Patent CA-2073490-C (CA)
Title: Modeling dough
Inventor: MARIANO KAREN M
IPC: C08K9/02
Filed: 1992-07-08
Granted: 2000-02-01
Abstract: A modeling dough comprising gelled poly(vinyl alcohol), water and a filler provides a dough resistant to flaking, cracking, and crumbling. In the disclosed invention, the poly(vinyl alcohol) resin is gelled, thereby providing a water-based resin system that is not sticky yet very ductile. Prior to drying, the dough also exhibits the properties of bounceability and the ability to pick up newsprint. After the dough is air-dried, the poly(vinyl alcohol) resin serves to bind the components into a solid, durable product. The filler accounts for a large portion of the volume of the dough, so the overall volume is not greatly affected by water loss upon drying.      The dough is water-based and easy to wash from skin, carpets, and other surfaces. Dyes and pigments can be easily incorporated into the formula The dried product is sandable, carveable and paintable.

Title: Method for the preparation of halide glass articles
Inventor: FRANCE PAUL WILLIAM
IPC: C03B37/012
Filed: 1991-07-09
Granted: 1997-07-29
Abstract: Halide glass articles, e.g.rods, tubes and preforms for making fluoride glass fibres, are prepared by melting and/or casting the articles under a low pressure, e.g. 0.01 to 500 mbars and, during the low pressure regime, a gas flow rate of between 0.01 to 100 litres/min (measured at NTP) is maintained. It has been found that subjecting the melts to a low pressure reduces the attenuation of the fibre which eventually results from the melts.

Abstract: A beam (10) adapted for implantation within a bone is able to support bending and torsional loading forces applied there-to. The beam (10) has a stiffness defined by a modulus elasticity, which stiffness varies along the length (18, 20, 22) of the beam (10) to match the corresponding stiffness of the cortical bone adjacent the beam (10) after implantation within the bone. The beam (10) is made from an elongated core (12) formed of continuous filament carbon fibers embedded in a thermo-plastic polym-er matrix with the carbon filaments extending in a direction substantially parallel to the longitudinal axis of the beam (10). Enca-sing the core is a filler (14) molded to the core (12), which filler (14) is made up of the same thermoplastic polymer as the core (12) but contains no reinforcing carbon fibers. The filler (14) provides the prosthesis (10) with a shape generally conforming to the desired shape of the final prosthetic implant. A sheath (16) formed of carbon reinforced filament fibers embedded in the thermoplastic polymer is wound in spiral formation around the filler (14) and molded thereto. The winding angle and the sheath (16) thickness along the beam (10) may be varied to vary the modulus of elasticity to match that of the cortical bone adjacent thereto.

Abstract: Stereoscopic images are presented using so-called "alternate eye" projection while blocking the viewer's respective eyes alternately and in synchronism with the display of images so that the viewer's left eye sees only left eye images and the right eye sees only right eye images. Blocking is effected using electro-optic liquid crystal shutters each of which has a front linear polarizing filter with a defined axis of polarization. The respective shutters for the viewer's two eyes are oriented so that the said defined axes of polarization are at an angle with respect to one another. The projected images are linearly polarized so that the left eye images are polarized along an axis that is parallel to the defined axis of the electro- optic shutter for the viewer's left eye and the right eye images are polarized along an axis parallel to the defined axis of the electro-optic shutter for the viewer's right eye. The invention significantly reduces perceptible ghosting even where high contrast images are projected, such as dark figures against a white background.
