  • Patent number: 6263382
    Abstract: A computer system is implemented according to the invention when an computer process interactively allows a user to configure a computer system. The device according to the present invention abstracts functionality common to all application specific computer configuration problems and locates it in a single framework. In this way, multiple application specific configuration processes can be developed easily without duplicating the work of creating common features.
    Type: Grant

  • Patent number: 6253318
    Abstract: A method implemented according to the invention relates to a method including the conversion between of logical requirements and physical requirements, including such devices as computer drive arrays, controller/storage box combinations, and conversion of virtual disk drive heights to physical disk drive heights. The methods of the invention can be applied to the configuration of most hierarchical system.

  • Patent number: 6248035
    Abstract: A rotary device comprising two elements (12, 20/22) supported for rotation about an axis (11) and movable relative to one another along said axis, and diaphragm spring means (33) urging said elements axially relative to one another, said diaphragm spring means having radially inner and outer portions connected respectively to said elements and arranged such that said elements are constrained to movement in opposite directions by the same or substantially the same distance as one another about an axially fixed position.

  • Patent number: 6033311
    Abstract: A constant velocity ratio universal joint of the tripode type including a first joint member having a first rotational axis and three tracks circumferentially spaced about the axis and extending lengthwise thereof. A second joint member is also included having a second rotational axis and three arms extending into the respective tracks of the first joint member. Each of the arms has a respective arm axis, and a roller is carried by each arm. Each roller has a roller axis and an external circumferential surface which engages opposite sides of the respective track in the first joint member. The external circumferential surface of each roller is a surface of revolution about the roller axis of a convex generally arcuate line having a meridian radius. The roller is characterized in that the meridian radius is greater than the equatorial radius.

  • Patent number: 5733197
    Abstract: A universal joint comprising a first joint member having a rotational axis and a body connected to the first joint member for pivotal movement relative thereto about a pivot axis intersecting and perpendicular to the rotational axis. The body comprises two trunnions extending along a trunnion axis perpendicular to the pivot axis of the body and respective rollers are carried by the trunnions for rotation about the trunnion axis. The universal joint also comprises a second joint member having a rotational axis and affording two tracks extending lengthwise of the second joint member and diametrically opposed to one another about the rotational axis of the second joint member with the rollers being received in the tracks for torque transmission between the joint members by way of the body and rollers.

  • Patent number: 5645487
    Abstract: A constant velocity ratio universal joint of the tripode type includes an outer joint member with three tracks extending lengthwise of the joint member, and an inner joint member having three arms extending outwardly into the tracks of the outer joint member. Each arm carries a respective roller having an external surface which engages opposed side portions of the associated track. Each roller is able to tilt within its associated track and move therealong so that the inner and outer joint members are able to move axially relative to one another and undergo relative articulation.

  • Patent number: 4992020
    Abstract: A lifting attachment for securing to lifting arms of a front end loader has a pair of attachment brackets pivotally connected to the lifting arms, A vertical I-shaped solid plate rear wall carries the attachment brackets in a fixed relationship thereto. A top solid plate is angularly attached to the vertical rear wall, inclining downwardly and extending forward from the rear wall. A plurality of supporting plates support the top plate from the bottom, forming a "wedge-shaped" lifting element which has no side walls extending upwardly from the top plate, thus forming no restrictions to the lateral size of loads which can be handled by the lifting attachment.
