Abstract: Multi-jointed and pivoted mounting systems for support of a flat panel video display and/or keyboard tray, incorporating a plurality of pivot points providing for pivotal motion of one or more components about a plurality of vertical and horizontal axes. Support arms having elevational pivot assemblies, including plastic friction washers and gas springs, offer elevational arm control requiring constant and predetermined positioning effort on the part of the video display operator and keyboard operator.

Abstract: An exercise apparatus comprising a foot receiving plate, a pivoting support and a base. The foot receiving plate includes a strap for the user's foot, a ball joint adjacent and on the bottom of its heel end for securing the foot receiving plate to the pivoting support, and a spring connecting the toe end of the foot receiving plate to the pivoting support. The ball joint permits the foot receiving plate to pivot laterally and transversely with respect to the pivoting support, and the spring biases the foot receiving plate towards the pivoting support. Additionally, a removable ball below the toe end of the foot receiving plate allows for radial pivoting. The pivoting support is pivotably mounted via a hinge to the base beneath the toe end of the foot receiving plate, thereby permitting the foot receiving plate and pivoting support to pivot away from the base.

Abstract: A forcing press for simultaneously pressing members onto opposite ends of a central member, such as railroad wheels onto an axle, wherein the press is prestressed by exerting balancing force against opposite ends of the axle prior to pressing the wheels onto the ends of the axle and including mechanism for simultaneously pressing the wheels onto the axle.
