Abstract: A system may receive orders from disparate sources, each order specifying at least one item located in a physical storage area divided into subareas. The orders may be prioritized for desired processing sequence. The system may determine, beginning with high priority orders specifying at least two items for each order, a virtual order footprint that represents all of the subareas corresponding to the items in the order and form a plurality of virtual potential pick batches, each virtual potential pick batch comprising orders in a unique virtual order footprint. When a configurable limit is reached, the number of orders in each virtual potential pick batch is determined. The order counts are a factor in determining which of the virtual potential pick batches are to be released for processing by available work resources. All other non-selected virtual potential pick batches are deconstructed awaiting the future availability of work resources.

Abstract: A vehicular drive shaft assembly is balanced about an axis of rotation. The vehicular drive shaft assembly includes a drive shaft tube having a first end and a second end, with a first tube yoke including a first radially outer wall fixedly mounted to the first end of the drive shaft tube. A first balance pendulum is located radially inward of the first outer wall and rotationally fixable relative to the first tube yoke, and a second balance pendulum is located radially inward of the first outer wall and is also rotationally fixable relative to the first tube yoke. The balance pendulums can be rotated before being locked in place in order to account for imbalances in the drive shaft assembly. A second tube yoke fixedly mounted to the second end of the drive shaft tube may also include balance pendulums, similar to the first, in order to provide additional drive shaft assembly balancing capabilities.

Abstract: This invention describes a method to efficiently identify to a worker needed boxes, totes or product for action. The invention does not require any special mechanical material handling equipment. The invention uses a battery powered addressable radio receiver (a “container pager”) that is individually attached to containers, storage locations or product. A “host” system generates a signal which is transmitted to an individually addressed receiver. When this signal is received by the addressed receiver, the “container pager” will either activate a light or other signaling means to alert a worker. The worker identifies the container that is being addressed and takes appropriate action. A variation of the invention includes a means for the container pager itself to active a transmitter in the container pager (two way paging).

Abstract: A driveshaft assembly is balanced for rotation during use by initially disposing an annular band about a portion thereof. The band is then secured to the driveshaft assembly, such as by welding, adhesives, frictional engagement, and the like. After the band is secured to the driveshaft assembly, one or more balance weights can be secured to the band, such as by welding, adhesives, and the like, at desired locations to balance the driveshaft assembly for rotation. The band functions as a mounting surface upon which the balance weights can be secured to balance the driveshaft assembly for rotation. Because the balance weights are secured not directly to the driveshaft assembly, but rather are mounted indirectly thereon by the band, the driveshaft assembly is protected from damage that might otherwise result from welding the balance weights directly thereto.

Abstract: A method of manufacturing a driveshaft for use in a vehicular drive train system includes the initial step of providing an inner tube including a portion having a plurality of splines formed therein. A portion of an outer tube is then disposed about the portion of the inner tube in an overlapping or telescoping manner, preferably in a press fit relationship. Next, portions of the outer tube are deformed radially inwardly about the inner tube. The radially inwardly deformed portions of the outer tube that extend between the external splines of the inner tube define internal splines on the outer tube. The internal splines formed on the outer tube cooperate with the external splines formed on the inner tube to provide a rotational driving connection between the inner tube and the outer tube, while normally preventing relative axial movement therebetween.

Abstract: An axially collapsible driveshaft includes a first driveshaft tube section, a connecting member having a first end portion that is secured to the first driveshaft tube section, and a second driveshaft tube that is secured to a second end portion of the connecting member. During normal operation of the drive train assembly, torque is transmitted through the driveshaft by means of the securement between the first driveshaft tube section, the connecting member, and the second driveshaft tube section. However, if a relatively large axial force is applied to the end portions of the driveshaft, either or both of the end portions of the connecting member are designed to fracture, allowing relative axial movement to occur between the first driveshaft tube section and the second driveshaft tube section. An annular recess may be formed in the connecting member adjacent to either or both of the end portions that are secured to the driveshaft tube sections.

Abstract: A method of manufacturing a collapsible driveshaft assembly includes the steps of disposing an end of a first tube within a forming die having a non-circular cross sectional shape, expanding the end of the first tube into conformance with the die cavity, inserting an end of a second tube is inserted within the deformed end of the first tube, and expanding the end of the second tube into conformance with the end of the first tube. As a result of this expansion, outwardly extending regions and inwardly extending regions of the second tube extend into cooperation with outwardly extending regions and inwardly extending regions of the first tube so as to cause the first and second tubes to function as cooperating male and female splined members. As a result, a rotational driving connection therebetween to form the driveshaft. When a relatively large axial force is applied to the ends of the telescoping driveshaft, the second tube will move axially within the first tube, thereby collapsing and absorbing energy.

Abstract: An annular two-piece thrust washer for use between the end wall of a bearing cup and the axially outer ends of the bearings and trunnion of a universal joint assembly includes a first piece and a second piece. The first piece is sized to be disposed between the axially outer ends of the bearings and the end wall of the bearing cup. In a preferred embodiment, a circumferential recess is formed at the junction between the radially inner surface and the axially outer surface of the first piece. The second piece of the thrust washer is sized to be disposed between the trunnion and the end wall of the bearing cup. When assembled, the second piece of the thrust washer is disposed within the first piece. The outer circumferential portion of the second piece extends into the circumferential recess of the first piece. A predetermined small clearance is provided between the first piece and the second piece which allows a limited amount of relative movement therebetween.

Abstract: An inserter assembly for inserting containers onto a storage carousel. The containers may be inserted by moving them horizontally in a direction tangent to a curved portion of the storage carousel. The container is then latched into the rack by raising a vertically movable horizontal lifting member to lift the lower outside edge of the container and tilt the container toward the carousel to engage a latching mechanism on the rack. The latching mechanism includes leading and trailing hooks with a smooth and continuous bottom surface, with the leading hook having an inclined wing sufficiently wide to rest on the upper leading inside corner of the container until it hangs over the inside of the container.
