Patent CA-2046104-C (CA)
Title: Method of measuring the nonlinear refractive index coefficient of a bistable resonant cavity optical component
Inventor: CALVANI RICCARDO
IPC: G02F1/35
Filed: 1991-07-03
Granted: 1996-01-30
Abstract: In order to determine the nonlinear refractive index coefficient of a material which, when incorporated into a Fabry-Perot cavity has an optically bistable behaviour, the output power of the cavity is measured as a  function of the power of an amplitude-modulated optical input signal in order to obtain a hysteresis loop characteristic of the material;  the  hysteresis  loop  saturation  region  is detected, in which the phase of the electromagnetic field associated with the signal within the cavity is a linear function of the output power; the values of the phase in that region are obtained from the output and input power values, and the nonlinear refractive index coefficient is obtained from the angular coefficient of the straight line representing the phase.

Title: Gas management system for closely-spaced laydown jets
Inventor: MARSHALL LARRY R
IPC: D04H3/10
Filed: 1991-08-21
Granted: 2002-02-26
Abstract: An improvement is disclosed for reducing or even preventing interferences or interactions between adjacent, closely-spaced laydown jets utilized in a fibrous sheet laydown process. The improvement comprises positioning an inverted "V-shaped" baffle between adjacent, closely-spaced laydown jets so that the turbulent gas streams produced by each laydown jet are diverted and vented away from the area of sheet laydown on a moving collection belt. The baffle vents the fountain of gas produced by the collision of adjacent laydown jets in a cross-direction to that of the direction of belt movement.

Title: Atmospheric compensating automatic air release valve
Inventor: SABALVARO VINCENT M III
IPC: F16K24/00
Filed: 1992-01-02
Granted: 2001-03-27
Abstract: The invention relates to an air release valve and more particularly to an atmospheric compensating automatic air release valve. The invention features a valve including a second orifice which is exposed to atmosphere but always shut whereby a valve mechanism in the valve is exposed to forces which are equal and opposite to a suction force which tends to hold the valve mechanism in sealing relation to the first, air release orifice. By providing first and second orifices in accordance with the present invention, then, movement of the valve float downwardly as the liquid level goes down will cause the air vent orifice to open irrespective of the pressure within the valve.      Thus, the automatic air release. valve provided in accordance with the present invention is capable of operating under virtually unlimited pressures.

Title: Process for sulfating unsaturated alcohols
Inventor: MATTHEWS RANDALL STRYKER
IPC: B01J31/02
Filed: 1990-11-16
Granted: 1995-08-15
Abstract: The present invention is directed to a process for sulfating unsaturated alcohols using inexpensive reagents and mild reac-tion conditions. The process comprises reacting an unsaturated alcohol of the formula R-OH, wherein R is a C8-C22 alkenyl group, with an ether sulfate of the formula R1(OCH2CH2)nOSO3M, wherein R1 is a C1-C18 hydrocarbyl group, n is an inte-ger from 1 to 10, and M is an alkali metal, to form an unsaturated sulfate; said reaction being carried out in the presence of a catalytically effective amount of an acid catalyst. The mole ratio of unsaturatedd alcohol reactant to ether sulfate ranges from about 0.5:1 to about 2:1. In this process the sulfation occurs primarily at the hydroxyl goup of the unsaturated alcohol, with minimal sulfation at the olefinic moiety of said alcohol.

Granted: 2000-10-31
Abstract: Le système comporta au moins un dispositif d'une détection de concentration critique d'eau dans la turbomachine et un dispositif permettant l'augmentation automatique du régime de rotation de la turbomachine. Le dispositif de détection est basé sur la mesure de l'élévation de la température de l'air au passage du compresseur et sur la comparaison de cette élévation de température à celle qui est considérée comme critique pour le fonctionnement de la turbomachine pour une vitesse de rotation donnée. Lorsque l'élévation de température mesurée est inférieure à l'élévation de température critique, le dispositif de détection envoie un signal au dispositif d'élévation du régime de rotation de la turbomachine, ce dernier comprenant un circuit à prépondérance maximum, intégré dans la boucle de régulation de la vitesse de rotation du moteur. La valeur la plus importante pour l'élévation du régime moteur, sera prise en compte par le circuit à prépondérance maximum qui délivrera au doseur de carburent l'information correspondante.

Title: Packaging system
Inventor: GEORGE MICHAEL
IPC: B65D77/00
Filed: 1992-10-30
Granted: 2004-04-06
Abstract: A packaging system is provided for a plurality of packages which are vulnerable to damage when cut into by a sharp instrument. The packaging system includes a rectangular container enclosing all of the packages and being formed of a rectangular lid and a rectangular tray, both of which have four peripheral sides of equal height. The lid and the tray come together in a container configuration, preferably in a mating and nonoverlapping configuration, to form the container. A shrink wrap material is applied about the container and shrunk into engagement therewith so as to encircle the container in three dimensions and thus hold the lid and tray in the mating configuration. The shrink wrap material is suitably weakened to allow a manual tearing of the shrink wrap material to release the lid and hence open the container. The shrink wrap material is weakened by a longitudinal slot located adjacent the lid and extending from one side of the lid to an opposite side and two paired series of weakenings in the shrink wrap material. Each respective paired series extends laterally away from the slot and each paired series has one series of weakenings separated from the other series and provided along the lid adjacent a respective side. Preferably, the packages are rectangular and arranged in two rows in the container, and selected sides include apertures therein which together provide a view of each one of the packages.

Title: Method for making a composite to carbon steel joint
Inventor: LOPEZ ANTONIO
IPC: B23K9/235
Filed: 1993-01-29
Granted: 1996-10-22
Abstract: An improved method for making a composite tube (10) to a carbon steel tube (16) joint or a composite tube (10) to a carbon steel header (50) joint is achieved by specially preparing the composite tube (10) by removing the cladding (12) from one end (24) to a predetermined length to provide base carbon steel material (14).  The end (24) of the composite tube has cladding (12) tapered at a predetermined angle.  This end (24) is then expanded.  The composite tube (10) is then welded to the carbon steel tube (16) with fewer weld passes while also eliminating the stainless steel weld pass.

Title: Method for separating sheets of paper stacked in reams and device for implementing this method
Inventor: WYSSMULLER PHILIPPE
IPC: B65H1/00
Filed: 1993-03-04
Granted: 2001-05-15
Abstract: The method consists, while the ream is applied against a curved surface, in exerting pressure forces against the outer sheet of said ream, along a line of application parallel to the generatrices of the curved surface, moving this line over the entire length of the ream, and beyond each of the edges of the sheets, thereby releasing the sheets. The intensity of the pressure forces enables the sheets to be kept against the curved surface and the speed of movement of the line of application is adjusted in order for the released sheets successively to move away from the remaining curved sheets, thereby re-establishing a plane ream, this reformed ream being jogged.
