Abstract: An improved apparatus for inspecting and video taping pipelines is provided. A tubular vessel accommodates a video camera. A plurality of scuba lights are adjustably mounted to the periphery of the tubular housing at the front end of the apparatus. A dual-section guide leg is provided which has limited upward and downward movement and limited forward and rearward movement. An elastic member controls the upward/downward and forward/rearward movement of the guide leg to provide a shock absorber system. The guide leg engages the top inside surface of the pipeline as the apparatus is carried down the pipeline by the current. The angle of inclination of the apparatus may be controlled with weights, foam and the position of the guide leg.

Abstract: Cleaning of water intake and outfall pipe passage wall incrustation is effected by propelling an incrustation dislodging device along the wall while running fluid through the pipe to flush the dislodged incrustation, which may be collected for disposition at the pipe discharge. A preferred form of the cleaning device comprises a circular stiff wire brush assembly through which the flushing fluid can flow at a greater speed than the propulsion speed of the device. A sea anchor may be used to run propulsion line for the device through the pipe passage. Before effecting operation of the device, a camcorder may be run along the incrusted passage wall for determining the nature of the incrustation.

Abstract: A plate gripper mechanism attachable to a robotic arm structure for transferring a sheet metal plate to or from a work station, e.g., stamping press, welding machine, milling machine, rivet machine, etc. The gripper mechanism utilizes a small commercially available fluid motor actuator in direct drive connection with a rotary shaft in the gripper mechanism, whereby the mechanism is relatively small and light. The mechanism is preferably constructed from bar stock, plate and tube stock; no special castings, stampings or forgings are used in preferred practice of the invention.

Abstract: A quick disconnect device having a locking feature for securing the quick disconnect device in a lock position is provided for connecting tooling attachments to the boom of an electromechanical feeder used with pick and place operations. The locking action utilizes a cam and follower arrangement and is provided by a detent in a lock position of the cam contour. The detent retains the cam follower in the lock position and prevents the cam follower from becoming unintentionally released, preventing the tooling attachment from becoming loose or disconnected from the boom.

Abstract: An indoor baseball game includes apparatus comprising a rectangular enclosure having netting walls and roof, a playing surface of synthetic grass or the like within the enclosure has a minature baseball diamond marked thereon and a bonus "home run" area is defined on the wall of the enclosure behind second base, a "running line" is marked on the diamond 11.5 meters past home, first and second bases, and must be reached by a runner to avoid being "out", before the baseman on the proceeding base contacts the base with the ball in hand. Various parts of the walls of the enclosure are defined as providing bonus bases when the batter hits the ball so as to contact such parts. Bonus bases are in addition to those achieved by running and to which safe passage is ensured. A complete set of rules for playing the game are set forth.
