Abstract: A magnetically operated fail-safe cutoff valve of general application and particularly suitable for down hole fluid well applications is provided having a simple highly reliable valve for equalizing the pressure across the main cutoff valve while closed thereby permitting the same to be opened. All operating components can be either removably installed internally of a tubing string or as a portion of the string itself. In either case, typical wire line operations can be conducted through and past the lower end of the cutoff valve since the flow path of each of the illustrative embodiments provides an unobstructed linear flow path therethrough when the valve is open. The pressure equalizing valve includes multiple flow passages and is controlled by a shrouded annular armature operable independently of a tubular armature controlling the main cutoff valve. The two armatures may be located in either common or separate flux circuits.

Abstract: A cryogenic device and a method for selectively dispensing a jet of gas or a mixture of gas and liquid cryogen particles, that is, single phase or two phase fluid, at the user's option, from a nozzle selected from a range of nozzle sizes. Pressurized liquid cryogen is supplied through an orifice to a nozzle-equipped expansion chamber also connected to a pressure regulated source of gas. A valve-controlled passage venting to the atmosphere from the expansion chamber is normally closed but, when open, is effective to reduce the chamber pressure by a major fraction of 1 psig provided the gas flow from the pressurized gas source is interrupted. The single phase gas jet dispensed in the non-venting mode substantially instantly converts to a stable two phase jet of gas and liquid particles irrespective of which one of the nozzle sizes is then in use.

Abstract: Apparatus and method for dispensing a jet of cryogenic coolant selectively in single gaseous phase and in dual gaseous and finely divided liquid phase from a self-pressurizing source of heat saturated liquid coolant. The coolant is stored under constant pressure and in a heat-saturated condition and, when needed, is partially expanded into an expansion chamber equipped with a coolant jetting orifice and a venting orifice regulatable to control coolant flow from the jetting orifice in single or dual phase. The liquid coolant is conveniently stored in a hand-held dewar flask equipped with a pressure relief valve and utilizing a relatively long, small bore passage as the coolant jetting orifice.
