Title: Method and apparatus for determining the average size of apertures in an apertured member
IPC: G01B11/14

Title: Separation device for vapours from low-boiling liquefied gases, evolved during their transfer.
IPC: F17C6/00
Filed: 1978-09-15
Abstract: During the delivery of low-boiling liquefied gases in pipelines, a two-phase flow of gas and liquid forms, since some gas constantly vaporises through the incidence of heat. The vaporised gas can be separated in phase separators which essentially consist of an insulated container (1) having a feed line (3) for the low-boiling liquefied gas and discharge lines (10, 12) for the separated gaseous and remaining liquid gas. The liquid phase occurs here in liquid droplets of the most varied size. The smaller drops are partly entrained with the gas phase, which is tantamount to a loss of liquid phase. The insulated containers are therefore designed to be as large as possible in order to achieve low gas velocities. A large type of construction of the insulated containers is avoided by the feed line for the low-boiling liquefied gas in the container leading into a porous hollow body (4). Liquid comes out of the porous hollow body in the form of uniform, large drops.

Title: Method of error correction
IPC: H03M13/27
Filed: 1981-06-17
Abstract: A method of receiving and decoding doubly-encoded, interleaved data occurring in blocks of information words and first and second check words to correct errors occurring due to transmission, includes adding error pointers to indicate uncorrectable errors, and thereafter checking the number of pointers in each block and protecting against miscorrection of errors. The data are decoded in a first decoder and the information words and first check words are corrected by syndromes using the second check words. A pointer is added to any words containing uncorrectable error. Then the words so decoded are deinterleaved and decoded in a second decoder, where the information words are corrected by syndromes using the first check words. Here the pointers show the position of any erroneous words to facilitate error correction. The number and location of erroneous words in each block, at the second decoder, is determined by using the error syndromes. If the erroneous word locations as determined by the syndromes is coincident with the locations indicated by the associated pointers, the erroneous words, up to the predetermined number, are corrected. Finally, uncorrected erroneous words are compensated by interpolation.

Title: Hot gas particulate removal.
IPC: B01D46/10
Filed: 1981-09-29
Abstract: Filtration system configurations particularly useful for cleaning high temperature raw gas containing fine particulates such as that discharged from coal gasification and fluidized bed combustion processes.

The elements are cleaned by a back pulse of clean air, spitting the particulates to the bottom of the containing vessel and through an outlet. A high density filter packing within a containing pressure vessel is achieved by nesting a plurality of the duct and filter element modules, or through other orientations and filter element configurations.
