Abstract: A liquid turbine device including a turbine wheel, in which the turbine wheel includes more than one set of blades in radial succession.

Abstract: A wave power station device (1) of the kind wherein the waves flow up a ramp (12) and wherein the ramp (12) is provided with fixed openings (17), the openings (17) being arranged in such a way that water flowing up the ramp (12) will flow down through the openings (17) to an insignificant degree, whereas water flowing down the ramp (12) will essentially flow down through the openings (17).

Abstract: Apparatus and method are disclosed for adjusting the entry angle of a continuous web into an envelope-making machine. The entry angle of the web is capable of adjustment even though web supply roll, printing means, splicer, and other equipment normally located before the feed end of an envelope making machine are stationary and not attached to the envelope-making machine. The apparatus for adjusting web angle includes a first turn bar unit; a plate attached to the body of the envelope-making machine near the feed end of the machine, which can swivel about a point, the means of attachment being the point about which the plate swivels; and a second turn bar unit attached to the swivel plate. As the web advances into the first turn bar unit it is flat. The first turn bar unit turns the web so that as it moves from the turn bar unit it is on its edge or in edgewise orientation. The web remains on its edge as it enters the second turn bar unit.
