Patent CA-2359284-A1 (CA)
Inventor: PETTICREW RICHARD
IPC: A61K6/06
Filed: 2001-10-18
Abstract: The present invention is concerned with a process for the formation of dental restorations from glass-ceramic materials, and the resulting dental restorations. In this invention, a dental restoration is prepared by placing a glass-ceramic material in a heat-pressure deformable crucible. Heat is then applied to the crucible in order to bring the glass-ceramic material to working range at temperatures above its liquidus temperature. The crucible in which the glass-ceramic material is placed has heat-pressure deformation properties which are matched to the working temperature of the glass-ceramic material being heated. The heat deformation properties of the crucible must be such that when the glass-ceramic material in the crucible is in the working range, the crucible is heat-pressure deformable without rupturing. Once the glass-ceramic material is heated to its working temperature, the crucible is brought into contact with a mold having a preformed cavity therein, the cavity being in the shape of the desired dental restoration. As the distance between the heated glass-ceramic material and the mold is decreased, the crucible is deformed to form a seal with the mold, thereby facilitating the injection of the molten glass-ceramic material into the mold cavity. An interactive seal between the crucible and the mold may be provided for. The composite process may be carried out in a vacuum. The resulting dental restoration has superior optical esthetic and strength properties. The invention further includes the heat-pressure deformable crucible. The invention includes dental restorations which are formed from particular lithium-disilicate glass-ceramics. In addition to forming dental restorations by the process of this invention, the dental restorations may be milled.

Inventor: CHAN ERIC L
IPC: H04L12/56
Filed: 2000-03-14
Abstract: A method and apparatus for the robust implementation and protection of Asynchronous Transfer Mode, ATM, traffic over a Synchronous Optical Network, SONET, Unidirectional Path Switched Ring, UPSR (100). The traditional SONET  bridging function is eliminated for the ATM traffic in favor of a selector function. The selector function occurs at the ingress of the ATM traffic to the UPSR and directs the ATM traffic to its destination via a virtual path over the UPSR. The ATM traffic is protected from both SONET failures and ATM  failures by an Intra-Ring Communication IRC protocol (300). The IRC protocol governs failure detection and the notification of the SONET nodes on the UPSR  of the failure and any protection switch that may be necessary (750, 800).

Abstract: The toothbrush of the present invention comprises an elongated handle having a head attached to one end. The head has a bristle-bearing face having longitudinal perimeter portions adjacent longitudinal edges and at least two perimetric, elastomeric massaging elements alternately arranged with groups of bristle tufts along each of the longitudinal perimeter portions. The brush can comprise further massaging elements which are not located along the longitudinal perimeter portions though the use of such additional elements is preferably minimised. The perimetric massaging elements have rotational symmetry through an angle of 120° or less, preferably being circular. The cross-sectional area proportion of elastomeric massaging elements to bristles on the brush head is less than 25 %. Alternately there are four or fewer elastomeric massaging elements which are not perimetric massaging elements. A brush with both bristles and gum massaging elements arranged as set out above provides both cleaning and gum massaging benefits without creating an undesirable aesthetic impression derived from the use of rubber-like materials in the part of the brush head traditionally comprising only bristles.

Abstract: A fibre optic sensor system provides sufficient thermal information to determine the mass flow rates of produced fluids within a well bore, us-ing an optical fibre placed within or adjacent to the well bore without interference with production or prej-udicing the integrity of the well. Mass flow rates of fluid in a conduit (20) located in a heat sink differing in temperature from the fluid are determined by obtain-ing a distributed temperature profile (32) of fluid flow-ing along a length of conduit (15) by means of optical data obtained from a length of optical fibre in thermal contact therewith, obtaining a profile of the heat sink temperature external to the conduit, and deriving mass flow rates of fluids in the conduit from the said pro-files and from measured thermal transfer parameters.  Corresponding apparatus comprises a length of opti-cal fibre in thermal contact with the fluid, means (22) for obtaining a distributed temperature profile of fluid flowing along a length of conduit by means of opti-cal data obtained from said length of optical fibre, and means for deriving mass flow rates of fluids in the con-duit from the said profiles and from measured thermal transfer parameters.

The vibration absorbing member has substantially cylindrical shaped first and second portions provided along a longitudinal axis of the shaft member. An engagement recess is formed between the first and second portions of the vibration absorbing member to engage a through-hole in the frame. The cylindrical second portion is larger in diameter than the cylindrical first portion. A set screw with a flanged-shaped head and a threaded shaft portion engages the threaded opening of the shaft member. The flanged-shaped head engages the vibration absorbing member's second portion to secure the vibration absorbing member to the shaft member. An elastic member is formed on an outer side of the first cylindrically shaped portion and extends between the frame and the base member to bias the frame away from the base member.
