Title: A safety switching circuit comprising a plurality of microcomputers which process the same data items
IPC: G06F11/16
Filed: 1988-03-11
Abstract: Multi-channel safety switching devices require comparators for data to be output to the process so that a signal divergence can be recognised in time and possibly false information items can be kept away from the process. This requires a data-flow-independent checking of the comparators. A release signal (FG1) to be output by the comparator (VG1) when the microcomputer (MR1, MR2) to be monitored is operating correctly is output indirectly via an AND gate (UD1) to output signal converters (AR). A test circuit (TSG1) which has a bistable characteristic is connected to the AND gate (UD1). The test circuit evaluates a key information item (SN1) output by the microcomputer (MR1), which counts as acknowledgement of a predetermined computer routine of the microcomputer (MR1). In dependence on this, an enable code is output for the AND gate (UD1). The abovementioned safety switching devices can be used, in particular, in the case of process controls with safety responsibility, for example in the case of railway signalling. <IMAGE>

Abstract: A method and apparatus for production of iron from iron compounds is provided. There is a first stage of pre-reducing the iron compounds in a first chamber (1) having a rotationally symmetrical wall (3), and a second stage of further reducing the iron compounds in a second chamber (4) below the first chamber, fuel and oxygen being supplied to the second chamber. A reducing gas passes upwardly into the first chamber to effect the pre-reduction therein. Oxygen is fed to the first chamber. The iron compounds in the first chamber at least partly melt and then flow downwardly along the wall towards said second chamber. The iron compounds are introduced into the first chamber in particle form and by means of a carrier gas which provides one or more jets. The oxygen is fed into the first chamber at least partly in the form of one or more jets having tangential components. The velocity of introduction of the oxygen is greater than the velocity of introduction of the iron compounds in the jets thereof, while the velocity of introduction of the iron compounds is such that the particles reach the wall of the first chamber in an at least partly molten state. <MATH>

Title: Addressing of groups of broadcast satellite receivers within a portion of the satellite footprint
Inventor: EARNSHAW NIGEL CHRISTOPHER
IPC: H04H40/90
Filed: 2006-08-01
Granted: 2010-08-11
Abstract: A method and system enables the selective addressing of groups of broadcast receivers within part of a satellite footprint. It uses two satellites 10,12 having a common transmission band to transmit respective signals, and at receivers 50,50' in the footprint the phases of the signals received from the two satellites are compared. This phase difference is dependent upon receiver location, but by measuring phase difference no absolute timing or phase measurement is required. A common key is generated at the receivers in a certain area. The output of selected receivers 50' is fed back to the broadcast control centre 30 and is used to encode the location-based services for that area.  Preferably the operation is conducted on multiple frequencies and in multiple rounds of such frequencies. A multibit keyword can be directly generated at the receivers by use of a discrete Fourier transform (DFT) and combining its outputs for different rounds.
