Abstract: An improved work machine of the eccentric piston type which may be employed to translate force of pressurized fluid into rotary shaft motion in an external combustion type engine system, as a pump for pumping fluids in a fluid handling system, and as a fluid actuated motor. The work machine comprises a housing having an internal compartment with a peripheral lobe. An inner body is mounted for non-rotational orbital movement in the housing. The inner body housing, and a movable wall member located in a peripheral recess of the inner body form variable-volume fluid intake and discharge chambers in the housing compartment during orbital movement of the inner body. Pressurized fluid supplied to the fluid intake chamber of the housing imparts non-rotational orbital movement of the inner body in the housing and corresponding rotational motion to an output shaft on which the inner body is eccentrically mounted.

Abstract: An improved surface wind batcher and method of collecting material in roll form while maintaining positional stability of the roll during its rotation comprising a pair of rotatably driven parallel side-by-side spaced support rollers which support and peripherally drive a roll of web material fed thereto in continuous length form. The rollers are mounted in movable bearings operated by pneumatic pistons which are automatically actuated during roller and roll rotation to increase the distance between the support rollers and thereby ensure positional stability of the rotating roll on the support rollers. Upon completion of roll formation, the support rollers are actuated to automatically doff the roll of material therefrom and return them to initial closely spaced position for formation of another roll.

Abstract: A device for engagement with a moving web to remove curl, fold or crease from an edge thereof. Opposite banks of elongated stationary fins are angularly disposed with respect to the direction of movement of the web and are spaced apart to define a predetermined web passageway therethrough. The edge of the traveling web passes between the banks of fins and cooperative forces produced by the opposing banks of the elongated angularly disposed fins remove curl from the edge of the web as well as removing folds and creases. In a preferred embodiment, the elongated fins have opposite taper at leading and trailing ends to permit proper feeding of a web therebetween and to permit location of the device in close proximity to adjacent web handling equipment. In another preferred embodiment, the two banks of elongated fins are operatively associated under spring tension, whereby adjustment may be made between banks of fins while damage to a web passing therethrough or to the device is substantially alleviated.

Abstract: An improved coating composition, coated reinforcement fabrics, reinforced rubber-based substrate products, and methods of manufacture thereof are disclosed. The coating composition comprises a carboxylated neoprene latex containing an aqueous dispersion of a copolymer of chloroprene and methacrylic acid, polyvinyl chloride as a colloidal stabilizer, and a high boiling oil derived largely from aromatic petroleum feedstocks through a distillation range of between about 195.degree. C. through 325.degree. C. The composition is highly stable, has a long shelf life, and is particularly suited for precoating textile reinforcement fabrics to provide a highly tacky uncured coating surface thereon having exceptionally long high tack in uncured, or green, state. The fabric is employed as a reinforcement layer or cover in rubber-based industrial products, such as power transmission belts, and may be applied in intimate physical adhesion therewith for subsequent vulcanization bonding thereto, as in a vulcanizing mold.

Abstract: Method and apparatus for handling textile yarn strands in which textile yarn strands subjected to a heat treating operation are continuously directed from the heat treating apparatus by a stream of air through an oscillating tube onto a moving conveyor belt to deposit and accumulate the yarn strand thereon in a substantially tensionless condition for cooling. The yarn strand is removed from the accumulated yarn on the belt surface in a direction generally parallel to the surface and to the direction of movement of the accumulated yarn thereon to minimize tangling of the yarn, and the strand is subjected to a cooling air stream directed oppositely to its direction of movement to detangle the same prior to collection on a package. The speed of yarn package take up is controlled by means of a photoelectric sensing device located above the conveyor belt to sense the amount of yarn accumulated on the belt, and to ensure that a predetermined amount of yarn is maintained on the belt during the cooling operation.
