Abstract: A circuit comprises an inductor, a load, and a controllable switching device arranged in either a first configuration: switchable between the load being bypassed and the inductor energised, and current flowing through the load, and the inductor discharging energy into the load; or, a second configuration: switchable between current being permitted to flow through the load, inductor and controllable switching device in series, energising the inductor, and the current flowing through the load, and the inductor discharging energy into the load. The circuit further comprises control means for controlling the switching device, a load current sensing resistor connected in series with the load, and a demand signal input. Monitoring means is arranged to monitor the demand signal and the voltages across the sense resistors, and generate a monitor signal. The control means is arranged to receive the monitor signal and to switch the switching device in response the monitor signal exceeding a predetermined threshold.

Abstract: An artificial fishing lure, composed of a plastic injection molded body, having hangers for hooks. a line tie point, a lip for diving, a rib at each side for controlling water flow. an elliptical body shape, a groove molded into each side of the body beginning at the nose and continuing to a point just aft of the nose, where a fin assembly is mounted. Water is passed along the groove, through a channel in the rib at the side of the body, where it is forced outward causing an increase of pressure on the underside of the fin, resulting in a lifelike motion of the fin.

Abstract: An artificial fishing lure, composed of a plastic injection molded body, having hangers for hooks, a bill or lip, a cylindrical body, including a groove encompassing the body just aft of the head, a channel molded into each side beginning on the bill or lip continuing through and to a point aft of the groove, wherein a molded plastic ring and fin assembly are mounted. Water is passed along the channels at each side of the body when the lure is moved, causing an increase in pressure on the underside of the fin assembly, resulting in a lifelike motion of the fin.

Abstract: All or part of bisphenol-A process mother liquor recycle stream is contacted with acidic cation exchange resin to remove color bodies. The acidic cation exchange resin is periodically washed and reactivated after use by a mixed phenol/water wash.
