Patent CA-2280909-C (CA)
Title: Gels de silice hydrophobes a vieillissement neutre presentant une zone superficielle limitee
Inventor: BURNS GARY T
IPC: C09C1/30
Filed: 1998-02-18
Granted: 2007-11-13
Abstract: L'invention concerne des gels de silice hydrophobes ayant subi un vieillissement neutre et présentant une zone superficielle limitée, ainsi qu'un procédé servant à préparer ces gels. Ce procédé comprend trois étapes: la première étape consiste à mettre en contact un mélange composé d'un hydrosol de silice et de silice colloïdale avec un acide minéral fort à un pH inférieur à 1, afin d'obtenir un hydrogel de silice dans lequel est incorporée de la silice colloïdale. La deuxième étape consiste à effectuer le vieillissement de l'hydrogel de silice à un pH situé dans une plage de 3,5 à 8. La troisième étape consiste à mettre en contact l'hydrogel de silice avec un composé d'organosilicium en présence d'une quantité catalytique d'un acide fort, ce qui a pour effet de rendre hydrophobe l'hydrogel de silice et permet d'obtenir un hydrogel de silice hydrophobe dont la zone superficielle est située dans une plage de 100 m<2>/g à 450 m<2>/g à l'état sec. Un procédé préféré consiste à mettre de nouveau en contact l'hydrogel de silice hydrophobe avec une quantité suffisante d'un solvant organique non miscible dans l'eau, de manière à convertir l'hydrogel de silice hydrophobe en un organogel de silice hydrophobe.

Abstract: A threaded actuator is disclosed for positioning a core in a molding apparatus. The threaded actuator includes a hydraulic cylinder unit having a piston rod connected to the core for positioning thereof. The core is subjected to intense force during the molding process and this force is transmitted onto the piston rod and hydraulic cylinder unit and its support. The hydraulic cylinder has a threaded nose which is secured within a threaded opening in a support. A rotatable threaded connecting member is threaded between the threaded nose and the threaded opening of the support structure. The outer and inner threaded connections of the rotatable threaded connecting member are of different thread configurations to form a differential thread assembly. The configurations may differ either in pitch and/or in the handedness of the threads. The differential threaded assembly provides for relative positioning of the hydraulic cylinder unit and core relative to the mold. A preload system includes a wall on the cylinder and a wall on the rod for preloading of the locked rod and the supporting components. The hydraulic cylinder and the piston rod are formed with stop wall members which provide for controlled extension of the piston rod for preloading of the piston rod and the supporting structure. A locking unit provides for locking of the rod in an extended position.

Patent CA-2324468-C (CA)
Inventor: SCHOFIELD BRUCE A
IPC: H04B10/2581
Filed: 1999-05-21
Granted: 2004-10-12
Abstract: A method of improving modal bandwidth in computer networks using multimode optical fiber and single mode sources is disclosed in which the optical signal from a center of the optical fiber is prevented from reaching the detector. This is accomplished according to a number of different techniques including the use of opaque spots on the fiber media/fiber couplers or the use of dark-cored fiber couplers. These configurations prevent pulse splitting that occurs in single mode source/multimode fiber systems by preventing light from the multimode fiber's center from interfering with the detector. When this is achieved, the detector is insulated from the effects of pulse splitting, supporting increased data rates by increasing the modal bandwidth.
