Appl. No.:

10/713972

Inventors:

William Wong - Elmhurst NY 11373

International Classification:

A01K 2900

US Classification:

294 14

Abstract:

A device for picking up animal excrement or other refuse that includes a disposable replaceable collection box placed in a saddle box. The saddle box is attached to an elongated handle which includes an outer tubular member surrounding an inner shaft. The saddle cooperates with chambers molded outward on the exterior of the disposable box to control opening and closing of the disposable box. A button like switch protrudes through the outer tubular member of the handle and is attached to the inner shaft member. Downward force applied to the switch transmits the force through the inner shaft, and causes downward motion of a pusher plate attached to the end of the inner shaft. The pusher plate applies the force to the disposable box through a ridge on the top of the box, thereby causing outward deflection of the side walls of the saddle box and inducing the box to open to receive dung. A pair of segregating flaps are attached to the interior of the box so that when the device is inverted, the flaps segregate the dung in the top portion of the box and prevent its falling out. In this manner another pile of refuse can be collected.

International Classification:

H01S 3/067
G02B 6/024

US Classification:

372 6, 385 11, 3593413

Abstract:

Various embodiments include large cores fibers that can propagate few modes or a single mode while introducing loss to higher order modes. Some of these fibers are holey fibers that comprising cladding features such as air-holes. Additional embodiments described herein include holey rods. The rods and fibers may be used in many optical systems including optical amplification systems, lasers, short pulse generators, Q-switched lasers, etc. and may be used for example for micromachining.

Inventors:

William H. Wong - Morristown NJ

Assignee:

Bell Telephone Laboratories, Incorporated - Murray Hill NJ

International Classification:

H05K 712

US Classification:

361380

Abstract:

A circuit support enclosure has drop-in receptacles in a base chassis structure for individual circuit components. After circuit components are placed in the drop-in receptacles, a retaining chassis structure is mated with the base chassis structure. The base chassis structure includes two tongs which have pawls which interlock with slots in the retaining chassis structure. The retaining chassis structure includes bifurcated retainers and clamp nodules that clamp the electrical components into their respective drop-in receptacles in the base chassis structure.
