  • Patent number: 5791367
    Abstract: A pressure relief device that is normally closed and that moves into an open condition under certain design parameters which require fluid to flow from a relatively high-pressure chamber within a vessel to a relatively low-pressure atmosphere surrounding the pressure relief device. A plug housing has a throughbore which forms communication between the chamber within the vessel and the outside atmosphere. A plug is positioned within the throughbore. A fusible alloy at least partially fills a void or a passageway which is preferably formed between the plug and the plug housing. In an upset condition, such as an external fire, the temperature of the fusible alloy rises and thereby softens or melts the fusible alloy. As the fusible alloy softens, the bonding and shear strengths of the fusible alloy are reduced. The relatively high-pressure fluid acting upon the plug preferably forces or blows at least a portion of the plug out of the throughbore.

  • Patent number: 5791158
    Abstract: An absorption cooling system generator with an internal fire tube or combustion chamber is disclosed. The fire tube includes at least one radially projecting heat transfer member on its interior surface that interacts with hot combustion gases. A minimum quantity of refrigerant solution is maintained in the generator by a leveling chamber. The leveling chamber is a refrigerant solution reservoir connected to the generator to maintain substantial equilibrium of the fluid levels within the generator and reservoir. The leveling chamber includes a standpipe. When the refrigerant solution level is above the standpipe, solution may flow out of the leveling chamber and the generator to an absorber. If the solution level falls below the standpipe, set at a predetermined level, solution will not flow out of the generator. Thus, the generator will maintain a minimum, predetermined solution level. In addition, a baffle coil tube and a helical baffle provide an improved solution flow in the generator.

  • Patent number: 5788212
    Abstract: A pressure relief device that is thermally triggered by a shaped memory alloy element. The pressure relief device has a valve body with a passageway that is exposed on one end to a high pressure fluid and on another end to a low pressure fluid. A closure element is moveably mounted with respect to the valve body and operates between an open position and a closed position. In the closed position, the closure element preferably prevents communication between the high pressure fluid and the low pressure fluid. In the open position, the high pressure fluid is in communication with the low pressure fluid. The shaped memory alloy element either directly or indirectly interferes with movement of the closure element. The shaped memory alloy element preferably interferes with the closure element to retain the closure element in the closed position. Upon thermal activation, the shaped memory alloy element deforms and allows the closure element to move from the closed position toward the open position.

  • Patent number: 5779085
    Abstract: This invention is a new device that can be used to plug perforations in materials. This plug comprises a cylinder plug with a tapered bore partially extending through the plug from one end. A cylinder pin that is tapered substantially the same as the plug will fit in the plug after installation is complete. A shear flange surrounds the pin so that when the pin is installed in the plug, the shear flange is against a plug flange. The pin is adhered to the plug by means such as a thin layer of epoxy or glue which allows the pin and plug to be handled as a single component. The pin is designed so that while in this position, there is no significant radial expansion of the plug. The pin has a pattern of holes or grooves that extend the entire length of the pin in order to allow for the expansion of any trapped fluids in the bore of the plug. The pin can have a groove along the outer diameter to allow for easier handling of the pin.

  • Patent number: 5771710
    Abstract: The absorption step of a continuous absorption cycle apparatus (refrigerator or heat pump) is externally cooled by an air-cooled thermosyphon having hot end 107 (FIG. 1), air-cooled end 115, and reservoir 123. The absorption step is further recuperatively cooled by internal fluids, in absorber heat exchanger 108 and/or GAX 109. Thus the absorber is highly compact and the cycle is highly efficient. A hotter hermetic thermosyphon can advantageously supply additional cooling.

  • Patent number: 5772497
    Abstract: A motor is disposed above the protective covering or chassis of a movable surface treatment device. Via its vertically arranged power take-off shaft, the motor drives the horizontally extending rotor shafts, on which respectively one rotor cage is disposed on both sides of a gear housing. The rotor shafts are driven in opposite directions, so that one drum mills in the same direction and the other drum mills with opposite horizontal rotary movement. The gear housing is driven in a stepped-down manner via a two-stage transmission by a power take-off pulley disposed on the power take-off shaft. The rotor cages make two superimposed rotary movements. Thus, the treated surface no longer has a grooved appearance, the surface is treated more evenly and better, and finally, no self-driving force acts on the movable surface treatment device. Work safety is thus increased in addition to work quality.
