The deflector has a front wall with an internal air scoop for channeling air to a refrigeration unit attached to the front wall of the cargo body. The scoop channels air to the refrigeration unit through an opening and grill at the rear of the scoop. The deflector may have an opening in a top wall thereof to permit escape of hot air from the refrigeration unit to the ambient atmosphere. The scoop and its grill at the rear thereof with openings are dimensioned to pass sufficient air required by the refrigeration unit heat exchange coils.

Abstract: A track assembly comprises an inner channel member, an outer channel member and a top plate, through which load bearing rollers selectively protrude An inflatable air bag is between the inner and outer channels for raising and lowering the inner channel. The rollers are attached to the inner channel and are raised and lowered to a recessed state as the air bag raises and lowers the inner channel. An air line fitting at one air bag end passes through the outer channel member side wall to fix the air bag end longitudinally in place. The other end is clamped by two plates sandwiching the air bag end therebetween. One of the clamp plates has two opposing tabs extending therefrom and which engage mating slots in the side walls of the outer channel. As the bag inflates and deflates, the clamp tabs permit the air bag end to ride up and down vertically wherein the tabs ride up and down in the slots. This keeps the bag end longitudinally in place without adding additional fixation components.

Abstract: An electrical connector is for use with a cylindrical member having an electrically conductive coating which can be damaged. The connector comprises a steel stamped ring with a terminal extending from the ring. Three like contacts overly the central opening of the ring and are bent for abutting the received cylindrical member in resilient sliding ohmic engagement regardless of the insertion or withdrawal direction of the member without destructive damage to the member coating. The contacts are relatively stiff to provide vibration resistant engagement with the member. The ring is supported in a slot in a housing to further stiffen the connector and the contact engagement with the member which completes a circuit which if broken is sensed and transmitted as a tampered condition.

Abstract: A retrofit automatic temperature controlling apparatus and kit is attached to a prior art steam-cold water mixing valve assembly to produce mixed cold water and steam as hot water at a controlled temperature. An adjustment screw is added to the prior art valve assembly to limit the displacement of a steam poppet valve which is opened by a retrofitted piston. Cold water is redirected to a retrofit temperature control assembly having a mixing chamber for receiving the cold water. A water and steam receiving conduit terminates in the mixing chamber and has fluid isolated sections for receiving steam and cold water with a sleeve valve member for selectively coupling the steam and cold water sections to the mixing chamber. The sleeve valve member is operated by a temperature sensing device in the outlet hot water chamber. A disc member separates the mixing chamber and outlet hot water chamber with small passages which promote mixing.

Abstract: A plurality of core mounting outer ring members are each rotationally slidably mounted on a corresponding inner ring member having cam surfaces in the outer surface. A rotating drive shaft has radial pistons and rotates the inner ring member by frictional engagement of the pistons displaced by an inflatable bladder. The outer ring member has a first annular array of bores with core gripping balls resiliently urged radially outwardly to grip a core receiving a winding strip thereabout. A second array of bores in the outer member receive larger core gripping balls which freely displace in the bores. Ramp camming grooves are in the outer surface of the inner ring members, the larger gripping balls engaged with the grooves and forced into gripping engagement with the received core when the inner ring member is rotated. The spring loaded balls provide initial friction load between the core and outer ring members so that the ramp balls can operate to grip the core upon rotation of the inner ring member.

Abstract: A dry powder, for example, a medicament for an inhaler, comprises elongated particles with an aspect ratio sufficient to cause the particles to be bound to a preferably metal or non-metallic sheet material substrate at the particle tips by electrostatic deposition and for aligning a plurality of particles with their major axes aligned normal to the, substrate and oriented tip-to-tip. Particles deposited form a low density, high relative void deposition to minimize attractive forces between the particles. This minimizes agglomeration and bonding forces to the substrate facilitating the release of a powdered medicament in an inhaler. Medicament dosages in a substrate pocket are covered by a sealing layer. An embodiment of a drug dosage inhaler substrate and inhaler is disclosed.
