Abstract: The invention relates to a tape suitable for use in fuel cells, to an electrode suitable for use in a fuel cell, to a method for sintering an electrode of this type and to a fuel cell which contains an electrode of this type. The invention provides a tape with improved properties, which is characterised in that said tape contains LiCoO2. A tape of this type can be produced in a manner known per se using LiCoO2 and a binder. Expediently, a plasticiser and/or dispersant and/or anti-foam is used together with the binder, as is known per se for the preparation of tapes. Platelets can be produced from such a tape, which platelets can then be sintered, optionally after stack-ing. Sintering is expediently carried out in an atmosphere consisting of 60 to 80% air and 40 to 20% carbon dioxide, in particular 68 to 72% air and 28 to 32% carbon dioxide. A suitable temperature programme is chosen for sintering. Good results are obtained by heating to 250 DEG C at a heating rate of 100 DEG C per hour, then heating to 450 DEG C at a heating rate of 50 DEG C per hour, then heating at a heating rate of 100 DEG C per hour to the desired sintering temperature of 800 to 1000 DEG C and finally, after sintering, cooling to room temperature at a rate of 100 DEG C per hour. Of course, the invention also relates to fuel cells which are provided with a material according to the invention. <IMAGE>

Abstract: A method of C-terminal peptide sequencing. The peptide is reacted with an activated support derivatized with a mixed anhydride of isothiocyanic acid and carboxylic or carbonic acid, under basic conditions. The peptidyl thiohydantoin which forms is separated from the solid support and further reacted with a cleaving agent carried on a second solid support, to release a free C-terminal amino acyl thiohydantoin from the peptide. The free thiohydantoin is analyzed to determine the C-terminal peptide residue. The residual peptide can be recycled through the supports for successive C-terminal residue determinations.

Abstract: Apparatus for automated polyelectrolyte measurement of liquid process materials including a sample vessel which defines an electrically insulating, cylindrical cavity below a larger-diameter reservoir. Electrodes are located at the ends of the cylindrical cavity and an insulating piston is reciprocated with a predetermined, small clearance within the cavity. The charge displacement is measured between the electrodes. An outlet channel opening at the floor of the cylindrical cavity is connected to an outlet pipe. A rinsing duct with valve control for introducing a rinsing fluid into the reservoir. A controller is connected to an actuator for reciprocating the piston, to a valve in the outlet pipe and to the rinsing valve. After each polyelectrolyte measurement the substance under test is removed from the sample vessel through the outlet channel, rinsing fluid is introduced, and the rinsing fluid is removed through the outlet channel while the piston reciprocates. The reciprocation of the piston provides a pumping action which is used to expel the substance under test and enables effective rinsing and cleaning of the apparatus with no need for manual intervention.

Abstract: A process for removing H2S from biogas is provided, wherein the biogas is treated with an alkaline scrubbing liquid, the alkalinity necessary for absorption of H2S originating from an aerobic biological waste water treatment plant. Thus, the water/biomass mixture form the aerobic treatment or the clarified effluent can be used as a scrubbing liquid. The water flow/gas flow ratio in the scrubbing process is preferably 0.2 or greater. The liquid wherein H2S is absorbed can be recycled to the aerobic phase for oxidising the H2S. The process can be performed using a closed column gas scrubber equipped with inlet and outlet for biogas, inlet and outlet for treated waste water and means for contacting biogas and waste water.

Abstract: In order to produce a coil former (5C) particularly suitable for small and safety transformers, the invention calls for several shells (5c1, 5c2, 5c3) made of electrically insulating material to be disposed one over the other in layers. Each shell is U-shaped in cross-section. In addition, each shell is dimensionally stable in the absence of a force acting on it, but changes shape elastically under the action of a force. The shells form a ring with at least one gap (18). At this gap, the ends (15) overlap.

Abstract: The invention relates to an electrical logging method and apparatus using electrodes. The apparatus comprises an annular current electrode (Ao) mounted on a body and guard electrodes (A2, A'2) disposed on the body above and below the annular current electrode. A first measurement current (Io) is emitted by the central current electrode (Ao) and focusing currents are emitted by the guard electrodes (A2, A'2). A first output signal representative of the deep resistivity of the formations is generated in response to the first measurement current (Io). One of the guard electrodes (A2) comprises two longitudinally spaced-apart portions, and an array of azimuthal current electrodes (Aazi) that are circumferentially spaced-apart from one another is disposed between these two portions. Second measurement currents (Aazi) emitted by the azimuthal current electrodes (Aazi) are focused longitudinally by the currents emitted by the said two portions of the guard electrode (A2). Second output signals are generated in response to the second measurement current (Iazi), which output signals are representative of the resistivity of the formations in a plurality of directions around the borehole. A high resolution resistivity signal is calculated as a function of the mean of the second measurement currents (Iazi). <IMAGE>

Abstract: The invention provides an improved system for masking the free edge of a window gasket in preparation for re-painting or re-finishing a vehicle. The system includes a method of painting a vehicle which comprises introducing a flexible plastics strip beneath a window sealing gasket in the vicinity of a part of the vehicle to be painted, the plastics strips having a tapered profile in cross-section so that as the strip is pressed beneath the gasket, the latter is lifted and held in the raised position, masking the edge of the raised gasket and applying paint to the vehicle so that paint reaches the area normally covered by the edge of the gasket. Generally, the strip is a plasticised polymer in the form of a triangular cross-section having one side longer than the other two. An applicator is also described which comprises a handle and a pointed end for lifting the free edge of a window sealing gasket, the applicator having a recess or aperture adjacent to the pointed end, said recess or aperture being shaped to correspond approximately with the cross-section of the flexible, plastics strip. <IMAGE>
