Title: Digital swing weight scale
Inventor: BAC MITCHELL E
IPC: A63B53/00
Filed: 2004-01-14
Abstract: A swing weight scale is presented that measures the swing weight of a golf club by measuring the torque exerted by the club about fixed balance point. The apparatus comprises an elongated torque arm pivotally mounted to a base. At one end of the torque arm a pair of rollers cradle the shaft of the golf club from underneath. At the other end of the torque arm a vertical stop provides a reference for locating the butt of the golf club shaft and provides the mounting surface for a second pair of rollers that cradle the upper surface of the shaft at the butt end. The rollers allow the golf club shaft to freely rotate about its longitudinal axis so that the golf club head will hang down freely. A torque sensor is mounted at the pivot point of the torque arm to measure the torque produced by the golf club as it is supported by the torque arm. A simple computer program converts the torque produced by the golf club on the torque arm into swing weights based on the known dimensions, weight and other parameters of the apparatus.

Title: Protective relay capable of protection applications without protection settings
Inventor: SCHWEITZER EDMUND O III
IPC: H02H7/30
Filed: 2004-04-07
Abstract: The current differential relay operates without adjustable settings, and includes a phase current differential element with a predetermined threshold, responsive to local phase current values and remote phase current values, to detect three-phase faults and producing a first output signal if the threshold value is exceeded. Either a negative sequence current differential element or two phase current differential elements, also having predetermined threshold values and responsive to the local and remote phase currents, detect phase-to-phase faults and phase-to-phase-to-ground faults and produces a second output signal if the predetermined threshold is exceeded. A negative sequence or zero sequence current differential current element, with a predetermined threshold value is responsive to the local and remote phase currents to detect phase-to-ground faults and to produce a third output signal if the threshold is exceeded. If any one of the first, second and third output signals occurs, a trip signal is generated and directed to the associated circuit breaker. The thresholds are selected to permit use of the relay in a wide range of possible applications.
