Abstract: A torque reversing motor control structure and method for a reversible split phase or capacitive start motor including a centrifugally operated start switch and a transformer controlled motor contactor wherein the primary circuit of the transformer is completed through the start switch to prevent reversing the motor contactor without the motor start switch being closed to insure positive reverse of the motor.
Abstract: The invention relates to a positive control especially radial piston motors for hydrostatic motors. Such control, while permitting a large range of rotational speed, is capable of avoiding disturbances in the oil flow occurring during coverage of the edges of includes slide valves and provides optimum smoothness of operation of the hydrostatic drive. It is the object of each slide valve to control the connection between an associated working cylinder and the inflow and outflow of the pressure medium. It is a further object of the slide valve to establish connection between the associated working cylinder and a pressure equalizing conduit, at least during coverage of a first pair of control edges, i.e. in a phase during which the working cylinder is cut off both from the pressure medium intake and from the pressure medium outlet. For this purpose the slide valve is provided with a second pair of control edges.
Abstract: An apparatus for stacking buckets in order which are carried by a conveyor and an apparatus for conveying the stacked buckets in section. The apparatus comprises stanchions disposed vertically on both the side portions of a conveyor, a supporting member capable of moving in the vertical direction along the stanchions which supports a bucket-engaging hook lever and driving means for the supporting member.
Abstract: In an automatic winder wherein a winding package rotates while having surface contact with a transverse drum which is positively rotated, a method and apparatus for stopping the package concurrently with stopping of the drum. The method includes a braking of the drum when brakage of yarn being wound on the package takes place and simultaneous braking of the winding package if the brakage of the yarn takes place after the winding package has reached a predetermined diameter. The structure includes drum brake structure for braking the drum, lever actuated cam structure for sensing the diameter of the winding package, and package brake structure responsive to the diameter sensing structure for stopping the winding package on sensing of yarn brakage and package diameter over a predetermined diameter.
Abstract: A stretcher and litter combination, including a buoyant raft-like structure adapted for use as a rescue or recovery litter, and a buoyant stretcher. The litter has pontoons on either side of an elongated body section. The stretcher is in the form of an elongated board releasably secured to the body section of the litter.
Abstract: A method and apparatus for obtaining packages for dying by twisting and winding processed yarns by a double twister. Between a double twisting spindle and a take-up roller disposed above, there are arranged a winding angle-adjusting device, a feed roller and a traverse device, recited from the side of the spindle. The high yarn tension on the side of the double twister is reduced by using the feed roller having a special structure to obtain a soft wound package.
