Abstract: A disposable dome lid is provided for use with a drinking cup such beverage cups used for the sale of hot and cold beverages. The top surface of a dome lid is elevated above the top surface of the beverage cup rim, when in place. The dome lid is configured so as to make a plug fit onto the beverage cup by the beverage cup rim extending into a downwardly facing recess formed for that purpose. A side surface depends downwardly from a substantially planar top surface of the lid, and is inset from the cup rim engaging recess. A portion of the side surface is displaced outwardly towards the outer periphery of the dome lid, and thus provides a surface for engaging the lower lip of the mouth of the user. A tear-back flap is defined by fault lines stamped into the top surface and a "U"-shaped hinge formed in the top surface. When the tear-back flap is folded back, a locking stub extends downwardly into a locking recess formed in the top surface of the lid, and a drink- through opening is thereby created in the top of the dome lid near the outer periphery thereof, for easy drinking access to the beverage in the cup.

Abstract: The invention relates to a method for the manufacture of surface-structured bristle material from plastic by extruding a monofilament. Before or during extrusion a granular material is admixed with a thermally melted first plas-tics material forming the main component of the monofilament. The granular material comprises a second plastics material, which has a higher thermal strength than the first plastics material. The particle size of the granular material is such that the monofilament, during a subsequent stretching, is subject to a greater transverse contraction in cross-sections where there is little or no granular material than in cross-sections containing granular material. The invention also relates to a bristle with a surface structure from a first plastics material forming the main component and in which is embedded in a substantially completely covered manner a granular material of a second plastics material, the granular material forming a structuring on the bristle surface. The invention also relates to a brush, particularly a toothbrush or interdental cleaner, with a plurality of bristles, optionally combined into bundles and in which at least certain bristles have the afore-mentioned structure.

Title: Method and devices for bridging data and telephone networks
Inventor: BELZILE PIERRE
IPC: H04Q3/66
Filed: 1998-08-31
Granted: 2005-02-22
Abstract: A data network to telephone network gateway (16) and an end-user computing device and method used by these devices are disclosed (26). The gateway (16) is in communication with both a data network (10) and a telephone network (12). The computing device (26) is in communication with the data network (10). The gateway (16) is adapted to receive an indicator of a telephone call and dispatch a notification of the call destined for the computing device (26). As well, the gateway (16) causes the call to be bridged from the telephone network to the computing device over the data network (10), enabling a user at the computing device (26) to communicate with the call using the computing device (26). After the call is bridged, and in response to a specified condition, the gateway (16) causes the call to be forwarded to a telephone line (34) interconnected with the telephone network. The specified condition may include an end-user input, or a detection by the gateway or the computing device that the quality of the bridged call has fallen below an acceptable standard, arising typically from congestion or delays on the data network (10). This allows the end-user to maintain a high quality call connection.

Title: Charging systems for services in communications
Inventor: SMYTH PETER PAUL
IPC: H04M15/00
Filed: 1997-04-01
Granted: 2002-10-22
Abstract: In a charging system for cellular communications, real-time prices for new connections are offered to the customer. The real-time prices take into account both prevailing and historic traffic patterns, together with the probability that the customer will move from their current cell into a neighbouring cell. Cells of the network are monitored in clusters. If a customer is located in one particular cell, the price offered to that customer will take into account the probability of handover to a neighbouring cell during the connection, and may also take into account the probability of incoming traffic from neighbouring cells during the connection. To enable this predictive pricing, the system stores, and may also update, historic data.

Title: Modified acrylic urethane prepolymer concentrate and polyester resins containing same
Inventor: SMITH STUART B
IPC: C08F283/01
Filed: 1997-04-10
Granted: 2003-07-08
Abstract: A modified acrylic urethane prepolymer composition and an unsaturated polyester resin composition to which the prepolymer has been added. The prepolymer composition includes an acrylic urethane prepolymer prepared by the reaction of diisocyanate, like MDI, with a hydroxyl-containing acrylate monomer, such as a pentaerythritol triacrylate, which prepolymer composition may contain a styrene monomer and an inhibitor, such as benzoquinone, to retard the reaction of the prepolymer and styrene monomer prior to the addition of the prepolymer composition into the polyester resin composition.  The employment of the modified urethane prepolymer composition provides for the reduction in the amount of styrene monomer used in the unsaturated resin composition and also provides for improved chemical and physical properties of the cured, unsaturated resin composition, such as a reduction in glass roll-out when the resin composition is employed with fiberglass.
