Air translating apparatus

Abstract: This invention relates to an electric fan, and particularly to an electric fan adapted to be mounted on a substantially vertical support, such as a wall, or supported upon a substantially horizontal surface, such as a desk. An object is to provide improved apparatus of the character set forth....

Current limiting circuit interrupter with improved operating mechanism

Abstract: A current limiting circuit interrupter includes two parallel pivoting contact arms carrying contacts at the ends thereof. The upper contact arm is pivoted upon a carriage which is in turn pivotally mounted upon a mechanism frame. A latch rod is movably secured in arcuate slots in the sides of the mechanism frame. When the circuit interrupter is in the closed circuit position, a pair of springs connected between the latch rod and the carriage urges the latch rod against a reaction surface of the upper contact arm to provide contact closing pressure. Upon occurrence of severe overload current conditions, the upper contact arm pivots upon the carriage, moving the latch rod within the arcuate slots to release the contact closing pressure, allowing the springs to move the latch rod against a latching surface of the upper contact arm to latch the upper contact arm in the open circuit position.

Gas turbine vane with enhanced cooling

Abstract: A gas turbine stationary vane having an airfoil portion and inner (36) and outer (38) shrouds. Five serpentine radially extending cooling air passages (51-55) are formed in the vane airfoil. The first passage (51) is disposed adjacent the leading edge (40) of the airfoil and the second passage is disposed adjacent the trailing edge. A first portion (80) of the cooling air enters the first passage (51), from which it flows sequentially to the second, third, fourth and fifth passages. Additional cooling air (83) enters the third passage directly, thereby bypassing the first and second passages and preventing over heating of the cooling air by the time it reaches the fifth passage. A radial tube (45) extends through the second passage and directs cooling air through the airfoil, with essentially no rise in temperature, to an interstage cavity (70) for disc (42, 43) cooling. Fins project (60-64) into each of the passages and serve to increase the effectiveness and flow rate of the cooling air. The fins in the first and fifth passages are angled so as to direct the cooling air toward the leading (40) and trailing (41) edges, respectively. In addition, the fins in the second through fifth passages are angled to retard flow separation as the cooling air turns 180° from one passage to the next.

EBT: A Comprehensive Test Generation Technique for Highly Sequential Circuits

Abstract: A new test generation technique for highly sequential circuits, utilizing functional models, with ability to produce tests for specific faults while avoiding races, is presented.
