  • High frequency-high flow servo valve
    Patent number: 4199007
    Abstract: A servo valve controls the rate and direction of flow of a hydraulic fluid from a fluid power system to impart reciprocating motion to the piston of a hydraulically driven motor. An outer sleeve member of the servo valve has entry and exit ports connected to the source of fluid power and motor control ports connected to the hydraulically driven motor. A slider member is positioned within a cylindrical opening through the sleeve member and includes fluid chambers within the slider for alternating the direction of fluid flowing to the hydraulically driven motor by rotating the slider member. The rate of fluid flow is controlled by the lateral movement of the slider within the sleeve member.

  • Torque controlling set screw for use with the cable of solderless connectors, or the like
    Patent number: 4199216
    Abstract: In certain applications, such as solderless cable connectors, a set screw is used to provide the connection between two or more current conductors. The set screw should be tightened to no more than a predetermined tightening torque. This is automatically accomplished by providing a section along the length of the set screw that is weakened to a predetermined extent, which causes the screw to break at the section upon attainment of the predetermined tightening torque. Both portions of the separated screw include means for being engaged for tightening or loosening the screw.

  • Method for preparation of lithographic printing plate having addition polymerized areas and binder areas
    Patent number: 4198236
    Abstract: A lithographic printing plate is prepared from a layer of a photopolymerizable composition comprising an oleophilic macromolecular organic binder and a leachable hydrophilic ethylenically unsaturated compound by exposing the layer and then leaching the compound from the unexposed areas by treating with a suitable developing solvent, preferably water, producing an oleophilic surface. A similar plate may be prepared from a composition containing a hydrophilic binder and oleophilic leachable compound by imagewise exposure and solvent leaching producing an oleophilic surface in exposed areas and a hydrophilic surface in unexposed areas.

  • Movable amusement toy
    Patent number: 4198068
    Abstract: A movable amusement toy in the form of a vehicle adapted for pulling, and which is also provided with a seat for a user to push the vehicle with his legs while sitting on the same. The vehicle could also be adapted for pedalling action. A "popper" or ejecting mechanism provides an action or ejecting or "popping" balls or similar objects into a chamber formed by a transparent cover on the toy vehicle during movement. The chamber transparent cover is highly visible to a child as the child rides or pulls the toy. The ejecting mechanism includes a head which is capable of simultaneously popping several of the balls or similar objects from a trough formed beneath the housing and is actuable through mechanical connection to the wheels of the vehicle so that rotation of the wheels during movement of the toy will actuate the mechanism to pop the various balls or similar objects.

  • Game device with release ramp and scoring recesses
    Patent number: 4198050
    Abstract: A competitive game device which comprises a frame having a rippled playing surface. The rippled surface is formed by a plurality of transversely extending spaced apart recesses separated by arcuately shaped transversely extending ridge portions. The various recesses are assigned scoring values and certain of the recesses also have higher scoring values than other recesses. Each player may have a plurality of balls bearing his indicia. For example, the balls of each player may be a different color. A ramp leads downwardly to the first recess and the players take turns releasing balls down the ramp and onto the rippled playing surface. In a preferred form, the values of successive recesses initially increase; however, if a player's ball goes past the highest value recess, he will get a lower score, by virtue of the ball landing in a lower scoring recess or other area such as a gutter.
