Title: Method of making double-stranded DNA sequences
Inventor: JAYARAMAN KRISHNA C O EASTMAN
IPC: C12Q1/686
Filed: 1989-09-13
Abstract: A method of synthesizing double-stranded DNA sequences is disclosed. The method comprises the steps of:
     (a) preparing a first series of oligodeoxyribo­nucleotide fragments which, when joined in proper sequence, form a DNA coding strand;   (b) preparing a second series of oligodeoxyribo- nucleotide fragments which, when joined in proper sequence, form a DNA strand complementary to the coding strand;   (c) compelling hydrogen bonding and ligation in proper sequence between the first and second series of oligodeoxyribonucleotide fragments prepared in steps (a) and (b) in a single reaction to produce the entire double-stranded DNA sequence;   (d) treating the double-stranded DNA sequence with one oligonucleotide primer for each strand under hybridizing conditions;   (e) polymerizing an extension product of each primer that is complementary to each strand of the double-stranded DNA sequence which is a template for forming the primer extension product;   (f) denaturing the product of step (e) to separate the primer extension products from their respective templates to form four separate single-­stranded DNA sequences;   (g) treating the denatured product of (f) with oligonucleotide primers, such that a primer extension product is synthesized using each of the single strands produced in step (f) as a template resulting in amplification of the double-stranded DNA sequence; and   (h) repeating steps (d), (e), (f) and (g) until the desired quantity of the double-stranded DNA sequence is formed.

Abstract: A fabric ribbon having multicolored regions has coloring matter in the regions of only flushed pigments in a liquid vehicle. Flushed pigments do not migrate between colored regions under normal conditions, and therefore mixing of the colors is avoided without alteration of the fabric or use of a fabric with special characteristics or regions. 
     Flushed pigments have very small particle size and perform like dyes with respect to replenishing the ribbon for good ribbon life. Yet, the ribbon colors do not bleed together, a characteristic of pigments.

Abstract: A GMSK modem is provided and comprises a baseband modulator section and demodulator section coupled to an FM transmitter and receiver, respectively. The Modulator section includes a digital waveform generator for generating a GMSK baseband signal from a binary digital data source. The output of the waveform generator approximates the baseband signal output of a premodulation filter with a Gaussian impulse response having a normalized noise bandwidth of between 0.25 and 0.45 in series with a gain controlled amplifier. The gain is adjusted such that the modulation index of an RF signal modulated with the baseband signal is between 0.5 and 0.7. 
     The demodulator section receives the analog output of a discriminator-based FM receiver with a phase equalized Butterworth IF filter. The demodulator section comprises a binary quantized loop bit timing recovery subsystem and one or the other of two data detectors. The two data detectors comprise a two-bit integrate-and-dump type filter and a two-bit multithreshold integrate-and-dump type filter. The binary quantized loop is also connected to a signal quality detector for altering the mode of operation of the loop according to the amount of noise in the baseband signal.

Abstract: An aspheric optical surface in the form of an aspheric mirror comprises a first element (12) defining a spherical reflector and a second element (18) which constitutes a support for the first element and is dimensioned to mate with the rear surface of the first element along an interface zone (36). Interface contour means (28), such as a plurality of shims, are disposed within the interface zone and produce a differential contour between the first and second elements. The interface contour means serve to modify the curvature of the spherical reflector and may, for example, modify the X-axis radius of curvature without significantly modifying the Y-axis radius of curvature. Compression means serve to compress the first and second elements together so that the interface contour means modify the curvature of the spherical reflector in order to produce the aspheric mirror.
