Filed:

Dec 17, 1991

Appl. No.:

7/809834

Inventors:

James R. Brock - Arlington VA

International Classification:

B08B 900
B08B 1300

US Classification:

134 254

Abstract:

An apparatus and method for the transportation of golf balls, particularly at a driving range, which includes one or more tanks remote from a range house and in proximity to a driving target, in which golf balls can be separate from other objects and mixed with a fluid. This mixture is then pumped to a central location, during which the balls remain immersed in the fluid which is made to flow at high velocity, providing a cleaning action. The balls can then be subjected to further cleaning, if desired, separated from the fluid and the fluid returned to the tank in a substantially closed system. A high capacity ball cleaner is provided to furnish the further cleaning which is particularly adapted to be used with the ball processing system and method.

Appl. No.:

7/176185

Inventors:

James R. Brock - Arlington VA

International Classification:

H01H 4714

US Classification:

307 38

Abstract:

A circuit for the remote control of solenoid operated valves in an irrigation system reduces by one half the amount of wire required for the system. At least one pair of first and second solenoids are connected to a source of supply of alternating curent, typically through a low voltage circuit. A switching circuit selectively connects the source to the solenoids through a conductor having a diode network at either end of the conductor. One of the diode networks comprises a pair of diodes connected in anti-parallel relation across the switching circuit, and the other of said diode networks comprises a pair of oppositely poled diodes respectively connected between the conductor and a corresponding one of the solenoids. In operation, no current is supplied to the solenoids, current is supplied to the first solenoid on positive half cycles, current is supplied to the second solenoid on negative half cycles, or current is supplied simultaneously to both of said solenoids, depending on the operation of the switching circuit.

Abstract:

A wettable spray box for dispensing wettable agricultural spray powders in a tank of spray equipment so as to protect the operator from exposure to the powders is disclosed. The spray box comprises a box (10) with a lid (12) for attachment to the spray tank. The bottom of the box is fitted with a main pipe (18) which extends into the spray tank. A fill pipe (24) extends part way down the interior of the main pipe (18) and is connected to a source of water. One or more knives (34) within the box (10) are positioned to slit a bag of wettable powder which is inserted into the box. A water injector (40) extends into the slit bag, and a spray head (48) is positioned near the top of the box. An inserted bag is prevented from falling to the bottom of the box (10) by a rack or screen (28). In use, an unopened bag of wettable spray material is inserted into the box (10) and the lid (12) is closed to seal the box.
