Filed:

Dec 14, 1984

Appl. No.:

6/681936

Inventors:

David R. Lerner - Mount Vernon NY

International Classification:

H02B 110

US Classification:

361377

Abstract:

An ultrahighlight fluorescent light mounting system for filming, particularly in color. A head carries the fluorescent tubes and a removable light shield while the ballast is positioned in a container remote from the head. The head is set upon and swivable about an upper post, which is rotatably connected to a lower post, which in turn is set upon and swivable about a swivel piece extending from a standard stand. The head, light shield, first post, second post, stand, and ballast can all be dissembled from one another and placed in carrying cases.

Filed:

Jul 15, 1981

Appl. No.:

6/283403

Inventors:

David A. Lerner - Flushing NY

Assignee:

The Singer Company - Stamford CT

International Classification:

D05B 4500
D05B 5900

US Classification:

112278

Abstract:

A bobbin thread level detection and display arrangement for a sewing machine includes an array of light emitting diodes which are activated to convey to the sewing machine operator an indication of the quantity of thread left of the bobbin. To control the light emitting diodes, an arrangement utilizing a light source and a phototransistor is arranged proximate the bobbin. The circuitry for controlling the activation of the light emitting diodes also provides for a "fading in" of the individual light emitting diodes to provide a display in the nature of a bar graph.

Assignee:

Fritzsche Dodge & Olcott Inc. - New York NY

International Classification:

C07C 6976

US Classification:

560 70

Abstract:

Dialkyl-substituted. beta. -resorcylic acid esters having the structure: ##STR1## wherein each of R. sub. 1, R. sub. 2, and R. sub. 3 is lower alkyl may be readily prepared by reacting the corresponding dihydroresorcylic acid esters with sulfuryl chloride. These compounds, particularly, methyl 3,6-dimethyl-resorcylate and methyl 3-ethyl-6-methyl-resorcylate, have oakmoss-like odors rendering them valuable as perfume ingredients.

Filed:

Appl. No.:

6/182773

Inventors:

Helen Hooke - Port Chester NY
David Lerner - New York NY

International Classification:

G10H 303

US Classification:

84 128

Abstract:

A series of beat signals (e. g. sixteen) corresponding to a desired rhythm or tempo are recorded on one track of a multi-track magnetic tape, which is then cut and spliced into a loop just long enough to contain the entire series of recorded beats. During a performance the loop is used in a recorder designed to cause the recorded beat signals repeatedly to be played back by a first head at a first terminal, which can be connected through an amplifier to an ear-piece and/or lamp so that the reproduced beat signals can be heard and/or seen only by the performer. A second, combination record-playback-erase head in the recorder is mounted adjacent a second track on the tape and is connected by, for example, a foot-operated switch to a circuit which enables the second head instantaneously to be switched from a record to a playback mode, and vice versa. The performer can then use the foot-operated switch momentarily to switch the second head into its recording mode to record on the second track, during one complete revolution of the tape, background music or rhythm compatible to the beat signals. The last-recorded material can then be amplified and instantly played back through a second terminal to a live audience repeatedly as the performer continues the performance.
