Patent CA-1276610-C (CA)
Title: Gate valve
Inventor: CLARKSON CURTIS W
IPC: F16K3/02
Filed: 1986-12-02
Granted: 1990-11-20
Abstract: ABSTRACT OF THE DISCLOSURE     A  packingless  gate  valve  is disclosed which includes a housing having opposed similar  housing  halves  with resilient sleeve units  which compressibly engage each other in the valve open condition  and engage  opposite sides  of the  gate in the valve closed  condition.   Each sleeve unit has a flange on the inner and outer axial ends, with the flanges extending radially outwardly from  the sleeve body.  An encircling thin stiffening ring of harder material is bonded to the  axially outer surface of the  flange on the inner end of each sleeve, each stiffening ring being shaped with a right angle bend so as to provide both axially and radially facing surfaces for each sleeve body.  The particular configuration and position  of  the  stiffener rings has  been  found  to  function advantageously in preventing the pliable  sleeve  material  from   following  the   gate  as  it penetrates  between  the  opposed  sleeve  units.   The axially extending  portion  of  the  stiffener  rings  also  assists in aligning the  opposed sleeves  with the housing as well as with each  other.    The  gate  valve  construction  of  the present invention results  in no  leakage to the outside when the valve is fully open and no leakage  to the  outside or  past the gate internally when the valve is fully closed.

Title: Electronic generator for air purification
Inventor: STONE JUDSON F
IPC: B03C3/40
Filed: 1987-04-07
Granted: 1992-03-31
Abstract: ELECTRONIC GENERATOR FOR AIR PURIFICATION                  Abstract Of The Disclosure An electronic generator for air purification includes a molded plastic housing having a flat floor and a cover.  The housing has an air inlet, and a fan pulls air in through the inlet and blows it out through remote outlets.  Within the housing and mounted on the floor there is a concave-convex dome made of non-conductive material, and high voltage providing transformer and rectifier structure are mounted within the dome in an inaccessible position.  A negative high voltage potential is applied to the conducting concave surface to establish a negative electrostatic charge over the convex surface.  The air moving through the housing passes over this convex surface, and negative ions are produced.

Title: Process for the automatic recognition of objects liable to overlap
Inventor: JUVIN DIDIER
IPC: G06K9/48
Filed: 1987-04-13
Granted: 1990-11-13
Abstract: ABSTRACT OF THE DISCLOSURE          The invention relates to a process for the recognition of objects liable to overlap, on the basis of reference images of said objects and the image of the group of said objects.            The process consists of coding successive elementary segments, whose ends are substantially located on the contour of each image in the "learning" phase of the contour of each object and in the object recognition phase.  Pairs of characteristic segments in the contour of each image are then investigated, each characteristic segment being oriented and defined by its oriented angle, its length and its origin.  Each pair giving a good image discrimination is called a transition vector.  These vectors are hierarchized for the reference images and compared with the transition vectors of the image of the objects to be recognised.  For any object assumed to be recognised, a fine verification takes place on the elementary segments.     Application to the recognition or identification of objects and to artificial vision in robotics.

Abstract: AIRCRAFT ENGINE FRAME CONSTRUCTION          ABSTRACT OF THE DISCLOSURE A  gas  turbine  engine  of  the  type  having generally cylindrical casings defining concentric bypass and turbine discharge passages including a support   structure   in  the  turbine  discharge passage.   The  support  structure  is  cooled with low pressure compressor discharge air through a scoop  located  in  the bypass  gas  passage.   The support structure includes a plurality of radial fairings,  each  of  which  includes  a  discharge chute which is approximately perpendicular to its respective  fairing.   The  discharge  chutes  each communicate  with  the  compressor  discharge cool air  flow  in  its  respective  fairing  so  as  to provide  a  discharge  flow  in  the  form  of  a stratified  annulus  to  cool  downstream  members which are aligned with the discharge chutes.  The cooling  air  further  reduces  the  temperature of the  downstream  gases  so  as  to  reduce  the potential  for  flashback  in  the  engine.   The aerodynamic form and placement of the discharge chutes provide enhancements to the operation of the diffuser, of which the support structure is a part.

Abstract: A chromatography apparatus incorporating an improved means for connecting the ligand to the solid support is disclosed.  The apparatus comprises a chamber containing a solid support.  The solid support is a hydrophobic support.  The apparatus includes chromatography surfactants bonded to the solid support.  The surfactants comprise a polar group, a hydrophobic functional group substituted on the polar group, and a chromatographic functional group substituted on the polar group.  The hydrophobic group is hydrophobically adsorbed to the solid support so that the chromatographic functional group is bound to the solid support and available for binding to compounds which selectively bind thereto. Compositions for and methods of making the foregoing are disclosed.  The chromatographic functional group is a ligand for affinity chromatography, an ionogenic group for ion exchange chromatography, or a hydrophobic group for hydrophobic chromatography.  Hydrophobic silica particles are preferably used as the solid support, with hydrophobic polymers more preferred.  Polyalkoxy groups are preferably used as the polar groups.  Covering surfactants are preferably adsorbed to the solid support to reduce non-specific binding thereto.

Abstract: Abstract The invention relates to a process for producing microcapsules by micro-encapsulating hydrophobic oils, particularly with substances contained therein, in which the hydrophobic oil is mixed, accompanied by vigorous stirring, into an aqueous medium containing a dispersion-stabilizing com-pound, the oil-in-water dispersion obtained is adjusted acid, aminoplastic capsules are formed in the conventional manner and the aqueous fraction of the aqueous medium is removed in the usual way. The aqueous medium contains a water-soluble, cationic compound such that it forms a dispersion-stabilizing compound in interaction with the water-soluble, anionic, sulphonated melamine-formaldehyde precondensate. The micro-capsules obtained according to this process can be obtained economically without agglomerate formation in the form of dry single capsules e.g. by spray drying the aqueous capsule dispersion obtained. The invention also permits the encapsulation of random substances in dissolved and/or finely dispersed form.
