Filed:

Jan 14, 2009

Appl. No.:

12/353606

Inventors:

David C. Stieler - Lake Orion MI, US
Michael J. Zdroik - Metamora MI, US
Robert J. Doherty - Syracuse IN, US
Jackson Zel Roe - Goshen IN, US
Gary L. Handshoe - Wawaka IN, US

International Classification:

F16L 55/00

US Classification:

28514819, 123456

Abstract:

An apparatus for coupling components in a fuel delivery system together is presented. The apparatus comprises a first member having a first end, a second end, and throughgoing passageway therebetween. The apparatus further comprises a second member having a throughgoing bore therein. The throughgoing bore is configured to receive the first end of the first member. The first and second members of the apparatus are configured to be affixed together to create a joint between the first end of the first member and the inner wall of the bore of the second member such that the passageway and the bore are in substantial alignment with each other.

Appl. No.:

7/969861

Inventors:

Robert Doherty - New Hudson MI

Assignee:

Johnson Service Company - Milwaukee WI

International Classification:

H01H 3540

US Classification:

200 83SA

Abstract:

A pressure control for use in applications such as refrigeration, air conditioning and ice generating machinery includes a highly accurate snap acting switch, field adjustable trip points and reset points and a reference scale. The trip point is adjusted by means of an adjustment screw, while the reset point is adjusted by changing the differential, or the difference between the trip point and reset point. The differential is adjusted by adjusting the amount of "lost motion" within the control by employing an actuator which includes a cam surface and means for changing the position of the cam surface.

Robert P. Doherty - Hacienda Heights CA

International Classification:

F24F 1306

US Classification:

98 38E

Abstract:

A unit for heating or cooling multiple rooms including a plenum diffuser mounted parallel within a ceiling runner and supported by hangars within the ceiling plenum. Each unit includes a round inlet collar, an elongated plenum to form a "Venturi," hinged volume dampers, secondary air openings, a bottom plenum chamber, and a pattern controller. The volume dampers housed within the Venturi work in unison. When the volume dampers are open, the unit functions similar to any conventional heating or cooling plenum diffuser. Primary air (heating air or cooling air) will enter the unit and leave through a discharge opening with no change in the air quantity or temperature. As space cooling or heating requirements are met, the volume dampers close at a preset distance, the primary air is reduced (variable volume), the velocity is increased and induces (induction) warm return air through the secondary air openings from the ceiling plenum, or ducted room return, into the primary air stream. This maintains effective room air motion and varies the air discharge temperature (variable discharge temperature) to bring the space to the desired temperature quicker. A pattern controller is located at the discharge opening of the unit, which when rotated, will adjust the air system to numerous air patterns.

International Classification:

H01R 4300

US Classification:

29825

Abstract:

An improved method of manufacturing an electrical probe test head is provided for testing electrical circuits, such as, e. g. , IC-chips and circuit boards. The test head can be employed in circuit testers, such as, e. g. , circuit board testers and probe cards, to provide an electrical connection between the terminals of the circuit to be tested and external test circuitry. The method of manufacturing the test head includes selecting an electrical circuit having terminals arranged in a terminal pattern. Vertical probe pitch series sets are provided, each of which includes a plurality of electrically conductive rigid pins, which is made of a suitable material, such as, e. g. , tungsten. Each of the rigid pins has a pin shaft and a pin contact tip. The pin contact tips are configured in a pin pattern corresponding to the terminal pattern, i. e.
