Abstract: A drying nozzle (1) for drying a peripheral portion of an ophthalmic lens (CL), in particular a contact lens, comprises an inlet (30) for the supply of a pressurized gas and a continuous annular outlet gap (11) having a predetermined width (W) through which the pressurized air is capable of being supplied to the peripheral portion of the ophthalmic lens (CL).

Abstract: The present invention relates to a process for preparing colorless polyisocyanates, in particular for reducing the color of polyisocyanates.

Abstract: A test coupler for supplying a device under test with test signals contains a first coaxial connector, a waveguide port, and a first strip conductor. Test signals of a lower frequency range are supplied to the first coaxial connector. Test signals of an upper frequency range are supplied to the waveguide port. The test coupler guides the test signals on the first strip conductor to the device under test.

Abstract: Electrical switching device, especially a high-frequency switching device, with at least one oblong electrical switching element, which is arranged with one contact end between two fixed-contact elements spaced a transverse distance from one another and can be moved by two adjustment elements forming a transverse movement drive transversely to a longitudinal direction optionally towards the one or the other fixed-contact element. The adjustment elements are disposed laterally alongside the switching element and can be moved transversely to and from the switching element. In order to improve the transverse movement drive for the switching element, the switching element-comprises magnetic material, wherein the adjustment elements are formed by magnets.

Abstract: In a directional coupler with two coupled lines arranged in a flat chamber of an enclosed metal housing within the coupling region side-by-side in the longitudinal direction and at a spacing distance from one another, of which the ends are connected to connecting ports attached at the sides of the metal housing, these coupled lines include flat, sheet-metal strip conductors, which are arranged within the coupling region with their broad sides facing towards one another side-by-side at a spacing distance and held by several support elements made of insulating material in a cantilever manner at a spacing distance from the opposing internal walls of the flat metal-housing chamber within the latter. In this context, at least one strip conductor is curved relative to the opposing strip conductor in such a manner that the spacing distance of the strip conductors in coupling region increases starting from the beginning of the coupling region approximately exponentially up to the end of the coupling region.

Abstract: An electrical switching device, especially a high-frequency switching device, comprising an elongate electrical switching element, a contact end of which is disposed between two opposite contact elements that are transversally spaced apart from each other. The switching element can be selectively moved perpendicularly to the longitudinal direction thereof towards one or the other opposite contact element by two adjusting elements that are located on both sides next to the switching element. In order to eliminate or at least reduce frictional processes and the risk of the electrical contact being damaged by abrasion, the switching element is made at least in part of magnetic material while the adjusting elements are formed by two magnet assemblies, the magnetic force of one magnet assembly or the other magnet assembly being selectively reducible or increasable.

Abstract: The present invention relates to a mold half for making an ophthalmic lens, in particular a contact lens, wherein the mold half comprises a release sheet removably arranged on the mold surface of said mold half to separate a lens forming material from the mold surface, as well as to a method for applying a removable mold release sheet to said mold half. The mold half of the invention comprises a vacuum means to removably attach said release sheet to said mold surface, and preferably the mold half further comprises a pinch-off rim for forming the edge of said ophthalmic lens.

Abstract: The present invention relates to a novel process for preparing colorless, isocyanurate group-comprising polyisocyanates of (cyclo)aliphatic diisocyanates.
