Abstract: High-strength aluminum alloys and other hot-short-sensitive alloys can be extruded at rapid rates through a cooled, double reduction die (3) without hot-short cracking or scoring caused by die pickup. A primary reduction die (4) has a long, cooled primary land (5) and is followed by a secondary reduction die (6). A metal billet (15) may be extruded through the primary die (4) at about the solidus temperature of its lowest melting phase, then cooled as it passes through the primary die land (5) to reduce or maintain the temperature below the solidus temperature and, finally, the primary extrusion is reduced in cross section in the secondary die (6) by about 2-50%. The temperature, the back pressure caused by the second reduction, and the low friction through the primary land (5) contribute to eliminate hot-short cracks and minimize serious pickup scoring at surprising rates of at least about 18 meters per minute (60 ft/min) for 2024 aluminum rod.

Abstract: The multi-layer ceramic capacitor structure (1) is capable of embodying multiple capacitors of various maximum voltage and capacitance rating. The structure (1) features a ceramic body (2) including multiple sections (3) having a dielectric element (4A, B, C) and companion plate (5A, B, C) of one or more types, the types defined by the number and placement of plate tabs (8A, B, C). The sections (3) are aligned in the body (2) such that the plates (5A, B, C) are located at displaced intervals in the direction of the body length while the plate tabs (8A, B, C) are located at displaced intervals in the direction of the body width and exposed at a common body face (11). Grooves (17) are provided in the common face (11) to align tabs (8A, B, C) in groups and to maintain the groups separated. Grooves (17) have the effect that the maximum voltage the structure (1) can withstand is not reduced due to mis-alignment of tabs (8A, B, C) during formation of body (2). Buses (12A, B, C) interconnect the tabs (SA, B, C) and plates (5A, B, C) in groups at common face (11). By selectively connecting the buses (12A, B, C), one or more capacitors may be formed in body (2). The method features steps for grooving the common face (11) and simultaneously aligning tabs (8A, B, C) in body (2).

Abstract: The device has a control unit (2) connected to the control (1) of the machine or installation, a main pump (3), an auxiliary pump (4) and two valves (5, 6), two pressure wave switches (7, 8) and a pneumatic line network (11, 12, 13). This line network (11, 12, 13) leads through the danger area to be monitored, in which safety sockets (9) are arranged. The device monitors itself by the main pump (3) continuously sending low pressure shocks through the line network which are passed on from the first pressure wave switch (7) to the second (8), are recorded by the latter and are evaluated by the control unit (2) as correct operation of the device. In the event of loading the danger area, which has a flooring (10), an overpressure shock occurs which is likewise transmitted via the pressure wave switches (7, 8) to the control unit (2) which in consequence shuts down the control (1) of the machine or installation. The device thus monitors not only the connected machine or installation, but also itself. Even a fault in one of its components (2-6, 8) leads to a shutdown after a minimum time. <IMAGE>
