Title: Partial response channel signaling systems
Inventor: FORNEY G DAVID JR
IPC: H04L27/38
Filed: 1988-02-23
Granted: 1992-08-18
Abstract: Partial Response Channel Signaling Systems Abstract of the Disclosure Apparatus for generating a (running digital sum) sequence of digital signals XX and/or a (partial response coded) sequence of digital signals yk, k = 1, 2, ..., such that Yk = XK + xK-L, L an integer, in which the yk signals are a sequence in a given modulation code,  In one aspect, the signals Yk are chosen to be congruent to coset representatives specified in accordance with a modulation code, a plurality of code constellations are used, and at least one constellation includes both a point with a positive sum of coordinates and one with a negative sum of coordinates.  In another aspect, the signals xk are chosen to be congruent to a sequence of alternate (precoded) coset representatives.  In other aspects, the Yk alphabet signals are evenly spaced, and a selectable, e.g., an optimal, tradeoff between Sx and Sy is made.  An N-dimensional modulation code is generated as a sequence of one-dimensional signals.  A maximum likelihood sequence estimation decoder reconstructs the estimated running digital sum, and generates a signal whenever the estimated running digital sum is outside a permissible range.  In another aspect, the decoder includes a modified maximum likelihood sequence estimator adapted to find MQ partial decoded sequences, where Q is the number of encoder states, and M is an integer.

Abstract: March 23, 1987 JFM/CJL/rag NOVEL SOLUBLE POLYIMIDESILOXANES AND METHODS FOR THEIR PREPARATION AND USE                              ABSTRACT      Fully imidized polyimidisiloxanes which are based on oxydiphthalic anhydride are soluble in diglyme which gives them particular utility in the micro-electronics industry.  The polymers are prepared from oxydiphthalic anhydride, a difunctional siloxane monomer and an organic diamine that provides an assymetrical structure in the polyimidesiloxane polymer chain.  The polyimide-siloxane can be prepared with functional groups which render them directly curable.  The polyimidesiloxanes can also be prepared with functional groups which when reacted with an unsaturated compound renders the polymers curable.  The products of the invention can be used in the form of solutions in the micro-electronic industry.  The polymers can also be used in wire and cable coating and to prepare films, fibers, and molded and extruded articles.

Abstract: ABSTRACT OF THE DISCLOSURE           A  method  is  provided herein  for  modifying  the surface state of a material or a medium, in particular of the paper and/or card type for the purpose,  in particular, of printing on the surface or medium.  The method   includes   the   step   of   substantially simultaneously applying a plurality of printing fluids on the surface of the print medium in such a manner as to provide dusting zones on the medium suitable for retaining  dusting  powder  particles  which  adhere exclusively on the zones.  A dusting powder is dusted onto  the medium including the dusting  zones,  the dusting powder comprising a substance which melts on heating and which is set after subsequent cooling. Excess dusting powder is removed by means of a flow of air.  The medium is then heated to fix the printing fluids  and  the  dusting powder  particles  retained thereby.    The  heating  step  is  performed  in  an atmosphere of hot air at a temperature sufficient to melt  the  dusting  powder  and  having  a  degree  of humidity sufficient to counter a large drop in the humidity  of  the  medium under  the  effect  of  the heating.

Title: Method and apparatus for improving video scrambling and employing split sync pulses
Inventor: FARMER JAMES O
IPC: H04N7/171
Filed: 1989-04-28
Granted: 1994-02-15
Abstract: A METHOD AND APPARATUS FOR IMPROVING VIDEO     SCRAMBLING AND EMPLOYING SPLIT SYNC PULSES            ABSTRACT OF THE DISCLOSURE      This invention discloses a new and improved method of scrambling video signals by inversion of the video information by splitting the sync pulse into plural portions and transmitting each portion of the sync pulse at a predetermined level. This improves the quality of the recovered video compared with other video inversion systems by rendering the video less sensitive to variations in the modulation depth of the modulator carrying the inverted signal, the demodulation sensitivity of the demodulator and the stability of the recovery circuits. The invention further provides additional security against pirating by allowing the scrambling circuit to operate in diverse modes, each of which will cause a TV to react differently should a conventional pirating device be employed. The invention also renders the signal capable of being transmitted with unmodified modulators of the type normally employed in the CATV industry.

Abstract: A rotary hoe provided with a hub, shaft, bearings and  cultivating  teeth  is  suspended  individually onto a bearing construction such that retroversion of the axis of rotation of the hoe-body with respect to the normal to the ground-surface  amounts  to  0-75°  in  the  plane  of  the direction of advance,  while  lateral tilting  in a plane perpendicular to  the direction of advance lies in the range of between 3 and 75°.   The hoe comprises a hub and a plurality of arcuate teeth which extend radially from the hub and are bent backwards in relation to  the natural sense of  rotation  during  work performance.    The  teeth  are arranged so  that, in course of hauling, they penetrate into the soil and perform a motion crossing the direction of progress.  The symmetry axis of the cross-section of the tooth penetrating into the soil is adjusted in relation to the axis of rotation, so that, at the moment of reaching the soil, a vertical motion is performed, whereby the angle (.alpha.) enclosed by the plane of rotation of the hoe-wheel and the soil-surface corresponds to the angle (.gamma.) enclosed by the symmetry axis of the tooth cross-section and the axis of rotation.
