Abstract: The present invention provides improved paving vehicles for following a supply truck for use in paving asphalt roadways. The paving vehicles of the present invention need not be transported on a trailer, and are capable of traveling at low or relatively high speeds on their own. This is accomplished through the use of novel chassis and propulsion systems having two rear axles, with each axle coupled directly to its own hydraulic motor, such that each of the two hydraulic motors provides power to one axle. Embodiments of the invention also include reciprocating conveyor apparatus and methods, such that the conveyor apparatus may be moved to a lowered position to receive the gravity discharge of materials from a hopper and supply truck during a paving operation, and moved to a raised position in order to provide a wide margin of ground clearance when driving the paving vehicle, or loading or unloading the paving vehicle from a trailer.

Abstract: A floor cleaner including a base movable over a surface to be cleaned, a suction nozzle provided on the base having a suction inlet, a body portion having a fluid dispensing member selectively removable from the body portion, the body portion being pivotally mounted to the base movable between an upright storage position and an inclined floor cleaning position, a suction source in fluid communication with the suction nozzle, and a reservoir configured to provide solution. The fluid dispensing member includes a grip, a dispensing nozzle in fluid communication with the reservoir, and an actuator. The fluid dispensing member is configured to deliver solution from the reservoir through the dispensing nozzle upon user actuation of the actuator, independent of function of the base and body of the floor cleaner.

Abstract: An electronic door lock system includes a gasket system for protecting electrical and mechanical components from exterior water and air. A lock portion may include a gasket, a circuit board, and a plate disposed between a first and second housing. The gasket includes an L-shaped perimeter that wraps around a first side and perimeter edge of the circuit board. The plate compresses the gasket perimeter against a ridge on the first housing to form a seal around the circuit board.

Abstract: A door lock system includes an escutcheon with a keyless cylinder handle. A locking block is disposed in the handle cylinder and spring biased to a locked position to prevent removal of the handle. The locking block may only be moved to an unlocked position by accessing a lock spindle extending through an opening on a rear side of the escutcheon mounted to the door.

Abstract: A door lock system may include an outer spindle operatively connected to a disc with a larger diameter than a diameter of the outer spindle. The disc may include an opening that slidingly receives a lock spindle along a lock axis configured to engage a lock body. The lock spindle and the spindle opening may have complementary shapes and sizes such that the lock spindle is rotationally coupled to the disc about the center axis. Torque may be transmitted from a handle to the disc and from the disc to the lock spindle via the opening.

Abstract: A lock portion of an electronic door lock system includes a first housing and a second housing secured to a backplate of the first housing. The second housing is secured to a first surface of the backplate and only accessible from a second surface of the backplate. One or more wires are secured to the second housing in a service loop and connected to an actuator within the second housing.

Abstract: A door lock system includes a toolless handing assembly that selectively sets a handle in a left or right home position. The handing assembly may cooperate with a disc and a spring that biases the disc to a default position. The disc may be rotated in a first direction to set the disc in a first home position. A catch may engage the disc to retain the disc in the first home position. The catch may be released to return the disc to the default position and the disc may be rotated in a second direction to set the disc in a second home position, opposite the first home position.

Abstract: A door lock system that adjusts to doors of different thicknesses. The door lock system may include self-adjusting spindles that engage and center a lock body in a door. The spindles may exert equal and opposing forces that center the lock body within the door and align the lock body with a latch.

Abstract: A scheduling system and method are provided. The system and method provide a mechanism for a customer to schedule appointments directly with healthcare providers which is not presently possible since each healthcare provider may use a different practice management system that has different formats and protocols.

Abstract: A system for characterizing manual welding exercises and providing valuable training to welders that includes components for generating, capturing, and processing data. The data generating component further includes a fixture, workpiece, at least one calibration devices each having at least two point markers integral therewith, and a welding tool. The data capturing component further includes an imaging system for capturing images of the point markers and the data processing component is operative to receive information from the data capturing component and perform various position and orientation calculations.
