摘要:
The present invention relates to the field of defoaming equipment, and more particularly, to removing, defoaming, and storing large amounts of foam after a Blast Mitigation or Decontamination Foam has been used in either an open area or in an contained area. The invention provides an apparatus for defoaming, comprising: a vacuum system for collecting foam, the vacuum system including a vacuum head for drawing the foam through a suction hose terminating in a nozzle, the vacuum system feeding the foam into a holding tank; the holding tank initially storing a quantity of defoaming agent; and a pump for drawing the defoaming agent from the holding tank and feeding the defoaming agent to at least one injector, the at least one injector being fitted on the vacuum-side of the vacuum system, whereby the defoaming agent is actively mixed with the collected foam, reducing the collected foam, and the reduced foam and defoaming agent are recirculated through the pump; the nozzle, the suction hose, the vacuum system, the at least one injector and the holding tank being of chemical-resistant construction.

A system for generating one or more common address signals for multi-port memory arrays. The system includes circuitry receiving one or more read address signal; circuitry receiving one or more write address signal; circuitry receiving an array clock signal; circuitry receiving one or more enable signal; and circuitry generating the common address signals in response to the enable signal, the array clock signal and one of the read address signal and write address signal.

A method and circuit for implementing array bypass operations without access penalty for a random access memory circuit. The random access memory circuit includes a circuit array of memory cells, a read circuit, a data output register, a data input register, a write circuit, a write control register, a bypass control register, a row decoder, and an address register. The method includes directly coupling the read circuit to the data output register and coupling-the bypass control register to the row detector. The bypass control register issues a bypass signal to the row decoder. The bypass signal includes one of an active bypass signal and an inactive bypass signal. If the bypass signal issued is inactive, then one of a read operation and a write-through operation without bypass is performed. If the bypass control signal issued is active, then a write-through operation is performed in bypass mode.

An arbor system includes an arbor, a clamp body of a power tool, a tightening feature and an optional snap feature. The arbor has a flanging feature, a thread and a number of circumferentially arranged driving pins. The clamp body is sandwiched between the arbor and tightening feature in a pressed contact with the flanging feature defining a releasable fix that is fully form fitting. Operational tilt and load torque are transmitted without affecting the tight-screwed interlocking between thread and tightening feature. A snap feature, in the form of a spring pin or a spring tongue of a sandwiched washer, may secure the tightening feature against inadvertent unscrewing. The snap feature and snap serrations may be configured as a ratchet such that the snap feature needs only be actuated during unscrewing of the tightening feature.

A thin-plate microchannel structure of channel depth of 500 microns or less and capable of withstanding pressure up to 6,000 psi inch is disclosed. The thin-plate microchannel structure may be formed from metal, ceramic or polymeric materials. It can be employed to facilitate the exchange of heat between a single fluid in liquid, gaseous or supercritical state and another device, such as an integrated circuit, with which it is near or in contact.

A cooling cycle is disclosed employing carbon dioxide in a supercritical state throughout the cycle. Heat absorption depends solely on the heat capacity of the fluid as it flows through the hot zone. Consequently, there is no change of state, as would be the case in evaporative heat absorption. The supercritical carbon dioxide is maintained above the dew point that could be expected for devices operating indoors or outdoors.

A pacifier includes a nipple, a shield and a handle. The nipple comprises a pair of wings extending longitudinally along a bulbous end of the nipple. The wings allow for air to exit and enter the space between the palate and the nipple to prevent a vacuum therebetween. Alternatively, the nipple has a channel system comprising a series of holes on the surface of the nipple, some contacting the palate, to also allow the air to enter and exit the space between the palate and the nipple. The stem of the nipple may also have a transverse hole which receives the baby teeth to prevent an open bite.

The method described uses a Skip-Over technique which requires a set of muxes at the input and output of a block that is to be repaired. The improved method of implementing I/O redundancy control logic has a minimal impact to both chip area and chip wire tracks. To overcome problems of required real estate usage on a chip that was undesirable enables use of odd and even decoder outputs that can share a single wire track, the same wire being utilizable for both odd and even decoder outputs. In order to implement the decode and carry function as a centralized function, there arises a requirement that logically adjacent decode circuits (decoders connected by a carry signal) should be physically close together to minimize the overhead of the carry wiring. If the decode structure and the mux structure are arranged orthogonal to each other, then each decoder output would require a wire track. The described method however, allows odd and even decoder outputs to share the same wire track. This reduces the number of wire tracks from 1 track per I/O to 1 track per 2 I/Os.

An access valve suitable for controlling fluid flow into and out of a chromatography column has a central axially movable probe with a head acting as a spool valve in a barrel. Axial movement of the probe adjusts the valve between a fully open condition, in which both a first conduit extending through the probe and a second conduit defined around the probe are open to the column interior, a partly open condition in which a second sealing land on the probe closes the second conduit, and a fully closed position in which both conduits are closed. The three positions are useful for packing and unpacking chromatography media into and from the column. In the closed condition of the valve, the first and second conduits communicate with one another so that the valve interior can be cleaned while the column is operating.
