Title: Method and apparatus for communicating digital information words by error-correction encoding
IPC: G11B20/18
Filed: 1981-09-15
Abstract: A method and appratus are provided for communicating a sequence of digital information words. The information words are separated into a sequence of odd information words and a sequence of even information words. The separated odd and even information words are time-displaced from each other by a predetermined amount. The odd information words are encoded in an error-correcting code, and the even information words are separately encoded in a similar error-correcting code. The encoded time-displaced odd and even information words are combined into a transmission block, and this transmission block is transmitted or recorded. In one embodiment, the information words are encoded by generating an error-correcting word in response to the odd information words and by generating an error-correcting word in response to the even information words. The respective error-correcting words are interleaved with the odd and even information words. To recover the original information words, the transmission block is received and the odd and even information words are decoded so as to correct errors therein. The time displacement between the decoded off and even information words are removed. If an information word contains an uncorrected error therein, a correct information word is approximated therefor by interpolating adjacent decoded odd or even information words so as to approximate a correct even or odd information word, respectively. A corrected sequence of information words formed of the decoded and approximated information words is recovered.

Title: A heat exchanger
IPC: F28G15/02
Filed: 1983-06-25
Abstract: A heat exchanger has a plurality of fluid-circulation tubes fixed together at their ends with tube sheets. The cleaning elements are adapted in order to move backwards and forwards in the tubes and to be captured by longitudinal boxes. A longitudinal-box retention plate is mounted securely, for example, with bolts or the like, next to and, in one embodiment, in a spaced relationship outside, the outer face of the tube sheet. The plate and its mounting interact with the tube sheet in order to secure the longitudinal boxes in a fixed position in relation to the tube sheet and the ends of the tubes. The outer capture and securing portions of the longitudinal boxes extend beyond the retention plate. The longitudinal boxes include central or intermediate portions which pass through the openings in the plate and inner portions which pass through the space between the plate and the tube sheet and which end inside the openings in the tube sheet. The longitudinal boxes are secured firmly, so that they are unable to move transversly, with a support having two points, one on the inner ends of the longitudinal boxes and another between their ends. In order to secure the longitudinal boxes in a longitudinally fixed position and, in one embodiment, the longitudinal-box intermediate portions, they are screwed to the retention plate. In another embodiment, the projections adjacent to the inner ends of the longitudinal boxes connect the plate and the tube sheet. The retention plate has a smaller diameter than the tube sheet and is equipped with fluid-circulation openings without obstacles between the longitudinal boxes and the longitudinal-box reception openings.
