Inventor: TAYLOR H D
IPC: F15B13/02
Filed: 1980-03-25
Abstract: A hydraulic pressure relief circuit includes a main valve (14), a bleed flow orifice (18) to provide stability to the main valve, a pilot valve (20) having a differential area piston (30,32) and a damping orifice (46) in conjunction with an accumulator (44). System pressure is limited by opening the main valve and allowing fluid flow from the system back to tank. The main valve is controlled as a bleed flow servo wherein the pilot valve (20) meters the bleed flow from the bleed flow orifice (18) to tank, thereby controlling the opening of the main valve. Fluid flow through the damping orifice (46) in conjunction with the accumulator (44) acts on area (A1) of the pilot valve to provide damping forces acting on the pilot valve with both rising and falling system pressures, thereby limiting the maximum rate of pressure increase in the circuit (10). <IMAGE>

Abstract: A welding wire gun operable in the high temperature environment of a high current density welding system. The welding gun includes a tubular member through which welding wire and shielding gas are adapted to pass. A gas diffuser member is mounted upon one end of the tubular member and, in turn, supports a welding tip therein such that the end of the welding tip projects beyond the diffuser in the direction of the joint to be welded. Additionally, the welding gun is constructed to provide for flowing of a coolant material around the tubular member proximate the diffuser member for maintaining the welding tip below its melting or distortion temperature. A tubular nozzle member is supported at one end from the diffuser member and extends beyond both the diffuser member and the welding tip in such a way as to define an annular shielding gas chamber about the diffuser and welding tip. Gas passages formed through the diffuser communicate with the annular gas chamber and are angularly oriented with the central axis of the diffuser and welding tip so as to maximize the velocity and minimize turbulence of the gas flow through the gun to thereby maintain a high energy shielding gas envelope around the welding wire and weld puddle.

Abstract: (57) The invention concerns a method for delivering pulp onto the wire of a paper machine into a sheet which in the later stages in converted into finished paper. The thick pulp from the pulping process is suspended with the white water recirculated in the paper machine into a suspension, which is delivered onto the wire into a homogeneous sheet and from which the water drained through the wire is recirculated to the suspension process. The closed circulation allows the enrichment of constituents such as hemicellulose dissolved or dispersed from the stock being prepared that lower water drainage and degrade the retention of fibers. According to the invention, enzymes are added to the lean white water of low consistency that are capable of disintegrating said deleterious constituents. The enzyme can be added to the short circulation of lean white water taking place from the sheet forming on the wire to the suspension process of the pulp, or alternatively, to the long circulation of the white water to other locations of use in the paper machine. The invention is particularly applicable to papermaking based on mechanical pulp such as TMP in which the amount of hemicellulose dissolving in the white water is highest.
