Title: Waterwheel
Inventor: PENELOPE JANE CARRUTHERS
IPC: F03B7/00
Filed: 2016-06-20
Abstract: A breastshot waterwheel 1 has a plurality of paddles 23, 27, 28, 29, each of the paddles being in communication with the incoming water flow 7 for a portion of the rotation cycle of the waterwheel about its axis. During the water receiving portion of the rotation cycle for each paddle, the incoming water 7 flows onto a water receiving surface of the paddle 23. A first, upstream end of the water receiving surface is configured such that the water flows in a substantially horizontal direction across the first end of the paddle. The paddle is curved so that at least a portion of the water flows onto a downstream portion of the paddle and changes direction, thereby exerting a force on the paddle causing the waterwheel to rotate about the axis. The tangential velocity of the first end of the paddle is less than a speed of the incoming water flow.

Title: A method of operating a motor drive circuit
Inventor: RAYMOND JOHN PETO
IPC: H02P27/04
Filed: 2017-07-25
Abstract: A motor drive circuit is operated by adjusting; a shape, and/or an amplitude, and/or a frequency of an input voltage wave for use as an input drive for a non-synchronous machine (e.g. motor, generator, alternator). An optimum value is used for deriving a feedback signal, indicative of minimum total of drive and motor losses. The method includes iteratively seeking; a preferred input voltage wave shape, and/or input voltage, and/or input voltage frequency for a specific motor speed and load, whilst taking into account any drive and motor losses. The method may be used to control an induction motor, a permanent magnet motor (PMM) or a switched/variable reluctance motor. Adjusting the applied voltage, frequency and slip of the motor to a sweet spot combination provides a given motor output power and speed for the least power supplied to the input of the drive.

Title: Identifying electrical cable connections
Inventor: FABRICE SERRANO
IPC: G01R31/04
Filed: 2017-11-27
Abstract: A computer-implemented method for identifying electrical cable connections comprises obtaining one or more infrared pictures of the electrical cable connections, detecting thermal signatures of the connections in the images, and using the detected signatures for identifying electrical cable connections. The infrared signature may be passive, i.e. obtained through normal heating of the cable connection by current flow, or it may be dynamically generated, e.g. by changing current to produce a known infrared emission signature. Redundant power supplies may be shut down or the activity of a device attached to the cable may be increased or decreased to produce the signature. The infrared images may be compared to visible light images to assist in identifying the connections. The thermal image may be obtained using a thermal camera connected to a mobile device.
