Abstract: An improved method and apparatus for transmitting data between a transceiver (10) and transcoder (15) pair of a cellular radio system is disclosed. A pair of transceiver-transcoder-links (40) normally transmitted on two separate channels are broken into a series of four bit data segments (45) which are multiplexed together into series of eight bit timeslots (50) for transmission between a transceiver (10) and a transcoder (15) pair.

Abstract: L'invention concerne des remèdes contre la toxicomanie renfermant, comme ingrédient actif, des agonistes des récepteurs  kappa -opioïdes que caractérisent les composés représentés par la formule générale (I). Ces agonistes des récepteurs  kappa -opioïdes sont utiles comme remèdes contre la toxicomanie; leurs effets secondaires sont réduits et ils agissent sur le mécanisme d'expression à effet de récompense de manière à inhiber simultanément l'expression de la dépendance psychique et physique, méthode qui diffère de la thérapie symptomatique que l'on emploie généralement pour le traitement de la toxicomanie.

Abstract: A whipstock (10) has a flowchannel (41) therethrough to facilitate the rapid lowering of the whipstock through liquid in an oil well. A whipstock (10) has a guide surface and a sacrificial element (20) spaced from the guide surface. In use, the sacrificial surface prevents the starting mill damaging the guide surface during the formation of the initial opening in a casing. The undamaged guide surface can later be used for accurately guiding tubulars and tools to help ensure that lateral bores are correctly positioned.

Title: Compositions de conservateurs pour champignons et procedes correspondants
Inventor: DUNCAN ERIC M
IPC: A23B7/04
Filed: 1998-10-02
Granted: 2007-01-16
Abstract: La présente invention concerne des compositions de conservateurs employant des ingrédients toxicologiquement acceptables, et utilisant un pH d'au moins 9,0 pendant une partie au moins du processus. On cherche ainsi à lutter contre la croissance des bactéries de dégradation, et à prévenir les changements indésirables de couleur des champignons frais et des champignons travaillés. On prépare à cet effet des solutions aqueuses que l'on applique de façon répétée sur les champignons, par pulvérisation ou par immersion. L'invention concerne plus spécifiquement un procédé de conservation des champignons frais et des champignons travaillés. Ce procédé consiste d'abord mettre les champignons en contact avec une solution tampon dont le pH est compris entre 9,5 et 11,0 environ. Le procédé consiste ensuite à rincer les champignons une ou plusieurs fois immédiatement après l'opération de mise en contact. On utilise pour cela des solutions tampon de neutralisation du pH. Ces solutions sont des solutions d'acide érythorbique et d'érythorbate de sodium, dans des rapports d'environ 1:4, et d'un pH suffisant pour ramener les champignons au pH physiologique des champignons qui se situe aux environs de 6,5.

Title: Printer mailboxing system with automatic variable capacity bins
Inventor: FERRARA JOSEPH J
IPC: B65H39/11
Filed: 1999-09-03
Granted: 2004-05-18
Abstract: In a mailboxing system in which the different numbers and types of printed sheets being printed by the different users of a shared users printer are separately stored in different assigned mailbox bins in an array of mailbox bins, there is provided a system for automatically changing the spacing between selected adjacent bins to provide selectably different sheet stacking capacities for different bins for the different numbers of printed sheets being stored in the respective bins of different users. With this system the bin capacity can also be automatically reduced when the sheets are removed from that bin. Greatly increased overall and individual bin sheet stacking capacity is thus provided for the same overall system size as compared to conventional fixed spacing bins. Also, many more print jobs can be stored in the same user-assigned bin instead of having to split up large print jobs into other, overflow, bins. A simple split (dual independently rotated sections) auger bin movement system can provide the automatic bin repositioning for the selectable variable bin capacity.

Abstract: An economical means of safely "containing" or "packaging" commercial electrophilic fluorination agents whereby these agents are readily stored and transported in a package, typically without loss of "F+" activity, and in a form which is readily and directly useable, i.e., in solution or a slurry. Importantly, the solution/slurry medium provides a tremendous safety margin for storage and transportation since the solution medium has an enormous ability to absorb heat (due to the latent heat of vaporization of the liquid) relative to the contained active fluorination agent.

Granted: 2004-11-09
Abstract: Methods and apparatus for making directional measurements of earth formations surrounding a borehole. New antenna coil shield designs are utilized to provide selective attenuation of at least one electromagnetic energy field component as the component interacts with the shield. The new shields are implemented in several downhole tool configurations to provide azimuthally focused formation measurements. In effect, the new shield filters interacting electromagnetic energy field components to pass those components corresponding to a magnetic dipole oriented at an angle from the tool axis. The shields thereby alter a coil's envelope of influence to electromagnetic energy. The new shields also form part of a system for making directional measurements while drilling.

Abstract: A process for the removal of organic impurities in a Bayer process liquor in which wet and dry oxidation process are linked together in a complementary way, such that the weaknesses of each individual organic removal process become a strength of the combined process. An organics-rich liquor stream (10), such as a spent Bayer liquor, is fed to a wet oxidation process (12) to produce a first processed liquor which is depleted in organic compounds, but enriched in sodium carbonate and/or sodium oxalate. The wet-oxidised processed liquor is directed to a leach tank (18) immediately following a dry oxidation process. The dry oxidation process is typically a liquor burner (16). A substantial component of the sodium compounds in a feed slurry to the liquor burner (16) is reacted to produce a processed discharge product. The liquor burner discharge product is directed into the leach tank (18), where it dissolves in the processed liquor from the wet oxidation process (12). The resultant increase in the leach tank solutions ionic strength causes the sodium carbonate and sodium oxalate to become supersaturated, so that they precipitate from the leach tank liquor. The precipitated sodium carbonate and/or sodium oxalate are separated (20) from the leach tank liquor and recycled in a mix tank (14) provided the feed slurry to the liquor burner (16). When the wet and dry oxidation processes are combined in this way, the combined system is capable of destroying and fully causticising twice the amount of TOC as the liquor burner alone.

Title: Helium droplet mass spectrometery (hdms)
Inventor: BEMISH RAYMOND JOHN
IPC: G01N27/62
Filed: 2001-10-09
Granted: 2004-12-07
Abstract: A method and device for mass spectrometry analysis, wherein a mass spectrometer is adapted for use with helium droplets, as an ionization site medium, with a proton being initially captured by a large helium droplet (-10,000 helium atoms) and then cooled evaporatively to 0.4 Kelvin. The protonated helium droplet then picks up a neutral molecule of interest and the neutral molecule is protonated inside of the droplet with the liquid helium droplet acting as a heat bath to provide rapid cooling of the newly formed protonated molecule. As a result, there is essentially no energy available, at 0.4 Kelvin, for the protonated molecule to fragment. Remaining liquid helium is removed and the stably maintained protonated molecule is detected by a mass spectrometer. Since the molecules do not fragment when protonated (ionized), each compound in a mixture analyses gives one mass and the number of ions of a particular mass detected is directly proportional to the molar percentage of that mass in the sample. The device for effecting the method, comprises the elements of : (1) Helium cluster or droplet source; (2) Proton source for introduction of protons to the droplet (i.e., ionization); (3) atmospheric pressure (AP) Source for reduction of pressure to form a low pressure stream; (4) Cell pick-up elements where compound molecules are protonated or ionized at low temperature; (5) Desolvation area for removal of residual helium; and (6) Mass spectrometer and detector.
