Title: Improvements in and relating to regulating systems for dynamo-electric machines
IPC: H02P9/18
Filed: 1929-11-21
Abstract: 348,710. Automatic regulators. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Thompson, L. W. ; 53, Baker Avenue, Schenectady, New York, U.S.A.) Nov. 21, 1929, No. 35647. Convention date, Nov. 21, 1928. [Class 38 (iv).] A rheostatic regulator, employed in the field circuit of a dynamo-electric machine for regulating a characteristic of the machine, comprises a dynamoelectric machine in association with a continuously acting electromagnetic eddy current brake both of which are subject to the characteristic, such as the voltage, of the machine being regulated. As shown in the Figure a series motor 26 and an eddy current brake 30, having a magnet winding 29, are both connected across the terminals of a machine 1 to be regulated. The shafts of the motor and of the brake are interconnected by a differential gear the planet carrier of which transmits a torque to a shaft 23 to operate the rheostat. This torque is balanced at normal voltage by a weight 33 connected through a yielding connection 36 to the shaft 23 and arranged in a dashpot cylinder. The rheostat has resistance sections 4 in the field circuit of the machine 1 connected to segments of a commutator 7 which are engaged by brushes on a yoke member 11 slidable on a rod 12. The brush carriers of the yoke are bridged by a second resistance 13 of lower value than the resistance 4 and the regulator shaft 23 causes a contact 14 to traverse the resistance 13 until, by contact with one or other of the brush carriers of the yoke, the yoke brushes are moved to place the resistance 13 in parallel with another section of the resistance 4. In a modification, Fig. 2 (not shown), the armature of a series: motor is mounted upon a shaft operating, against a balance weight, a similar type of rheostat, and the field element of the motor is connected to an eddy current brake the excitation of which is in parallel with the motor. The rheostat in this case has its sets of resistance elements connected respectively to two commutators arranged at opposite ends of the diameter of a ring encircled by the yoke member.

IPC: H03K3/04
Filed: 1955-12-13
Abstract: 845,987. Pulse amplifying and generating circuits. ELECTRIC & MUSICAL INDUSTRIES Ltd. Nov. 28, 1956 [Dec. 13, 1955], No. 35694/55. Class 40(6). A pulse generator comprises a distributed amplifier having at least one over-biased stage which is normally non-conducting so that when a pulse is applied to said stage a narrower pulse is produced at its output. Fig. 2 shows a pulse generator comprising a distributed amplifier consisting of tetrode stages 1, 2, 3, in which the anode and control grid circuits are fed from delay lines 13 and 20 so that in operation the grid voltage is such that if a positive-going pulse is applied to the grid line 20 from left to right only the peak of the pulse is amplified by the over biased stages 1, 2, 3 and a narrower and negativegoing pulse travels from left to. right along the anode line 13. The screen grid bias is preferably high so as to increase the anode swing, the tubes being biased beyond cut off in the intervals between pulses. The terminating resistor 23 causes a mismatch at the end of the line 13 so that the negative pulse travelling from left to right along the line is reflected as a positive pulse which travels back from right to left. This pulse is then returned via the delay line 34 to the grid line 20 so that the circuit is self-oscillatory and the repetition rate of the generated pulses is determined by the total delay time. In a modification the left hand end of the anode and grid lines may be directly coupled as shown at 36, Fig. 2. In a modification shown in Fig. 3 transformer 37 has its primary in series with a normal matched output load 23 at the end of line 13 and its secondary connected in series with input resistor 40 to the left hand end of grid line 20. The left hand end of the anode line being terminated by resistor 22. The current may be triggered by sinusoidal or triangular waveforms applied to the line 20 the line 34 then being removed, Fig. 1 (not shown); the circuit then being no longer self-oscillatory.

Title: A method of treating carbon black
IPC: C09C1/60
Filed: 1932-12-23
Abstract: <PICT:0404452/III/1> Commercial carbon black is treated to bring it into granular form and thereby increase its apparent density by subjecting it to turbulent agitation, with or without the application of heat, within a closed container so as to cause the particles to cohere and be formed by impact into substantially spherical granules; if heat be applied, it should not be such as to cause oxidation.  The treatment may be carried out in a ball mill or in a closed cylinder provided with agitating blades.  Granulation is facilitated by the addition of a portion of carbon black having the desired form.  As shown, a shaft 22 bears spaced blades 30 arranged at 60 degrees apart and inclined alternately at 45 degrees to the axis of rotation, the shaft being mounted to rotate in a closed cylindrical casing 10. Surrounding one end of the shaft 22 is a hollow shaft 26 carrying a bail-shaped scraper 34 arranged to rotate in the clearance space between the blades and the cylinder at a slower rate than the blades and in the same direction.  In operation, the cylinder is half filled with carbon black and, if heated, the temperature is maintained below 400 DEG  F.
