Patent CA-2208231-C (CA)
Inventor: CASWELL DONALD
IPC: C08J3/205
Filed: 1996-12-03
Granted: 2005-02-15
Abstract: Disclosed is a polymer composition including nonaqueous additive system having dispersant-coated pigments physically dispersed in a liquid nonaqueous polymeric carrier which may be added directly to a melt flow of a polymeric host material. The additive system employed in the polymeric systems is is most preferably in the form of a particulate paste which can be added in metered amounts (dosed) to a melt flow of the polymeric host material prior to being spun into filaments. By providing a number of additive systems having a number of different additive attributes, and controllably dosing one or more into the melt flow of host polymeric material, shaped objects of the polymeric material (e. g., melt-spun filaments) having different additive attributes may be produced on a continuous basis without shutting down the shaping operation.

Title: Telephone exchange apparatus
Inventor: FUJITSUKA SHUJI
IPC: H04M1/57
Filed: 1997-12-19
Granted: 2004-08-17
Abstract: The emergency call such as Enhanced 911 call or the like is also originated through an exchange such as PBX (Private Branch Exchange). In this case, the identification information such as the extension number of the extension telephone terminal connected to the PBX should be transmitted to a network corresponding to the emergency call. For the extension telephone terminal, it is necessary to unhook or to capture an arbitrary line by the line key, before inputting the dial data "911". Independent of the capture of arbitrary line, the PBX searches a vacant line connected to the network corresponding to the emergency call, captures the vacant line, transmits the identification information such as the extension number, and switches over and connects the extension telephone terminal from the line captured by the terminal to the vacant line. The identification information such as the extension number is notified, not by the DTMF (Dual Tone Multi-frequency) signal expressing data corresponding to the number of dial key, but by using a MF (Multi-frequency) signal expressing more data.

Granted: 2002-12-10
Abstract: An activating mechanism (20) for activating an endoscopic ligator is disclosed. The activating mechanism (20) includes a mounting component (21) and an activating component (22) coupled thereto. The mounting component (21) inserts directly into the proximal opening of an operating channel of an endoscope and is dimensioned to fit within the operating channel to mount the mechanism (20) to the endoscope. The mounting component (21) includes a channel receiving an activation line of the ligating device which is threaded through the operating channel and the channel in the mounting component, and onto the activating component (22) of the activating mechanism (20). The activation line attaches to a spool (50) of the activating component (22). The activating component (22) further provides a drive pin (40) and a roller clutch (70) for setting the activating component (22) in an engaged or a disengaged position and a knob (60) for rotating the drive pin (40). When the drive pin (40) is engaged with the roller clutch (70), the knob (60) can only rotate in one direction. When the drive pin (40) is in the disengaged position from the roller clutch (70), the knob (60) can rotate in either direction.

Abstract: Apparatus for forming a cased glass stream having an inner core glass surrounded by an outer casing glass includes a first orifice for receiving core glass from a first source, and a second orifice vertically spaced beneath and aligned with the first orifice. A chamber surrounds the second orifice and communicates with the second orifice through a metering gap between the first and second orifices. Casing glass is delivered from a second source to one side of the chamber such that glass flows by gravity from both the first and second sources through the orifices to form the cased glass stream. In accordance with one aspect of the present invention, the metering gap is of non-uniform dimension around the chamber, providing greater resistance to glass flow through the metering gap on a side thereof adjacent to the side of the chamber that receives casing glass from the second source and less resistance to glass flow through the metering gap on the side thereof remote from the side of the chamber that receives the casing glass.

Abstract: Methods of fluid handling are disclosed. According to one method, a tip of a nozzle is moved below a surface of the fluid to be handled. A pump fluidly associated with the nozzle is energized to move fluid into the nozzle. A  pressure transducer fluidly associated with the nozzle is energized to monitor pressure within the nozzle. Pressure within the nozzle is substantially continuously monitored with the pressure transducer during operation of the pump. Based on the substantially continuously monitored pressure within the nozzle, it is determined whether movement of fluid into the nozzle is intended or unintended. Similar methods may be used to move fluid out to the nozzle.

Abstract: A communications network (200) may include a translation server (202) containing a NGPN-to-HLR mapping table. Translation servers (TS) may be configured in several ways. The server or several TSs may be on the network.  When a number of translation servers are used, a VLR (128) or other network entity receiving an NGPN determines which translation server contains the mapping for that NGPN. One way to do this is when a subscriber roams out of his "home" region, his NGPN is presented to the "foreign" service provider's TS. The foreing TS broadcasts a query to all other TSs in the network either simultaneously or in stages. Another way is that a VLR receiving a NGPN  performs a hash function of the NGPN. The hash function indentifies a translation server. The VLR may then query the translation server and obtain the NGPN-to-HLR mapping. Where a hash function is used, an extendable hash function to accomodate the addition of new TSs without changing the VLR  operating systems.

Title: Removal of carbon dioxide from gas streams
Inventor: BULOW MARTIN
IPC: B01D53/02
Filed: 1999-03-04
Granted: 2002-05-14
Abstract: Carbon dioxide is removed from gas streams comprised predominantly of gases that are less strongly adsorbed than is carbon dioxide by passing the gas stream through a bed of type X zeolite having a silicon to aluminum atomic ratio not greater than about 1.15 and at least 75% of the exchangeable cations of which are potassium ions, thereby adsorbing the carbon dioxide from the gas stream.    The process is particularly advantageous when applied to the removal of low levels of carbon dioxide from gas streams at temperatures of about 0 to 80°C.

Abstract: An apparatus for initiating a welding arc during a lift arc start. The apparatus includes a power circuit to provide welding power to a power output, a background circuit to provide background power to the power output to maintain the welding arc during low power welding processes, and a controller. The background circuit is enabled prior to drawing the welding arc, thus providing a background voltage to the power output of the welding device. The background voltage is monitored such that the controller can detect when the welder has touched the electrode to the workpiece. Upon detection of a short, the controller enables the power circuit to provide a flow of output current to the power output.
