Title: Method and apparatus for initializing secure communications among, and for exclusively pairing wireless devices
Inventor: PETERS MARCIA LAMBERT
IPC: G06F21/44
Filed: 2000-05-22
Abstract: A method and system for efficiently establishing secure communications between mobile devices in a radio network. The present invention utilizes public key cryptography and unique hardware identifiers to enable authorizations for access to wireless networks, such as picocells. The present invention prevents the mobile user from maintaining a plurality of secrets such as user identifier/password pairs, PINs, or encryption keys, for access to each device to which he might require access. Wireless devices distributed throughout an enterprise are enabled to be efficiently initialized for secure communications. Well-known public key cryptography and machine unique identifiers are utilised to establish a secure channel and initialize the wireless devices. Wireless devices are enabled to be paired or permanently associated by a user or a network administrator. Well known public key cryptography and machine unique identifiers are utilised to establish a secure channel and associate the devices with each other. This is extremely useful for associating a wireless headset with a telephone or associating a wireless mouse with a computer.

Title: Dispositif de fermeture de recipient
Inventor: SHOWERING FRANCIS
IPC: B65D43/02
Filed: 2000-05-09
Abstract: Cette invention concerne un dispositif de fermeture de récipient à ajustement serré (14) comprenant une pluralité de pattes de fixations (20) segmentées dépendantes dotées de projections à encliqueter destinées à s'emboîter en-dessous du bord de l'ouverture du récipient. Une bande monobloc (30) est reliée aux pattes de fixation afin de fermer solidement l'ouverture du récipient avec le dispositif de fermeture (14). Le retrait du dispositif de fermeture (14) s'effectue par soulèvement de la bande (30) vers l'extérieur (pivotement vers le haut). Les pattes de fixation (20) peuvent alors se plier vers l'extérieur, permettant ainsi au dispositif de fermeture (14) d'être soulevé et retiré de l'ouverture du récipient. La bande (30) peut être fixée aux pattes de fixation (34) par des éléments de liaison destructibles (34) fournissant au récipient une caractéristique d'inviolabilité. Une ou plusieurs pattes de fixation (20a) peuvent être conçues pour être désengagées avant les autres pattes de fixation lors de l'ouverture, afin de compenser la pression interne qui règne dans le récipient alors que les pattes de fixation qui restent engagées maintiennent le dispositif de fermeture solidement fermé et empêchent ainsi les projections qu'il pourrait provoquer par l'ouverture du récipient.

IPC: H02J5/00
Filed: 2000-09-06
Abstract: A series resonant inductive pickup has a bi-directional solid state switch (203) in series with an inductor (W) and a capacitor (202) is controlled by switch control means (207) capable of causing the switching means to repetitively be in either an open or a closed state, so that by varying the closed:open ratio of the switch (203) the time-averaged amount of power picked up by the power pickup can be controlled. Switch (203) is controlled by output (214) of a voltage comparing circuit (212). A reference voltage source (213) provides a basis for comparison of some fraction of a supply voltage (208) in order to cause the switch to operate. The magnitude of capacitance (D) in relation to the current (I o) drawn by the load (L) determines the repetition rate of ON or OFF commands to the switch (203). If the current (I o) drawn by the load (L) tends to zero, the proportion of time during which the switch (203) is open will tend to 100 %.

Title: Process for the production of sulfur
Inventor: GOAR B GENE
IPC: C01B17/60
Filed: 2000-10-20
Abstract: A process is provided for producing elemental sulfur from hydrogen sulfide contained in an acid gas feed stream wherein hydrogen sulfide and sulfur dioxide are reacted in a catalytic only sulfur recovery unit comprising a single catalytic converter containing a Claus catalytic reaction zone. A sulfur dioxide-enriched gas recovered from tail gas treatment is recycled and introduced into the catalytic reaction zone as part of a feed gas mixture that also includes the acid gas feed stream. Temperatures within the catalytic reaction zone are effectively moderated by recycle of tail gas effluent to the converter so that high concentrations of hydrogen sulfide in the acid gas feed stream can he tolerated and improved process flexibility and capacity are realized. A pretreatment process including contacting the acid gas with an aqueous acid wash to reduce the concentration of unsaturated hydrocarbons in the acid gas and inhibit deactivation of the oxidation catalyst is also disclosed.

IPC: B23D45/06
Filed: 2002-06-26
Abstract: A table saw includes a work support table that defines a blade slot therethrough and at least one guide groove oriented generally parallel to the slot. A pair of trunnions are attached to the lower surface of the work support table, with at least one of the trunnions defining an adjustment opening having opposing sides. A cradle assembly has a blade mounted therein driven by a motor, and it is supported by the trunnions such that at least a portion of the blade extends through the slot in the work support surface. To provide adjustment of the blade heel, an adjustment member is received by the adjustment opening in the trunnion and is rotatably attached to the lower surface of the work support table. Rotation of fine adjustment member causes the adjustment member to contact one of the opposing sides of the adjustment opening, thus moving the trunnion to adjust the position of the blade relative to the guide groove.

Title: Enhancements in pulping with dissolved solids control
Inventor: LUHRMANN CARL L
IPC: D21C3/24
Filed: 1995-06-01
Abstract: The sulfide ion concentration and sulfidity of kraft cooking liquor during kraft cooking of cellulose pulp is selectively increased. After treatment in a first treatment zone in which impregnation or kraft cooking takes place using a kraft cooking liquor having a first sulfide ion concentration and sulfidity, black liquor is extracted from the material, liquid is withdrawn from the material and dilution liquid is added to the withdrawn liquid and the withdrawn liquid with dilution liquid is reintroduced. In a second treatment zone after the first zone a second kraft cooking liquor is introduced having a second sulfide ion concentration and sulfidity greater than the first sulfide ion concentration and sulfidity (typically by about 20-50%), including by manipulating controlling the flow rate of extraction and the flow rates of withdrawal of liquid and addition of dilution liquid.  The pressure of the continuous digester is controlled in a unique manner that avoids disruptions to the column of pulp continuously moving downwardly in the digester, anywhere in the digester, but particularly avoids non-uniform, unstable material in the countercurrent washing zone. The pressure is controlled by withdrawing liquid from, and introducing liquor into, the digester at at least one additional extraction-dilution loop aside from the main extraction of the digester and the wash dilution liquid introduction mechanism below the wash screens. Pressure can also be maintained (e.g, at about 130-170 psi) by also controlling the amount of wash dilution liquor, and by varying the extraction flow.

Abstract: A system and method in a General Packet Radio Service (GPRS) network for automatically configuring Network Service Entity Identifiers (NSEIs) in a Base Station System (BSS(32)) and a Serving GPRS Support Node (SGSN(33)) when the BSS is reconfigured. The Gb interface between the BSS and the SGSN is modified to operate using the Internet Protocol (IP), and the BSS and the SGSN are configured to run on IP.  Whenever a new Network Service Entity (NSE) is added (57) to an existing BSS. or a new BSS is added to the network, the BSS automatically sends (52) a modified Network Service (NS')-Reset message to the SGSN requesting an NSEI. The SGSN dynamically allocates (53) a tree NSEI from a pool of NSEIs and sends (54) it to the BSS. When an NSE is removed (61) from the BSS. the BSS automatically sends (62) a modified NS'-Reset message to the SGSN to free an NSEI. The SGSN de-allocates (63) the NSEI, and returns the NSEI to the pool of free NSEIs. All related entries for Base Station Systems GPRS Protocol (BSSGP) Virtual Circuit Identifiers (BVCIs) under the de-allocated NSEI are also removed by the SGSN.
