Title: Plant chitinase gene and use thereof
Inventor: MIKKELSON JORN D
IPC: A01N63/50
Filed: 1991-08-08
Abstract: ABSTRACT         A DNA sequence comprising the sugar beet chitinase 4 DNA sequence shown in Sequence 1 or an analogue or subsequence thereof is disclosed. The polypeptide encoded by the DNA sequence, also termed the sugar beet chitanase 4 enzyme, has a high antifungal activity due to a hitherto unreported bifuncitoanl catalytic activity (i.e. a chitianase and a lysozyme activity) which makes the enzyme highly effective in inhibiting the growth of chitin-containing fungi. An even improved antifungal effect is obtained when the sugar beet sugar beet chitinase 4 enzyme is used in combination with other pathogenesis related proteins, especially in combination with a second different chitinase and a .beta.-1,3-glucanase. A preferred use of the DNA sequence disclosed hererin, optionally in combination with DNA construction of genetically transformed plants, especially genetically transformed sugar beet plants, having an increased resistance to chitin-contiaining fungi as compared to untransformed plants.     829540ab.001/LS/JKM/A12/1991 07 29

Patent CA-2070457-A1 (CA)
Inventor: HILL RUSSELL J
IPC: H01J37/305
Filed: 1992-06-04
Abstract: The present invention provides an electron beam gun for an electron beam evaporation source in which a beam former shields a filament from an anode such that electrons emitted from the filament are accelerated past the anode in a ribbon-like beam. The filament is connected to a split cathode block having two sides for applying an electric current through the filament. The beam former has two sections which are separately connected to the two sides of the cathode block such that the cathode block acts as a heat sink for the beam former, and a thermal gradient  is  not  produced within the beam former  that would produce warpage and movement of the beam former.  Preferably, the  vertical  gap  is  about  0.254  mm.  to  prevent  electrons emitted from the filament from arcing through the gap to the anode.
Patent CA-2073487-A1 (CA)
Inventor: GILLEN JOHN F JR
IPC: A61H23/04
Filed: 1992-07-08
Abstract: The apparatus comprises a pad and a sequential pressure device that includes a pneumatic system and a control system.  The pad comprises a plurality of adjacent chambers extending transverse to the pad's longitudinal centerline and has a lower section with at least two chambers and an upper section with at least three chambers.          Two adjacent chambers of the lower section have approximately the same transverse cross-sectional area for about their lengths.  Each chamber of the upper section includes a right portion, a left portion and an intermediate portion which has a narrowed center portion of reduced cross-sectional area connecting with the right and left portions.  Inflation of an upper section chamber causes expansion of the right, left and intermediate portions thereof with a void created about the narrowed intermediate portion.  The method makes use of the apparatus to massage the back of a patient placed in a supine position on the pad to mobilize the spine and stretch and relax the musculature and soft tissue of the back while avoiding placement of undue pressure on the thoracic vertebrae portions of the spine which are positioned above the intermediate portions of the chambers of the pad upper section.

Title: Method of making large cross section injection molded or slip cast ceramic shapes
Inventor: NEIL JEFFREY T
IPC: C04B35/81
Filed: 1991-01-24
Abstract: A method for making essentially crack free large cross section ceramic articles by injection molding techiques comprises the use of from about 0.1 v/o to about 10 v/o fibers with the ceramic injection molding formulation followed by the injection molding, binder removal and densification steps to form an essentially crack free densified large cross section ceramic article. The fibers are softened prior to the onset of densification and incorporated into the ceramic intergranular phase. This process eliminates the component distortion during densification which would have occurred if the fibers remained in the component.

Abstract: A core component for use in a fluid-absorbing article, such as a diaper, incontinence pad, catamenial device or the like is described, which core component has a plurality of core zones comprising a zone of vulnerability positioned in said core component for maximum potential exposure to wetting, and at least one additionalcore zone arranged in an area of reduced potential exposure to initial wetting and in direct or indirect fluid receivable relation from the zone of vulnerability. The zone of vulnerability has a wadding component comprising synthetic fiber of filament and has a greater average pore size than the average pore size of the wadding component in the at least one additional core zone. When two or more additional core zones are used, the average fractional value of fiber volume-to-fiber surface area and the average pore size within the wadding components of the additional core zones decrease invalue from zone to zone with increased distance from the zone of vulnerability and with reduced risk of initial wetting. The zone of vulnerability may be further characterized by having a greater average liquid-solid contact angle than the average liquid-solid contact angle in the additional core zones. A fluid absorbing article and a method for increasing fluid receptivity, fluid storage efficiency, and reduced rewet characteristics utilizing the core component of the invention are also described.
