Abstract: A raised and sealed litter tray enclosure appropriate for placement indoors or connected to the exterior of a dwelling. The raised litter enclosure improves ergonomics during maintenance and cleaning by raising the litter tray/s and placing them on ball bearing drawer slides. The sealing of the litter tray to the floor of the enclosure limits odor transport; and for exterior mounted enclosures this seal prevents heat loss. The hinged subfloor allows for angular travel to unseal the litter tray and provides clearance for the subfloor assembly's opening travel.

Abstract: A rectangular microwave resonant cavity applicator comprising two spaced-apart, cavity-containing sections is disclosed for heating a product web. Each section has a planar peripheral lip which faces the other and the sections are spaced apart by a distance "d". The lips have arrays of ferrite segments mounted on their surfaces which serve to limit radiation of microwave energy from the open space between the sections, through which the product web passes.

Abstract: A serpentine microwave applicator for drying aqueous coatings on polymeric webs. Successive waveguides are coupled by enlarged, inverted, rectangular apertures. With such apertures, normal changes in load have minimal adverse effects on energy utilization.

Abstract: A chuck having radially movable jaws and axially extending jaw-operating levers pivotally mounted intermediate their ends to form shorter and longer arms, of which the shorter arms are operatively connected with the jaws, and the longer arms provide counterbalances for the jaws and are in follower engagement with wedge surfaces on an inward flange formation on a sleeve piston in an outer ring-shaped power cylinder which lengthwise is more or less coextensive with the jaw-operating levers.
