  • Patent number: 6065482
    Abstract: A compact chain belt-type conveyor for conveying articles along a non-linear path through an industrial washer and drier. The chain belt-type conveyor provides an article sensing means wherein the sensing means is responsive to the presence of an article at a predetermined station along a predetermined non-linear path. A signalling means, responsive to the sensing means, signals a driving means to stop the conveyor when an article is present at the predetermined station for a predetermined amount of time and starts when an article is absent from the predetermined station. The signalling means ensures that each article will only be placed through one washing and drying cycle. An article holding means may be provided to secure the articles along the conveyor and provide proper orientation of the articles through the washing and drying process. A chain mesh construction conveyor may also be utilized to support and carry articles without the use of the article holding means.

The signalling means ensures that each article will only be placed through one washing and drying cycle since a washed article must be removed from the predetermined station of the conveyor before the driving means will continue to drive the conveyor. An article holding means may be provided to secure the articles along the conveyor and provide proper orientation of the articles through the washing and drying process.

  • Patent number: 4893642
    Abstract: Apparatus for cleaning/deburring manufactured parts, each part having an established axis of rotation, includes a conveyor operable to convey the parts in succession in intermittent step-by-step movement to a cleaning/deburring station and a drying station. At each of the cleaning/deburring and drying stations the part is driven in high speed rotation about its axis by a part rotating device. At the cleaning/deburring station the rotating part is sprayed with high pressure fluid and at the drying station high velocity air is discharged tangentially against the rotating part to strip residual fluid from the part. The spray nozzle assembly can be stationary, or can take the form of a transversing assembly for reciprocating movement along the longitudinal length of the part. Additionally, the transversing assembly can include rotation of the nozzle assembly about an axis as the nozzles are reciprocated longitudinally.

  • Patent number: 4732589
    Abstract: A water control valve in a wet air scrubbing device to discharge and direct water flow within the scrubber. The valve is composed of a conical valve body made of polyurethane and a fluid discharge receptor firmly attached to the air scrubbing device and connected to a water source. The conical valve body is movable into and out of engagement with the discharge repcetor. The conical valve body of the present invention is resistant to degradation by solvent vapor, resists contaminant adhesion and provides self-sealing engagement when the valve body is brought into contact with the discharge receptor.
