Patent CA-1305931-C (CA)
Inventor: KNOWLES JONATHAN
IPC: C12N1/21
Filed: 1985-04-12
Granted: 1992-08-04
Abstract: YEAST STRAINS PRODUCING CELLULOLYTIC ENZYMES AND METHODS AND MEANS FOR CONSTRUCTING THEM            ABSTRACT OF THE DISCLOSURE            Described are methods and means for the construction of strains of yeast capable of producing cellulolytic enzymes.            This is achieved by the transfer of chromosomal genes or cDNA copies of mRNAs coding for cellulolytic enzymes isolated from the fungus Trichoderma reesei to yeast cells using recombinant DNA vectors capable of replicating in yeast. The correct expres-sion of these cellulolytic genes in yeast leads to the produc-tion of cellulolytic enzymes which are secreted from the cell. This allows the yeast to hydrolyze .beta.-1,4-glucan substrates such as cellulose.

Title: Two reactor high-recovery sulfur plant and process
Inventor: REED ROBERT L
IPC: C01B17/04
Filed: 1985-08-28
Granted: 1991-07-23
Abstract: ABSTRACT Sulfur is recovered from an acid gas stream com-prising hydrogen sulfide by successively reducing the hydrogen sulfide in a thermal reaction zone, a first posi-tion Claus catalytic conversion zone operated above the sulfur deposition point, and a second position Claus cata-lytic conversion zone operated under conditions effective for producing and depositing elemental sulfur on the cata-lyst.  Periodically, the reactor in the second position is switched to the first position, the reactor in the first position having previously been preconditioned thereby avoiding a temporary increase in emissions after switching.

Title: Vaned slinger for pumps
Inventor: LAGRANGE NYLE D
IPC: F04D29/10
Filed: 1986-09-18
Granted: 1991-03-05
Abstract: Abstract of the Disclosure A slinger for a submersible electric pump protects a motor shaft bearing as well as a shaft seal.  The slinger is provided with four, inclined, curved projections or vanes which are operable to propel sand or other potentially abrasive, grit-like contaminants away from an area adjacent the shaft seal.  A pair of outlet slots disposed horizontally adjacent a lowermost portion of the slinger cooper-ates with the vanes to enable passage of the con-taminants to an area external of the pump, such that the contaminants do not accumulate within the pump itself and the likelihood that the contaminants will enter the first pump stage is significantly reduced. Each of the vanes has a face inclined slightly relative to the frustoconical outer surface of the slinger, and each face terminates in a curved lead-ing edge and a curved trailing edge.  The vanes direct the contaminants toward the lowermost portion of the slinger where maximum outward thrust is developed.

Title: Hybridization process utilizing a combination of cytoplasmic male sterility, cytoplasmic herbicide tolerance, and herbicide tolerance attributable solely to nuclear genes
Inventor: BEVERSDORF WALLACE D
IPC: A01H1/02

Granted: 1992-06-23
Abstract: HYBRIDIZATION PROCESS UTILIZING A COMBINATION OF CYTOPLASMIC MALE STERILITY, CYTOPLASMIC HERBICIDE TOLERANCE, AND HERBICIDE TOLERANCE ATTRIBUTABLE SOLELY TO NUCLEAR GENES               Abstract of the Disclosure The present invention provides a convenient route for producing a predetermined hybrid variety of a crop which is capable of undergoing both self-pollination and cross-pollination.  Cytoplasmic male sterile plants which also exhibit cytoplasmic herbicide tolerance (i.e., to a Type A herbicide) and tolerance to a different herbicide attributable solely to nuclear genes (i.e., to a Type B herbicide) are the key plants for use in the present process.          The maintainer and restorer plants exhibit tolerance to different herbicides (i.e., to either a Type A herbicide or a Type B herbicide).  The economical bulk planting of the parent plants is made possible during each step of the process.  For instance, cytoplasmic male sterile plants, plants resulting from the self-pollination of a maintainer, and restorer plants can be grown in a substantially random population, with the self-pollinated main-tainer plants being destroyed by an appropriate herbicide prior to pollination, and the self-pollinated restorer plants being destroyed by an appropriate herbicide immediately following pollina-tion or in the subsequent generation.  The process of the present invention is applicable to grain crops, forage crops, seed propagated fruits, seed propagated ornamentals, and industrial species.  In a particu-larly preferred embodiment a predetermined variety of Brassica napus (i. e., rape or improved forms thereof known as canola) is formed which is the product of cross-pollination.

Title: Universal expansion joint
Inventor: LUKASIEWICZ STANISLAW
IPC: F16L51/02
Filed: 1986-11-18
Granted: 1992-01-28
Abstract: ABSTRACT OF THE DISCLOSURE         The conventional expansion joint for use in pipelines and other structures includes a bellows sandwiched between two end plates which are used to mount the joint in the pipeline, and rings of T-shaped cross-sectional configuration.  Such expansion joints are relatively limited in terms of the pressure and temperature under which they can operate.  A simple expansion joint for use under high operating temperatures and pressures includes flexible bellows extending between end plates, with tie rods connecting the end plates exterior to the bellows for limiting the spacing between the end plates.  The bellows are defined by a flexible shell in the shape of a cylinder with annular corrugations defined by a plurality of annular projections alternating with annular troughs, and rings in the troughs.          The projections are sufficiently high, the troughs sufficiently deep and the bellows sufficiently flexible that virtually the entire exterior surface of each projection contacts the entire exterior surface of the adjacent projection and the sides of the projections surround the cable when the joint is under maximum pressure.

Granted: 1991-10-29
Abstract: ABSTRACT OF THE DISCLOSURE    A technique is disclosed for the detection of cancer using nuclear magnetic resonance  (NMR).   Specifically,  NMR parameters for protons of lipid methyl and/or methylene groups are determined and compared against a corresponding value for healthy patients. In the preferred embodiments, an NMR spectrometer is employed in conjunction with a Fourier transformer to provide a spectrum for non-water components of blood, blood serum or blood plasma and the width of the methyl and/or methylene groups is measured at half-height as a determination of spin-spin relaxation time (T2) which is the  parameter used for purposes  of comparison with healthy controls.   Suppression of  the water  proton signal  is employed where necessary in order to obtain a suitable spectrum for the non-water component protons.

Granted: 1992-02-18
Abstract: ABSTRACT             The invention is both a method and a product resulting from the method, for cutting thermoplastic materials in an aesthetically pleasing fashion.   A laser is used to cut a preselected pattern in a thermoplastic material, resulting in a removable cutting being created, which is extracted from the material.          Using a contrasting color of thermoplastic material, an identical laser cutting is made.  The cutting from the first laser cutting operation is mated to the cavity created by the second laser cutting operation, resulting in a mosaic-type thermoplastic material which is pleasing to the eye.  To ensure that the by-products of combustion from the laser cutting do not contaminate the heat-sensitive surfaces of the thermoplastic material, a directed source of vacuum is applied to the cutting table to ensure by-products of combustion are directed away from the cutting field.
