The bucket frames have lubricating channels surrounding the pins and sealed against the links.

Abstract: A mold assembly for use in heat forming granular material into a discontinuous cross-sectional board. The mold assembly has an upper and lower frame and two mold halves forming a mold cavity therebetween. The mold halves are coupled to the frame by means of spacer bars. The spacer bars are designed to minimize conduction of heat from the mold to the frame and are positioned over peripheral heaters in the mold to minimize heat gradients within the mold. In addition, the spacer bars minimize heat distortion of the frame members. The interior of the mold is provided with a first array of heaters extending parallel to the longitudinal axis of the mold near the surfaces of the mold halves remote from the mold cavity. A second array of heaters extend through the mold halves parallel to the longitudinal axis of the mold adjacent the surfaces of the mold cavity. The heaters in the first and second array are independently controlled to maintain a constant temperature through the cross-section of the mold.

Abstract: A cooker assembly for use in heat forming a discontinuous cross-section of mold extruded granular material. The cooker assembly has two frames pivotally connected at one end. A pair of hydraulic cylinders are interconnected between the frames for moving the two frames between opened and closed positions. The upper frame has a planar surface for engaging the upper surface of the material as it leaves the mold and is provided with longitudinal heaters for heating the materials as it passes through the cooker assembly. The lower frame has an uneven contoured surface closely approximating the lower surface of the material as it is extruded and heaters extending longitudinally therethrough for heating the material as it passes through the cooker assembly.

Abstract: There is disclosed a system for subaqueous pile driving in which the pile and the hammer are completely submerged. The pile is suspended by at least one cable in such a manner that two cable sections are run in an upward direction from the top of the pile in a parallel manner toward a device located above sea level. The pile is lowered on the cables to the ocean floor, and the pile driving hammer positioned on top of it simultaneously with the pile hammer guided on cable sections. A traverse bore is provided in the pile for passage of the cable, and a temporary support base is provided having slidable frictional contact with the pile for enlarging the base of the pile on the ocean floor.

Abstract: A neutron-irradiation dose monitor is described as comprising a first couple of wires of different nature, soldered to one another by the one end thereof and a second couple of wires of different nature, soldered to one another by the one end thereof, the wires of both couples having thermo-electric properties that vary differently according to the integrated neutron flow.

Abstract: A flat throttling gate for bulb-type turbines and the like which is installed in a draft tube of the turbine. The gate has a central cutout of arcuate configuration flanked by a pair of ramps which cam a pair of masks into respective chambers flanking the guide slot for the slide body. Actuating mechanisms, e.g. springs, bias the masks against the valve body. In the withdrawn position of the valve body, the throttling cutout boundary, the masks and the wall of the draft tube define a circular flow cross section. In the inserted position of the valve body, a narrow flow cross section is provided between the wall of the draft tube or a lining thereof and a boundary of the cutout.
