Abstract: Corrosion of metallic tubulars in an oil, gas or geothermal well may be inhibited by introducing into the well a dithiazine or dithiazine of the formula: (see formula I), (see formula II) or (see formula III) wherein R is selected from the group consisting of a C1 to C12 saturated or unsaturated hydrocarbyl group or a C1 to C10 .omega.-hydroxy saturated or unsaturated hydrocarbyl group;  R1 is selected from the group consisting of a C1-C24 straight chain or branched alkyl group or a C1-C24 arylalkyl; R2 is selected from the group consisting of X-R4-X, R4 being a C1-C6 alkyl group; and X is chlorine, bromine or iodine. The dithiazine may be isolated from a whole spent fluid formed by reaction of hydrogen sulfide and a triazine.  Alternately, the whole spent fluid containing the dithiazine may be introduced into the well. The dithiazines of formulae (II) and (III) are quaternized derivatives of the dithiazine of formula (I). In addition, the dithiazine or whole spent fluid or quaternized dithiazine may be formulated with at least one component selected from alkyl, alkylaryl arylalkyl or arylamine quaternary salts; mono or polycyclic aromatic amine salts;  imidazoline derivative or a quaternary salt thereof; a mono-, di- or trialkyl or alkylaryl phosphate ester; or a monomeric or oligomeric fatty acid.

Abstract: A walking assist device, which is to be worn on a person's leg, includes a shank link, a thigh member, and a knee mechanism. The thigh member is in contact with the person's thigh when the device is worn on the person's leg. The knee mechanism rotatably connects the shank link to the thigh member. When the shank link is in contact with the ground, the knee mechanism is configured to resist the rotation of the shank link relative to the thigh member to prevent the person's foot from contacting the ground and reduces ground reaction forces entering the person's foot.

Title: Determining the configuration of a base station of a mobile telephony network
Inventor: GALE SIMON JOHN
IPC: H04B7/06
Filed: 2009-11-12
Abstract: A base station for use in a mobile telephony network includes an antenna arrangement coupled to a transceiver arrangement for producing a plurality of beams. A method of testing the base station comprises detecting at the transceiver arrangement the signal strengths of a test signal received via the beams; comparing and/or correlating the said signal strengths detected at the transceiver arrangement; and using the results of the comparisons and/or correlations to determine the configuration of the antenna arrangement and transceiver arrangement and/or to detect faults. The comparison of average signal strengths can be used to detect cabling faults, and beam errors. The correlation of un-averaged signal strengths can be used to determine which beams have the same polarisation. Beam pointing directions and the allocation of antennas to sectors can be determined by monitoring handovers of mobiles moving between cells. Frequencies may be allocated to sectors according to a frequency re-use scheme.
