Title: Process and apparatus for cryogenically cleaning residue from containers and intermediate bulk containers designed for cryogenic cleaning
Inventor: POPP JAMES
IPC: B08B9/20
Filed: 1997-02-12
Abstract: A method and apparatus for the cleaning of residue from the surface of a container where the method comprises cooling the container and residue adhered to the container surface to a low temperature, substantially embrittling the residue, fragmenting the residue, separating the residue from the surface of the container and removing the residue from the container. The container is placed in an enclosure with an opening in the top of the enclosure to permit access to the interior of the container when a container lid is removed.  The system includes a rotating base to turn the container to facilitate freezing and removal of the residue.          Further, there is a commodity container adapted for cryogenic cleaning having a cylindrical body open substantially the full diameter at the top with an outwardly extending flange and an inner sealing band extending to a height above the top of the flange, wherein the flange and the skirt form an acute angle. On the body sits a lid having a cylindrical side wall depending down and terminating with an outwardly extending flange forming an obtuse angle with the side wall, wherein the lid sits on the open end of the body with the lid flange above the body flange and the sealing band overlapping the lid side wall.  The container has a sealing gasket in the channel formed by the inner sealing band, the body flange and the lid flange with a retaining ring applying a force against the body-flange and the lid flange for sealing against the gasket.

Abstract: A method for inhibiting the formation of clathrate hydrates in a fluid (e.g. natural gas) having hydrate-forming constituents is disclosed. The hydrate inhibitors used in the method are substantially water soluble polymers formed from an N-substituted acrylamide having two nitrogen substituent groups, R1 and R2, where R1 is a hydrocarbon group having from one to ten carbon atoms and zero to four heteroatoms selected from the group consisting of nitrogen, oxygen, sulfur, and combinations thereof, and R2 is a hydrogen atom or a hydrocarbon group having from one to ten carbon atoms and zero to four heteroatoms selected from the group consisting of carbon, nitrogen, oxygen, and sulfur. Alternatively, R1 and R2 may be linked to produce a cyclic ring having ten atoms comprising a combination of between three and ten carbon atoms and zero to four heteroatoms selected from the group consisting of nitrogen, oxygen, sulfur, and combinations thereof. Some examples of such inhibitors include poly(N-ethylacrylamide), poly(N,N-diethylacrylamide), poly(N-methyl, N-acrylamide), poly(iso-propylacrylamide), poly(N-propylacrylamide), poly(N-cyclopentylacrylamide), poly(N-cyclohexylacrylamide), poly(acryloylpyrrolidine), poly(acryloylpiperidine), poly(acryloylmorpholine) and various N-substituted acrylamide copolymers.

Title: Printed-circuit board and method for the precise assembly and soldering of electronic components on the surface of the printed-circuit board
Inventor: BUSSE RALF-DIETER
IPC: H05K1/18
Filed: 1997-03-13
Abstract: The invention relates to a printed-circuit board and a method for the precise assembly of electronic components on a surface of the printed-circuit board. The electronic components are electrically and conductively attached to the printed-circuit board by means of a reflow soldering technique. For this purpose, a printed-circuit board is used that has sections for receiving electronic components on its surface, said sections being at least partially adapted to the outside contour of respective electronic components. The sections, configured as slotted contours or grooves, ensure that the electronic components mounted after the application of solder paste are held in their desired positions prior to the actual soldering process. In addition, the assembled printed-circuit board can be connected to a housing composed of dome-type extensions of an at-least-partly-deformable material. Saidextensions engage with cutouts provided in the printed-circuit board and pass through the latter, and a positive-linkage and/or frictional housing/printed-circuit board connection is established by deformation of the extensions. Further, an overvoltage protection plug for terminal blocks for telecommunications with a voltage surge arrester can be mounted; the plug combines the two functions of "earthing contact" and "fail-safe contact" in one part, and assembly can be achieved at little expense.

Title: Method and system for representing hierarchical time-based data structures and to extract information therefrom
Inventor: HILL RAYMOND
IPC: G06F16/185
Filed: 1997-04-15
Abstract: A method and system for representing hierarchical time-based data structures and to extract information therefrom comprises means to create a container, the container having one or more layers within which data elements are arranged along the container axis and to examine the container to produce virtual static graphs which represent active data elements and their interconnections within time durations represented within the container. The data elements in the container can change between active and inactive states with time and the connections between data elements can also change with time and the container represents this information. A set of constraints is defined for the container such that interconnections between data elements only occur between data elements in different layers. Specifically, a data element can only receive input from one or more other data elements which are in lower levels and a data element can only provide output to one or more data elements which are in higher levels. Transitions in a lower layer, representing changes in the active status of a data element, are propagated to each higher layer, such that a higher layer can never have less transitions that a lower layer. Each layer includes a record of which data element outputs are available in the layer at all times. When a request for information relating to the active data elements and their interconnections within a specified time period is received, the container is examined to produce a virtual static graph representing the minimal set of active data elements and their interconnections with the specified time.

Title: Self-adjusting tooth/adapter connection system for material displacement apparatus
Inventor: RUVANG JOHN A
IPC: E02F3/36
Filed: 1997-06-10
Abstract: An excavation tooth point longitudinally extending along an axis and having a pocket area extending inwardly through a rear end thereof is telescoped onto a nose portion of an adapter structure by inserting the nose portion into the tooth point pocket area.  The inserted nose portion has a tapered side opening therein that is positioned between a corresponding pair of similarly tapered tooth side wall openings.  The tooth point is removably coupled to the adapter nose using an elongated, wedge shaped connector member which is inserted, small end first, through the generally aligned tooth and adapter openings.  An internal passage longitudinally extends through the large connector member end and receives an inner portion of a force exerting member which compresses a spring within the passage, the spring in turn resiliently biasing an outer portion of the force exerting member into abutment with an interior surface portion of the tooth. The compressed spring, via the force exerting member, maintains the tooth point in an axially tightened orientation on the adapter nose, and automatically tightens the tooth further onto the adapter nose in response to tooth/adapter interface wear that would otherwise cause undesirable "play" between the tooth point and the adapter nose portion.  The connector member may be removed by pushing the force exerting member further into the connector member passage, rotating it, and then releasably locking it in this retracted position using a cooperating pin and slot structure on the connector and force exerting members.

Filed: 1996-03-08
Abstract: L'invention porte sur l'identification du fondement moléculaire du syndrome du QT long acquis. Plus précisément, l'invention a établi que le gène HERG est associé au syndrome du QT long. On a démontré que HERG encode la principale sous-unité du canal 1Kr. On a découvert que le fait d'accroître les concentrations extracellulaires de K+ a pour effet paradoxal d'augmenter le courant centrifuge de ce canal. Le fait d'augmenter les concentration extracellulaires de potassium chez les patients, en particulier chez ceux qui reçoivent des antiarythmiques ou d'autres médicaments qui peuvent induire une arythmie cardiaque ou chez ceux qui sont atteints de la forme héréditaire du syndrome du QT long, a pour effet de réduire la probabilité de développer un syndrome du QT long et des torsades de pointe.
