Abstract
516,284. Control apparatus for air and water craft. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. June 18, 1938, No. 18172. [Class 135] Indicating or control apparatus installed in air or water craft which depend on a predetermined relationship being maintained between the speed of some rotary member such as the rotor of a gyroscope, tachometer or log and the forward speed of the craft, is provided with means operative when a departure from said relationship occurs to effect a variation of the speed of the craft to restore the relationship. In the arrangement shown in Fig. 1, the elevator 28 of an aircraft is actuated by a servomotor 25 under the control of a piston-valve 22 working in a follow-up seat 23 coupled by a link 32, lever 30 centralized by a spring 33 and viscous element 29 to the servomotor. The piston-valve is actuated by two coupled diaphragms 14, 15, the outer face of the diaphragm 14 being subject to the output pressure of a centrifugal pump 18 rotated by the rotary member acting through mechanical, electrical, hydraulic or pneumatic means. The space between the diaphragms is connected to a static pressure tube 35 while the space on the outer side of the smaller diaphragm is connected to a Pitot tube 17 to detect variations in translational speed. A pressure gauge connected to the chamber 11 and to the static pressure pipe indicates the difference between pump pressure and static pressure and may be graduated in air speed. In a modification, the larger diaphragm is subject to the pressure produced by the Pitot tube and the smaller diaphragm is subject to the output pressure of a centrifugal pump supplying motive fluid through a reducing valve to drive the rotary member. Specifications 129,727, [Class 97 (ii)], and 422,813, [Group XX], are referred to.
