Abstract: A venturi spray nozzle having a cleaning fluid manifold with a plurality of fingers extending into a plurality of venturi nozzle channels of an air manifold such that the air manifold educes cleaning fluid from the cleaning fluid manifold and projects it on a surface to be cleaned. The cleaning fluid manifold is centrally positioned in the air manifold and a pressurized source of cleaning fluid is used.

Abstract: An adjustable work table is disclosed comprising a frame having spaced apart sides (6), a horizontal shaft (60) supported between the sides of the frame, and a table surface assembly (10) rotatively mounted to the shaft. Camming angular adjustment means (98, 110) is provided for rotating the table surface assembly into selective angular positions about the shaft. Vertically actuating scissor arms (44, 46) are further provided for moving the support shaft upward and downward whereby providing a vertical adjustment.

Abstract: Method and apparatus for coating catalytic converter substrates with an exact amount of a precious metal. In the course of operation of the apparatus, a hollow substrate to be treated having opposed open ends is transferred from a starting location such that one end is lowered into a dip pan into which has been introduced a predetermined amount of slurry material containing the precious metal. With the one end immersed in the slurry, a vacuum placed on the other end of the substrate draws up the entire charge of slurry from the dip pan to coat the lower portion of the substrate. Thereafter, the substrate is raised from the dip pan. The vacuum continues to operate to cause the coating to be evenly distributed on all the interior surfaces of the substrate. Then the substrate is rotated and again lowered so that the other end is immersed in another predetermined charge of the slurry and the process is repeated. Thereupon, the substrate is again raised from the dip pan.

Abstract: A fluid circuit for a cleaning device having a mixture with separate water and cleaning fluid inlets and fittings interconnecting a pressurized source of water and a pressurized source of cleaning fluid responsive to change the mixing ratio of cleaning fluid to water as well as to assure the degree of mixing. The outlet of the mixing device is provided to a spray nozzle wherein the mixed fluid is projected onto a cleaning surface by an air stream through the spray nozzle. A common pump provides two levels of air pressure, a high one to the spray nozzle and a lower one to the pressurized sources of water and cleaning fluid.

Abstract: A method for impregnating the interior skeletal structure of a ceramic monolithic catalyst support with a slurry of catalyst material is disclosed wherein a predetermined amount of catalyst slurry is metered into contact with a first end of the support. A cover is placed over the periphery of a second, opposite end of the support in sealing relation thereto to define a vacuum chamber adjacent the second end. A vacuum is drawn on the cover to draw catalyst slurry into the skeletal structure from the second end whereby the interior skeletal structure is uniformly impregnated with the catalyst slurry.

Abstract: A door assembly for providing access between the interior of a pick-up truck passenger compartment or cab and the interior of a camper enclosure mounted on the load-carrying bed of the truck; the door assembly including a one-piece generally rectangular shaped door frame extending substantially the entire height of the cab interior and secured around the periphery thereof to the rearward side of the cab, a door hingedly mounted along a generally vertically extending axis so as to be movable between a closed position arranged generally coplanar with the rearward side of the cab and an open position extending outwardly into the camper compartment, a first sealing element extending between the door frame and the camper enclosure, and a second sealing element cooperable with the first element and sealingly engageable with the door when it is in its closed position.
