Abstract: A non-venting propellant filling and sealing valve (10) is seated in a propellant filling hole (14) in a bottom wall (11) of a container, and permits pressurization of a container through the hole and thereafter seals the container. The valve (10) includes an umbrella sealing portion (18), a stem portion (20) and shoulder portions (25a, 25b) in a collar (24) around the stem portion (20). The umbrella sealing portion is resilient and is adapted to separate from the interior surface (46) of the bottom wall (11) of the container during pressurization and then make a generally annular seal with this surface around the hole (14). The stem portion (20) positions the umbrella sealing portion (18) around the filling hole and both it and the collar (24) have axially extending grooves therein for con- - ducting pressurizing fluid to the interior of the container. The shoulder portions (25a, 25b) of the collar (24) bear against the outer surface (42) of the bottom wall (11) to prevent the valve (10) from being blown into the container during pressurization and cause the umbrella sealing portion (18) to engage the interior surface (46) of the bottom wall. When pressurization is completed, the source of fluid is removed and the pressure inside the container, being greater than ambient, causes the umbrella sealing portion (18) to form an annular, fluid- tight seal with the interior surface (46) around the filling hole (14).

Abstract: A dehydrating screw press by which an advancing product to be deshydrated is pressed, by the rotating movement of one or more screw elements with a conical shaft (1) and a conical spiral (2) operating in a corresponding space up to the wall of a filtering cage (3). As the increasing diameter of the spiral (2) conforms to the like reduction of the shaft section (4), the use of the helical elements fitted side by side allows each spiral to operate with a profile extending up to the other helical element wall. Therefore, non-intermeshing zones are avoided during the dehydrating phase in the intermediate space. As the two pressing elements are rotated in opposite directions, rotation of the pressed material is avoided, thus advancing the product in an axial direction. The filtering cage used for a press with two helical elements shows a confirmity with two components (5 and 6) interconnected on lines (7 and 8) at the intermeshing area of the two spirals.

Apart from a motor drive device (1-4), an encoding device (12a-12c; 24a-24c) for the indexing or pre-selection of a specific optical component to be brought into operating position, and locating means (7, 7a; 8) for positioning the optical component in operating position, the rotating device has, in additiion, marking and control means (13; 13a), with the aid of which the speed of the turret can be controlled as a function of its particular relative position. In particular, it is possible with the device described to bring a high-speed motor-driven turret (5) into a set location, there taking place shortly before attainment of this operating position a controlled braking of the rotational speed of the turret (5). Moreover, the microscope turret (5) is decoupled from the motor drive device (1-4), which comprises an electromotor (1) and a tachometer generator (1a), so that the exact attainment of the operating position takes place in a purely mechanical fashion through locating means (7, 7a; 8). Moreover, a procedure is given for controlling the speed of the rotating turret device.
