Abstract: ABSTRACT OF THE DISCLOSURE     A corrosion resistant tubular air preheater in which combustion air is heated by heat transfer from flue gases from a furnace.  The heat exchanger is of a longitudinal type having a central enclosure of rectangular cross-section in which a plurality of tubular heat transfer elements are mounted.  Surrounding the central enclosure is an outer plenum.  Cold combustion air enters at the bottom of the outer plenum and circulates around and up the plenum to a series of openings on top of the heat transfer elements.  The partially heated combustion air then passes downwardly through metal tubes in the heat transfer elements and then passes outwardly to the furnace.  The minimum temperature in metal structure enclosing the combustion gases is controlled by two means.  One is the use of insulation in selected areas to limit heat transfer rate to cold air impinging upon metal surfaces.  The second method is by control of cold air flow incidence on or along heat transfer surfaces so as to minimize rapid heat transfer from any metal surface, which might chill the surface below the dew point.

Abstract: ABSTRACT OF THE DISCLOSURE A process is provided for preparing polyolefins by polymerizing or copolymerizing olefins in the presence of a particularly recited novel cata-lyst.  The catalyst comprises a solid component and an organometallic compound. The solid component is obtained by copulverizing (1) a magnesium halide, (2) a compound represented by the general formula Al(OR)mX3-m, wherein R is alkyl and/or aralkyl having 1 to 20 carbon atoms and may be the same or different, X is halogen and O < m ?3, (3) a tetravalent titanlum compound, and (4) a trivalent titanium compound, the trivalent titanium compound being present in a solar ratio with the tetravalent titanium compound of from 50:1 to 1:50. The organometallic compound component is a mixture of (5) a trialkylaluminum and (6) a compound represented by the general formula AlR'nX3-n, whereln R' is alkyl having 1 to 10 carbon atoms and may be the same or different, X is halogen and O< n < 3, the compound (6) being present in a solar ratio with the trialkyl aluminum of from 2:1 to 1000:1.  The yield of polymer per solid is remarkably increased when such process is used, dispensing with the step of removing residual catalyst in the polymer.  At the same time the bulk den-sity of the resulting polymer is heightened, the molecular weight distribu-tion thereof is widened and consequently the fluidity of the polymer in a molten state is improved.

Abstract: IMPROVED SYSTEM OF DATA STORAGE            ABSTRACT OF THE DISCLOSURE            In a Teletext transmission system data is transmitted in digital form during lines in the field blanking period of the composite video signal of a television transmission.  On reception the information is decoded to generate a display comprising a page having a predetermined number of rows of information in alphanumeric or graphics form.  The data is received in blocks comprising information digits each block associated with a respective group of two-part address inputs, one part providing page identification and the other data row information.  A plurality of serially accessed data storage registers is provided for the data rows, each uniquely corresponding to a selected one of the two-part address digits.  A decoder is responsive to transmitted address data to independently address the corresponding shift register via a first switch to write data into the store and is responsive to address data to read data from a selected register via a second switch for display generation.  Data entered into the shift register may be recirculated until required for display.  Transmission of data rows out of page and row number sequence is thus accommodated so that only data rows containing information and data rows needing updating need be transmitted.

Abstract: ABSTRACT OF THE DISCLOSURE To eliminate the high frequency portion of an input signal while permitting low frequency and DC portions to pass, the electronic filter utilizes an n-l order active network in combination with a capacitor to generate 2 shunt current, thereby providing a low pass filter having n-order operating characteristics.  Included in the active network is an active element, such as an operational amplifier, which responds to an input signal by creating a vol-tage across the capacitor resulting in a shunt current that in turn provides the desired filter characteristics.  In certain special cases the n-order ac-tive filter can utilize a differentiating element in combination with an n-2 order active network along with the capacitor to achieve n-order operating characteristics.

