A tire-balancing including a tire-balancing material in a first pocket of the system and at least one tire accessory such as a tire-valve core in the second pocket of the system. The first and second pockets are spatially separated from one another with a seal and a line of perforation. The first pocket has a duct dimensioned to release the particles, oriented towards the second container, and sealed from the second container. The methods for fabrication of the tire-balancing system and balancing a tire with the use of such system. Before use, the first pocket is opened by separating the second pocket along the perforation, and placed in a tire let a flow of the particles from inside the first container into the tire through the duct. The tire-valve core is removed from the second container and applied to the wheel.

Tire-balancing system and use thereof

The invention relates to a device and a method for the production of three-dimensional objects, in particular of at least parts of dental prosthetic restorations, by a stripping device wiping off plastic material, which protrudes vertically beyond a container, into a collecting container and forms a projection surface. According to the invention, a stripping device and a light source are coupled and simultaneously guided, at a defined distance, across the liquid light-curing plastic material, whereby the stripping device is guided at a defined distance right ahead of the light source and forms the projection surface for the illuminated field of the light source.

More efficient method for producing three-dimensional objects by means of a rapid prototyping process

The invention relates to a method for producing a homogenized distribution of light quantity with a spatial light modulator that comprises a multitude of controllable and tiltable micro-mirrors that are arranged in rows and columns, in which the light of a spatially emitting light source is projected by means of an optical system and an illuminated field of the projected light source is guided over a projection surface, whereby, towards the middle of the illuminated field, an increasing number of pixels is not being illuminated such that the time integral attains a homogenization of the light intensity of all pixels that are illuminated on the projection surface. The invention also relates to a rapid prototyping method, in which a liquid light-curing plastic material is illuminated by means of a method of this type, preferably is illuminated by UV light, whereby the illuminated field is projected onto the surface of the plastic material and the plastic material is cured through the illumination of the illuminated field.
