Title: Improvements in or relating to engine speed control mechanism
IPC: B64C11/44
Filed: 1937-07-30
Abstract: 496,510. Screw propellers. UNITED AIRCRAFT CORPORATION. July 30, 1937, No. 21173. Convention date, July 30, 1936. [Class 114] [Also in Groups XXVI, XXXV, and XXXVII] The speed of an engine is varied and controlled by adjusting the pitch of a screw propeller driven by the engine in response to a centrifugal governor, the loading of which is varied. The governor adjusts the pitch of the propeller through hydraulic mechanism and the loading spring of the governor is adjusted by an abutment moved by the wheel 32. An electric motor 42 drives through worm gearing a shaft 50 gearing with the wheel 32. Closure of a switch 104 to make contact with 110 causes current to pass through the field winding 114 and rotate the spindle 50 until the nut 60 engages the stop 64 and closes the switch 74 whereupon current flows through the field winding 113 and stalls the motor and illuminates lamp 118. When contact 108 is made, current flows through the field winding 112 and rotates the shaft 50 until the nut 60 engages the stop 66 and moves the cam 86 to engage the clutch 90 which rotates and operates switch 98 to open contacts 109 and close contacts 116 and current passes through the field winding 114 and reverses the motor when the clutch is released and the contacts 109 are made again. The motor hunts at this limit of its movement. Fig. 6 shows a multi-engined aircraft fitted with means for maintaining the engines in synchronism. The master engine 120 drives an alternator which supplies synchronous motors 122a, b, c. Each engine 120a, b, c drives alternators each supplying a synchronous motor 136a, b, c, and arranged as shown so that each motor, e.g. 122a and 136a drives elements of a differential gear and differences in speed cause movement of the third element of the differential gear to operate a switch to adjust the loading spring of the governor, in the manner described above, to adjust the propeller of the engine 120a.

Filed: 1935-07-26
Abstract: 454,457. Turning-gear. TANGYES, Ltd., Cornwall Works, Smethwick, Birming- ham, and FIELD, H. O., Cromwell House, Homefield Road, Bromley, Kent. July 26, 1935; No. 21255. [Class 7 (v)] An engine-starter comprises a compressed air or gas motor having a pair of interengaging relatively rotatable toothed members a in a closely fitting chamber b, compressed air or gas being admitted to the chamber at c and exhausted at d. A pinion e or a clutch member is carried by a shaft f splined in one of the members a and is moved axially into engagement with an engine member by air pressure on the end g of the shaft, which slides in a cylinder h. Compressed air is admitted to the cylinder h by a hand-actuated valve. When the pinion e meshes with an engine gear, the end g uncovers a port p admitting the compressed air through a pipe q to the inlet c of the motor. The end g may be formed with a byepass passage r allowing a restricted flow of air to the motor, causing it to rotate slowly during the meshing movement of the pinion. On releasing the air pressure in the cylinder h, the pinion is returned by a spring l. In modifications, the meshing movement of the pinion is effected manually or by a screwthreaded connection between the shaft f and the member a. Three or more toothed members a may be employed, air being admitted at more than one point when maximum torque is desired. Oil sealing may be employed in the motor, and the motor may be used as a compressor to replenish the air reservoir before being disconnected from the engine.

Abstract: 1,061,914. Measuring film density photoelectrically. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. April 9, 1965 [May 22, 1964], No. 21344/64. Heading G1A. In a densitometer for evaluating the exposure of a radiation film badge, means are provided for conveying individual films to and from a test platform and for moving the platform within a plane to bring specific areas of the film into register with the densitometer light source and detector, the platform being held stationary during test. The densitometer comprises the platform (13), Figs. 3, 4 (not shown), to and from which films are conveyed by transport belts (11, 12), and which is mounted to be movable along two spaced parallel rods (14, 15). The rods are clamped together at three places including one end (20) at which they are pivoted to move angularly together about a vertical shaft (16). In operation, a film is deposited on to the platform (13), which is then moved along the rods (14, 15) towards the measuring point, to bring a first area (4), Fig. 1 (not shown), into register. The mechanism controlling this is a cam whose track is designed to have twelve critical points and which is connected through a gearing system to a pair of linkages (26 and 28, 27 and 29) which move the platform along the rods. The outer edge of the cam plate also acts in a control function to cause pivoting of the rods (14, 15) about the axis (16), causing the platform (13) to be moved sideways and bring other particular areas of the film into register. The drive for the cam mechanism is through a Geneva mechanism to provide a dwell period, for measurement, between each successive movement of the cam and the corresponding new positioning of the platform.

Title: Improvements in and relating to centrifugal gas extraction plants
Inventor: HUITSON ROBERT ROSS
Filed: 1957-07-05
Abstract: 886,244. Centrifugal compressors; elasticfluid turbines. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 4, 1958 [July 5, 1957], No. 21372/57. Classes 110 (1) and 110 (3). In a centrifugal compressor for exhausting non-condensible gas from a steam condenser, surging at low mass flow is prevented by admitting an additional gas mass to the compressor. This is done by admitting atmospheric air from an inlet 7 by way of a valve 3, 4 to the exhaust side of the turbine which exhausts to the condenser. The valve spindle 21 is connected to the control gear for reducing the turbine output so that the valve 3, 4 begins to open when the turbine output is reduced to 75% of the full output. Before the turbine is started, a butterfly valve 8 is closed by hand and held in this position by a latch 12, 13. When sufficient vacuum has been produced in the condenser, the vacuum, communicated through a passage 18, causes downward movement of a bellows 16 to unlatch the valve 8, which is thereupon opened by a spring 10. Specification 885,506 is referred to.
