Title: Slide calculator for photographic lighting
Inventor: REED MURIEL A
IPC: G06C3/00
Filed: 1988-03-14
Granted: 1992-12-29
Abstract: SLIDE CALCULATOR FOR PHOTOGRAPHIC LIGHTING         ABSTRACT        The object of the invention is to provide a slide calculator to make the determination of flash-to-subject working distances (WD) easy and accurate for amateur and professional photographers. Light sources other than flash can be used. The calculator uses known factors such as lens f-stop, film speed, light-ratio, flash guide number (GN), flash power setting and filter exposure factors to determine WD's even when using multiple flashes simultaneously. The indicia on the slides and the indicia adjacent the appropriate windows on the panels are arranged in a predetermined manner and relationship to each other to permit a desired WD to be determined accurately. WD's for several flashes (each flash having a different purpose) can be determined and their affect on each other is compensated for in the calculations. Then the several flashes can be used in combination to achieve a desired lighting effect and correct exposure.

Title: Mold for electromagnetic continuous casting
Inventor: WEBER JEAN-CLAUDE
IPC: B22D11/01
Filed: 1988-03-21
Granted: 1993-04-06
Abstract: ABSTRACT            An electromagnetic mold  for vertical continuous casting of rolling slabs, featuring an inductor (6) and partly covering this an electromagnetic screen (a) is such that the vertical distance between the lower edge of the inductor and the lower edge of the screen is greater at the narrow sides of the mold (1) than at the broad sides of the mold (1).          As a result of this measure it is possible to prevent metal running out of the ingot head at the narrow sides during the start-up phase; this is achieved at the expense of an insig-nificant amount of melt circulation occurring in the molten head of the ingot.

Abstract: Described are new glycoprotein hormones capable of competing with natural hormones for the normal receptor binding sites but substantially incapable of effecting post receptor activities.      The glycoprotein hormones of the present invention have had specific (rather than all) oligosaccharide chains removed so as to effectively diminish biologic activity while not significantly reducing plasma half-life, thus improving the molecules effectiveness as an antagonist compared with conventionally produced molecules. The preferred glycoprotein hormones are ideally obtained by site-directed mutagenesis to selectively deglycosylate the protein. Also described are therapeutic treatments comprising the administration of the recombinant glycoprotein hormones of the present invention as hormone antagonists.

Abstract: ABSTRACT           REASSIGNMENT OF DIGITAL OSCILLATORS                  ACCORDING TO AMPLITUDE     A process for operating a digital synthesizer type of electronic musical instrument to rapidly make available digital oscillators to produce newly keyed notes even when all digital oscillators are currently active with previous assignments.  The process contains a way of maintaining a record of the digital oscillator with lowest amplitude, and reassigning this lowest amplitude digital oscillator to produce the new note on the rationale that the output of the lowest digital oscillator will be the least missed if an output has to be prematurely curtailed.  Besides a straight amplitude critereon, the process also allows for prioritizing some low amplitude outputs over others to make a more pleasing performance.  The invention also includes an apparatus for performing the process.

Title: High speed ecl input buffer for vertical fuse arrays

Granted: 1993-05-25
Abstract: A HIGH SPEED ECL INPUT BUFFER FOR       VERTICAL, FUSE ARRAYS                 ABSTRACT OF THE DISCLOSURE        An ECL input buffer is particularly well-suited for use with logic arrays where a large amount of current must be sunk by the row line, for example, when vertical fuse devices are used in an AND array.  The input buffer provides means for pulling down the row line such that the entire amount of current sunk by the input buffer from the row line need not pass through a current source, thereby minimizing current consumption of the input buffer. A pull down current source is used which causes a pull down transistor to turn on, thereby pulling down the row line while requiring only the base current of the pull down transistor to be consumed by the current source.  A pull up device is utilized and means are included for insuring that the pull up and pull down devices are not both turned on simultane-ously, thereby preventing a current spike through the pull up and pull down means.
