Abstract: A method is provided for producing a membrane from polycarbonate-polyether-blockcopolymers with about 5 to 35 weight percent of repeating alkyleneethercarbonate units and about 95 to 65 weight percent of repeating bisphenol A-carbonate units, wherein the polyethyleneoxide blocks have a molecular weight from about 1,000 to 20,000, wherein the intrinsic viscosity of the copolymer is from about 180 to 300 ml/g as measured in chloroform at 25 DEG  C. and wherein the ultrafiltration rate is from about 4 to 200 ml/h.m2.mm Hg. In a first dissolving step a polycarbonate-polyether-copolymer is homogeneously mixed with a solvent at a temperature from about 80 DEG to 120 DEG  C. and in a second dissolving step the temperature is brought to about 140 DEG  to 180 DEG  C. to produce a true solution. The filtered solution is cooled to from about 20 DEG  to 50 DEG  C. and is then extruded through a nozzle into a bath comprising a nonsolvent for the polymer for precipitating the polymer. The precipitated polymer is then washed and dried. The resulting membranes improve the processes of hemodialyzing and of homofiltration.

IPC: C12Q1/68
Filed: 1987-07-01
Abstract: A DNA sequencing system and method are described to detect the presence of radiant energy emitted from different excited reporter dye-labeled species (DNA fragments) following separation in time and/or space, and the identity of the species which emit radiant energy closely spaced in wavelength. Functions of the emitted energy are obtained which vary over the wavelengths of the closely spaced spectra in different senses and the functions ratioed, whereby the ratio is indicative of the identity of the DNA fragments. The emitting portion of the reporter-labeled DNA fragment is preferably one of a family of fluorescent dyes based on 9-carboxyethyl-6-hydroxy-3-oxo-3H-xanthene. These xanthene dyes are covalently attached to the DNA fragments through the carboxylic acid functionality, preferably via an amide linkage. The dyes may be protected by including an alkoxy group at the 9-position. A spacer may be inserted between the dye and the amine. The fluorescent dye preferably is attached to the DNA chain terminators and provides many advantages. Thus only DNA sequencing fragments resulting from bona fide termination events will carry a reporter. The DNA sequencing may also be labeled using the xanthene dyes which have general utility as fluorescent labels. Also acyclonucleoside triphosphates are described as being useful as chain terminators in DNA sequencing using a modification of the Sanger method.

Title: Device for bending and hardening glass plates
Inventor: BOCELLI A
IPC: C03B23/033
Filed: 1984-07-19
Abstract: The rollers or curved rods and other elements supporting the glass sheets as well as the apparatus necessary for bending and/or tempering are preferably mounted on a pair of longitudinally flexible strips that rest on a pair of rigid templates having the desired curvature. Each flexible strip advantageously is a chain whose links are hinged on one another, these links being provided with flanges to which are fastened the rollers or curved rods, all other elements for supporting the glass sheets, and the elements necessary for bending and tempering. To permit modification of the curved profile, the templates are removable and interchangeable. To facilitate changing of the templates, the apparatus is equipped with a system for lifting the strips or chains. Such lifting system comprises one or more pivoting beams that are lifted by drive means such as a jack and a bent connecting rod. When the beams are raised, they lift the strip or chain off the template, thereby freeing the template to be replaced with a template having a different curvature.

IPC: C03C17/245
Filed: 1989-10-13
Abstract: A process for coating a moving ribbon of hot glass by chemical vapour deposition comprises establishing a first flow of a first reactant gas along the hot glass surface substantially parallel to the direction of movement of the glass, establishing a second flow of a second reactant gas as a turbulent flow at an angle to the glass surface, introducing said second flow into said first flow at said angle, while avoiding upstream flow of said second reactant gas in said first flow, directing the combined gas flow along the surface of the hot glass as a turbulent flow, and thereafter withdrawing the used coating gas away from the hot glass. The process enables a substantially uniform coating over 200 nm thick to be deposited in a short coating zone, and is useful for applying metal oxide coatings, for example fluorine doped tin oxide coatings, to hot glass.

Patent ZA-877655-B (ZA)
Title: Coin handling system
IPC: G07F9/00
Filed: 1987-10-12
Abstract: The coin handling system prevents coin to coin contact taking place in coin operated equipment. This is achieved by an arrangement whereby the presence of a coin activates a lever which then prevents a subsequent coin touching the previous one. A series of such levers are employed in the coin store of coin operated equipment, the actual number depending upon the number of coins to be stored. When the first coin is cleared from the store by a suitable gate arrangement, all coins move along the store by one position, the separation being maintained by the interaction of the levers and coins. The advantages of the system are that a wider range of coins from one coin set can be accommodated in a single store than is presently possible. The coin insertion sequence is maintained for the purposes of microprocessor control since a single store is used. Since coins cannot overtake each other the risk of coin jams is lessened.
