Abstract: A tool for reattaching a leader pin assembly to the data tape of a data tape cartridge utilizes a base that snaps onto the cartridge body. The tool opens the door of the cartridge and the loose leader tape inside the cartridge is laid in an alignment channel. A leader pin is inserted into a set of receptacles over the tape, and a clip is inserted into a pocket within an arm on the tool. The tape is then folded and pulled down over the leader pin and held in the alignment channel with a finger of the user. The arm of the tool, which retains the clip, is then pivoted from a disengaged position to an engaged position. The clip snaps over a center section of the leader pin and the folded tape to form a leader pin assembly, thereby securing the tape in the leader pin assembly.

Abstract: This invention improves the performance and lowers the cost of DC to AC inverters and the systems where these inverters are used. The performance enhancements are most valuable in renewable and distributed energy applications where high power conversion efficiencies are critical. The invention allows a variety of DC sources to provide power thru the inverter to the utility grid without a transformer and at very high power conversion efficiencies. The enabling technology is a novel inverter circuit topology where the DC source is connected directly to the positive bus of the DC to AC converter and where a negative bus is generated from the positive bus with a flyback converter. The inverter power topology does include or require a transformer. The AC inverter output configuration can be either single-phase or three-phase. The AC inverter output can be either utility interactive or directly supply loads.

Abstract: A method and apparatus to monitor the positioning of a tape leader pin in a tape threader block moveably disposed in a tape drive. The' apparatus includes a tape threader block assembly comprising a first circuit having a first coil, a second circuit having a second coil, where that second circuit has an impedance, where the first coil is disposed adjacent the second coil. The apparatus further includes a detection circuit which detects the impedance of the second circuit, where the second circuit has a first impedance when the first circuit is open, and where the second circuit has a second impedance when the second circuit is closed. In the event a tape leader pin is properly releaseably fixtured to Applicants' threader block, the first circuit is closed and the impedance of the second circuit changes. The detection circuit detects that impedance change and provides a signal to a controller indicating that the tape leader pin is properly seated in the threader block.

Abstract: A hazardous materials shipping system for tracking a plurality of packages containing hazardous materials. The shipping system includes a shipment order system configured to record shipping and hazardous materials information, and to issue a tracking number for the package. A package tracking system tracks a path of the package through various delivery vehicles and other facilities. Information on the hazardous materials can be correlated with the delivery path of the package by a hazardous materials database system using the tracking number. Optionally, the hazardous materials database system can make the delivery path and hazardous materials information available to an emergency response team to facilitate containment and cleanup of hazardous materials along the path. As another advantage, the hazardous materials database system can compare the paths of various packages to determine if cross-contamination has occurred.

Abstract: A bearing supports a rotating element. The bearing comprises an inner annular body and an outer annular body about the inner annular body. A bearing surface, which is located between the inner annular body and the outer annular body, supports the outer annular body for rotation about the inner annular body. A cage supports the bearing surface during rotation of the outer annular body about the inner annular body. The cage includes a material that imparts increased flexural modulus that resists deformation during rotation.

Abstract: The present invention discloses a method of separating or distinguishing carbohydrate substances. More particularly the method includes using fluorescent labeling reagents which have a positive charge when bound to a carbohydrate, involves separating the labeled carbohydrate substances, such as by performing electrophoresis to cause differential migration of different labeled carbohydrate substances, or by isoelectric focusing in a pH gradient. The fluorescent labeling reagents are preferably cyanine dyes.

Abstract: Improved photopolymerization initiator systems are comprised of a spectral sensitizer that sensitizes in the ultraviolet or visible regions of the spectrum and an N-aryl, O-aryl or S-aryl polycarboxylic acid co-initiator. The improved initiator systems are incorporated in photo-polymerizable compositions containing one or more addition-polymerizable ethylenically-unsaturated compounds to form compositions suitable for the preparation of radiation-sensitive layers in lithographic printing plates adapted to be imagewise-exposed with ultraviolet- or visible-light-emitting lasers such as argon-ion lasers and frequency doubled Nd:YAG lasers. Such plates are able to effectively meet the dual requirements of very high photospeed and very good shelf-life required in computer-to-plate systems.

Abstract: A peel-developable lithographic printing plate is comprised of a substrate, a hydrophilic layer comprising a polymeric acid overlying the substrate, a radiation-sensitive image-forming layer overlying the hydrophilic layer and a stripping layer that is strippably adhered to the image-forming layer. The image-forming layer is comprised of a photo-polymerizable composition comprising a polymeric binder, a plurality of addition-polymerizable ethylenically-unsaturated compounds at least one of which possesses phosphorus-derived acidic functionality and a photopolymerization initiator. After imagewise exposure of the plate to activating radiation, the stripping layer is peeled from the image-forming layer with only the unexposed regions of the image-forming layer adhering thereto so as to reveal the underlying hydrophilic layer and thereby form a lithographic printing surface.

Abstract: Foamed plastic is applied on a roof substrate by progressively dispensing expandable plastic foam material on the substrate along a path and progressively confining the vertical and lateral expansion of the material along the path and relative to the substrate. Apparatus for applying the foamed plastic comprises a platform having opposite ends and opposite sides having an endless belt supported on the platform for displacement relative thereto in the direction between the opposite ends. The belt is supported above the roof substrate by laterally spaced rails or by tracks on the belt, and a motor is provided on the platform for driving the belt to move the platform along the path. A dispensing gun is supported on the front end of the platform for dispensing expandable plastic foam material onto the substrate ahead of the belt and vertical and lateral expansion of the material is confined by the belt and rails or tracks as the platform moves along the path.
