IPC: C21D9/60
Filed: 1951-11-16
Abstract: 701,338. Induction heating. OHIO CRANKSHAFT CO. Nov. 16, 1951 [Nov. 30, 1950], No. 26867/51. Class 39 (3) Successive lengths of an elongated metal strip, which is intermittently advanced longitudinally, are heated by an induction heater which continuously reciprocates relative to the strip. A metal strip A is intermittently advanced by a feeder C through an inductor unit D to a forge or press B. The inductor unit comprises a pair of inductors 10, 11 mounted on opposite sides of the strip, and each inductor consists of three laminated stacks 15 which are slotted to receive insulated conductors 19. The direction of current in the conductors lying directly opposite each other on opposite sides of the strip is arranged to be in the same direction, so that if the inductor unit were stationary a series of spaced heated bands would be produced across the strip. Liquid cooled frameworks 12, 13, spaced by insulated bars 14, support the inductors, and guides 22 are provided for the strip. The inductor unit is reciprocated on guide rails 30 by a rotated disc 31 and a connecting rod 33. By changing the connection of the rod on the disc the stroke of the unit may be varied. The inductor laminations may be arranged transversely of the strip and the inductor unit may be reciprocated at right angles to the strip length instead of, or in addition to, being reciprocated along its length.

Title: Improvements in or relating to television systems
IPC: H04N5/06
Filed: 1939-10-06
Abstract: 535,578. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Oct. 6, 1939, No. 27396. Convention date, Oct. 6, 1938. [Class 40 (iii)] A television signal train having synchronizing pulses in the manner shown in Fig. 1 is produced by generating sinusoidal oscillations at line frequency and double line frequency, for example by a tube 11, Fig. 2, feeding the line frequency oscillations through rectifiers, such as double-diode 65, to chains of tubes to produce three trains of shaped pulses, one at line frequency and two at double line frequency having pulses of different duration, and keying these by shaped pulses at frame frequency produced in two trains of tubes 114 &c. and 113 &c. fed with sinusoidal oscillations at frame frequency derived by frequency division from the unitially generated oscillations at double line frequency, the keying serving to mix the pulses into a tube 172. As shown, an electric oscillation of substantially sine wave form is generated by an electron discharge tube such as a pentagrid 11 in conjunction with a tuned circuit 27, 29, 30 in the manner of a Colpitts oscillator. The frequency of this oscillation is the line frequency of the television signal. Another tuned circuit 44, 45 connected to the valve is made to produce oscillations at double the line frequency, which is divided by three multi-vibrator stages 57, 58, 59 yielding a 60 cycle frequency equal to the mains frequency. This divided frequency and the mains frequency are fed to a phase detector PD, the output of which is connected through a filter F to an automatic control unit AFC to control and stabilize the line frequency oscillator 11. The line frequency oscillations are fed through a coil 61 to the tuned primary 68 of a transformer, the secondary 71 of which is centre tapped and connected to the cathodes of a push-pull rectifying tube 65. One anode 73 of this tube is connected to a train of wave-shaping tubes 77, 88, 95, 97 and the other anode 74 to a train of waveshaping tubes 78, 102, 108, 112. In addition a train of wave-shaping tubes 89, 98, 110 has the grid of its first tube 89 connected to the anode of the first tube 77, and the anode of tubes 89 and 102 are interconnected, the shaping action of these several chains of tubes being such that the output from tube 97 is a train of line frequency pulses and the outputs from the tubes 110, 112 are trains of double line frequency pulses of different width or duration. The frame frequency oscillations are fed to two chains of wave-shaping tubes 114 &c., and 113 &c. The first chain yields shaped pulses of opposite polarity in two leads 141,147 extending from time to, Fig. 1, to time t 3 , and the other chain yields shaped pulses extending from time t 1  to time t 2 . These pulses serve to trigger the outputs of tubes 97, 110, 112, whereby these outputs are mixed in the desired manner in the tube 172 to produce the signal train indicated in Fig. 1, the image signals being added to the output of the tube 172.

Abstract: 152,216. Haddan, R., (Regan, J. B.). Nov. 7, 1919. Fluid-pressure. - Relates to an electricallycontrolled venting-valve. The train-pipe 1 communicates by a pipe 4 with a casing containing three chambers 5, 6, 9. The chamber 5, into which the pipe 4 opens, communicates by an opening, the air of which can be altered by means of a screwed bushing 7, with the chamber 6. The chambers 6, 9 communicate by an opening in which is a valve 11 carried on the stem of a piston 13 working in the chamber 9. The portion of the chamber 9 above the piston 13 is provided with a vent pipe 19. The ends of the passage 16 are controlled by valves 15, 17 carried by the armature of an electro-magnet 23, so that, when the magnet is excited air can pass from the chamber 5 through the passage 14 to act on the piston 13 and keep the valve 11 closed. When the current is interrupted, the valve 15 closes and the valve 17 opens, thus venting the space below the piston 13 and allowing the valve 11 to open to vent the train pipe through the chambers 5, 6, 9 and the vent pipe 12.

IPC: H02P25/02
Filed: 1969-05-30
Abstract: 1,248,152. Control of A.C. motors; inductor alternators. NORTH AMERICAN ROCKWELL CORP. 30 May, 1969, No. 27646/69. Headings H2A and H2J. A dynamo-electric machine co-operates with commutator 14 which supplies signals representing the speed and position of rotor 16 to a  converter 18 associated with a power source 20. The converter 18 co-relates the commutator signal with a control signal from speed controller 22, and sets up fixed and travelling magnetic waves in field 24 and stator 26 respectively. The frequency of the input voltage to the stator 26 is adjusted so that the stator and field waves are stationary with respect to each other and separated by a predetermined phase angle, whereby the machine develops a desired torque. The power source 20 comprises a D.C. source 30 connected through oscillator 32, which provides a square wave output, to the commutator 14. Pulses from the commutator are rectified and shaped by bridge 56 receiving power from regulator 58 which operates to provide reduced voltage to the stator windings at decreased speeds of the machine. The regulator 58 generates pulses at a rate proportional to a command signal from the controller 22 through circuit 60 associated with current sensor 70. When the current fed to the stator 26 reaches a critical level, the output to the commutator 14 is reduced. The commutator signal is also applied to a pulse generator 72 connected to a converter 74 which delivers a speed-indicating signal to a differential amplifier 76. The latter also receives the speed command signal, the error signal driving a converter 80 feeding a field current regulator 82. A speed indicator 86 is provided. The converter 18 thus receives the commutator signal to maintain the stator field in step with the rotor field and leading it by a constant phase angle. The stator frequency is automatically maintained at a value proportional to rotor speed. The commutator comprises a primary field winding establishing a field between poles 40 and rotor 42 which is coupled to the rotor of the machine. A series of trains of pulses, each train being followed by a period of substantially zero voltage, is induced in secondary coils 46. The rotor 42 comprises a magnetic portion 50 and a non-magnetic portion 52. The pulses which are induced in the coils 46 are fed to the converter 18.
