Abstract: A transfer device is designed for contamination-protected transfer of flowable process material between a first container and a second container. The transfer device includes a guide tube having an axial passage for the flow of the process material, which has a connection at one end and terminates with a tube edge at the other end. A transfer unit opens into the guide tube, which allows engagement with the guide tube. A tubular liner supply having a plurality of peelable useful sections, each provided with a first crimp, is stored on the transfer unit. The useful sections can be used to isolate liner remnants from previous transfer operations for disposal. A first tensioner and a second tensioner are arranged circularly on the guide tube and concentrically to each other, which serve for temporary sealed fixing of residual ends and open ends of new liner pieces originating from inner liners from the second containers.

Abstract: A method for transferring process material between a first container and a second container has, as its essential constituent parts, at least one first tensioning unit, which has a first tensioner and a second tensioner, which can be actuated independently of one another, and also a tubular liner piece, which extends indirectly between the containers in order to seal off the transition between the containers from the exterior. The tensioning unit has fixed in it, temporarily, the near end portion of the liner piece and the near end portion of a tubular liner remainder left over from a previous transfer operation. In specific applications, a transfer means is installed between the containers. The process material is usually of a sensitive nature—e.g. a pharmaceutical component—and must be neither contaminated by the exterior surroundings nor pass into the surroundings. The containers are typically constituent parts of a production installation, such as big bags, steel containers or drums.

Abstract: A valve (1) for an explosion protection apparatus comprises a pipe element having a pipe wall (11). Two slides (15, 15') can be pushed from the outside into the pipe element, through in each case one opening (111, 111') in the pipe wall (11). An expandable diaphragm (14) is arranged on the inside of the pipe wall (11) and forms an inner pipe which can be closed by means of the slide (15, 15') by mutually opposite diaphragm regions being pressed against one another. The expandable diaphragm which forms an inner pipe does not provide any accretion points for solid particles of product-loaded gas flow to collect on.

Abstract: An explosion protection apparatus for installation in potentially explosive industrial installations for the purpose of automatically preventing a pressure wave and/or flame breaking through from a potentially explosive installation part to adjacent installation parts, has a sensor for explosion identification, which can be arranged in the potentially explosive installation part or can be connected to it. The sensor is electrically connected to an initiation device (1) which, in its basic state, holds a closing device (3) in its open position via an interlocking device (2) and with the aid of an active magnetic field of an electromagnet (5), and can be operated by sensor signals. The closing device (3) is prestressed such that, after operation of the initiation device (1), it is moved to its closed position. It can be arranged between the installation parts to be protected and the potentially explosive installation part.
