Abstract: A receptacle for enclosing low-voltage electronic devices and maintaining the integrity of a vapor barrier. The receptacle includes a base, and four side walls. Each side wall is joined to two adjacent side walls to form a perimeter wall. The perimeter wall is joined to the base and extends from it in a generally perpendicular fashion. The perimeter wall and base delineate a generally rectangular enclosure with five closed sides and one open side. A mounting flange is joined to the four side walls and extends from them in a generally perpendicular fashion. The receptacle is positioned within a wall of a building so as to allow at least one flange direct contact with a structural member. The structural members of the wall and the receptacle are both covered with a barrier film. The barrier film is sealingly attached to the flange. A hole is created through the barrier film within the confines of the receptacle so that a lo-~v voltage electronic device can be mounted in the wall without compromising the vapor barrier of the building.

Abstract: L'invention a trait à un procédé permettant de déshydrater des boues d'un épurateur de convertisseur à oxigène afin d'obtenir un produit de récupération présentant un débit accru lors d'un traitement dans un flux de recyclage. Des boues humides sont combinées avec des scories chaudes de convertisseur à oxygène pour obtenir un mélange scories/boues. Les boues humides confèrent au mélange une teneur en humidité supérieure à 10 % en poids d'eau, et les scories chaudes, qui ont une température inférieure à celle de l'état liquide en fusion, vaporisent l'eau présente dans le mélange et réduisent la teneur en humidité à environ 4 % ou moins en poids d'eau. Le mélange déshydraté présente des propriétés améliorées de débit lorsqu'il est recyclé comme produit de récupération d'élaboration d'acier.

Title: Integrated deethanizer ethylene fractionation column
Inventor: STORK KARL
IPC: C07C7/04
Filed: 2000-03-06
Granted: 2008-04-01
Abstract: An integrated deethanizer and ethylene fractionation column and process for separating a feed stream comprising ethylene, ethane and C3+ is disclosed. A single shell houses a refluxed upper portion and a lower portion of the column. A generally vertical wall partitions the lower portion of the column into a deethanizer section and an ethylene stripper section. The upper column portion is used as the absorption section of the ethylene fractionator. The feed is supplied to an intermediate stage in the deethanizer, and the deethanizer is operated at a lower pressure (and correspondingly lower temperature) matching that of the ethylene fractionation. The design allows the use of one slightly larger column in place of the two large columns previously used for separate deethanization and ethylene fractionation.

IPC: G01R31/26

Abstract: The invention facilitates measurement of IDDQ values which characterize a test device. A current mirror "mirrors" the current flowing from a power supply through the test device, such that the same current flows through a second current path coupling the power supply to an integrator formed by a transistor connected across a capacitor. Application of a first logic signal to the transistor turns the transistor on, causing current flowing in the second current path to bypass the capacitor, thereby discharging the capacitor. Application of a second logic signal to the transistor turns the transistor off, causing current flowing in the second current path to flow through and charge the capacitor. The rise time of the voltage produced across the charg-ing capacitor is proportional to the IDDQ current value which charac-terizes the test device. The invention further facilitates signature analysis of a test device for defects. A plurality of IDDQ reference values are derived, each value representing quiescent state operation of a defect-free copy of the test device. A corresponding IDDQ test value is derived for each IDDQ reference value. Each test value represents quiescent state operation of the test device after application thereto of the test vector which produced the corresponding reference value. The reference values are compared to their corresponding test values and a plurality of scaling factors are derived. Each scaling factor represents a proportionality between one of the reference values and the corresponding test value. The test device is declared to be non-defective if the scaling factors are equal to one another within an error range which is predefined with respect to the respective test values. Otherwise, the test device is declared to be defective.

Abstract: An apparatus for providing a magnetic field in a casting mold to slow and redirect in a controllable fashion the flow of liquid steel exiting from a submerged entry nozzle into the casting mold uses selectable removable ferromagnetic and non-magnetic laminar elements stackable on the ends of core fingers in the vicinity of the poles of an electromagnetic yoke positioned adjacent the mold face. By selecting the type and location of the stackable elements on the ends of the fingers, one can modify the properties of the magnetic field permeating the interior of the mold. Optionally, independent field coils may be provided for energizing selected portions of the magnetic field core structure to provide further magnetic field control without having to remove and replace laminar elements.

Abstract: Oxygen-scavenging compositions comprising an oxidizable metal component, an electrolyte component and a solid, non-electrolytic, acidifying component. When blended with soft, flexible polymeric resins, these compositions exhibit good oxygen-scavenging performance with improved oxidation efficiency relative to compositions containing an oxidizable metal component, an electrolyte, and an acidifying component combined with a more rigid thermoplastic resins. Selection of a thermally stable non-electrolytic, acidifying component is important when melt compounding the compositions into polymeric resins and particularly for extrusion coating applications. The compositions can be used directly as an oxygen absorbent resin melt-fabricated into a wide variety of oxygen-scavenging packaging articles or as concentrates in combination with other thermoplastic resins.

Abstract: A pallet interface system for supporting a Container Roll in/Out Platform (CROP), flatrack or ISO container within an aircraft, such as a C-17 aircraft. The interface system includes two independent, identical interface pallets which are coupled together by flexible cables. The cables have lengths which enable the two interface pallets to be spaced apart a precise distance so as to be able to support a CROP, flatrack or ISO container. The interface pallets are of small enough dimensions and weight such that same can be manipulated by one or more individuals, thereby obviating the need for a crane to be employed to lift the load onto the pallets before the loading process can begin. Each pallet has a plurality of ISO locking assemblies which allow a CROP, flatrack or ISO container to be locked thereto. Each pallet also has a 463L cargo system edge structure which permits it to be locked to the rails within the C-17 aircraft. The pallet interface system also enables combat offloads and permits cargo supporting platforms to be transported to small, austere airfields where cranes and other large material handling equipment are not available. The pallet interface system can also accommodate different lengths of flatracks, ISO containers, etc., with only minor modifications to the lengths of the cables being required, and is adaptable to handle cargo supporting platforms having varying widths.
