Title: Process for the preparation of a magnesium salt of a substituted sulphinyl heterocycle
Inventor: HOEGBERG JAN-AKE
IPC: C07D401/12
Filed: 1997-04-22
Granted: 2001-04-10
Abstract: A novel process for the preparation of a magnesium salt of a substituted sulfinyl heterocyclic compound containing an imidazole moiety according to formula I. The process is carried out by mixing the substituted heterocycle of formula (I) with a weak base and a magnesium source. The base and the magnesium source are selected to result in residues, which are easy to remove during the reaction. The invention also relates to the use of the produced compounds in medicine. Compounds according to formula I are: (see formula I) wherein Ar is (see formula II or III) Z is (see formula IV or V) and X is (see formula VI or VII) wherein, N inside the benzene ring of the benzimidazole moiety means that one of the carbon atoms substituted by R7-R10 optionally may be exchanged for a nitrogen atom without any substituents; R1, R2 and R3 are the same or different and are selected from the croup consisting of hydrogen, alkyl, alkylthio, alkoxy, fluorine-substituted alkoxy, alkoxyalkoxy, dialkylamino, piperidino, morpholino, halogen, phenylalkyl and phenylalkoxy, wherein alkyl and alkoxy groups may be branched or linear or contain a cyclic alkyl group; R4 and R5 are the same or different rind are selected from the group consisting of hydrogen, alkyl and aralkyl; R6 is selected from the group consisting of hydrogen, halogen, trifluoromethyl, alkyl and alkoxy; R7-R10 are the same or different and are selected from the group consisting of hydrogen, alkyl, alkoxy, halogen, haloalkoxy, alkylcarbonyl, alkoxycarbonyl, oxazolyl and trifluoroalkyl; R11 is hydrogen; and R12 and R13 are the same of different and are selected from the group consisting of hydrogen, halogen, alkyl and alkoxy groups, wherein alkoxy groups may be branched or straight C1-C9-chains or contain a cyclic alkyl group.

Title: Control channel for nonterrestrial cellular mobile telecommunication station
Inventor: RAY JIMMY CARROL
IPC: H04B7/185
Filed: 1997-09-12
Granted: 2003-11-18
Abstract: The multidimensional cellular mobile telecommunication system extends the usage of existing cellular mobile telecommunication radio frequencies allocated for ground-based communications to non-terrestrial mobile subscriber stations by adding an overlay of non-terrestrial cells of predetermined geometry and locus in space to the existing ground-based cellular cell site network. The polarization of the signals produced by the non-terrestrial antenna elements is a polarization that is different than and preferably substantially orthogonal to the polarization of the cellular radio signals produced by the ground-based antennas, such as a horizontal polarization, to thereby minimize the possibility of interference with the vertically polarized ground-based radio signals. Furthermore, the control signals exchanged between the non-terrestrial mobile subscriber stations and the non-terrestrial cell site controller are architected to avoid the possibility of interference with ground-based cell site transmitter-receiver pairs. In particular, the control channels used for the non-terrestrial mobile subscriber stations are selected such that the control signals transmitted in these channels are unrecognizable to the ground-based mobile subscriber stations and cell site transmitter-receiver pairs, so that even if broadcasts from a non-terrestrial mobile subscriber station reach a ground-based mobile subscriber station or cell site receiver, they cannot be interpreted and are rejected out of hand.

Title: Coating bituminous substrates
Inventor: KELLY DAVID GOODRO

Granted: 2008-12-23
Abstract: The quality of a mastic coating system for bituminous substrates is improved through the use of a topcoat composition and/or tiecoat composition comprising a water-insoluble latex polymer. The latex polymer has a Tg of from -25°C to 20°C and is prepared from a monomer mixture comprising: (a) at least 20 % by weight of at least one hydrophobic monomer selected from the group consisting of (C8 to C24) alkyl (meth)acrylates; (b) 0 or up to 45% by weight of at least one vinyl aromatic monomer; wherein the weight of (a) and (b) together constitute at least 25% by weight of said monomer mix (c) 0 or up to 75% by weight of at least one monomer selected from the group consisting (C1 to C4) alkyl (meth) acrylates; and (d) 0 or up to 5% by weight of at least one monomer selected from acrylic or methacrylic acid; wherein when (b) is not present in the monomer mix the amount of (d) is in the range from 0 or up to less than 3% by weight. The mastic coating system has increased adhesion and blistering resistance when the coating is exposed to ponded water and may have reduced bleedthrough of chemicals from the bituminous substrate.

Title: Method and apparatus for femoral resection
Inventor: LIPMAN JOSEPH
IPC: A61B17/56
Filed: 1998-01-27
Granted: 2003-12-02
Abstract: An instrument is provided for use in shaping a femur preparatory to implantation of a knee prosthesis. A gap checking device (40) is fixed to the distal end of the patient's femur and referenced to the epicondyles of the femur. The gap checking device (40) includes slots (70, 72, 74, 76, 78) through which a cutting instrument can be passed to shape the femur so that it can receive the femoral component of the prosthesis. One of the slots (70) enables the distal femoral cut to be made. The thickness of the gap setting device (40) is selected so that the distance between the distal femoral cut and the distal surface of the gap setting device plus the thickness of a shim resting on the cut proximal tibial surface is equal to the combined thickness of the tibial and femoral components of the prosthesis. This enables the flexion and extension gaps to be checked before the femoral cuts are made. The epicondyles can be located using intramedullary or extramedullary referencing. A special extramedullary locating device (10) is also described which is referenced to the trochlear groove of the femur and enables the placement of pins (38) in the epicondyles so that the gap checking device (40) can be properly situated with respect to the femur.
