Abstract: In a prestressed concrete railway sleeper whose sleeper body (1) consists of two supporting bodies (2, 2') carrying the rail fastenings and a centre part (3) of smaller cross-section, the prestressing elements (4), such as, for example, steel bars, wires or strands, starting from a point where they are united in a vertical and/or horizontal plane in the sleeper centre, are run radially and rectilinearly to the sleeper ends (5, 5'), where they are anchored in uniform distribution over the cross-sectional areas of the sleeper ends. By the uniting of the prestressing elements (4) in the sleeper centre, the use of a sleeper body having a narrow, high centre web and wide sleeper ends also becomes possible for prestressed concrete sleepers, in which sleeper body only slight alternating bending moments arise in the centre part or a unidirectionally positive pattern of the bending moments can be permitted over the entire length of the sleeper. <IMAGE>

Abstract: A central station (SC) is connected in series with the stations by a looped connection comprising a message loop (BM), a clock-signal loop (BH) and a state-control loop (BCE). Each station comprises an interface (I) connected to the various loops of the connection. The message loop routes messages transmitted by the central station destined for at least one interface, the responses from the interfaces, and messages transmitted by the interfaces destined for the central station. The clock-signal loop routes a clock signal transmitted by the central station and the state-control loop routes a state-control signal transmitted by the central station, this signal having a first value for a drive mode of operation and a second value for a reserve mode of operation of the interfaces; the passing from the first to the second value enables the control of a reset to zero of the interfaces. The clock and state-control signals have the same circulation sense, the messages having an inverse circulation sense.

Patent ES-2056328-T3 (ES)
Inventor: RONCHI CLAUDIO
IPC: G01J5/00
Filed: 1990-09-24
Granted: 1994-10-01
Abstract: The invention concerns a multi-wavelength pyrometer for the measurement of the temperature and emissivity of a surface above 900 K. The pyrometer has several radiation detectors sensitive in different wavebands  lambda 1...  lambda i...  lambda n as well as a data processor to which the detector outputs are fed after digitalization and which calculates the temperature of the surface from these detector outputs using Wien-Planck's law, assuming the surface is a perfect black body. The emissivity is then calculated, as a function of the temperature and the wavelength, from these calculated temperature values using an approximation method, and from this, the required temperature. The invention calls for the differences between the actual pyrometer signals and the signals which would be expected from the assumed emissivity and the temperature calculated from this emissivity to be determined for various approximations and various wavelengths. The approximation which gives, for all the wavelengths, the least sum of the squares of these differences is then selected.

Abstract: A process for the efficient production of Cl2 from gaseous HCl, using a catalyst (1) containing a transition metal oxide, an alkali metal chloride, and, optionally, a trivalent rare earth chloride, operates efficiently at moderate temperatures and without volatilization of the catalyst (10). The process comprises two steps: 1) a chloridizing step in which the HCl is contacted with the catalyst (1) at an elevated temperature, converting the transition metal oxide to a transition metal chloride with elimination of water; and 2) an oxidizing step in which the transition metal chloride produced in the first step is contacted with a source of oxygen at a temperature at least about 300  DEG C but less than 400  DEG C and sufficiently high that Cl2 is envolved and the transition metal chloride is reconverted to a transitional metal oxide. The temperature of the oxidizing step is increased over that of the chloridizing step. Preferably, the transition metal oxide is MnO2, in which case the MnO2 is converted to MnCl2 in the first step with the release of Cl2. The transition metal oxide can also be Co2O3, Co3O4, Cr2O3, NiO, Ni2O3, Mo2O3, or CuO.
