Abstract: This Invention provides a compound of the Formula: 1

Abstract: A modular furnace is fabricated from at least one module having a frame, a removable cover mounted to the frame, exterior cover panels on the frame, and an insulated case fastened to the interior of the module. A conveyor assembly extends through the module. A plurality of process zones, such as heating and cooling zones, are disposed within the module. Field replaceable universal blower assemblies are associated with each process zone. The motor shaft in each blower assembly is provided with a sealed bearing in the motor housing. Insulation within each module is held in place by gas permeable fabric covering large vent openings in cover panels to allow oxygen to diffuse out of the insulation rapidly upon start up.

Abstract: A mouse pad support is mounted on a keyboard support that has a keyboard support arm attachable to a fixed structure such as the underside of a desk top, and a tiltable keyboard support platform thereon. A mouse pad support arm is coupled to the keyboard support arm via a rotational swivel fitting with a vertical axis for moving the mouse pad arm and mouse pad support table to any position around the keyboard in a circular arc in a horizontal plane. The height of the swivel fitting is adjustably fixed over a range. The mouse pad arm is kept in a horizontal plane because its rotational coupling to the keyboard support arm is made at an angularly fixed part on the keyboard support arm, such as on a parallelogram linkage associated with setting the elevation of the keyboard platform. The keyboard platform tilts relative to the angularly fixed part, whereby mouse position is independent of keyboard platform tilt.

Abstract: A boroscope viewing assembly allows viewing of the process chamber of a solder reflow furnace. A boroscope is removably supported within a cylindrical viewing port permanently mounted through the furnace housing. Coolant gas is flowable along the viewing port annularly surrounding the boroscope to cool the boroscope. The flow of coolant into the process chamber keeps flux vapors away from the boroscope. A sealing assembly seals the boroscope to the viewing port. The sealing assembly can be a gland fitting on the boroscope eyepiece or a compression sealing assembly. When the boroscope is removed, a plug can be placed in the end of the viewing port to seal the process chamber.
