The apparatus utilizes two stages of pressure regulation wherein the final stage is the demand regulator that delivers the breathing gas to the wearer. The first state includes a pair of pressure regulators connected in parallel with different outlet pressures, both of which reduce the pressure of the stored supply gas to pressures compatible with the second stage breathing demand regulator. A primary regulator in the first stage delivers a low output pressure to the second stage demand regulator.

A warning that the supply pressure has been depleted to a predetermined low level is also provided by a supply pressure actuated transfer valve which transfers the output of the first stage pressure regulators from the primary to the backup regulator thereby activating a whistle alarm device in the facemask to which the demand regulator is also mounted. The whistle is activated by the higher outlet pressure from the backup regulator during the inhalation phase of each breath in either of the two events of a "failure closed" condition of the primary regulator or the depletion of the supply pressure to a dangerously low level.

Multilevel cache system with graceful degradation capability

The directory and cache store of a multilevel set associative cache system are organized in levels of memory locations. Round robin replacement apparatus is used to identify in which one of the multilevels information is to be replaced. The directory includes parity detection apparatus for detecting errors in the addresses being written in the directory during a cache memory cycle of operation. Control apparatus combines such parity errors with signals indicative of directory hits to produce invalid hit detection signals. The control apparatus in response to the occurrence of a first invalid hit detection signal conditions the round robin apparatus as well as other portions of the cache system to limit cache operation to those sections whose levels are error free thereby gracefully degrading cache operation.

Tropomyosin-related kinase (Trk) inhibitors

Tropomyosin-related kinase inhibitors (Trk inhibitors) are small molecule compounds useful in the treatment of disease. Trk inhibitors can be used as pharmaceutical agents and in pharmaceutical compositions. Trk inhibitors are useful in the treatment of inflammatory diseases, autoimmune disease, defects of bone metabolism and/or cancer, and are particularly useful in the treatment of osteoarthritis (OA), pain, and pain associated with OA. Trk inhibitors are also useful for inhibiting tropomyosin-related kinase A (TrkA), tropomyosin-related kinase B (TrkB), tropomyosin-related kinase C (TrkC), and/or c-FMS (the cellular receptor for colony stimulating factor-1 (CSF-1)).

Gigabit Ethernet transceiver with analog front end

Circuitry to remove switches from signal paths in integrated circuit programmable gain attenuators. Programmable gain attenuators and programmable gain amplifiers commonly switch between signal levels using semi-conductor switches. Such switches may introduce non-linearities in the signal. By isolating the switches from the signal path linearity of the PGA can be improved.

Electric system

Electrolytic process using cation permeable barrier

Processes and systems for electrolytically processing a microfeature workpiece with a first processing fluid and an anode are described. Microfeature workpieces are electrolytically processed using a first processing fluid, an anode, a second processing fluid, and a cation permeable barrier layer. The cation permeable barrier layer separates the first processing fluid from the second processing fluid while allowing certain cationic species to transfer between the two fluids. The described processes produce deposits over repeated plating cycles that exhibit deposit properties (e.g., resistivity) within desired ranges.

Apparatus and method for power dissipation reduction in a communication system

A method for reducing power dissipation within a communications system having a plurality of adaptive filters with a plurality of taps, each tap switchable between an active and an inactive state and each having a coefficient. The method involves specifying an acceptable error for the system, and setting a tap threshold for each active tap. For each active tap, those taps having a coefficient with an absolute value less than the tap threshold set for the active tap are deactivated. A system error is computed and compared to the acceptable system error. If the computed system error is less than the acceptable system error, the tap threshold for each active tap is increased. The above process is repeated until the computed system error approaches the acceptable system error without exceeding the acceptable system error.

Die manipulator

An apparatus for manipulating the upper and lower dies of a die set comprising a gantry having a fixture mounted on a main frame for up and down movement, and a sub-frame mounted on the fixture for 180° of rotation. Clamping units are mounted on the sub-frame for clamping the upper die to the sub-frame when the fixture is in a lower position at a work-transfer station. The die set is transported on a cart to the work-transfer station where the upper die is clamped to the sub-frame. The fixture is raised to elevate the upper die to an upper position. The cart is moved away from the work-transfer station carrying only the lower die with it. The upper die is inverted, lowered onto a second cart and it, too, is then moved away from the work-transfer station. Both dies now face upwardly for convenient inspection, cleaning and/or repair. The transporter cart table on which the die set is supported can be rotated to any desired angle such as 90°, so that after the upper die has been removed, the lower die may be turned to a position suitable for inspection, cleaning and/or repair.

Method and apparatus for thickness control of a coating

An improved air knife apparatus and method for controlling coating thickness on a moving metal strip. Air flow from blowers is supplied through a plenum chamber common to an air knife and a diffuser spaced along the path of strip travel. A valve between the plenum chamber and diffuser controls the relative flow of air through the knife and diffuser to establish the desired pressure and flow at the air knife to modify the thickness of the coating on the strip. The flow through the diffuser is directed against the strip at a location subsequent to the knife in the direction of strip travel, to chill the coating.

Self-unloading magnetic coupler

In a magnetic coupler, a pair of magnet rotors is slidably mounted on rods. Ferrous material on the conductor rotors attracts the permanent magnets in t he magnet rotors. Under static or relative static conditions, the attractive force urges the magnet rotors toward the conductor rotors to create a minimu m, operational air gap therebetween. When there is a significant relative rotational velocity between the magnet rotors and the conductor rotors, a repulsion force urges the rotors apart. During start-up, latch arms retain t he magnet rotors apart from the conductor rotors by a larger, soft-start air ga p. During operation, centrifugal force moves the latch arms out of their active position. If the rotational speed of the load shaft decreases rapidly during operation, the magnet rotors move apart from the conductor rotors by a still larger, fully disengaged air gap.
