Abstract: A member oscillates on a face and another member pivots on a bed of the first member. Passages are provided through the members to lead a lubrication fluid under pressure into a fluid pocket between the mentioned face and one of the members. The fluid pressure in the pocket carries a major portion of the load of one of the members on the face. The oscillation of the members has one stroke under higher load and one under less load. The pivotal movement of the other member controls the flow of fluid through the passages to provide high pressure in the fluid pocket at the stroke under higher load and lower pressure in the pocket at the stroke under less load. The arrangement is especially suitable to be provided on pistons and piston shoes of radial piston machines. But it can also serve to carry load on other members of machines or vehicles, wherein at least two movements are taking place and a source of supply of fluid under pressure is available.

Abstract: A radical flow mechanism is provided having a symmetric housing assembly defining a hollow rotor chamber. A symmetric shaft and rotor assembly is supported for rotation in the rotor chamber. A plurality of radial flow paths are defined by the rotor and the housing assembly. The assembled module may be powered by a pressurized motive fluid that flows radially inward to rotate the rotor. Alternatively, the rotor may be driven by an external power source so that a working fluid increases in potential energy as it moves centrifugally outward. The assembled module is symmetric about the rotor member so that the rotor can be orientated for either direction of rotation and so that power takeoff or power connection can be to either side of the module. Also, the module is constructed so that the seals are located at an interface having a low pressure differential and the bearings are located adjacent an area encouraging heat dissipation.

Abstract: An axial fan is disclosed that includes a hub supported for rotation around the longitudinal axis of the fan, a plurality of impeller blades attached to the hub and extending radially from the axis of rotation, a shroud assembly including a band encircling the blades and spaced from the tips of the blades a sufficient distance to provide ample clearance to avoid contact between the blades and the band during shipment and operation of the fan, the shroud further including an orifice positioned upstream of the blades for preventing air from flowing between the orifice and the band, the orifice having a downstream end located adjacent to but spaced from the impeller blades and having a diameter such that the impeller blades extend outwardly from the hub beyond the orifice so that the flow of air over the tips of the impeller blades is substantially reduced, which increases the efficiency of the fan.

Abstract: Partially overlapping sheets of a scalloped stream of sheets are delivered to spaced apart intermediate portions of two elastic bands. One end portion of each band is connected to a second core on which the bands are convoluted over each other so that their convolutions alternate, and the other end portions of the bands are connected to axially spaced apart portions of a first core which gathers a roll of sheets when it is driven in a direction to collect the bands while the sheets of the stream are delivered to the bands between the two cores. The cores are coaxial with each other and are mounted in a frame which further supports several sets of pulleys serving to move the two bands apart in the axial direction of the first core between the first and second cores so that the convolutions of the two bands on the first core overlie axially-spaced apart portions of convoluted paper sheets.

Abstract: An apparatus for assembling and depositing book signatures by means of signature-receiving compartments which are movable independently of one another and independnetly of a common rotary hub on which the compartments are carried to provide improved signature receiving, stacking, aligning and discharge, among other benefits.

Abstract: The present provides a new and improved apparatus for verifying the operation of a signature hopper of a collator. The hopper includes a rotary drum for transporting a signature from a storage bin to a feed location on a raceway having a moving conveyor. Two reflectors are secured to the drum. A first, miss reflector, is located so as to be covered by a signature during a normal feed operation. A second, miss verify reflector, is located so as not to be covered by a signature during a normal feed operation. An optical sensor directs a beam of light toward the drum and monitors for light reflected by the reflectors. A controller determines when the sensor should receive a reflected beam from the miss verify reflector. A warning signal is generated if no light is reflected from the miss verify reflector when it is expected.

Abstract: A hydraulic booster in which the booster piston return spring is formed as a tubular conduit to conduct hydraulic supply pressure to a closed center valve. Upon actuation, the valve opens to permit supply pressure to flow into the power chamber and by valving action controls the exhaust of pressure from the power chamber so as to establish the desired actuating pressure therein. The tubular conduit forming the power piston return spring and transporting the supply pressure to the closed center valve permits a shorter overall axial length of the hydraulic booster by accommodating the movement of the supply pressure chamber at the closed center valve. It also permits less charged supply pressure leakage by accommodating a better pressure seal arrangement.
