Abstract: A telephone system provides dynamic inbound/outbound call management for a telemarketing campaign to automatically initiate outbound telephone calls for outbound agents, with outbound agents redesignated as inbound agents to answer inbound calls as needed according to at least one threshold of number or duration of waiting calls or number or duration of waiting inbound agents. Each agent's work area (35) includes a telephone station (40) having a display (30) and an input device (32). The telephone stations (40) are coupled to a server (20) via a network, and the telephone system includes appointment and calendar functions with pop-up menus.  The server (20) is also coupled to an automatic dialer (50) and to a private branch exchange (60). When the server (20) assigns an outbound call to an outbound agent, the server sends information about the party called to the outbound agent's telephone station for display simultaneous with connecting the called party to the outbound agent.  The telephone system allows each agent to control all telephone functions through the telephone station using the display (30) and input device (32). Each agent may dial and control additional calls using the input device (32), including central office calls, intercom calls and paging. As each outbound call is initiated or completed, system parameters are adjusted to maintain a predetermined minimum number of busy outbound agents. The adjustments also maintain the percentage of unattended outbound calls for which no outbound agent is available.

Abstract: A float valve 10 includes a valve body 12 for sealing engagement with a float sub 20 having threads for threaded engagement with an oilfield tubular. A  valve element 40 includes a stem 50, 70 and a valve cone 52, 80 secured thereto. The valve cone is configured for sealing engagement with a seat 58 on the valve body. An elastomeric seal 48 may also be provided for sealing engagement with the valve body. The stem 50, 70 and the cone 52,80 are preferably interconnected by a shrink-fit operation, wherein the cone is heated so that a cylindrical recess within the cone expands, while at least a front end 52, 72 of the stem 50, 70 is cooled so that its diameter is reduced. The shrink-fit operation forms a surprisingly reliable interconnection of a float valve stem with a cone, and substantially increases the life of the downhole float valve.

Title: Syringe, its sealing structure and sealing method and sliding valve for syringe
Inventor: HIGASHIKAWA TETSURO
IPC: E04F13/08
Filed: 1995-12-27
Granted: 2000-03-21
Abstract: A waterproof film (11) for covering fitting portions is closely formed on surfaces of a cap (6), barrel (3) and a cylinder body (2) to serve as a sealing construction for a syringe. The film is made of a synthetic resin having a higher fusing point than a temperature of steam which passes at the time of after-sterilization. A substantially wave-shaped inclined lip (24) is continuously formed on and projected from an outer periphery of a short-column shaped elastic body (22) to serve as slide valves for a syringe. An annular lip (23) is formed on an end of the body. A notch (34) for introduction of chemicals is formed on the inclined lip. The inclined lip is constructed such that substantially diverging lips are formed in pairs or in multi-stage or in axial ridges or intersecting one another in a corrugated manner. These slide valves are inserted and mounted without inclination to eliminate accumulation of air inside. In the syringe, an enlarged diameter portion (87) having a larger diameter than that of a cylinder is formed integrally on a tip end side of the cylinder such that it has a larger inner diameter than outer diameters of the slide valves to permit a chemical to be discharged through a gap around the outer periphery. A support projection (94) for the slide valves is formed at a bottom wall of the enlarged diameter portion to provide a bottom gap. A  slide valve (90) comprises a body (101) having a smaller diameter than an inner diameter of the enlarged diameter portion, and a support member (102) having a lower elastic modulus than that of the body and a plurality of circumferentially equidistantly distributed support projections which project diametrically from inside of the body and contact with an inner surface of the enlarged diameter portion. The cylinder is of unitary-type, so that passing steam, bacteria and the like are prevented from entering the syringe.

Abstract: A ground fault protection circuit for plural loads connected across a power source with plural branches which can be used where the loads are unbalanced. Each branch includes a ground fault circuit interrupter device that has a common line for the electronics of the GFCI separate from the neutral line from the power source to the load where the common lines for the electronics for the ground circuit interrupter devices in each branch are connected to a common point. The ground fault protection circuit employs plural ground fault circuit interrupter devices and eliminates nuisance tripping. The common line for the electronics for a GFCI is routed through the core of the current sensing transformer of the GFCI. The separate neutral line for the electronics, connecting the common lines for the electronics for plural GFCI devices and routing the common lines for the GFCI electronics through the core of the transformer of each GFCI, eliminate improper GFCI operation due to unbalanced loading. The ground fault protection circuit may be used for a three phase power source.

Title: Process for preparing a paper web
Inventor: NYGARD STINA
IPC: D21C9/16
Filed: 1998-09-16
Granted: 2006-06-20
Abstract: The present invention concerns a process for preparing a paper web. According to the process a pulp is formed from a fibrous raw material, a web is formed from the pulp and it is dried on a paper machine. According to the invention the pulp is formed from a mechanical pulp produced from a peroxide bleached mechanical wood raw material of the genus Populus, the pH of proportioning of the mechanical pulp being set at 6.8 to 7.2 and the machine pH at 7.1 to 7.5 and the conductivity of the pulp being set at 1000 to 1500 µS/cm. By using a relatively low pH value and a narrow pH range it is possible to diminish the sensitivity to disturbances of the paper making process. According to the present invention a mechanical aspen pulp can be combined with chemical pulp for preparing base paper of fine paper, whereby the mechanical pulp gives a high conductivity on the machine which improves the stability of the wet end and enhances water removal.

Abstract: A connector for coaxial cables having an inner conductor (14) and an outer conductor (10) separated by a dielectric (16) includes a front body (4) to attach a coaxial cable in the connector and a rear body (8) adapted for connection to the front body (4), and a device for holding the cable in the connector in a manner that permits reproducible deformation of the outer conductor (10) during the connecting operation. The device for holding the cable in position is comprised of a ferrule (1) for holding the coaxial cable, and a bushing (2) that cooperates with the ferrule (1) to permit axial movement of the coaxial cable over a determined distance (L) in the connector during the connecting operation. The surfaces of ferrule (1) and bushing (2) cooperate to produce reproducible compression and/or deformation of the outer conductor (10) between said ferrule (1) and said bushing (2) during said connecting operation. The connector enables the coaxial cable to be deformed during the connection operation in an automatically reproducible manner without requiring precise measurements or special tools. The impedence fault value produced by the deformation of the outer conductor can be predetermined and is automatically reproduced during each connection operation.
