Title: Improvements to the operation of electromagnetic actuators
Inventor: HUGH-PETER GRANVILLE KELLY
IPC: H01F7/18
Filed: 2017-10-31
Abstract: An electromagnetic actuator 10 comprises a coil 12 and a permanent magnet plunger 12a and means 20 or preventing, or reducing to an extent desired, the circulation of currents caused by motion of the plunger 12a within the coil 12, once power applied to the coil has been switched off. The means 20 may be a Zener diode with a conduction voltage sufficiently low, 25 to 40 volts, to permit high voltage spike back emf signals to induce current flow through the coil 12 but sufficiently high to prevent, or reduce, the current circulation that could be induced by the motion of the permanent magnet plunger 12a within the coil 12. Alternatively, a circuit, possibly comprising a capacitor connected in series to a resistor, may be used to prevent, or reduce, the current circulation that could be induced by the motion of the permanent magnet plunger within the coil. The actuator 10 may include a FET transistor, for applying power to the coil 12, and a diode connection between the FET and the coil. The actuator 10 may have a housing which has means, such as slits, to prevent or limit eddy currents which could be induced by the motion of the permanent magnet plunger 12a. The actuator 10 may be used in a grabber of an amusement arcade machine.

Title: Water softener apparatus
Inventor: WILLIAM ROBERT SARGEANT
IPC: C02F5/00
Filed: 2018-05-10
Abstract: A water softener apparatus comprises two water softener tanks 1, 2, a valve 11 controlling the flow of water and a water-driven flow meter 16 for controlling the valve to cause the water softener tanks to be rendered inoperable to soften water at respective different intervals so that at least one water softener tank is operable all the time. After a set volume of water has passed through one tank, water is passed through the other tank. The water softener tanks can be ion-exchange tanks which may be regenerated by brine when not softening hard water. The flow meter preferably comprises an actuator which moves in a cyclic movement in response to the flow of a set quantity of water and can actuate two service valves 27, 28 which send pressured water signals to a drain shuttle valve. The drain shuttle valve may then divert hard water from one tank to another and initiate regeneration of the first tank. A regeneration meter 23 terminates the alternate regeneration of the two tanks. The regeneration meter is positioned in the apparatus downstream of a point where brine for regeneration of the two water softener tanks is received into the apparatus.

Title: An adaptive sliding-mode control method of the permanent magnet synchronous motor based on dynamic surface technology
Inventor: SHAOHUA LUO
IPC: H02P21/00
Filed: 2018-05-24
Abstract: An adaptive sliding-mode control method of a permanent magnet synchronous motor is based on dynamic surface technology. The method comprises: establishing a standardized model of the motor with time-varying delay, and applying a single-weight RBF (Radial Basis Function) neural network with approximation ability for coping with unknown disturbances and unknown system dynamics to controller design. An adaptive sliding-mode controller is then designed in the framework of backstepping, and a first-order low-pass filter may be introduced to handle the problem of derivative explosion associated with traditional backstopping control. A rapid terminal sliding-mode surface may be adopted to further improve tracking accuracy and obtain better performance. Finally an adaptive sliding-mode control method may be proposed in the case of merging the rapid terminal sliding-mode surface, the first-order low-pass filter and the RBF neural network.
