Appl. No.:

09/643376

Inventors:

Troy Daniel Olson - Andover MN 55304

International Classification:

E04G 300

US Classification:

24828011, 396421

Abstract:

A new and improved apparatus for supporting a dial test indicator in a tooling machine comprising at least a pair of pivoting arms that are pivotally attached to a pair of pivoting ends which permit the arms to be positioned parallel to one another and operate in unison motion. This configuration allows the dial test indicator support to maintain constant latitude throughout a full of range of motion during adjustment thereof, resulting in an indicator support that can quickly assist in the acquisition of precise, accurate measurement of the workpiece. Further, the dial test indicator support requires no active adjustment of fastening screws and the alike during repositioning of the arms for progressive measurement of the workpiece. The dial test indicator support further comprises a mounting shank for attachment to a tooling machine spindle and a dovetail that is geometrically configured and capable of supporting a dial test indicator having either a mounting shank attached thereto or a dovetail-tongued mount. Additionally, the dial test indicator support can be adapted for use with conventional height gauges and can be utilized with a variety of tooling machines, such as milling machines, lathes, drill presses, and horizontal boring mills.

Abstract:

An irrigation system having a microprocessor-based controller for providing a desired degree of watering to an area which is divided up into zones, with each zone including a solenoid water valve in series with one or more water dispensing devices, such as spray heads or a drip irrigation tube. Also associated with each of the zones is a moisture sensor which is arranged to be periodically interrogated by the microprocessor-based controller and, when interrogated, provides an electrical signal proportional to the degree of moisture in the soil proximate the sensor. A feature of the invention is that the microprocessor-based controller is extremely easy to program due to the combination of a display screen on which various menus can be presented and a minimum quantity of push-button keys for calling up the menus and for altering sprinkling parameters that are displayed on the menu screens.
