Abstract: An adapter arrangement is provided for connecting the inlet opening of a cold air distribution chute with the cold air discharge opening of a refrigeration unit that is mounted in a opening contained in the front wall of the body of a refrigeration vehicle, characterized in that the forward portion of the chute is collapsed upwardly upon the application of a vertical force thereto, thereby to prevent tearing or damage of the chute. The bottom edge of the chute inlet opening is connected with a weighted horizontal rod or bar that is guided for vertical sliding movement on vertical guide rods that are mounted by brackets on opposite sides of the cold air discharge opening of the refrigeration unit. Each end of the horizontal rod is connected with the associated guide rod by a connecting member that is telescopically slidably connected with the rod.

Abstract: A warning barricade apparatus for restricting pedestrian and vehicular traffic and having an increased ability to minimize dislocation of an associated lighting unit upon vehicular impact, while also facilitating removal of the lighting unit for relocation and battery replacement. The warning barricade apparatus comprises a barricade member, an associated lighting unit, a lighting unit sleeve, and an overlaying member. The lighting unit sleeve comprises opposing retaining wall members, which define a lighting unit retention region.

Following the necessary installation steps, such as connection of electrical wire, the mounting strap may be placed on the mount on which the lighting fixture is attached.

Abstract: The invention is a catalyst composition and process for making and using the catalyst composition. The catalyst composition promotes the combustion of carbon monoxide to carbon dioxide. The catalyst composition includes an effective concentration of Group VIII transition metal oxide, an effective concentration of Group IIIB transition metal oxide, an effective concentration of Group IIA alkaline earth metal oxide, and, desirably, microspheroidal alumina. The preferred Group VIII transition metal oxide is cobalt oxide. The preferred Group IIIB transition metal oxide is lanthanum oxide. The preferred Group IIA alkaline earth metal is strontium oxide. The process is for producing a combustion promotor catalyst of carbon monoxide to carbon dioxide. The carrier for the catalyst is effective in FCC units when used on a support which is other than a mullite-containing support.

Abstract: An electronic assembly having one or more heat producing semiconductor components in the form of a chip or die has improved heat dissipation properties. The semiconductor components are formed into subassemblies comprising one or more of the semiconductor components bonded on opposite planar surfaces to metal lead frames. Each lead frame is bonded to a substrate which is electrically insulating and thermally conductive. The resulting assembly is submerged into a central channel of a heat sink. The channel is adapted to receive the assembly such that the channel walls compressingly engage the assembly. Heat is thereby dissipated from the semiconductor components from both planar surfaces of the component.

Abstract: The present invention relates to a carbon fiber prepreg. The carbon fiber prepreg of the present invention is characterized in that a carbon fiber bundle comprising a plurality of continuous carbon filaments and having a hook drop value of 10 cm or more as the degree of fiber entanglement is impregnated with a base resin mainly composed of a thermosetting resin, and that particles of 150 .mu.m or less in particle size made of a thermoplastic resin account for 20 wt % or less based on the weight of the entire prepreg and distributed at a higher concentration in the surface zone than in the inside. The carbon fiber prepreg of the present invention is good in tackiness and less changing in tackiness with the lapse of time, and can form a composite with an excellent compression interlaminar shear strength (CILS) at high temperature after moisture absorption while maintaining good impact resistance.

Abstract: A filter and frame arrangement, e.g., a HEPA type filter/blower unit, has an arrangement for sealing the filter in place to prevent contaminants from leaking around the filter. A secondary seal, e.g., in the form of a gasket, both holds the filter in place in the unit and also seals the space between the primary seal (e.g., gel seal) and the clean space. An extruded gasket seats into a peripheral recess in the frame. This can be removed when the filter needs to be changed out so the filter can be taken out from below and replaced. Then a replacement seal is installed after the new HEPA filter is in position. The gasket seal is as close as possible to the bottom of the frame, i.e., as close to the clean space, so that possible contaminants are prevented from falling into the space below. Instead of an elastomeric gasket, a spring metal gasket can be used, with caulking.

Abstract: A wellhead safety valve control system for opening and closing subsurface and surface safety valves in a predetermined sequence and certain components used with such control system. Dump valves in both latching and non-latching configurations are utilised within the control system. Embodiments of the dump valve may incorporate a time delay feature to ensure the subsurface safety valve is closed after a desired time period following the closure of the surface safety valve in the event of flowline anomalies. Provision is made for independent closure of the surface safety valve without closure of the subsurface safety valve.

The pocket plate includes strut pockets disposed at angularly spaced positions about the axis. The notch plate includes notch recesses at angularly spaced positions about the common axis and positioned in juxtaposed relationship with respect to the strut pockets. The notch plate includes an inner circumferential rail at a radially inward side of the notch recesses and an outer circumferential rail at a radially outward side of the notch recesses. Torque-transmitting struts are positioned in the strut pockets. Each strut has first and second ears at one edge thereof for enabling pivotal motion of the struts about an ear axis intersecting the ears. The opposite edge of each strut is engageable with one of the notch recesses whereby one-way torque transfer may occur between the plates. Each opposite edge has first and second corners.

Abstract: A method and apparatus for selectively predicting the air flows from a duct system that would be produced by environment conditioning plants. The apparatus includes a measurement duct connected to a blower. A restrictor plate is movably mounted over an inlet to the blower to vary the air flow produced by the blower so as to correspond to the air flow generated by a selected environment conditioning plant. A manometer is connected to the measurement duct and is operable to measure static pressure in the measurement duct when the measurement duct is in air flow communication with the duct system. Performance curves for the environment conditioning plants are used to convert static pressures to air flows.
