Abstract: A vertical rod baffle heat exchanger may be used for heat removal, condensation operations, electricity generation, petrochemical plants, waste heat recovery, and other industrial applications. The vertical rod baffle heat exchanger may include a shell; a tube-sheet; a tube bundle having a plurality of heat exchange tubes extending in an axial direction; six or more longitudinal partition plates; and a plurality of rod baffle rings provided along an axial length of the plurality of heat exchange tubes. At least one longitudinal partition plate may be a notched longitudinal partition plate. The plurality of rod baffle rings may have lateral rod baffles and longitudinal rod baffles. The lateral rod baffles and the longitudinal rod baffles may pass through gaps between every two adjacent tubes of plurality of heat exchange tubes. The lateral rod baffles may pass through openings in the notched longitudinal partition plate.

Abstract: A differential cylinder for a hydromechanical drive for actuating an electrical switch, for example a high-voltage switch, is disclosed which includes a first pressure region for applying a working pressure, a second pressure region, and a piston which is capable of moving in a movement region and which is movable depending on a pressure difference between the first and second pressure region. A damping device is provided which, in the event of a movement of the piston in the direction of the second pressure region, provides damping with respect to the movement of the piston in a section of the movement region, wherein the damping is adjustable.

Abstract: Systems and methods of user interface for facilitation of high level generation of processor extensions. In accordance with a method embodiment of the present invention, an instruction format is accessed at a graphical user interface. A programming language description of a computation element for an execution unit of the processor extension is accessed. A representation of a hardware design for the processor extension comprising the instruction format and the computation element is generated.

Abstract: The method for coding live images in microscopy makes possible the recording of a first complete image (251) that depicts a portion of a microscopic preparation (14a). A first coded complete image (200) is generated therefrom and is stored in a buffer memory (27). The first coded complete image (251) can moreover be output, for example, on a monitor. When a second complete image (252) is recorded, only a part is processed and transmitted. That part corresponds to the offset of an X-Y stage (12). The coordinates of the portion of the second complete image (252), and further control data, are transferred to a control data decoder (26). A correspondingly assembled and coded complete image (210) is generated in an image assembler (32), the at least one coded partial image (220) and the preceding coded complete image located in the buffer memory (27) being used.

Abstract: The invention is a pressure responsive shut-off valve including a valve housing that defines a fluid inlet and a fluid outlet separated by a valve seat. A valve closure accommodated by the valve seat moves between open and closed positions to control fluid flow between the inlet and outlet. Controlling the valve is a valve operator including a pressure responsive piston that moves between a set position in which the valve closure is separated from the valve seat and a release position in which the closure is seated on the seat to prevent fluid flow between the inlet and outlet. Retaining the piston is a magnetic plunger that defines an activating volume communicating with the inlet and establishing on one face of the piston a fluid pressure forcing the piston toward its release position, and a reference volume communicating with the inlet and establishing on the opposite face of the piston a reference volume.

Abstract: A combined solenoid operated valve and shut-off device including a valve housing defining a fluid inlet, a fluid outlet, and a valve seat therebetween. Located within the housing is a valve closure movable between a closed position in which fluid flow between the inlet and outlet is prevented and an open position wherein such flow is permitted. Controlling movement of the valve closure is a valve operator that includes a magnetic plunger for cycling the valve closure between open and closed positions in response to an electrical signal and a shut-off mechanism activatable to lock the valve closure in its closed position in response to a predetermined fluid pressure at the inlet. After activation of the shut-off mechanism, reopening of the valve to initiate fuel flow between the inlet and outlet requires actuation of a manual reset device.

Abstract: A high pressure safety valve which automatically closes when high pressure conditions exist. The high pressure valve includes a diaphragm valve and a snap acting assembly connected to the diaphragm valve which acts to snap it closed when a high pressure condition is detected. The safety valve of the present invention may also include a relief valve which opens when the diaphragm valve closes to relieve pressure at the outlet of the safety valve. In addition, the safety valve of the present invention can be manually reset only after the high pressure condition has been corrected.
