Abstract: A method and an apparatus for the manufacture of heat-exchanger rolls (10). The roll (10) consists of two webs (12, 14) of material which are wound together in superposed relationship. One (12) of the webs is corrugated and formed with protrusions/dents at the crests and bottoms of the corrugations. The second web (14) is provided with lengthwise ribs having the same configuration as the protrusion/dents. When the webs (12, 14) are wound into a roll (10) a radial pressure is exerted on the wheel (10) in order to press the ribs efficiently into the protrusions/dents and to achieve efficient and safe interconnection of the various winding turns making up the roll (10). To impart a tension in said webs (12, 14) a retarding (braking) force is applied thereon during the winding-on of the webs.   The invention also comprises an apparatus for performing the method, the pressure and braking force on said webs being exerted by a pressure roller (56).

Abstract: The compression of successive blocks of digital data is optimized by selecting between different compression algorithms or different data formats on a block-by-block basis. In one application, digitized interlaced video signals are processed for transmission in a compressed form. A set of pixel data presented in a field format is compressed to provide a first compressed video signal. The set of pixel data is also presented in a frame format and compressed to provide a second compressed video signal. Errors are evaluated in the first and second compressed video signals. The compressed video signal having the least error is selected for further processing. The technique is repeated for successive sets of pixel data and the selected signals are encoded to identify them as field formatted or frame formatted signals. The encoded selected signals are then combined to provide a compressed video signal data stream for transmission. Apparatus for receiving and decoding the signals is also disclosed. <IMAGE>

Abstract: A vertical tubular reactor for converting ammonia synthesis loop purge gas to ammonia; a method for converting ammonia synthesis loop purge gas to form additional ammonia; and a method for retrofitting a conventional ammonia plant having a synthesis loop using an iron-based synthesis catalyst and having a purge gas stream, the method including a supplemental ammonia converter for the purge gas stream. The supplemental ammonia converter is a shell and tube reactor. The tubes are filled with a catalyst comprising a platinum group metal such as ruthenium. The tubes are maintained in a substantially isothermal condition by boiling water in the shell side. As a retrofit modification to an existing ammonia synthesis plant, the purge stream is passed through the supplemental ammonia converter on a once-through basis to form additional ammonia and reduce the amount of purge gas. Advantages of the retrofit modification include lower energy consumption, lower purge rates and higher ammonia production rates. <IMAGE>
