| 20090167468 | ELECTRICAL CIRCUIT BREAKER HAVING A PROTECTIVE FUNCTION - An actuating unit or actuating mechanism and release for a circuit breaker. The magnetic mechanism of the release includes a magnet armature, which can move linearly in a magnet coil, is in the form of a tripping plunger and can be moved towards a permanent magnet counter to the force of a storage compression spring and is held fixedly by said permanent magnet in the case of a magnet coil through which no current is flowing. The tripping unit is in the form of a mechanical force store. After a tripping action, the mechanical force store needs to be reset manually again. For this purpose, a rotary movement of the drive shaft with an angular displacement of from 20 to 30 degrees takes place in the opposite direction to the ON switching rotary movement. | 07-02-2009 |

| 20090065338 | CIRCUIT BREAKER FOR MOTOR PROTECTION AND/OR LINE PROTECTION - A manually operated circuit breaker for motor protection and/or line protection includes a basic board including a switching mechanism, a contact device, and a main current path. The switching mechanism includes a switching apparatus and a breaker latching mechanism. The circuit breaker includes a manual actuating device disposed in a housing part protruding from an operating front and configured to activate the switching mechanism via a rotary knob and an actuating shaft disposed perpendicular to the operating front. The circuit breaker includes an electronic control unit module pluggable onto the basic board and configured to be set with at least one control variable for a fault scenario so as to activate the switching mechanism by indicating a settable fault scenario. The electronic control unit is supplied with a voltage from the main current path via the contact device. An actuator unit including an energy storing device is configured to activate the breaker latching mechanism, and a tripping element is configured to respond to a settable fault criterion. | 03-12-2009 |

| 20090280179 | Resorbable Calcium Phosphate Based Biopolymer-Cross-Linked Bone Replacement Material - A resorbable bone replacement material made of calcium phosphate particles of different phases which are embedded in an inventive-specific cross-linked collagen matrix. The goal is to form a non-brittle, bone replacement moulded body having a positive fit, i.e. having a shape which is anatomic and/or corresponds to the defect, which perfectly fills the bone defect and can be resorbed thereby. Said goal is achieved by producing the bone replacement material made of a mixture of calcium phosphate particles which is embedded in an inventive cross-linked collagen matrix. In particular, the collagen cross-linking is achieved by a Laccase-induced peptide cross-linking and suitable bridge molecules. Essentially substituted dihydroxyarmotes and/or substrates of the lignolytic polyphenoloxidases, such as Laccases, are suitable as bridge molecules. Also, monocyclic ortho-dihydroxyaromates, monocyclic para-dihydroxyaromates, bicyclic monohydroxyaromates, polycyclic monohydroxyaromates, bicyclic dihydroxyaromates, polycyclic dihydroxyaromates, bicyclic trihydroxyaromates, polycyclic trihydroxyaromates, or mixtures thereof are used. The inventive hydroxyaromates are not part of a polymer chain as opposed to the known conchal adhesive. | 11-12-2009 |
| 20110040086 | Novel Beta-Lactam Antibiotics, Methods for Their Production, and Their Use - The invention relates to novel antimicrobial agents that are based on β-lactam derivatives and are produced by reacting previously known β-lactam derivatives with polyphenol oxidase substrates under the influence of free radicals and by forming salts of any β-lactam derivatives with polyhexamethylene biguanide hydrogen carbonate. Said novel compounds are suitable as an antibiotic. | 02-17-2011 |
| 20110159273 | METHOD FOR COATING SURFACES WITH MICRO- AND NANOPARTICLES WITH THE AID OF PLASMA METHODS - The invention relates to a method for coating surfaces with micro- and nanoparticles, the micro- and nanoparticles being chemically bonded to the surface, comprising the steps of pre-treatment of the surface with a plasma method, simultaneous or subsequent application of the micro- and nanoparticles to the surface, and subsequent fixation of the micro and nanoparticles on the surface using a plasma method, characterized in that the fixation of the micro- and nanoparticles takes place with the aid of anisothermal plasmas, the median electrical energy of which lies in the range of the bond dissociation energy of the micro- and nanoparticles, thus allowing the strength of the chemical bond between the surface and the micro- and nanoparticles to be variably set. | 06-30-2011 |
