Patent CA-1292590-C (CA)
Title: Method for injection molding with improved mold primer
Inventor: KELLY BRIAN M
IPC: C08J5/00
Filed: 1987-01-08
Granted: 1991-11-26
Abstract: Abstract of the Disclosure An in-mold coating which contains a preferentially adhesive resin also serves simultaneously as a mold release agent, and results in RIM (reaction injection molding) plastic articles whose surfaces virtually mirror the mold surface.   Such a coating leaves no appreciable residue whatsoever on the mold surface during a production run of a large   number   of   articles,   obviating   the   previously encountered need to clean the mold each time a conventional mold release agent was introduced, each time an article was molded.     The  preferred  resin  in  the  coating  is  a hydroxylated vinyl  chloride-vinyl  acetate  copolymer  (VAGH resin).

Title: Adaptive speech feature signal generation arrangement
Inventor: ROSENBERG AARON EDWARD
IPC: H03M7/30
Filed: 1987-03-25
Granted: 1995-12-05
Abstract: A signal processing arrangement uses a codebook of first vector quantized speech feature signals formed responsive to a large collection of speech featuresignals. The codebook is altered by combining the first speech feature signals of the codebook with second speech feature signals generated responsive to later input speech patterns during normal speech processing. The first set of vector quantized feature signals are thereby adaptively modified to second speech feature signals obtained from normally processed speech patterns.

Patent CA-1290514-C (CA)
Inventor: BRAEGER HORST
IPC: A22C25/18
Filed: 1987-07-06
Granted: 1991-10-15
Abstract: ABSTRACT OF THE DISCLOSURE:     The invention aims at improving an apparatus for dividing fillets into portions, such as, for example, tails, loins and possibly centre pieces by effecting the necessary dividing cuts whilst simultaneously and automatically safe-guarding an adaptation to the particular fillet dimensions or other optically striking features.  To this end, a cut-ting mechanism arranged above a fillet supplying conveying surface and constituted by at least one cutting member is suggested, whose circular knife has a flattened portion, which, when facing the conveying surface, offers a passage position of the circular knife and by a well defined rota-tion makes it possible to bring the knife into the cutting position.  The cutting members are controlled by computing the dimensions and/or optically striking features of a fil-let image obtained by means of a video camera and supplied to a computer.

Title: Heat-intercepting garment or blanket
Inventor: ST OURS THOMAS A
IPC: A62B17/00
Filed: 1987-08-21
Granted: 1991-11-19
Abstract: ABSTRACT     A  heat-intercepting  shield  or  shroud  in  the  form of a garment, blanket or belt having on  at least  one surface thereof one or more pockets to receive replaceable packets of refreezable material which absorb large  quantities of  heat as  the material melts.   Each pocket  has two  coextensive fabric layers stitched together to form opposite pocket walls.   Over  the entire pocket area and  next to  one wall  are coextensive layers of reflective material  and  of  insulating  material.    These  materials  are flexible and  one or  both are  stitched next  to that one pocket wall in seams at  the  edge  of  the  pocket  so  that  both heat reflection and  retardation of heat flow by the insulation occurs over the entire pocket area.  Between the layers of insulation and reflective materials  and the  other pocket wall is a space for a heat absorbing packet or packets of frozen gel.  The  side of the shield or  shroud with the packet or packets is placed toward the object  to  be  cooled   or  protected   from  external  radiant, conductive or  convective heat.   The  garment or blanket of this invention achieves practical protection for a worker in unusually hot  environmental  conditions  and  is  very  durable, low cost, easily  laundered,  comfortable  to  wear,  and  provides  a very convenient  way  to  replace  refreezable  heat absorbing packets therein under working conditions.

Title: Microwave/steam sterilizer
Inventor: COURNEYA CALICE G
IPC: A61L2/20
Filed: 1987-10-30
Granted: 1992-02-04
Abstract: TITLE    Microwave/Steam Sterilizer ABSTRACT OF THE DISCLOSURE   In the most preferred form, a microwave/steam sterilizer and its method of operation are disclosed including a waveguide having a waveguide conduit including a terminal aperture located one quarter wavelength from the bottom of a water reservoir and including a series of subapertures spaced in the range of one quarter wavelength from each other.  The waveguide further includes a mitered corner moveable to shift the microwave standing waves to communicate with the terminal aperture and/or the series of subapertures in response to-conditions sensed in the working cavity.  The waveguide and the walls of the working cavity are angled with respect to each other to avoid reflection of microwave energy back to the microwave energy generator.  The sterilizer hydrates potential pathogens and subjects them to relatively uniform electromagnetic energy without arcing and without self-destruction of the microwave source by reflected microwave energy.
