    摘要: A braking control circuit for an alternating current motor is disclosed as having a winding and adapted to be coupled to an energizing control circuit for connecting a source of AC voltage to and for disconnecting the source of AC voltage from the winding. The braking control circuit comprises a selectively controlled rectifier operative in a first conductive mode for applying rectified current to the winding to brake the motor and in a second non-conductive mode, and a switching circuit coupled to the rectifier and responsive to the disconnecting of the source of AC voltage from the winding for switching the rectifier between its first and second modes at a first switching rate to brake the motor rotation at a corresponding first braking rate, and thereafter for switching the rectifier between its first and second modes at a second switching rate different from the first switching rate to brake the motor at a corresponding second braking rate.

    摘要: A protection system is provided for an electrical power network. The system has one or more circuit breaker arrangements which on activation isolate electrical faults within the network, and one or more fault detectors. The or each fault detector measures an inductance of a respective section of the network. The system is configured to activate one or more of the circuit breaker arrangements in response to measured inductances which are indicative of a fault.

    摘要: A DC electrical power system has a power generator converter system, a positive supply rail extending from the converter system, a negative supply rail extending from the converter system, and a midpoint earthing arrangement operatively connecting to the supply rails. The earthing arrangement is connected to earth by a solid earth connection. The network further has a first protective device on one of the supply rails which in case of a fault is operable to interrupt current flowing on that rail, and a second protective device on the earthing arrangement which in case of a fault is operable to interrupt current flowing to earth through the solid earth connection.

    摘要: A face or face insert (40) for a golf club head (20) is disclosed herein. The face (40) has an interior surface (40a) with a first thickness section (200) and a second thickness region (205). The first thickness section (200) preferably has a thickness that is at least 0.025 inch greater than the thickness of the second thickness region (205). In a most preferred embodiment, the first thickness section (205) has a X shape. The face or face insert (40) with variable thickness allows for a face or face insert (40) with less mass in a golf club head (20) that conforms to the United States Golf Association regulations.

    摘要: A golf club head (20) having optimized inertial properties and center of gravity is disclosed. The golf club head (20) preferably has a volume between 300 cubic centimeters and 500 cubic centimeters. The golf club head (20) has a center of gravity located less than 1.7 inches from an exterior surface of a front wall (30). The positioning of the center of gravity of the golf club head (20) and the optimized inertial properties provide the golf club with greater ball spin robustness and better performance.
