Patent number: 11500005Abstract: Methods, systems, and apparatus, including computer programs stored on a computer-readable storage medium, for obtaining a reference phase signal that is synchronized with an alternating current (AC) phase of a multi-phase electrical power distribution system. The apparatus obtains output signals from sensors, each output signal representative of an electromagnetic emission detected by a respective sensor. The apparatus identifies, based on comparing respective phases of the output signals to the reference phase signal, a particular AC phase of the multi-phase electrical power distribution system associated with a source of the emissions. The apparatus provides an indication of the particular AC phase to a user.Type: GrantFiled: April 29, 2021Date of Patent: November 15, 2022Assignee: X Development LLCInventors: Leo Francis Casey, Siyuan Xin, Peter Evans, Shuyu Wang, Raymond Daly, C.

Patent number: 4819722Abstract: The invention relates to conventional metal well screens which have a screen wire wrapped about a plurality of internal support rods to define the screen slots, and particularly to a novel plastic end fitting made of a thermoplastic material which is mechanically attached to the well screen by means of a plurality of circumferentially spaced tongues which engage the inside surface of the screen wires and have a portion of their outer surface positioned within the screen slots. Slots formed in the end fitting between the tongue portions contain the support rods. A method of attaching a thermoplastic fitting made of a material such as polypropylene is also disclosed and includes the steps of heating the tongue portions so that a portion of their outer surface is melted and then is forced radially outwardly into the screen slots, and preferably slightly beyond them, by a pressure applying device such as a tapered wedge tooling arrangement.Type: GrantFiled: January 19, 1988Date of Patent: April 11, 1989Assignee: Johnson Filtration Systems, Inc.Inventor: Raymond A.
