A floating drift apparatus for verifying the inner diameter of tubulars as the tubulars are made up into a tubular string being run into a wellbore. A float section provides buoyancy to float the apparatus in fluid within the bore of a tubular, and a drift section has a drift element with a diameter substantially equal to the tubular inner diameter being verified, which may be the drift diameter. When running a tubular string, the apparatus is inserted into the bore of the tubular string, floating in the fluid. As joints of tubular are made up and run into the wellbore, the tubulars move downhole around the apparatus. Preferably, the floating drift apparatus can be visually detected. If an undersize ID is encountered, the floating drift apparatus will be pushed downhole and no longer visible; the operator can remove the undersize ID tubular from the string.

A locator mechanism for checking dimensions of a component includes a stationary base that has sides that define a pocket that opens upwards. A locator block is disposed in, and moveable in, the pocket. At least one spring biases the locator block toward one of the sides of the stationary base. The locator block carries either a recess or a portion of a pin for engaging, respectively, either a boss or a hole of a component to be checked. The spring biases the locator block, and thus also the component, toward the one side of the stationary base to remove play in positioning of the component.

This present invention relates to a collapsible social distancing device for creating a physical barrier around a wearer of the device. More specifically, the social distancing device is an expandable and collapsible device that can be worn by a wearer on any part of the body. The device preferably provides a six feet radius barrier to indicate the social distancing principle and utilizes a foam construction to prevent any injury or damage to another user bumping into the social distancing device. The device includes a loop opening, a bottom circular barrier and a plurality of connecting arms attached to the loop opening and the bottom circular barrier. The device has mechanical or electronic means to reduce the diameter of the circular barrier and can be carried in a bag when not being used by the wearer for indicating social distance limitations.

A countersink go/no-go gauge is configured to aid a determination of whether a countersink aperture for a rivet is formed to a desired depth. The countersink go/no-go gauge includes a head having a depth defined between a top surface and a bottom surface and a shaft extending from the top surface of the head. The depth of the head is substantially equal to a desired depth of a countersink aperture. In some embodiments the go/no-go gauge includes tolerance features to provide a range for an acceptable countersink depth.
