Title: Improvements relating to compressed air apparatus for acoustic signalling
IPC: G10K5/00
Filed: 1952-02-25
Abstract: 691,728. Audible and like signalling apparatus. FORGES ET ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE JEUMONT. Feb. 25, 1952 [Feb. 27, 1951], No. 4855/52. Class 118 (ii) [Also in Group XXIX] Compressed-air apparatus for acoustic signalling intended to produce sounds of relatively short duration comprises an electromagnetic device having its circuit energized by the closing of a contact, and having its core or armature connected to a movable striker mass which is arranged to operate the control valve of a compressed-air signal or alarm by inertia effect and to return at the end of a predetermined time into a position in which the control valve is no longer actuated. A push-button B energizes the electromagnet M from a supply U and attracts armature A to which is secured a stem C carrying a slidable mass P on a shoulder D. The mass P is thus lifted to the level of the line a-a but due to its inertia continues to move upwards and strikes the end of a lever L which is thereby rocked against the action of a return spring R. The other end of the lever L depresses a poppet valve V to let compressed air from a pipe N operate a whistle S. At the end of a predetermined, but very short, time the mass P falls back upon the shoulder D, the lever L is restored and valve V closes, even though continued pressure on the button B may hold the armature A in the raised position. The desired time-constants of the system for the particular acoustic device and air-pressure used are obtained by suitable choice of the mass P in relation to the elasticity and inertia of the kinematic striking system, and it is stated that duration of signals of the order of 0.1 to 0.2 second have been obtained.

Filed: 1949-02-24
Abstract: 657,796. Helicopters. AUTOGIRO CO. OF AMERICA. Feb. 24, 1949, No. 5039. Convention date, Feb. 27, 1948. [Class 4] A helicopter is provided with a pivoted tailplane which is operable upon fore-and-aft movement of the pilot's control column to control translational flight, movement of the plane producing pitching moments resulting in the neutral or mid-point of the control column remaining substantially unchanged during hovering or translational flight. In the form shown, the control column 8, in addition to being connected to the cyclic pitch control mechanism 10, 11, carries an arcuate wiper arm 26 engageable with contacts 27, 28 to operate a reversible electric motor 18 controlling the tail-plane 12, and also carries an over-riding switch operated by a press-button 24 at the end of the column. If the aircraft is hovering and the column 8 is moved forwardly to initiate forward flight, upon actuating the button 24 the motor circuit is closed and the tail-plane moved to the position 12a. During its movement an increasing nose-down moment is produced, enabling the column 8 to be moved rearwardly, until the mid-position is again reached and the motor circuit opened. Upon release of the button 24 the column 8 may be moved to any position without moving the stabilizer plane 12. When reverting to the hovering condition the procedure is reversed, the column 8 being moved rearwardly with the button 24 depressed to return the surface 12 to its original position. The contact members 26, 27, 28 are so arranged that the column 8 may be moved through a small angle in either direction from the mid-position without the contacts 27, 28 being engaged by the member 26.

Abstract: 758,852. Turbines. BRITISH THOMSONHOUSTON CO., Ltd. Feb. 21, 1955 [Feb. 23. 1954], No. 5324/54. Class 110(3) An elastic fluid turbine drives either directly or indirectly a permanent magnetexcited alternator which supplies power to at least one A.C motor driving the main lubricating oil pump. The alternator may also supply power to an additional motor which drives a pump for feeding an hydraulic servo-system for operating the working fluid control valve or valves. Since the frequency of the alternator is dependent on the rotational speed of the turbine, the speeds of the motors also vary in dependence on this speed. Any required speed ratio between the alternator and the motor or motors can be obtained by arrangement of the number of poles on each motor or by gearing or both. The alternator may also supply power to a governor or speed indicating tachometer.
