Patent CA-2155120-A1 (CA)
Title: Expression of protective antigens
Inventor: MUNN EDWARD
IPC: C12N5/10
Filed: 1994-02-04
Abstract: The invention provides a method for the expression of an enzyme antigen which in nature is parasite gut membrane bound enzyme or a fragment thereof having similar enzyme and/or antigenic activity, wherein mammalian host cells are transfected with a vector adapted to express said enzyme antigen or fragment thereof, characterised in that prior to transformation the host cells are substantially free from endogenous enzymes having (a) the same function and (b) the same cell membrane integration or lack of integration, as said parasite enzyme antigen or fragment thereof.  Such a method is particularly useful for the expression of helminthic integral membrane aminopeptidase antigens.
Patent CA-2155258-A1 (CA)
Title: Frequency routing device having a spatially filtered optical grating for providing an increased passband width
Inventor: DRAGONE CORRADO
IPC: G02B6/293
Filed: 1995-08-03
Abstract: An optical apparatus includes at least one input waveguide and a first free space region connected to the input waveguide.  A first plurality of waveguides is connected to the first free space region.  An optical grating, which is connected to the first plurality of waveguides, includes a plurality of unequal length waveguides that are divided into at least three waveguide groups. Adjacent waveguides that belong to the same group have a substantially constant path length difference between them while adjacent waveguides belonging to different groups of waveguides have a path length difference between them that differs from the constant path length difference by an odd integer multiple of one-half a preselected wavelength. A second plurality of waveguides is connected to the optical grating and a second free space region is connected to the second plurality of waveguides.  Atleast one output waveguide is connected to the second free space region. As a result of this arrangement, this optical apparatus has a spectral efficiency which is maximized by providing a relatively wide passband and a relatively narrow channel spacing for a given crosstalk level.

IPC: E04B2/56
Filed: 1995-08-23
Abstract: A generally flat structural panel includes a center foam core and opposed outer facings, or sheets, with a metal insert disposed about and attached to the edges of the core and at least one of the outer facings.  The metal edge insert has as objects:  providing high strength for the insulated foam panel; eliminating the need for structural members such as studs which act as thermal conductors; and facilitating coupling between adjacent panels, ceilings and floors using various connection arrangements.  A lateral surface of the foam core may be provided with a linear array of recesses, or grooves, and a facing is attached to that surface in the field to permit electrical wire routing in the recesses or metal strips may be attached to the surface of the core and adapted for secure attachment to a facing such as of drywall to provide a space between the foam core and drywall sheet for wire routing.  A spline having an insulating core and a pair of outer facing metal strips extending the length thereof is inserted in the facing grooved edges of adjacent panels as best shown in FIGS. 35 and 36.  The spline is affixed to the panel edges by means of a structural adhesive.
Patent CA-2156909-A1 (CA)
Title: Method and apparatus for producing molded food pieces
Inventor: YATES ROBERT L
IPC: A23P1/10
Filed: 1994-02-24
Abstract: Input food is extruded between a pair of counter-rotating wheels (26, 28) whose outer surfaces define mold cavities (30, 32). The deposited input food is molded into pieces having desired shape by compression between aligned, counter-rotating mold cavity pairs (30, 32). Preferably, the input food is heated prior to molding to prevent irreversible set up, and the wheels (26, 28) are chilled to cause deposited food to set up as it is compressed and carried between aligned, chilled mold cavities (30, 32) from a loading station to a release station. After the input food is molded and set up into pieces, the rotating cavities separate at a release station, allowing the molded pieces to fall away from the wheels (26, 28). To ensure ejection of all molded pieces from the cavities (30, 32) before refilling, it may be desirable to mist the empty cavities with a non-toxic release agent such as glycerine.

Title: Means for filtering and fractionation of suspensions containing fibres, fibre fragments, fines and other particles
Inventor: FONGEN SIGURD
IPC: D21D5/02
Filed: 1993-04-16
Abstract: The invention concerns an apparatus which is capable of performing a continuous, self-cleaning mode of operation for filtering and fractionation of suspensions containing fibres, fibre fragments, fines and other particles. For filtering and fractionation is applied a continuous, perforated and electrolytically produced metal foil, with perforation holes in the order of 10 - 100 µm and foil thickness of same order. Open area varies between 5 % and 40 %. The suspension is jetted onto the metal surface by high pressure and velocity, whereby the filtrate is hurdled through the perforated foil whereas the solids which are sorted out are being retained on the foil surface and is continuously removed from same. A slow, oscillating movement causes a continuous cleansing of the perforation holes.

Title: Filter press for filtering suspensions, especially sewage sludge
Inventor: PONOMARENKO VIKTOR
IPC: B01D25/127
Filed: 1995-12-19
Abstract: A filter press for the filtration of suspensions has a frame, a support plate, a pressure plate mounted in the frame and a set of vertically arranged filter plates between the support plate and the pressure plate. The filter plate is provided with a filter fabric on the side that removes the liquid and collects the solids. The filter fabric runs over two rollers that are so positioned relative to each other and relative to the fabric that an S-configuration for the removal of filter cake is imposed on the filter fabric.      A pressure application device presses the filter plates together. Spray nozzles for cleaning the filter fabric are combined with the rollers for the removal of the filter cake. Two such rollers are provided for each filter fabric of the respective filter plate and each filter fabric is of the single layer kind to reduce filter fabric consumption.      The single layer fabric also reduces the filtering resistance, thereby increasing the capacity of the filter press. The lower and upper edges of the filter fabric are secured to the respective edges of the filter plate, and the rollers for the removal of the filter cake are moved up and down by a lifter.
Patent CA-2165769-A1 (CA)
Inventor: HUBESCH BRUNO ALBERT JEAN
IPC: B01J23/44
Filed: 1994-06-08
Abstract: The present invention describes an alternative reaction path for the making of quaternary ammonium esters for fabric softening. The process starts from a chloroepoxide which is reacted with ammonia and water to form a primary amino polyol. The process continues as reductive alkylation of the primary and then secondary amine with aldehydes to provide an intermediate tertiary amino polyol. The first part of the process is followed by the traditional esterification and quaternisation steps known in the art for making quaternized ammonium fabric softening compounds.
