Abstract: A method for mixing a pulverulent material in a main gas flow with a view to achieving uniform distribution of the pulverulent material. The turbulence in the main gas flow is increased in a vortex-generating zone. The pulverulent material is introduced into the main gas flow, in a mixing zone, with a carrier gas flow whose net motion during introduction is essentially opposite to the main gas flow. The mixing zone is positioned downstream of the vortex-generating zone and in the vicinity thereof. The carrier gas flow with the pulverulent material is in a rotational zone given a helical motion, whose axis of symmetry is essentially parallel with the direction of flow of the main gas flow, and is introduced into the mixing zone in the form of a divergent hollow cone. A device for carrying out the method comprises a gas duct (1) for the main gas flow with vortex-generating means (4) and an introducing means (11) for introduction of pulverulent material in dispersed state into a carrier gas flow.

Abstract: An apparatus and method for reducing sparseness in a coded speech signal. Sparse codebook values are generated from a codebook. An anti-sparseness operation is performed on the sparse codebook values to produce output codebook values having a greater density of non-zero values than the sparse codebook values. The output codebook values are processed by a speech processor to generate an encoded speech signal during an encoding operation or a decoded speech signal during a decoding operation.

Abstract: A photoconductive switch comprises a first layer (1), two contact layers (2, 3) arranged on said first layer and connectable to different potentials for applying a voltage thereacross, said first layer being adapted to be conducting upon applying a voltage across said contact layers when exposed to light from an illumination source of an energy high enough for lifting charge carriers from the valence band to the conduction band of the material of said first layer. The illumination source is an excimer lamp, in which unstable electronically excited dimers are formed when a voltage is applied across first and second electrodes (12, 13) separated by a gas or gas mixture. The dimers so formed decompose into two gas atoms while emitting a photon of an energy suitable for lifting charge carriers from the valence band to the conduction band of the material of the first layer.

The contact electrode arranged on the first side of the first layer is laterally displaced with respect to the contact electrode arranged on the opposite second side of the layer with a lateral distance separating them.
