    摘要： A vibration system for concrete pipe making machines which system utilizes a precisely manufactured inner mold core that contains mounting surfaces for two coupling shaft bearings and two electric vibrators. The bearing mounting surfaces are accurately located with respect to the electric vibrator mounting surfaces to allow the mold core to become the vibration structure. Jaw-type coupling hubs are keyed and fixed to each end of a coupling shaft with each electric vibrator also having a jaw-type coupling hub fixed to one end of its eccentric weights. The eccentric weights of both electric vibrators are aligned upon assembly in the core.

    摘要： A press of the kind for the preparation of pellets of cattle feed or other pelletizable material and comprising an annular die having a plurality of radial bores therein, which is mounted on a driving rim for rotation around a stationary support fitted with a number of pressure rollers, each freely rotatable on a stationary shaft and in closely spaced relationship with the interior surface of the die, the arrangement being such that material fed into the interior of the die is forced through the bores therein by the action of said pressure rollers, characterized in that the die and driving rim therefor are provided with complementary circumferential mating male and female frusto-conical surfaces, there being wedge means on one part engagable with ramp means on the other part such that transmission of torque from the driving rim to the die causes said ramp and wedge means to cooperate to bring said mating surfaces into pressurized engagement.

    摘要： An apparatus for producing concrete tubes using a vertical tubular mold with a rotating piston moving upwards axially inside the mold. The piston is operated in such a manner that as the torque required for rotation of the piston decreases owing to a decrease in the supply of concrete, the rate of upward travel of the piston is decreased.

    摘要： Pipes having dense, watertight concrete walls are produced by vibrating a rotating mould suspended on a roller shaft as the mold is being filled, and continuing its rotation without vibration for a short time after the mold is filled. Vibration is attained by ridges or fingers which can be made effective, or not, to vibrate the mold as it is rotating. In one form, fingers on a roller shaft are slidable between ineffective positions and positions where they serially engage a smooth running surface on the mold. In other forms, a mold is movable from a position where it is supported by engagement of a ridged running surface on either the roller shaft or the mold with a cylindrical surface on the other to a position where the cylindrical surface on the mold runs on the roller shaft or on an auxiliary sleeve without vibration.
