Patent CA-2217874-A1 (CA)
Inventor: BROOKS S HUNTER W
IPC: D21B1/06
Filed: 1996-04-19
Abstract: Cette invention concerne un procédé de fabrication de fibres de lignocellulose pouvant éventuellement être revêtues d'un thermoplastique adéquat. Les matériaux de base peuvent être choisis parmi une grande variété de produits généralement non recyclables contaminés faits de bois, de papier et/ou de plastique. Un mélange se composant du matériau de lignocellulose préféré, lequel se caractérise par une teneur en humidité relativement basse, et des thermoplastiques requis, est raffiné et broyé finement dans une atmosphère de vapeur à une température, une pression et pendant une durée suffisantes pour ramollir tant la lignine contenue dans les copeaux de bois que le polymère thermoplastique. La température de l'atmosphère de vapeur est relativement élevée à cause de l'utilisation de copeaux de bois secs qui n'engendrent pas de dégagement de vapeur excessif durant le chauffage. Le broyage fin de ce mélange se fait par passage de ce dernier entre deux disques de raffinage en rotation inverse dans l'atmosphère de vapeur sous pression et à température élevée. Lors de leur passage à travers les deux disques de raffinage en rotation, les copeaux de bois sont abrasés de manière continue afin d'obtenir la formation de fines fibres du matériau de lignocellulose, tandis que les thermoplastiques ramollis sont simultanément raffinés afin d'adhérer uniformément autour de chacune des fibres de lignocellulose abrasées. Après leur passage entre les disques de raffinage, les fibres sont refroidies, donnant lieu à la formation de fibres de lignocellulose ayant un revêtement uniforme, lesquelles peuvent être ensuite utilisées pour obtenir une gamme de produits faits de panneaux de fibres consolidés, par exemple, lors d'opérations de pressage à chaud ou de pressage à froid.

Patent CA-2222859-A1 (CA)
Inventor: AMBROSY ANTON
IPC: G02B6/12
Filed: 1997-12-19
Abstract: The invention relates to a substrate (SUB) serving as a support, an optical waveguide (OWL) disposed on the substrate (SUB) and electrical conduction paths (ELB). Conventionally, the electrical conduction paths are placed on a thin insulating layer covering the substrate. According to the invention, the electrical conduction path (ELB) are routed on top of the surface (WOF) of the optical waveguide (OWL). This provides an improved insulation of the electrical conduction paths (ELB); moreover, the substrate surface is better utilized. Preferably, the electrical conduction paths (ELB) which are placed in ramp-like recesses (RA), are routed from the substrate surface (SOF) upwards to the surface (WOF) of the optical waveguide (OWL). The invention can be employed most advantageously proximate to laser bars where several conduction paths which are combined to form coplanar electrical waveguides, are arranged in a tight space.

Patent CA-2228908-A1 (CA)
Title: Distillation method
Inventor: MADSEN POUL ERIK
IPC: C12H6/04
Filed: 1998-02-05
Abstract: A fusel oil is an alcohol or a mixture of alcohols having more than two, typically four or more, carbon atoms, whose presence in alcoholic solutions may be undesirable on account of its characteristic effect on taste and/or aroma. By reducing the temperature of alcoholic aqueous media containing fusel oil, the solubility of the fusel oil in the solution may be reduced, to the point where it no longer remains in solution. The fusel oil being lighter than aqueous alcohol, the medium separates into two phases, and the fusel oil phase may be removed. A better separation of fusel oil from the alcoholic aqueous phase is thus obtained than is possible through conventional dilution processes.

Patent CA-2249047-A1 (CA)
Title: Composite rollers for continuous-belt drilling mud separation unit
Inventor: WILLIAMS J TERRELL
IPC: B07B1/50
Filed: 1998-09-29
Abstract: A pair of cylindrical composite rollers formed of a metallic drum having a thick outer elastomeric layer are mounted transversely in a rectangular frame of a drilling mud separation unit over which a wide endless-loop chain-link belt is driven in a continuous loop moving along the longitudinal axis of the frame. The drive roller has a plurality of axially spaced circumferential rows of radially extending teeth that are machined in the surface of the elastomeric material. The endless belt is formed of a plurality of laterally adjacent jointed links hinged together by transverse rods. As drilling mud or drilling fluids are conducted onto the moving belt, liquids and particles smaller than the openings in the belt pass through the openings and liquids and particles larger than the openings are transported on the moving belt and are discharged off of one end as the belt completes its path. The teeth of the drive roller are sized and spaced to receive and engage the plurality of laterally adjacent jointed links of the wide belt and are of sufficient length to protrude slightly beyond the outer surface of the links as they pass around the front drive roller to dislodge gumbo and other large solids which may otherwise stick in the openings of the links and clog the belt. The elastomeric roller surfaces and teeth reduce wear and prevent metal-to-metal contact and sparking.

Patent CA-2262488-A1 (CA)
Title: Multidimensional cellular mobile telecommunication system
Inventor: JONES STEPHEN S
IPC: H04B7/185
Filed: 1997-08-01
Abstract: The multidimensional cellular mobile telecommunication system extends the usage of existing cellular mobile telecommunication radio frequencies allocated for ground-based communications to non-terrestrial mobile subscriber stations by adding an overlay of non-terrestrial cells of predetermined geometry and locus in space to the existing ground-based cellular cell site network. The polarization of the signals produced by the non-terrestrial antenna elements is a polarization that is different than and preferably substantially orthogonal to the polarization of the cellular radio signals produced by the ground-based antennas, such as a horizontal polarization, to thereby minimize the possibility of interference with the vertically polarized ground-based radio signals. Furthermore, the control signals exchanged between the non-terrestrial mobile subscriber stations and the non-terrestrial cell site controller are architected to avoid the possibility of interference with ground-based cell site transmitter-receiver pairs. In particular, the control channels used for the non-terrestrial mobile subscriber stations are selected such that the control signals transmitted in these channels are unrecognizable to the ground-based mobile subscriber stations and cell site transmitter-receiver pairs, so that even if broadcasts from a non-terrestrial mobile subscriber station reach a ground-based mobile subscriber station or cell site receiver, they cannot be interpreted and are rejected out of hand.
