Title: Guide wire dispenser apparatus and method
Inventor: PECOR ROBERT
IPC: A61M25/01
Filed: 1997-05-15
Granted: 2000-02-03
Abstract: A storage and dispensing apparatus for a springy guide wire used in medical procedures includes a coiled tubular portion defined by elongate tubing with a bore for receiving the guide wire. A ring section includes a tangential portion of the tubing defining an open end from which the guide wire may be dispensed. Adjacent to the tangential portion, the tubing defines a pair of spaced apart openings from which the guide wire respectively exits and reenters the tubing. Intermediate the pair of openings the tubing defines a curved external surface across which the guide wire runs externally of the tubing and is manually accessible for advancing and retracting movements impelled by a user's thumb, for example. The guide wire defines a pair of gentle S-shaped bends adjacent to the ends of the externally-exposed curved section, which bends cause the guide wire to engage sufficiently with the storage and dispensing apparatus to resist self-ejection.

IPC: F16T1/20
Filed: 1999-09-03
Granted: 2002-07-04
Abstract: An automatic drain valve for discharging accumulations of fluids and foreign materials from a fluid handling system. The drain valve (10) comprises a reservoir (14) defining a reservoir volume (15) and a thru-port (28), in fluid communication with the reservoir volume (15), that defines an inlet (30) and terminates in a drainage valve (82) for flowthrough communications with a fluid handling system. An actuating mechanism selectively actuates a valve operator. In the preferred embodiment, a pilot valve (41) is mounted in the reservoir (14) for selectively communicating pressurized air to a valve operator (57), such that the valve operator selectively opens and closes the drainage valve (82) communicating with the outlet (88) of the reservoir (14) for selectively draining the reservoir. The pilot valve (41) includes a sensor tube (42) which defines a valve seat (44) and includes a magnetized valve plug (46) for selectively engaging the valve seat (44), the valve plug (46) having a selected magnetic polarity. A level sensing float (52) disposed within the reservoir (15) carries an annular magnet (56) normally having a polarity opposing that of the valve plug (46) such that the annular magnet (56) acts upon the valve plug (46) selectively opening and closing the pilot valve (81) as the float (52) rises and falls from a raised position to a lower position with the level of liquid within the reservoir (14).

Title: Method of training a PCM modem
Inventor: TOWNSHEND BRENT
IPC: H04B3/10
Filed: 1998-02-19
Granted: 2001-03-01
Abstract: A new data communication system is described which enables data transmission over existing telephone lines at rates higher than possible with existing methods, including conventional modems. By using a novel asymmetric configuration of the two communication endpoints, the currcntly-accepted maximum theoretical limits on the data rate are no longer applicable. One endpoint is connected directly to a digital telephone network, whereas the other endpoint uses a conventional telephone connection. This reduces the transmission problem to compensation for a single telephone line interface and a single analog local loop. Means of providing this compensation and the required clock synchronization were also created, enabling a practical implementation of the system. The new system can achieve rates up to 64,000 bits-per-second and has broad utility in several active areas including wideband audio transmission, video transmission, networking, facsimile transmission, and remote computer access.

Title: Method for making a preform doped with a metal oxide
Inventor: POWERS DALE ROBERT
IPC: C03B37/018
Filed: 1990-11-12
Granted: 1994-03-17
Abstract: A method for making preforms by vapour phase soot deposition processes is disclosed, whereby an oxidizing atmosphere is used during at least part of the deposition process; e.g. during the deposition of the centre portion of the preform. The oxidizing atmosphere results from supplying oxygen, available to react with the fuel, in an amount which is stoichiometrically in excess of that required to fully oxidize the fuel. This results in enhanced dopant capture, reduced axial inhomogeneities (e.g. of dopant) in the consolidated preform and finished fibre, and an overall stabilization of the deposition process. A method for selecting burner flow rates which optimize the deposition process is also disclosed. The reaction deposition burner used to carry out the process has:- a first passageway (13) and second passageway (15), both of which carry at least oxygen but no fuel; a third passageway (17) to carry at least fuel and oxygen; and optionally a fourth passageway (19) to carry at least oxygen but no fuel, for shaping the flame.
