece during a fastener driving operation, the base moves toward the nose assembly. A return spring separates the base and nose assembly when the tool is withdrawn away from the workpiece. A strip of fasteners is fed from a magazine along a feed path through the nose assembly with sequential fasteners located in a drive position. Normally the drive member is spaced from a fastener in the drive position. During movement of the tool toward the workpiece in a driving operation, the drive member moves into engagement with a fastener in the drive position, and then continues to move in order to drive the fastener into the workpiece. A pawl is engageable with the strip in order to advance the strip along the feed path.
