Abstract: 282,425. Loth, W. A. Dec. 18, 1926, [Convention date.]. Power - generating systems; vacuum engines.-A static suction apparatus is placed in a current of naturally moving fluid and connected to a motor capable of functioning under action of the suction produced. The apparatus comprises convergentdivergent or convergent-cylindrical nozzles opening into two opposite walls of a chamber connected to the motor conduit. In the apparatus shown in Fig. 1, convergentdivergent nozzles 12, 13 are arranged in a drum between the exterior and a central passage. The space 14 is connected to a motor conduit. In a modification, the member 2 is of rectangular form. Helical webs may be arranged in the nozzles to increase the suction. In a further modification, a rectangular cellular arrangement of nozzles is described. The action of the apparatus immersed in fluid is described. In the construction shown in Figs. 9, 11, the parts 12 are of rectangular cross-section. Other arrangements are described wherein the axis of the nozzles in a drum 2 are inclined in different planes at one parallel. The Specification as open to inspection under Sect. 91 (3) (a) comprises the application of the above type to power purposes either by the vacuum induced or by the pressure or velocity induced in a liquid or gas, or by both the vacuum and induced pressure. The apparatus may be worked by the pressure or motion of the water in rivers, lakes or the sea, or by a waterfall, or by the pressure produced by a dam, or by the wind to drive a vessel. An arrangement of suction elements operated by air and adapted to operate a motor 6 is shown in Fig. 2 (Cancelled). The elements 2A comprise convergent and divergent parts 12, 13 respectively arranged in vacuum chambers 14. The elements 2B have convergent and divergent parts 12, 13, the parts 12 having helical vanes. In the upper section, a smaller element is arranged coaxially in the part 12 of the larger element. The construction 2C comprises a convergent part 12, and a cylindrical part 16. In the convergent-cylindrical construction 2D, helical vanes are arranged in the part 12. The suction devices may be arranged on a pivot to take up the position of the air current, or they may be stationary, or they may be mounted upon a positively or automatically controlled, pivoted, flat or curved surface. Such a device may be used for propelling a vessel, Fig. 17 (Cancelled). An arrangement is described wherein a current of water sets up a vacuum and compression on each side of a motor respectively which is worked by the combined effect. A small power plant for domestic uses is described wherein a flow of water creates a vacuum in a chamber connected to a motor; the discharge water passes into a sink. In the construction shown in Fig. 22 (Cancelled), suction elements 2, 2<a>, 2b are arranged at the bottom of a chamber connected to a stream, a lake, or the sea. The suction created operates a motor 6, which may also be operated by fluid moving under pressure produced by a chamber immersed in a current of liquid or gas. The motor 6 may be liquid or gaseous operated. Pressure fluid may also be supplied to the motor from a chamber 9<a> arranged above the discharge from the suction elements. A construction is described wherein an anchored vessel or pontoon has suction apparatus arranged below it operating a motor mounted upon it. The motor operated by suction apparatus of the above type may be a turbine, or a double-acting piston engine with slide or like valves, or a single-acting piston engine may have its power face alternately subjected to vacuum and pressure, the other face being open to the atmosphere, or a multi-stage motor may be used. The power fluid may be circulated in a closed cycle. This subject-matter does not appear in the Specification as accepted.
