Abstract: The disclosed embodiments describe force-transmitting devices for use in gravimetric measuring instruments. The force-transmitting devices scale the force from a calibration weight to facilitate calibration and weighing. The devices comprise unidirectional coupling elements. The unidirectional coupling element comprises coupling element parts. The elements may be adapted to transmit only a tensile force or only a compressive force to a measurement transducer. Adapting the unidirectional coupling element to transmit one type of force or the other may be done by selecting an appropriate arrangement of coupling element parts. The coupling element parts are adapted to transmit force along a midline axis by either a projection and v-shaped groove coupling or projections on the first part mated with surfaces on the second part adapted to receive and guide the first part.

Abstract: The invention relates to a method and device for the treatment of glaucoma, though insertion of an implant into the lumen of the Schlemm's canal to realize proper drainage of the aqueous humor, which implant is brought into its position in the Schlemm's canal by means of a catheter having a distal and a proximate portion and provided with a number of pores through which a gaseous or fluid medium which comes from a pressure source can emerge during insertion of the catheter carrying the implant into the Schlemm's canal, and while the catheter is being inserted into the Schlemm's canal the gaseous or fluid medium is released under pressure thereby expanding the Schlemm's canal and the implant and upon releasing the implant at its determined location, the catheter can be withdrawn from the Schlemm's canal.

Abstract: A method and apparatus for removing components from a gas stream by feeding the gas stream into a pre-condensation unit to produce a gas stream at a lower intermediate temperature and feeding this intermediate temperature gas stream into a cryogenic condensation unit where a lower predetermined final temperature is achieved. This final temperature gas stream is directed back to the pre-condensation unit to assist in cooling the gas stream entering this unit.

Abstract: A parallel-guiding mechanism has a vertically movable parallel leg that carries a weighing pan. The movable parallel leg is connected by two essentially horizontal parallel guides to a stationary parallel leg installed in a balance, wherein elastic flexure pivots are formed at the ends of the parallel guides. Incisions that reduce the material strength of the parallel leg in at least one appropriate location define at least one adjustment domain, thus forming a deformation zone which is plastically deformed through application of an adjustment force. In this manner, a corner load error of the parallel-guiding mechanism is corrected.

Abstract: In a parallel-guiding mechanism, a stationary parallel leg surrounds a movable parallel leg. The movable parallel leg is connected to the stationary parallel leg and guided in vertical movement by first and second parallel-guiding elements, fastened respectively to the upper and lower end portions. The movable parallel leg can be connected to a load receiver and to a force-measuring cell through a force-transmitting connection in order to transmit the weighing load. Intermediate to, and connecting, the respective end portions is a tilt-adjustment feature, by which the end portions are tilt-adjusted relative to each other about at least one tilt axis to correct a corner load error. The tilt-adjustment feature is provided by at least one of: a pair of bending zones, a spherical joint and a ring-shaped constriction.

Abstract: Process for the preparation of tetrahydropterin and tetrahydropterin derivatives by hydrogenating pterin and pterin derivatives with hydrogen in the presence of a hydrogenating catalyst, in which the hydrogenation is carried out in a polar reaction medium and metal complexes that are soluble in the reaction medium are employed as the hydrogenation catalysts.
