Abstract: GOVERNING SYSTEM FOR USE IN              SLIDING-PRESSURE TYPE TURBINE                       POWER PLANT     ABSTRACT OF THE DISCLOSURE         A governing system for use in a sliding-pressure type turbine power plant, in which a target level for a main steam pressure is automatically set in response to a load demand, while two or more regulating valves are controlled according to a valve-positioning signal so as to eliminate a deviation of an actual load from a load demand, whereupon a target level for the main steam pressure is corrected, based on the diviation of the actual opening from the target opening of each regulating valve, whereby the main pressure generated in a boiler is regulated to a corrected target level.  This governing system includes a valve driving mechanism functioning such that all regulating valves be opened at a time in a range up to a given opening, and thereafter the regulating valves be opened one after another, commensurate to the magnitude of a control signal, after entering a range beyond the aforenoted given opening.

Abstract: FIELD FAN FILTER   ABSTRACT         Apparatus for fan filtering seismic data in the field comprising inputs for receiving signals from each seismometer in a group, summing amplifiers for summing the received signals by pairs, charge-coupled device delay lines for providing two different delays to each of the summed pairs, amplifiers for taking the difference of each of the two delayed signals from each summed pair, and means for weighting and summing the outputs of all pairs.  The time delays of each of the charge-coupled device delay lines are proportional to and contolled by a single clock, which can be time-variable.  The clock may be held at a single frequency during the taking of a given record, but in the preferred embodiment the clock is varied during recording to provide a narrower pass band of apparent velocities for deeper reflections than for the shallow reflections.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved flare system in which steam is injected into the column of gas to be burned, from circumferential nozzles at at least two spaced levels, above the tip of the flare stack. A circular manifold surrounds the stack just below the tip and an even number of small diameter riser pipes are attached to the manifold, spaced equally circumferentially. The riser pipes have nozzles all of which are directed radially inwardly and upwardly at a selected angle. Half of the nozzles are spaced at a first selected distance above the tip of the flare stack, and the other half are positioned at a greater selected elevation above the tip of the flare stack. Alternate risers have different elevations of the nozzles. By this means, a minimum diameter of the cross-section of the gas flow is occluded by the steam flow.

Abstract: ABSTRACT The present invention relates to a device to dampen and compensate automatically the pulling force which is exerted on a strip undergoing a high acceleration during its entrainment.  The problem which exists here is that when a strip is unwound from a stopped reel, the pulling force exerted on the strip subjects the material to excessive tensile stresses, which may exceed the limit value of resistance of the material, thereby causing tears or breaks.  The device of this invention dampens and compensates the com-bined effect of the pulling and resisting forces, so as to reduce the ten-sions which are produced.  The device comprises idler rollers sliding on a guide which deflect the strip, and a dampening device which is applied to the deflecting action of the roller, and which is adjustable so as to exert on the strip a constant counter-push, which is always lower than that which would cause a tear in the strip.  The deflecting device moves progressively backwards, in relation to the push exerted on it by the accelerated strip.  The device is applied to a portion of the strip between the starting point of the entrained strip and the point at which there is exerted the pulling action.  This progressive dampening action has the effect of compensating and taking up the strong push which occurs when the strip is highly accelerated and subject to a rapid and violent pulling action.

Abstract: LUBRICATION CONNECTOR FOR ROLLER CONVEYORS Abstract of the Invention An improved lubrication connector is for roller conveyors of the type which includes a pair of idlers positioned end-to-end, each idler being rotatably mounted on a hollow shaft through bearing assemblies.  The shafts communicate with associated bearing assemblies, the bearing assemblies being lubricated by forcing lubricant through the hollow shafts. A flexible tube connects adjacent portions of the hollow idler shafts for transporting lubricant from one shaft to the other.  The improvement includes one end of the tube being held in place relative to one of the hollow shafts so that the interior of the tube will communicate with the interior of said hollow shaft, the other end of the tube being sized and shaped slightly smaller than the interior of the other hollow shaft for allowing the tube to be inserted in the shaft.  The other end of the tube is large enough to prevent lubricant under pressure from leaking between the tube and shaft, the tube having a flexibility sufficient so that the tube will deflect when the lubricant exceeds a predetermined pressure causing the other end to move outwardly in its cooperating hollow shaft.  Lubricant will then escape from the tube and shaft before the other end of the tube reaches the outer end of its cooperating hollow shaft.
