Abstract: A coupling assembly is provided having a first member and a second member. The first member is able to be coupled to the second member by relative movement along a coupling axis. In use, a tension component carries the axial tensile load of the coupling assembly. In order to decouple the coupling without removing the tension component, it is necessary to apply sufficient tensile force to fracture the tension component. Thus the tension component is designed to fracture in to two parts along a single fracture. Advantageously, because only a single tensile component is used, the precision in the set force necessary to decouple the two parts is improved. The coupling assembly is particularly suitable to joining two part of an oil pipeline in order to provide a safety, breakout function.

Abstract: If the pressure in a supply passage drops at a speed greater than a first determination speed in a state in which a first mode for supplying gas fuel to an internal combustion engine is selected, a control apparatus inhibits selection of the first mode. Then, the control apparatus switches from the first mode to a second mode, in energy other than gas fuel is used. In this state, if the pressure in the supply passage drops at a speed greater than a second determination speed, the control apparatus maintains the state in which the second mode is selected. If the pressure in the supply passage drops at a speed lower than the second determination speed, the control apparatus cancels the inhibition of selection of the first mode when it is detected that a manual on-off valve is opened.

Abstract: This invention is a food preparation device used for imparting the flavor of smoke to foods by saturating the food with smoke in minutes, using very small amounts of wood or other smoke producing material, and upon completion of the process the food can be refrigerated, re-refrigerated, or cooked in any manner desired by the user. Efficiency of time and material is achieved by a unique design that allows a minute amount of smoke producing material to be ignited in a small ignition chamber before being transferred to a chamber containing the food in a partial vacuum created by a vacuum/compression pump, and through the unique design of valves and connector pipes the smoke filled chamber containing the food is subsequently subjected to compression by the vacuum/compression pump, thus leaving the food in the chamber smoke saturated within a few minutes of operation with little or no change in temperature.

Abstract: An inertance tube for a pulse tube refrigerator which can be tuned to optimize performance. Apertures in the inertance tube fluidly communicate the inertance tube with a fluid reservoir. The effective length of the inertance tube is changed by alternatively closing or opening the apertures. Changing the effective length of the inertance tube causes a phase shift between the mass flow and pressure waves in the working gas which, in turn, changes the acoustic power. Controlling the phase angle improves Carnot efficiency. The cooling load capacity of the pulse tube refrigerator is a function of the acoustic power.

The collar has the housing in which are located two compression springs with arms which are held against the force of the springs by fusible links.

Abstract: This invention relates to a heat activated shut-off device for gas and liquid flows in fuel supply lines and consists of a housing with a longitudinal void therethrough for fluid passage. A valve seat within the longitudinal void and a spring biased piston slidably carried within the housing when in bearing engagement, will shut-off the flow of fluid. A eutectic metal fuse which is temperature sensitive and fails at a pre-determined temperature extends in part externally of the external surface of the housing and couples with a flow indicator carried adjacent the housing external surface. Coupling of the eutectic metal fuse and flow indicator exposes the eutectic metal fuse at least in part to ambient air. The flow indicator is rotatable upon displacement of the piston. Failure of the eutectic metal fuse results in the uncoupling of the flow indicator that permits the spring to displace the piston into the valve and consequently rotate the flow indicator to another position thereby evidencing shut-off.
