Abstract: Handheld and stationary hot air solder reflow apparatus for repairing, reworking or producing electronic components and circuit boards of the type having a means for supplying a flow of hot air to an outlet tube are provided with a nozzle adaptor which has an internal adapter body which is resiliently carries a support collar which is held in an axial direction relative to the internal body by a spring. A bezel ring having a plurality of receiving tabs is mounted in the support collar, the tabs on the bezel ring in the support collar engage tabs on a mounting plate of each nozzle assembly, causing compression of the spring and resulting in a clamping of the mounting plate between a bottom surface of the internal body and the bezel ring.

Abstract: A soldering/desoldering apparatus has a handpiece with a handgrip portion from which a hot air tube extends, a vacuum pickup tube which extends through the handgrip portion and hot air tube, one end of which has a suction cup mounted thereon and an opposite end of which is connected to a flexible vacuum line. Furthermore, an adjustment knob for axially shifting the vacuum pickup tube is provided on the handgrip portion and the vacuum pickup tube is resiliently displaceably supported relative to a displacement mechanism formed by a slide rod fixed to an inner wall of the handgrip portion and a rack member slidably disposed on the slide rod and geared to the adjustment knob. The pickup tube is fixed to a slide bracket which is slidably disposed on the slide rod between the ends of the rack member and between a pair of coil springs which act to position the slide bracket in a neutral position between the ends of the rack member. Additionally, nozzles having a fixed vacuum pickup extension can be used.

Abstract: A nail-like fastener having a substantially rectangular washer adapted to permit overlapping vertical stacking of a number of fastener/washer assemblies for use in a fastener driving apparatus of the type including a piston. The washers each include two substantially U-shaped recesses or cut-outs disposed one each near the midpoints of the top and bottom washer edges, such that the bottom fastener of a stack may be fired from the driving apparatus without disruption of the remainder of the stack.

Abstract: A cartridge-type powder actuated piston tool with automatic cartridge feed by gravity and manual fastener feed. The tool is designed specifically for the setting of fasteners to secure insulating board to ingot mold walls.
