Title: Locking device for tools and equipment
Inventor: KADY DARREN J
IPC: B60R25/042
Filed: 1998-10-26
Abstract: The operating control device (80) can be used on equipment such as hand tools, electronics or fuel pumps. An input device (12) enables the input of user access codes and a readout panel monitors the equipment status. A control member is in communication with the input device (12), readout panel, power source (108), driver member and activation member to prevent operation of the equipment by requiring entry of a user code. The control device (80) can include a programmable timer to communicate with the control member to enable the power to flow from the power source (108) to the driver member for a predetermined period of time. A clock can track time and activate and deactivate the timer based. The communication can be through electrical wires that can be encased in a solid material to make the control member and wires inaccessible. When used directly on a fuel pomp, the control member prevents fuel from reaching the engine without the input of a proper user code. Alternatively, the control device (80) can be a fuel line shutoff valve to prevent fuel from traveling along the line. A solenoid (206) can be used in the shutoff valve to prevent flow of fuel from the gas tank to the driver. A locking device (208) for use on bicycles interacts with the axle (204) connecting the peddles. An engagement disk (236) having multiple ports along its circumference, is unmoveably affixed to the axle. A locking bar activation member engages and disengages a locking bar (210) with the engagement disk (236) to prevent rotation of the axle (204).

Title: Conveyor-belt roller assembly
Inventor: FASOLI LUIGI G
IPC: B65G39/09
Filed: 2000-07-05
Abstract: A conveyor-belt roller assembly secured inside a conveyor-belt roller and onto an inner shaft, preferably used in conveyor-belts used for carrying high loads of material in hazardous environments. The conveyor-belt roller assembly has a stationary anti-lock shield which protects the rotating exterior surface from coming into contact with the outside elements for example debris and machinery. A  dust shield is also position aft of the anti-lock shield to prevent the penetration of small particles and dust into the inner workings of the conveyor-belt roller assembly. The conveyor-belt roller assembly also has deep rings in the load-bearing portion for thermal expansion and contraction as well as heat dissipation. Bridging ribs are positioned across the deep rings to greatly increase the strength and therefore load-baring capacity of the conveyor-belt roller assembly. A tapered labyrinth seal is used so that it can be press locked into position making installation quicker and easier. The main load-baring component and tapered labyrinth seal component are preferably fabricated from a high strength, heat resistant 30% glass filled polypropylene.

Title: Capillary electrophoretic methods to detect new biologically active compounds in complex biological material
Inventor: DUNAYEVSKIY YURIY M
IPC: G01N37/00
Filed: 1998-12-16
Abstract: The present method generally comprises mixing a pro-selected, detectable target with a sample of complex biological material to produce a first, sample/target mixture capillary electrophoresis apparatus.  Subsequently, the first mixture is mixed with a pre-selected, tight-binding competitive ligand (TBCL), prior to produce a second, sample/target/TBCL mixture, for a predetermined optimal incubation period sufficient to allow the TBCL to bind a pro-selected percentage of the available target in the absence of any other ligand. An aliquot of the second mixture is subsequently subjected to pre-optimized capillary electrophoresis, during which the migration of the target is monitored. The presence of a potential new compound is indicated by the increase in the peak area of the unbound target peak and/or decrease in the peak area of the TBCL/target complex peak. A capillary electrophoretic profile of the second mixture is produced, which may be compared to a reference standard. The reference standared typically comprises a capillary electrophoretic profile or migration pattern of the target when mixed with a TBCL in an absence of any other competing ligand under similar, preselected capillary electrophoretic conditions.
