Abstract: ABSTRACT          A thrust bearing for use with a shaft having a collar mounted thereon, comprises a base ring, a series of shoes positioned on the base ring and a shoe pivot on each shoe allowing the shoe to pivot in any direction.  An oil distribution groove is formed in the working face of each shoe near the leading edge of the shoe and extending radially for substantially the entire distance between the inner and outer diameter edges of the shoe.  A bleed groove extends radially from the inner end of the oil distribution groove to the inner diameter edge of the shoe for supplying oil to the inner diameter area of the shoe downstream of the bleed groove which downstream inner dia-meter area would otherwise be starved of oil by the centrifugal inertial effects of rotating the collar.  An oil supply hole for each groove extends axially through the base ring near the outer diameter edge of the base ring. An associated oil feed tube is connected between the oil supply hole and the outer end of the oil distribution groove near the outer diameter edge of the shoe. The oil feed tube has a near end with a ball shape and an annular recess with an O-ring seated in the recess, and a far end with a ball shape and an annular recess with an O-ring seated in the recess.  A socket is formed in each shoe and is connected to the oil distribution groove at its outer end for receiving the near end of the oil feed tube and its O-ring to seal the tube against oil leaks.  An equal number of sockets is formed in the base ring for receiving the far ends of the oil feed tubes and the associated O-rings to seal the tubes against oil leaks.  Shoulders are formed at the openings to the sockets for retaining the ends of the tubes in the sockets.  A retainer pin extends radially from each shoe into an annular groove in the base ring to assist in retaining the shoe on the base ring.

Abstract: TITLE Clutch Safety Features ABSTRACT OF THE DISCLOSURE A clutch where the output always comes to the same degrees of registry with the input is shown as including coaxial drive and driven members including a hub for mounting on a drive shaft.  The drive member is slidably mounted on the hub and rotatable thereby.  The drive member is formed with a multiplicity of ball-receiving cavities which are located radially inward of the periphery of the drive member.  The driven member includes a carrier member having a multiplicity of balls mounted thereon for engagement with the cavities.  The carrier member includes a flat, radial ring portion and an inner annular flange which provides a first degree of safety by tending to prevent any dislodged balls from the carrier member from travelling inwardly between the drive and driven members and tending to allow the dislodged balls to travel radially outward of the clutch. The carrier and drive members have intermeshing interface teeth.  The drive member is moved axially on the hub for engagement of the cavities thereof with the balls of the carrier member as the teeth of the drive member engage the teeth of the ball carrier to thereby rotate the driven member.  In its most preferred form, a second degree of safety is provided by having the maximum interface gap between the drive and driven members greater than the diameter of the balls to prevent any dislodged balls from jamming between the drive and driven members.

Abstract: HIGH TEMPERATURE PRESSURE SENSING                  INSTRUMENT AND METHOD                Abstract of the Disclosure This invention relates to apparatus and methods for filling a conventional Bourdon tube with an outgassed fluid to permit use of the Bourdon tube to measure fluid pressures  at  high  temperatures.    The  filling  device includes a hot reservoir containing hydraulic fluid that has  been  heated  to  facilitate  outgassing  and  a  cold reservoir in fluid communication with the hot reservoir to prevent exposure of the fluid in the hot  reservoir  to oxygen.   A vacuum line connected to the cold reservoir permits evacuation of the filling apparatus, the Bourdon tube and a typical bellows that may be attached to the Bourdon tube.  The bellows is mechanically compressed and provided with a center post to reduce the volume of the bellows by about fifty percent.  After the Bourdon tube, the bellows and the hydraulic fluid in the hot reservoir have been heated and outgassed, the vacuum is removed from the cold reservoir to permit hydraulic fluid to flow from the hot reservoir into the bellows and Bourdon  tube.          After the Bourdon tube and bellows are filled, the filling apparatus is disconnected from the fill port,  which is then plugged to prevent leakage.

