Abstract: A shower pipe assembly useable in the papermaking process includes a shower pipe, including structure for oscillating the shower pipe along an axial path and a base. Oscillating support structure couple the base to the shower pipe and supports the shower pipe wherein oscillation of the shower pipe is constrained along a straight line path. The assembly further includes a first arm rotatable about a first axis being stationary relative to the base during rotation of the first arm. A second arm is rotatable about a second axis extending through the first arm such that the distance between the first axis and second axis remains constant. The second arm should be of a length relative to the distance between the first and second axis to produce a straight line motion at a particular location of the second arm upon rotation of the second arm about the second axis a constant distance per degree of rotation of the first arm about the first axis.

Abstract: A straight line motion producing apparatus useable in the papermaking process includes a base, a first arm rotatable about a first axis being stationary relative to the base during rotation of the first arm. A second arm is rotatable about a second axis extending through the first arm such that the distance between the first axis and second axis remains constant. The second arm should be of a length relative to the distance between the first and second axis to produce a straight line motion at a particular location of the second arm upon rotation of the second arm about the second axis a constant distance per degree of rotation of the first arm about the first axis. The apparatus further includes a mechanism for rotating the second arm about the second axis a constant distance per degree of rotation of the first arm about the first axis to produce a straight line motion at a particular location on the second arm.

Abstract: A suction pipe assembly for dewatering a web in a papermaking machine includes a rotating pipe supporting suction cover and attached to a frame by a bearing sleeve. Support members extend form the bearing sleeve to the pipe without obstructing the flow of air through the pipe.

Abstract: A tubular or cylindrical filter structure consists of a plurality of ring-shaped elements disposed in stacked relation by connecting rods and supporting a filtering media. The filtering media is disposed inside or outside the ring-shaped elements, depending on the direction of fluid flow therethrough. The ring-shaped elements protect the filtering media from tensile or compressive forces generated by the fluid flow, and at the same time present an open structure.

Abstract: A vacuum controller for controlling the vacuum at a controlled vacuum which includes a balanced piston arrangement coupled to a valve piston reciprocal with respet to a valve seat positioned between the controlled vacuum and a high header or source vacuum. A throttling of the header vacuum takes place across the space between the valve piston and valve seat and is such that the header vacuum does not influence the movement of the valve piston.

Abstract: A motorized shower head mechanism is disclosed in which a housing is provided with a track and a trolley, and a motor mounted on the trolley. The trolley is moved along the track by the motor and a shower head which extends through the housing is carried along by the trolley.

Abstract: An electro-mechanical oscillator has a DC motor with an output shaft coupled to a ball screw. A ball nut riding on the ball screw is coupled to an output sleeve which moves linearly with the ball nut. When the ball nut reaches one of two extreme positions its direction of movement is reversed by reversing the polarity of the voltage supplied to the motor. A control board is provided for monitoring the position of the ball nut, for reversing the motor and for controlling the speed of the motion.
