Abstract: A device for scooping up and containing dog excreta for later removal comprising two engaging parts one part of which serves as a scoop for use in scraping and excreta into the hollow interior of the other part. A handle comprising two parts is provided which parts individually serve to each support a different one of the parts and when the parts are moved into engagement interlock to form a single handle for supporting the assembled device.

Abstract: An apparatus for automatically detecting angular motion of a test object, such as a clutch output, utilizing photoelectric devices in combination with helically apertured light shutters, the electric outputs of the photoelectric devices being interpreted by analog logic. Provision is made for a predetermined number of warm-up rotations of the test object to assure normal working conditions, for a predetermined reference threshold of detected motion, for controlled sequencing of the test object for testing for motion at various predetermined angular positions, and for determining malfunctioning of the test sequencing control.
