Abstract: A lifting fixture includes a housing; a plurality of jaws movable radially in and out of the housing to secure the fixture to a component to be lifted; at least one lifting bail extending from on end of the housing; and a screw mechanism operatively connected to the plurality of jaws for moving the jaws radially between an inward retracted position and an outward locking position. A related lifting and flipping process is also disclosed.

Abstract: A one-piece molded clamp having two portions connected by a living hinge defines cylindrical passages for two pipes and annular grooves for receiving beads on the pipes. A locking tang on one portion engages a mating cavity on the other portion to hold the clamp closed. The pipes pass through apertures in a wall and the clamp is mounted to the wall by a fastener passing through the clamp. Outstanding ribs on the wall hug the outer surface of the clamp to assist the locking tang in holding the clamp closed. A foam seal with a rubber surface layer is compressed between the clamp and the wall to prevent leaks through the wall apertures.

Abstract: A heater core is mounted over an opening in a wall of a heater and air conditioner case and secured by a single spring steel strap having a straight portion extending parallel to the tubes of the core and bearing on the header flanges. The strap has terminal hook portions which engage anchor apertures in the web outboard of the core. The apertures have flanged edges for engagement by the hook portions and the strap is manually flexed for engagement or disengagement of the hook portions during installation or removal of the strap so that no tools are required. One embodiment has a hook on one end of the strap and a snap fastener on the other end. Another embodiment has identical hooks on both ends of the strap.

Abstract: A vehicle heating and cooling system has a distribution duct separated into two channels by a baffle for supplying separate air streams to the passenger and driver sides of the vehicle compartment. Two temperature control doors associated with the heater core and evaporator separately admit an air mix to the two channels for independent control of driver and passenger side temperature. Optionally a single door is used in place of the two temperature control doors so that at the time of manufacture the system can be configured as a single zone system. A rear air discharge opening is provided in one of the channels to supply a duct leading to the rear seat region of the vehicle compartment.
