Filed:

Aug 30, 2012

Appl. No.:

13/599627

Inventors:

Charles Jeffrey Spencer - Wilmette IL, US
John G. Serra - Pingree Grove IL, US
Martin Lee - Zionsville IN, US

Assignee:

Juno Manufacturing, LLC - Des Plaines IL

International Classification:

H05B 37/03

US Classification:

315112, 315130

Abstract:

A monitoring system is configured to manage lumen depreciation in a lighting fixture and includes an optic housing, a light source with a light-emitting diode (LED), a processor, and a memory device. The memory device stores instructions that cause the monitoring system to measure elapsed time during which the LED light source emits the light and, based on the elapsed time, determine a current level of the emitted light. In response to the current level changing from an acceptable level to an unacceptable level, an alert is provided to show that the emitted light has reached the unacceptable level. A reset input is received to remove the alert for a predetermined period of time. Changes in status of the LED light source are indicated.

International Classification:

F21V 7/07
F21V 29/00
F21S 8/06

US Classification:

362147, 362347, 362235

Abstract:

A downlight fixture includes an optic housing, a light-emitting diode (LED) array, and a lens-less reflector. The LED array emits directional light rays in a downward direction towards an illuminated target. The reflector is mounted within the optic housing and adjacent to the LED array. The reflector has a hyperbolic wall continuously extending between a narrow neck and a wide bell. The light rays are spread into a light beam within the reflector upon making contact solely with the hyperbolic wall.

Appl. No.:

8/673295

Inventors:

Charles Jeffrey Spencer - Chicago IL

Assignee:

Appleton Electric Company - Chicago IL

International Classification:

H01H 920

US Classification:

200 5012

Abstract:

A fuse shield plate is pivotally mounted over the fuses which are electrically associated with a disconnect switch. The switch operating lever is connected to an interlock rod which extends to a dead front receptacle. Interfitting elements on the fuse shield and the interlock rod prevent the fuse shield from being opened when the operating lever has been moved to close the switch contacts. When the fuse shield is opened to expose the fuses, the interfitting elements prevent the operating lever from being moved to close the switch contacts.

Appl. No.:

8/713987

Inventors:

Vaughn Terrey Hawthorne - Lisle IL
Charles P. Spencer - Staunton IL
Terry L. Pitchford - St. Louis MO

Assignee:

Amsted Industries Incorporated - Chicago IL

International Classification:

B61F 500

US Classification:

1051993

Abstract:

A freight railcar undercarriage constant-contact sidebearing arrangement provides a load force transfer mechanism with a more direct or less redundant force transfer path between the railcar body with its lading and the sideframe and wheels of a truck assembly, which system obviates the present use of a bolster center plate structure for load transfer, carries all the load forces through the side bearing assemblies, fulfills the dynamic operating requirements of the American Association of Railroads standards, reduces the weight of the railcar while maintaining the load-carrying capacity, and is particularly adaptable to three-piece truck assemblies in broad use on freight railcars.

Appl. No.:

7/607828

Inventors:

Franklin S. McKeown - St. Louis MO
Charles Moehling - Arlington Heights IL
Charles P. Spencer - Staunton IL

Assignee:

Amsted Industries Incorporated - Chicago IL

International Classification:

B61F 540

US Classification:

105207

Abstract:

Friction shoes are immobilized within the pockets of a railcar truck bolster by threaded pins that are inserted through apertures in the pocket walls and friction shoes and guided into the inboard pocket wall apertures by a concentric tapered surface within the pockets on the inboard pocket walls.

Filed:

Appl. No.:

8/560971

Inventors:

V. Terrey Hawthorne - Lisle IL
Charles P. Spencer - Staunton IL
Charles L. Van Auken - Dillsburg PA
Terry L. Pitchford - St. Louis MO

Assignee:

Amsted Industries Incorporated - Chicago IL

International Classification:

B61F 526

US Classification:

1052181

Abstract:

A sideframe pedestal jaw accommodates a bearing adapter which locks the adapter to the sideframe, thereby preventing it from all forms of movement within the pedestal jaw opening. Locking the bearing adapter forces the truck axles to remain at a right angle with respect to the sideframes. Maintaining this right angular relationship substantially curtails truck warpage, which induces wheel misalignment that leads to undesirable truck hunting and high speed instability.

Assignee:

AMSTED Industries Incorporated - Chicago IL

International Classification:

B61F 500

US Classification:

105207

Abstract:

A railway truck assembly has an arrangement for constraining the free travel clearance between the mated bolster and side frame at the side frame window, and more particularly for reducing or eliminating the clearance or separation gap between the bolster lands and the side frame column wall at the outer edges of the bolster lands and the column wall for reduction of truck warping during service.

Appl. No.:

8/700301

Inventors:

Vaughn Terrey Hawthorne - Lisle IL

Terry L. Pitchford - St. Louis MO

Assignee:

Amsted Industries Incorporated - Chicago IL

International Classification:

B61F 500

US Classification:

105219

Abstract:

An integrally cast bearing adapter arrangement is provided in the pedestal of a railcar truck side frame, which side frame is cast with a pedestal jaw having a roof, and vertical walls of a first and second leg which roof and walls operate as a bearing adapter to receive and grasp a bearing assembly outer surface at a horizontal diameter of the bearing assembly for an axle end without introducing the manufacturing and assembly tolerances from discrete component assemblies, thereby avoiding the lateral displacement associated with the added tolerances and operating to minimize angular displacement between each mated axle and side frame.
