Abstract: A tornado protection system and related methods are provided. The tornado protection system includes a concrete pad. At least two anchors are affixed to the concrete pad. A vehicle is in a grounded position on the concrete pad. At least two anchor straps are connected between the vehicle and the at least two anchors, respectively, wherein the at least two anchor straps are connected to at least two sides of the vehicle, respectively. The tornado protection system may allow the vehicle to remain grounded throughout the duration of a tornado having a wind speed of at least 65 MPH, a horizontal wind force of at least 2,959 lbs., and a vector wind force of at least 4,638 lbs.

Abstract: The invention relates to a method for forming a green article for subsequent sintering or infiltration. This method includes providing a mold having an internal cavity that outlines the shape of the article, introducing metal or ceramic particles into the mold in an amount sufficient to provide the article in a desired size, adding a solution comprising an organic fluxing agent onto the particles with the solution carrying the organic fluxing agent into interstices between the particles, and freezing the solution to form a solid green article. The invention also relates to an apparatus and method for manufacturing dimensionally stable articles.

Abstract: A programmable controller having a processing unit, a screen, a control panel, and signal inputs and outputs, all of which are accommodated in a common housing. Switching functions can be programmed by the user via a menu-driven user interface on the screen. The status display is capable of being switched between an active and an inactive display status of the screen.

Abstract: A circuit configuration for a direct-voltage power pack of an electronically controlled switching device, particularly of a small programmable control system, which is externally supplied with voltage, having an arithmetic-logic unit, signal inputs and signal outputs. This circuit has a back-up supplier for the backup supply of the supply voltage and a detector for detecting the input voltage which is not backed up, the detector interacting with the arithmetic-logic unit in such a way that, in response to any voltage failure, the signal inputs are reliably prevented from being read in.

Abstract: The invention discloses a memory access control for coupled mask-program over microcontrollers in particular in connection with applications for memory storage programmable control in the low-cost region. The coupling of the microcontroller (MC1) and of the memory access authorization to the external program memory storage and data memory storage (7) is thereby based on a hardware wiring circuit in cooperation with a handshake provided by software. Always only one microcontroller accesses the external program memory storage/data memory storage (7) while the other microcontrollers access their internal program memory storage. The memory storage access is coordinated by the microcontroller (MC1) operating as a master through its output port (Px.y). On the hardware side the memory storage access signal (PSEN) and the address access signal (ALE) are multiplexed for the access-authorized microcontroller.
