Patent number: 6189579Abstract: A pipe is connected to a panel of a plasma display panel. Non-porization type getters are arranged in the pipe. The panel, getters, and a portion of the pipe located between the panel and the gatters are heated. The inner space of the heated panel is evacuated through the heated pipe. After evacuation, the heating is stopped and the panel is cooled. A discharge gas is introduced into the panel through the pipe. The impurity gases contained in the discharge gas are absorbed and removed by the activated getters which is actavated by the heat. During the evacuation, impurity gases are not absorbed in the inner wall of the heated portion of the pipe. Therefore, no impurity gases are mixed to the discharge gas whose impurity gases are absorbed by the getters. Therefore, no impurity gases are introduced into the panel. After the panel is filled with the discharge gas, the pipe is cut and sealed.Type: GrantFiled: May 17, 1999Date of Patent: February 20, 2001Assignee: NEC CorporationInventor: Yoshito Tanaka

Patent number: 6076568Abstract: A method for inerting a generator in a power station includes flushing the generator in a rapid manner which is favorable in terms of power consumption and is simplified in terms of process technology. Cooling gas which is present in the working state for cooling in the generator is displaced through the use of an inert gas stored in gaseous form, in particular argon. A phase transition from, for example, a liquid to a gaseous inert gas, which prolongs the inerting operation and consumes large amounts of power, can thus be dispensed with. The supply of inert gas can easily be monitored by pressure measurement.Type: GrantFiled: March 15, 1999Date of Patent: June 20, 2000Assignee: Siemens AktiengesellschaftInventors: Helmut Rehm, Klaus Weller, Christoph Lehmann

Patent number: 4896706Abstract: A foldable bag for transporting dry granular powders has a flexible and collapsible skin top, sides and a base with the base a base incorporating a fluidizing port. To transport material the bag is supported to the frame or structure of a container and filled with any dry granular powder. The filling is performed through an orifice in the top portion of the bag. At a destination the contents of the bag are fluidized by providing aeration of the contents through the base of the bag. Once fluidized the contents of the bag are then emptied under gravity or vacuum through outlet ports in the base of the bag. The fluidizing is accomplished a series of channels in the base of the bag with holes for the release of air and with an aeration cloth generally covering these holes. The base of the bag incorporating the fluidizing can be detached from the rest of the bag enabling appropriate recovery or repair of parts of the bag.Type: GrantFiled: October 27, 1988Date of Patent: January 30, 1990Assignee: Amatek LimitedInventors: William J. Tanner, Pawell Baltyn

Patent number: 4895222Abstract: A constant level oiler is provided which is ventilated in such a manner so as to eliminate the need for a large surge chamber. Such an oiler has an advantage in that the problems associated with the fluid surge resulting when the lubricated machine is shut down are eliminated. Furthermore, since a large surge chamber is unnecessary in the present device, the attendant costs associated therewith are also eliminated.Type: GrantFiled: January 23, 1989Date of Patent: January 23, 1990Assignee: Foxport, Inc.Inventor: Ralph M. Hoffmann

Patent number: 4886095Abstract: When filling the inner space (14) of an insulating glass unit (4) with a filler gas, a pressure is exerted during filling on the outer surfaces of the glass panes (12, 13) of the insulating glass unit (4) to be filled. For this purpose, an apparatus is suggested with a device (5) for feeding filler gas and with a device (6), by which air and/or gas can be removed from the inner space (14) of the insulating glass unit, wherein two pressure plates (1, 2) are provided which can be placed, during the filling step, with a preselectable pressure against the outer surfaces of the glass panes (12, 13) of the insulating glass unit (4).Type: GrantFiled: January 15, 1988Date of Patent: December 12, 1989Inventor: Peter Lisec

Patent number: 4848419Abstract: A device for reducing the quantity of oxygen in the space above the filling in a container before closing of the container, in which a vacuum is formed in the space, then a compressed gas is blown into the container in a direction running obliquely to the vertical axis of symmetry of the container and again a vacuum is formed in the space, these steps being repeated if necessary. Valving is provided in the fixed housing within which are formed, coaxially with a central column, an inner chamber and an outer, essentially cylindrical chamber enclosing it. One chamber is connected to a vacuum source and the other chamber to a source of the gas. One head face of each chamber has a plurality of openings at specific angular distances from each other and disposed on an inner and an outer circle respectively. Fixed on the central column is a disc in sealing fashion against the head faces.Type: GrantFiled: December 9, 1987Date of Patent: July 18, 1989Assignee: Calumatic B. V.Inventor: Franciscus A. Damen

Patent number: 4805417Abstract: A tubular body supports a fluid actuated tubular piston connected to operate a coupling mechanism for releasably securing the body to a valve fitting on a refrigerant receiving system. The body encloses components which define a center passage connected to the fitting for first evacuating air from the system and then for directing liquid refrigerant into the system. The passage receives an elongated valve opening member which is fluid actuated to a position opening the valve fitting, and a movable valve member closes the passage to the flow of refrigerant. The fluid actuated coupling mechanism provides for convenient and simple insertion of the tool assembly onto the fitting with no insertion force and also for automatic release of the tool assembly from the fitting after charging is completed. A fluid actuated valve member minimizes the volume of residue refrigerant which vaporizes when the tool assembly is removed from the fitting.Type: GrantFiled: November 5, 1987Date of Patent: February 21, 1989Assignee: Production Control Units, Inc.Inventors: Kim A. Weaver, James M. Jones

Patent number: 4676283Abstract: An apparatus and method for handling carbon dioxide and excluding it from contact with the atmosphere while carbonating and storage, transfer, and dispensing of the carbonated beverage. The apparatus includes one or two vessels and a valve assembly for each vessel. Each valve assembly has a pressure relief valve and an outlet tap, which are normally closed to isolate the interior of the vessel from the atmosphere, and a pump for transferring and dispensing air and liquid from or to its vessel, all without bringing the carbon dioxide in contact with the atmosphere.Type: GrantFiled: September 30, 1985Date of Patent: June 30, 1987Inventor: Michael C.

Patent number: 4662411Abstract: Disclosed are apparatus for recovering beverages from cases of defective aseptic packages such as caused by mismarking. The apparatus comprises a plurality of hollow needle pairs which both puncture the packages. One needle of the needle pair supplies air to the package forcing the beverage to exit through the other needle. The apparatus further includes means for advancing and retracting the needle pairs. The apparatus is pneumatically controlled and powered.Type: GrantFiled: May 13, 1985Date of Patent: May 5, 1987Assignee: General Mills, Inc.Inventors: Craig E. Zimmermann, Stanley C. Rustad, Loren J.

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.
