  • Patent number: 4999885
    Abstract: A clip for orderly arrangement and identification of flexible lines such as hospital intravenous tubing has a pocket for grasping the tubing and interengaging protrusions and engagement holes whereby the clip can be chained in a line with other similar clips. The clip has a pair of arms attached at one end to a base, free ends of the arms being attachable to the base of another clip. The base has engagement holes for receiving snap-in protrusions on the free ends of the arms, the arms being spaced and the protrusions preferably protruding outwardly for insertion into engagement holes on the inside of a cavity in the base after compressing the arms together with finger pressure. Tubing or wiring which is grasped by the clips is thus maintained in neat and orderly spaced relation. The clips can be coded by color, shape or the like and are preferably placed at spaced positions along the tubes for identifying a specific tube without tracing it back to its source of destination.

  • Patent number: 4957516
    Abstract: An inverse flow depth filter assembly includes an elongated, generally elliptical housing with gas inlet and egress means, and a bottom drain. A filter cartridge is suspended from the housing top so that an annular channel is created between the housing and the cartridge. The cartridge has passages at the top, leading to the egress means and an open bottom. Air enters the housing and is channeled downward through the annular channel until it reaches the cartridge bottom, quiets the turns upwardly through the filter. Heat exchange apparatus cools the down-flowing air and promotes condensation of the water. The heat exchange apparatus can include a plurality of fins fixed to the exterior of the housing to promote heat exchange with the surrounding atmosphere. Heat exchange fins disposed internally at the annular channel promote heat exchange between the flowing air and the housing. The fins increase the contact surface area for better heat exchange with the outside air.

  • Patent number: 4953790
    Abstract: A low cost sprayer and method of using the sprayer is disclosed. The sprayer is formed with a length of flexible tubing having an inlet end and a tubing outlet end. A nozzle is secured to the outlet end of the hose in a manner to provide a predetermined flow pattern upon rotation of the tubing and nozzle. In use, the inlet end of the tubing is placed within an agricultural chemical containing tank and a predetermined length of the remainder of the tubing is rotated by a worker as he walks through the area to be sprayed. By varying the radius of the rotating portion of the tubing and by varying the type of spray nozzle employed, the swath width and the droplet size of liquid chemical application can be closely controlled. Granular agricultural chemicals can be applied by rotating a granular material nozzle about its axis while rotating the tubing in a vertical plane.
