Abstract: A sorter-finisher system having a sorting unit comprising plural number of inclined bins arranged vertically at specified intervals and a transport unit for transporting bunches of sheets distributed among the bins to a sheet binding unit. When the sheets have been distributed among the bins, the bins move to a sheet receiving opening of the transport unit one by one. The bunches of the sheets in the bins are transported to the binding unit through the sheet receiving opening for binding. The angle of inclination of each bin at the position opposite to said sheet receiving opening is set larger than that of the bin at the position for the distribution of the sheets. In order to shift each bin from the position for the distribution of the sheets to the position where the sheet receiving opening is located, for example, a cam with a spiral groove designed to engage with a trunnion provided to each of the bins is used.

Abstract: A flow fence for a turbo fan jet engine, as taught by Stein et al. in U.S. Pat. No. 3,841,790, is modified by the provision of serrations about its internal circumference. Thus, when the modified flow fence is inserted into or removed from the flow field, a more gradual transition occurs in the flow thereby improving surge margins.

Abstract: A method and an apparatus for treating high-consistency fiber suspension are especially suitable for short distance conveyances of thick fiber suspensions (consistency more than 15%) in pulp and paper industry, for example for discharge of mass towers either with or without any actual pump. The treatment of fiber suspension with a consistency more than 15% is not possible with the known technique without a displacement type of pump, which is expensive and easy to break. Additionally, in discharging of the mass tower, drop leg, etc., fiber suspension causes trouble by arching in the container in such a way that it forms an open chamber around the pump located at the bottom of the container which chamber is slowly filled by fiber suspension. The problems are solved or minimized by arranging a feed apparatus (31) in the pump chamber, which feeds fiber suspension to a fluidizing rotor (21), for fluidizing the fiber suspension, whereafter the suspension flows onwards.

Abstract: An impeller pump including a housing defining a seal cavity having a shaft rotatably mounted therein, and an expeller to pump fluid from the seal cavity. A dynamic seal provides a fluid tight seal between the housing and the shaft. The seal comprises an axially movable primary seal ring which rotates with the shaft and a mating stationary seal ring, both rings disposed annularly of the shaft and each defining a generally radial sealing face adapted to seal against the other. A biasing device urges the primary seal ring into sealing engagement with the mating seal ring. The radial face of the mating seal ring defines a plurality of spiral grooves and a sealing dam area which is at the periphery of the ring exposed to high pressure. When the pump is not operating, the seal ring faces contact one another and the dam provides a seal against the opposing face.

Abstract: A dual hydraulic motor system where motor wobblers are mechanically linked and the motor outputs are torque summed, is controlled by a three position dual valve assembly. Each valve assembly is controlled by pilot pistons that are mechanically linked to provide three functions, one being normal operation, a second where one motor must be shut-off and its load on the system is minimized and the third where both motors are shut-off and significant drag is then provided. These functions are implemented by a separate spool in each valve which has three independent stable positions.

A valve sleeve is slidably inserted in the power piston and is urged rearwardly of the power piston by a spring, and a cam portion provided in the valve sleeve is employed to open and close the supply valve.
