Patent number: 4570819Abstract: Methods and structures are provided for filling cryogenic flasks such as those used in portable, liquid oxygen therapy systems. A circular baffle plate is disposed within the flask neck near the bottom thereof and is sized to allow a narrow annular opening between the baffle edge and the flask neck wall. The liquid fill line is extended downwardly through the baffle plate, so as to discharge liquid below the plate. The baffle plate functions to provide a gas-liquid separation zone within the flask neck; to provide a radiation shield while liquid is present in the flask; and to provide a gas trap to minimize liquid venting in case of tip-over.Type: GrantFiled: November 30, 1983Date of Patent: February 18, 1986Assignee: Cryo, CorporationInventors: Warren E.

Patent number: 4504739Abstract: Described are methods of filling and emptying radiation shields comprising a container formed of thin flexible material.The method of filling comprises the steps of (a) filling the radiation shield with a gas to form the shield and then (b) replacing the gas with a radiation attenuating liquid.Additionally, when the shield configuration is not entirely filled with radiation attenuating liquid, either deliberately or due to leakage, an overpressure of gas above the radiation attenuating liquid solidifies the shield in its designed dimensional configuration.The method of emptying comprises the step of forcing the radiation attenuating liquid out through one or more outlets by forcing a gas into the radiation shield.Type: GrantFiled: September 28, 1981Date of Patent: March 12, 1985Inventor: John A. Weissenfluh

Patent number: 4485853Abstract: An oil change aid device having a concave collection receptacle formed from a thin circular plastic sheet which is attached to and supported by a heavier plastic strip bent into a cylinder. A slot in the cylinder provides a hand hold to permit readily holding the device in one hand. This device is held in one hand and placed near a drain plug of an oil pan and the drain plug is then loosened through the plastic sheet using the other hand. The plastic sheet captures and contains the drain plug, and also protects the hands, arms and clothing from the drain oil. After the drain plug is removed the device is moved to permit the oil drain into a conventional oil pan and the oil poured from the device into the oil pan to permit retrieving the plug from the device.Type: GrantFiled: February 22, 1984Date of Patent: December 4, 1984Inventor: Curtis R. Gunderson

Patent number: 3933186Abstract: Disclosed is a protective housing unit for a liquid sample container. Basic components include an outer housing member and an inner housing member, which are defined by cylindrical sections. The outer member has an open top, an opening in the side wall, and a bottom which connects to a drain line. Positioned within the outer member is a plate for supporting a liquid sample container, such as a bottle. The inner member has an open top, an open bottom, and an opening in the side wall. Also, the inner member is adapted to fit down into the outer member and to rotate within the outer member. A liquid sample is directed into the container through a fill pipe, which connects to an inlet line and which extends through the top of the inner member and down into the container. During filling, the sample container can be completely enclosed by rotating the inner member to mis-align the side wall openings in each member.Type: GrantFiled: December 3, 1973Date of Patent: January 20, 1976Assignee: The Dow Chemical CompanyInventor: Scheffler, Norman E.
