Patent number: 11772858Abstract: An airtight device includes a container and an airtight cover on the container, and the airtight cover includes a fixing bracket, a door, and a pressuring handle. The fixing bracket has a through hole and a guiding slot, and the through hole communicates with internal space of the container. The guiding slot has adjacent first and second top surfaces, and the second top surface is higher than the first top surface. The door selectively covers the through hole. The pressuring handle pivoted on the door has a first section, a second section, and a rotating axis between the first and second sections, and the first section rotates relative to the second section. The second section receives a force to drive the first section to move from below the second top surface to below the first top surface such that the rotating axis pressures the door.Type: GrantFiled: April 1, 2022Date of Patent: October 3, 2023Assignee: DELTA ELECTRONICS, INC.Inventors: Chia-Hsing Chen, Chiu-Chin Chang, Yan-Hui Jian, Chih-Jui Chen, Chen-Hsiu Lee, Hsuan-Ting Liu, Chin-Lung Liu, Kuan-Lung Wu, Li-Hsiu Chen, Wen-Yin Tsai

Patent number: 5533641Abstract: A locking cover assembly has a cover supporting base containing an opening circumferentially surrounded by a cover seat, and a cover movable to and from a closed position on the base in which the cover engages the cover seat to close the base opening. A cover locking mechanism on the cover includes cover locking levers mounted on the inner side of the cover, and a lock actuator movable through the cover and connected to the locking members for moving the levers between cover locking positions in which the levers are extended to engage the base about the base opening and clamp the cover to the base and cover unlocking positions in which the levers are retracted from the base to permit removal of the cover from the base.Type: GrantFiled: October 12, 1993Date of Patent: July 9, 1996Inventor: Toby Argandona

Patent number: 5121849Abstract: A storage apparatus for storing nuclear waste material. The storage apparatus is comprised of an elongated storage canister suitable for the positioning of nuclear waste material, such as spent fuel rods, therewithin. A canister cover covers one end of the storage canister, and may be maintained in an interlocking relationship with a storage canister. The canister cover may be quickly engaged with a remotely operated handling tool, and because of the interlocking engagement with the storage canister, the handling tool may be utilized to handle and reposition the entire storage canister.Type: GrantFiled: January 12, 1990Date of Patent: June 16, 1992Assignee: U.S. Tool & Die, Inc.Inventors: Frederick J. Ellingson, P. Kent Shaver

Patent number: 4759342Abstract: A cooking utensil having a pan with a bottom wall adapted to be placed on a heating surface, and the bottom pan wall having a food support surface and an open top water reservoir adjacent the food support surface. A lid is also provided to form a closed compartment with the pan. The construction of the pan and lid are such that when the pan bottom is heated to fry a food product on the food support surface, water is simultaneously boiled in the water reservoir to produce steam in the closed compartment.Type: GrantFiled: June 8, 1987Date of Patent: July 26, 1988Inventors: Kendal A. Lee, Terrence K. Lee, Margaret A. Lee

Patent number: 4467936Abstract: The present invention provides apparatus which operates the door of a chamber that is capable of maintaining pressure within the chamber. The invention includes an improved closure for cooperating to move the door among positions in which it confronts the opening of the chamber, seals the chamber and allows access to the interior of the chamber. The preferred embodiment of the present invention includes a driving member and an operating member which have surfaces which cooperate to move the operating member in two separate directions. Movement of the operating member in the first direction secures the door in its position in which it confronts the chamber opening but in which it cannot seal the chamber. Movement of the operating member in the second direction causes the door to be secured against the perimeter of the chamber opening, thus sealing the chamber against fluid flow from between the perimeter opening and the door.Type: GrantFiled: July 15, 1981Date of Patent: August 28, 1984Assignee: American Sterilizer CompanyInventor: Raju T. Makhijani

Patent number: 4242564Abstract: A frost plug immersion heater has improved clamping structure which comprises a clamp element having a base engageable against the inner end of the heater body and a pair of channel-shaped clamping arms narrower than the base extending in splayed relation from opposite sides of the base, with the free ends of the arms initially close enough together so that the heater can be installed straight into a cylinder block core plug hole. A T-shape bolt has a cross arm bar-shaped head which has opposite ends engaging in the arm channels and spreads the clamp arms when a nut threaded on the outer end portion of the bolt shank is tightened against the outer end of the heater body. The cross arm head has a thickened crown area of maximum mass providing a maximum strength portion aligned with the shank of the bolt and the top of the cross arm tapers with diminished mass toward the opposite ends thereof to provide a truss-like reinfocement for the head when force is applied through the bolt shank as the nut is tightened.Type: GrantFiled: November 1, 1978Date of Patent: December 30, 1980Assignee: Budd Canada Inc.Inventor: Willard E. Kendall

Patent number: 4175229Abstract: An automobile engine jacket heater includes a body member having a metal sheathed heating element projecting from the reverse face thereof. An expandable yoke assembly is provided on the reverse face of the body member for securing the heater in an aperture of the engine jacket. The yoke assembly includes a plurality of outwardly divergent wing members and a clamp member movable toward and away from the reverse face of the body member by a single screw operable from the obverse face of the body member for spreading the wing members into engagement with the interior surfaces of the engine jacket after the heater is inserted into the jacket aperture. The screw is loosely journaled in an aperture in the body member of larger diameter than that of the screw threads whereby the screw can be canted to an angle of at least 10 to 15 degrees relative to the face of the body member. The wing members are separately formed and have an enlarged aperture at their inner end through which the screw passes.Type: GrantFiled: August 2, 1977Date of Patent: November 20, 1979Assignee: Canadian General Electric Company LimitedInventors: Joseph B.
