Title: Conductivity state monitor for thyristor transformer tap switching devices
Inventor: TARDY JOHN
IPC: H02P13/06
Filed: 1990-04-26
Abstract: CONDUCTIVITY STATE MONITOR FOR THYRISTOR    TRANSFORMER TAP SWITCHING DEVICES Abstract A transformer apparatus uses SCR devices as tap switching elements for a tapped winding of the transformer. A snubber circuit is connected in parallel with each tap switching element. Current flow in a snubber circuit associated with each SCR device is monitored to determine the present switched state of that SCR device. This monitored current flow is utilized by control circuitry to permit turn on of an SCR device only when all of the tap switching SCR devices are presently non-conducting.

Title: Method for seismic trace interpolation
Inventor: HORNBOSTEL SCOTT C
IPC: G01V1/28
Filed: 1990-07-20
Abstract: METHOD FOR SEISMIC                     TRACE INTERPOLATION          Abstract of the Invention A method for seismic trace interpolation by dip range analysis is disclosed.   In the preferred embodiment,  a series of dip ranges are defined by a plurality of dips.  A trace estimate for each of the dip ranges is generated by filtering with a mathematically integrated time shift in each frequency component of each seismic trace appearing in the dip range.  These filtered frequency components are then passed through a low pass filter.  The sum of the filtered frequency components is the trace estimate.  The seismic traces are then demodulated to obtain the trace envelopes whose values along the above mentioned dips are examined for continuity.  A continuity factor is developed for each dip and then each of the continuity factors is summed and the sum divided by the number of continuity factors to obtain a weighting function.  The weighting functions are multiplied with the trace estimates. and the results summed to obtain the interpolated trace.

Abstract: A bearing blanket is disclosed which extends through an extended nip defined by a shoe and a cooperating backing roll for pressing water from a formed web.  The blanket includes a woven-base fabric which defines a web side and a shoe side, and a single liquid impervious urethane layer which is applied to the web side of the base fabric such that the urethane layer thoroughly penetrates into and through the base fabric.  The arrangement is such that when the urethane layer is cured, the urethane layer defines a web face and a shoe face.  The web face is spaced relative to the web side, with the web face defining a plurality of vents for conveying water pressed from the web away from the extended nip.  The shoe face is substantially co-planar with the shoe side of the base fabric such that the shoe face is relatively smooth for cooperating with and moving relative to the shoe.

Abstract: Abstract of the Disclosure A TREAD FOR A PNEUMATIC TIRE HAVING HIGH DENSITY SIPING ZONES LOCATED IN THE SHOULDER REGIONS     The present invention relates to a tread for a pneumatic tire featuring a pair of shoulder regions each of which contain a high density siping zone.  Each high density siping zone is (a) circumferentially extending about the ground contacting portion of the should regions; and features (b) an inside edge and an outside edge with a total width between the inside edge and outside edge ranging from about 1.4% to about 4.5% of the overall tread width; (c) the outside edge of each high density siping zone being located from the nearest tread edge by a distance ranging from about 0.9% to about 6.5% of the overall tread width; (d) about 50% to about 80% of the surface area in each high density siping zone being ground contacting with the remaining percent of area being siping; (e) no more than 50% of the siping arranged in the circumferential direction; and (f) at least 75% of all sipes within the high density siping zone is arranged so that their end portions are laterally aligned with or overlap in the circumferential direction with an end portion of another sipe within the high density siping zone.  When the tread width of the pneumatic tire is, for example, eight inches (203.2 mm), the total width between the inside edge and outside edge ranges from about 3 to 9 mm and the outside edge of each high density siping zone is located from the nearest tread edge by a distance ranging from about 2 mm to 13 mm.  The high density siping zones reduce the tendency for shoulder edge chamfer wear by creating a weakened zone without the tendency for tearing of tread rubber associated with decoupling grooves.
