20140353038 | WELL DRILLING TUBULARS BIN SYSTEM, AND METHOD FOR USE OF SYSTEM - A well drilling tubulars bin system comprises a well drilling tubulars bin and control device. The bin comprises a frame structure, and an elevator mechanism, for holding multiple layers of a plurality of well drilling tubulars. The elevator mechanism comprises a liftable support structure, and a left and right hydraulic cylinder. The support structure is liftable from a lower position to an upper position. The support structure is raised and lowered in a level manner, or with a tilt angle. The elevator mechanism comprises a first left lift arm and a first right lift arm. The first left and right lift arms are at a first end rotatably connected to the support structure, and at a second end opposite from the first end rotatably connected to the frame structure. The left and right hydraulic cylinders are connected to the respective lift arms for rotating the respective lift arm. | 12-04-2014 |

20080310788 | Rolling Bearing with Improved Rim Geometry - The invention relates to a rolling bearing comprising at least one bearing ring and a plurality of rollers, the bearing ring having a raceway for the rollers and at least one lateral rim for axially guiding the rollers. The roller has front face facing the rim and the rim has a rim bearing surface facing the roller. At least sections of at least the front face or the rim bearing surface have a toroidal camber in the direction of the rim bearing surface or the front face. | 12-18-2008 |
20090003747 | Rolling Bearing - The invention relates to a rolling bearing comprising at least one bearing ring and a plurality of rollers, the bearing ring having a raceway for the rollers and at least one lateral rim for axially guiding the rollers. The roller has a front face facing the rim and the rim has a rim bearing surface facing the roller. At least sections of at least the front face or the rim bearing surface are cambered in the direction of the rim bearing surface or the front face, said camber having a logarithmic profile of camber in at least one border section. | 01-01-2009 |

20150147362 | EASILY FORMULATED ZINC OXIDE POWDER - The present disclosure relates to polymeric siloxane coated zinc oxide powders having a mean particle size number distribution (D50) ranging from about 300 nm to about 600 nm and their use in sunscreen compositions. The relatively high surface area (in relation to particles of <100 nm) avoids agglomeration resulting in ease of formulation and high dispersal of the particles which tends toward less light scatter and hence better transparency in formulations. Furthermore, the combination of the particular particle size number distribution (D50) of zinc oxide ranging as above with bis(resorcinyl)triazine UV absorbers shows unexpected increased UV-A absorbance (320 to 400 nm) in comparison to the zinc oxide and bis resorcinyl triazine UV absorbers on their own at the same concentration. | 05-28-2015 |
