Abstract:
A bracket for stabilizing a cylindrical compressed air tank suitable for scuba diving against a bulkhead of a boat, the bracket having an operating position where the bracket arms are extended perpendicular to the boat bulkhead for firmly holding a cylindrical tank in place while it rests on its base and pivotal arms that move downwardly flush with the bulkhead and parallel to in an out-of-the-way position when the bracket is not in use. The bracket is comprised of two identical components which can be interlocked together adjustably longitudinally in length to accommodate compressed air tanks of different diameters. Each bracket component has two separate pieces that have an interlocking hinge, both pieces of which can be molded so that the entire bracket can be fabricated at low cost.
Abstract:
A self-contained device for the supply of energy to an apparatus (7) driven by gas under pressure, comprises a portable reservoir (1) of cryogenic liquid, and structure associated with the reservoir to withdraw and vaporize liquid from the reservoir and to send it to the apparatus (7). Two circuit portions (2.sub.1, 2.sub.2) incorporate vaporizers (5.sub.1, 5.sub.2) and are delimited between non-return valves (4.sub.1, 4.sub.2) upstream and control valves (6.sub.1, 6.sub.2) downstream. When open, the control valves drive the apparatus (7). The reservoir (1) is of the double wall type (1.sub.1, 1.sub.2), at least one upstream part of the circuit portion (2.sub.1, 2.sub.2) being disposed between these walls (1.sub.1, 1.sub.2). The two circuit portions are in parallel (2.sub.1, 2.sub.2) and the respective valves (6.sub.1, 6.sub.2) are sequentially controlled by a control device (9, 12) which is sensitive to the pressure (P.sub.1, P.sub.2) prevailing in the circuit portions (2.sub.1, 2.sub.2). Preferably, the apparatus (7) is a pump for supplying cryogenic liquid contained in the reservoir (1) to an installation for freezing food stuffs.
Abstract:
This invention includes an above ground gas storage vessel of tubular or cylindrical configuration. A head or cap with threads mating the threads of the tube is screwed on each end of the tube to form a pressure vessel. Each cap contains a passage therein threaded to mate a reducing bushing. The reducing bushing likewise contains a passage which is at least partially threaded. This passage may be capped to prevent gas flow or valve to allow the flow of gas as required. In an alternative embodiment, the cap assembly is inserted into the tube and retained therein. A packing assembly would be used to seal the tube to prevent the escape of gas. A plurality of vessels are secured in a vertical-parallel arrangement using a support structure to increase gas storage capacity while taking up a minimal amount of ground space.
Abstract:
The present invention provides a portable source of high pressure gas that may be used by service or construction workers. A portable high pressure cylinder is filled with liquid CO.sub.2. A triggering device is threadably connected to a fitting on the upper portion of the cylinder, which fitting contains a high pressure press release valve and an over-pressure relief valve. A unitary housing for the triggering device contains all of the other internal working parts, including the push plate, plunger, and other components for a simplistic, easily usable source of pressurized gas. A belt clip allows the workmen to carry the source of pressurized gas with them for ease of use in their jobs.
Abstract:
A fire resistant tank apparatus adapted for transportation and for installation above-ground to receive and dispense a liquid hydrocarbon or hydrocarbons, or the like, comprising a tank assembly having lightweight wall structure defining inner wall structure, and in certain instances outer wall structure, there being primary space between the inner wall structure, and the outer wall structure; first structure on the assembly defining access porting to a tank interior defined by the assembly; a bottom wall defined by the assembly adapted to support the assembly at an installation site; thermal barrier material associated with the wall structure to effectively define a shell about the tank interior; and structure adjacent the wall structure to support a dispenser for the liquid hydrocarbon or hydrocarbons, or the like, that structure may include a platform unit projecting sidewardly adjacent a lower portion of the outer wall structure, for supporting the dispenser in adjacent relation to the side of the outer wall structure. A portable, metallic support plate and berm may be provided for use below the tank apparatus.
Abstract:
An apparatus for cryogenically cooling a sample comprises a sample chamber within which the sample is suspended, and a vacuum chamber enclosing the sample chamber. A cryogenic element forms at least part of the sample chamber and is in spaced-apart relation to the sample. The element is maintained at cryogenic temperatures by a gas cryopump. A sufficient amount of heat-conductive gas is introduced into the sample chamber for placing the sample in thermal communication with the cryogenic element, thereby cooling the sample to cryogenic temperatures.
Abstract:
An apparatus for holding a fluid under pressure, including a container for containing the fluid under pressure and a valve mounted on the container. The container has a passage leading to the exterior of the container, and the valve has an actuator for moving the valve between closed and open positions. A locking device is responsive to movement of the actuator to a position in which the valve is open to lock the actuator against movement that would close the valve. Consequently, the valve is locked in the open position.
Abstract:
A superconducting magnetic energy storage apparatus comprising a cylindrical superconducting coil; a cylindrical coil containment vessel enclosing the coil and adapted to hold a liquid, such as liquefied helium; and a cylindrical vacuum vessel enclosing the coil containment vessel and located in a restraining structure having inner and outer circumferential walls and a floor; the apparatus being provided with horizontal compression members between (1) the coil and the coil containment vessel and (2) between the coil containment vessel and the vacuum vessel, compression bearing members between the vacuum vessel and the restraining structure inner and outer walls, vertical support members (1) between the coil bottom and the coil containment vessel bottom and (2) between the coil containment vessel bottom and the vacuum vessel bottom, and external supports between the vacuum vessel bottom and the restraining structure floor, whereby the loads developed by thermal and magnetic energy changes in the apparatus can be accommodated and the structural integrity of the apparatus be maintained.
Abstract:
A carbon dioxide fill manifold and method for using which is designed to provide a end-user with an uninterrupted supply of carbon dioxide gas, while at the same time eliminating the necessity of transporting individual, conventional pressurized bottles to be refilled. In a most preferred embodiment the carbon dioxide fill manifold includes a fill line valve connected to an atomizer for receiving a fill line and introducing liquid carbon dioxide into the atomizer, liquid cylinder ports provided in the atomizer for connecting a pair of liquid chambers to the atomizer and receiving and storing the liquid carbon dioxide, a gas cylinder port provided in the atomizer for connecting a vapor container to the atomizer and receiving gaseous carbon dioxide generated in the atomizer and a service line valve also connected to the atomizer for receiving a service lien valve and servicing the end user with gaseous carbon dioxide. A pressure actuated valve is also provided in the atomizer for periodically replenishing the supply of gaseous carbon dioxide from the liquid containers responsive to a selected pressure differential across the pressure actuated valve. A pressure relief valve is seated in the atomizer to guard against excessive liquid carbon dioxide system pressure.
Abstract:
An infrared detector assembly (10) of the type used in munition and night vision systems having an RF activated getter (50). Such detector assemblies (10) include a tubular coldfinger (22) surrounded by a vacuum and which supports infrared detector array (26) and related components. In accordance with this invention, RF getter (50) is located remote from detector array (26) and engages an inner wall surface (56) of a metallic dewar housing (14). The RF getter (50) is activated via RF inductive heating directly through the metal dewar housing (14) such that sensitive IR detector components and hermetic braze joints are kept below their critical temperature. As a result, the present invention provides longer vacuum life and greater operational reliability of infrared detector assembly (10).
