Abstract: A method and apparatus for a ball and socket joint including a body member having an aperture coupled to a resilient ball container with a side wall extending from a first side of the body member to form an end portion. The side wall is disposed about at least a portion of the aperture wherein a ball disposed through the aperture is receivable in the resilient ball container. The resilient ball container has a substantially arcuate shaped inner surface portion with at least a portion of its side wall diameter less than a diameter of the ball, wherein the ball contacts and outwardly expands the side wall of the resilient ball container and draws the end portion of the resilient ball container toward the ball as the ball is inserted into and retained in contact with the resilient ball container to provide a strong, durable and tight fitting joint. A resilient retaining member disposed on the first side of the body member extends into the resilient ball container to constrict the aperture. The resilient retaining member is outwardly flexible for increasing the aperture to permit disposal of the ball through the aperture and into the resilient ball container, andl the resilient retaining member converges to constrict the aperture after the ball is inserted into the resilient ball container to retain the ball between the resilient ball container and the resilient retaining member to provide a strong, durable and tight fitting joint.

Abstract: An excavation tooth point longitudinally extending along an axis and having a pocket area extending inwardly through a rear end thereof is telescoped onto a nose portion of an adapter structure by inserting the nose portion into the tooth point pocket area.  The inserted nose portion has a tapered side opening therein that is positioned between a corresponding pair of similarly tapered tooth side wall openings.  The tooth point is removably coupled to the adapter nose using an elongated, wedge shaped connector member which is inserted, small end first, through the generally aligned tooth and adapter openings.  An internal passage longitudinally extends through the large connector member end and receives an inner portion of a force exerting member which compresses a spring within the passage, the spring in turn resiliently biasing an outer portion of the force exerting member into abutment with an interior surface portion of the tooth. The compressed spring, via the force exerting member, maintains the tooth point in an axially tightened orientation on the adapter nose, and automatically tightens the tooth further onto the adapter nose in response to tooth/adapter interface wear that would otherwise cause undesirable "play" between the tooth point and the adapter nose portion.  The connector member may be removed by pushing the force exerting member further into the connector member passage, rotating it, and then releasably locking it in this retracted position using a cooperating pin and slot structure on the connector and force exerting members.

Granted: 2006-06-27
Abstract: A process for the fluid catalytic cracking of heavy feeds under a heat balance regime is described, where one or more catalyst coolers external to the regenerator cool a stream of regenerated catalyst. A portion of said stream returns to the regenerator and a portion of the cooled regenerated catalyst is admixed to the non-cooled regenerated catalyst at a temperature substantially lower than the regenerator temperature, said admixture being brought into contact with the hydrocarbon feed to be cracked. As a result, the control of the catalyst circulation is rendered independent from the heat balance of the unit, with minimization of the thermal cracking, and therefore lower coke and fuel gas products.

Abstract: A method and apparatus (20) for forming coreless rolls (15) of pressure sensitive adhesive tape involves the use of a mandrel assembly (55) having a specific circumferential tape supporting segment (234) thereon for winding tape. The circumferential tape supporting segment (234) has a tape engaging surface portion (246) that, in a radial orientation, is compressible yet sufficiently stiff to support the tape as it is successively wound about the mandrel (55) to form a tape roll (15), and that is sufficiently pliant to permit ready axial removal of a wound tape roll (15) from the mandrel (55). The innermost wrap (72) of pressure sensitive adhesive tape about the mandrel (55) is masked by an adhesive liner (73). That liner (73) is formed from one portion of a liner/tab strip (123) which had been applied to the tape previously, and prior to winding, the tape is severed, and the remainder of that liner/tab (76) forms an end tab on the outermost end (75) of the previously formed coreless tape roll (15). The liner/tab strip (123) is applied by advancing the liner/tab material (90) laterally across the advancing web of pressure sensitive tape (26) adjacent a first adhesive bearing side (27) thereof, cutting the liner/tab material (90) to a length approximating the width of the web (26), urging the leading lateral edge portion (190) of the cut liner/tab strip (123) against the first, adhesive bearing side (27) of the advancing web (26) and urging the remainder of the liner/tab strip (123) against the advancing web (26) as the web (26) carries the liner/tab strip (123) away.

Abstract: A system for recovering ferrous metal components from waste materials includes a first magnetic separator (14) for magnetically separating ferrous metal components from waste material and an impacting device (16) for dislodging residual waste material from the surface of ferrous metal components separated by the first magnetic separator (14). The system may also include a second magnetic separator (54) following the impacting device (16), a water washing system (58) for cleaning ferrous metal components retained by the second magnetic separator (54), a ferrous metal collection station (60) and a waste material collection station (64). The impacting device includes a solid wall rotatable drum (22) having at least one radially inwardly projecting protuberance (46) on its interior surface. As the drum rotates, the protuberances (46) lift the ferrous materials separated by the first magnetic separator (14). Repeated impacts of the ferrous material with the interior surface of the drum (22) effectively dislodges waste material from the surface of the ferrous metal components without comminuting the ferrous material or subjecting the drum to aggressive wear and tear.
