Abstract: IMPROVED ECONOMIZER ARRANGEMENT                       ABSTRACT This invention provides a method of removing heat from the process gas in a sulfuric acid plant having interpass and final absorption towers by indirect heat exchange with a liquid without condensing acidic vapors from said process gas.  The method comprises installing first and second economizers, the second economizer having first and second sections for liquid flow.  The process gas flows through the first econo-mizer before passing through the interpass absorption tower and through the second economizer before passing through the final absorption tower.  A liquid flows through the first and second economizers for indirect heat exchange with the process gas, the liquid passing sequentially through the second section of the second economizer, the first economizer, and the first section of the second economizer.  The second section of the second economizer is used to preheat the liquid before the liquid enters the first economizer to prevent any portion of the first economizer from cooling to the dew point of the vapors, thus preventing condensation of vapor, and to increase the heat removed from the process gas.

Abstract: FORMING MACHINE INCLUDING DRIVE MECHANISM HAVING           RACK AND GEAR SYNCHRONIZATION                       ABSTRACT           A forming machine (10) disclosed has an improved drive mechanism (28) for driving a pair of slides (20,22) mounted on upper and lower bases (12, 14) so as to provide forming of a workpiece for forming racks (24, 26) mounted on the slides. Upper and lower hydraulic motors (30,32) respectively drive the pair of slides whose movement is coordinated by a rotatable synchronizing gear (48) and upper and lower synchronizing racks (50,52). The synchronizing gear (48) is mounted by a connecting portion of the machine between the slides and is meshed with the synchronizing racks (50, 52) which are mounted on the slides by wedge adjusters (53) to adjust backlash of the synchronizing racks with the synchronizing gear. Both rotary and linear hydraulic motors for driving the slides are disclosed. A pair of tie rod connections (150) preferably extend between the upper and lower bases to control deflection therebetween during the workpiece forming. Each tie rod connection (150) includes a sleeve (152) that is compressed and a tie rod (162) that extends through the sleeve and is tensioned in a preloaded manner to provide the prevention of deflection between the bases.

Abstract: METHOD FOR REDUCING LINE WIDTH VARIATIONS IN         BILEVEL VIDEO IMAGES                            Abstract For use in a teleconference system, a method of reducing line width variations, which are assumed to be the result of undersampling of the original image.  Bilevel data received at a remote site is written into a pair of two-dimensional storage arrays.  Data stored in the first array is examined row by row to identify different length-dependent classes of black horizontal pel runs. White or black pels in the second array are overwritten with gray pels at specific pel locations as a function of run length to reduce variations in length.  The first array data is then examined on a column by column basis.  Black vertical runs are classified and the second array is overwritten with gray pels using the same rules as were applied to horizontal runs.  The trilevel second array data may be used to drive a display monitor or may first be subjected to further image processing.

Abstract: A b s t r a c t A method for joining thin-walled tubular parts (1, 2) of metal by forge/diffusion welding comprising establishing a joint (3) between opposed bounding surfaces (4, 5), the joint having increasing height from one side (7) to the other.  During heating of the parts the joint (3) is supplied with an inert or reducing flushing gas, for instance hydrogen, until the oxides are removed from the joint surfaces (4, 5). By subsecuently pressing the parts together, complete forge/diffusion welding is obtained. It is also suggested to reduce the cross-section of the parts eccentrically in the joint area and press the parts out to their initial cross-section during the forge/ diffusion welding.  A packer (8) is used to close the joint (3) on the side where the distance between the parts (1, 2) is the greatest.  Means (10, 11) are shown for performing the welding under water.

Abstract: DISTORTION COMPENSATION APPARATUS AND METHOD          Abstract Compensation for arbitrary combinations of linear and nonlinear distortion is provided by altering a received symbol value by a preselected amount.  This amount is based on an estimate of the sequence of transmitted symbol values represented by the received symbol value at a sampling time and a number of received symbol values at other sampling times.  The altered symbol value is then compared with the closest one of the possible transmitted symbol values to determine the difference, if any, therebetween. The closest one of the possible transmitted symbol values is then outputted if the difference meets a prescribed criterion.  If not, the received symbol value is altered by a different amount in response to another estimate until the recited difference meets the prescribed criterion.  In the disclosed embodiments, the foregoing technique is incorporated in a memory-based canceler or transversal filter.
