A capsule (1) for obtaining beverages is shown, comprising a side wall (5) and an entry surface (6) for the entrance of water under pressure into the capsule (1), wherein the side wall (5) and the entry surface (6) form the containment volume (V) for containing the infusion product (P). The entry surface (6) comprises one or more reduced thickness areas (3) so that, letting water under pressure flow against the entry surface (6), the one or more reduced thickness areas (3) open, so as to allow water under pressure to enter the capsule (1). The capsule (1) may further comprise one or more strengthening ribs (4) provided on the entry surface (6) so as to strengthen the entry surface (6) and simplify the opening of the reduced thickness areas (3) when water under pressure flows against the entry surface (6). A method for the production of beverages is also shown, comprising the following step: flow of water under pressure against the entry surface (6) of the capsule (1) so as to open the reduced thickness areas (3) of the entry surface (6) so as to allow the water under pressure to enter the capsule (1).
Abstract:
Ein induktives Bauelement, insbesondere eine Speicherdrossel, besitzt einen Haltebereich im Kernmaterial, der eine Auflagefläche aufweist, die der Kontur zumindest eines Teils einer Windung nachgebildet ist. Daher ergibt sich eine bessere mechanische und thermische Ankopplung der frei tragenden Wicklung an das magnetische Material des Kerns.
Abstract:
Es wird eine Schlauchkupplung (100) offenbart, die auf Grund konstruktiver Maßnahmen mit einer geringen Zahl an Einzelkomponenten (100a, 100b, 100c) vorgesehen werden kann, so dass sich eine hohe Zuverlässigkeit beim Betrieb ergibt und auch eine einfache Handhabung beim Ankoppeln und Abkoppeln erreicht wird. Insbesondere ist die Schlauchkupplung durch Verdrehung innerhalb eines kleinen Winkelbereichs verriegelbar, ohne dass bewegliche Komponenten dafür erforderlich sind. In einigen anschaulichen Ausführungsformen wird die Schlauchkupplung (100) als Kupplung in Fluidleitungen im Agrarsektor, beispielsweise in Milchleitungen, verwendet.

The semiconductor laser comprises a front facet and a back facet. The front facet and the back facet define an internal laser cavity. The internal laser cavity comprises a laser active medium. The partially transmitting wavelength selective light reflector has a peak reflectivity within a gain bandwidth of said laser active medium. The wavelength selective light reflector and the back facet define an external laser cavity. A roundtrip time of light in the external laser cavity is about 20 nanoseconds or less. A full width half maximum bandwidth of the wavelength selective light reflector is adapted to accommodate at least 12 longitudinal modes of the internal laser cavity and at least 250 longitudinal modes of the external laser cavity.
