    Abstract: A compound conduit containing inner and outer conduits with apertures in the former that are angled to direct jets of fluid in a rearward direction from the inner conduit into the annular space is used to draw sludge or undesirable material from a vessel without imposing a vacuum on the system. In conjunction with the compound conduit is a rotary tube seal that allows the conduit to be mounted to an orifice in a tank wall and pivoted or rotated over a range of angles. A tubing drive mechanism grasps the tubing at locations well removed from the distal end and causes the tubing to travel in the direction of the tubing axis. The gripping members in the mechanism engage the sides of the tubing and are capable of shifting position relative to each other to accommodate changes in the curvature of the tubing.

  • Patent number: 5964325
    Abstract: An improved bushing assembly for the inboard end of a brake cam shaft is provided with a bushing which establishes a grease flow pathway within the bushing assembly. Grease enters a cavity formed from a pair of housing halves which contain the bushing through a grease zerk which is directly connected to a first radial hole in the bushing, so the fresh grease injected goes directly to the grease reservoir between the bushing and the shaft. Flow channels provided in the bushing interior surface guide the grease around the shaft to a second radial hole which is diametrically opposite the first radial hole. A seal on the shaft restricts grease flow outwardly from the bushing along the shaft. Grease may be purged through the second radial hole to an annular space between the bushing and the interior surfaces of the housing halves, from which the grease may exit the housing around the periphery of a window in one of the housing halves through which the grease zerk passes.

  • Patent number: 5242228
    Abstract: A spherical slide bearing having dust covers fixed by outer sealing collar portions interposed between a housing and a bearing or bearings. The interposed outer sealing collar portions of the dust covers are retained by flange portions of the housing and the bearing such that they are not forced out through narrow gaps therebetween through which bellows of the dust covers pass. Interference by the outer sealing collar portions with the degree of angular movement of a ball stud of the spherical slide bearing and damage to the dust covers is thus prevented. Tapered motion limiting surfaces incorporated into one of a ball stud, an inside bearing surface, and a ball stud and an inside bearing member surface provide an increased range of angular movement while protecting the dust cover from damage.

The bearing guard is used in connection with self-aligning bearings which support the ends of a rotatable shaft provided on the machine and which is exposed to a work cavity in which the chipping, shredding or grinding operations take place. The bearing guard protects the bearings from material which is retained on the rotatable shaft during operation of the machine. The bearing guard comprises a shield surface disposed between the work cavity of the machine and the side of the bearing facing the work cavity. The shield surface has an opening through which the rotatable shaft of the machine passes. The opening is in relatively close dimensional tolerance with respect to the outer surface of the shaft, so as to resist contact of material retained on the shaft with the side of bearing during operation of the machine.

  • Patent number: 4649853
    Abstract: A siren comprises a compressed air supply which is deflected by stationary deflectors to exit radially through stator ports. A rotor with spaced ports rotates between the stator and deflector thereby opening and closing the stator ports. Stationary vanes are disposed at circumferentially spaced locations, and constitute together with the deflector plate and stator and rotor housing, plenums. There are fewer rotor ports than stator ports, which generates an out-of-phase acoustical pattern which creates an acoustic combination from the stator ports of an acoustic output at a distance from the siren which is more uniform spatially. The thermoplastic seal between the stator and the rotor has minimal clearance under operating conditions having been run-in and plastically deformed at a temperature higher than for normal operation.