Abstract: ABSTRACT                  Furrow Opener Operating Apparatus There is described a furrow opener apparatus capable of operating in a furrowing mode and a carrying mode.  The apparatus consists of a double acting hydraulic cylinder (10) having one end (20) connected to a furrow opener drag arm and the other end (D) connectable to a drill rig.  It incorporates a pressure cushioning system consisting of at least one pressure absorber and hydraulic lines communicating through a mode valve (12) with both the thrust draw sides (26, 28) of the double acting cylinder (10).  It further communicates through a single or double acting hydraulic valve (16,18) to the hydraulic pump (17) and reservoir (19) of an associated prime mover such as a tractor.  The mode valve (12) is hydraulically connected to both the thrust and draw sides (26,28) of the double acting cylinder (10).  In a first mode the mode valve (12) is hydraulically connectable to the pressure cushioning system and in a second mode hydraulically connected through a double acting hydraulic valve (10) to the hydraulic pump (17) and hydraulic reservoir (19) of the prime mover.  In use when the mode valve (12) is in the first mode the pressure absorber cushions forces transmitted hydraulically through the double acting hydraulic cylinder (10) from the openers and maintains a substantially constant pressure on both the draw and thrust sides (26, 28) of the double acting cylinder (10) to thereby create a net downward force from the ram (22) onto the furrow opener arm.  In the second mode the double acting hydraulic cylinder (10) is operable by the double acting hydraulic valve (18) to thrust or draw its ram (22) to respectively lower or raise the furrow opener drag arm.

Abstract: ABSTRACT OF THE DISCLOSURE          Each of a pair of heat exchangers in a combustion plant includes a storage space holding basic granules, and will alter-natingly be flowed through by combustion gas and air, respec-tively.  Residual heat from the combustion gas will be absorbed by the granules, and the moisture content of the gases will con-dense upon the granules.  Sulphur dioxide in the combustion gas will react with the basic material to calcium sulphite, and the moist granules will catch ash particles and other contaminants in the gas.  When valves have been re-set, air is made to pass through the granules, whereby it will be preheated.  The heated air may be conducted to a burner, to a regeneration apparatus for the granules, or through a conduit to the gas exhaust duct. After some time of operation the granules are transferred to the regeneration apparatus, which includes a rotatable drum, where the granules will be subjected to mechanical working and separa-tion of calcium sulphate and dust particles, preferably while being heated.

Abstract: ABSTRACT OF THE DISCLOSURE:           On encoding a cluster and run sequence comprising clusters of non-zero signal elements and runs of zero signal elements into a code sequence with application of a compression encoding scheme selectively to the clusters and without application of the encoding scheme to the runs, a mode code is used to indicate application of the encoding scheme to each selected cluster and to represent a zero signal element next preceding the selected cluster in a next predecing run,  In the code sequence, the mode code next precedes a succession of amplitude codes representative of the selected cluster and next succeeds a run length code preferably representative of that run length of the next preceding run from which the next preceding zero signal element is reduced,  Alternative-ly, the mode code may indicate switching between application and non-application of the encoding scheme to partial sequences each of which starts with a cluster next succeeded by a run, In either event, a particular code is preferably used to indicate an end of each run.  On decoding, the mode code is detected preferably with reference to the particular code to decide whether or not each amplitude code succession should be decoded according to an expansion decoding scheme which corresponds to the encoding scheme.

Abstract: "PRODUCT RECOVERY PROCESS"           A process is disclosed for the recovery of hydrogen and hydro-carbons from the gaseous effluent stream of a hydrogen-producing hydrocarbon conversion process.  The effluent stream of the reaction zone is partially condensed to remove the bulk of the heavy C6-plus hydrocarbons, which are then sent to a fractionation zone.  The remaining vapor is com-pressed to a substantially higher pressure.  The compressed vapor is then passed into a membrane separation zone in which a hydrogen-rich stream is separated from the compressed vapor.  The relatively high pressure non-permeate portion of the vapor stream which emerges from the membrane separation zone is partially condensed by autorefrigeration.  The still high pressure mixed phase fluid is separated into vapor and liquid hydro-carbon portions.  The liquid phase material is then flashed to produce coolant used to perform the partial condensation.
