Title: Method for the manufacture of shaped bodies formed from plastics-filler mixtures having a high filler content
Inventor: TETZLAFF ERNST
IPC: B29C48/85
Filed: 1996-11-12
Abstract: A method for the manufacture of shaped bodies by extrusion moulding of plastic-filler mixtures with filler contents of more than 50% by volume, preferably from 65 to 90% by volume, by means of an extruder with a conveying input zone.  The method is restricted to use of fillers having good thermal conductivity.  For carrying out the method, initially a mixture is manufactured from molten or fluid synthetic resin and the filler and this is ground and graded after cooling. Afterwards, there is extrusion of the ground mixture or of fractions separated from this and graded.  According to a preferred variant of the method, an extruder is used for the extruding having a conveying input zone whose extrusion part consists merely of an input zone and an output zone.  According to a further variant of the method, plates are manufactured by cutting up lengthwise a tubular extrusion emerging from the mouthpiece in the extruding and the casing of the extrudate thus obtained is bent flat and this extrudate is then cut up into plate lengths.

Patent CA-2198825-A1 (CA)
Inventor: LOPEZ MORALLYS
IPC: A45C11/24
Filed: 1997-02-28
Abstract: A carrier convertible from a carrying and storage mode to a playing mode. There are two bins which, in the carrying mode, are positioned on either side of one or more boards. The bins interlock with each other and with the boards so that the wholedevice may be easily carried as a unit. The interlock may be formed from posts and holes, depressions and protrusions, etc. When a user wishes to play bingo or other similar type game, the carrier is quickly and easily converted to playing mode. The latches are disengaged to allow the two bins to separate. This frees the boards from their confinement by the interlock. There is a groove in the backs of the boards. When the boards are set up for play, the grooves are set to rest over and engageeither the low front edge of the bins, or the higher back edge of the bins. In this position, the boards provide an inclined surface for holding and displaying multiple bingo cards for convenient viewing and playing.

Patent CA-2207016-A1 (CA)
Title: Holographic reflector and reflective liquid crystal display using it
Inventor: SATO ATSUSHI
IPC: G02F1/1335
Filed: 1997-06-04
Abstract: When illumination light is externally incident on a liquid crystal display, of the incident light, light of a polarized component in one direction passes through a polarizing film to reach a liquid crystal panel. After the light reaching the liquid crystal panel is optically rotated in accordance with the display pattern displayed on the liquid crystal panel, it reaches a polarizing film. The light passing through the polarizing film enters a holographic reflector. The incident light passes through a hologram without being diffracted due to the angle selectivity of the hologram. Light passing through the hologram is regularly reflected by a metal reflective layer arranged on the back surface of the hologram to be incident on the hologram again. Incident light (reflected light) is incident on the hologram at an incident angle having a plus or a minus sign reverse to the previous incident light. The incident light matches the angle selectivity of the hologram, and is transmitted aid diffracted at a specific angle to become diffracted light. The diffracted light passes through the polarizing film, the liquid crystal panel, and the polarizing film again to reach observer's eyes as pattern display light.
