Abstract: ABSTRACT OF THE DISCLOSURE          There is disclosed a high speed pulse train generator for generating a train of pulses having arbitrarily close spacing.          The apparatus in one form consists of a generator loop, comprising a fiber optic waveguide looped through a directional coupler, with the output fiber serving as the input fiber for a similarly structured multiplexer loop.  The lengths of the two loops are adjusted such that the time difference in the propagation times of light around the respective loops is small compared to the time of propagation around either loop.  The times are adjusted to obtain any arbitrary spacing of the pulses in the output pulse train which comprises interleaved pulse trains resulting from each pulse input to the multiplexer loop.  Also disclosed is a single loop embodiment for bi-directional data rate transformation and methods of using all the embodiments.

Abstract: ABSTRACT         A multi-row crop harvesting attachment for use in combination with a combine consisting of two or more drive sections having a guide edge on each of its two sides, platform sections positioned between each pair of drive sections, each platform section having a guide edge on each of its two sides, each platform section's guide edge in transverse opposition to the adjacent drive section guide edge,and two divider sections positioned outside of each of the outer most drive sections, each divider section having a single guide edge, each divider section's guide edge in transverse opposition to the adjacent drive section guide edge.  A longitudinally rearward and narrow flightway for crop stalks is formed by the opposed guide edges.  The drive sections further consist of two augers, each positioned over a flight-way adjacent to the drive section for guiding crop stalks longitudinally rearward along the flightways.         The harvesting attachment further consists of a locking cam, for mounting the harvesting attachment to a combine, which distributes the harvesting attachment's weight upon the front upper side of a combine's cross auger trough and which is connected to the upper frame of the cross auger trough.  A mounting bracket is pivotally connected to the locking cam at a point tending to rotate the cam about its weight distribution point and away from the upper frame of the cross auger trough.          The mounting bracket is shaped so that the center of gravity of the remaining portions of the harvesting attachment force the frame to rotate under and contact the under side of a combine's cross auger trough.

Abstract: ABSTRACT OF THE DISCLOSURE    A picture transmission system is adapted to code picture data by a variable sampling rate coding system to transmit the same.  Picture data are stored in a frame memory of a transmission area so that differential values between the same and predictors from a predictive circuit are obtained by a subtracter and compression-coded by a variable sampling rate compression circuit to be transmitted.  The compression-coded differential values are expansion-decoded by a variable sampling rate expansion circuit so that original differential values are supplied to an adder.  The adder adds up the differential values with predictors,  to produce predictors for subsequent sampling points.   In a receiving area, transmitted codes are expansion-decoded by a variable sampling rate expansion circuit, so that the decoded values are added up with predictors from a predictive circuit by an adder to output the original picture date.          Preposition prediction and variable sampling rate decoding are thus combined to enable, in the receiving area, automatic correction of compression/expansion errors caused in the transmission area.

Abstract: ABSTRACT OF THE DISCLOSURE A flat permeable polyolefin membrane 10 to 500 um in thickness, which has in one surface thereof a compact layer formed of intimately bound fine polyolefin particles and possessed of fine pores and in the interior and the other surface thereof a layer formed of an aggregate of fine discrete polyolefin particles of an average diameter in the range of 0.01 to 5um so adjoined as to form fine labyrinth-ically continuing through pores andwhich, therefore, establish communication between the opposite surfaces of said membrane.          The method for the manufacture of the flat permeable mem-branes is characterized by the steps of mixing a polyolefin, an organic filler uniformly dispersable in the molten poly-olefin, and a crystal seed forming agent, discharging the molten resultant mixture through a die, bringing one surface of the discharqed molten membrane into contact with a cooling roll thereby cooling and solidifying the membrane, and placing the cooled and solidified flat membrane into contact with an extractant incapable of dissolving the polyolefin thereby extracting and removing the organic filler from the web of the membrane, wherein the temperature of the cooling roll is 10-100°C.

Phosphorus ions are implanted in the polycrystalline silicon layer at an implant energy between approximately 80 and 100 keV.  The surface of the polycrystalline silicon layer is oxidized to form an interpoly oxide, utilizing an oxidation temperature which, for the implant dosage of phosphorus ions used, is sufficient to make the interpoly oxide layer approximately 770 Angstroms thick.  The structure is then annealed at a temperature of approximately 1100°C in oxygen and HCl.  A second polycrystalline silicon layer is formed over the interpoly oxide layer, and the process completed in the conventional manner.

Abstract: ABSTRACT OF THE INVENTION          An apparatus and method for preventing damage to the mechanical components of a borehole inclinometer is disclosed.          The inclinometer uses a freely suspended pendulum to align with the vertical at a selected position in the borehole.  A compass connected to the pendulum rotates to an orientation defined by the earth's magnetic field.  To protect the components which suspend the pendulum, the pendulum is clamped between a timer and a lens as the inclinometer is lowered into the borehole.  At a selected time, the pendulum is unclamped and is permitted to reach an equilibrium, measuring position.  After a selected interval, the timer urges the pendulum against the lens to clamp the pendulum.  The inclinometer is raised from the wellbore, and the orientation of the pendulum relative to the lens is observed to determine the azimuth and inclination of the borehole.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed are hydraulic fracturing fluids of enhanced temperature stability containing boron crosslinked galactomannan polymers and methods of producing same.  The temperature stability of fracturing fluids containing galactomannan polymers is increased by adding to the fracturing fluid a sparingly soluble borate having a slow solubility rate as defined herein.  The sparingly soluble borate provides a pH in the range from about 8 to about 10, provides a source of boron for solublizing at elevated temperatures thus enhancing the crosslinking of the galactomannan polymer, and it also decreases the leak-off properties of the fracturing fluid.
