Abstract: A field emission display (100) includes a cathode plate (102) having a plurality of electron emitters (124), an anode plate (104) opposing the cathode plate (102), and a bulk-resistive spacer (108) extending between the anode plate (104) and the cathode plate (102). The bulk-resistive spacer (108) is made from an electrically conductive material. The resistivity of the electrically conductive material is selected to remove impinging charges while preventing excessive power loss due to electrical current through the bulk-resistive spacer (108) from the anode plate (104) to the cathode plate (102).

Abstract: A cushion dimensioned to support a seated user is comprised of an outer covering with handles defined by a continuous strap attached to the outer covering. A foam cushion layer is permanently attached to the outer covering and a liquid filled pouch is slideably enclosed by the outer covering.

Abstract: A fluid distribution bar, such as for applying a liquid or other fluent medium to a tumbling bed of material to be coated, has concentrically mounted inner and outer tubes in the described embodiment. The inner tube has a plurality of outlets along a length of the tube which are alignable with corresponding openings formed in the outer tube by relative movement of the tubes. A plurality of slidable seals each corresponding to an inner tube outlet are mounted in the interior of the outer tube to overlie and seal the inner tube outlets in a first position, with the relative movement of the tubes unsealing the outlets in a second position for fluid distribution. The described embodiment uses seals comprising an elongated flexible resilient sealing strip mounted at each end in apertures formed in the outer tube such that the flexible strips are elastically deformed to slidably bear against the exterior surface of the inner tube for a good sealing engagement.

Abstract: A water chair which is particularly suitable for use by convalescent or geriatric persons and which comprises a frame having a seat portion and a backrest portion, a plurality of bag-like slings secured by their upper edges to the backrest portion, and a water impermeable bag located wholly within each sling. The bag within each sling is partially filled with water and the space within each bag which is not occupied by the water is substantially free of air whereby the bag and its containing sling will function as a cushion which supports and adapts to the shape of a user of the chair. The bag within each sling is secured to and suspended within the sling so that it does not collapse upon itself when partially filled with water.

Abstract: A chair is disclosed, with a plurality of water bags on the chair serving as the cushion on the back support. The bags are layered down along the back support. Each bag is supported in a sling whose upper margin is attached to the back support. The seat cushion of the chair is also a water bag.
