The arm rest pivotally supports a control lever which is movable about a fixed axis on the arm rest for actuating a second controlled device and the control lever is positioned so that the forearm of the operator can remain resting on the arm rest during operation of all of the controlled devices. The system is also designed so that the upper portion of the arm rest which has the control lever supported thereon can be pivoted with respect to a lower portion without effecting operation of any of the controlled devices.

Abstract: An embossed gasket for providing a seal between a pair of confronting surfaces has at least one aperture and at least one embossment adjacent the aperture. The embossment defines a cavity, and a filler is disposed in the cavity. The filler prevents the embossment from flattening out when the gasket is compressed between two confronting surfaces, thereby concentrating the sealing effect of the embossment in the zone of the embossment and enhancing the sealing characteristics of the gasket.

Abstract: An elongated extruded strip adapted to be mechanically secured to a slotted sheet-like substrate is provided by extruding an elongated thermoplastic strip having a body portion which includes a rear face having a rearwardly projecting rail and then notching out longitudinally spaced portions of the rail to provide longitudinally spaced teeth. The strip is pressed against the sheet to force the teeth through the slots and heat is applied to the portions of the teeth which project through the slots to form a head or bead on the teeth and thereby mechanically secure the strip to the substrate. The strip is preferably formed to include at least one side support and/or at least one resilient adhesive tape may be used to allow the strip to deform when pressed against the substrate to force the teeth to project further through the slots to insure a tight securement. The teeth may have an arrowhead when the sheet-like substrate is of uniform thickness.
