Filed:

Jul 1, 2003

Appl. No.:

10/611096

Inventors:

Charles R. Schenk - South Bend IN, US

Assignee:

Cummins, Inc. - Columbus IN

International Classification:

F01P001/06

US Classification:

123 4131, 165 804, 361687

Abstract:

The present invention is directed toward a lift pump mounting bracket for an electronic control module cooler. In a preferred embodiment of the present invention, the lift pump is mounted directly to the ECM cooler by means of a pair of brackets which engage frustoconical-shaped grommets on either end of the lift pump. The grommets provide vibration dampening for the lift pump, while mounting the lift pump directly to the ECM cooler provides a convenient place for such mounting and, typically, ease of access should the lift pump need to be serviced. The frustoconical shapes of the mounting grommet allow the lift pump to be removed upon the disassembly of only a single one of the pair of mounting brackets, thereby making disassembly quicker and more convenient.

Appl. No.:

10/755774

Inventors:

Charles R. Schenk - South Bend IN, US

Assignee:

CNH America LLC - New Holland PA

International Classification:

A01F 12/28

US Classification:

460109, 460 59

Abstract:

A device and method is disclosed for effecting movement and extending the clearance spacing between a rotor of a combine and a concave to allow for easy removal of lodged material. The apparatus and method additionally provide a reduction in rotor actuation motor torque and an increase in rotor mechanical advantage. Finally, the apparatus and method provide a travel limit to prevent a concave from being raised into, and having contact with, a rotor of a combine.

Inventors:

Charles R. Schenk - South Bend IN, US

Assignee:

CHN America LLC - New Holland PA

International Classification:

A01F 12/28

US Classification:

460109

Abstract:

A device and method is disclosed for allowing a combine operator, from the operator's station, to automatically transversely position a pinch-point of a concave relative to a rotor of a combine in accordance with the clearance spacing set between the concave and the rotor, thereby minimizing operator effort without sacrificing combine performance.

International Classification:

F25D 17/06
A47F 3/04
F25B 1/00
F28D 7/02

US Classification:

62 89, 62255, 62419, 62498, 165163

Abstract:

A refrigerated display case is provided that includes a display chamber for displaying product. The display chamber includes a product tray for supporting the product. A cooling chamber is arranged beneath the product and is in communication with a surface of the product tray. The cooling chamber is sealed from the display chamber, in one example, and includes a cooling coil. A fan is in communication with the cooling chamber and cooling coil. The fan circulates a cooling flow through the cooling coil. The cooling flow moves across the surface and absorbs heat from the product tray by convection. The cooled product tray removes heat from the product by conduction.

Appl. No.:

12/799424

Inventors:

Charles R. Schenk - Edwardsburg MI, US

Assignee:

South Bend Controls, Inc. - South Bend IN

International Classification:

F16K 31/02
H01F 7/16

US Classification:

25112915, 335255

Abstract:

In one embodiment of the invention, a solenoid is provided that is energizable by an electric current and includes: a pole piece, which is configured from a magnetizable pole material; an armature, which is movable when an electric current is passed through the solenoid; and an electromagnetic coil. A current passes through the coil when the solenoid is energized; the coil includes a central opening, wherein the pole piece is at least partially located. The diameter of the central opening may be less in a mid region than at upper and lower ends of the coil. At least one of either the upper or lower inside ends of the central opening of the coil may be beveled or contoured with a radius. The magnetic flux generated when the coil is energized has an enhanced flow path reducing the saturation in the transitional area at the upper and lower inside ends of the central opening as compared to a standard coil.
