Abstract: A fluid powered motor-generator apparatus includes a generator having a power output and a mechanically driven input. A generally streamlined motor body is rotatably mounted to drive the generator input and includes a plurality of radially extending generally V-shaped fins mounted on an outside surface thereof. The fins are mounted on brackets above an outer surface of the motor body and have a convex pointed side facing in the direction of rotation and a concave open side facing in a direction opposite to the direction of rotation. Thus, the action of a stream of fluid on the fins tends to rotate the motor body and drive the generator. If the motor-generator apparatus is mounted in water, the generator can be enclosed in another streamlined body which is anchored to the bed of the body of water.

Abstract: A device for forcefully removing husks from coconuts provided with a pair of hingedly connected wedge blades adapted to be inserted into the coconut husk. One blade is stationary and the other blade has a handle to enable it to be rocked for prying the husk away from the seed. Two or more operations are required for removing the entire husk. The so-called stationary blade is fixed to a vertically movable cross bar, the ends of which slide on spaced rods forming part of a frame. The frame is intended to be mounted upright on a support, such as a post.

Abstract: A transfer member for transferring ink, paint, and other like vehicles containing organic solvents and a process for its preparation are disclosed, characterized in that the member comprises a polymerized, cross-linked polyurethane, particulate silica, and a bonding amount of a reacted silane. Preferably, the cross-linked polyurethane is prepared by interreacting an organopolyisocyanate with a mixture of hydroxyl-containing organic compounds, such as an organodiol, an organotriol, and optionally, an organopolyol containing more than three hydroxyl groups.

Abstract: Molding apparatus for forming a roller, such as a printing roller, and the resulting product are disclosed in which such apparatus includes an elastomeric sleeve and a core, the sleeve telescopically receiving the core and defining therebetween a casting area to receive a settable adhesive. One of the sleeve and core has axially extending grooves on a side facing the other to facilitate substantially even distribution of the liquid adhesive between it and the other member, whereby upon receipt and setting of the adhesive, the sleeve, adhesive and core define an integrated roller of substantially uniformly distributed balance and weight. Preferably, the set adhesive has substantially the same density as the elastomeric sleeve. Optionally, two adhesives may be used, as concentric tubular coatings, one adhesive to coat the core and a second adhesive used in greater amount to coat the sleeve and fill the casting area.
