Title: Improvements in and relating to propelling aircraft or other vehicles by means of screw propellers
IPC: B64C11/42
Filed: 1938-06-21
Abstract: 500,783. Controlling variable - pitch screw propellers. JUNKERS FLUGZEUGUND-MOTORENWERKE AKT.-GES. June 21, 1938, No. 18408. Convention date, June 23, 1937. [Class 135] [Also in Group XXXIII] Propelling-apparatus for aircraft and other vehicles in which two or more mechanically interconnected variable-pitch propellers are driven by a single engine has the pitch of all the propellers controlled by a single regulator subject to engine speed or other conditioning factor, and acting through hydraulic pneumatic, mechanical or electrical apparatus. In the form shown in Fig. 1, two propellers 1, 2 are driven by a single engine 5 through bevel gears 7, 8, 9 and 13, 14, 15, 16. The pitch varying control rods 17, 18 are connected through bell-crank levers 19, 20 and links 23, 24 with a pair of floating levers 25, 26. These levers are at one end linked to hand operated adjusting levers 35, 36 and at the other engage a common slotted cross-head 30 movable by a centrifugal governor 31 driven by the engine. In the form shown in Fig. 2, the blades of each propeller are adjusted by a toothed gear servomotor 43, 44 arranged in the hub 21 and geared to the blades by spur wheels 45, 46, 47, worms 48, 49 and worm wheels 51, 52. Motive fluid from an engine driven pump 53 is supplied to one side or other of the motor through passages 62, 63 under the control of a piston valve 61. This valve which has a central annular groove always connected through a passage 59 with the pressure side of the pump 53 and a passage 77 connecting the space above the valve to the space below, which in turn is connected to the return line to the pump, is screwed on the end of an actuating rod 67 held against rotation by a square part. When the valve is moved from its central position fluid is admitted to one side of the motor and exhausted from the other to cause it to rotate and adjust the propeller blades. As the motor rotates it acts through gearing 71, 72, 73 and spindle 70 with a squared part 69 engaging a socket in the valve to rotate the valve so screwing it along the rod 67 until it reaches its neutral position and stops the flow to the motor. In a modification the control valve casing is secured to a fixed part of the plant and the return motion from the motor is transmitted through a rack and pinion and floating lever. In another form a double-acting piston arranged in the hub acts through racks .and pinions to adjust the blades and is controlled by a tubular piston valve sealing in the main piston. In the form shown in Fig. 5, a power device of this type controlled by an adjustably loaded centrifugal governor 31 is coupled to the pitch varying rods of both propellers by cranked levers 19, 20, links 23, 24 and floating levers 25, 26 The other ends of the floating levers are linked to a see-saw lever 144 included in the lateral steering gear so that when the rudder is turned the pitch of the propeller on the outside of the curve is increased while that of the other is reduced.

Abstract: 613,329. Liquid tanks; fluid-pressurerelieving devices. SOC. SAVOISIENNE DE CONSTRUCTIONS ELECTRIQUES. June 19, 1946, No. 18379. Convention date, Aug. 23, 1945. [Classes 69 (i) and 135] [Also in Group XXXV] A reservoir R is connected to a tank C containing a liquid dielectric by a pipe T, the lower end of which projects below the level of the dielectric, the upper end projecting above the bottom of the reservoir and being surrounded by a pipe U, which projects above the highest and below the lowest level that the dielectric reaches in the reservoir. In the tank between the cover and the dielectric is an air or gas space V so that, on the temperature increasing, both the gas in the space V and the dielectric expand, the dielectric being forced into the reservoir. On cooling, the dielectric returns to the tank, any sludge remaining at the bottom of the reservoir, whilst any lighter impurities floating on the surface of the dielectric are constrained there by the pipe U. The size of the gas space V is such that, if leakage occurs at the joint J on expansion of the dielectric into this space instead of the reservoir, the space would not be filled but an alarm would be operated.

Title: Improvements in and relating to radial flow fans
IPC: F04D29/62
Filed: 1959-06-03
Abstract: 884,218. Centrifugal fans. SELBACH, A., AMME, P., and AMME, W., [trading as POLLRICH & CO., PAUL]. June 3, 1959 [June 14, 1958], No. 18930/59. Class 110 (1). In a radial flow fan with a rotatably adjustable spiral casing, a peripheral wall of the casing rests on the base frame of the fan in every position of adjustment. In Fig. 1 a fan casing 1 with a spirally curved wall 3 and an outlet 2 lies partly in a recess of a base frame formed by two transverse section members 5, 6 and two longitudinal section members 7. The easing is supported by the members 5, 6 and is secured to the base frame by releasable clamping members 10 acting on outwardly projecting edges 4 of the casing. All positions of the outlet 2 can be obtained by rotating the peripheral wall on the edges of the members 5, 6. The " lower horizontal " position of the outlet (Fig. 5) is effected since the section member 6 has a smaller height than member 5, and after reversal of the base frame the support edge of member 6 is in a lower position. Intermediate " downwardly inclined " positions of the outlet (Fig. 6) are obtained by removing member 6 and replacing it by support brackets 11 adjustably mounted on the two side walls of the casing and secured to the base frame by the clamping members 10. The " vertically downward " position of the outlet is achieved by securing the rim of outlet 2 to the section members 5, 6 by a frame on the outlet. In Fig. 10 each side wall 9 of the casing is reinforced on the inside by a respective coaxial ring 9<SP>1</SP>, 9<SP>11</SP> of which the one peripheral edge is connected, to the casing side wall directly and the other edge to the casing side wall through the intermediary of a spiral-shaped sheet metal cone 9<SP>111</SP>. The driving motor 17 is secured to two section members 18 which are displaceable on the longitudinal section members 7 so that the tension of the driving belt may be adjusted to suit the varying position of the casing. In the case of fans with large output (Fig. 11) the rotational forces of the rotor are not transmitted through the casing but through a pedestal 19 supporting the bearing means 13 of the fan shaft and secured, independently of the casing, to the base frame, which is extended in the axial direction. The pedestal is displaceable on the base frame transversely the fan axis, and the walls of the pedestal, which carry the displaceable fan bearing 13 and the fan driving motor 17, are inclined to one another in such a manner that in both extreme positions adjustment of the bearing 13, the distance between the motor axis and the fan bearing axis is the same.
