  • Patent number: 4186069
    Abstract: A photopolymerizable system is provided as a latex system that is an oil-in-water polymer emulsion including particulates of water-insoluble polymers in combination with a water-soluble or water-dispersible, light-sensitive polymer having multiple light-sensitive moieties. Prior to coating onto a substrate, the system is a three-phase precursor emulsion of the emulsion particulates, the water phase, and the light-sensitive polymer. After coating, the bulk of the water phase is evaporated off, leaving a two-phase system of the emulsion particulates surrounded by the light-sensitive polymer. When selected areas are subjected to actinic radiation, a water-insoluble matrix is formed, the matrix containing cross-linked light-sensitive polymer having dispersed therethrough and/or included therein the water-insoluble polymer particulates, thus forming oleophilic image areas.

  • Patent number: 4184432
    Abstract: A lock mechanism for a hopper door is provided which is especially suitable for use on railway hopper cars having hinged double doors. Included in the lock mechanism is a hook which is mounted on an outside hopper sheet and which is pivotable for engaging extensions of a spreader bar joining the double doors. The hook, being mounted through a slot therein, in addition to being pivotal is also slidable through a limited slaping path that is generally parallel to the floor of the hopper, such slidable action enabling the doors to be held at either a "catch" position or a fully closed position. The lock mechanism positively positions the doors with opening and closing operations. An especially secure lock, one which maintains door closure even when the railway car is rotated is attained when a latch having a spring-like projection holds each hook and thus the hopper doors in their fully closed positions.

  • Patent number: 4171493
    Abstract: A linear induction motor includes one ferromagnetic member thereof which is movably resiliently mounted in the motor frame so as to move toward the stator in the motor whenever current is applied thereto. A portion of the armature in the motor extends between the resiliently movable member and the motor frame. When the motor is energized the armature is free to move between the ferromagnetic member and stator. When the motor is de-energized, the resiliently movable member is biased toward the motor frame and sandwiches the armature between the member and the frame so as to prevent the movement thereof. Reactivating the motor then attracts the movable member toward the stator and frees the armature.
