Abstract: A self-stabilizing system to protect sensitive equipment housed in a rack from shock forces emanating from the structure or foundation on which the rack is placed. The system includes a chassis restable on the foundation having an array of four vertical shafts anchored thereon. These shafts extend through bearings fitted in vertical ducts incorporated in the four corners of the rack whereby the rack is slidable on the shafts. Springs interposed between the base of the rack and the chassis or between the top of each shaft and the upper end of the duct in which the shaft is received, act to resiliently support the rack on the chassis and thereby attenuate the shock forces. Secured to the underside of the rack to raise it above the foundation are isolators whose stiffness characteristics are such as to resist rotational motion and to permit lateral motion.

Abstract: An improved pedal bin of the type comprising a removable basket eccentrically suspended about an axis inside a rigid, upwardly opened box provided with a lid pivotably mounted on one upper flange of said box, in parallel relationship with respect to the suspension axis of the basket and wherein opening of lid is achieved by action of a pedal against the bottom of the basket, to swing it around its suspension axis, and thus move upwardly the end of the basket diagonally opposed to the pedal so as to tilt up the lid. In accordance with the invention the pedal forms an integral part of the basket, and the box is provided with an opening giving free access to the pedal from the outside of the box. The basket is suspended about two pivots located in its forward upper part, each pivot engaging a hinge integral to the box. Tilting up of the lid is obtained through a finger integral to the basket.
