Title: Improvements relating to the regulation of the power output of aircraft motors
IPC: B64C11/30
Filed: 1936-03-20
Abstract: 472,177. Fluid pressure servomotorcontrol systems. SIEMENS APPARATE UND MASCHINEN GES. March 20, 1936, No. 8422. Convention date, April 30, 1935. [Class 135] [Also in Group XXXIII] A control system for an aircraft motor driving a propeller having a variable speedthrust valve in which means are provided for automatically controlling the charge supplied to the engine and for controlling the speedthrust value of the propeller, has a common control for adjusting the basic' settings of the two regulators so that the speed and torque of the engine are so related to one another that mechanical and thermal overloading of the engine are prevented. In the form shown in the Figure the blades 2, 3 of the variable pitch propeller are adjusted by an oscillating vane motor 8 acting through spur and worm gearing under the control of a piston valve 5 actuated by a centrifugal governor 1. The engine throttle valve 16 is operated by a double-acting piston 25 controlled by a piston valve 21 actuated by a capsule 18 arranged in the induction pipe and adapted to act on the valve through a cam 20. Both control valves are provided with adjustable seat sleeves simultaneously adjusted by a cam 28 on a shaft 29 provided with a hand wheel 30 and indicator 31. To compensate for the effect of varying altitudes the anchorage of the capsule 18 may be adjusted by a power piston 39 controlled by a piston valve 41 actuated by an aneroid capsule 33. This piston acts through a sliding cam 36 and is coupled by a lever 38 with a follow-up sleeve 40 surrounding the valve 41 A cam 42 on the shaft 29 puts this supplementary regulator out of action when the other regulators are adjusted so that the motor delivers maximum output. In a modification the throttle valve is regulated in accordance with the torque delivered by the engine This torque is measured by the slight movement of the resiliently mounted fixed annulus of a bevel epicyclic transmission gear and is transmitted by toothed gearing to the control valve Y which is provided with a dashpot. Instead of using torque responsive device a meter responsive to the variations in the specific volume of the charge in the induction pipe may be used.

Title: A new or improved method and means of producing sounds
IPC: G10K9/10
Filed: 1919-04-04
Abstract: 146,582. Goold, J. April 4, 1919. Bell-operating mechanism, mechanical and hand and foot; diaphragm, plate, rod, and tube vibrators.-Means for producing sounds comprise a primary element set in vibration by a secondary element, the period of the latter being slightly' quicker than the period of the primary element; impulses received from a source of energy, acting upon and through the secondary element, set up and intensify uniform vibrations in the primary element. Various constructions are described. As shown in Fig. 1, the primary consists of a steel disk a., mounted between three pairs of pin points c on a fundamental nodal circle. A steel rod d, secured at one end to the centre of the disk a, and carrying at its free end a tip e of hard steel, constitutes the secondary. A wheel f is revolved. against the tip e, thereby setting up vibrations in the primary and secondary elements. As the rod d vibrates slightly quicker than the disk a, the tip e during its return stroke is just able to pass to its initial position without contacting with the wheel. As shown in Fig. 2, the primary a consists of a disk of steel or glass, mounted between triple-footed spiders engaging its nodal circle, and having a hole in the centre to clear the spindle c. The secondary comprises two steel oval rings d, inclined to the disk a, as shown in Fig. 3. Each ring has a tip e, consisting of a small piece of raw hide. leather, fibre. or the like. In this example the energy is first imparted through the primary to the secondary, which reacts on the primary. As shown in Fig. 5, the primary is a gong a, supported at its centre and carrying the secondary d, the tip of which contacts with the wheel f. As shown in Fig. 6. the steel disk a is clamped at the edge, and the energy from the secondary d is transmitted by a needle d<1> inserted between a depression at the centre of the disk and one just behind the tip of the secondary. As shown in Fig. 9, a rigid disk a, in conjunction with supporting-springs a<1>, form the primary, the secondary comprising the rods d supported on the disk a within the coil springs a<1>, and energized by the rotating wheel f. Figs. 10 and 11 show a construction electrically operated. The secondary d is a crook-shaped spring having a hollow in its tip to receive the apex of a quadrant d<1>, which rolls between guides near the centre of the primary a. On closing the circuit the secondary is attracted, and its tip striking the wheel f is thrust outwards and gives an impulse to the disk a, at the same time breaking contact between the tip and the wheel. The secondary element may be of crown form as shown in Fig. 18, with tips all joined together in a circle. The primary may be made from steel, glass, celluloid, or stretched parchment &c., and the secondary formed as a rod, tube, ring or loop, or any section of tube supported at one point of its rim and carrying a tip at another point. The tips may be made of sapphire, steel, iridium, raw hide, leather, cork, wood, celluloid, gut, rubber or fibre compounds &c.

Title: Apparatus for precisely measuring lengths
IPC: G01B9/02
Filed: 1955-03-24
Abstract: 772,097. Length measurement apparatus. SOC. GENEVOISE D'INSTRUMENTS DE PHYSIQUE. March 24, 1955 [March 30, 1954], No. 8615/55. Class 40 (3). An apparatus for the precise measurement of lengths which comprises a semi-reflecting mirror C whereon the reflections of a monochromatic light source S from a mirror m1, movable for measurement with reference to a scale r in conjunction with an optical comparator, and from a second fixed mirror m2, are combined and received by a photo-cell device b in a manner similar to that described in Specification 742,372, is characterized by the introduction of a glass wedge 18 in the path between the mirror C and mirror m2, the wedge 18 being oscillated by energization of a coil 21. Due to the action of the wedge 18, the luminous intensity received by the photo-cell b passes through a maximum when there is phase agreement on the semi-reflecting surface between the two beams of rays reflected by the mirrors m1 and m2 and through a minimum when there is phase opposition. If the position of the mirror m1, which may be adjusted by energization of the coil 14 of a magneto-striction device MS, is such that there is phase agreement with the rays from mirror m2 at the time when the oscillating wedge 18 is at the middle of its movement, the times of maximum luminosity passing to the photo-electric cell b, will occur at regular intervals and the needle of a measuring instrument i responsive to a modulated form of the signals received by the photo-cell b remains in a zero position. If, however, the mirrors m1 and m2 are not in phase when the wedge 18 is in mid-position, the maximum and minimum luminosities will follow each other at unequal periods and the measuring instrument i will accordingly register a reading dependent on these intervals. The apparatus according to the invention overcomes the disadvantages of that described in Specification 742,372 in which successive maxima and minima of luminosity are not very pronounced. It is stated that it is possible using this apparatus to determine a maximum or minimum illumination and therefor the position of mirror m7 with a precision equal to <SP>1</SP>/ 1000  and even <SP>1</SP>/ 10000  of a fringe provided the light is absolutely monochromatic and the optical surfaces quite plane. Specifications 555,103, 581,930, [both in Group XL], 684,435 and 686,274 also are referred to.
