Abstract: Abstract of the Disclosure A process for producing a catalyst comprising activating a supported chromium oxide at a temperature within the range of 500-2000°F; thereafter treating said thus-activated catalyst with from 0.5-10 weight percent, based on the weight of said catalyst of a hydrocarbyl aluminum hydrocarbyloxide at a temperature below 80°F.  Ethylene homopolymers and copolymers are made in a particle form process over a catalyst which is treated as a relatively low temperature with aluminum hydrocarbyloxide.  This catalyst is capable of pro-ducing high melt flow polymer at lower temperatures and also produces polymer having exceptionally high shear response.  This catalyst is useful for produc-ing ethylene homopolymers and copolymers in a particle from process.  There are certain applications where it is necessary to have properties such as high shear response of the type which can be obtained with solution process polymers.  In accordance with the invention, such a polymer can be produced in slurry systems utilizing the catalyst made as described hereinabove.

Abstract: DIGITAL COMMUNICATIONS SYSTEM WITH IMMUNITY TO FREQUENCY SELECTIVE FADING                      Abstract of the Disclosure A digital communications system with increased resistance to frequency selective fading.  Digital signals to be transmitted are phase shift modulated upon a spectrum spreaded carrier.          The carrier is generated by mixing the output of a band spread oscillator with a locally generated IF oscillator signal.          The signal thus obtained is divided into transmission periods, each of which is longer than the maximum spreading time of the nonlinear transmission medium.  The increased bandwidth occupancy thus obtained increases the immunity of the trans-mitted signals to frequency selective fades moving across the allocated bandwidth.  The signals are received by a differentially adaptive receiver which automatically adjusts its response to the envelope of received signals.

Abstract: Abstract Wastewaters heavily laden with organic compounds and con-taining viruses and other microbioligical flora are sterilized and maintained sterile for prolonged periods of time by the addi-tion of a base, such as lime, and a quarternary compounds, pre-ferably cetyl pyridinium chloride, in amounts to maintain the pH of the wastewaters at about 9-11, or higher, and with suffi-cient quaternary compound for suspended solids present. This prevents the formation of methane gases, which are tentative hazards in that they are inflammable, asphyxiant and narcotic. Similarly, toilets are rendered sterile by the addition of the base and quaternary compound so that, upon flushing, aerosols generated will not contain active infectious agents.  All bacteria and fungi are inactivated under the basic condition by the addition of quaternary compounds.  Viruses are also in-activated under these basic condition but only with quaternary compounds which contain the pyridinium moiety.  The disclosure includes products for and method of sterilizing wastewaters. A number of examples are given.

Abstract: ABSTRACT OF THE DISCLOSURE             A hydraulic motor or pump constituted by an inner and outer helical year pair.   The outer member of the pair is secured to one of the sections of at least one water swivel, and the inner member is connected to the other section by cooperting means associated with at least one end of said inner member and said other section, which prevent relative rotation while permitting relative gyration of said inner member with respect to said outer member.  The stationary section of said swivel serves as a mounting means for the device.  One or more gears, sprockets, pulleys or propellers may be secured to the rotating member of said pair, if it is the outer member which rotates, or to the rotating section of said swivel.  By driving said rotating member,fluid may be pumped through the device, the direction of flow depending on the direction of rotation.  By pumping fluid, by means of a separate pump,through said gear pair, the rotating member is caused to rotate in one direction or the other, depending on the direction of flow through said gear pair.  With at least one propeller mounted on at least one rotating swivel section, or on the outer member if it is a rotating member, and driven by a separate pump, the device has utility for propulsion of a boat, barge, or semi-submersible well drilling platform, or for directional thrusting thereof, or with gears, sprockets or pulleys mounted on at least one rotating swivel section, it may simultaneously be used for driving auxiliary equipment.          When the rotating member is driven by the use of gears, sprockets or pulleys, it may serve as a bilge pump.

Abstract: SINGLE READ STATION ACQUISITION FOR CHARACTER RECOGNITION     Abstract of the Disclosure To read characters printed on a document it is transported beneath a self-scan photocell array extending substantially the entire width of the document.  Output signals from the photocells of the array are scanned by a plurality of channels, amplified and converted into a digital data format representing the character patterns.  The digital data is then processed to memory electronics and search electronics to select lines of character pattern data for transmission to a character recognition unit.  The search electronics compresses the character data into search segments to evaluate the top and bottom position of character lines.  Further, the search electronics determines line linkages between the elements of one search segment of compressed data and the elements of the preceding search segments for future processing in a line tracker.          The line tracker provides signals to extract character lines from a temporary storage for transmission to a line block memory.  When the parameters of selected lines are determined by the line tracker of the search electronics the character data in the line block memory is unloaded into circuitry that functions to select data to be routed to read electronics for processing to a character recognition unit.
