Abstract: A distributed parallel processing architecture (10) for electronically steerable multi-element RF array antennas provides real time rapid array updates with decreased hardware cost and complexity. The array is subdivided into plural sub-arrays (34) (each sub-array has more than one RF radiating element) and a phase shift interface electronics ("PIE") device (30) is provided for each sub-array. Parameters specific to the RF elements within the sub-arrays (34) are preloaded into the corresponding PIE (30). Pointing angle and rotational orientation parameters are broadcasted to the PIEs (30), which then calculate, in parallel and in a distributed processing manner, the phase shifts associated with the various elements in their corresponding sub-arrays. Linearization, phase compensation for various factors (e.g., operating frequency, measured characteristics of individual RF elements, feed line delay to individual elements, etc.), and the initial phase shift calculations themselves are thus performed on essentially an element-by-element basis without requiring individual calculation hardware for each element. Array spoiling in response to real time array rotational orientation is provided. Update rates of greater than 10KHz are attainable.

Inventor: MACH HORST-ROLAND
IPC: D06P3/68
Filed: 1989-12-06
Abstract: In the conventional diazotization of fast colour bases or fast colour salts with subsequent neutralization of the acid present using Na acetate, reactive dyes can only be fixed incompletely in the print alongside diazo compounds of this type on alkali-preimpregnated goods in a one-phase process, since the acid vapours escaping in the steam partially neutralize the alkali. For this reason, it was necessary to use the two-phase procedure under these circumstances. These disadvantages can be overcome according to the invention if amines intended for dye coupling are diazotized with non-steam- volatile acids, and the pH adjustment (neutralization) is effected using salts of medium-strength, non-steam-volatile acids. Reactive dyes can then be printed onto alkali-preimpregnated goods in one phase alongside diazonium compounds and fixed without losses in the steam.

Abstract: An aromatic hydrocarbon is bromoethylated to a 1-bromo-1-arylethane with minimal co-formation of diaryl­alkane by-product by reacting it with hydrogen bromide and acetaldehyde at a temperature in the range of +10°C to -35°C in the presence of at least about one mol of hydro­gen sulfate per mol of the aromatic hydrocarbon and in the absence of more than bout 15% by weight of water, based on the weight of the hydrogen sulfate. The process is of particular advantage in the bromoethylation of the less reactive aromatic hydrocarbons, such as isobutylbenzene and other monoalkylaromatic hydrocarbons, which have previously yielded an undesirable amount of diarylalkane when bromoethylated with acetaldehyde and hydrogen bromide.

Abstract: A process is claimed for removing, by evaporation, waste waters of oil mills, obtd. by using, in a dessication plant, spent olive marc imbibed with these waters, of the type where vegetation water is sprinkled on the marc to be introduced into a hot air cyclone of a dessication plant where the water evaporates and the solid parts in suspension deposit on the above mentioned marc, this marc being again sprinkled with vegetation water and reintroduced into the plant and so on until complete evaporation of the water. The novelty is that the olive marc used for introducing the vegetation water which must be evaporated in the hot air cyclone is spent marc, i.e. marc which has already undergone the process of extraction of oily residues by degreasing.

Abstract: Fail information from testing of a DUT memory array is captured and compressed by utilizing a compression matrix which is related in size to the available redundancy associated with the DUT (device under test) memory array, and which, in essence, defines the limits of redundancy repair. The compression matrix includes a plurality of matrix cells fewer in number than the number of memory cells in the DUT memory array and is arranged in a matrix of compression rows and compression columns. The compression matrix is loaded with the fail information concurrently with testing of the DUT memory array. There are also provided column and row selects for storing, and assigning to each compression column or row of at least a portion of the compression columns and rows, a different column or row-address portion of the fail information, and for providing selection of compression columns and rows according to stored column and row address portions. Comparators compare, for each compression and column, a count of matrix cells set along each column and row to a predetermined redundancy value, and, when the count becomes greater than the redundancy value, there is a designation of a memory array column or row as a "must fix", and there is a blockage of storage of row-address or column-address portions, respectively, of fail information having the same column-address or row-address portion as that of the column or row that has been designated as a "must fix".
