Title: A method for admission control and routing by allocating network resources in network nodes
Inventor: ELWALID ANWAR
IPC: H04L12/56
Filed: 1996-07-15
Granted: 2001-03-13
Abstract: A method regulates the admission control of, and requests for routing of, virtual circuits in a network by determining network resource requirements for the virtual circuits.  In particular, the network resource requirements are based on a set of parameters used to control the flow of information from a communications device onto the virtual cirucit.  The requirements for network resources typically include buffer space requirements in network nodes and bandwidth requirements in networklinks, and the parameter used to control the flow of information are those associated with an access regulator.  The network resource determination is made for the case where lossless performance in the network is required and in the case where statistical multiplexing with limited loss is allowed. Both constant bit rate and variable bit rate information is considered.

Abstract: A method of making an integral heated nozzle using a terminal locating and sealing key. A spiral portion of an electrical heating element is press fitted into a spiral groove in the cylindrical outer surface of an elongated inner portion. The remaining outwardly extending terminal portions of the heating element are inserted through two holes in the key and the key is pushed inwardly to a position against the inner portion. The key has a pin portion which is received in a matching hole in the inner portion to exactly determine the length of the spiral portion of the heating element and accurately locates the terminal portion of the heating element. An outer collar portion having a slot in which the key is received is then mounted in place around the rear end of the inner portion.      A thermosetting ceramic sealant is applied in the space between the inner and outer collar portions then heated to integrally joint them together. The key fits in the slot in the outer collar portion to prevent leakage of the liquid sealant out through the slot.

Title: A method for selecting a preferable wireless communications service provider in a multi-service provider environment
Inventor: RAFFEL MICHAEL ALLEN
IPC: H04W24/00
Filed: 1996-10-21
Granted: 2001-05-01
Abstract: A communication device locates a preferable wireless service provider in a multi- service provider environment using a frequency band search schedule. Initially, the communications device registers with a less preferred service provider in a first frequency band. While remaining registered with the less preferred service provider, the device examines several frequency bands in the order specified by the frequency band search schedule. A frequency band is examined by dividing the frequency band into many sub- bands, and by locating the strongest signal above a threshold within the sub-band being examined. The examination continues until a second frequency band having a more preferred service provider is located. The communication device then registers with the more preferred service provider.

Abstract: A fenestrated centrifugal terminator is described for use in an internally circulating fluid bed reactor or conventional riser reactor.  It includes a tubular member having a straight vertical tubular portion the lower end of which is adapted for attachment to the upper end of a riser tube.  The upper end of the vertical tubular portion merges into a substantially semi-circular inverted U-shaped tubular loop and terminating in a downwardly directing opening.  A ramp portion of shallow angle is provided in the vertical tubular portion adjacent the inner face of the loop and terminating at the inlet to the loop to thereby create a venturi.  Commencing at the end of the ramp portion is a semi-circular divider wall dividing the tubular loop into a larger upper flow channel and a smaller lower flow channel.  This divider wall has a plurality of longitudinally spaced lateral slots through which the gas being separated from the solids is discharged.  This gas is collected in a chamber beneath the semi-circular divider wall and then discharges through a discharge outlet connected to the lower flow channel.  This terminator is capable of separating solids from gas in less than 20 milliseconds with a separation efficiency of at least 99.5%.

Abstract: A process of producing granules of a reactive metal. The process comprises providing a source of molten reactive metal (41), forming discrete droplets (53) of the molten metal, contacting the droplets while still substantially molten with a fluidized bed of particles (12) maintained at a temperature substantially below the solidus temperature of the metal and freezing the droplets as discrete granules of the reactive metal in the fluidized bed. The invention also provides apparatus for carrying out the method and product produced by the method, including a magnesium-containing additive for aluminium alloying. The use of a fluidized bed for cooling and freezing the droplets avoids problems encountered in prior methods and also makes it possible to provide coatings of various kinds on the surfaces of the granules, if desired.

