Abstract: An electrical connector housing of the type having a spring biased housing cover for closing the electrical connector receptacle is provided with a lever actuated latch for holding the cover in an open position against the spring force.
Abstract: A nozzle includes a body, a substantially rectangular foot, air slots and a flow restrictor. The body directs a stream of hot air into the substantially rectangular foot. The foot has a top and bottom surface that includes air slots. The foot also has an outlet across one end for the air flow. A flow restrictor is positioned in the foot, substantially along the outlet to create a back flow of pressure within the foot. The back flow of air causes an even distribution of air across the foot and out the air slots. Thus, increasing radiant heat across the surfaces of the foot.
Abstract: An automatic seam welder for thermoplastic material includes a single piece frame riding on two drive wheels and a caster, the drive wheels being driven by a drive motor through a helical spring clutch. A heat gun is gimbal mounted to the frame and includes a blower, heating element, and shaped foot to direct hot air between overlapped thermoplastic sheets. A thermocouple in the foot directly senses the air temperature and, through a control circuit in a control instrument enclosure, is used to control power to the heater element. A guide wheel, foot rest and air dam are also provided.
Abstract: A recirculating sandblasting device having a generally cylindrical body with a conical blasting medium bin is mounted on a cart and includes a cyclonic separator and a high capacity filter for filtering air drawn in by a blower and motor within a motor housing. A sandblasting head includes a supply line to draw blasting medium from the medium bin and a return nozzle with a resilient bellows connected to a recovery hose for returning laden air to the cyclonic separator in the body.
