Abstract: The present invention proposes a method of manufacturing semiconductor devices from an elongated leadframe by using a differential overlapping apparatus. The leadframe has longitudinally spaced pairs of staggered leads. The overlapping apparatus functions to deform the leadframe during transfer thereof, so that each pair of staggered leads assumes the same longitudinal position but displaced away from each other perpendicularly to a plane containing the leadframe. The leadframe is further deformed to cause the pair of leads to move toward each other, so that a semiconductor chip is sandwiched between the pair of leads for bonding.

Abstract: A method for producing an integral bottle/collar combination for use in a package for storing and dispensing potentially dangerous material such as medicament tablets. The package is resistant to opening by children yet readily openable by adults. The process includes a step of injection molding a polymeric part having a finish portion, a preform portion, and a flange portion. The flange portion has at least one integrally formed socket having a resiliently deformable pushtab connected by a hinge. The preform portion of the injection molded part is blow molded into the shape of the bottle. The hingedly connected pushtab is then folded into its in-use position.

Abstract: Method of manufacturing a tube coupling body in a plastics material using injection moulding tooling. The body is formed with a cylindrical bore having enlarged end portions in a mould body and using removable cores. The cores form both the internal bore of the mould body and also end parts of the mould body so that once the cores are removed, end parts of the coupling body are revealed in the mould. While the end parts are still hot from the initial moulding operation, forming dies having tapering end cavities are pressed over the end parts of the moulding to form the end parts of the moulding with both external and corresponding internal tapered surfaces. The tapered internal surfaces of the end parts thus formed provide tapered cam surfaces for engaging the resilient arms of collets to be inserted in the coupling body to receive and lock tubes in the coupling body.

Further, when the terminal is attached, the core can be moved to a proper position in relation to a terminal attaching means (400) according to a type of terminal.

Abstract: A flexible elongated resistance heating element of improved uniformity and ease of termination has a continuous strip of resistance wire formed about a flexible elongated strand of insulating material in a generally helical pattern of nonuniform pitch with regions of increased pitch and correspondingly reduced turns density which regions experience little increase in temperature when the element is energized. The pitch of the helical resistance wire pattern varies as it approaches each of the ends of the element to provide a region of increased pitch followed by a region of decreased pitch at each end. Shorting wires may thereby be eliminated. An insulating coating surrounds the resistance wire and strand and electrical terminals are connected by crimping to the regions of decreased pitch of the resistance wire at the ends. The heating element may be bonded to a support member in a serpentine pattern with the cool end regions extending freely from the support member.
