US Patent:

8136618, Mar 20, 2012

Filed:

Jan 21, 2009

Appl. No.:

12/356652

Inventors:

Michael George Field - Lansing NY, US

Assignee:

The Raymond Corporation - Greene NY

International Classification:

B60K 11/00

US Classification:

180 681, 180 683

Abstract:

A material handling vehicle includes a cyclonic motor cooling system for a motor compartment that accommodates an ergonomically designed operator compartment. Together, the motor compartment and cyclonic motor cooling system include a generally cylindrical housing with a tangentially arranged cooling air injection port at a lower end and exhaust port at a radially and axially opposite end. An air blower directs cooling air into the compartment where a cyclonic cooling air flow and a vortex cooling flow is produced. The cyclonic air flow cools more effectively than conventional linear air flow while also reducing dust contamination and buildup of the motors in the motor compartment.

International Classification:

B66F 9/065
B66F 9/075
F16F 7/10

US Classification:

254 2 R, 188378

Abstract:

A lift truck includes systems and methods for improved vibration control. Vibration control features reduce or eliminate motion of the truck in one or more of the X-axis, Y-axis, and Z-axis. Some embodiments may include, alone or in combination with the vibration control, stability control to further stabilize the motion of the truck.

Filed:

Nov 30, 1990

Appl. No.:

7/620116

Inventors:

Michael G. Field - Fabius NY
David N. Shaw - Manlius NY

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

F04B 4900
F01C 116

US Classification:

417310

Abstract:

The slide valve and the slide stop of a screw compressor are infinitely positionable over their range of movement. Movement is achieved by fluid pressure acting across an actuating piston in combination with the fluid pressure acting on the slide valve and slide stop plus a spring bias.

Appl. No.:

7/976763

Inventors:

Michael G. Field - Fabius NY
Erric L. Heitmann - Liverpool NY
Thomas S. Katra - Fayetteville NY

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

F01N 718

US Classification:

181241

Abstract:

Pulses are sensed at the inlet and outlet of a two-chamber reflective muffler and responsive thereto the cavities are tuned to the frequency of the pulses. Specifically, chamber walls are moved to have them located at spacings corresponding, respectively, to one half and one quarter of the wavelength of the pulses.

Appl. No.:

7/736550

Inventors:

Michael G. Field - Fabius NY

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

F02M 3500
F04B 2100
F01C 102

US Classification:

181229

Abstract:

A weight biased check valve is located in a reflective muffler at the entrance thereof. As a result, both the check valve and muffler are located proximate to a compressor which minimizes both the package size and the volume trapped upon shutdown. The axis of the weight biased check valve is skewed whereby the weight biasing effect is reduced.

Appl. No.:

8/775999

Inventors:

Peter T. Schutte - Syracuse NY
Stanley R. Grant - Baldwinsville NY
Michael G. Field - Groton MA

Assignee:

Carrier Corporation - Syracuse NY

International Classification:

F04B 4900

US Classification:

417309

Abstract:

Normally closed valve structure is located in a fluid path between the suction and discharge sides of a compressor. The valve structure opens upon a small pressure differential when the higher pressure is in the normal suction side which is indicative of reverse operation. Additionally, relief valve structure opens when the discharge pressure becomes excessive.
