Title: Improvement in the method of connecting the windings of the electrical rotating converting machines known as 'metadynes'
IPC: H02K47/16
Filed: 1937-05-31
Abstract: 496,494. Rotary transformers. TUSTIN, A. May 31, 1937, No. 15014. [Class 35] A metadyne transformer adapted to be connected to its load in the " Figure 8 " connection has an armature winding of which the coil pitch is less or greater than the polepitch, and interpoles 12 ... 15, the excitation on each of which for the normal function thereof is provided by a winding connected with a respective brush 2, 3, 8 or 9, the interpole windings being connected with the brushes in such order that whilst the normal commutating action is produced by the interpoles, those components of current which, due to inequality between the two parts of the load circuit enter the armature at the several primary brushes and leave at the several secondary brushes or vice versa, will produce at the interpoles components of flux to generate in the armature conductors lying under the interpoles, voltages opposing the passage of such components of current through the armature. In the case of an armature having a short pitch lap winding as shown, or a long pitch wave winding, each brush is connected with the external circuits through the winding of that interpole under or adjacent which lies the trailing side of the coil which is directly connected to the brush through the commutator. If the armature has a long pitch lap winding or a short pitch wave winding, each brush is connected through an interpole winding adjacent the leading side of the coil connected to the brush.

Title: Pneumatic governors for liquid-fuel injection pumps
Inventor: NICOLLS WILFRED EDWARD WALTER
IPC: F02D1/06
Filed: 1953-06-01
Abstract: 732,187. Speed governors. C.A.V., Ltd. May 21, 1954 [June 1, 1953], No. 15175/53. Class 57. A pneumatic governor responsive to the pressure in the air-intake passage g of a reciprocatory internal combustion, engine, for controlling the output of a liquid-fuel injection pump a, and having an air-bleed device to stabilize, or prevent flutter of the governor when the pump is in or near the condition of minimum delivery is provided with a valve responsive to the pressure of the air from an engine blower j for over-riding the action of the governor stabilizing means. The governor consists of a flexible diaphragm d (or piston) which is connected to one end of the pump control rod b, loaded by a spring e and arranged to divide a hollow body part c into two chambers, one of these chambers being open to the atmosphere while the other is connected by a pipe f to the passage g at a position associated with the throttle i or between the throttle and the blower j. The air-bleed device includes a spring-loaded valve q having a stem u which causes it to be opened when the diaphragm d is displaced to the right, with increasing engine speed so that atmospheric air may enter the governor through a port o and an annular valve seating p. If the engine is running above a predetermined speed however the pressure of the air from the blower acts through a pipe r on a spring-leaded piston m (or flexible diaphragm) which closes the valve seating p and thus renders the air-bleed device inoperative.

IPC: B61L5/06
Filed: 1918-09-18
Abstract: 120,553. Monard, A. Nov. 8, 1917, [Convention date]. Electric operation and control; transmission mechanism applicable generally.-Railway points are operated from an electric motor 60 through a worm-wheel 63 formed as a nut and mounted on a screw 64 which is adapted to slide without turning and thereby reciprocate the points rod. The screw 64, as shown, is axially bored to receive the points rod 66, and is formed with a cavity to receive a number of washers 65 threaded on the rod, the friction between the washers and the rod being regulated so that normally they move together, but should the points be trailed through, or meet any obstacle, relative movement takes place. Any relative disturbance of the screw and rod is corrected at the next operation of the points. After completing its stroke in either direction, the screw 64 engages a lever 72 and through a spring-pressed plunger 73, releases and operates quickly the arm 69 on a shaft 68 whereby the motor circuit is broken and prepared for the reverse movement. The point tongues are connected to cranks 75, 76 fixed on shafts 77, 78 carrying cams 79, 80 adapted to engage arms 81<a> freely mounted on the shaft 68 whereby, when the points movement is correctly completed in either direction, the control circuit is connected so as to give an indication signal in the pointsman's cabin.

Title: Television broadcast system
IPC: H04N5/08
Filed: 1939-05-26
Abstract: 529,320. Television. HAZELTINE CORPORATION. May 26, 1939, No. 15761. Convention date, June 9, 1938. [Class 40 (iii)] Picture signals are transmitted by amplitude modulation and synchronizing pulses by frequency modulation of the same carrier, or vice versa. In the transmitter, Fig. 1, the picture signals from a cathode-ray apparatus 10 pass through the devices 16, 17, 19, 20, 21 22 to the aerial system 23, 24, the device 19 serving to suppress one side band, and the carrier wave being produced by a master oscillator 18. Saw-tooth and flat-top synchronizing pulses are produced by devices 12, 13 ; harmonics are generated by devices 25, 26 ; and these are mixed by devices 27, 28 and serve to trigger a frequency modulating device 29, which controls a frequency changer 20 in the aerial supply system or may be made to control the master oscillator 18 directly. A timing impulse generator 15 controls the synchronizing pulse generators 12, 13, 25 26 and also a pedestal impulse generator 14 connected to the amplifier 16 for the picture-signals. In the receiver, Fig. 2, the signals received by the aerial system 50, 51 are transmitted by the devices 52, 53, 54, 55 to the cathode-ray picture reproducer 56. The signals are also by-passed through devices 60, 61 to a vacuum-tube limiter 62 where the picture signals are eliminated, then through a broadly-tuned selector circuit 63 and an amplifier 64 to a modulation converter 65, this arrangement preventing back coupling. The converter 65 is so tuned as to convert the frequency modulation into amplitude variations and these are passed through a rectifier 66 to filters 67, 68 tuned respectively in correspondence with the devices 25, 26 of the transmitter and serving to control the scanning generators 57, 58. In a modification, the frequencies to which the carrier is shifted during line-scanning and field-scanning pulses are made different, the devices from D to B, C in the receiver are then replaced by two sharply-tuned selectors 81, 82, Fig. 2b, followed by rectifiers 83, 84. In another modification the harmonic generators 25, 26 may be omitted from the transmitter, in which case the devices from A to B, C in the receiver are replaced by a duration response separator, Fig. 2a.
