Abstract: A horizontally adjustable fixture attachment system comprises a main body panel including a first aperture. A fixture for mounting on the main body panel and has a first tenon member with a shaft portion terminating in an enlarged head portion. A locking plate has a horizontally extending first lower slot portion dimensioned to permit the head portion of the first tenon member to pass therethrough, and has a first upper slot portion extending from the first lower slot portion and horizontally dimensioned to receive the shaft portion of the first tenon member in horizontally close-fitting vertically sliding relation therewithin and to preclude passage of the head portion of the first tenon member therethrough. A latching means is mounted on the locking plate for frictional engagement of the head portion of the first tenon member as the shaft portion vertically moves towards the upper end of the first upper slot portion corresponding to the locking plate being vertically moved relative to the fixture and to the main body panel from the unlocked configuration to the locked configuration. The frictional engagement holds the first tenon member in vertically unmovable relation thereby to preclude movement of the fixture and the locking plate with respect to each other. A contact mechanism precludes horizontal movement of the locking plate and the fixture relative to the main body panel.

Inventor: WOLF DANIEL F
IPC: H02P3/12
Filed: 2002-05-23
Abstract: A locomotive monitoring system 100 defines several mutually exclusive operating states for a locomotive. The amount of time the locomotive operates in each state is preferably determined and recorded. This recorded information can then be evaluated with a view towards improving locomotive operations. For example, a plurality of mutually exclusive idle states can be defined and monitored to determine how long a locomotive idles under certain conditions instead of automatically shutting down for the purpose of conserving fuel. In this manner, the sources of lost fuel savings can be readily identified, quantified and addressed. An event log is also provided for chronicling certain operating events of interest over time, such as those relating to the starting, stopping and/or idling of the locomotive's engine.

Abstract: The device described here is utilizing inertial vision of human eye. As the two wings constantly rotate on a pole, at each given time different lights on the wings light up. During wing rotation the right sequences of lights on both wings light up at the right time. The outcome here becomes that for every half rotation (180 degrees) having the right lights on at the right time, an image is produced. A sensor located on one of the wings synchronizes the lights turn-on time so that during rotation of the wings the lights always light up in the same spot. The wings must rotate quick enough in order to keep the flickering to the minimum.

Title: Liposomal encapsulation of chelated actinium-225 and uses thereof
Inventor: THOMAS JAMES LOUIS
IPC: A61M36/12
Filed: 2001-06-15
Abstract: Actinium-225 and other alpha particle-emitting radionuclides hold great promise as potential therapeutic agents for cancer treatment. However, use o f these radionuclides is limited by systemic toxicity resulting from release o f administered radionuclides and radioactive decay products thereof. If the radionuclides are confined to the target cells, efficacy is increased and toxicity is decreased. However, covalent linking of the radionuclides to targeting molecules does not prevent toxicity resulting from the systemic release of alpha-particle emitting daughter radionuclides. The present invention provides targeted delivery of alpha particle-emitting radionuclide s and their alpha-emitting progeny using liposomal encapsulating to prevent th e loss of progeny radionuclides from the targeting vehicle and, therefore, the  tumor site.
