  • Patent number: 5480191
    Abstract: A molded plastic drum storage and/or transportation device has an inner wall conforming to a drum to be carried or stored. An outer wall is spaced from the inner wall to create a containment space therebetween. One end of the cart has a recess for collecting spills or overflow from the drum. Apertures in the recess allow fluid to flow into the containment space where it is held until emptied through a drain hole. According to one aspect of this invention, the device is tiltable and has wheels to facilitate transport of the drum. According to another aspect of the invention, the device is stationary and is adapted to store multiple drums in spaced horizontal adjacency and, with a drum spacer, in spaced vertical adjacency.

  • Patent number: 5474205
    Abstract: An improved tank configuration wherein a die is employed to stamp a formed member is disclosed. The formed member may be used as either the top or bottom head for a portable liquid container, and is constructed so that all welding is eliminated in the corner and outlet portions of the container. A trim machine is employed to remove uneven edges from the formed part. By the present invention, a stamped configuration is provided in which a draw formed tank bottom is formed so as to allow complete and full drainage of the tank bottom. The top and bottom heads are finish trimmed to exact dimensions so as to facilitate the assembly of these parts to the shell of the tank.

The side walls which extend parallel to the forklift grooves include a series of depressions adapted to receive and retain the ends of support bars which extend across the cavity of the tray to support a pallet thereon. The upper edges of the support bars are vertically below the upper edge of the side walls such that the side walls block undue movement of a pallet resting upon the support bars. The support bars may include support columns extending downwardly to the bottom of the tray to remove the load from the sidewalls and forklift grooves during use.

  • Patent number: 5205472
    Abstract: A fan coil unit which includes a primary pan disposed in a housing and setting-off therewith opposite first and second chamber portions housing a condensation coil and a fan, respectively; an air passage is provided in the primary pan through which air is directed by the fan whereby condensation formed upon the coil will collect in the primary pan, a series of bolts pass through holes in the primary pan and a bracket for the fan motor to secure the fan motor and an associated fan housing to an underside of the primary pan, each bolt includes a head within the primary pan which would otherwise be subject to the adverse effects of condensation, but the cap in this case is covered by a cover cross bonded in a water-tight fashion to the primary pan thereby preventing condensation from adversely affecting the bolts or equivalent fasteners.

  • Patent number: 5201435
    Abstract: An above ground storage facility for volatile and inflammable liquids which includes a concrete vault formed as a base and cylindrical upstanding walls on or integral with said base. An inner liquid container formed of metal has a metal base resting on ribs of the vault base to space the metal container from the vault base. Cylindrical walls of the liquid container are sealed to and rise from said metal base. The walls of the metal container are spaced inwardly from the inner surface of the vault walls to leave an annular envelope of air around the metal container. A conical roof is secured and sealed to the upper edges of the metal cylindrical walls and the roof has peripheral edges which overlie and are spaced from the upper edges of the concrete wall and the annular air envelope around the steel container.

  • Patent number: 5199276
    Abstract: A fan coil unit as provided which includes a housing defining a chamber within which is located a condensation pan and a fan board with the fan board being reinforced by a reinforcing rib which also functions to removably secure the condensation pan to the fan board. The fan board is also supported in the absence of conventional fasteners relative to a rearmost or uppermost wall of a housing of the fan coil unit to facilitate assembly/disassembly of the components thereof. A groove is also formed along one surface of the condensation pan to serve as a location device for aligning fasteners with associated panel mounts of the housing. The condensation pan is also preferably of a hollow extruded construction and includes a variety of different configured ribs to lengthen the thermal path across internal chambers to thereby decrease/reduce thermal conductivity and associated condensation.
