Abstract: A composition comprised of asphalt and filler, wherein said filler is comprised of particles that comprise an inorganic core and a coating disposed on said core, and wherein at least about 60 weight percent of said particles are smaller than about 212 microns.

Abstract: A mineral composition that contains at least about 90 weight percent of headlap granules, at least about 50 weight percent of calcium carbonate, and from about 0.1 to about 1.0 weight percent of a pigmented material. The pigmented material contains from about 10 to about 35 weight percent of pigment and from about 90 to about 65 weight percent of a resin. The mineral composition has superior adhesion properties; when it is tested in accordance with ASTM Standard Test D 4977-03, it loses less than 5 grams of material.

Abstract: A mineral composition that contains at least about 90 weight percent of headlap granules, at least about 50 weight percent of calcium carbonate, less than about 100 parts per million of a metal selected from the group consisting of arsenic, barium, cadmium, chromium, lead, mercury, selenium, and silver, and less than about 100 parts per million of a polycyclic aromatic hydrocarbon. This composition, when tested in accordance with ASTM Standard Test D 4977-03, loses less than 5 grams of material.

Abstract: A guide system for signal lines includes a guide tube, through which the signal lines are guided, a cooling system which laterally surrounds the guide tube and has at least one coolant chamber and at least one inlet and at least one outlet for the coolant. The coolant chamber is tubular in construction and is hermetically sealed by a seal at least at one end face.

Abstract: A phototherapy system and method for automatically replacing a failed light source with a new light source once a failure of a first light source is detected. This system permits the new light source to assume a coaxially aligned position with the proximal end portion of a light transmission medium in place of the failed light source without any manual input by the user. In addition, an improved coupling system is provided for coupling the light transmission medium to the illumination device housing the light sources. The coupling system prevents pull out of the light transmission medium from the illumination device over nearly all rotational angles of the proximal end of the light transmission medium relative to the housing, and over only a relatively small range of angles will some degree of pull out force enable the light transmission medium to be decoupled from the illumination device.