Abstract: A coupon manufacturing machine assembly (10) for producing a two-sided coupon card (78). The coupon card (78) is fabricated from a continuous sheet of stock (26) wherein the sheet of stock (26) has an adhesive layer (30) and a release film (32) applied to a bottom surface (34). A printing station (12) prints indicia on a top surface (36) of the continuous sheet of stock (12) in two parallel rows. The two parallel rows define a first strip (38) and a second strip (40) of the stock (26). A laminating device (14) applies a clear laminate (46) to the top surface (36) of the stock (26) for viewing the indicia. A cutting device (16) separates the continuous sheet of stock (26) into the first strip (38) and the second strip (40) and an inverting device (18) rotates the second strip (40) 180° relative to the first strip (38). More specifically, the second strip (40) passes through a first turn bar (52), a spacing roller (58), and then through a second turn bar (54) to effectuate the 180° rotation. A striping device (20) removes the release film (32) from the first strip (38) to expose the adhesive layer (30). The adhesive layer (30) of the first strip (38) is moved into a bonded relationship with the release film (32) of the second strip (40). Specifically, a coupling device (22) mates and adheres the adhesive layer (30) of the first strip (38) with the release film (32) of the second strip (40) to form a series of two-sided coupon cards (78) with the indicia printed on both sides thereof.

Title: Procede de preparation de peaux ou de fourrures animales
Inventor: WEIDNER ECKHARD
IPC: C14C1/04
Filed: 1996-03-01
Granted: 2007-07-10
Abstract: Afin d'obtenir un procédé de préparation de peaux ou de fourrures animales moins laborieux et plus respectant mieux l'environnement, on traite les peaux ou les fourrures animales après une trempe classique dans une solution classique de tannage dans laquelle du dioxyde de carbone est dissous sous pression. On peut ainsi réduire considérablement le temps habituellement nécessaire pour obtenir des cuirs ou des fourrures, étant donné que leur durée de traitement est sensiblement réduite. On peut en outre de cette façon réunir plusieurs étapes classiques de traitement en une seule étape de traitement. Au lieu des 20 à 40 tonnes d'eaux usées habituellement produites par tonne de cuir ou de peaux dans les procédés classiques, seulement 2 tonnes environ d'eaux usées sont produites par tonne de cuir ou de peaux. Ce procédé a non seulement un impact sensiblement réduit sur l'environnement, par rapport aux procédés classiques, mais il est aussi beaucoup plus économique, compte tenu de la réduction considérable de la durée totale de traitement.

IPC: H04Q7/22
Filed: 1996-11-22
Granted: 1999-12-14
Abstract: A method for transmitting packetized data in a cellular communication system uses a dynamic channel assignment scheme. In this aspect of the invention a data control channel is used in addition to the data traffic channel. The mobile end system uses the data control channel to send a request for assignment of a channel for transmission of data - such as a particular frequency/time-slot in a TDMA system. The network responds with the identification of a particular channel that may be used for a particular time period to transmit data. In this aspect of the invention there is no dedicated channel that is used for data transmission. Rather, the network determines a channel that will be free for the specified time period and assigns it for data transmission.

Title: Annealing magnetic elements for stable mechanical properties
Inventor: GADONNIEX DENNIS MICHAEL
IPC: G08B13/22
Filed: 1997-06-25
Granted: 2009-04-28
Abstract: A control element for a magnetomechanical EAS marker is formed by annealing an amorphous metalloid (20) so as to be at least partially crystallized while remaining substantially flat. Preferably a two-stage process is applied to induce semi-hard magnetic characteristics in an amorphous metallic material (20) that is magnetically soft as cast. In a first stage (26), the material is annealed for at least one hour at a temperature below a crystallization temperature of the material. This produces a reduction in volume of the material. The second stage (30) is carried out at a temperature above the crystallization temperature for a time sufficient to crystallize the bulk of the material and give it semi-hard magnetic properties. The two-stage annealing process prevents deformation of the material which has resulted from conventional crystallization processes.
