Title: Dewar filling purging and draining systems
IPC: F17C6/00
Filed: 1972-11-23
Abstract: 1382448 Charging cold liquefied gas containers PARKER-HANNIFIN CORP 23 Nov 1972 [7 Jan 1972] 54244/72 Heading F4P A system for transferring liquefied nitrogen from a supply dewar vessel T-1 to a receiving dewar vessel 1 includes a fill conduit 14 having a solenoid-operated fill valve SV-1, a vent conduit 16, downstream of valve SV-1, having a solenoid operated vent-valve SV-2 and terminating in a heater 11, the valves SV-1, SV-2 being controlled by pressure sensors PS, PS-1, PS-3, so that sensor PS responds to a predetermined maximum pressure in the vessel 1 to close the fill-valve SV-1 and open the vent valve SV-2, and either sensor PS-1 or PS-3 responds to a predetermined lower pressure to close the vent valve SV-2 and open the fill valve SV-1. The supply vessel T-1 has a build-up circuit comprising a vaporizer HX-2 and a solenoid operated valve SV-3 controlled by a pressure sensor PS-2. The pressure of liquefied N 2  entering the vessel 1 is controlled by passing a portion of the liquid in conduit 14 through heater 11 and returning it via an ejector ES-1. The quantity of liquid passing through heater 11 is regulated by a valve TCV-1 controlled by a temperature probe TP-1. The pressure sensors actuate the valve solenoids via a D.C. resistor-transistor logic circuit. The vessel 1 may be initially drained via a hose H-2 and line 10, then the control circuit is set to " FILL ". This causes valve SV-3 to open until the build-up pressure reaches 80 p.s.i., valve SV-3 then closing and the ventvalve to open until the vessel pressure drops sufficiently to actuate sensor PS-1 if the vessel I is empty, or sensor PS-3 if the vessel 1 is partialled filled and a first level-sensor LS-1 is covered with liquid. This causes valves SV-2 to close and SV-1 to open provided the build-up pressure of 80 p.s.i. has been reached and the valve SV-3 has closed. If the vessel pressure rises significantly above that set by the probe TP-1, sensor PS closes valve SV-1 and opens valve SV-2, until PS-1 or PS-3 are again actuated. When the top level sensor LS-3 is triggered the fill valve SV-1 is closed and valve SV-2 opened. A shut-off valve SOV may now be closed and the hose H-1 drained through the vent-line 16. The vessel 1 may be purged with gaseous N 2  before filling by actuating a switch on the control circuit which prevents vent-valve SV-2 opening, while the build-up circuit is operative. Valve V-5 in branch line 17 is opened and gaseous N 2  from heater 11 passes through hose H-1, vessel 1 and is vented via valve DV, hose H-2, valve V-3, and line 18. Alternatively, hose H-2 may be connected between connectors C-2 and 5 and valve V-4 opened. The supply system may be mounted on a vehicle whose silencer box is utilized as the heater 11, the system being used to supply the inerting system on an aircraft. The vented gases are passed through the heater 11 to prevent cloud formation.

Title: Method of making electrical connections and electrical connectors made thereby

Filed: 1971-11-29
Abstract: 1340756 Two-part couplings COMPAGNIE FRANCAISE DES PETROLES 29 Nov 1971 [30 Nov 1970] 55370/71 Heading H2E [Also in Division E2] A two-part electrical connector for use both in and out of water, consists of a stationary conductive surface 5a, surrounded by insulation 7,   and a movable conductive surface 1d, forming the annular bottom surface surrounding the aperture of dome 1a, which is surrounded by deformable envelope 2a, and fluid-tight lips 2c. Contained within dome la is a closed rigid sphere 4 containing a gas at lower pressure than the ambient medium. When the movable connector is applied to the stationary surface as at Fig. 1, and pressure is applied downward, optionally assisted by lever 9, vessel 4 is broken, mainly by stud 5b, creating a pressure difference with respect to the ambient medium, and therefore the force created flattens the resilient lip portion 2c on to the stationary surface 6a. A firm electrical contact is thus made between surfaces 1d and 5a, excluding any water previously present. Disconnection is accomplished by release of screw 3 thereby connecting the exterior medium to the interior of the envelope. In further embodiments of the invention, several conductors may be connected using one (Fig. 4, not shown) or several (Fig. 7, not shown) deformable cavities. The vessel containing the gas may be separate from the deformable connector and connected thereto by a connecting duct (Figs. 11 and 12, not shown).
