Patent CA-2081135-A1 (CA)
Inventor: KRULIK GERALD A
IPC: G03F7/30
Filed: 1992-10-22
Abstract: The use of aluminum sulfate to neutralize alkaline solu-tions yields a gelatinous precipitate.  When neutralization of the solution causes other materials to precipitate along with the gel, filtration of the precipitated materials is very difficult because of the gel.  The addition of water soluble magnesium, aluminum, and/or calcium salts as primary neutral-izing agents for an alkaline stripper solution of a photoresin, followed by the acidification of the resulting slurry to a pH of from about 2 to about 4 gives a slurry of the precipitated resin which may be filtered quickly.

Title: Particle mediated transformation of cotton
Inventor: MCCABE DENNIS E
IPC: C12N15/87
Filed: 1992-03-05
Abstract: A method for the particle-mediated transformation of cotton permits the direct genetic engineering of elite cotton lines without the need for tissue culture or callus proliferation. The technique involves excising the embryonic axes from germinating seeds and blasting particles carrying foreign genes into the embryonic axes. When the treated axes are released from an initial cytokinin treatment, the meristems recover and generate a shoot. By using a marker gene, the transformant population of the shoots can readily be identified. In this fashion, direct and expeditious transformations of elite cotton lines in Pima, Acala, Sea Island and Upland varieties can routinely be achieved.

Title: Non-systolic time delay and integration printing
Inventor: NELSON WILLIAM E
IPC: H05K3/00
Filed: 1993-01-20
Abstract: A method for printing or exposing photosensitive media is disclosed herein.     The method uses standard spatial light modulators with standard addressing circuitry. The data is written to the device for the first row, the photosensitive media is exposed to the light reflected from the device, and the device is turned off. The data from the first row is then written to the second line of the device, and new data is loaded into the first line of the device. The media is again exposed.  This is repeated until the entire region of the drum is completely exposed. The device can be repositioned to cover a different region of the drum and the process would be repeated.

Title: Treatment of waste or other material
Inventor: SATCHELL DONALD P JR
IPC: C01B17/58
Filed: 1993-02-26
Abstract: ABSTRACT TREATMENT OF SULPHURIC ACID     Waste sulphuric acid is dried in a drier 10 and the resulting dried acid is decomposed in a reactor 12 by contact with a volume of liquid sulphur through which oxygen is passed.  The decomposition products of the sulphuric acid initially comprise water vapour and sulphur trioxide.  The sulphur trioxide is reduced to sulphur dioxide by sulphur vapour.  The resulting mixture comprising sulphur, sulphur dioxide and water vapour has sulphur condensed therefrom.  The sulphur dioxide content of the gas mixture is reacted with hydrogen sulphide in a Claus plant 14 to form a sulphur product.  Alternatively the mixture containing sulphur vapour can be reacted with a hydrocarbon such as methane to form hydrogen sulphide and carbon disulphide which in turn are reacted with the sulphur dioxide to form the sulphur product.

Inventor: KIKKAWA YOSHITSUGI
IPC: C09K5/08
Filed: 1993-03-02
Abstract: Provided is an improved refrigeration system for pre-cooling natural gas or cooling a mixed refrigerant for natural gas liquefaction in a propane refrigeration process widely used for the liquefaction of natural gas.  The system comprises a plurality of plate-fin heat exchangers preferably arranged in a parallel relationship for passing a propane refrigerant as a vertical flow and pre-cooling natural gas or cooling a mixed refrigerant for liquefying natural gas, and a thermo siphon drum for the propane refrigerant consisting of a horizontally disposed, laterally elongated tank.  Because the passages of the heat exchanger for the natural gas or the mixed refrigerant extend over their entire length in mutually separate relationship, even when the propane refrigerant, the natural gas or the mixed refrigerant is in both gas and liquid phases, a high efficiency of heat transfer can be attained, and the size of the heat exchanger can be reduced.  In particular, from an economic view point, it is preferable if the thermo siphon drum serves also as a flash tank.

The gear mechanism driving a digit  attachment  member  in  a  rotational  movement therewith.  When  actuated,  the  reversible  motor causes the gear housing to rotate about the axis of the motor with the digit attachment member counter-rotating relative to the gear housing about another axis spaced apart from and parallel to the motor axis,  whereby  the  absolute  motion  of  the  digit attachment  member  and  therefore  of  the  patient's fingers  follow  a  compound  spiral.  The  compound spiral, depending on the ratios of the gears of the gear  mechanism,  can  follow  one  of  a  series  of multiple  lobed  compound  spirals,  having  open  or closed  loops.  The  range  of  motion  of  the  digit attachment  member  and  the  speed  thereof  can  be adjusted. Various motions can thus be imparted to the fingers of the patient.

Title: Capillary zone electrophoretic analysis of isoenzymes
Inventor: HSIEH YOU-ZUNG
IPC: C12Q1/00
Filed: 1992-11-16
Abstract: Disclosed herein is a methodology for analyzing isoenzymes using capillary zone electrophoresis ("CZE") techniques. Briefly, an isoenzyme-containing sample and a substrate capable of being catalyzed by said isoenzyme into a reaction product are introduced into a capillary column comprising a buffer. Most preferably, the buffer contains the substrate prior to introduction of the sample into such substrate-buffer. CZE separation techniques are applied to the column such that the isoenzymes are separated from each other into discrete zones. The separation techniques are terminated such that product is rapidly generated by the catalytic conversion of substrate by the isoenzymes, and accumulated, within each discrete zone, followed by detection of product. Information regarding the relative distribution of the isoenzymes can be derived from the relative distribution of the product.
