Title: Improvements in or relating to apparatus for removing coke from retorts
IPC: C10B33/04
Filed: 1923-06-15
Abstract: 221,024. Ride & Bell, Ltd., and Bell, G. June 15, 7923. Charging and discharging.-Apparatus for removing coke discharged from any one of a superimposed series of retorts includes a main frame 1 carried by wheels 2 on rails 3 parallel to the front of the battery of retorts. An endless conveyer 4 is carried round rollers 5, 6 mounted in a framework 7 of channel formation. The rear end of the framework is suspended by links 14 pivoted on the spindle of the roller 6, and the forward end is guided for vertical movement by guides 10 in which run rollers mounted on the framework 7, and is supported by chains or cables 11 passing over suitable pulleys to a winding drum 13. The conveyer 4 is driven by a motor 17 through gearing 19, 18, and a second motor 43 may be clutched by clutch members 45, 46, either to the drum 13 to raise or lower the forward end of the conveyer or to the wheels 2 to move the whole apparatus along the rails 3. A nozzle 24 adapted to bridge the space between the conveyer and the retorts 8 is pivotally sup- 'ported by arms 26 journalled in the framework 7. The nozzle can be adjusted to a retort mouthpiece by a handwheel 30 through linkage 27, 28, 29. By the use of suitable reversing gear the conveyer can be caused to discharge its load of coke into a furnace below the retorts. In a modification the nozzle 24 is carried by brackets having rollers running in the guides 10 and is normally supported by and travels with the forward end of the conveyer, but may be retained above its lowermost position by means of a detent which is normally held in operative position by a counterweight.

Title: Improvements in and relating to pulse generating circuits
IPC: H03K5/01
Filed: 1945-06-19
Abstract: 616,261. Pulse amplifying circuits. BRITISH THOMSON-HOUSTON CO., Ltd. June 19, 1945, No. 15650. Convention date, June 19, 1944. [Class 40 (vi)] In a pulse amplifying circuit in which a valve, feeding an inductive load is rendered conducting for the duration of a pulse, means are provided for suppressing the oscillations generated at the termination of the pulse by a feedback arrangement between the load and the valve. Positive pulses applied to the grid of normally biassed-off valve 3, Fig. 1, cause the anode potential to fall suddenly, thereby applying a negative potential to the cathode of the magnetron 9, shunted by the inductor 8 and stray capacity 17. At the termination of the pulse, due to the resonant circuits 8, 17 and 7, 8 the potential of the cathode of magnetron 9 commences to oscillate, Fig. 4 (not shown), and as it rises above earth potential, diode 18 conducts, causing the grid potential of valve 3 to rise and the valve to pass anode current and stop the oscillation. In a modification, Fig. 3, positive pulses are fed to valve 28, to cause it to conduct, the output being applied over transformer 31 as positive pulses to valve 35 feeding the auto-transformer 41 connected to the magnetron 42. The grids of the valves 28, 35 a.re biassed beyond cut-off, conducting only during the pulses. When the valve 35 conducts, the potential of the autotransformer input is driven negative, the diode 45 conducting and maintaining the cathode near earth potential. Upon the pulse ceasing the potential of the input of the auto-transformer 41 rises, and due to the oscillatory circuit the potential tends to become positive, the diode 45 then ceasing to conduct, so that a rise in potential is applied over condenser 47 and resistance 32 to cause the valve 28 to recommence conducting. Valve 35 is thus rendered conducting to reduce the amplitude of the undesired oscillations.
