Abstract: An optical fiber cable comprising a plurality of buffer tubes, binder wrapped around the buffer tubes, a ripcord disposed between the buffer tubes and the binder, and a protective outer jacket covering the buffer tubes. Upon application of a sufficient outwardly directed pulling force, the ripcord rips both the binder and the jacket thereby providing access the buffer tubes and optical fibers therein. The binder is formed of a material which melts or softens when the jacket is formed by an extrusion process so that the binder is thereby incorporated into the jacket. Alternatively, the binder is formed of a material which will adhere to the jacket when the jacket is formed by an extrusion process and is easily torn when the jacket is ripped by the ripcord.

Abstract: A method and versatile device for use-based context security is described. In an embodiment, the versatile device is implemented as a wristwatch. The wristwatch is configured to facilitate a wireless transaction for an authenticated user and is configured to be worn by the authenticated user such that to encircle a part of the authenticated user. Moreover, the wristwatch includes a validation mechanism for controlling use of the wristwatch based on whether the authenticated user continues to wear the wristwatch after initiating use of the wristwatch.

Abstract: Remote tracing from a local data processing node of the execution of a process within an application program running on a remote data processing node in a distributed data processing network. The application program includes its own local trace facility and the nodes communicate by asynchronous messaging via mailboxes. Each node includes process-private interrupt handling means for indicating the presence of a command for the respective process in the mailboxes.

Abstract: A system, method and article of manufacture for automatically inserting object services such as persistence, concurrency, recoverability, security and distribution into binary classes in an information handling system employing object oriented technology, includes the steps of registering a description of a class in a name service context, searching the name service context for a class object referred to as a factory with desired constraints on properties, whether the object is operable in a predetermined operational environment, where the search excludes object services constraints, for classes which are found by the search, first select those classes which already support the object services constraints, create in the operational environment a class object with the desired object services features, and adding a particular object services feature if the original class provide the desired feature, and returning the class object to the caller which can then use the class object to create multiple instances the

Abstract: An energy storage and conversion apparatus (1) comprising a containment (5) defining a vacuum chamber (7), a substantially vertical shaft within the vacuum chamber (7), a stator (11) on the shaft (9), and a cylindrical rotor (13) which, in use, is driven by the stator (11) to store energy as kinetic energy of the rotor (13) and acts with the stator (11) as a generator to release energy, wherein the rotor (13) is supported by the shaft (9) via an end cap (29), positioned at the upper end of the cylindrical rotor (13), which engages the shaft (9). The rotor (13) is suspended from a pin bearing (31) which is attached to an end cap (29). The pin bearing (31) sits in a bearing cup (37) mounted in a damper (39) at the end of the shaft (9). A magnet bearing (43) is provided at the lower end of the rotor (13) to assist in positioning the rotor (13) relative to the stator (11).

Abstract: A method and apparatus for efficiently representing, maintaining and managing a project and enclosed lifecycles in a data processing system used to support a people-oriented work environment. An object-oriented language environment is utilized to represent projects, processes, states, transitions, users, roles, authorities, actors, members and activities as objects. Process, member, and authority objects inherit from project objects. State objects inherit from process objects. Transition objects inherit from state objects. Project and user objects inherit from actor objects.

Abstract: The invention provides a dual lumen vascular access catheter having a main body defining first and second lumens and a connection structure which includes coupling means attaching the structure to the main body. First and second channels extend from the respective first and second lumens for attaching the catheter to equipment, and first and second rotary valves are positioned in the respective first and second channels. The valves include operators rotatable in generally the same plane to operate the valves and to provide a ready visual indication of the positions of the valves.

Abstract: A magnetic support and transport system comprising a plurality of permanent magnets for interacting with ferrous T-bars of a ceiling grid to counteract gravitational attraction. A plurality of rollers maintain an air gap between the magnets and the grid. A remotely controlled electric motor drives at least one of the rollers and thereby transports the system along the T-bars. Opposing pairs of guides maintain alignment of the system with the T-bars. Each pair of the guides is adapted to automatically retract upon encountering transversely oriented T-bars. When used for grid resurfacing and redecorating applications, the system can support a tape dispenser adapted to transfer adhesive pressure sensitive tape to downwardly exposed surfaces of the grid. A modified embodiment of the present invention is adapted to support surveillance equipment.

Abstract: Glass articles are thermally treated in a gas-fluidized bed of particulate material which is maintained in a quiescent uniformly expanded state of particulate fluidization. Heat exchange within the bed with the material of the bed regulates the bed temperature, and the heat exchange is enhanced by engendering agitation within the bed.

Abstract: This invention relates to the extraction of oil shales and tar sands by using a solvent under supercritical conditions at a temperature within 200.degree. C. or its critical temperature in order to effect extraction of kerogen from the sand or shale.In the case of shales considerable heat needs to be applied to the shale before effective extraction can occur and extraction in this case may be carried out at a temperature within the range of 370.degree. to 450.degree. C.

Abstract: The present invention relates to a process for the hydrogenative extraction of coal which comprises extracting finely divided coal at an elevated temperature between 340.degree. and 480.degree. C. with a gaseous solvent and a hydrogen donor, which solvent at the extraction temperature is above its critical temperature, separating the gas phase extract from the solids residue when extraction has been completed and thereafter condensing the extracted products from the gaseous or vapor phase. The coal is preferably finely divided such that 90% of the coal particles pass through a 1.5 mm. mesh screen. The solvent may comprise a number of utilizable solvent components and the solvent selected such that the sum of the reduced partial pressures of the utilisable solvent components is greater than 1 at the extraction temperature.
