Title: Method of preparing cyclic oligomeric polycarbonates
IPC: C08G64/22
Filed: 1988-02-24
Abstract: A catalyzed interfacial polycondensation 
aromatic polycarbonate process comprising mixing a water 
soluble metal salt of a dihydric phenol with an aqueous 
solution of a strong base and a polymerization catalyst in 
an inert organic solvent; heating the mixture; 
concurrently adding a carbonyl halide, additional strong 
base and additional water soluble metal salt of a dihydric 
phenol to the heated mixture to form the cyclic oligomeric 
polycarbonate; and recovering the cyclic oligomeric 
polycarbonate. The preferred process utilizes the 
di-sodium salt of bisphenol-A, triethylamine 
polymerization catalyst and methylene chloride solvent 
with phosgene to form the cyclic oligomeric 
polycarbonates. The cyclic oligomeric polycarbonate 
products are accummulated in the organic phase of the 
reaction mixture and recovered therefrom by conventional 
techniques.

Title: Process for the fabrication of a support for light sensitive material with an anti-coiling layer
IPC: G03C1/81
Filed: 1988-04-26
Abstract: For a waterproof support for light-sensitive materials with two successive coatings of an anti-curling layer applied to the back, gelatine is dried from the sol form in the first coating and hardened in such a way that, after drying of the first coating, the second coating which contains further hardener can immediately be applied without difficulty. Both coatings contain chromium(III) salts as hardener.

Title: Method and apparatus for storing, accessing, and processing voxel-based data
IPC: G06T15/00
Filed: 1989-11-09
Abstract: The present invention concerns a method of and apparatus for storing to and accessing from a memory device, one or more voxels of a beam disposed along one or more of a plurality of storage/retrieval directions of a 3-D matrix array and 3-D discrete voxel space. Voxels are stored into memory space by mapping the voxels along one of the plurality of storage/retrieval directions, into a plurality of independently successful memory modules in memory storage space. Each memory module is indexed by a memory module index and has internal memory cell addresses. The mapping is carried out in accordance with a linear skewing function which expressed in terms of x, y, and z coordinate directions and integer n. The voxels can be retrieved along one or more of a plurality of storage/retrieval directions by de-mapping one or more of the voxels from the memory storage space into 3-D voxel space using spacial parameters and integer n. The demapping operations of the present method are also used in order to determine the voxel depth measures of voxels along one of the storage/retrieval directions.

Title: Improved rf power-control circuit
IPC: H03G3/30
Filed: 1989-06-12
Abstract: An improved circuit for controlling the output power 
level of a radio frequency (RF) amplifier is disclosed. The 
circuit samples the output of an RF amplifier (10). The sample 
is amplitude modulated at a preselected modulation frequency 
and is passed to a detector (18). In response to the amplitude 
modulated signal, the detector produces a signal whose 
amplitude is indicative of the RF amplifier's output power 
and whose frequency is the modulation frequency. The 
amplitude of the signal produced by the detector (18) is then 
compared to a reference amplitude and the difference (error 
signal) is used to control the gain of the RF amplifier (10).

Title: Taut band piezoelectric actuator for wire matrix printing elements
IPC: B41J2/295
Filed: 1990-04-12
Abstract: This invention relates to printing elements for use in 
a serial wire matrix printer having a plurality of 
driven wire printing elements (12, 18, 20). Each 
printing element has actuating means associated 
therewith to drive the elements against a ribbon from 
a retracted position to an actuated position and 
returned. Each actuating means includes an elongated 
drive element anchored at opposite ends thereof to 
piezoelectric crystal stacks (28). The piezoelectric 
stacks have electrical supply means for causing 
expansion of the crystal stacks responsive to an 
electric signal. The drive element is normally 
maintained in a taut bowed position and is secured to 
the piezoelectric crystal stacks so as to be driven 
toward a straightened condition upon actuation to the 
piezoelectrical crystal stacks to thereby drive the 
printing element axially to the printing or actuated 
position from the retracted position upon actuation of 
the crystal assembly. Spring biasing means (22) are 
provided which coact with the printing element to 
return the printing element to its retracted position 
when the electrical signal is removed or reversed in 
polarity.

Title: Process for determination of a complete or a partial contents of very short sequences in the samples of nucleic acids connected to the discrete particles of microscopic size by hybridization with oligonucleotide probes
IPC: G01N33/53
Filed: 1990-04-12
Abstract: Determination of the formula of genomic DNA, i.e. genome 
sequencing, by a hybridization with oligonucleotide probes 
(YU Patent Application 570/87) envisages the use of 100000 
oligonucleotide probes and the same number of hybridizati­
ons with 6000000 of addressed sample-clones on filters in 
order to determine contents of oligonucleotide sequences in 
each clone. The process presents improvements in preparati­
on of samples for hybridization and improvements which 
enable one to follow gene expression by determining partial 
or complete fragment sequences of genomic DNA, mRNA or 
cDNA. By binding fragments of genomic DNA to discrete 
particles (DP) of a microscopic size which are recognizable 
in a step of reading experimental image, the necessity for 
addressed samples on filters is dispensed with and this 
drastically reduces automatical-robotical component of the 
process and allows miniaturization of the entire method 
from a level of industrial installation to the level of 
laboratory instrument. Processes for binding DNA fragments 
to DPs recognizable in common reactions, allow elimination 
of cloning, i.e. DNA amplification in the host cells and, 
in a process of library forming, need for formation of 
6000000 addressed samples in any one of the phases of a 
process for sequencing by hybridization.
