Abstract: An arc spinner interrupter includes a first fixed electrical contact and a ring electrode coupled to the fixed contact through a field coil surrounding the ring electrode. A second electrical contact has an arm which moves along a path perpendicular to the central longitudinal axis for selective connection with the fixed contact. The arm may have a generally L-shaped configur­ation including an angled portion that extends in a direction parallel to the central longitudinal axis and a conductor extends toward the angled portion through the ring electrode along the central longitudinal axis. The conductor has an inner axial end that is spaced slightly from the angled portion of the arm when the arm is moved to a position intersecting the central longitudinal axis so that a grading function is carried out on the electro­static field surrounding the angled portion of the arm. This grading function serves to limit the stress exerted by the electrostatic field adjacent the angled portion of the arm section. Further, the presence of the conductor within the ring electrode reduces the wear to the angled portion by permitting transfer of an arc from the angled portion during an interruption operation such that heat from the arc is distributed in the conductor rather than in the angled portion. During movement of the second contact away from the fixed contact, electromagnetic forces are simultaneously exerted on the arc due to the general L-shape of the arm of the second contact and move the arc material both toward the ring electrode and in the direction in which the arc spins once it has commuted to the ring electrode.

Abstract: Apparatus (11 or 41) for allowing low noise and fast frequency switching of a ferri-resonant oscillator, such as YIG, that uses a coil (13, 42) to control output signal frequency by current level. The apparatus positions an active filter (27) in parallel with the oscillator coil (13, 42), which can be set to one of two impedance levels. A low impedance level provides low pass filtering of the current to the oscillator coil for low noise operation. A second high impedance level allows fast settling of transients during frequency changes. Once current levels have stabilized, the active filter (27) can then be switched to low impedance mode without creating a significant transient. This facilitates fast frequency switching.

Abstract: An anti-oxidation agent for preventing oxidation of a stainless steel strip during continuous annealing comprising a colloidal inorganic substance which can be crystallized at a temperature not higher than 1300°C at least one compound having a melting point not higher than 1300°C, selected from the group consisting of silicates, borates and phosphates, a dispersion agent, and the balance substantially water. The anti-oxidation agent is applied to the surface of the stainless steel strip. During the annealing, the anti-oxidation agent enhances the heat absorption so that the stainless steel strip temperature is elevated to the annealing temperature in a short time. The anti-oxidation agent on the strip surface forms a film of a fine structure which keeps the strip surface away from oxidizing components of the annealing atmosphere so as to suppress generation of oxide scale. The film is easily separated due to thermal contraction in the course of the cooling after the annealing.

Abstract: Ti powders and Aℓ powders are combined to prepare a mixture of 40 ∼ 55 at% of Aℓ and the balance of Ti. After CIP and degassing, plastic working by hot extrusion is applied to form a shaped mixture of Ti and Aℓ The shape is then processed by HIP to synthesize titanium aluminide while diffusing Aℓ into the Ti structure to form an Aℓ₂O₃ phase occurring from both the reaction between Aℓ and oxygen contained in the Ti structure and the oxides on the Aℓ surface, and to disperse the Aℓ₂O₃ to form the Aℓ₂O₃ protective film. With the reaction between Aℓ and oxygen contained in the Ti structure and with the "Pegging" effect, both the Aℓ₂O₃ phase formed at the grain boundaries of crystals or in the crystal grains of titanium aluminide and the Aℓ₂O₃ phase existing on the surface of raw material Aℓ powder peg the surface Aℓ₂O₃ film to the surface of the titanium aluminide body. This "Pegging" effect enhances the adhesiveness of the film and improves the oxidation resistance of titanium aluminide.

Abstract: The invention achieves the object of developing a read/write circuit for static RAMs which accomplishes both a high reading rate and at the same time a great immunity to faults in the reading cycles. Use is made of a read/write circuit for a static RAM having n bit line pairs (BLi;/BLi; where i- phi ...n) and m word lines (WL phi ...WLm), in which circuit the bit line pairs (BLi;/BLi) are in each case connected to the nodes (Ki;/Ki) of sensor flip-flops (5.i), the base transistors (8.i) of which are controlled by an associated latch clock (LTk). The nodes (Ki;/Ki) are connected via selection transistors (9.i;9.i') to data line pairs (DLk;/DLk) of the RAM. The selection transistors (9.i;9.i') are driven by outputs (BDi) of a column decoder (3) which are assigned to the individual bit line pairs (BLi;/BLi). According to the invention, there is arranged in each case between true bit line (BLi) and negated bit line (/BLi) of each bit line pair (BLi;/BLi) and between true node (Ki) and negated node (/Ki) of the associated sensor flip-flop (5.i) a connection (4.i) which can be controlled in its conductivity, allowing passage when writing to the RAM as well as being conductive when reading at the beginning of the associated latch clock (LTk) and losing its conductivity in proportion to the rate at which the potential of the latch clock (LTk) rises. The invention is used in static RAMs for further speeding up data access during reading. <IMAGE>
