Title: Erosion resistant soft seated valve trim

Granted: 1987-08-18
Abstract: EROSION RESISTANT SOFT SEATED VALVE TRIM            Abstract of the Disclosure The disclosure is related to a high pressure fluid control valve including a valve seat made from a resilient, deformable material and a main valve plug which is matable with the resilient, deformable valve seat. A selectively, axially displacable valve stem is associated with the valve plug whereby a contact load placed upon the valve plug by the valve stem will cause the valve plug to be become imbedded within the deformable material comprising the valve seat when the valve is closed and thereby conform the deformable seat precisely to the contour and configuration of those portions of the valve plug which mate with the valve seat. In this manner, a precise zero-leakage mating is obtained each and every time the plug is mated with the seat. In accordance with the invention, an auxiliary throttle plug is associated with the main valve plug and is arranged to mate with a second, metal valve seat which is arranged in an area removed from the resilient, deformable valve seat. The axial movements of each of the valve plug and the throttle plug are coordinated in a manner whereby the primary throttling areas for the fluid flow, particularly during valve opening and valve closing operations are displaced to portions of the valve structure which are remote from the resilient, deformable valve seat.

The mix-ture is flowed into a mold cavity under heat and pressure prior to any significant cross-linking agent-induced cross-linking during a first portion of the molding cycle.  During a second portion of the molding cycle, the cross-linking agent is released to effect substantially all cross-linking agent-induced cross-linking.  The cured mixture is removed from the mold cavity to provide a silicone rubber product.

Abstract: Abstract A control system for a hydroelectric power plant of the run-of-river type wherein the load on the turbine-generator units is matched to the flow of the river so that the units operate at the maximum head available for existing flow conditions to produce the maximum energy available from the river flow for the installed capacity of the plant and within the allowable, safe operating capability range of the turbine-generator units.  Reservoir water level sensors provide a signals indicative of changing water level, sensors for generator electrical and thermal operating characteristics provide a signals related thereto, and a control connected to the water level sensors, to the generator sensors and to the turbine governor adjusts the turbine flow control devices to change the turbine power in response to changing river level within the safe and allowable operating range of the generator.  Adjusting the turbine power to match the water available either when the reservoir level increases or decreases maintains maximum when a for the power plant to obtain maximum energy therefrom.  A tailwater level sensor and cavitation control also control the turbine flow control devices in an appropriate manner when a condition of cavitation is being approached.  The control system typically is employed with a plurality of turbine-generator units in a hydro-electric power plant.

Abstract: ABSTRACT: "Signal analysing and synthesizing filter bank system"     In a signal analysing and synthesizing filter bank system, the analysing bank receives a signal sampled at the rate fe and produces N contiguous subband signals sampled at the rate fe/N. From the subband signals the synthesizing bank must recover the incoming signal. These filter banks are formed by modulation of a prototype filter by sinusoidal signals which, for subband k (0 ? k ? N-1), have a frequency (2k+1)fe/(4N) and respective phases +(2k+1).pi./4 and -(2k+1).pi./4 for the analysing and syn-thesizing banks. These signals are furthermore delayed by a time delay (Nc - 1)/2fe), where Nc is the number of coefficients of the prototype filter. Preferably, the analysing bank is realized by the cascade arrangement of an N-branch polyphase network (12) and a double-odd discrete cosine transform calculating arrangement (14) and the synthesizing bank is realized by the cascade arrangement of a double-odd discrete cosine transform calculating arrangement (15) and an N-branch polyphase network (17); Fig. 4).

Abstract: Birdswing Defect Detection for Glass Containers ABSTRACT OF THE DISCLOSURE      Method and apparatus for detecting "birdswing" flaws in glass containers.  A container is illuminated using a beam of light introduced at its base. The column of light passes up through the container along its inner sidewall until it impinges upon a birdswing or like defect at the inner wall, which will cause light rays to be reflected through the outer wall.  The light rays advantageously illuminate a zone at the base of the bottle which does not extend beyond the outer side wall, and are evenly distributed over a defined range of incident angles.  Light reflected through the outer sidewall is detected as a bright spot by a suitable photodetector array, which monitors the entire container sidewall.  This inspection technique effectively eliminates undesired indications of defects within the container wall, as well as of patterns embossed on the outer surface.
