A stable topical alcohol-free aerosol foam containing one or more keratolytic agents is provided. The foam-forming formulation is an oil-in-water emulsion which contains one or more hydrofluoroalkane (HFA) propellants and one or more keratolytic agents. The keratolytic agent may be present in either phase of the emulsion or dispersed in the emulsion. The oil phase may consist at least in part of the HFA propellant. The foam is stable on the skin for at least 5 minutes at body temperature and disappears into the skin upon rubbing or after prolonged standing. The formulations may not contain additional co-solvents or non-HFA co-propellants. The formulations demonstrate reduced intensity of the odor and / or color associated with the keratolytic agent(s) as compared to conventional formulations containing keratolytic agents.

A motor vehicle headlight comprises a reflector arranged to be oriented along the horizontal axis of the vehicle, together with a light source situated in the vicinity of the focus of the reflector. It also includes a filter which is able to occupy a withdrawn first position in which it does not interfere with the light beam, and a working second position in which it interferes with at least part of the beam. Means are provided for moving the filter between its working and withdrawn positions. The filter is a diffusing and absorbing filter which does not substantially modify the wavelengths of the emergent light as compared with the incident light, and which is arranged so that, with the filter in the working position, a second type of light beam is produced having a reduced intensity, and, optionally, a modified photometric distribution.

An apparatus is provided for automatically reducing glare produced from a spatial scene by reducing the intensity of light rays propagating from points in the three-dimensional spatial scene towards an optical element having a field of view. Further, an apparatus is provided that automatically reduces interfering illumination produced from an illumination source by reducing the intensity of light rays propagating from the illumination source towards a sensor having a field of view of radio communication. Both apparatus include an electro-optical element having an optically transparent surface including a plurality of pixels through which the field of view of the optical element or the sensor passes. Each pixel has a controllable light transmittance for selectively reducing the intensity of incident light rays propagating from one or more points from the illumination source, through the pixel, then towards the sensor or optical element. An image acquisition device is included for acquiring one or more images of the illumination source within the field of view of the sensor or optical element. A processor is also included for processing the acquired images and determining at which pixels the light transmittance is to be actively controlled in order to reduce the intensity of incident light rays before reaching the sensor or optical element. A control is also provided for actively controlling the light transmittance of the determined pixels so that after incident light rays propagate through the determined pixels, the incident light rays propagate towards the sensor or optical element with reduced intensity.

A backrest device for a chair, capable of, without a reduction in its strength and rigidity, effectively bending backward so as to follow the shape of the back of a person seated on the chair, providing the person with excellent sitting comfort. In the backrest device, a back board (11) is supported by a backrest frame, and the back board (11) has a flexible back stopper (13) on the inner side of a back frame (12). The thickness of a vertical intermediate section of the back stopper (13) is gradually increased from both left and right sections of the intermediate section toward the center such that the thickness is less in both left and right sections and is maximum at the center.

According to the invention, an incident X-ray is transmitted in a wide angular sector towards a sample of amorphous material that scatters back the X-rays. The method comprises: a step of storing experimental photonic intensity measures based on the incidence angle; a step of correcting the experimental intensity while taking into account at least the absorption phenomena within the sample based on the penetration length l of the incident wave inside the sample before reflection; a standardisation step of reporting the corrected intensity resulting from the experimental intensity to an electronic intensity according to a standardisation coefficient (Alpha); a step of calculating a discretised function Q.i ( Q ), i being a reduced intensity resulting from the measures of the corrected and standardised experimental intensity and Q being the module of the wave scattering vector proportional to the value sin Theta / Lambda, 2Theta being the scattering angle and Lambda being the length of the transmitted wave, the standardisation constant (Alpha) recursively varying in order to minimise the slope of the affine straight line (42) obtained by linear regression of the values of the function Q.i ( Q ), the reduced intensity values being calculated upon each iteration for a penetration length l, and the sought (41) function Qi ( Q ) corresponding to the minimum slope; and a step of determining the structure factor from the distribution of the radial atomic concentration Rho(r) based on Qi ( Q ).

Spatial acquisition of measurement data over a cross section of a high-energy, high-intensity radiation beam bundle without impairment of measuring accuracy due to saturation or degradation of detectors occurs by imaging an entire cross section of the beam bundle on a shading element, the cross section being separated successively into partial beam bundles having reduced cross sections and reduced intensity through movement of at least one opening, whereby measurement values of the partial beam bundles passing the opening are associated temporally and spatially with positions of the opening.
