Abstract: A time stamp for insertion into a mould for metal or plastics processing has a basic body which can be inserted into the mould, and has an insert designed as a screw arranged rotatably in the basic body. The insert, in order to maintain its rotary position relative to the basic body, is retained in the basic body such that its shank end is in threaded engagement with a spring-pretensioned holding part arranged in the inner region of the basic body; thus a shoulder of a head portion of the insert can be pressed constantly against an annular radial step formed on the basic body.

Abstract: A temperature compensated microwave filter has end caps and irises that each contain a projection that extends into a cavity to reduce the volume change of the cavity that would otherwise occur with changes in temperature due to an expansion or contraction of the side walls.  The end caps and irises are formed from a single material.  The material has a more positive coefficient of thermal expansion than the coefficient of thermal expansion of the side walls of each cavity.  While one material is used to make up each end cap or iris, it is not necessary that the same material be used for all of the end cap and iris components.

Granted: 2002-06-11
Abstract: La présente invention présente une méthode de dosage par protection contre la formation d'un produit d'addition impliquant l'utilisation d'un partenaire de liaison marqué et d'un ligand modificateur de signal. Ledit ligand modificateur de signal peut, de préférence, modifier la capacité d'un traceur ne faisant pas partie d'un complexe partenaire de liaison-analyte de produire un signal détectable, par rapport à sa capacité de modifier un signal produit par un traceur faisant partie d'un complexe partenaire de liaison-analyte. La présence ou la quantité d'analyte peut être déterminée par détection du signal produit par un traceur non modifié. Ladite méthode de dosage par protection contre la formation de produit d'addition offre une grande souplesse d'application. Par exemple, la modification du signal peut être effectuée dans un large éventail de conditions (par exemple pH, température et force ionique), et la modification du traceur tout comme le déclenchement du signal peuvent être exécutés à température essentiellement constante pour obtenir un degré de sensibilité élevé.
