Patent BG-48869-A1 (BG)
Title: Method for preparing of grafted copolymers of polyacrylonitrile
Inventor: STOJANOVA VESELKA S
IPC: C08F265/08
Filed: 1989-07-31
Abstract: The copolymers of polyacrylonitrile (PAN) have potential uses in enzymologic engineering as carriers for immobilizing enzymes and cells. They are prepared using a method, which increases the extent and efficiency of grafting without using an inert gas. The method involves generating active sites by a photochemical or irradiation route. The photo-chemically activated PAN fibres are boiled for 1-2 hours in 0.45-0.60 % solution of benzophenone in acetone. After drying, the fibres are exposed to an UV light source with power rating between 44 and 125 W. When radio-chemically activated, the PAN fibres are wetted in glycidilmethacrylate (GM) or solutions of the same, followed by irradiation with γ rays at 2.5 Mrad. The photochemical grafting of GM and 2-hydroxyethylmethacrylate (2-XEMA) is achieved by dispersing PAN fibres in a mixture containing GM (GM and 2-XEMA), methylethylketone, water, iron sulphate and, in some cases, dimethylformamide. The duration of the graft copolymerisation is 3-4 hours at 70-75 degrees C. The ungraft homopolymer is separated by washing the modified PAN fibres with acetone, while the graft copolymer is vacuum-dried at 40 degrees C.

Title: Procede de commande de la concentration de solution dans une ligne de decapage de bande
Inventor: SIMPSON STEPHEN D
IPC: G01N31/16
Filed: 2002-03-25
Abstract: L'invention concerne un système de commande automatique destiné à la concentration d'acide dans une ligne de décapage de bande d'aluminium. Une bande d'aluminium est mise en contact avec une solution acide lorsqu'elle passe dans un bain de décapage acide, et la concentration d'acide dans le bain est réglée par addition d'acide concentré ou d'eau au bain. Une sonde de conductivité produit un signal caractérisant la concentration d'acide libre du bain, et un titrateur de processus en ligne produit périodiquement un deuxième signal caractérisant la concentration d'acide libre réelle et la concentration d'acide totale. Ces premier et deuxième signaux servent à obtenir une valeur corrigée de la concentration d'acide libre. La concentration d'acide du bain est ensuite réglée de manière adéquate sur la base de la valeur de conductivité spécifique corrigée.

Patent CA-2008674-A1 (CA)
IPC: B60J5/14
Filed: 1990-01-26
Abstract: This invention provides two forms of improved guards for a roll-up door. The first form (58 or 59) is intended to prevent shifting cargo from interfering with becoming interlocked with the lowered door. This form has a vertically-elongated guard which is adapted to overlie the vertically-spaced hinges, and has opposite marginal end portions closely spaced to the knuckle portions of such hinges. This first form reduces the stepped configuration of prior art hinges, and therefore reduces the opportunity for shifting cargo to become interlocked with the door. The second form (111) is mounted on the door and track, and is designed to prevent shifting cargo from entering the space through which the door must pass as it its raised or lowered.

Title: Test signal generator position cursors
Inventor: MELLING LAURENT A
IPC: G09G5/00
Filed: 1990-01-30
Abstract: Abstract of the Disclosure A test signal generator (12) applies a test pattern to a device under test (10).  The output of the device under test is displayed on a video picture monitor (16).  The test signal generator inserts a cursor (13) into the test pattern, the position of the cursor within the test pattern being variable.  From the cursor the test signal generator also generates a trigger signal.  The trigger signal may be used to trigger the horizontal sweep of a waveform display device (14) to which the output of the device under device is input.  By observing the picture monitor an operator may adjust the cursor to a position just prior to an anomaly in the displayed test pattern so that only that portion of the output waveform of the device under test in the vicinity of the cursor is displayed on the waveform display device.

IPC: A61K9/08
Filed: 1990-03-27
Abstract: Stable, clear, antimicrobially effective, ophthalmic formulations are disclosed which provide an antimicrobially effective preservative. The formulations include an ophthalmologically effective amount of a drug, which is a -COON group-containing non-steroidal anti-inflammatory drug (NSAID) in combination with an antibiotic drug, and a preservative system formed of a quaternary ammonium preservative and a nonionic polyoxyethylated octylphenol surfactant, all in an aqueous vehicle. The preservative system can be used with other formulations which require the preservative to be ophthamologically acceptable and antimicrobially effective. These formulations are useful for treating diseases and/or conditions that are either caused by, associated with or accompanied by inflammatory processes, including, among others, glaucoma, cystoid macular edema, uveitis, diabetic retinopathy and conjunctivitis, or any trauma caused by eye surgery or eye injury. The ophthalmologically acceptable antibiotic is preferably tobramycin which has been found not to interfere with the rate of diffusion of the NSAID. The combination of the NSAID and antibiotic is particularly effective in simultaneously preventing and/or eliminating infection while preventing and/or eliminating inflammation.
