Title: Magnetized pre-wound sideless bobbins
Inventor: SCHOECK VINCENT E
IPC: A61K9/22
Filed: 1999-12-16
Granted: 2007-07-10
Abstract: Magnetized bobbin cores (10-1) are preferably wound with sewing thread to obtain sideless, pre-wound bobbins that have beneficial draw-off tensions, draw-off tension uniformity and overspin characteristics.  The pre-wound sideless bobbins (10-1) may thus be satisfactorily used in lock stitch sewing applications due to improved uniformity of draw-off tension combined with reduced bobbin overspin. The magnetized pre-wound sideless bobbins (10;1) are also especially well suited for end-use sewing applications where automatic bobbin changing equipment is employed. Most preferably, the core is a cylinder formed of thermoplastic or thermoset material in which magnetized particles are dispersed.

Abstract: This application relates to improvements to long vertical shaft bioreactors for the aerobic biological treatment of wastewater and aerobic digestion of biodegradable sludges. The invention comprises a flow control device (100) and method which improves hydraulic flow, inter-zonal mixing and gas transfer in such bioreactors. The flow control device (100) includes a ported upper plate (102) which is mounted in an upflow chamber (24) of the bioreactor and a lower plate (104) located below the upper plate (102) at the jucture between mix and plug flow zones of the bioreactor (102) which are in fluid communication.      At least some of the ports (108) in the upper plate (102) are fitted with adjustable valves (110) for regulating the flow of liquor therethrough and hence the size of a hydraulic head loss imposed by the flow control device (100). Preferably the upper plate (102) is mounted at a location in the upflow chamber (24) upstream from the inlet (30) where influent is discharged into the bioreactor (10). The flow control device (100) reduces the circulation velocity of the liquor in an upper circulating zone of the bioreactor and also provides a physical burner substantially restricting inter-zonal mixing between the mix (D) and plug flow zones.

Title: Planar waveguide switch and optical cross-connect
Inventor: THACKARA JOHN I
IPC: G02F1/13
Filed: 2001-10-09
Granted: 2009-09-08
Abstract: A planar waveguide integrated optic switch (10)suitable for use in optical cross-connect applications. A narrow trench (13) in the planar waveguide core layer (12) is filled with a liquid crystal (14) material possessing positive birefringence. When held at a temperature a few degrees above the clearing point, the liquids crystal's isotropic refractive index is matched to that of the core layer allowing nearly complete optical transmission (17C) through the switch. When held at a temperature a few degrees below the clearing point, the liquid crystal's ordinary refractive index is lower than that of the core layer and both polarizations of the incident optical radiation are totally reflected (17b) from the trench. When coupled with planar waveguide beam expanding and refocusing elements, arrays of the switches can be used to form an optical cross-connect capable of fully interconnecting linear arrays of single- or multi-mode optical fibers with very low optical loss. By controlling the liquid crystal temperature at more than one location along the trench, the switch can be configured to operate as a variable attenuator.

Abstract: Dans la présente invention, un système (300) d'apport de fluide comprend un débitmètre massique de type Coriolis (200), une pompe (221), une soupape de recirculation (222) et/ou une soupape de surpression (220). Le système d'apport de fluide empêche de mesurer un écoulement de fluide polyphasique sans qu'il soit nécessaire d'utiliser un régulateur de pression et un filtre à tamis. Le débitmètre massique de type Coriolis mesure la valeur de la densité du produit fluide distribué depuis une source de fluide jusqu'à une destination. Le débitmètre massique de Coriolis compare la valeur de la densité mesurée à au moins une des deux valeurs limites de la densité supérieure et inférieure. Si la valeur de la densité mesurée dépasse une de ces valeurs de la densité supérieure et inférieure ou bien les deux, le débitmètre arrête automatiquement la pompe et ferme la soupape de surpression pour arrêter la distribution du produit fluide entre la source de fluide et la destination afin d'empêcher la mesure d'un écoulement de fluide polyphasique.
