Title: Hydraulic valve
Inventor: DE PIERI TIMOTHY
IPC: F16K1/12
Filed: 1994-09-15
Granted: 2005-05-10
Abstract: The present invention discloses a valve which utilises an unbalance of flow induced pressure forces to keep the valve open or closed. The valve has an interior cavity (15) into which an opposite and aligned inlet (12) and outlet (13) open. A bulbous body (16) is located within the cavity and is reciprocally mounted on a spindle (17) which passes through the outlet. Movement of the body increases the flow area at one end of the body and decreases the flow area at the other end of the body.  In accordance with Bernoulli's theory this changes the pressures acting on the body (16) giving rise to a net force on the body. A cistern inlet valve (111, 211) and cistern (19) are also disclosed.

Title: Method in the drying of a paper web as well as dryer sections of a paper machine
Inventor: KERTTULA REIMA
IPC: D21F5/16
Filed: 1994-11-29
Granted: 2000-08-08
Abstract: The invention concerns a method and a device in the drying of a paper web (W), wherein, after the press section (20) of the paper machine, the paper web (W) is dried in a number of successive groups (R1...R N;R S) with single-wire draw, in which groups the contact-dry-ing cylinders (10) are placed in the upper row and the reversing suction cylinders (11) or the equivalent suction rolls in the lower row or in equivalent diagonal or vertical rows. From the side of its lower face, across the entire length of the dryer section, the paper web (W) is dried by means of contact-drying cylinders (10). The paper web (W) is passed as a closed draw from one group (R1...R N; R S) with single-wire draw to the next group, and the paper web (W) is guided, while it is placed on the drying wire (15) at the side of the outside curve, by means of the reversing suction cylinders (11) with a curve radius D2/2, which is chosen in the range of D2/2 = 250...1000 mm. The paper web (W) is kept in constant contact with the drying wire (15), as it is placed at the side of the outside curve, against the effect of centrifugal forces by means of a difference in pressure, which difference in pressure is preferably extended over the entire inner circumference of said reversing suction cylinders (11). In addition to the above, or as an alternative, the paper web (W) is dried from the side of its upper face on a draw (W1) or draws of the paper web (W) that is/are free from the wire (15) and/or a flow of drying air is applied to the upper face of the paper web (W) through the drying wire (15) and/or on said draws (W1) of the paper web (W) that are free from the wire (15).

Granted: 1999-01-19
Abstract: A ground fault interrupter (gfi) wiring device is disclosed in the form of a duplex wall receptacle.   A pair of electrically conducting members in the form of small buss bars each carry two, spaced contacts.   The buss bars are moveable to bring their respective contacts into and out of engagement with fixed contacts on the hot and neutral terminals on the line and load sides of the receptacle.   The buss bars are biased toward movement to the circuit-breaking position by respective coil springs extending through openings in a separator member dividing the interior of the receptacle housing into front and rear compartments.  One end of each spring rests upon a respective buss bar and the other end is contacted by an integral portion of the front housing section, the springs being compressed to apply a biasing force to the buss bars only upon placing the front housing section in mating engagement with the rear section.  The support means for the buss bars permits pivotal movement of the latter to ensure good engagement with the fixed contacts.  The line terminals and a separator element within the device housing permits mounting of the terminals with the female contact for receiving a plug blade and the fixed contact in upper and lower compartments defined by the separator.

Abstract: A highly efficient partial oxidation process with the production of power comprising the steps of producing fuel gas by the partial oxidation of hydrocarbonaceous fuel, cooling said fuel gas at high pressure by quenching in water to produce quenched fuel gas and by indirect heat exchange with BFW to maximize the production of IP and MP steam, cleaning said fuel gas, preheating scrubbing water comprising process condensate and make-up water by direct contact and direct heat exchange with clean fuel gas and using said preheated scrubbing water in the cleaning of said fuel gas, reducing the pressure of said cooled fuel gas stream prior to heating water for fuel gas saturation, cooling the process fuel gas stream in stages and condensing water for use as said scrubbing water, purifying the process fuel gas and saturating it with water, and burning said purified and saturated fuel gas in the combustor of a power-producing gas turbine along with saturated nitrogen to produce exhaust gas with a reduced NOx. In one embodiment, the hot exhaust gas from the gas turbine is passed through an HRSG to superheat the process steam. The superheated process steam is then used as part of the working fluid in an expansion turbine for the production of power. Steam condensate may be converted into high pressure (HP) steam and superheated in the HRSG. The superheated HP steam is then passed through an HP expansion turbine as the working fluid. The power generation steam cycle is optimized to assist in maximizing the process steam which can be used most efficiently in the cycle.
