Granted: 1991-07-09
Abstract: ABSTRACT A marine propeller     combines decreasing overall pitch from hub     to blade tip      and increasing progressiveness of pitch with increasing radii from hub to tip, and provides uniform loading from hub to tip.  The blade has a maximum transverse dimension              between the high pressure surface      of the blade and a straight line chord between the leading edge      and the trailing edge      of the blade. The ratio of this maximum transverse dimension to the length of the chord is ever increasing from hub to tip.  A para-bolic blade rake along the maximum radial dimension line      of the blade is provided in combination.

Abstract: ABSTRACT       A valve of the kind for controlling the flow of fluid from at least two alternative supplies in such a manner that reduction or cessation of one supply automatically causes the valve to switch to another of the alternative supplies comprises a cylinder having a piston slidable therein in a region between a first fluid inlet and a second fluid inlet. The piston has working surfaces of differential area  such that equal pressure on both sides of the piston biases the piston to one end of the cylinder. The valve has a fluid outlet with a first fluid flow path from the first fluid inlet to the fluid outlet,  and a second fluid flow path from the second fluid inlet to the fluid outlet and including an axial outlet bore.   The second fluid flow path is closable by the piston and is opened upon axial movement of the piston towards the first fluid inlet which is caused when the supply of fluid from the first fluid inlet fails, is arrested or falls below a predetermined limit. The first fluid flow path of the valve is permanently open thus rendering the valve fail safe.  The axial outlet bore of the second fluid flow path is formed through the piston and is closable by a seal in the cylinder against which an end of the piston is adapted  to abut  thus ensuring a compact valve construction.

Abstract: AN ABSTRACT          A pneumatic valve, designed to control/pressurize a memb-rane pump, comprises a valve body (1) having gates (8-12) for compressed-air-flow/operation/pressurization of said pump. The valve body is closed by ends (2), between which a plunger (5) is to move between two end positions. The ends of the plunger and the ends of the valve body co-ope-rate physically magneticly in order to generate just and ? only a retaining force, which constitutes a threshold for a certain minimum control pressuue from a control-air-gate (13 or 14) and guarantees a rapid initial movement as well as a rapid transfer of the plunger to its opposite end position. Permanent magnets (15) are inserted in said plunger ends and/or in said valve body ends and designed to co-operate with projections and/or recesses (17, 18, 20) in the opposite member in order to obtain a so called air-cushion-damping (Fig. 4).

Abstract: The inventor has found that, irrespective of track thickness or the material of which the track is constructed, the optimum track width for a thick film heater track is in the range of from 1.2mm to 2.1mm. Further advantage accrues in that for a given resistance the track is longer and may be conformed to a pattern to give improved temperature distribution. A heating element is also provided, comprising a plurality of thick film electrically resistive tracks (8) applied to the surface of an electrically insulative substrate and switching means (10) for selectively connecting one or more of said tracks to a power supply. The resistance and hence the operating temperature of the heating element may be varied by changing the track or tracks (8) connected to said switching means (10).
