Title: Method and apparatus for generating oxygenated water
Inventor: HOUGH GARY S
IPC: C02F1/467
Filed: 1997-10-31
Abstract: A method and apparatus (10) for generating oxygenated water are shown and described. A plurality of electrolytic cells (16) are coupled to each other and to a source of water (12). A volume of water is drawn from the source (12), and forced through at least one of the electrolytic cells (16) at a user desired flow rate. If the demanded rate of flow at the outlet exceeds a threshold flow rate through the electrolytic cell (16), a valve (22) is opened and an additional volume of water flows through the second electrolytic cell (16) to the discharge (19), the rate of flow through each electrolytic cell (16) not exceeding the selected value. Additional cells (16) are added as needed. A varying demand of oxygenated water is therefore met, while ensuring that the dissolved oxygen content of the water at the outlet (19) does not fall below a selected value.

Abstract: A three-dimensional multi-chip module (MCM) is formed as a stack of twodimensional multi-chip modules comprising substrates (1) which have electrically signal paths connecting integrated circuit chips (3) and has vertical interconnections of the signal paths, provided by interconnection or via chips (9). The individual chips (3, 9) or other inner components (15) on a substrate (1) are in mechanical contact with a surface of an adjacent substrate and constitute the distance means maintaining the substrates spaced from each other. Thus heat developed in components can be conducted essentially perpendicularly to the substrates (1). Thermally conducting chips (15) can be used for improving the conducting of heat. Cooling means (19) are located only at the top and bottom surfaces of the stack. Channels (35) are formed between the chips and components which can be used for cooling and furthermore spaces (38) are formed at the edges of the substrates in which electrical connectors (37) can be inserted for coupling the stack to a similar stack. The components (1, 3, 9, 15) of the stack is maintained in a detachable manner in electrical and mechanical contact with each other by applying a compressive force and by using elastic connecting and guiding means (21, 25, 27). In particular bumps (21) can be arranged cooperating with edge surfaces of components to guide components to correct positions.

Abstract: A Raman fiber laser comprises a laser as a pumping source whose light illuminates a fiber waveguide length having an oxide matrix which includes phosphorus oxide. The apparatus further comprises two pairs of fiber Bragg gratings which form distributed mirrors for a first and a second Stokes components resulting from the presence of phosphorus oxide, and long-period gratings for extracting light of first Stokes components resulting from the presence of silicon oxide and/or germanium oxide and generated by light of the pump laser and the first Stokes component resulting from the presence of phosphorus oxide. The long-period gratings provide an additional optical loss in the Stokes components to prevent resonance conversion of the pump light and the light of the first Stokes component resulting from the presence of phosphorus oxide into these Stokes components, thereby improving the efficiency of resonance conversion of the pump light into the second Stokes component resulting from the presence of phosphorus oxide.

Title: De-entrainment tray and method of operation
Inventor: ROSS MARK SHELDON
IPC: B01D19/00
Filed: 1998-02-17
Abstract: De-entrainment devices {28) are provided for separating an entrained liquid from a vapor stream exiting a flash zone (14) in a separation column (10). A de-entrainment device includes a de-entrainment tray (24) that has a tray deck (26) and a plurality of risers extending vertically up from the tray deck. The risers (32) are provided with a rotational vane (60) for imparting rotational movement to the fluid stream including the vapor stream and the entrained liquid, entering the riser. The rotational movement imparted to the fluid stream causes the liquid to separate from the vapor stream and to flow upward along riser walls (32). The de-entrained liquid is then transported from the above separation tray back into the flash zone by way of a liquid downcomer (40). The vapor stream separates from the liquid within the riser and flows out of the riser upward through the column. A riser hat (50) is used to prevent a wash liquid from entering the riser and the liquid downcomer.

Abstract: A cylindrical shaft has a plurality of radially disposed slots extending longitudinally thereof and opening at the outer surface of the shaft. A radially movable mechanism is disposed within each of the slots. Each mechanism is moved outwardly by an expandable tube. One of the slots opens at a side face of the shaft to provide a side opening through which a track can be inserted into and removed from the slot. Springs bias the track radially inwardly. The track includes an open end through which a support can be inserted into and removed from the track. A two piece retainer retains the track and support in operative position. A plurality of core stops are carried by the support and can be either adjustable longitudinally of the support or fixed to the support. The core stops engage side edges of tubular supports disposed around the shaft for spacing the tubular supports for a winding operation. One support with a particular spacing of core stops can be replaced by another support with a different spacing of core stops very quickly to minimize downtime of the shaft. In a modification, the support is of less length than the associated slot, and an adjusting lug is movably supported at opposite ends of the support. Screws are provided for locking the adjusting lugs and the support in adjusted position.

Patent CA-2296939-A1 (CA)
Inventor: BARTELS JAMES I
IPC: G01R31/28
Filed: 2000-01-21
Abstract: Control potentiometers are monitored by using a computer processor and a monitor interface circuit connected between the potentiometer and the processor. The potentiometer, its terminals and its wiper are monitored for faults. In addition the monitor interface circuit itself is tested so that a fault in the potentiometer or a fault in the monitor interface circuit is detected to prevent the control potentiometer and monitor interface circuit from producing an incorrect control signal. The monitoring is accomplished by measuring changes in the full potentiometer resistance from a predetermined value. The changes are compared against boundary limits to detect whether a change is inside or outside the boundary limits. A  fault in the control potentiometer is indicated when a change is outside the boundary limits.  The monitoring also monitors wiper resistance of the potentiometer. The wiper resistance of the control potentiometer is measured, and the wiper resistance is compared against a fault threshold to detect if the wiper resistance has passed the fault threshold. A fault in the wiper of the control potentiometer is indicated when the wiper resistance has passed the threshold. The testing of the monitor interface circuit is accomplished by measuring idle signals applied to the full potentiometer and to the wiper when the monitor interface circuit is an idle state. The idle signals are compared against an expected signal to detect if the idle signals are within a predetermined tolerance range of the expected signal. A fault in the monitor interface circuit is indicated if the idle signals are outside the predetermined tolerance range.
