摘要： A computer network encryption/decryption device includes at least one microprocessor, microprocessor support hardware, at least two network ports for connecting to upstream and downstream networks, memory hardware for storing program, configuration, and keylist data, and data encryption/decryption hardware. The device operates in one of two modes by selectively encrypting or decrypting packets or portions of packets based on information contained in a packer's header.

摘要： A cleaning system for dislodging dust from the filter bags of a dust filter having dirty and clean air plenums separated by a tube sheet. The tube sheet is divided into segments each having filter bag openings arranged in the same pattern. An air accumulator tank which continuously receives compressed air is rotated in the clean air plenum with a connected distribution arm which applies air pulses to the filter bags through discharge nozzles arranged in the same pattern as the filter bag openings. A position sensor allows cleaning air in the tank to be applied to the distribution arm only when the arm is aligned above a segment with all nozzles centered on the filter bags. A quick acting diaphragm valve is combined with the air tank to control air flow into the distribution arm at a location adjacent to the arm to minimize the response time.

摘要： An electrochromic cell is provided having a Li.sup.+ doped oxymethylene-polyoxyethylene solid polymer electrolyte. The film of ionically doped oxymethylene-polyoxyethylene is sandwiched between two complementary electrochromic layers, one of which is tungsten oxide. The other electrochromic layer is a polyaniline or a Prussian Blue material. The complementary electrochromic layers are deposited onto electrically conductive transparent substrates, such as fluorine-doped tin oxide coated glass. The electrochromic cell colors and bleaches by the application of an appropriate electrical potential between the two electrochromic films. The Li.sup.+ doped oxymethylene-polyoxyethylene electrolyte is stable at elevated temperatures up to about 100.degree. C.

摘要： A method of removing particulates and sulfur oxides from a hot gas by controllably contacting the hot gas in a first spray-dryer zone with a selected chemically reactive absorbent for the sulfur oxides and then sequentially contacting the hot gas with the absorbent in a second fabric filter zone. The preferred absorbents are calcium oxide, calcium hydroxide, sodium carbonate, sodium bicarbonate and sodium hydroxide. The selected absorbent dissolved or dispersed in an aqueous medium is controllably introduced into the spray dryer, together with the hot gas, in an amount and at a rate to react in the spray dryer with only a portion of the sulfur oxides in the hot gas to produce a dry particulate reaction product consisting of calcium or sodium sulfites and sulfates, together with sufficient unreacted absorbent of enhanced reactivity for subsequent reaction in the second zone with the remaining sulfur oxides, all being entrained in a substantially water-unsaturated gas of reduced sulfur oxide content. This resultant gas containing the dry particulate reaction product and unreacted absorbent is transferred into the second zone where it is directly impinged upon an upstream surface of a gas-permeable porous fabric so that a substantially uniform coating of the dry particulate product and unreacted absorbent is formed and maintained, under steady-state conditions, on the upstream surface of the fabric. Further reaction occurs in this second fabric filter zone between the absorbent, which has enhanced reactivity, and the sulfur oxides present in the gas passing through the fabric filter so that the gas exiting from the downstream surface of the fabric is substantially free of particulate matter and has a substantially reduced sulfur oxide content.

摘要： Non-sintered PTFE-bound electrodes for alkaline storage batteries are made by coagulating polytetrafluoroethylene (i.e. PTFE) particles from an aqueous dispersion thereof to form a gelatinous coagulum, mechanically dispersing the coagulum in water such that the coagulum is subdivided into small, sticky clots of PTFE particles which are suspended in the water, mixing the suspension with comminuted electrochemically active material to form a slurry of active material and active-material-coated clots, filtering the slurry to separate the solids (i.e. as a filter cake) therefrom, integrating (e.g. sandwiching) an electrically conductive current collector with the filter cake, compressing the thusly formed composite, and drying the compress.

摘要： A computer network encryption/decryption device includes at least one microprocessor, microprocessor support hardware, at least two network ports for connecting to upstream and downstream networks, memory hardware for storing program, configuration, and keylist data, and data encryption/decryption hardware. Both network ports have the same network address, making the device transparent to the local area network in which it is spliced. The device operates by selectively encrypting or decrypting only the data portion of a data packet, leaving the routing information contained in the header and trailer portions of the data packet unchanged.
