Patent CA-2045287-A1 (CA)
Inventor: FRANCOIS AUBIN
IPC: G03B21/12
Filed: 1991-06-21
Abstract: : Notre invention est un procédé permettant de projeter des images réelles tridimensionnelles à partir d'un support bi-dimensionnel (image infographique, dessin, diapositive, film, etc. ). Ce procédé d'imagerie 3D est basé sur l'utilisation conjuguée de ces deux technologies, soit: 1- La projection d'images anamorphosées sur un écran tridimensionnel (écran conique: hémisphère, cône, parabole); 2- un dispositif catoptrique utilisant deux miroirs paraboliques concaves de façon à produire une image réelle en trois dimensions visible sur 360.degree.. Grâce aux transformations géométriques (anamorphique) de l'image et aux capacités qu'ont les miroirs concaves de projeter des images 3D dans l'espace réel, notre procédé d'imagerie permet de rassembler les conditions d'observation et d'utilisation suivantes: - le système projette dans l'espace une image tridimensionnelle en couleur et pouvant être animée; - l'image est visible sur 360.degree. horizontalement et celle-ci peut être perçue par plusieurs personnes à la fois; - l'image peut être traitée, en temps réel, par l'intermédiaire d'un système informatique (déplacée, orientée, transformée, filtrée, etc.); - le procédé ne nécessite pas le port d'appareils spéciaux reliant l'utilisateurau système, ni lunettes à cristaux liquide ou polarisantes, ni gants électroniques, etc.. - le procédé permet la reproduction illusoire de la parallaxe de mouvement, c.a.d. qu'il est possible d'observer les éléments représentés à partir de plusieurs point de vue différents et d'observer des variations d'apparences correspondant aux déplacement de l'observateur. Alors que tout les autres dispositifs de miroirs concaves voués à la projection d'images réelles nécessitent l'utilisation d'un objet modèle, notre procédé d'imagerie 3D est complètement différent de ceux-ci par le fait qu'il permet d'obtenir des images 3D à partir d'une projection utilisant des support 2-D traditionnels. De plus, il se distingue aussi des techniques d'images en trois dimensions comme la stéréoscopie ou l'holographie, et ce, tant dans son procédé (miroirs concaves et projections anamorphiques) que dans ses effets perceptuels (illusion de tri-dimensionnalité, angles de vision, etc.). Les images 3D que nous obtenons grâce à notre procédé sont homothétiques à l'objet représenté, elles recréent toutes les apparences naturelles d'un objet réel visible sur plusieurs angles et présente, grâce à l'utilisation de l'informatique, des possibilités d'interactivité.

Sea water is introduced into the container during and after trash-filling to sterilize the trash therein. The used sea water is pumped out of the container to a waste water treating apparatus to avoid pollution. After filling, the container is enveloped to form a sealed unit, and is then used to fill an area of sea to be reclaimed. The plastic layer is preferably made of acidproof and alkalineproof material to insure an effective and long lasting sealing.

Patent CA-2076770-A1 (CA)
Inventor: PAOLINI ANTHONY L
IPC: G03G15/02
Filed: 1992-08-25
Abstract: In a single pass, tri-level imaging apparatus, erroneous voltage readings of an Electrostatic Voltmeter (ESV) which has become contaminated by charged particles (i.e. toner) are negated by using two ESVs.         During each cycle up following a normal cycle down, a pair of Electrostatic Voltmeters (ESVs) are utilized to measure the voltage level on a portion of relatively uncharged portion of a photoreceptor (P/R). Using one of the ESVs, which is less prone to contamination, as a reference, the zero offset of the other is adjusted to achieve the same residual P/R voltage reading. The difference in the readings which is due to toner contamination is the zero offset between the two ESVs. The offset is used to adjust all subsequent voltage readings of the ESV until a new offset is measured.

Abstract: ABSTRACT OF THE DISCLOSURE: Spray coating, particularly flat spray coating of circuit boards. Applicant's method of discrete conformal coating eliminates "railroading" at the edges of the flat spray web and assures precise control of the amount of coating material placed on the circuit board surface, as well as on the varying and complex circuit board components. The method includes pressurizing the coating; longitudinally advancing a surface to be coated, such as a circuit board, beneath the coating, while simultaneously feeding the coating onto the advancing surface as a plural series of aligned droplets extending transversely across the advancing surface. The feeding of coating is triggered "ON/OFF" so as to define longitudinally the series of droplets feeding onto the advancing surface.

Title: Rolled tissue dispenser
Inventor: FRAZIER ALAN D
IPC: A47K10/38
Filed: 1993-05-12
Abstract: ABSTRACT OF THE INVENTION       A tissue dispenser for dispensing rolls of sanitary tissue wound on a core having a main housing having a rear wall which is adapted to be mounted to a vertical surface.  A spindle projects into the main housing substantially perpendicularly from the rear wall to support a roll of tissue within the main housing.  A door is pivotally mounted to the front of the main housing such that the roll of tissue can be substantially enclosed therein with an exit port at the base of the dispenser through which the tissue is dispensed.  The door includes a knob housing in which a rotatable knob resides.  The rotatable knob is spring biased such that it normally resides in a position away from the roll of tissue. Extending from the knob are teeth or cogs.  When the tail of tissue is not presented through the exit port of the dispenser, a user can retrieve the tail by depressing the knob against the biasing of the spring such that the teeth or cogs engage the roll of tissue and/or the spindle.  By rotating the knob in a depressed position, the roll of tissue also rotated causing tissue to unwind from the roll and descend through the exit port.
