Filed:

May 1, 2001

Appl. No.:

09/846994

Inventors:

Richard E. Hunter - La Jolla CA
William D. Holton - Vista CA
Loren W. Scott - Carlsbad CA

Assignee:

Hunter Industries, Inc. - San Marcos CA

International Classification:

B05B 304

US Classification:

239240, 239252, 239205, 239206

Abstract:

A sprinkler includes a riser having a lower end for receiving a pressurized fluid and a nozzle that is mounted at an upper end of the riser for rotation about an axis. A turbine is mounted for rotation inside the riser. A drive mechanism connects the turbine to the nozzle so that rotation of the turbine by the pressurized fluid rotates the nozzle. The sprinkler includes mechanisms for preventing over-spinning of the turbine when the pressurized fluid is air or a mixture of air and water. Damage to the turbine drive shaft or its bearings due to over-spinning of the turbine is thereby avoided. In one version of the sprinkler, the over-spinning prevention mechanism applies a brake force to the turbine. In another version of the sprinkler, the over-spinning prevention mechanism re-directs air or a mixture of water and air around the turbine.

International Classification:

F21S 8/08

US Classification:

362418, 362153, 362431

Abstract:

An adjustable height landscape light fixture includes an outer cylindrical body portion having a upper threaded segment and an inner riser portion telescopically mounted in the outer cylindrical body portion. A collet surrounds the inner riser portion. A threaded cap is screwed over the upper threaded segment of the cylindrical body portion. The threaded cap is configured to squeeze the collet against the inner riser portion to fix and un-fix a predetermined longitudinal position of the inner riser portion relative to the outer cylindrical body portion and provide a substantially water impervious seal between the threaded cap and the inner riser portion. An incandescent or LED upper light portion is mounted to an upper end of the inner riser portion.

International Classification:

B05B 1510

US Classification:

239205

Abstract:

A sprinkler unit comprises a tubular housing having an inlet for connecting to a source of water, a tubular riser telescopically reciprocally mounted in the tubular housing and moveable from a retracted position within the housing to an extended position from the housing, the riser having an outlet having a nozzle for distributing a stream of water outward from the housing, a passage connecting the inlet to the outlet, a retraction spring normally biasing the riser to the retracted position, and a shock absorbing coating on the retracting spring for absorbing the shock of movement of the riser to the extended position.

International Classification:

B05B 304

US Classification:

239204

Abstract:

A sprinkler unit comprises a housing having an inlet for connecting to a source of water, a rotating head mounted in an upper end of the housing and including an outlet nozzle for distributing a stream of water outward from the housing, a drive assembly including a turbine and a reduction gear drive train connecting the turbine to the head for rotating the head, the drive train having a gap for intermittently interrupting the drive for causing the head to intermittently pause during rotation thereof.

International Classification:

A61F 703
A61F 712

US Classification:

128401

Abstract:

A device for self-administered treatment of hemorrhoids and other rectal disorders generally comprises an outer vessel including a hollow, thin-walled, flexible elongated tubular body portion having an inner closed end and an outer closed end and dimensioned for manual rectal insertion of the inner end, and having an enlarged stop portion at the outer end to prevent rectal insertion of the outer end and to insure proper positioning during use. The inner end has a portion of larger circumference to prevent expulsion of the device during use by anal spincter action. Chemical components within the outer vessel produce an exothermic reaction. An inner vessel, disposed within the outer vessel, contains at least one of the chemical components, and being facturable upon flexion of the outer vessel, provides for mixture of the chemicals. The device is intended for insertion into the anal canal to raise the temperature of the wall surface to approximately 45. degree. C. In a preferred embodiment dissolution of a salt (calcium chloride) quickly raises the temperature of the device to the desired temperature and hydration of an oxide (calcium oxide) maintains this temperature.

International Classification:

US Classification:

137244

Abstract:

A diaphragm-type control valve for irrigation systems has an outer clam-shell housing that encloses a vertically reciprocable diaphragm assembly. A primary valve seat inside the housing is engaged and disengaged by a seal on the underside of the diaphragm to open and close the valve by connecting and disconnecting its inlet and outlet passages. Pressurized water from a lower inlet chamber of the valve travels through a small metering orifice in the center of the diaphragm assembly to an upper pressure control chamber above a flexible membrane of the diaphragm assembly. A solenoid actuated pilot valve is operatively coupled to the upper pressure control chamber for venting pressurized water therefrom to permit the diaphragm assembly to move upwardly to open the valve. A filter screen is mounted to the underside of the diaphragm assembly to prevent debris from clogging the metering orifice, clogging the small passages of the pilot valve, or fouling the solenoid. A cylindrical wiper element supported by a cylindrical carrier surrounds the filter screen and is moved up and down along the filter screen as the valve opens and closes to scour algae, mineral deposits and other debris from the surface of the filter screen which are carried away through the main outlet passage of the valve.

Abstract:

A method and apparatus for operating a center pivot irrigation system including a plurality of span units, each having a drive carriage having a hydraulically driven motor means for operating associated carriage wheels in response to hydraulic fluid supplied thereto under pressure through hydraulic fluid lines from a source thereof, is operated by supplying hydraulic fluid at a selectable value of constant volume fluid flow to the system to drive the system at a selectable average speed about its center pivot, the flow rate of fluid to individual motor means of individual span units which are ahead or behind of a predetermined relative alignment with the other span units being varied in response to changes in angularity sensed between adjacent span units in both forward and backward directions relative to the direction of travel of the system about its center pivot while the constant volume fluid flow through the system is being maintained at a selectable constant flow rate. An improved hydraulic adjustable rate flow valve accommodates fluid flow in reversible directions while maintaining close control or metering capabilities over the fluid flow through the valve in either flow direction.
