Abstract: A vehicle window assembly including a protective transparent plastic window liner covering the inner side of the glass pane and held removably in place by flexible liner-retaining strips having quarter-round molding portions overlying the margins of the liner and anchor portions that are releasably secured in mounting grooves along the edge portions of the window pane. The anchor portions are integral with the molding portions and are pressed into the grooves past detent ribs that lock the strips releasably in place, to secure the window liner against easy removal by a passenger but permitting removal by service personnel for replacement. The mounting grooves are in elongated window-retaining bars that are positioned against the inner side of the paneand also are removably secured in place for ease of reglazing, having enlarged deformable anchors pressed into locking grooves with restricted open sides forming releasable tongue-and-groove connections for removal by tilting of the bars.

Abstract: A bicycle of the "mountain bike" type having two aligned foldable joints in the frame, a folding handlebar assembly and a foldable pedal. Each of the frame joints is mounted in a gap in a tubular frame member and includes two disks disposed flushly against the ends of the tubular members with smaller plugs fast in the members, and two hinge leaves extending across the gap longitudinally of the frame. A rivet on one side of the joint joins two ears on the leaves to form the hinge axis, and a headed fastener with a hexagonal socket is recessed into the thickened central portion of the upper leaf and threaded into the lower leaf to clamp the leaves together. Interlocking ribs between two ears on the other side of the joint prevent relative pivoting movement when the leaves are clamped together. The handlebar assembly has upper and lower tubular adjustment sections for both upward and forward adjustment of the handlebar, and an angled hinge between these sections.

Abstract: A fluid operable engine has a cylinder in which a piston slides up and down. The cylinder has a cylindrical wall and two end walls. The piston divides the cylinder into two chambers. The piston is hollow, has a cylindrical wall and two end walls, with a rigid tube extending from and through one end wall of the piston through an adjacent end wall of the cylinder so that the interior of the piston communicates with the exterior through the tube. The cylinder has an aperture in each end wall or in its cylindrical wall close to the end walls and the piston has an opening in each of its end walls. A closure member is provided for alternately closing the openings or the apertures as the piston reaches each end wall. The engine is operated either in a positive or negative manner, with fluid being charged into or sucked from the piston or the cylinder. The openings may be closed from within or without and the apertures may be closed from inside or outside. The closure member may be mechanically or fluid operable.

Abstract: A merchandising display system and the method of making its posts and struts, using pre-decorated strip material having surfaces such as polished metal or wood-grained vinyl that are covered by removable protective strips. A plurality of elongated sections of the strip material are bent longitudinally to form side portions of the desired cross-sectional shape, including overlapping portions defining longitudinal grooves, and are secured together by rivets in the grooves. The overlapping portions are formed with aligned slots and aligned countersunk rivet holes which serve as aligning abutments in the assembly process. The protective strips are slit in the grooves for quick and neat removal. The grooves in the posts have slots for receiving tabs of tightening mechanisms in the ends of the struts, each including a base plate that is movable longitudinally of the strut by a screw mechanism. Different embodiments are shown for the base plates and the guiding of the base plates for sliding on the struts.
