Abstract: A tape measure holder device is provided, having the ability to be positioned on a belt of a user for easy access or replacement thereof. The device comprises a base plate, a horizontal attachment shelf, two guide mounts and a belt attachment means. The belt attachment means comprises two vertical clips, or alternatively a loop adapted to fit a user belt therethrough comprising a rigid loop or a larger, flexible loop for use with a carpenter's belt. A tape measure is secured using its attachment clip, which slides over the horizontal attachment shelf between the two opposing guide mounts, securing the clip between the shelf and the base plate. To remove the tape measure, a user slides the tape measure vertically from the horizontal shelf. An offset is provided by the attachment shelf that facilitates easy removal and replacement of the tape measure during operation.

Abstract: A fault-tolerant position feedback filter may be used in an actuation control system to limit the authority of a first position signal, should the first position signal become erroneous, and thereby prevent a postulated runaway condition of an acuator. The filter includes a difference function, a limited integrator, and a summer. The difference function supplies a first position error signal representative of a mathematical difference between a first position signal and a combined position signal. The limited integrator supplies an integrated position error signal that is limited in magnitude to a predetermined limit. The summer supplies the combined position error signal that is representative of a mathematical sum of the integrated position error signal and the second position signal.

The filter includes a difference function, a limited integrator, and a summer The difference function is coupled to receive a first position signal and a combined position error signal and is operable to supply a first position error signal representative of a mathematical difference between the first position signal and the combined position signal. The limited integrator is coupled to receive the first position error signal and operable to supply an integrated position error signal that is limited in magnitude to a predetermined limit. The summer is coupled to receive the integrated position error signal and a second position signal and is operable to supply the combined position error signal.

Abstract: An apparatus for dispensing a liquid onto a vehicle generally consisting of an inverted, U-shape support frame providing a space for receiving a vehicle therethrough; at least one liquid dispensing device supported on said frame, having a shaft provided with a longitudinally disposed first passageway section communicable at one end thereof with a source of liquid under pressure, a second passageway section communicating with the first passage section and disposed at an angle relative thereto and a plurality of third passageway sections communicating with the second passageway section, spaced circumferentially and each disposed at an angle relative to a longitudinal centerline of the second passageway; and means for rotating the shaft about a longitudinal centerline thereof.
