Abstract: A ventilator (10) is disclosed which includes a ventilator intake hood (11), a pressure relief valve block (12), and a nozzle plate (13). The pressure relief valve block includes a field of pressure relief valves (19) positioned within air channels (20). The nozzle plate includes a field of fourteen nozzles (22) which are aligned with an air channel of the block. Each nozzle defines an interior passage (23) which tapers inwardly as it extends outwardly along the direction of airflow. The nozzles accelerate the airflow so that moisture within the air entering the cooled enclosure does not immediately freeze upon the adjoining enclosure to form an ice block.

The lower portion includes a stainless steel, tubular foot (22) having a plastic glide (23) press fitted into its lower end and metal insert (24) mounted in its top end. The metal insert has internally threaded, central channel (25) extending completely therethrough. The insert is threaded onto the bottom end of the threaded stud for threaded vertical movement along the stud.

Abstract: A door control assembly for a door closing an opening in a wall of a refrigerated compartment cooperates with an oblique hinge set to provide an opening and closing force on the door. The door control assembly includes a mounting plate attached to the door and a flange attached to a door frame. A fluidic control mechanism is coupled to a reciprocating arm pivotally attached to the mounting plate and is coupled to a ball stud on the door flange. A cable is also attached to the reciprocating arm and to a post on the door flange. The fluidic control mechanism and cable cooperate to exert counterbalancing forces on the door at various door open positions.

Abstract: An anti-sag hinge (10) is disclosed which includes a mounting flange (12), a strap assembly (15) and a cover plate (17). The strap assembly includes a top flange (18), a bottom flange (19) and a strap (25) extending between the top flange and bottom flange. The strap has an inner surface (30) defines a plurality of raised or serrated edges (30)a and three elongated openings (36). The mounting flange includes a back surface (71) which has an elongated recess (77) with an exterior facing wall surface or floor (82) that has a texture of raised or serrated edges (84). Three elongated openings (87) extend through the mounting flange. The hinge further includes a strap assembly adjustment plate (100) configured to fit against the inner surface of the strap. The strap assembly adjustment plate has three countersunk round openings (102) there through. The mounting flange adjustment plate (101) is configured to fit against the exterior facing surface.

Abstract: A walk-in freezer door system has a doorjamb with sheets of metal covering a body of thermal insulation. A door is mounted to the doorjamb. A deadbolt housing is mounted to the outside of the doorjamb with a deadbolt mounted for reciprocal movement within the housing between a door locked and a door unlocked position. A handle is rotatably positioned inside of the doorjamb from which a shaft extends into the deadbolt housing and into operative association with the deadbolt. A longitudinal portion of the handle shaft is made of a low thermal conductive plastic. A keeper is mounted to the door in a position to receive the deadbolt with the door located within the doorjamb.

Abstract: A reversible handle for a door having left and right door edges includes a grip generally perpendicular to the left and right door edges and spanning between two handle coupling members. The grip is reversibly positionable in proximity to either of the left or right door edges. A handle extension is coupled to the grip by a connector plate that couples a first end of the handle extension to an adjacent one of the two handle coupling members. The connector plate is configured to couple the handle for use with either a left-hand or right-hand door. The handle extension extends away from the connector plate in a direction generally opposite the grip and couples with a door hinge on the opposite side of the door. The grip is symmetrically configured, such that the grip can be positioned for left-hand or right-hand door opening without turning the handle on the door surface.

Abstract: A height adjustable support is provided for supporting food service equipment and the like at different elevations above a supporting floor. The support comprises a floor engaging member such as a leg or caster that has a threaded upright stud and a coupling having an internally threaded tubular wall threaded thereon. The support also has at least one set screw threaded channel that extends through the tubular wall and a set screw sized to be threaded through the coupling set screw threaded channel and into setting engagement with the stud. So constructed the coupling may be inserted into a bottom channel of the food service equipment with the floor engaging member stud threaded therein and set at a selected position thereby setting the equipment height.

Abstract: A panel fastener is produced by forming a casing blank with two coplanar sides unitarily connected together at one end by a bridge, bending the bridge to bring the two sides to a position parallel with each other about a portion of a hook, and fastening together the other ends of the two casing sides thereby rotatably capturing the hook.

Abstract: A panel fastener strike comprises a unitary casing formed with two substantially parallel face plates unitarily bridged together by a strap at one end and formed with two substantially coplanar flanges at an opposite end, and a pin mounted to the two face plates spaced from the casing strap. In manufacturing the strike the face plates are bent from a coplanar orientation to a parallel orientation while simultaneously seating opposite ends of the pin in the face plate mounting holes.

Abstract: A pull handle comprises a bar bearing an internally threaded insert adjacent each bar end, two spaced posts having a channel that is adapted to be mounted flushly to a door and a closed outside that has a collar in which an end of the bar is mounted. Two screws are provided to be threaded into the inserts through the post channels in mounting the posts and bar to the door.

Abstract: A panel fastener is produced by forming a casing blank with two coplanar sides unitarily connected together at one end by a bridge, bending the bridge to bring the two sides to a position parallel with each other bout a portion of a hook, and fastening together the other ends of the two casing sides thereby rotatably capturing the hook.

Abstract: A freezer door handle and lock assembly comprises a pull handle having a mounting end formed with a slot that is adapted to be mounted to a freezer door. A deadbolt is mounted in the pull handle mounting end for reciprocal movement along a path of travel between deadbolt locking and unlocking positions. A manual push bar extends from the deadbolt to the exterior of the handle mounting end through the mounting end slot. Means are provided for locking the deadbolt in its locking position. A strike is also provided for receiving the deadbolt.

Abstract: A panel fastener comprises a unitary casing having two parallel side walls unitarily connected together at one end by a bridge and held together at an opposite end by a tab formed unitarily with one of the side walls. A hook has its mounting end rotatably mounted between and to the casing side walls and has its catch end extending out of the casing. The fastener is made from a casing blank by folding bridges linking two casing sides to a parallel position over a hook and cam assembly and then swagging a tab on an end opposite the bridge over the other casing side.
