Title: Partial oxidation process for producing a stream of hot purified gas
Inventor: LEININGER THOMAS FREDERICK
IPC: C10J3/46
Filed: 1994-05-20
Granted: 2005-11-15
Abstract: A partial oxidation process for the production of a stream of hot clean gas substantially free from particulate matter, ammonia, alkali metal compounds, halides and sulfur-containing gas for use as synthesis gas, reducing gas, or fuel gas. A hydrocarbonaceous fuel comprising a solid carbonaceous fuel with or without liquid hydrocarbonaceous fuel or gaseous hydrocarbon fuel, wherein said hydrocarbonaceous fuel contains halides, alkali metal compounds, sulfur, nitrogen and inorganic ash containing components, is reacted in a gasifier by partial oxidation to produce a hot raw gas stream comprising H2, CO, CO2, H2O, CH4 NH3, HCl, HF, H2S, COS, N2, Ar, particulate matter, vapor phase alkali metal compounds, and molten slag. The hot raw gas stream from the gasifier is split into two streams which are separately deslagged, cleaned and recombined. Ammonia in the gas mixture is catalytically disproportionated into N2 and H2. The ammonia-free gas stream is then cooled and halides in the gas stream are reacted with a supplementary alkali metal compound to remove HCl and HF.      Alkali metal halides, vaporized alkali metal compounds and residual fine particulate matter are removed from the gas stream by further cooling and filtering. The sulfur-containing gases in the process gas stream are then reacted at high temperature with a regenerable sulfur-reactive mixed metal oxide sulfur sorbent material to produce a sulfided sorbent material which is then separated from the hot clean purified gas stream having a temperature of at least 1000°F.

Title: Method and circuit arrangement for the transmission of message packets according to the asynchronous transfer mode in a communication network
Inventor: GOLDNER ERNST-HEINRICH
IPC: H04L45/02
Filed: 1994-05-26
Granted: 2004-07-06
Abstract: Transmission of the message packets according to asynchronous transfer mode ensues separately on at least two completely different transmission paths having ATM switching equipment (ASW1..., ASW2...) or ATM cross-connectors (ACC1..., ACC2). An acquisition of test message packets transmitted at the transmission side and switched on the different transmission paths ensues on the basis of an interface controller unit (CCU) located at a respective subscriber of the network. Compensation is provided of the differences in running time of the message packets caused by the different transmission paths on the basis of the reception points in time. One of a plurality of identical message packets transmitted on the different transmission paths is output to a subscriber.

Title: Controlled oxygen/anti-microbial release films
Inventor: MALCHESKY PAUL S
IPC: A61L11/00
Filed: 1994-05-18
Granted: 2001-12-11
Abstract: A film for releasing at least one of an antimicrobial agent, oxygen, and a medicament includes a flexi-ble, porous layer (18) such as a wo-ven, non-woven, or knitted cloth or a layer of open cell foam.  A first dry reagent (12) and a second dry reagent (14) which react in the pres-ence of a dilutant to form the anti-microbial agent, oxygen, or medica-ment attached to the flexible, porous layer. In one preferred embodiment, the two dry reagents are disposed on opposite sides of the flexible, porous layer such that the flexible porous layer keeps the two apart and pre-vents a premature reaction.  Porous outer layers (20, 22) prevent the pow-dered reagents from being wiped off while permitting dilutant access. In a preferred embodiment, the powdered reagents include acetylsalicylic acid and a perborate which react in the presence of water to generate per-acetic acid (an antimicrobial agent which breaks down in a matter of minutes to hours into oxygen) and salicylic acid (a topical keratotic). The rate at which the reaction occurs and the peracetic acid breaks down into oxygen is controlled by buffering the pH of the pow-dered reagents, by selectively micro-encapsulating the powdered reagents, by controlling the porosity of the layers, or the like.  Optionally, surfactants, detergents, emollients, gels, and the like can be added to the dry reagents.  Alternately, a single reagent which releases oxygen or forms a strong oxidant may be used.

Abstract: Switching of traffic channels within spread spectrum beams is performed in a satellite without buffering of the individual signals. Individualsatellite beams carrying spread spectrum user RF signals from a plurality of customer premise equipments are received by radio receivers of a satellite switch and downconverted to IF signals. Traffic channel recovery is performed immediately after the down conversion and digital encoding and decoding is performed to route each channel to an appropriate outbound satellite beam. Traffic channel recovery is by despreading and filtering followed by respreading to uniquely identify each user signal so it may be recovered at its end destination. Furtherspreading uniquely identifies the user signal with an outbound satellite beam going to the intended destination of the user signal.
