Abstract: Flameproof electrical switch gear (1) has a busbar channel (2) and two or more pressure-proof housings (7) which are to be connected electrically to the busbar channel by means of plug-in devices. The pressure-proof housings (7) can be conveyed on a supporting device (10) by means of a positioning drive (11). A door (15), to be opened by vertical movement, of the pressure-proof housing (7) cannot be opened until the pressure-proof housing (7) has been conveyed sufficiently that the contact elements of the plug-in device (4) have been separated and the door (15) has been moved out of the region of effectiveness of an upper protection device (14). When the pressure- proof housing (7) is completely taken away, a push button (17) fitted to the socket part (5) of the plug-in device (4) is operated to disconnect a supplying switching unit and thus to ensure that the installation is no longer live. <IMAGE>

Abstract: There is disclosed herein an apparatus and method for generating a first signal related to the rate of change of a second signal. In particular, a system is disclosed for generating a velocity signal in a sampled data servo system. The apparatus uses three track and hold amplifiers one of which is also a difference amplifier to sample the position error signal at selected times. A "present" track and hold amplifier samples and holds the position error signal during the current frame. After this is done, during the same frame, a "summing" track and hold amplifier having its difference inputs coupled to the outputs of the "present" track and hold amplifier and to a "previous" track and hold amplifier samples the difference between the present position error signal and the value of the position error signal during the previous sample frame. This difference divided by the sample period gives the velocity. After the difference value is sampled, the "previous" track and hold amplifier sample is updated to the amplitude of the position error signal during the current frame in preparation for the calculation during the next frame.

Abstract: Device for the injecting of liquid manure into the ground. A very narrow cut is made in the ground of for example grassland by vertically disposed pairs of blades (7). Directly at the contact point between the blades debouches a nozzle (13) that is connected to a reservoir for liquid manure. Thus achieved is that the liquid manure is introduced directly into the narrow cut in the ground, after which the cut is closed up again by a following furrow closer. This prevents environmentally damaging ammonia escaping from the liquid manure into the surrounding air.

Abstract: A gas flow diverter receives large volumes of hot gazes from a gas turbine and has a blade adapted to close either the outlet port to a heat recovery steam generator or the outlet port to the stack. Each port is surrounded by an open channel the two side walls of which are each provided with a seal with both exposed, one beyond the other. The surfaces of the blade are stainless steel cladding and are connected through insulation to a reinforcement in a manner permitting but confining the expansion of the cladding. The frame has a border providing first and second ledges on each side which are spaced and positioned so that each may engage a different one of the two seals bordering an outlet port when closed thus establishing the channel as a closed passageway surrounding the closed port which may be sealed against leakage by die-charging sealing air into it. The blade is shifted between its two operative positions by means of a reversible drive including toggle joints connected to the blade reinforcement by a unit which is shiftable in response to forces exerted by the expanding or contracting toggle joints. <IMAGE>

Abstract: An apparatus for casting an agarose gel and for conducting an electrophoresis process is disclosed. An electrophoresis tank (106) supports a gel casting deck (202) having open ends (210) which are sealed by wedge dams (302) to form a cavity for containing the molten agarose as it gels. The wedge dams (302) are pulled downward by gravity into wedge-shaped slots. The weight of the wedge dams (302) in the wedge slots presses the wedge dams (302) against the open ends (210) of the gel casting deck (202) so as to provide a substantially fluid-tight seal. The gel casting deck (202) has sidewalls whcih are slanted toward one another in the upwards direction so that when the gel is submerged in buffer solution during electrophoresis, the gel's tendency to float is substantially impeded. The combs (408) which form wells in the gel are referenced to the sides (208) of the gel casting deck (202) itself so as to ensure uniformity and accuracy of well depth. Safety features prevent the electrophoresis tank from functioning if removed from its protective housing.
