Abstract: For use with a printing apparatus that has a plurality of printing rollers, at least one ink fountain, and at least one inking blade that is positioned adjacent one of the inking rollers, the inking blade having a plurality of adjusting keys thereon, an ink control system connected to the inking blade for controlling the adjustment the adjusting keys. The ink control system comprises a system unit for controlling the overall operation of the ink control system, an operator console for inputting commands which control the adjustment of the adjusting keys, a servo powder unit for controlling the adjustment of the adjusting keys, and a plurality of servo modules each of which performs the adjustment of one of the adjusting keys by actuating the one adjusting key.

Abstract: An automatic guidance device for a self-powered cargo-moving vehicle is bolted directly over the steering column of the vehicle and is operated by a vehicle-borne sensor which follows a magnetic wire path, the guidance system having an automatic, sensor-directed mode, a manually operated power steering mode, and a manual override mode in which the guidance device is effectively disconnected and steering is undertaken by a direct mechanical linkage with the vehicle steering column.

Abstract: A power steering device for a self-powered cargo-moving vehicle has a detented steering wheel which can be shifted by the operator to select either a manually operated, power steering mode, a manual override mode in which the guidance device is effectively disconnected and steering is undertaken by a direct mechanical linkage with the vehicle steering column, and, in one embodiment, an automatic, sensor-directed mode in which the vehicle is automatically guided to follow a magnetic wire path.

Abstract: A novel paint can holder or hanger comprising a bar having a vertical body portion with a furcated lower end defining an inverted V-shaped paint can lip-receiving slot and having an inner leg adapted to extend into the open end of the can and an outer leg overlapping the outer side of the can. The inner and outer legs have opposing notches on their inner edges for receiving the inner and outer edges of the lip. The vertical body portion has on its outer side a bail-entrapping notch arrangement which serves as a fulcrum for the holder when the holder is lifted by handle at the upper end of the body portion, the handle extending to the axial center line of the can. A flexible tether is secured to the handle and is adapted to be looped over a rung of a ladder or the like.
