Title: Access control method in communication system
Inventor: OHMI SHINICHIRO
IPC: H04L69/14
Filed: 1997-05-27
Abstract: A down-link frame generating/transferring portion 12 detects a free channel from among a plurality of previously assigned up-link channels. The down-link frame generating/transferring portion 12 selects a secondary station 2 to which the free channel is to be assigned by referring to an address table 11 every time it detects a free channel. Then the down-link frame generating/transferring portion 12 sends out onto a down-link channel a down-link frame in which the secondary station address of the selected secondary station is set in an address slot corresponding to the free channel.

Title: Continuous interference assessment and avoidance in a land mobile radio system
Inventor: DYE DAVID A
IPC: H04B7/26
Filed: 1997-10-28
Abstract: In a land mobile radio system including at least one base site having a system for interconnecting a plurality of radio channel units with a plurality of directional antennas and/or antenna beams, the base site further includes interference avoidance means for controlling communications between each radio channel unit of the base site and mobile radio units communicating with the base site so as to avoid causing potential interference at the operating frequency of each radio channel unit at other base sites.  The interference avoidance means includes means for monitoring potential interference at the operating frequency of each radio channel unit on each antenna beam.  If potential interference exists on an antenna beam determined to be the antenna beam best suited for transmitting and receiving signals at the operating frequency of the radio channel unit, a determination is made if adjacent antenna beams have reduced chance of potential interference and sufficient signal strength for communication and therefore are better suited for transmitting signals at the operating frequency of the radio channel unit.  To further enhance interference avoidance, a comparison is made of the signal strength of received signals at the operating frequency of the radio channel unit with one or more threshold values to assess the proximity of the mobile radio unit to the base site, and the transmission signal strength for signals transmitted from the radio channel unit to the mobile radio unit are controlled based on the proximity assessment.

Title: Non-contact heat absorbers for strip casting
Inventor: MAHAPATRA RAMA BALLAV
IPC: B22D11/10
Filed: 1997-03-06
Abstract: A method and apparatus for casting ferrous metal strip. A casting pool (30) of ferrous molten metal is supported on a pair of chilled generally horizontal casting rolls (22) forming a nip (27) between them. The casting rolls (22) rotate mutually opposite directions to produce a solidified metal strip (12) moving downwardly from the nip (27). The strip (12) passes along a transit path (10) which takes it away from the nip (27) in an unrestrained loop (29) disposed within a strip enclosure (38) within which the strip is confined through said transit path (10). The strip (12) moves downwardly from the nip (27) to form the unrestrained loop (29) passes between a pair of cooled non-contact heat absorbers (101) to which heat is radiated from the strip (12) whereby to extract from the strip heat generated by completion of solidification of metal therein after leaving the casting pool (30). Heat absorbers (101) are formed as opposite side walls of a cooling collar (100) defining an upper part of enclosure (38) and provided with cooling water ducts (102).

Title: Use of di-beta-d-glucopyranosylamine compounds for controlling inflammatory reactions, and method of synthesis
Inventor: DRUBE CLAIRMONT G
IPC: A61K9/08
Filed: 1996-06-06
Abstract: Adverse inflammatory reactions can be treated by administrating to an organism a composition having diglucosylamine as the active ingredient. The preferred compound is di-Beta-D-glucopyranosylamine. A simple method for making diglucosylamine in high purity is obtained by reacting glucose, a nitrogen containing base, and either methanol or ethanol to form the diglucosylamine and then recovering the diglucosylamine preferably with the use of charcoal. The preferred diglucosylamine, di-Beta-D-glucopyranosylamine, has extraordinary anti-inflammatory activity. It can be formulated with a pharmaceutically acceptable carrier to make pharmaceutical compositions which are effective in treating inflammations. This pharmaceutical composition can also be used to treat adverse inflammatory reactions that are the result of the disruptions of a dynamic network of cellular mechanisms in organisms. In addition, application of this composition also serves to reestablish the balance of the cellular defense network in an organism which has its cellular defense network out of balance. In this unbalanced case, the composition serves to treat the pathology of inflammation and activates the inflammatory control system in vivo. These adverse inflammatory reactions can also be treated by administrating to the organism glucose in the presence of NH3+ ions and at a pH of about 7.0 or greater. The glucose can preferably be applied by orally administrating an enteric-coated form of glucose, alone or in combination with other medicaments.

Cette connexion par chevauchement et à soudure par diffusion possède une couche dure de diffusion (7) d'une épaisseur n'excédant pas 5 µm. Dans la zone de chevauchement, les manchons possèdent des parois d'une épaisseur variable, de sorte que l'épaisseur de la paroi d'un manchon diminue tandis que l'autre augmente proportionnellement, par exemple par paliers, les protubérances et les renfoncements étant de forme annulaire. Ce raccord peut être utilisé dans le domaine du nucléaire et dans l'industrie chimique en qualité d'insert bimétallique lors de la soudure de tubes en acier inoxydable à des tubes en alliages de zirconium.

Title: Process for the desulphurization of gaseous substrate
Inventor: SCHOUBYE PETER
IPC: C01B17/765
Filed: 1997-12-29
Abstract: A process is provided herein for the desulphurisation of a gaseous substrate containing O2, SO2, SO3, H2, SO4, H2S, CS2, COS and/or organic sulphur-containing components. The process includes the first step of adjusting the water content in the feed gas to provide sufficient water for the production of H2SO4. The feed gas is passed into a first of two serially-arranged catalytic heat exchange reactors. Each of the catalytic heat exchange reactors contains a catalyst unit which is disposed over a heat exchange unit, so that the feed gas absorbs heat from the heat exchange unit and passes into the catalyst unit, where components in the feed gas are catalytically oxidized into SO2, H2O and CO2 at a temperature in the range of 300-500°C, and thereby to provide an oxidized feed gas. The oxidized feed gas is discharged from the first of the two catalytic heat exchange reactors. The oxidized feed gas is then injected into the second catalytic heat exchange reactor. The oxidized feed gas passes through the second of the two catalytic heat exchanger reactors and residual amounts of SO2 are oxidized into SO3 at a range of 300-500°C. This provides a S03-containing feed gas. The SO3-containing feed gas is passed into a heat exchange unit within the second catalytic heat exchange reactor where the SO3-containing feed gas is cooled and water within the feed gas hydrolyses the SO3 into H2SO4, which is condensed and removed from the second catalytic heat exchange reactor. This provides treated gas.      The treated gas from the second catalytic heat exchange reactor is discharged at a temperature that is at least 50°C below the H2SO4 dew point of the process gas after oxidation of the sulphur content in the feed gas. The direction of the flow of the feed gas is cyclically changed, after a period of 1 to 40 minutes, so that a feed gas is injected into a catalytic heat exchange reactor from which the treated gas was discharged in the previous cycle, and first passes through a heat exchange unit in that catalytic heat exchange reactor.
