摘要： Apparatus and a method of protecting the lateral edges of a conveyor belt. A resilient tubular member having a longitudinal slit therein is in resiliently maintained contact with the belt adjacent lateral edges. The resilient member may have portions of its inner surface spaced from the belt edge portions so as to define a number of cushioning air spaces therebetween. The resilient members are preferably of generally circular cross sectional configuration in unexpanded condition and are generally coextensive with the belt. The belt may have recesses for receipt of the slit ends of the tubular resilient member. The method may involve providing an elongated tubular resilient member which is slit longitudinally and circumferentially expanded so as to permit it to receive a lateral edge of the belt. The interengagement may be maintained through resiliently maintained contact alone or by additional means for securing such contact.

摘要： An improved heat responsive backseat for gate valves which includes a rotating valve stem (50) carried by a bonnet assembly (14) for actuation of a gate member (40). A fusible stem ring (126) supports the valve stem at an outer portion thereof (68) within a roller bearing chamber (56) of the bonnet assembly. The valve stem (50) moves axially outward from the valve chamber (20) when the fusible stem ring (126) melts due to an external fire condition to bring a valve stem backseat portion (64) into sealing engagement with a bonnet seat portion (54). The valve stem (50) moves axially outward from the valve chamber (20) independently of roller bearings (74, 76) contained within roller bearing chamber (56) such that the roller bearings (74, 76) remain axially fixed with respect to the bonnet assembly before, during and after the shifting of the valve stem. Therefore, the valve stem may be easily rotated after the fire condition has been extinguished without the occurrence of cocking or wedging between the bearing means and valve stem. Accordingly, a secondary metal-to-metal seal is provided between the valve stem (50) and bonnet assembly (14) such that if the primary packing (104) is destroyed by the fire condition the gate valve will not leak flowline fluid exteriorly of the gate valve.

摘要： Fluidized bed systems for segregating cleaning or classifying particulate matter of differing physical properties such as particle density or size. Multiple stage beds preferably operate in a partially fluidized state and the classification structure provides for full peripheral discharge of both floats from the upper portion of each bed and sinks from the lower portion of each bed to alleviate the tendency of fluidized medium to both short circuit the particles of the upper stage and restrict the flow of particles from the upper stage to the lower stage.

摘要： A high pressure sealing connection for sealing between coaxially aligned members (22, 10) which are connected by metal bolt means having a different coefficient of thermal expansion from the aligned members. The connection comprises a metallic sealing ring (40) having at its largest external diameter a curved arcuate peripheral surface 52 characterized by a center of curvature which is co-diametral with the center of the seal ring but may be of greater or lesser radius than the radius of the ring. At its inner periphery, upper and lower flanges (61, 62) extend inwardly and perpendicularly to the axis of the ring. The coaxially aligned members (22, 10) are provided with recesses defined by opposed internal frusto-conical sealing surfaces (41, 42) at their adjoining ends, each tapering inwardly from the end of the member to an annular shoulder (43, 44) in the bore of the aligned member. The frusto-conical surfaces (41, 42) are of equal taper in the range of 5 degrees to 20 degrees. Drawing the coaxially aligned members together by suitable bolt means (31) results in a compression of ring (40) and a sealing relationship between the ring and the aligned members which is enhanced by fluid pressure energization. The internal flanges (61, 62) significantly increase the elastic zone of the ring to include the flanges themselves which continue to urge the seal ring in sealing engagement with the aligned members even after high pressure or temperatures have caused a deformation of the sealing ring or the aligned members. The curved outer surface of the seal ring in conjunction with the tapered frusto-conical surfaces of the seal grooves permits the points of sealing contact to roll as the geometry changes with differential thermal expansion.

摘要： A crossover seal assembly (44) for sealing the annulus between a well casing (16) and tubing head (22). The assembly includes spaced pairs of upper and lower metal seal rings (60 and 72, 108 and 120) having matching frusto-conical wedging surfaces (70 and 74, 118 and 122) which interact when an axial compressive force is applied to thereby effect a controlled radial expansion of the seal rings to sealingly engage the inner and outer cylindrical surfaces (48, 47) of the tubing head (22) and well casing (16). The axial compressive force is mechanically applied by a plurality of holddown lock screws (90) which interact through tapered conical tips (94) to energize the crossover seal assembly (44).

摘要： A high pressure in-line test valve (42) is positioned to block off a first fluid pressure source (10) acting on a control valve means (32 and 34) and to provide communication with an alternate test fluid pressure source (138) for testing the control valve means. The test valve (42) has a central bore (70) in which a depressible piston (78) is positioned for longitudinal movement between a seated extended position (FIG. 2) blocking the first fluid pressure source and simultaneously communicating test fluid to the control valve means, and an unseated retracted position (FIG. 3) re-establishing communication between the first fluid pressure source and the control valve means and simultaneously blocking the alternate fluid pressure source (138) with a dual sealing means. The dual sealing means includes a primary metal-to-metal sealing member (84 and 114) and a secondary annular sealing member (120) providing a test valve that is capable of withstanding high working pressures such as 20,000 pounds per square inch without leaking fluid from the first fluid pressure source ( 110) to the alternate fluid passage (104) or externally of the test valve. The dual sealing means are releasable upon engagement of a hollow stinger (124) which actuates the piston (78) into its seated position and provides a connection means (134) to supply a test fluid from an alternate fluid pressure source (138) for testing of the control valve means (32 and 34).
