Abstract: A motor vehicle ball joint assembly includes a ball stud having a ball stud axis with a shank portion and a ball end centered thereon.  A bearing liner has an open end disposed over the ball end with the open directed toward the shank portion. The bearing liner has a bearing surface engaging the ball end. A plurality of slits extend from the open end of the liner, defining a plurality of flex members.  The flex members operably deflect  to  receive  the  ball  end.   When  the  ball  end  is completely inserted in the liner, the flex members return to a locked position, axially retaining the ball end in the liner.  A stem engaging element has a stem axis and extends radially from the bearing liner.  The stem engaging element has metal engaging threads.  A rigid plastic case envelopes the bearing liner.  The rigid plastic case and bearing liner and the rigid plastic case cooperatively positively lock the ball end within the bearing liner.  The rigid plastic case fixes the flex fingers in the locked position,  thereby preventing axial displacement  of the ball stud from the liner.

Inventor: GRAHAM ROBERT J
IPC: A01C1/08
Filed: 1997-01-27
Abstract: A seed treater for providing a uniform coating of liquid chemical or the like to seed prior to planting. Overflow of seed accumulated in an internal chamber causes seed to splash out of the chamber and fall through an annular space between the chamber and the housing as a dispersed annular curtain. A circular, hollow conical spray pattern from a centrally positioned nozzle intersects the annular curtain. The annular curtain passes through the spray pattern at an angle resulting in uniform coating of the seed. The seed falls through a conical discharge for recovery. Preferably a cone at the bottom of the chamber creates an annular gap through which seed can drain at the end of the operation.

Abstract: A unique method and apparatus determines (310) which channels in a wireless communication system are both authorized for cordless operation and available. A channel is then selectively chosen (328) from this list to reduce the probability that an interferer will be on the chosen channel. For example, the channel could be randomly selected from all available channels or randomly selected from a limited group of available channels to avoid co-channel interference. Alternatively, the channel could be chosen based upon the level of the signal that last caused that channel to be blocked. Finally, the channel could be chosen based upon the number of channels from an available channel to the nearest blocked channel.
