Abstract: An on-demand security inspection system is provided for dispatching an investigator to a target dwelling. The investigator (e.g., a police officer) carries a video camera (e.g., a body cam). The inspection system comprises a service management server, a requestor interface, and an investigator interface. The requestor interface is configured to link a user to the service management server in order to specify a checklist. The investigator interface is configured to link a mobile unit (e.g., a vehicle control module or a handheld mobile unit) to the service management server in order to (1) communicate a plurality of checklist prompts to the mobile unit, and (2) return video data from the video camera captured according to the checklist prompts.

Abstract: A method and apparatus for safely controlling fluid flow comprises a safety control valve that automatically stops fluid flow upon a fluid pressure failure, requires two-handed manual operation to open the valve, and the valve being biased to prevent being left in the open position in the absence of fluid pressure. The safety control valve comprises a valve body that coaxially receives therein a slidable spool manually operable in an axial direction between a closed valve position and an open valve position. The valve further comprises a spring and a spring biased coaxial safety piston capable of axial movement along the spool and being pneumatically connected to a fluid supply line. In the absence of fluid pressure, the spring biases a safety piston against a contact surface of the spool so as to bias the spool into the closed position thereby preventing fluid flow through the valve.

Abstract: A portable machine tool includes a bed and a cantilevered ram mounted for movement in a longitudinal direction along the ways thereof. A dovetail slide on a side of the ram movably supports a rotatable spindle unit capable of machining in the transverse direction completely crossways of the bed.

Abstract: A portable lathe device is modular in character and can be employed for flange facing, line boring or other purposes. The spindle carrying the tool means is readily axially adjustable, and the radial feed rate for a facing head tool carrier is infinitely variable and reversable.
