Abstract: ABSTRACT   A screw conveyor composed of a plurality of modules mated end to end and of identical integrally molded construction. Each module is molded of a suitable plastic material and has integrally formed therewith a cylindrical body, a coaxially disposed tube within the body, and a web helically disposed between the coaxial tube and the cylindrical body. The module includes ends mateable with corre-sponding ends of like modules to provide a screw conveyor of intended length and which is rotatable as a single unitary structure. Each module may have a sheave integrally molded thereon for mating with a V-belt drive. Alternatively, the modules can be of open form each having a helical web molded on a central tube preferably having a non circular core and adapted for end to end mating with like modules to provide a screw conveyor of desired length.  This open type of screw conveyor can be readily retrofitted to systems having conventional metal conveyor screws.

Abstract: POLYPHENYLENE ETHER RESIN BLENDS MODIFIED        WITH SATURATED DIBLOCK COPOLYMER              ABSTRACT OF THE DISCLOSURE           The impact strength after molding of blends of polyphenylene ether resin and non-EPDM rubber modi-fied polystyrene resin is enhanced by the inclusion of a hydrogenated diblock copolymer of an alkenyl aromatic compound and a conjugated diene compound.  The molded properties are comparable to those obtained with corresponding blends containing a triblock copolymer as an impact strength enhancer, but the diblock offers an economical and readily available alternative to the triblock.

In the preferred embodiment, the maximum pressure at which the gaseous hydrocarbon fuel is stored in the on-board storing means is in the range of approximately 100 psig to approximately 400 psig.  An apparatus for supplying fuel to a gaseous fuel consuming device, such as a gaseous fueled vehicle or the like, is also disclosed. The apparatus generally includes one or more gas compressors for compressing the gaseous fuel to a predetermined pressure, preferably approximately 400 psig.  The apparatus preferably also includes apparatus for cooling the compressed gaseous fuel at least to ambient temperatures. Sorbent filtering and storage means are also preferably provided for maximizing the amount of fuel to be stored in the apparatus in order to supply a quick initial charge of the gaseous fuel to the vehicle or other gaseous fuel consuming device.

Abstract: RADIOTELEPHONE TRANSMISSION POWER CONTROL            Abstract Power levels of first and second stations in a cellular radiotelephone system are dynamically adjusted from only one of them.  The second station receives signals from the first and, on the basis of the level of those signals, first adjusts its own transmitter power level to be within a predetermined range and then directs the adjustment of the power level of the first station to be within a predetermined range.  Parameters used in processing call handoffs are also adjusted to correspond to the power level adjustments to prevent false handoffs due to the power level changes.

Abstract: ABSTRACT OF THE DISCLOSURE     A system for producing improved halftone images from continuous tone input images, the pixels of which have been digitized as gray scale values, using a printer having the capability to print a set of output pel patterns producing a respective set of discrete gray scale values, is disclosed.          Blocks of pel patterns with discrete gray scale values approximating the gray scale values of the input pixels are selected for printing, and the error in a first block due to the difference between the gray scale value associated with the block and the gray scale value of the corresponding input pixel, is determined. To diffuse this error it is distributed to at least two adjacent blocks using a random number generator to determine the dis-tribution such that a random fraction of said error is distributed to one block and the remainder is distributed to the other block. This error diffusion process is carried through the adjacent blocks taking into account the error fraction already as-signed. For edge enhancement the brightness gradient surrounding each input pixel is deter-mined and a threshold value is set below which said gradient is classified as small and above which it is classified as large. When said gradient is small, the selected discrete pattern is printed for the pixel, and when said gradient is large, the pel pattern is altered and the block representing the pixel is printed biasing the pels therein toward the darker input pixels.

Title: Process for welding pipe ends and an insulating ring therefor

Abstract: "AN IMPROVED PROCESS FOR WELDING PIPE ENDS    AND AN INSULATING RING THEREFOR"                 ABSTRACT OF THE DISCLOSURE            An improvement is provided in a known process for welding liquid-filled aligned end sections of pipe.  The known process involves positioning a sleeve over the junction between the pipe ends and fillet welding the two ends of the sleeve to the pipe ends.  The improvement comprises providing an insulative ring within each pipe end directly beneath the line along which the sleeve's fillet weld is to be applied. The ring is composite in nature, being formed of a heat-insulating liquid-disintegratable material coated with a second material which is liquid-impermeable but slowly dissolvable in the pipe line liquid contents. The ring is operative to reduce the rate of heat transfer, from the weld area to the pipe line liquid, during welding.  With a ring in place in each pipe end section, the engirdling sleeve is fillet welded to the pipe ends.  Subsequently, the rings are disintegrated over time by the liquid.  By slowing the rate of cooling of the weld and pipe wall in this fashion, embrittlement of the pipe wall adjacent the toe of the weld is avoided or reduced.           In a product aspect, a novel composite ring is provided.  The ring comprises a body of heat-insulating liquid-disintegratable material coated with a second material which is liquid-impermeable but slowly dissolvable in the pipe line liquid.  The second material dissolves with time to leave the insulative body exposed to the moving liquid, which gradually removes it in the form of bits and pieces of pulp.

Abstract: Abstract of the Invention Vector magnitude approximating logic using logarithms of the vector's orthogonal components to select multiplier scaling constants and to minimize arithmetic-function and hardware complexity.  The apparatus is particularly appli-cable to a high-throughput, pipelined, digital signal processing application such as radar.  The vector magnitude is approximated by multiplying each component of a complex number representing the vector by selected scaling constants and then by summing the two resulting products.  The scaling constants are selected by feeding each orthogonal component of the vector into one of two identical logic arrays which determine the base-2 logarithm of the absolute value of each component.  The resulting logarithm values are fed, in parallel, into a third logic array which outputs an address to real and imaginary constant read-only memory generators for providing respective scaling constant pairs which are used to compute the approximate magnitude of the vector or complex number representing the vector.
