20120148647 | Photoresponsive Sunscreen Composition - The present invention relates to a composition containing a sunscreen agent capable of undergoing protonation or deprotonation to form a protonated or deprotonated, respectively, sunscreen agent which absorbs, scatters or reflects more or less UV radiation than it does before being protonated or deprotonated, respectively, and a photoresponsive acid or base generating system which is capable of protonating or deprotonating, respectively, said sunscreen agent when the composition is exposed to UV radiation. Further subject matter of the present invention is a microcapsule comprising a sunscreen agent capable of undergoing protonation or deprotonation to form a protonated or deprotonated, respectively, sunscreen agent which absorbs, scatters or reflects more or less UV radiation than said sunscreen agent does before being protonated or deprotonated, respectively, wherein said sunscreen agent is present in said microcapsule substantially in its protonated or deprotonated form that absorbs, scatters or reflects less UV radiation than said sunscreen agent does upon protonation or deprotonation, respectively. The composition and microcapsule according to the invention are particularly useful for providing sunscreen formulations for cosmetic applications and for providing dermatological formulations for medical applications. | 06-14-2012 |
20120309052 | INDUCIBLE BACULOVIRUS SYSTEM IN INSECT CELLS - The present invention describes a novel baculovirus protein expression system in insect cells, where the expression of recombinant protein(s) is inducible. By the inducible expression systems of the invention, expression of the recombinant protein of interest can be repressed during virus amplification, and thereafter activated in the presence or absence, respectively, of an inducing molecule or by a change in environmental conditions. The novel expression system does not produce significant levels of recombinant protein by baculovirus-infected cells during virus amplification prior to induction, thereby reducing selection pressure on the expression cassette for the recombinant protein. When induction is initiated, an increased yield of recombinant protein is thus produced relative to presently available, non-inducible baculovirus expression methods. Further, it is demonstrated herein that the yield of protein expression derived from the described methodology further increases relative to non-inducible systems as the scale of protein expression increases. | 12-06-2012 |

20160045900 | Composite Material Containing A Bismuth-Molybdenum-Nickel Mixed Oxide Or A Bismuth-Molybdenum-Cobalt Mixed Oxide And SIO2 - The present invention relates to a process for producing a composite material and also the composite material itself. The composite material contains a bismuth-molybdenum-nickel mixed oxide or a bismuth-molybdenum-cobalt mixed oxide and a specific SiO2 as pore former. The present invention also relates to the use of the composite material according to the invention for producing a washcoat suspension and also a process for producing a coated catalyst using the composite material according to the invention. Furthermore, the present invention also relates to a coated catalyst which has a catalytically active shell comprising the composite material according to the invention on a support body. The coated catalyst according to the invention is used for preparing [alpha],[beta]-unsaturated aldehydes from olefins. | 02-18-2016 |

20110114392 | DRILLING APPARATUS WITH REDUCED EXPOSURE OF CUTTERS AND METHODS OF DRILLING - A rotary drilling apparatus and method for drilling subterranean formations, including a body being provided with at least one cutter thereon exhibiting reduced, or limited, exposure to the formation, so as to control the depth-of-cut of the at least one cutter, so as to control the volume of formation material cut per rotation of the drilling apparatus, as well as to control the amount of torque experienced by the drilling apparatus and an optionally associated bottomhole assembly regardless of the effective weight-on-bit are all disclosed. The exterior of the drilling apparatus may include a plurality of blade structures carrying at least one such cutter thereon and including a sufficient amount of bearing surface area to contact the formation so as to generally distribute an additional weight applied to the drilling apparatus against the bottom of the borehole without exceeding the compressive strength of the formation rock. | 05-19-2011 |
