  • Patent number: 4581104
    Abstract: An exothermic reaction of a gas with a gas permeable material is performed in a retention vessel. Temperature control of the exothermic reaction is obtained by recirculating the gas from the top of the vessel downwardly through and co-current to the gas permeable material and removing the downwardly flowing gas at a point above the bottom of the reactor and simultaneously recirculating gas which has been cooled into the bottom of the reactor, upwardly through and counter-current to the gas permeable material and removing the gas at a point above the bottom of the reactor.

  • Patent number: 4523362
    Abstract: A protrusion is formed on the free end of an axially extending lip of an outer race member. The free end of the protrusion is axially and radially spaced from the free end of the remaining part of the axially in-turned lip to permit the passing of a reduced end of a reduced end roller. The reduced end rollers are inserted into the outer race member through the protrusion. After all the rollers are in place within the outer race member the free end of the protrusion is closed by heating the protrusion and pressing the protrusion to provide an in-turned lip of substantially the same shape throughout the circumference of the lip.

  • Patent number: 4516302
    Abstract: The apparatus for separating a solid-liquid mixture has a housing with a metal screw conveyor adapted to rotate relative to the housing on a common longitudinal axis. The conveyor has helically-formed flights about its axis. Replaceable inserts are mounted on the entire circumference of the flanks of the flights with each insert having metal secured to the flights and integral wear-resistant material adapted to function as the working surface.The inserts are formed by first making a metal annular member of the same material as the conveyor flight. The wear-resistant, hard-facing material is then deposited on one radial surface of the metal annular member in a manner to simultaneously form and fuse the wear-resistant, hard-facing material to the annular member. The metal part of the annular member is then machined to proper dimensions and the annular member cut into segmental inserts. The segmental inserts are then mounted on the conveyor flights.

  • Patent number: 4515693
    Abstract: A solid, fiberglass-reinforced plastic rotary drum filter includes a first solid fiberglass-reinforced head at one end and a second solid fiberglass-reinforced head at the other end. A central solid fiberglass-reinforced plastic pipe extends from one plastic head a predetermined distance into the plastic drum. A plurality of radial, solid fiberglass-reinforced plastic drainage conduits extends from the solid fiberglass-reinforced plastic deck of the plastic drum to the central pipe. The longitudinal separation between the radial plastic drainage conduits and the first plastic head is carefully chosen and the dimensions of the first plastic head are such that the first plastic head is strong enough to withstand the head-bending force due to radial force, drive torque, and hydraulic end force.

  • Patent number: 4498888
    Abstract: The driving shaft has an end shaped to overlap the end of the driven shaft. The two shafts are interconnected by a coupling member. The coupling member is connected to the driven shaft by a long pin. The overlapping portion of the driving shaft is connected to the coupling member by two short pins.

  • Patent number: 4480392
    Abstract: The dryer includes at least one vessel, means for heating the outside of the vessel to dry wet material in the vessel and a gas inlet in the lower section of the vessel.The pressure of the gas fed to the gas inlet is predetermined and transports the material through the vessel in the form of a loose material bed. The dried material is removed from the vessel.A high pressure gas pulse generator feeds pulses into the vessel to agitate the material in the loose bed to prevent compaction of the material, and avoid channeling through the loose material bed. The motion of the loose material destroys vapor film on the inside shell of the vessel to maintain good heat transfer through the shell.

  • Patent number: 4479786
    Abstract: The rotatable shaft assembly includes an elastomeric bushing which is provided in the space between an outer rotatable driven member and an inner rotatable driving member. The bushing transmits the rotation of the driving member to the driven member. Should the elastomeric bushing material fail or be subjected to excessive torque or axial force, a fail-safe washer transmits the rotation of the driving member to the driven member, and a retention washer prevents the axial disengagement of the driving member from the driven member.

  • Patent number: 4469380
    Abstract: The linear movement bearing has an inner race and an outer race. The outer race has a plurality of circumferentially-separated axially centered lands on its inside periphery.An annular retainer is provided in the space between the inner race and the outer race. The retainer has a plurality of circumferentially-separated pockets. A separator is centrally located within each of the pockets to form axially-extending pairs of first and second guideways and reversing guideways at the axial ends of and interconnecting each pair of first and second guideways to form continuous closed paths. Rolling members fill each continuous closed path.All rolling members always contact the inner race. The lengths of the outer race lands and the circumferential separation of the lands are such that the rolling members in the first guideways contact the lands while the rolling members in the second guideways and reversing guideways do not contact the outer race.

  • Patent number: 4456313
    Abstract: Each roller in a roller bearing has varying diameters along its length. The longitudinal surface is formed along varying radii of curvature. The diameters are functions of the contact stress along the roller, the length of the roller, any angular misalignment, and the effective diameter of the bearing. The varying diameters are such that a uniform contact stress is placed on each roller.If desired instead of the rollers, a race may be shaped to cause the uniform contact stress.
