Publication number: 20230369846Abstract: A passively activated switch system for a high-current coil including a plurality of silicon-controlled rectifiers (SCRs) each electrically coupled to a high-current coil, each SCR electrically coupled in parallel to a fast-acting mechanical switch. A passive voltage detector is responsive to an increase in voltage above a predetermined threshold value indicating a start of an over-current event which closes each of the plurality of SCRs to enable a loop current to create a large electromagnetic force. Each fast-acting switch is responsive to the large electromagnetic force and is configured to close to shunt current from each SCR to prevent damage of at least one of the high-current coils or a system that utilizes a high-current coil, or both.Type: ApplicationFiled: May 11, 2023Publication date: November 16, 2023Inventors: Kathleen Elaine Quinlan, Marcel Pierre Joseph Gaudreau, David B.

Patent number: 4120196Abstract: A production tool wear detector which provides a direct, non-contact measurement of the amount of material removed from a cutting tool due to wear during operation thereof. One or more sensing devices monitor the distance to a selected wearing cutting surface of the tool and the distance to a selected non-wearing reference surface of the tool and such distances are suitably processed by appropriate electronic circuitry so as to provide a signal representing the wear characteristics of such cutting surface, which signal can be appropriately displayed, or otherwise used, to make an operator aware of when the tool has worn to a point below a selected threshold. Such a system permits in situ, continuous monitoring of one or more cutting tools during actual use of the tools in a consistent and accurate fashion at relatively low cost.Type: GrantFiled: March 25, 1977Date of Patent: October 17, 1978Assignee: The Charles Stark Draper Laboratory, Inc.Inventors: Dean Elwyn Hamilton, Marcel Pierre Joseph Gaudreau, Alan Leo Wu
