A high volume aeration device comprises a motor and propeller tube suspended in a pond by a float. A propeller on the motor shaft and inside the propeller tube creates a generally hollow water output stream that rises out of the propeller tube. A diffuser plate is longitudinally slidable inside the hollow water output stream. The water output stream strikes the diffuser plate and locates it at an equilibrium location whereat the force of the water output stream on the diffuser plate periphery equals the weight of the diffuser plate. If the propeller cavitates, the reduced water output stream causes the diffuser plate to fall toward the propeller and redirect the water output stream to the propeller. The redirected water output stream reloads the propeller and enables the aeration device to resume full output without outside intervention after the cause of the cavitation has been eliminated. The aeration device further comprises a weed guard that prevents motor shaft entanglement with weeds or the like, and a perforated cap that directs the water output stream into a high vertical column having a predetermined pattern.

The invention includes a method of aerating water.

Aeration apparatus and method

A bottle packaging apparatus including a dual line bottle conveyor, a cover conveyor for feeding contoured covers to the bottles on the conveyor, a magazine positioned above the cover conveyor and including a pair of guide tubes for supporting a stack of contoured covers, each cover including flexible means for separating one cover from another, and a tab or ring mounted on the bottom of the guide tube for bending the flexible means into engagement with the next cover to physically separate the cover from the stack when the cover is pulled off of the guide tubes.

Contoured package cover dispenser

A golf accessory for retrieving golf balls, repairing divots and placing ball markers, the accessory including a planar member having a ball holder section formed on one side and a flexible ball guide section on the opposite side for biasing the ball into the holder, the guide section including a pair of tapered tines for repairing divots and placing golf ball markers on the green.
