Patent number: 6168062Abstract: A slack puller has symmetrical sheave assemblies on each side of a cable path. The sheave assemblies each include a driven sheave mounted on an arm. When the sheaves are engaged with the cable by an actuator, tension in the cable pulls the sheaves in a way which tends to increase the compressional forces exerted by the sheaves on the cable. The self actuating nature of the slack puller allows compressional forces on the cable to be kept small until the cable comes under tension. The sheaves are driven by positive displacement hydraulic motors connected in series with a hydraulic pump. This permits the sheaves to turn quickly when the cable is not under tension and slows the sheaves as tension in the cable increases. The slack puller operates more quickly and causes less cable damage than conventional slack pullers. The slack puller has particular application in skyline logging operations where its compact size is an additional advantage.Type: GrantFiled: October 9, 1998Date of Patent: January 2, 2001Assignee: Enderby Manufacturing Corp.Inventors: William L.

Patent number: 6168067Abstract: A method for reducing material property degradation during friction stir welding. More specifically, the method includes the steps of solution heat treating first and second structural members at a first predetermined temperature schedule. The first and second structural members are then quenched to a predetermined temperature at which the structural members are in a nonequilibrium state and have an incomplete temper. The first structural member is then positioned adjacent to the second structural member, thereby defining an interface therebetween. Thereafter, the first and second structural members are joined to form a structural assembly by friction stir welding the material along the interface prior to precipitation heat treating the structural assembly. The structural assembly is then aged, such as by precipitation heat treating, at a second predetermined temperature schedule to stabilize the material properties of the resulting structural assembly, thereby completing the temper of the material.Type: GrantFiled: June 23, 1998Date of Patent: January 2, 2001Assignee: McDonnell Douglas CorporationInventors: Douglas J.

Patent number: 6168106Abstract: A fishing reel has a frame and an operating mechanism on the frame. The operating mechanism includes a spool assembly mounted to the frame for rotation around a first axis to direct fishing line onto the spool assembly. The operating mechanism also includes a brake assembly. The brake assembly includes a brake surface on the frame, a brake weight with a brake weight surface, and a first mechanism for mounting the brake weight to the spool assembly for movement between a) a first position wherein the brake weight surface on the brake weight is urged against the brake surface on the frame to generate a first braking force as an incident of the spool assembly rotating at a first predetermined velocity and b) a second position wherein the brake weight surface on the brake weight is not urged against the brake surface on the frame to generate a braking force as large as the first braking force.Type: GrantFiled: August 28, 1998Date of Patent: January 2, 2001Assignee: Brunswick CorporationInventor: Rayford Alan Cockerham

Patent number: 6168107Abstract: A restraining assembly for use in conjunction with a linear transducer. The restraining assembly comprises a plurality of spaced apart magnets positioned on a stationary frame, where the magnets provide a reverse torque and restrict excessive rotational speed on a spool when a copper disc or equivalent magnetic flux medium is rotated at a close proximity to the face of the magnets. When a cable is suddenly released and allowed to freely return on the rotating spool, the restraining assembly restrains the high rotational speed at which the cable can accelerate when returning or retracting to the spool, such that the restraining assembly prevents the cable from self-destruction and/or damage to the linear transducer.Type: GrantFiled: August 27, 1998Date of Patent: January 2, 2001Assignee: Celesco Transducer Products, Inc.Inventors: James A. Bishop, Jack H. Malek, Glen M. Ennis

Patent number: 6168108Abstract: A web tension control and apparatus uses a lightweight dancer and a control system that detects web tension using the dancer position as well as downstream sensors to maintain a relatively constant web tension. The control system also adjusts the braking force to an unwind roll based on the diameter of the roll, allowing for greater web tension control. A two-phase braking system prevents the unwind roll from spilling excess paper into the production line.Type: GrantFiled: November 20, 1998Date of Patent: January 2, 2001Assignee: Hallmark Cards, IncorporatedInventor: Robert E. Morley

Patent number: 6168109Abstract: An applicator stores a boxer's hand wrap substantially without folds, creases, or wrinkles, all of which are especially severe if the hand wrap is relatively stiff with dried perspiration. By storing the hand wrap in a smooth, rolled configuration, it can be readily reapplied in a similarly smooth, non-wrinkled manner, as is optimal for boxing purposes. The applicator has a spool and outwardly extending spindles. The spool is non-rotatable relative to the spindle, permitting the wrap to be appropriately tensioned while it is being applied to the boxer's hand. The applicator has deodorant which permeates the wrap when it is stored on a receiving surface of the spool.Type: GrantFiled: January 11, 1999Date of Patent: January 2, 2001Assignee: Balazs Inc.Inventors: Andrew R. Laudenslager, Peter B. Pecsvaradi
