US Patent:

58864784, Mar 23, 1999

Filed:

Nov 13, 1997

Appl. No.:

8/969248

Inventors:

Raymond A. Smith - Severna Park MD
Roy G. Anderson - Baltimore MD
Edward H. Hooper - Catonsville MD

Assignee:

Northrop Grumman Corporation - Los Angeles CA

International Classification:

H05B 4116

US Classification:

315248

Abstract:

A coil extension of the RF coupling coil, surrounding an electrodeless light bulb containing an inert gas and selected chemical elements, generates a voltage at the distal end thereof which is higher than that which appears across the RF coupling coil proper, and wherein the high voltage from the distal end of the coil extension is returned to the light bulb through a point contact electrode located in relatively close proximity to the low voltage end of the RF coupling coil.

Appl. No.:

6/636774

Inventors:

Assignee:

Westinghouse Electric Corp. - Pittsburgh PA

International Classification:

H03H 700

US Classification:

333112

Abstract:

A high frequency directional coupler having improved intermodulation distortion performance is disclosed. The coupler includes input, output, reflected, and incident ports, and current and voltage transformers. The current transformer includes at least one primary winding connected between the inlet and outlet ports and at least one secondary winding coupled with the primary winding and connected between the reflected port and ground. The voltage transformer includes a plurality of series-connected primary windings connected between the reflected and incident ports, and a plurality of series-connected secondary windings coupled with said voltage transformer primary windings, respectively, and connected between the input port and ground. Shunt capacitors connected with the input, output, reflected and incident ports increase the bandwidth of the coupler.

Roy H. Anderson - Bellevue WA

International Classification:

B27B 3314

US Classification:

83833

Abstract:

An anti-kickback saw chain having a drop-away articulated depth gauge link preceeding each cutting or fibre removing link in a link sequence utilizing V-shaped cutter tooth links, each followed by a generally L-shaped raker tooth link. The depth gauge surface of the depth gauge link is spaced forwardly of the cutting tooth and the trailing edge thereof is located aft of the pivotal connection with the cutting tooth link when the pivot points of the links are aligned. The depth gauge link is designed to maintain cutting efficiency on the bar nose and to "drop away" from the kerf when an obstruction is encountered and to initiate a depth gauge restoring action with the associated cutting tooth so as to avoid jamming or locking of the chain and attendant kickback.
