Abstract: The present disclosure involves a refuse loading station comprising a refuse packer assembly, a refuse container and a loading dock disposed in front of the packer assembly. The container includes a vertically slidable closure. The clearing member includes a cutter edge for severing refuse, and an inclined refuse deflecting surface located under a bottom edge of the closure when the container is in a refuse loading position. The refuse clearing member includes a mechanism for partially raising the closure in response to movement of the container to a refuse loading position so as to locate the bottom edge of the closure above the deflecting surface. Power actuable mechanism is provided for raising and lowering the clearing member. When the clearing member is raised it contacts and raises the closure, and when the clearing member is lowered it contacts and lowers the closure.

Abstract: An automated refuse container discharge station is disclosed in which a refuse container is emptied such that its volume decreases as an essentially constant function of time. The unloading station includes a support assembly on which a carriage assembly is adapted for longitudinally sliding motion. The carrier assembly includes container opening apparatus at one end and container discharging apparatus at the other end. The carriage assembly also includes apparatus for unlatching a container tailgate portion and releasably securing the container to the carriage. A hydraulic cylinder advances the carriage assembly with respect to the support assembly and hydraulically damps movement of the carriage and container at the end of the advancing stroke. The carriage assembly includes an hydraulic discharge cylinder which may be intermittently advanced into the container. Part of the discharge cylinder is supported by guides carried by the carriage and aligned guides carried by the container.

Abstract: A refuse container is disclosed for use in both storage and transportation of accumulated refuse. The container body is an elongated cylindrical member having a rectangular cross section. The container includes a horizontally hinged tailgate having a vertically slidable portion which opens to admit refuse into the container interior. The tailgate lower edge is provided with a latching means which cooperates with cooperating connector means carried by the container frame. An over-center latching mechanism maintains engagement between the latching means and the connector means and includes a latching yoke which prevents inadvertent unlatching of the tailgate. The second end of the container is generally open and has a transverse bulkhead which is slidable between the container ends. As the container is filled, the transverse bulkhead recedes from the tailgate end and provides a controlled resistance against material being compressed in the container.

Abstract: A method for loading refuse involving a refuse loading station and a refuse container. The refuse container is placed on the loading station and the loading station moves the container into a position adjacent a refuse discharge opening of a refuse hopper. Refuse is introduced into the hopper through a refuse inlet opening, which is spaced from the discharge opening. A packer head is reciprocated within the hopper to displace the refuse through the discharge opening and into the container. A clearing member is positioned for vertical reciprocation across the discharge opening for clearing refuse which may become situated between the container and the hopper.

Abstract: A refuse loading station comprising a refuse packer assembly, a refuse container and a loading dock disposed in front of the packer assembly. The loading dock includes a track arrangement on which is mounted a loading carriage for limited movement toward and away from the packer assembly. The carriage is structured for removably supporting the refuse container. A refuse clearing member is provided for clearing refuse situated between the packer assembly and the container subsequent to said container being loaded. A power actuable mechanism is provided on the loading dock for reciprocating the carriage to shift the container toward the packer assembly to a refuse loading position, and to shift the container away from the packer assembly to a container removal position. The carriage is movably mounted on a weighing mechanism which provides an indication of the weight of the container when the container is in a refuse loading position.

Abstract: A heat exchanger for use in a reversible refrigeration system. The exchanger is divided into a plurality of heat transfer zones containing one or more circuits. Control means are provided to route refrigerant through each zone in a series progression when the heat exchanger is serving as a condenser. The flow geometry is automatically changed when the function of the exchanger is reversed from condenser to evaporator so that refrigerant flows simultaneously through each of the heat transfer zones.

Abstract: A reversible vapor compression system having control means associated therewith for automatically routing refrigerant through the heat exchangers in response to a system mode of operation to produce optimum system performance when the system is called upon to produce either heating or cooling.

Abstract: A process for heating the tubular joints of a heat exchanger assembly to facilitate the creation of a fluid-tight bond between the tubular elements. The joints are positioned adjacent to one or both of the heat exchanger tube sheets and a jet of flammable gas directed into the joint region generally perpendicular to the plane of the tube sheet. The velocity of the gas stream directed at the sheet is high enough to prevent the gas from mixing with ambient air and thus being ignited. Upon impacting the tube sheet, the gas stream is redirected along the sheet, reducing its speed and mixing the gas with surrounding air. A combustible blanket is thus established about the tube joints which is ignited to produce controlled heating thereof.

Abstract: The method and tool of this invention functions to reduce the ends of tubular material, such as oil or gas well drill pipe, particularly pipe having a flared end. The tool consists of a mandrel sleeve having an inner tapered surface, a series of conical rollers mounted in a roller cage within the mandrel so the rollers bear against the tapered surface. With the pipe inserted between the rollers and with relative rotational and axial movement between the pipe and the mandrel, the rollers will engage the surface of the pipe applying a swaging force to the pipe which is increased by the decreasing diameter caused by axial movement of the pipe and rollers along the tapered surface.

Abstract: Apparatus for reducing windage and pumping losses in the transmission section of a centrifugal compressor by reducing the density of the atmosphere in which the transmission gear mechanism operates.

Abstract: A member interposed between the inner and outer casings of a rotary machine which is arranged to hold the casings in concentric alignment with the machine shaft as the two casings undergo transient thermal and pressure growth.
