Abstract: A hydraulic impact device in which a hammer member having a piston portion is reciprocally disposed in a cylinder, a reciprocating sleeve valve is disposed within the cylinder and surrounds the hammer member. The sleeve valve has a first peripheral seal with an upper portion of the cylinder and a second peripheral seal with the lower portion of the cylinder so that an annular cavity is formed between the first and the second peripheral seals. The bottom portion of the sleeve valve forms a single seal with the upper portion of the piston section. A pressure relief valve is situated between the inlet to said annular cavity and an annular cavity below the piston portion to insure that the pressure in said annular cavity is greater than the pressure in the cavity below the piston portion and the sleeve valve thus effecting a sealing force between the sleeve valve and the upper face of the piston portion. An energy storage means is provided for receiving energy from said ram member during its upward stroke. The upper and lower sealing portions of said sleeve valve are axially spaced such that when said lower sealing portion seals a fluid inlet port, the upper sealing portion opens a fluid outlet port thereby reducing the pressure in said annular cavity by interrupting a fluid communication between the inlet port and said annular cavity and establishing fluid communication between the outlet port and said annular cavity.

Abstract: A paper winder assembly of the type in which a rider roll is positioned to bear against a roll on which the traveling paper web is being wound. The rider roll position is controlled by hydraulically actuated lifting means which vary the pressure at which the rider roll bears against the paper roll. In accordance with the present invention, there is included a pressure modulating valve which converts air pressure signals to hydraulic signals which operate the hydraulically actuated lifting means. The valve includes a pair of flexible diaphragms therein with means to introduce air under pressure on opposite sides of the two diaphragms depending upon whether the rider roll is to be raised or lowered. The valve has a spool actuator therein which is movable in response to the movement of either of the diaphragms. A spring means biases the spool downward and establishes fluid communication between an inlet port and an outlet port for transmitting hydraulic fluid to the hydraulically actuated lifting means. A feedback is provided in the valve body so that fluid pressure acts on the spool in opposition to the spring biasing force and eventually establishes an equilibrium position. When the back pressure of the hydraulic lifting system is sufficiently high, the spool is positioned in valve closing relationship, and excess hydraulic fluid is passed to a drain.

Abstract: A web spreading and guiding device to maintain a running paper sheet making foraminous web comprising a wire or pick-up felt transversely taut and straight running in a papermaking machine, has a pair of free running pneumatic tires having their treads in nipping relation to one another to engage a margin of the web in the nip, the tires being carried by an arm which is pivotally biased to effect transverse web stretching bias of the tires on the web margin running through the nip. Generally one of the devices will be mounted to act on one margin of the web and another of the devices on the opposite margin of the web and the devices being cooperatively biased to stretch the web in opposite directions. Means are provided to control the tire bias for correcting any deviations of the web from a straight running path.
