Abstract: A face shield comprising a contoured visor with three-dimensional structures with varying angles along multiple axes for improved protection and user comfort, an adjustable attachment member for easy user adjustment, and head contact area with improved ventilation. Methods of producing optically clear three-dimensional plastic structures with varying angles along multiple axes and tools for said method.

Abstract: A device for lifting an article comprises a housing having a leading edge region in fluid communication with an inner chamber. The leading edge region is arranged to engage a region between an article and a support surface beneath the article. An elongate tubular member, closed at one end, and at the other end, in fluid communication with the leading edge region and the inner chamber. The housing is arranged to provide a retracted position in which the elongate tubular member is held relative to the leading edge region and responsive to an operative pressure within the inner chamber so as to unfurl beyond the leading edge region where the elongate tubular member migrates along the access region toward a deployed position in which the tubular member extends a distance such that opposed ends of the tubular member may be used in lifting the article from the support surface.

Abstract: Disclosed herein is a device for lifting an article comprising a housing having an inner chamber, the housing having a leading edge region in fluid communication with the inner chamber, the leading edge region being arranged to engage an access region between an article and a support surface beneath the article, an elongate tubular member having a first open end region and a second closed end region, the first open end region being directly or indirectly in fluid tight relation with the leading edge region, the elongate tubular member having a first surface in fluid communication with the inner chamber and an opposite second surface, the housing being arranged to provide a retracted position in which the elongate tubular member is held relative to the leading edge region and responsive to an operative pressure within the inner chamber to unfurl beyond the leading edge region to cause the elongate tubular member to migrate along the access region with the second surface in contact with the article and the supp

Abstract: A nestable wheelchair of the type in which a seat portion of one chair can be slid underneath the seat portion of a next adjacent chair, for nesting, and having side frames supporting the seat, the side frames being further apart at the rear and closer together at the front of the chair, and, a rear support frame extending upwardly and downwardly behind the side frame, the rear support frame having a handle at the upper end for pushing the chair, lower bracing frames extending from forward extensions of the side frames to the rear support frame, with their forward width spacing being less than their rearward width spacing, forward wheels mounted on the forward ends of said lower bracing frames, and rearward wheels mounted on rearward portions of the lower bracing frames, longitudinal bars extending parallel to the lower bracing frames at a predetermined height, permitting forward portions of a rearward chair to be inserted beneath the bar of a nest adjacent forward chair, and providing a lifting action so as
