Abstract: The invention is related to diagnostic methods for detecting transmissible spongiform encephalopathies (TSEs) such as BSE and scrapie and related disease in humans. The invention provides use of guanidine thiocyanate (gdnSCN), or a functional equivalent thereof, for treating at least one sample derived from a mammal, including humans, for reducing the risk of scoring a false-positive test result in testing the sample for the presence or absence of aberrant prion protein.

Abstract: It is the object of the invention to make available a method of transferring user data packets from a terminal to a mainframe of an S-CDMA point-to-multipoint system, in which the data transfer is optimized. The method includes the steps of a repeated transmission of reference data packets coded with pilot codes for the duration of the connections between terminals and a mainframe, wherein the reference data packets contain previously known information, and the transmission of user data packets coded with communication codes include the user information to be transferred. In a preferred embodiment of the invention the user data packets are coded synchronously in time to the reference data packets, superimposed on these, and then modulated. Each terminal is allocated a pilot code, and at least one communication code.

Abstract: It is the object of the invention to make available a method of transferring user data packets from a terminal to a mainframe of an S-CDMA point-to-multipoint system, in which the data transfer is optimised. The method according to the invention is comprises the steps of a repeated transmission of reference data packets coded with pilot codes for the duration of the connections between terminals and mainframe, wherein the reference data packets contain previously known information, and the transmission of user data packets coded with communication codes comprising the user information to be transferred. In a preferred embodiment of the invention the user data packets are transmitted as coded synchronously in time to the reference data packets, superimposed on these and then modulated. Each terminal is allocated a pilot code, and at least one communication code.

Abstract: The object of the invention is to provide a cellular radio system, in particular a LMDS system wherein the utilization of the transmission capacity is optimized. The cellular radio system is characterized in particular in that each cell contains a base station, that at least one cell is divided into at least two sectors, that each sector comprises one non-overlapping zone and two overlapping zones, and that each base station is suitable to allocate at least one transmission unit (time slot or orthogonal code) simultaneously to at least two different terminals located in different, non-overlapping zones of a cell.

Abstract: Raw materials useable in the manufacture of paper, cardboard and carton are recovered from waste sludge. After precipitation of the coarse particles, the sludge is centrifuged to remove black particles and then divided by fractional screening into its fiber, filler, pigment and agglomerate components. The agglomerate component is shear-treated and again fractionated, while the fibers, fillers and pigments, following further treatment if necessary, are fed to their points of reuse.
