Title: Improvements in and relating to starting and shutdown systems for the gas turbine prime-movers of electrically propelled locomotives
IPC: F02C7/275
Filed: 1953-06-19
Abstract: 729,693. Starting prime movers. GENERAL ELECTRIC CO. June 19, 1953 [June 21, 1952], No. 17021/53. Drawings to Specification. Class 38 (4). A locomotive driven by a gas turbine through an electric transmission carries an auxiliary generator which is driven by a diesel engine and used for starting the "turbine, the turbogenerator then functioning as a motor to crank the turbine. A switch automatically opens the electrical connection between the two machines when the turbine reaches such a speed as to become self-running. In one embodiment the plant also includes a battery for starting the diesel generator, a second auxiliary generator which is driven by the turbine, and a manually- or automatically-operated starting controller having an " off " position and five other positions, a latching system being provided which prevent the controller being advanced from one position to the next unless the plant has reached a predetermined condition in the first position. The controller effects the following operations in its different positions:- First position.-The auxiliary diesel generator is started from the battery of a normal electric starter motor, whereupon this generator is connected for charging the battery. Second position (which can only be attained if the diesel engine is running above a predetermined speed).-A contactor operates to stop battery charging and to connect the diesel generator to the main generator so as to motor the last and crank the turbine. Third position (which can only be attained if the turbine speed has reached say 10 per cent full speed).-A solenoid valve is operated to admit diesel fuel to the turbine to accelerate. At 10 per cent full speed the diesel generator is disconnected from the main generator and reconnected for battery charging. Fourth position (which can only be attained upon the turbine reaching 70 per cent full speed).-The supply of diesel fuel to the turbine is terminated and another solenoid valve is opened to admit a lower grade of fuel to the turbine. Battery charging is transferred from the diesel generator to the turbine-driven auxiliary generator. Fifth position.-The diesel generator is shut down and the circuit between the main turbogenerator and the traction motors is established. The turbine is shut down by moving the controller back through its five positions, which produces a reverse sequence of the above operations, " cool down " cranking occurring in the second position and the diesel generator, which starts up at the fourth position, eventually taking over battery charging at the first position.

Title: Technique for generating a digital segment file from common  depth point seismic gathers
IPC: G01V1/36
Filed: 1973-04-11
Abstract: 1429244 Seismic signal processing TEXAS INSTRUMENTS Inc 11 April 1973 [12 May 1972] 17329/73 Heading H4D  A digital file of data relating to reflector segments is obtained by applying various trial moveout and dip time-corrections to the traces of a common depth point (CDP) set to obtain stacked amplitude values within a threedimensional space having trace time, moveout and dip co-ordinates; detecting amplitude extrema within the space to estimate the actual moveout, dip, time and amplitude of reflection events relating to the depth point; comparing these estimates with similarly-derived estimates for adjacent depth points; and identifying reflector segments if the compared estimates agree within predetermined tolerances. In the embodiment described the traces are subjected to time-variant filtering and amplitude equalization prior to the application of the moveout corrections. An analysis of the filtered and equalized traces (details given) is made to determine parameters to be used in the subsequent processing, c.g. the trace time sampling interval, the increment between successive trial moveout corrections, maximum and minimum values of trial moveout, and the increment between successive trial dip corrections. A respective "moveout scan trace", MOS, i.e. a stack trace, is then obtained for each trial moveout correction applied to a CDP trace set. The MOS traces are subjected to the trial dip corrections to give respective "dip scan traces", DS, i.e. stack traces, for each trial dip correction. The resulting amplitude data points in moveout-dip-time space are searched for possible maxima. Whenever a point of possible maximum amplitude is detected the data points immediately surrounding it are examined and the point is validated if these surrounding ones are all of lower amplitude. Precise values of amplitude, time, dip and moveout for such validated points are obtained by interpolation between data points (details given) and are then edited and stored. The values for adjacent depth points are picked out from storage and compared: if they are consistent within predetermined tolerances a reflector segment is assumed to link the depth points and the segment data are stored.
