Abstract: A dynamic content addressable memory (CAM) cell is disclosed which is suitable for constructing relatively high-speed and large-capacity CAM arrays, having binary and ternary storage capability. The cell comprises a pair of storage devices, comparing means and a pair of memory access devices. In a compare operation, the comparing means couples a match line to a discharge line during a mismatch between a pair of complementary search bits carried on a pair of search lines and a pair of complementary data bits stored in the memory. In a read or write operation, the pair of access devices are activated by a word line to couple the storage capacitors to a pair of bit lines. A '0' or a '1' data bit is stored when the two storage capacitors carry complementary charges. A 'don't care' state is stored when both capacitors are discharged.

Title: Method for testing the stability of vertically braced masts
Inventor: ROCH MATHIAS
IPC: G01M5/00
Filed: 1998-01-09
Granted: 2005-05-10
Abstract: The invention relates to a method for testing the stability of vertically braced masts wherein the relevant mast is subjected to the load of a bending force starting from a defined initial value, and increasing to, at most, a maximum pre-set testing force above its bracing, said mast thereby being laterally displaced. Subsequently, on termination of the load test procedure, said load is removed from the mast, whereby it is subjected to a restoring force which reduces to zero. Possible remaining lateral displacement of the mast as the restoring force returns to zero is determined and evaluated in conjunction with the load removal procedure to determine damage to the mast and/or its bracing. In order to further determine the type of damage to the mast, the mast is subjected to an additional bending force in the opposite direction of the first bending force, and then the load is once again removed from the mast in a second test procedure. In this case a possible remaining displacement of the mast/bracing system must be determined.      The determined remaining displacements are evaluated in conjunction with the highest mast loads to determine the type of possible damage to the mast.

Abstract: A tire pressure and temperature measurement system adapts a Y-block (30) to an existing valve stem (20). One branch (44) of the Y-block accepts a conventional valve core (42) and another branch (38) accepts a flexible tubular temperature sensor (36) that leads "down the throat" of the existing valve stem and into the interior of a tire (14, 18). A second embodiment is adapted for use on inside dual tires (18).  Making a measurement entails attaching a pressure sensor (40) to the valve stem and attaching a hand-held processor (112) to the sensors. The hand-held processor reads the current tire pressure and temperature; executes a program (Eqs. 1-6) that accounts for measured and target temperatures, vapor pressures, and gas compressibility; and indicates how much pressure to add or subtract to the tire to achieve an accurate final tire operating pressure. In third and fourth embodiments, respective spherical (70) and U-shaped channel (120) protective housings enclosing pressure and temperature sensors (72), a controller 76, and a data transceiver (74) are loosely placed or attached by magnets (122) within the interior of a tire (126). A remote measurement system (80) receives at another data transceiver (108) pressure and temperature data transmitted from inside the tire while the vehicle is moving and conveys the data to a processor (112) for executing the above-described program.

Abstract: A loosely coupled rotary transformer (100) includes a resonant circuit, such as a resonating capacitor (C3) connected to a power MOS transistor (Q3), coupled across the primary coil (102) of the transformer (100). The resonant circuit is connected and disconnected from the transformer (100) during a power transfer mode and a data transfer mode, respectively. During the power transfer mode, stored energy in the leakage inductance of the primary coil (102) is used for power coupling, via the resonant circuit (C3, Q3), instead of being dissipated as heat. The resonant circuit (C3, Q3) is disconnected from the rotary transformer (100) during the data transfer mode to maximize bandwidth for two-way data transfer between the primary and secondary sides of the transformer (100). Including the resonant circuit (C3, Q3) in the loosely coupled transformer (100) ptimizes data and power transfer without requiring the use of high-cost, high-efficiency magnetic structures in the core of the transformer (100).

Abstract: The invention relates to free-flowing castable and castings produced therefrom. Refractory nonbasic and basic castables have been known for a long time. The traditional refractory castables have thixotropic properties and must be lined using vibration technology. In the past, free-flowing castables were solely based on alumina raw materials. Attempts to produce an aqueous, highly concentrated basic suspension which would form the basis of free-flowing castables failed to meet the requirements in terms of rheological properties and a low degree of hydration of the MgO-based materials. It is the aim of the invention to provide the above-mentioned castable for the monolithic lining or repair of high-temperature equipment and for the production of refractory castings. This is achieved by providing a fine-grained and a mixed fine and coarse-grained alternative. For the fine-grained alternative a refractory, dilatancy-promoting material on MgO  basis with a grain size between 0.1 and 45 µm and at least one dilatancy-promoting dispersing and wetting agent is employed with the addition of predetermined amounts of mixing water. For the mixed fine and coarse-grained alternative, again on MgO basis, in addition a refractory material with a grain size of up to 15 mm as well as binding agents are employed. In both alternatives, refractory and other additives improving the quality of the final products can also be employed.
