Title: Mixture regulation in an internal combustion engine
Inventor: BENNINGER NIKOLAUS
IPC: F02D41/14
Filed: 1991-01-11
Abstract: A method of regulating the fuel-to-air ratio in a mixture of fuel and air fed to an internal combustion engine (10) gives consideration to the gas storage capacity of an exhaust gas catalytic converter (16) associated with the engine, the degree of conversion by the converter being dependent on the oxygen component in the exhaust gas. Since this is influenced by stored oxygen delivered up by the converter, the degree of conversion of the catalyser can be optimised by targeted enrichment or weakening of the ratio of fuel to air. For this purpose, the difference ( DELTA  lambda ) between a measured value for the air number  lambda  and a target value  lambda s is determined and the value of  lambda  is varied above and below said target  lambda s so that the value of the integral function of this difference converges towards a preset value (IS). <IMAGE>

Title: A catalytic combustion chamber
Inventor: FLETCHER MARY BRIDGETT
IPC: F23R3/40
Filed: 1992-07-14
Abstract: A gas turbine catalytic combustion chamber (22A) comprises a first catalyst coated ceramic honeycomb monolith (30) which forms a first catalytic combustion zone. A hydrocarbon fuel supplied from fuel injectors (28) is burnt in air supplied from inlet (24) in the first catalytic combustion zone. A plurality of injectors (66) inject hydrogen onto a plurality of regions of the first catalyst coated ceramic honeycomb monolith (30). The hydrogen has greater activity than the hydrocarbon at ambient temperatures, and the hydrogen burns in the catalytic combustion zone and increases the surface temperature of the catalyst to a temperature in the region of 350 DEG C to 400 DEG C. The catalytic combustion of the hydrocarbon fuel in the first catalytic combustion zone occurs at this temperature, and once it has been reached the process can continue on its own and the hydrogen supply is switched off. <IMAGE>

Filed: 1994-06-20
Abstract: A method of, and apparatus for editing recorded material stored in the form of electrical signals in or on a storage medium, to give a desired duration to a reproduction of the recorded material, by establishing a threshold corresponding to an information content below which the recorded material is dispensible and altering the duration of one or more of the periods during which the recorded material falls below that threshold, to obtain the desired duration for the reproduction. More specifically a method and apparatus for duration editing of sound recordings is described, in which the threshold represents a given signal amplitude, which may be selected with reference to stored data indicative of the amplitude of the originally recorded signal with time, and derived from it. The recording apparatus includes circuitry for recording the audio signals and profile data derived from it on a disc. The profile value read out from the disc are compared with a user adjustable threshold to modify the duration of the recorded material. <IMAGE>
