Abstract: By means of Water Wave Power acting upon floats, attached to and made part of mechanical contrivances devised within the context of this invention for which the name of HYDRO-UNDULATORY POWER ARRESTERS has appropriately been chosen, water surrounding the structure is to be pumped positively or forcefully and continuously at that, to locations higher in elevation than the level of the water in the basin where the devices are installed or against a water system which comprises one or more hydro-pneumatic tanks, so that summarily the entire scheme would amount to the building up of potential hydrostatic energy at the expense of Water Wave Power, which under present circumstances is not utilized at all but simply allowed to go to waste.

Abstract: First and second endless conveyor arrangements respectively comprise a first and a second endless conveyor having a first and a second run. The second run adjoins the first run, and they together define an elongated path for fibrous material which is to be transported gripped between the runs. The first elongated endless conveyor comprises a plurality of parallel endless first elongated conveyor sections arranged side-by-side to define a plurality of elongated parallel first intermediate spaces extending along substantially the entire length of the first run. The second conveyor is similarly constructed so as to define similar second intermediate spaces. Along substantially the entire lengths of the first and second runs, the aforementioned sections of the conveyors project in direction from the respective run towards the other run into respective ones of the intermediate spaces of the other conveyor.

Abstract: Apparatus for defibering sheaths of fibrous material, particularly sheaths of abaca, in which the sheaths are transported sideways along a predetermined path by being gripped at opposite ends between the lower run and the upper run of an upper and a lower endless conveyor of a plurality of conveyor means which are so arranged with respect to each other that the sheaths while passing over portions of stripping blades extending transverse to the path are gripped at least at one end thereof, and conveyor means for use in such apparatus which comprise a plurality of adjacent pulleys along the lower run of the upper conveyor, a plurality of adjacent pulleys along the upper run of the lower conveyor, turnable about parallel axes offset in direction of the path with respect to the axes of the pulleys of the upper conveyor, in which each of the pulleys is formed with a plurality of circumferential grooves in which endless flexible means are located which engage and grip the sheaths for transporting the same.
