Abstract: An electrophotocopy machine has a web of copy paper that is stored on a supply reel in the machine. A pair of initial feed rollers draws the web off the supply reel and feeds the web past a knife that cuts the web into copy sheets of suitable length. The feed rollers are driven by a gear that is connected to a motor and is mounted on and carried by a lever. The lever engages the carriage in its home position to drivingly connect the motor to the feed rollers through the lever-carried gear. A spring biases the lever against the carriage so that the drive connection to the feed rollers is broken when the carriage leaves its home position.

The tracking surface includes a minimum length long enough to provide point contact with the tread surface at opposite ends of the tracking surface length. The tracking surface has an arc whose radius is such that at least two point contact between the sensor tracking surface and the tire surface may be effected. This abstract is not to be taken as a complete position or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

Abstract: A novel fishing lure is provided, which in one embodiment comprises a substantially cone-shaped tube, said tube being of larger diameter at its anterior portion and having a multiplicity of apertures in the sides thereof. The apertures allow sand to be retained within the tube when the lure is cast through the air and further allow said sand to be dispersed from the tube when the lure strikes water.In a second embodiment, the fishing lure comprises a substantially tubular body having a posterior portion and an anterior portion wherein the posterior portion weighs more than the anterior portion. The lure further comprises means at the anterior portion for attaching the lure to a leader, and means at the posterior portion for attaching the lure to a hook.

Abstract: A trailer suspension and chassis suspension for resisting deflection of tracking of a wheel and including at least one pair of Y-shaped wheel frames each of which has a wheel axle projecting from the joined ends of two diverging frame members, longitudinal pivots joining the other ends of the frame members to the chassis and a leaf spring between each Y-frame and the chassis and secured to the Y-frame, the leaf spring ends being in longitudinal slidable abutment with abutment means on the chassis.

Abstract: A method and apparatus for improving tire uniformity with respect to radial force variation and free radial run-out is disclosed. The method comprises continuously rotating the tire about its own rotational axis under a constant normal load, measuring the variation in the forces generated in the radial direction around the circumference of the tire tread, grinding either or both tread shoulders to correct excessive variation in the radial forces, measuring the variation in the free radial run-out of the tire tread around the circumference along both shoulders and the centers thereof, and grinding either or both shoulders and/or the center of said tire tread to correct excessive variation in the free radial run-out of the tire.
