Abstract: The front end of the plug of a cylinder lock is covered by a profiled element which includes a key hole whose profiled shape will only permit certain individual keys of a family of keys that can be inserted into the plug also to fit the profiled element. The profiled element includes attachment elements that have U-shaped engagement surfaces which co-act with corresponding engagement surfaces on a front part of the plug. The profiled element can be fitted to the lock in place, by turning the profiled element perpendicular to the plug axis. The profiled-element attachment elements are inaccessible from outside the lock when the cylinder lock is fitted in place.

Patent CA-2273554-C (CA)
Inventor: LI QIMING
IPC: G01V3/20
Filed: 1999-06-02
Granted: 2003-05-20
Abstract: The present invention describes a method and apparatus to control the effect of contact impedance on a formation resistivity measurement during a logging-while-drilling operation. The control of contact impedance is accomplished by maintaining a substantially zero difference in potential between two monitor electrodes positioned on the resistivity logging tool near a current electrode. The tool can employ a ring electrode configuration and/or a button electrode configuration. The ring electrode configuration incorporates two pairs of ring monitor electrodes on each side of a ring current electrode. The button electrode configuration incorporates a monitor electrode, surrounded by a current electrode, surrounded by a second monitor electrode. Insulation gaps are positioned between each electrode to separate the electrodes. A variable current is supplied to the current electrode in each configuration to maintain the same potential at each monitor electrode.  The effect of contact impedance is controlled through maintaining the same potential at each monitor electrode.

Title: A communication network utilizing autonomous servers to establish a communication session
Inventor: RAMEY KENNETH SCOTT
IPC: H04L29/06
Filed: 1999-10-01
Granted: 2009-06-16
Abstract: An architectural model is proposed which enables the breaking of the dedicated bond between voice-oriented peripheral equipment (PE) based resources and the voice call processing services that classically reside in PBXs, Central Offices, and Key Systems. In addition to being able to physically remote voice PE across data networks, this model enables the voice PE to become a shareable, network-owned resource (as per a Distributed Client/Server model) rather than the dedicated, non- shareable resource of a single voice host attached to the network. This places the voice PE in the same league that data resources (eg bridges, routers,...) and server-based applications have always been. Disjoint voice products based upon this proposed architectural model would likewise be able to simultaneously share voice PE resources, thereby enabling equipment concentration and it's corresponding cost reductions at network level, as well as PE-based sparing/redundancy. In addition, a new, more powerful usage paradigm is described for the telephone that resembles that of the PC. Of course, nothing prevents the network from being configured with only a singleton voice client utilizing the various servers. This degenerate case then corresponds to a distributed, but still logically unbundled PBX complete with traditional telephones.

Abstract: An automated analyzer for performing multiple diagnostic assays simultaneously includes multiple stations, or modules, in which discrete aspects of the assay are performed on fluid samples contained in reaction receptacles. The analyzer includes stations for automatically preparing a specimen sample, incubating the sample at prescribed temperatures for prescribed periods, performing an analyte isolation procedure, and ascertaining the presence of a target analyte. An automated receptacle transporting system moves the reaction receptacles from one station to the next. The analyzer further includes devices for carrying a plurality of specimen tubes and disposable pipette tips in a machine-accessible manner, a device for agitating containers of target capture reagents comprising suspensions of solid support material and for presenting the containers for machine access thereto, and a device for holding containers of reagents in a temperature controlled environment and presenting the containers for machine access thereto. A method for performing an automated diagnostic assay includes an automated process for isolating and amplifying a target analyte. The process is performed by automatically moving each of a plurality of reaction receptacles containing a solid support material and a fluid sample between stations for incubating the contents of the reaction receptacle and for separating the target analyte bound to the solid support from the fluid sample. An amplification reagent is added to the separated analyte after the analyte separation step and before a final incubation step.

Abstract: The technical field concerns an aerospace fire fighting safety mechanism and attachments capable of executing smoke expulsion during initial stages of an in-flight fire in a transport aircraft.   The capabilities include smoke expulsion and fire suppression in both visible and the non-visible areas of the aircraft. The method harnesses the air pressure differential of the outside air to expel smoke through the mechanism and its attachments.   During fire landings this same mechanism and its attached nozzles, flexible tubing and valves, is utilized to allow airport fire-fighters the ability to attach fire hoses to the fuselage and inject water-foam from outside the plane, thus protecting the burning passengers without blocking any escape routes. All Airports will not be required to change or purchase new equipment to use this Invention.
