US Patent:

49724193, Nov 20, 1990

Filed:

Sep 28, 1989

Appl. No.:

7/413812

Inventors:

Robert J. Burke - Thousand Oaks CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

H01S 300

US Classification:

372 2

Abstract:

A device to provide high current, low emittance electron beams with a long life cathode. The device consists of an undulator 7 which provides a source of ultraviolet light 15 for an ultraviolet photocathode 8. The undulator 7 needs a supply of electrons to produce the ultraviolet light which it can get by diverting a portion of a beam from a linear accelerator 3 before E. sub. 3 or after E. sub. 4 the electron beam traverses a free electron laser 5. The device is self-maintaining once a source of electrons is developed but needs a start-up source of electrons. The start up source can be provided by a pulsed cathode electron gun 1 which has to be on for a short period of time until the ultraviolet photocathode 8 is operated. Alternatively, the start-up source can be achieved by irradiating the UV photocathode 8 by ultraviolet light from a conventional laser 9, which can be aimed through the undulator 7 and subsequently provide a seed UV laser beam at lower power to assist regeneration of the high power UV beam in the undulator. In another embodiment UV light 15 can be sent directly from the free electron laser 5 to ultraviolet photocathode 8.

Appl. No.:

8/105639

Inventors:

Morton L. Barr - East Brunswick NJ
Paul J. Vincenti - Jefferson NJ
Robert V. Burke - Ridgewood NJ

Assignee:

The Mennen Company - Morristown NJ

International Classification:

A61K 146

US Classification:

512 17

Abstract:

Disclosed is a fragrance composition having enhanced efficacy for masking malodor for extended periods of time, to be used in deodorant compositions. The fragrance composition includes materials providing fruity, aldehydic and green notes, in an olfactory effective amount, and also includes at least 10% (e. g. , 10%-28%) by weight, of the total weight of the fragrance composition, of acetyl hexamethyl tetralin. The fragrance composition can be incorporated in a body deodorant (for example, a deodorant for axillary regions, such as a deodorant stick) to mask body malodor arising in, e. g. , axillary regions.

Assignee:

The Mennen Company - Morristown NJ

International Classification:

A61K 746

US Classification:

512 17

Abstract:

Disclosed is a fragrance composition having enhanced efficacy for masking malodor, for extended periods of time, the fragrance composition containing fragrance materials that provide a top note and/or a middle note and/or a bottom note, and also containing more than 28%, and up to 95%, by weight, of the total weight of the composition, of acetyl hexamethyl tetralin. The fragrance composition can be incorporated in deodorant compositions to be applied to a person's skin, e. g. , in axillary regions, to combat body malodor, including malodor arising in axillary regions.

Appl. No.:

7/277158

Inventors:

Robert J. Burke - Thousand Oaks CA

International Classification:

H01S 300

US Classification:

372 2

Abstract:

An approach is shown for eliminating the expense of a plurality of linear accelerators as used in a multiple electron beams free electron laser system. A single linear accelerator is used to simultaneously accelerate a plurality of electron beams by using an electron beam deflection means such as a bending magnet to cause multiple beams to converge to a single stream of electrons for acceleration by the linear accelerator and then using a similar beam deflection means to re-define the accelerated beams in accordance with their repsective enery levels into a similar plurality of output beams.
