Abstract: Method and apparatus for producing a water-in-fuel-emulsion and emulsifier-free water-in-fuel-emulsion. The apparatus for generating a fuel water emulsion for the operation of an injection pump, particularly that of a diesel motor, comprising a rotationally symmetric vortex chamber (1) with a tangential inlet and a tapering axial outlet. In order to generate a fine homogeneous emulsion in colloidal state, having a size of the suspended water droplets of 1000 nm or less, the axial end portion of the vortex chamber (1) facing away from the outlet is surrounded by a ring channel (7) running coaxially to the vortex chamber (1), the ring channel (7) being connected to the vortex chamber (1) via inlet slots (9) which are tangentially aligned to it and in which a fuel inlet channel (8) tangentially ends. An electromagnetically controlled water injection nozzle (10) leads into the end portion of the vortex chamber (1) at the inlet side thereof.

Abstract: A therapeutic lamp for biostimulation with polarized light, which comprises a light source with a power substantially between 30W and 300W, a reflector with a rotational paraboloid light reflecting surface arranged behind the light source so that the focal point substantially coincides with the point source, a polarizer arranged in the path to generate polarized output light which has a cross-section of at least 100 cm.sup.2. The lamp further comprises a first tube with a first axis coinciding with axis of rotation of the paraboloid surface, the reflector with the light source is fixed in the first tube so that a sealed connection is provided therebetween, a second tube with a second axis which closes an angle between 110.degree. and 120.degree. with the first axis, the tubes have substantially equal and circular cross-sections and are attached to each other to form an integral housing.

Abstract: Therapeutic lamp emitting polarized light, comprising a housing of three consecutive parts which define a common interior space, the first part being a handle having a substantially tubular form, the second part being a dome-shaped middle portion attached to an end of the handle, and the third part being a cylindrical frontal portion attached to the middle portion, the frontal portion having an axis which forms a first obtuse angle with the axis of the handle.
