20150314375 | DRILL CHUCK - A drill chuck having a chuck body that has a receptacle on its axially rearward end, having clamping jaws that can be moved relative to the chuck axis, and having a clamping sleeve that serves to move the clamping jaws. An adapter body can be placed in the receptacle and coupled in a torque-transmitting manner, which adapter body has an adapter receptacle for detachable connection to the drilling spindle of a power drill and has, in the wall of the adapter receptacle, at least one detent element that can be moved by a release sleeve. | 11-05-2015 |
20150273678 | DRILLING DEVICE AND FRICTION CLUTCH FOR A DRILLING DEVICE - A drilling device, which is adjustable at least between a clamping configuration, a drilling configuration and a screwing configuration, includes a machine housing and a machine spindle, which is drivable with the aid of a motor. A drill chuck having a jaw holder, in which clamping jaws are guided, which are adjustable with the aid of a threaded connection provided between an entrainer and a threaded sleeve is provided. A drill spindle, which is drivable by the motor via a planetary gear set, is disposed on the side facing the machine spindle and includes a sun wheel, a planet carrier, which carries at least one planet wheel, and a ring wheel, which has at least one cam, which interacts with at least one clutch element, which is fixed with respect to the ring gear in the drilling configuration. The at least one clutch element is supported with respect to the ring wheel, movable against a clamping spring force of a clamping spring, and the at least one clutch element is movably supported against a screw spring force, in the screwing configuration, the screw spring force resulting from a series connection of the clamping spring and a screw spring. | 10-01-2015 |
20150273644 | CHUCK - A chuck having a chuck body in which clamping jaws are movably carried in radially extending guide seats. The clamping jaws include a base jaw and a top jaw arranged on the base jaw in a tongue and groove, and include at least one sensor for sensing the clamping force, whereby the sensor is associated with the tongue and groove. | 10-01-2015 |
20150251252 | DRILL CHUCK - A drill chuck having a chuck body, having a clamping sleeve with a conical basic shape that can rotate about the chuck axis of the chuck body, by the rotation of which clamping sleeve a plurality of clamping jaws can be moved relative to the clamping body. The clamping sleeve is made in two parts, having a conical, metallic outer sleeve, having a conical, inner sleeve made of plastic, wherein the outer sleeve has a cylindrical subsection on its inner circumference for radial centering of the outer sleeve on the inner sleeve. A clamping sleeve and a method for producing knurling on the clamping sleeve are also provided. | 09-10-2015 |
20150130144 | DRILL CHUCK - A drill chuck having a chuck body, which is produced from plastic, in particular from fibre-reinforced plastic, and has a spindle holder and a tool holder and in which clamping jaws that can be adjusted by a threaded ring are guided. The chuck body has a securing ring on an outer circumference in a region of the tool holder. | 05-14-2015 |
20100151010 | MEDICAMENT IN A MULTILAYER FORM - The invention relates to a medicament in a multilayer form, containing a) a core with a pharmaceutical agent, b) an inner coating, 50 to 95 percent by weight of which arc composed of a (co)polymer comprising 95 to 100 percent by weight of radically polymerized vinylic monomers with neutral side groups and 0 to 5 percent by weight of monomers with anionic side groups, c) an outer coaling made of a copolymer comprising 75 to 95 percent by weight of radically polymerized C | 06-17-2010 |
20090288506 | POWER ACTUATOR - A power actuator is provided for a door latch. A transfer lever within the housing is selectively coupled to a motor-driven worm gear via a lost motion connector. Engaging the motor moves the transfer lever between a locked and an unlocked position, actuating an output lever mounted to a spline on the transfer lever. The worm gear returns to a neutral position when the motor is disengaged, leaving the transfer lever in either the locked or unlocked positions. Manually moving the output lever causes the transfer lever to move between its locked and unlocked positions without back-driving the worm gear. A toggle mechanism prevents the transfer lever from accidentally moving or only moving partially between the locked and unlocked positions. | 11-26-2009 |
20090215962 | MULTILAYERED FILM MADE OF (METH)ACRYLATE COPOLYMER AND POLYCARBONATE - The invention relates to a multilayer film encompassing at least one upper layer a) and one middle layer b) composed of (meth)acrylate copolymers, and also a backing layer c) composed of polycarbonate, where the upper layer a) comprises a light stabilizer and is composed of a (meth)acrylate copolymer which can form semicompatible mixtures with the polycarbonate of the backing layer c), where a test specimen produced from a mixture composed of 20% by weight of (meth)acrylate copolymer and 80% by weight of polycarbonate has a tensile strain at break of at least 75% (ISO 527-2) at 23° C., the middle layer b) comprises a dye and, where appropriate, a light stabilizer, and is composed of an identical or different (meth)acrylate copolymer which can form semicompatible mixtures with the polycarbonate of the backing layer c), where a test specimen produced from a mixture composed of 20% by weight of (meth)acrylate copolymer and 80% by weight of polycarbonate has a tensile strain at break of at least 75% (ISO 527-2) at 23° C., and the backing layer c) is composed of polycarbonate which can, where appropriate, comprise up to 30% by weight of the material of the layers a) and b). The invention also relates to the production and uses of the multilayer film, and also to semicompatible polymer mixtures composed of (meth)acrylate copolymers and polycarbonate. | 08-27-2009 |
20090176928 | SUBDUEDLY COLORED, INFRARED REFLECTING PLASTIC COMPOUND - The invention relates to subduedly colored (brown, gray, black, green), infrared reflecting PMMA compounds which can be applied to other plastic compounds as an IR barrier layer | 07-09-2009 |
20090149674 | METHOD FOR THE CONTINUOUS PRODUCTION OF ALKYL AMINO ACRYL AMIDES - The invention relates to a method for the continuous production of alkyl amino acryl amides by reacting alkyl acrylates with high-boiling amines. A specific preparation technique is used in order to achieve hitherto unobtainable product qualities. Very high spatial, temporal and overall yields can also be obtained. | 06-11-2009 |
20090041842 | Partly Neutralised Anionic (Meth) Acrylate Copolymer - The invention relates to a partly neutralised anionic (meth)acrylate copolymer consisting of radically polymerised units containing 25-95% by weight (meth)acrylic acid C | 02-12-2009 |
20080293854 | Plastisols Based on a Methylmethacrylate Copolymer - The invention relates to plastisol systems with improved properties. | 11-27-2008 |
20080226876 | Method for Producing a Core Material Reinforcement for Sandwich Structures and Said Sanwich Structures - A sandwich structure reinforcement carried out by a gripper, which pierces the sandwich structure or the core material, only at one side, thereby obtaining a hole penetrating through, e.g., a polymer rigid foam. At the opposite side, the gripper catches the reinforcing structure (for example a sewing thread, pultruded fiber-plastic composite rods) and inserts the reinforcing structure into the sandwich structure during back movement thereof. The through hole is additionally enlargeable by the reinforcing structure, thereby making it possible to obtain an important fiber volume part in the through hole of the core material. | 09-18-2008 |
