20090162473 | Neck Block Cooling - A neck block of a moulding tool for the production of a hollow body preform by means of injection moulding, wherein the neck block has a main body with a shaping surface which is adapted to the external contour of a neck portion of the hollow body preform to be produced and is provided to come into contact in the injection moulding operation with the neck portion of the hollow body preform, wherein furthermore there is provided at least one cooling passage for a cooling fluid which at least portion-wise extends substantially parallel to the shaping surface. The neck block is further provided with an inlet and an outlet and an inlet passage and an outlet passage which connect the inlet and the outlet respectively to the cooling passage. The cooling passage is arranged closer to the shaping surface than the inlet and the outlet. The cooling passage has at least one portion which extends substantially parallel to the shaping surface and which extends within the main body so that the walls thereof are formed by the main body, and a connecting portion which adjoins said portion and the walls of which are formed in part by the main body and in part by a closure element fitted onto the main body. | 06-25-2009 |
20090212459 | Method and System for Post-Treating Preforms - The invention concerns a system for the post-treatment of preforms ( | 08-27-2009 |
20100007048 | METHOD FOR THE PRODUCTION OF A MULTI-LAYER PREFORM AND NOZZLE THEREFOR - A melt feed device for an injection molding apparatus having at least one nozzle element connected both to a first hot runner and a second hot runner for feeding both the first melt and the second melt into an injection molding mold. The nozzle has three substantially concentrically arranged feed passages, wherein the innermost and the outermost feed passage are in communication with the first hot runner and the central feed passage is in communication with the second hot runner. A closure element is provided that can be reciprocated between a first position in which the closure element closes all feed passages, a second position in which the closure element opens the outermost feed passage but closes the other two feed passages and a third position in which the closure element opens all feed passages. The invention also includes process and molds using the device. | 01-14-2010 |

20130287883 | Injection-Moulding Machine with a Shut-Off Needle - This relates to an injection-moulding machine comprising a hot runner for feeding a melt into a mould, a shut-off needle for closing or opening the hot runner, a piston connected to the shut-off needle, dividing the housing into first and second chambers, and a covering plate with a first and a second fluid | 10-31-2013 |
20130287886 | Injection-Moulding Machine - An injection-moulding machine comprising a hot runner, arranged in a manifold, for feeding a melt into a mould, a shut-off needle for optionally closing or opening the hot runner, a piston connected to the needle, is arranged in a housing with an opening and to which a fluid can be applied from both sides, and a covering plate having two fluid feeds, into the opening wherein the covering plate, the hot runner manifold and the housing are arranged in such a way that, at a first temperature of the manifold, a distance remains between the housing and the covering plate and, at a second higher temperature the thermal expansion of the manifold and/or housing causes the housing to come into contact with the covering plate, closing the opening. In a further embodiment, a flexible seal is provided between the housing and the covering plate. | 10-31-2013 |
20150044324 | INJECTION MOLD PLATE AND INJECTION MOLD HAVING SUCH AN INJECTION MOLD PLATE - The present invention relates to an injection mold plate for use in an injection mold for producing molded articles, comprising a plurality of handling elements arranged in columns and rows, wherein the distance r between adjacent handling elements within the rows is greater than the distance s between adjacent handling elements within the columns. According to the invention, in order to provide an injection mold plate of the type mentioned above for which the distance between adjacent handling elements can be reduced without impairing the generally required heating channel, it is proposed that a row of handling elements is formed by two groups of handling elements, wherein the following applies to the distance x between the group: z=r(1+a/n), wherein r is the distance of the handling elements within a group and n,a=IN with n>1. | 02-12-2015 |

20110149276 | Method of Detecting a Particle and a Lithographic Apparatus - A detector detects radiation from a mask to form an image, but the focal plane of the image is in front of the mask. Any particles arranged on the mask will be in focus. However, the pattern on the mask will be out of focus. It is therefore possible to detect the existence and location of particles on a mask having an arbitrary pattern. The depth of field of the detector is small and the focal plane is no further from the surface of the patterning device than two times the depth of field. | 06-23-2011 |
20120013882 | ILLUMINATION SYSTEM, LITHOGRAPHIC APPARATUS AND METHOD OF FORMING AN ILLUMINATION MODE - An illumination system of a lithographic apparatus includes a plurality of reflective elements arranged to receive radiation from a radiation source, the reflective elements being movable between different orientations. In the different orientations, the reflective elements direct radiation towards different locations at a reflective component in a pupil plane of the illumination system, thereby forming different illumination modes. Each reflective element is moveable between a first orientation, which directs radiation towards a first location the pupil plane, and a second orientation, which directs radiation towards a second location in the pupil plane. The first orientation and the second orientation of the reflective element are defined by end stops. | 01-19-2012 |
20140160453 | RADIATION SOURCE - A radiation source includes a nozzle configured to direct a stream of fuel droplets along a trajectory towards a plasma formation location; a laser configured to output laser radiation, the laser radiation directed at the fuel droplets at the plasma formation location to generate, in use, a radiation generating plasma; and a catch configured to catch fuel droplets that pass the plasma formation location. The catch includes a container configured to contain a fluid; a driver configured to drive the fluid, to cause the fluid to move; the catch being configured such that the fuel droplets are incident on that moving fluid. | 06-12-2014 |
