Abstract: Multiphase flowmeter aperture antenna transmission and pressure retention are disclosed herein. An example apparatus includes at least one radiating element to transmit or receive an electromagnetic signal along a measurement plane orthogonal to a direction of flow of the fluid in the vessel; a pressure retaining member to prevent fluid from entering the aperture antenna assembly through a measurement window of the aperture antenna assembly, at least a portion of the pressure retaining member to separate the radiating element and the fluid; and a metal housing with or without slits, the pressure retaining member to be at least partially within the metal housing, the radiating element to be coupled to the metal housing.

Abstract: A baking pan includes a lower pan part having a respective periphery and at least one raised area spaced from that periphery. The pan further includes an upper pan part having a respective periphery, the upper pan being removably connected to the lower pan part about the periphery of the upper pan part. This pan is utilizable in a cooking method including a dough proofing stage and a baking process. The baking process in turn incorporates a first cycle of baking and steaming and a second cycle of baking only. The baking pan has a water-receiving internal chamber and a proofing and cooking chamber communicating with the internal chamber via one or more perforations in an upper surface of the baking pan. The proofing and cooking chamber is formed by a cover or lid placed over the upper surface of the baking pan.

Abstract: A diver's mask has a body having a pair of symmetrically opposed first spaces defined therein, a cover detachably engaged with the body and having a pair of symmetrically opposed second spaces defined therein and respectively corresponding to the pair of first spaces, a pair of symmetrically opposed frames each detachable with and slidable onto the cover and a pair of symmetrically opposed lenses each detachably secured between the frame and the cover. Due to the slidable relationship between each of the frames and the cover, a user is able to save time assembling and disassembling elements and that the relationship between elements are able to maintain in a watertight manner.