Abstract: Abstract of the Disclosure A wood treating impregnant is deposited in wood by a non-aqueous wood treating system that has the ability to control the distribution, to immobilize and to more permanently fix the impregnant in the wood. The wood is treated with a liquid carrier containing the impregnant and a reactive solvent so that both the impregnant and reactive solvent penetrate into the wood. The reactive solvent is soluble in the liquid carrier and the impregnant is substantially insoluble in the liquid carrier but soluble in the reactive solvent. After the impregnant, reactive solvent and liquid carrier have penetrated the wood, the reactive solvent is reacted to become a nonsolvent for the impregnant. Since the impregnant is no longer soluble in the reacted reactive solvent, the impregnant is immobilized in the wood and, therefore, is unable to bloom. After the reaction, the liquid carrier and optionally the reacted reactive solvent are recovered from the treated wood which is clean and need not be washed.

Abstract: ABSTRACT OF THE DISCLOSURE            A transfer mechanism for transferring a large generally flat workpiece into and out of a power press, or between adjacent power presses, including a pair of spaced stands having respective gear boxes swingably mounted thereon with reversible drive means for oscillating the gear boxes in unison through 180° from a first horizontal position downwardly and then upwardly to a second horizontal position with subsequent return along the same path to the first position.   The gear boxes carry coaxial stubshafts with arms of equal length mounted thereon and with grippers at the ends of the arms for gripping the lateral edges of the workpiece.          Each of the gear boxes has an input gear which is coaxial with the oscillation axis and anchored to the associated stand as well as an output gear which is connected to the associated stubshaft, the input gear being twice the diameter of the output gear and having the same directionality so that as the gear boxes are swung from first to second position the arms are swung from a first horizontal position to a second horizontal position extending in the opposite direction, the grippers being operated cyclically and in unison for gripping and depositing a workpiece.   In one embodiment each arm has an input gear coaxial with the stubshafts and anchored with respect to the associated gear box and an output gear connected to the grippers, with the input gear being one-half the diameter of the output gear so that the workpiece maintains a constant orientation as it is being transferred.   The arms are longer than the gear boxes, as measured from center to center, so that the grippers follow a shallow arcuate path.   For achieving turnover of the workpiece the grippers are fixed to the arms.  In an alternate construction the gear box and arm oscillate in a horizontal plane.

Abstract: ABSTRACT                 A redundant microwave configuration providing a highly flexible routing of a plurality of inputs to a plurality of inputs is characterized by at least two switching layers wherein each switching layer comprises a plurality of four port switches and the switches in at least one of the switching layers are connected in a ring, corresponding switches in the layers being interconnected.  This redundancy configuration is not limited to microwave applications only but could be implemented at all other frequencies.  One microwave configuration employs 2N amplifiers between said switching layers as building blocks to provided N inputs to N antenna ports.  This configuration allows any conbination of (m-N) amplifier failures without loss of service, where N ? m ? 2N. In other configurations, only one type of switch is used and fewer than 2N amplifiers are used for N inputs and N outputs. Moreover, by properly choosing path lengths, the outputs of two or more amplifiers can be combined where greater output is required than that provided by a single amplifier.  In still other configurations, the switching layers are directly connected, and one of the switching layers comprises a matrix of fast switching elements.

Abstract: IMPROVED PHOTODIODE STRUCTURE HAVING AN ENHANCED BLUE COLOR RESPONSE     ABSTRACT OF THE DISCLOSURE          Image detectors and scanners employing n+ - p photodiodes as the photosensitive element tend to have a low blue color response relative to the red color output due to loss of photogenerated carriers near the diode surface because of surface recombination, and because of a small minority carrier lifetime due to the high doping level of the n-region relative to the acceptor doping density of the substrate.  The surface recombination and low lifetime cause loss of quantum efficiency at wave-lengths less than 4200 .ANG., which is the blue region.  An improved photo-diode is provided including a silicon p  substrate, a junction formed by a phosphorous diffusion of low doping density, and a high dose of arsenic or phosphorous ion implantation to provide a shallow implant to create a built-in electric field which repels the photogenerated minority carriers away from the surface and towards the junction to be collected.
