Title: Valve with fire-resistant seal
Inventor: MAKI ROBERT E
IPC: F16K5/06
Filed: 1999-03-15
Granted: 2001-12-04
Abstract: A valve with fire-resistant seal for use in industrial piping applications. The valve includes a valve body with a valve element therein. The valve is illustrated as a ball valve, but other valve configurations could also be used. A valve stem engages the valve element so that it can be rotated between open and closed positions. A conventional primary seal is used on the valve stem for normal conditions. The valve body defines a body bearing surface, and the valve stem defines a facing stem bearing surface. A thrust bearing is disposed between the body and stem bearing surfaces, and a fire-resistant seal is positioned radially inwardly from the thrust bearing. Initially, the fire-resistant seal is not engaged with at least one of the body or stem bearing surfaces, and the fire-resistant seal has a thickness less than an initial thickness of the thrust bearing. If the valve is subjected to heat such that the thrust bearing is destroyed or damaged, pressure loading on the valve stem forces the fire-resistant seal into sealing engagement between the body and valve stem. At least a portion of the fire-resistant seal is forced into a cavity defined in the body by a chamfered surface.
Patent CA-2268901-C (CA)

Filed: 1997-11-04
Granted: 2006-02-21
Abstract: A method and apparatus for rapid in situ spectroscopic analysis of preselected components of homogeneous solid chemical compositions, especially pharmaceutical products. The apparatus comprises a high-power pulsed laser (10) whose beam is focused on the material (18), typically a tablet or the powder prior to compaction into the tablet, which generally consists of an active ingredient (e.g. a drug) and a filler material (cellulose, glucose, lactose, etc.). The pulsed laser beam vaporizes a small volume of the pharmaceutical product and produces a plasma having an elemental composition which is representative of the pharmaceutical product. The atomic composition of the vaporized material is analyzed with an optical spectrometer (24).      As the temperature of the plasma is sufficiently elevated to cause dissociation of the molecules of the constituents of the pharmaceutical product, the concentration of the active ingredient is obtained by analyzing the atomic concentration of an element which is present in the active ingredient but not in the matrix or filler material, or whose concentration in the active ingredient is substantially different from the matrix, and acts as a tag on the active material. The technique can also be used to analyze inactive ingredients or the presence of unwanted contaminants which consist of elements not normally present in such pharmaceutical products such as trace metals introduced accidentally during processing.

Abstract: An assembly for supporting the floating roofs of tanks for storing liquids, particularly hydrocarbons, comprises a support leg (5), a guide (7) rigidly fastened to the floating roof which it is desired to support, and a locking pin (11). The lower end (16) of the guide (7) acts as a support for the floating roof when the assembly is in the operating mode. In this situation, the support leg (5) has no structural function and may be withdrawn, and the locking pin is installed at the top of the guide (7) coaxial with the vertical axis of the guide, so as to close the orifice via which the support leg passes. When it is necessary to place the roof in the maintenance mode, the support leg is again inserted in the orifice via which the guide (7) passes and the locking pin (11) passes through the orifices (13) of plates (12) which are rigidly fastened to the top of the guide (7), which allows the assembly to be locked. The orientation of the locking pin (11) enables an operator remotely to ascertain the operating status of the floating roof.

Title: Lock mechanism
Inventor: NEWMAN DONALD JOHN
IPC: E05B53/00
Filed: 1998-04-06
Granted: 2006-10-10
Abstract: The invention is concerned with a lock mechanism of the kind having a deadbo lt (9) which is operable by either an inside actuator or an outside actuator. The inside actuator usually includes a turn knob or the like, and the outside actuator usually includes a key operated lock. The lock mechanism includes a gear train (8) through which each of the two actuators is drivably connected to the deadbolt (9). The gear train includes two drive gears (13, 14) which are independently rotatab le about a common axis of rotation, and each is connected to a respective one of the two actuators so as to rotate in response to operation of that actuator. The gear train (8) also includes two driven gears (17, 18) which are united to form a single piece composite gear (16), and ea ch driven gear (17, 18) is cooperable with a respective one of the two drive gears (13, 14). The composite gear (16) is connected to the deadbolt (9) so that the deadbolt (9) moves between operative and inoperative positions in response to rotation of the composite gear (16) . Each actuator adopts a rest position when the deadbolt (9) is in the inoperative position, and neither drive gear (13, 14) cooperatively engages with the composite gear (16) when the respective actuator is in the rest position. Furthermore, the gear arrangement is suchthat the outside actuator turns through 360.degree. to cause the deadbolt (9) to move from one of its positions to the other, whereas 180.degree. rotation of the inside actuator is sufficient to effect the same degree of deadbolt movement.

Granted: 2005-08-02
Abstract: In order to decrease the overall cost of storing large amounts of data, systems have been developed that use a hierarchy of storage devices from fast local disks ( 118) to archival off-line storage (122). Such storage devices (118, 122) may be managed in a hierarchy where data that is accessed only infrequently can be moved to archival storage (122). The present invention relies on a tight integration of a hierarchical storage manager (110) into the I/O system so that remotely stored attributes (112) can be identified and tracked internally to the I/O system just like any other attributes.      Implementations of the present invention may relay on a layered driver model where lower level drivers (104) detect the existence of files with remotely stored attributes (112) and then transfer control for processing I/O requests involving files with remotely stored attributes (112) to higher level drivers (100). The higher level drivers (100) then assume control to finish processing the I/O request.
