Abstract: An improved distribution system for an evaporator. The system comprises an evaporator having a plurality of heat exchange flow paths; and an evaporator distributor operably connecting the plurality of flow paths to an evaporator inlet. The system includes an impingement device having an outlet operably connected to the evaporator inlet and having at least a pair of fluid inlets arranged so that fluid entering through either of the fluid inlets directly impinges upon fluid entering the other fluid inlet thereby providing a churned up fluid to the impingement device outlet. Additionally, the system includes an expansion device having an inlet and an outlet; and a separator having a separator inlet connected to the expansion valve outlet and having at least a pair of outlets. The separator is arranged to divide fluid from the expansion device into several streams and direct those streams to its outlets.

Abstract: A process is disclosed for fabricating a thermal inkjet printhead in which the driving circuitry and heating resistors are incorporated in a single integrated circuit. In the process, a protective cavitation layer, which may contain tantalum, is deposited at the locations of the heating regions over a passivation layer and is then patterned prior to any patterning or etching of the passivation layer. A via is then formed in the passivation layer.

Abstract: A linerless continuous series of pressure sensitive adhesive labels is provided which have on one or more selected portions thereof a series of imagable coatings which may be activated to form colored images or areas. The series of labels include a web having first and second surfaces, with a series of imagable coatings of color formers and color developers on the first surface of the web. A coating of a release material overlies the imagable coatings on the first surface of the substrate, and a coating of a pressure sensitive adhesive is positioned on the second surface of the web. The series of labels are wound or stacked so that the coating of pressure sensitive adhesive contacts the release material to permit individual labels to be dispensed.

Abstract: A protectible form including a base ply having a printable face and a release face, a clear ply secured to the base ply release face by an adhesive, and a boundary cut defining matching selected portions of the base ply and the clear ply, whereby the clear ply selected portion may be removed from the base ply release face and adhered to the base ply printable face in a printing protecting position over substantially all of the base ply selected portion.

Abstract: A detachable stabilized intermodal container dumping apparatus for removable mounting on an intermodal container transport vehicle includes a container support frame having forward and rearward ends, a lower frame section and an upper frame section. The upper frame section is constructed of at least two upper section long sill members and at least two upper section crossbeam members mounted on the upper section long sill members. The lower frame section is constructed of at least two lower section long sill members and at least two lower section crossbeam members mounted on the lower section long sill members. The upper frame section is hingedly connected to the lower frame section adjacent the rearward end of the container support frame along a hinge pivot axis extending generally perpendicular to the longitudinal axis of the container support frame such that the upper frame section may pivot relative to the lower frame section, thus permitting dumping of an intermodal container situated thereon.

Abstract: A refrigerant distributor for use in a shell and tube evaporator has a decreasing cross-sectional area which uniformly distributes refrigerant to the tube bundle within the evaporator shell and operates with a small distributor to evaporator pressure drop.

Abstract: A protective door jamb system integrally connected to a door frame. The door jamb system of the present invention includes both a door stop and jamb cladding each manufactured from an extruded plastic product such as hollow rigid plastic, cellular plastic, granular filled plastic or fiber filled plastic. The door stop and jamb clad are each designed to attach to a door jamb substrate through compression deflected fingers. The door jamb system of the present invention may also include a weather strip to ensure a weather-tight seal of a door when the door is closed into the frame. The jamb clad of the present invention covers the recessed portion of the door jamb substrate adjacent the jamb to completely cover the substrate and thereby increase both the structural and aesthetic integrity of the frame.

Abstract: A rail car truck side frame for use in a frame brace truck which has stabilizing cross braces extending between the side frames. The side frame has a top compression member and a bottom tension member which are joined by upwardly and outwardly slanted end walls. Each side frame has a pedestal horn spaced from each end wall. There is a bracket assembly at the lower end of each wall for use in mounting a cross brace. Each bracket assembly includes a three-walled channel mounting bracket, with one wall having an opening therein for the mounting of the cross brace. There is a base plate welded to an outboard side of the side frame and having a first portion welded to an upper edge of the channel mounting bracket for providing support therefor. A second portion of the base plate is welded to the side frame pedestal horn. There is a support plate welded to an inboard side of the side frame adjacent its unit guide pocket and welded to the base plate for providing support therefor.

Abstract: A curb for a rooftop air conditioning unit. The curb comprises: a frame having side walls and end walls arranged in a generally rectangular shape, and a generally planar portion overlaying a portion of the frame. The planar portion includes a first layer providing structural support, a second layer providing a sound barrier, and a third layer provides a heat energy barrier.

Abstract: The position of a slide valve in a screw compressor in a refrigeration system is controlled using a gaseous medium sourced from two or more sources of such fluid, both of which are in open flow communication with the slide valve actuating piston when the slide valve load solenoid is open. Preferred gas sources are a closed compression pocket in the working chamber of the compressor and the discharge passage downstream of the compressor's working chamber. Gas at sufficiently high pressure is available whenever the compressor is operating to ensure that the compressor will load under all conditions within the compressor's operating envelope.

Abstract: An air inlet and damper arrangement. The arrangement comprises a system housing with an external wall having a fresh air inlet; and an inlet air enclosure located within the system housing adjacent the external wall and arranged about the air inlet. The enclosure has an aperture connecting the interior of the enclosure with the interior of the system housing; and a damper sized to cover the aperture and pivotable within the small enclosure between a position covering the aperture and a position uncovering the aperture.

Abstract: A method of controlling fans in a rooftop air conditioning unit. The method comprises the steps of: determining a measure of compressor operating capacity; calculating an indoor fan speed as a function of that capacity; maintaining a fixed relationship between the indoor fan speed and an outdoor fan speed; and controlling the indoor fan in accordance with the calculated indoor fan speed.
