Title: Double walled storage tank systems with enhanced wall integrity
Inventor: SHARP BRUCE R
IPC: B65D90/503
Filed: 1996-03-13
Granted: 2000-05-09
Abstract: A double walled storage tank system has two closely associated discreet walls with a closed communication space therebetween. The system comprises (a) a tank having a main body side wall and attached end walls, (b) a continuous wall of a fibrous reinforced resinous material which substantially follows the contour of at least a portion of the tank and (c) an array of interlocking filament bundles disposed between the tank and the continuous wall. The array has a first face bonded to a tank wall and a second face bonded to the continuous wall. A mid-portion of the array is in a substantially unbonded state to create the closed communication space for leak detection purposes. The strength of the double walled storage tank system is substantially enhanced by the array securely bonded to both the tank wall and the continuous wall and by its own inherent tensile strength.

Abstract: A method of manufacturing a laid-up, bonded and, cured composite part, includes filling a groove on a facing surface of a tool with a foaming, self-skinning sacrificial material and covering the facing surface of the tool with a caul sheet. The tool is heated to cure the foaming material, filling the groove and forming a hard, smooth surface skin on the foam, flush with the facing surface of the tool. A series of plies are laid-up on the facing surface of the tool to form a tool-side skin, and other components of the part are laid-up on top of the tool-side skin plies. An adhesive/resin matrix is coated on or pre-impregnated into the skin plies and the components for bonding/curing to create a rigid integral assembly of the skin and components. A vacuum bag is applied over the laid-up skin and components and is sealed to peripheral regions of the facing surface of the tool around the laid-up skin and components. Air is evacuated from under the vacuum bag to cause air pressure outside the vacuum bag to press the vacuum bag against the components. The adhesive/resin matrix is bonded/cured to transform the skin and components into the rigid integral assembly. The vacuum bag is removed from the facing surface of the tool, uncovering the rigid integral assembly. The tool is fixed in a known position on a CNC machine tool bed to position the facing surface of the tool at a known position for edge routing of the rigid integral assembly by a machine tool. A cutter of the machine tool is guided on a predetermined path around the facing surface of the tool, with the cutter extending into the groove below the facing surface of the tool and cutting a peripheral edge around the rigid integral assembly. After edge routing, the rigid integral assembly is a finished part and is removed from the from the facing surface of the tool.

Title: Liquid dispensing apparatus and method
Inventor: ROBERTS BENJAMIN R
IPC: B24B37/04
Filed: 1998-09-25
Granted: 2003-02-25
Abstract: A liquid dispensing method and apparatus in which liquid is dispensed from chambers, that can be pressure vessels, to a flow circuit. A valve network is designed such that when one chamber functions in a dispense mode of operation another chamber functions in a return mode of operation in which unused liquid is sent back to such chamber so that liquid is continually circulated. The chamber or vessel undergoing the return mode of operation is vented through a valve that is either a pressure regulation valve having a set point of pressure or a remotely activated control valve response to liquid pressure at the point of use. In such manner internal pressure within the chamber or pressure vessel undergoing the return mode of operation is regulated to in turn regulate liquid pressure at the point of use. In case of pressure vessel operation, gas pressure within each pressure vessel can also be regulated in conjunction with internal pressure during the return mode to in turn regulate liquid pressure at the point of use. As a result of such pressure regulation, constant flow rate of liquid through the flow circuit and at the point or points of use can be assured.

Abstract: Buse ou tube utile pour verser du métal fondu, notamment de l'acier fondu calmé par aluminium. La buse est constituée d'un mélange de dolomie calcinée et de graphite liés dans une matrice carbonisée. Les buses ou tubes fabriqués selon l'invention ont une meilleure résistance aux chocs thermiques, et ils résistent à la formation d'oxyde d'aluminium quand ils sont utilisés pour verser de l'acier fondu calmé par aluminium. Ils peuvent dont être utilisés dans un processus de coulée en continu sur une longue durée sans qu'il soit nécessaire d'arrêter périodiquement la procédure et de changer les tubes lorsqu'ils sont bouchés par l'oxyde d'aluminium. Du fait de la résistance aux chocs thermiques, l'étape de préchauffage habituelle, précédant le contact de la buse avec le métal fondu, est nettement diminuée.
