Patent CA-2110851-A1 (CA)
Inventor: CAROLA ARMAND
IPC: B67D3/00
Filed: 1993-12-07
Abstract: A device for preventing a "gas-lock" when a liquid is transferred by gravity from a first container to a second container and vice versa, each container having one aperture through which a fluid matter may flow and the apertures being connectable together by first connecting means provided with channels, the containers and channels when connected together defining a closed system filled with at least one liquid and at least one gas, a first of the channels essentially defining a transfer channel for the liquid and a second of the channels essentially defining a venting channel for the gas, each of the channels having opposite ends with one end thereof substantially positioned near a portion of the first container that is substantially close of the aperture of the first container. This device comprises a hollow casing defining a reservoir of given capacity and having a lower portion and a set of three openings, that is a first and a third openings substantially positioned at the lower portion of the casing and a second opening positioned near a bottom of the reservoir; second connecting means for connecting a corresponding end of the second channel with the second opening; a third channel having opposite ends, one end being positioned near a portion of the first container that is opposite to the aperture of the first container; third connecting means for connecting the opposite end of the third channel with the first opening; a check valve; fourth connecting means for connecting the check valve with respect to the third opening and for selectively preventing or allowing the liquid contained in the first container to pass through the third opening; the capacity of the reservoir being sufficient to collect when the first container is turned upside-down to have its third channel above the reservoir, all the liquid that may fill this third channel and allow inside the reservoir a free passage for the gas between the first and second openings. Also relates to an arrangement containing the device and a method use.

Abstract: Un dispositif d'assemblage pour maintenir ensemble des panneaux par leurs arêtes. Chaque panneau a un axe longitudinal, deux surfaces opposées, et au moins une arête munie d'un jeu de tenons et de mortaises parallélépipèdiques façonnés de manière particulière et destinés à s'imbriquer d'un seul mouvement avec un jeu correspondant de tenons et de mortaises façonnés et disposés sur une arête adjacente d'un autre panneau. Les panneaux une fois imbriqués peuvent être bloqués à l'aide d'une clef insérable dans une cavité qui s'étendent centralement entre les arêtes adjacentes. Un avantage du dispositif est qu'une fois la clef insérée, aucun espace libre n'est présent à l'intérieur de ce joint et la surface de contact entre les pièces est maximum. Cette grande compacité du joint induit une grande résistance aux chocs, aux tiraillements et aux pressions de toutes sortes auxquels il pourrait être soumis.

Title: Simultaneous analog and digital communication using fractional rate encoding
Inventor: BETTS WILLIAM L
IPC: H04L27/34
Filed: 1994-04-22
Abstract: Simultaneous Analog and Digital Communication Using Fractional Rate Encoding Abstract Digital data is encoded using a modulus m converter 700 to produce fractionally encoded words, where m is the nearest integer larger than 2c and c is a noninteger. The fractionally encoded words are mapped into a symbol constellation having m symbols to produce a two dimensional data signal 62, 63. The data signal is added to a two dimensional analog signal, which was obtained by encoding an input analog signal, to produce a combined two dimensional signal. The combined signal is modulated using QAM and then transmitted over a communication channel.(FIG. 17).

Title: Virtual reality imaging system
Inventor: MYERS WILLIAM L
IPC: G06T15/10
Filed: 1993-09-27
Abstract: The virtual reality imaging system (10) takes a multidimensional space that contains real world objects and phenomena, be they static or dynamic in nature, and enables a user to define a point and/or a path through this multidimensional space. The apparatus (10) then displays the view to the user that would be seen from the point and/or path through the multidimensional space. This view is filtered through user definable characteristics that refine the real world phenomena and objects to a perspective that is of interest to the user. This filtered view presents the user with a virtual view of the reality contained within this multidimensional space, which virtual reality presents data to the user of only objects, views and phenomena that are of particular interest to the user.

Title: Apparatus and method for shaving
Inventor: GREGORY HARBERT S
IPC: B26B21/44
Filed: 1994-08-19
Abstract: An improved apparatus and method for shaving including a rectangular dispenser detachably connected to a razor handle and a disposable blade carrying head.  The dispenser includes a reservoir that may be divided into open compartments that are in direct communication with separate conduits in the blade head that extend adjacent to the blades carried by the disposable head.    The method for using the aforestated improved apparatus for shaving includes the steps of applying a water soluble lubricant to the user's face and allowing the lubricant to dry into a film, applying shaving foam to the film, holding the razor and reservoir beneath a running faucet to fill the same and stroking the blades across the user's face.  When the blades are placed against the user's face, the water flows from the reservoir onto the blades and the user's face adjacent thereto to reactivate the lubricant just prior to the passage of the blades thereover.

Title: Method and apparatus for separating wood fibres from other fibres in fibremat residues
Inventor: CHOW SUEZONE
IPC: D01G11/00
Filed: 1994-10-03
Abstract: Residues from fibremat materials are broken down and separated into wood fibres and other fibres so that the fibres may be recycled.  If the fibremat residues are not recycled, they present a disposal problem due to the uncured resins that become toxic waste.  The fibremat residues are cut and separated by rotating cutting heads within a cutting and separating chamber.  The wood fibres, being the heavier fibres, settle out, pass through a screen into a collection chamber and the lighter textile fibres are sucked out of the cutting and separating chamber with a vacuum system.
