Title: Closed air system seismic wave generator
Inventor: WOODROW ANDREW B
IPC: G01V1/147
Filed: 1988-06-14
Granted: 1993-01-26
Abstract: Abstract of the Disclosure Apparatus for  generating  seismic waves  including an upstanding hollow  cylindrical  housing  within  which  an impact piston latched in a cocked position is adapted to be propelled downwardly by high pressure expanding gas in the confined chamber above it within the housing so as to strike a target plate resting on the ground adjacent the lower end of the housing.   After  each blow  against  the target,  the piston is retracted upwardly by means of hydraulic cylinders which recompress  the  gas  in  the  chamber  to its  original pressure.  Since there is no need for recharging the pressure chamber after each shot, economical rapid cycle operation is facilitated.

Title: Arrangement for reducing ringing in a flyback transformer
Inventor: HAFERL PETER E
IPC: H04N3/18
Filed: 1989-02-02
Granted: 1992-05-12
Abstract: RCA 85,045 ABSTRACT           A diode is coupled to a low voltage end terminal of a tertiary high voltage winding of a horizontal flyback transformer. The diode is back biased during trace and during a portion of the second half of retrace by a voltage that is coupled to the diode through a resistor from a B+ voltage source.  When the diode is back biased, the resistor dampens parasitic ringing current in the tertiary winding caused by the leakage inductance of the transformer.  During a portion of retrace, occuring prior to the time the diode is back biased, the diode is conductive and bypasses the resistor. This prevents the resistor from increasing the output impedance at the ultor terminal.

Abstract: THICKNESS CONTROL OF DIRECT CAST STRIP          ABSTRACT      A smooth roll skimmer 36 may be used in the casting of  strip 34  by the melt drag process to provide gauge control  and  a  smooth  upper  surface.   Liquid  metal  32 is cast on a moving chilled substrate 33 where it solidi-fies  to  a  strip.   The  skimmer  36  is  positioned  above the substrate 33 and at a fixed gap therefrom by convenient means,  e.g.,  by a rolling spacer 37 between the casting surface and the roll skimmer.   The roll skimmer is not chilled and is not used to solidify the liquid.  It meters and  smooths  the  liquid  prior  to  solidification  on  the substrate.       A parting agent may be used on the roll skimmer to prevent sticking and to reduce heat transfer.  A carbo-naceous soot from a partially combusted hydrocarbon fuel is a useful parting agent.

Abstract: According to this method, on transmission, the signal S1(t) from a low-rate digital channel is added to that S2(t) from a high-rate digital channel by over-modulation or superposition means (13) which generate a composite transmission signal S(t). On reception, the signal S2(t) from the high-rate digital channel is recovered thanks to regeneration means (24) operating on the composite transmission signal S(t). The signal S1(t) from the low-rate digital transmission channel is recovered thanks to means (25) for subtracting the composite transmission signal S(t), previously filtered by a first low-pass filter (31), and the regenerated signal S2(t) from the high-rate digital channel, previously filtered by a second low-pass filter (33).
