  • Patent number: 9827472
    Abstract: A golf club includes a tubular shaft, a golf club head affixed to a first end of the tubular shaft, and a grip abutting a second end of the shaft. The golf club further includes an adjustable counterbalance that is insertable within a hollow recess of the grip. The adjustable counter balance includes an elongate member adapted to be secured to the tubular shaft, and a movable weight. The movable weight is selectively transitionable between a first, unlocked state that permits translation of the weight along the elongate member, and a second locked state that restrains the weight from free translation.

  • Publication number: 20060174844
    Abstract: An animal stanchion having fixed stanchion structure and a pivotal release stanchion laterally spaced apart to define a head opening. The animal stanchion further comprises an upper top control rail which is configured to interact with a latch to selectively hold and release various portions of the pivot rod from connection with the latch. This device further comprises a plurality of individual locking brackets which are configured to interact with handle catch devices so as to hold various devices within their designated location within the device.

  • Publication number: 20050074048
    Abstract: A method of estimating an internal temperature of a vehicle battery is based on heat transfer between a heat source and the battery. In addition to the heat source, airflow generated by vehicle movement and radiator fans affects the internal temperature of the battery. The method estimates an initial internal temperature of the battery at engine startup based on how long the engine was off. The temperature of the heat source is determined. A transfer function is determined to represent the effect of the airflow. The method updates a current internal temperature of the battery based on the initial internal temperature and an integration of the transfer function and the heat source temperature.

  • Patent number: 6318297
    Abstract: A livestock free stall is provided, having a pair of vertically oriented posts held in fixed spaced relationship. Each of the posts has attached thereto in parallel spaced relationship upper and lower receiver tubes or posts with the receiver tubes or posts of each stanchion oriented in parallel spaced relationship to the corresponding upper and lower receiver tubes or posts of the other stanchions. A pair of rail loops, each having upper and lower ends, are then configured and sized for insertion into the upper and lower receiver tubes, or for receiving the upper and lower receiver posts, is then attached and fastened to the stanchion. A top rail interconnects the posts to form the completed free stall assembly.

  • Patent number: 6082306
    Abstract: A stanchion bumper is provided for use with a cattle stanchion having a head opening typically defined by a stationary, vertically-oriented stanchion and a pivotal release stanchion which, when tilted in one direction, enlarges the upper part of the opening so that the animal can insert its head through the opening, a closed position where the pivotal stanchion is vertical and defines a head opening through which an animal cannot withdraw its head, and a downed animal position wherein an enlarged lower opening exists so that a downed animal can withdraw its head. The stanchion bumper is positioned below the pivot point of the release stanchion, such that the lower portion of the release stanchion will engage the stanchion bumper when the animal inadvertently moves the release stanchion past the closed position toward the downed animal position.

  • Patent number: 5878697
    Abstract: An animal stanchion having fixed stanchion structure and a pivotal release stanchion laterally spaced apart to define a head opening and a latching mechanism which includes a first latch coupler attached to the fixed stanchion structure for receiving and releasably holding a second latch coupler and a control rod mounted adjacent to the first latch coupler for rotatable positioning to a first position to make contact with the second latch coupler at any point along the control rod's longitudinal axis to release it and to rotate to a second position to permit engagement of the second latch coupler with the first latch coupler.

  • Patent number: 4976224
    Abstract: A double hinged cattle stanchion (10) is disclosed and includes a pair of release stanchions, a "J" shaped fulcrum stanchion (15) and a release stanchion (14), both of which are pivotally attached between a pair of fixed stanchions (13). Fixed stanchions (13) are attached in upright pairs between a horizontally extending top rail (11) and a horizontally extending bottom rail (12). Fulcrum stanchion (15) includes a main elongated portion and a perpendicularly depending leg member. A fulcrum offset member (16) is perpendicularly attached at a midpoint along the main elongated portion and includes a fulcrum bracket (17) at its extending end. Fulcrum bracket (17) provides a pivotal attachment point for release stanchion (14) via a standard pivot bolt (18). The extending end of the depending leg portion of fulcrum stanchion (15) is pivotally attached to a base bracket (20) located between a pair of fixed stanchions (13) on bottom rail member (12).
