No. 114,855 Int. Cl. F17c 7/02; F25b 19/00 US. Cl. 137596 2 Claims ABSTRACT OF THE DISCLOSURE BACKGROUND OF THE INVENTION The detector cells in some guidance systems are cooled with gaseous argon. In these systems, the flow of the cooling argon gas is initiated by a squib actuated control with no provision for terminating the flow at the end of the test so that any gas remaining at the end of the test is lost. With such a system, it is necessary to replace the cooling gas supply after each test.
BRIEF SUMMARY OF THE INVENTION According to this invention a refillable argon supply is provided. A solenoid valve in the cooling line to the detector cell permits on/ofi control of argon gas. With the solenoid valve shut off, the supply tank can be refilled through a check valve. The supply tank is refillable at the field level which results in a saving of both time and material.

DETAILED DESCRIPTION OF THE INVENTION Reference is now made to FIGS. 1-4 of the drawing wherein reference number 10 shows a cooling package having a storage tank 12, a filling and discharge manifold 14, a cooling gas input system 16 and a cooling gas discharge system 18.
3,719,206 Patented Mar. 6, 1973 The cooling input system 16 has a connector 22 adapted to be connected to an argon gas supply and a check valve 24 connected to the input 26 of manifold 14 to prevent reverse-flow in the supply line.
The cooling discharge system 18 has a solenoid valve 30 connected to port 32 by means of fittings shown generally at 34. The cryostat 36 for the detector cells is connected to a fitting 38 on the solenoid valve 30. The solenoid valve 30 may be any on/ofi type solenoid valve with the proper pressure requirements. The solenoid valve used was a Marotta Model MV-IOOH.
Gas is supplied to the manifold through a fitting 40 which is secured to the tank 12 by any well known means such as welding. The fitting 40 is secured to the manifold by a bolt 42. A passage 44 through fitting 40 mates with passage 46 in the manifold. An O-ring seal, not shown, surrounds the junction of passages 44 and 46. A pressure gauge 39 is connected to port 41 in manifold 14.
In the operation of the device, the storage tank 12 is filled by connecting a supply line from an argon gas supply to the fitting 22. When the pressure within the storage tank 12 reaches approximately 6000 p.s.i., as indicated on pressure gauge 39, the gas from the gas supply is shut off and the supply line is disconnected from fitting 22. The check valve 24 prevents the reverse flow of gas in the supply line.
When the test is started, the solenoid valve 30 is energized through leads 31 to permit the flow of gas to the cryostat wherein it expands to provide cooling for the detector cells in the conventional manner. When the test is completed the solenoid valve 30 is de-energized, and the flow of gas to the cryostat is shut off. The storage tank can then be refilled for another test if there is insufficient gas remaining for another test There is thus provided a refillable cooling system for the detector cells of a guidance system which results in a saving of both time and material.
