Patent number: 7409997Abstract: A centrifugal pump has impellers for pumping low flow, high viscous materials. The impellers have high exit angles greater than 30 degrees and preferably greater than 50 degrees. The impellers and diffusers have specific geometry that varies with viscosity. The pump has zones of impellers and diffusers with the exit angles and geometry in the zones differing from the other zones. The exit angles decrease and geometry varies in a downstream direction to account for a lower viscosity occurring due to heat being generated in the pump. One design employs small diameter impellers and high rotational speeds.Type: GrantFiled: September 22, 2004Date of Patent: August 12, 2008Assignee: Baker Hughes IncorporatedInventors: Farral D.

The resilient member has at least one protrusion extending axially thereon to reduce the amount of surface contact between the resilient member and the hub member or the inertia member. A method for tuning dampers is also disclosed wherein reducing the amount of surface contact between the resilient member and the hub member and inertia member allows the damper to achieve lower part frequency based primarily on the geometry of the resilient member.Type: GrantFiled: June 4, 2004Date of Patent: August 12, 2008Assignee: Metaldyne Company LLCInventor: Michael S. Crissy

Patent number: 7410036Abstract: A brake-disc/hub assembly is provided with a disc/hub connection for connecting a brake disc to a brake disc hub. The brake disc includes support elements on the inner circumference thereof, the brake disc hub is provided on the outer circumference thereof with cams, and intermediate elements are radially distributed in the circumferential direction between the brake disc hub and the brake disc, extending into cavities running in the circumferential direction between the cams and the support elements and, hence, providing a transfer of the braking force from the brake disc to the brake disc hub. Each intermediate element includes two shoulders running at least completely or essentially in parallel to each other, whereby one shoulder contacts a corresponding cam and the other shoulder contacts a corresponding support element, embodied such that the total thickness of opposing shoulders on the elements may be reduced for disassembly thereof.Type: GrantFiled: September 12, 2006Date of Patent: August 12, 2008Assignee: Knorr-Bremse Systeme fuer Nutzfahrzeuge GmbHInventors: Josef Wimmer, Josef Schropp

Patent number: 7410038Abstract: A locking unit for the locking of the movement of a piston. An electromagnet is provided the armature, respectively the armature bar, of which acts on an operating element. The operating element co-operates with a catching element in such a way that the catching element blocks in a locking position the movement of the piston, respectively the catching element unlocks in an unlocking position the movement of the piston. Catching element and operating element co-operate surface-to-surface.Type: GrantFiled: October 8, 2003Date of Patent: August 12, 2008Assignee: SVM Schultz Verwaltungs-GmbH & Co.

Patent number: 7410039Abstract: A tunable vibration absorption device is provided that is suitable for active or semi-active vibration absorption or damping of vibrations in vibrating structures. It comprises a stack including a force actuator mechanism for generating an axial actuation force and a force sensor mechanism which is responsive to an external force acting on the stack to generate a force signal. A controller unit is electrically connected to the force sensor mechanism for receiving the force signal generated by the force sensor mechanism, and it is also electrically connected to the force actuator mechanism for adjusting the axial actuation force generated by the force actuator mechanism in response to the received force signal generated by the force sensor mechanism.Type: GrantFiled: February 4, 2005Date of Patent: August 12, 2008Assignee: ASM Assembly Automation Ltd.Inventors: Siu Wing Or, Lai Wa Helen Chan-Wong, Ping Kong Joseph Choy, Chou Kee Peter Liu

Patent number: 7410040Abstract: An actuator for selectively causing axial compression of friction elements in a clutch is disclosed. The actuator comprises a pair of beveled wedge washers and a bearing race supported between the washers. The race supports conical bearing rollers in a generally radial orientation. An actuator plate is mounted for rotation relative to the bearing race and includes bearing ramp surfaces that are operable to move the conical bearing rollers radially inwardly thereby forcing the washers to move apart axially and to thereby cause compression of and torque transfer through the friction elements. A clutch including the actuator is well suited for inclusion in a transfer case.Type: GrantFiled: December 21, 2005Date of Patent: August 12, 2008Assignee: DYMOS Co., Ltd.Inventors: Dan M. Stefan, Thomas C. Bowen, Jason R. Davis

Patent number: 7410042Abstract: A pump includes a cam member and an armature plate received on an input shaft rotatably supported with a differential housing of a clutch. The pump also includes a cylinder rod slidingly received in a chamber of a master cylinder to pressurize a hydraulic fluid. The cam member includes a ring and a back plate. The ring has an outer, preferably symmetrical, surface with a variable radius defining a ramped portion for outwardly driving the cylinder rod when the cam member is rotated either forward or backward with respect to the differential housing. A coil generates an electromagnetic field when activated drawing the cam member towards the armature plate such that contact forces causes the cam member to rotate with the armature plate. A roller disc is rotatably supported at one end of the cylinder rod for rolling contact between the cylinder rod and the cam surface of the cam member ring.Type: GrantFiled: June 8, 2006Date of Patent: August 12, 2008Assignee: The Hilliard CorporationInventors: David C. Ochab, Brendan Brewer, Matthew J. Cowen, Kelly P. Heath, John M. Hasson, Jr.

Patent number: 7410044Abstract: An article carrier (1) includes a mount (3) for mounting the article carrier to a conveyor. A carrier frame (4) is located over the mount and is movable about a pivot (5) so as to be locatable in a carriage position, in which articles (2) may be supported on the carrier frame (4), and an ejection position, in which articles (2) are ejected from the carrier frame (4). The apparatus further includes a locking member (6); wherein when the carrier frame (4) is located in the carriage position, the locking member (6) is locatable in a first position that prevents movement of the carrier frame (4) about the pivot (5) and is movable into a second position that releases the carrier frame (4), allowing the carrier frame (4) to move about the pivot. When the locking member (6) is located in the first position to prevent movement of the carrier frame, the locking member is not under load. The article carrier (1) may be used as part of a grading apparatus.Type: GrantFiled: January 30, 2004Date of Patent: August 12, 2008Assignee: Anzpac Systems LimitedInventor: Hamish Alexander Nigel Kennedy
