Title: Discharge-pumped gas laser with baffle partition for controlled laser gas flow at preionizers
Inventor: ONO TAKUHIRO
IPC: H01S3/225
Filed: 1992-04-22
Granted: 1996-05-21
Abstract: A discharge-pumped gas laser has a pressure con-tainer filled with a laser gas under pressure and a pair of elongate main discharge electrodes.  The main discharge electrodes are disposed in the pressure container in con-fronting relationship to each other for producing an elec-tric discharge in the laser gas in a main discharge region defined therebetween to excite the laser gas for laser emission.  The laser gas is circulated to flow through the main discharge region in a direction perpendicular to the main discharge electrodes. The laser gas in the main dis-charge region is preionized by an UV preionizer disposed either upstream or downstream of the main discharge region with respect to the direction of flow of the laser beam.          The pressure container houses a baffle partition for con-trolling the laser gas to flow past one of the main dis-charge electrodes and the preionizer while blocking the laser gas from directly flowing to the other of the main discharge electrodes and the preionizer.

Title: Automated voice system for improving agent efficiency and improving service to parties on hold
Inventor: SZLAM ALEKSANDER
IPC: H04M3/523
Filed: 1992-05-14
Granted: 2000-10-31
Abstract: A method and an apparatus for improving agent efficiency by reducing non-productive time such as time on hold and time for wrap-up statements. After an agent has been connected to a call the agent may determine that automated handling of the call is appropriate. Depending upon the status of the call the agent may specify that the call has been essentially completed or that the agent is on hold. The agent may speak the name of the connected party and this will be recorded. Then the agent is disconnected from the call and a message playing device, which may also replay the spoken name, is activated. If the response from the connected party indicates that an agent's attention is again needed then the same or a different agent is connected to the call. In addition, a party on hold is provided an estimate of the time before an agent becomes available and/or the number of parties ahead in the holding queue.

Granted: 1997-09-23
Abstract: An optical fiber package of this invention applies a friction enhancing material to the smooth surface of a bobbin or mandrel onto which the optical fiber is wound. The friction enhancing material adheres the initial layer of fiber to the smooth surface of the bobbin, thereby eliminating the need for an independent base structure for establishing and maintaining a winding path for the fiber. Furthermore, the friction enhancing material prevents the lateral movement at initial layer of fiber relative to the bobbin. In accordance with the preset invention, the friction enhancing material is preferably a plastic material such as room temperature vulcanized (RTV) silicones and Styrene Butadiene Rubber (SBR) or the like. In addition, the optical fiber package of this invention may combine the use of both a friction enhancing material between the initial fiber layer and the bobbin, as well as an adhesive material coating applied along the length of the optical fiber. Accordingly, a stable package of elongated optical fiber strand material is established which may be used in situations or environments requiring rapid payout of the fiber without adversely effecting either the physical or the communicational properties of the fiber.

Granted: 2007-05-08
Abstract: A method and apparatus for forming complex shaped frame members from a tubular blank where the blank ie transferred from station to station and various tooling are performed on the blank at each station. For example, at a first station the blank is expanded into a tube having a varying cross-section throughout the length of the tube by applying pressure to the interior of the tube and compressive force to the opposed ends of the tube preferably simultaneously. At another station, the expanded tube is preformed by introducing a bend therein. The bend in the preformed tube is then increased at another station. While the expanded tube is being preformed and bent, the flow of material into the die cavity at those stations is controlled to reduce the amount of folding that may occur. The shape of the frame member is finished at another station by introducing a lateral bend and varying the cross-sectional configuration of the bent tube. Holes may then be pierced into the finished frame member at another station by pressurizing the interior of the frame member with,hydraulic fluid and striking the frame member with a piercing punch. Final stations crop the ends and flush the interior of the frame member before it is unloaded for further transport.

Granted: 2002-01-22
Abstract: An irrigator has an annular reservoir, open radially inwardly. A wall on the inside of the reservoir closes the open inner side and contains a bed of soil for growing plants. Wicks trickle moisture from the reservoir into the soil bed. In preferred versions of the irrigator, an impermeable plastic insert is designed to fit into the centre of a scrap vehicle tire as the reservoir. When inserted forcefully into one side of the tire, the tire is locked firmly onto the insert on one side to form a reservoir that has an opening between the opposite side of the tire and an upwardly tapered centre wall of the insert. When set into the ground, plants may be grown in the centre of the insert with moisture being fed into the centre growing zone from within the tire by wicks leading through appropriate slots in the insert wall.
