  • Patent number: 4699270
    Abstract: An electronic component packaging system provides individual structural elements of modules that provide both the strength and the internal structure to mount electrical components such as circuit boards without the use of subracks. The resulting structure provides up to 15 percent more usable space for circuit boards. The modules are constructed as to be easily fixed to one another to form a multiple element modular packaging system.

  • Patent number: 4473121
    Abstract: A pressure regulating and relief valve assembly, such as an assembly positionable in a lower portion of a well casing. The valve assembly has a main relief valve assembly or back pressure regulator that is designed to open when the steam pressure exceeds a first predetermined value. A secondary relief valve assembly is provided to vent excess pressure to a space exterior of the valve assembly when the pressure exceeds a second predetermined value, the second value being higher than the first value. The valve assembly is positionable within a well casing at the bottom of a bore hole between a steam generator and a probe utilizing the steam generator. When the assembly is so positioned, excess pressure is vented to a space between the valve assembly and the inner surface of the encompassing well casing.

  • Patent number: 4452555
    Abstract: An attachment apparatus for releasably attaching a structure, such as a wheel assembly, to a standardized ISO container is disclosed. The ISO container includes standardized holes or openings situated in each corner of the container. The structure to be attached includes holes or openings that are substantially alignable with the ISO openings along the bottom edge of the container well. A locking lug is provided which is carried in the structure openings and releasably engageable with the ISO container openings. The locking lug comprises a shaft having an enlarged end portion which fits through the container openings. When inserted, the shaft is rotatable to a locking position. The locking lug is then tensioned to provide a secure and tight coupling between the structure and the container. The structure to be attached to the container is a wheel assembly having an interface assembly for interfacing with the container wall.

  • Patent number: 4084387
    Abstract: Material is fed into a revolving drum which has an interior configuration, preferably in the form of a helical blade, to convey the material at a controlled rate through the drum. A low temperature gas, such as nitrogen, is introduced into the drum downstream when viewed in the direction of travel of the material, in a liquid state at a controlled rate through a spray nozzle system, thereby continuously exposing the material to the cooling effect of the gas. A portion of the gas is recirculated from the upstream end to the downstream end of the drum. The material is pre-cooled in the upstream portion of the drum. After exiting from the drum, the material may be crushed or impacted and separated.
