Abstract: Disclosed are metal cleaning formulations and methods of use. A formulation of the present teachings comprises one or more furoate esters such as ethyl 5-methyl-2-furoate and methyl 5-methyl-2-furoate. The formulations further comprise a base oil, which can be, for example, a naphthenic oil, a synthetic oil or a combination thereof. In some embodiments, a formulation can further comprise a metal protection additive and a lubrication additive. A variety of base oils, metal protection additives, and lubrication additives are suitable for use in the present teachings. Formulations of the present teachings are especially useful for the cleaning of metal products such as firearms. The cleaning power of a formulation of the instant teachings can exceed that required for US Military Specifications.

Abstract: Geo-tags embedded in user created media files are used to maintain a location history record for a mobile computing device. At least one gap in the location history record for the mobile computing device is identified. The mobile computing device is scanned to identify accessible media files in at least one specific format created during the gap. Such specific media formats can comprise photographs, videos, audio, etc. Identified media files created during the gap are scanned for embedded geo-tags. The location history record for the mobile computing device is updated with data points comprising locations of the mobile computing device as identified by geo-tags embedded in specific identified media files (e.g., locations of the device when specific digital photographs were taken), and the times at which the specific identified media files were created (e.g., the times at which specific digital photographs were taken).

Abstract: A trip indicator is for a circuit breaker having a housing including first and second openings, separable contacts and an operating mechanism having an operating handle for opening and closing the separable contacts. The trip indicator includes a trip indicating member with a first end having a trip indicia and a second end with first and second projections. The first projection is engaged by a cradle of the operating mechanism when the separable contacts are not tripped, in order to prevent the trip indicia from being viewable at the second opening of housing. The first projection is disengaged and released when the separable contacts trip, causing the trip indicating member to move in order that the trip indicia is viewable at the second opening. A locking feature in which the second projection engages and locks operating handle, is also disclosed.

Abstract: A removable universal terminal assembly has a molded housing that clips onto an electric power switch and two terminal members that can be alternatively installed in the molded housing to provide either a quick connect termination or a binding post termination.

Abstract: A terminal assembly can be alternatively used to make either a pressure plate or screw type connection for connecting stranded wire or solid wire, respectively, to a power conductor of electric power apparatus such as a circuit breaker. An electrically insulative barrier has an elongated member with a lateral extension at one end having a recess that captures the head of the screw of a terminal collar for the pressure plate connection. As the screw is tightened, the collar is drawn toward the power conductor to clamp the stranded wire between the collar and one side of the power conductor. With the elongated member turned end for end, the screw is free to clamp the solid wire against the other side of the power conductor. Pairs of integral compliant latches on the elongated member accommodate quick conversion between the two types of connections.
