Abstract: Abstract A memory may contain a large number of bytes of data perhaps as many as 256 megabytes in a typical large memory structure.  An error correcting code algorithm may be used to identify failing memory modules in a memory system.  In a particular embodiment, a number of spares may be provided on each  memory  card  allowing  a  predetermined  number  of defective array modules to be replaced in a storage word. With double bit correction provided by the error correcting code logic, a number of bits can be corrected on a card or a larger number of bits can be corrected on a card pair, where the larger number of bits is somewhat less than double the number of bits which can be corrected on a single card.  The address test in accordance with the present invention then produces a pattern that will create a difference greater than that larger number of bits between the data stored in a storage location under test and any address that could be accessed by an address line failure.  The method according to the present invention predicts the effect of an address line failure external to the array modules and internal to a card pair and then tests to see if a failure has occurred. The address test does not declare an address failure until a predetermined number of bit failures on a card is found. The test is valid  for  single  and multiple  address  line failures.  Since only one address bit is changed for each path through the test other failing address lines will not be detected until the path with those failing address bits are tested. Thus, even with multiple address line failure the two addresses that are stored to and fetched from are the only one address bit apart.

The  cartridge  has top (32), bottom  (34),  sides (36,  38),  front (40) and rear (42) surfaces  and  in-cludes a printhead (44) on the bottom surface, an elec-trical contact strip (46) on the back surface connected to  the  printhead, referencing pads (56) on  the  side surfaces,  and a lip (64) on the back surface  for  ac-cepting the snap-spring.     Referencing surfaces (60) are provided for receiv-ing the referencing pads on the cartridge.  The  spring pad urges the interconnect strip against the electrical contact of the cartridge.     The  printhead cartridge/carriage assembly of  the invention  requires  only one hand of the  operator  to both  insert and lock the cartridge in position.   Fur-ther,  the cartridge/carriage assembly provides  simul-taneous  alignment of the printhead in the X, Y, and  Z directions.  Finally, contact between the printhead and the  interconnect strip is reliably made each time  the cartridge  is inserted and locked in position,  thereby ensuring proper nozzle firing each time.

Granted: 1994-09-20
Abstract: ABSTRACT OF THE DISCLOSURE             A two-stage process for purifying wastewater containing organic and adsorbable pollutants includes the steps of first aerating the wastewater in the presence of a powdered adsorbent, such as activated carbon, and biologically active solids in the aeration zone of a primary treatment zone which also includes a quiescent zone.  The thus-treated water passes from the aeration zone to the quiescent zone where it is retained a sufficient time for a substantial portion of the suspended solids to settle by gravity.  The partially-treated wastewater overflowing from the quiescent zone is introduced into one or more contact zones wherein it is agitated, preferably by aeration, in the presence of a powdered adsorbent, agitation is terminated and the solids are allowed to settle by gravity and, after completion of settling, clarified, substantially solids-free water is withdrawn from each contact zone.

Abstract: Abstract An extruder for treating high-oil-content material such as certain oilseeds, is used to prepare the material for later solvent extraction of oil from the material.  The extruder has an elongate barrel and a rotating wormshaft therein which advances the material from an inlet hopper to a discharge die plate having at least one restricted orifice.  As the material advances through a series of compaction worms, it is worked and compressed.  Steam may be injected to raise the temperature and moisture content of the material.  The pressure on the material is increased and is maintained sufficiently high so as to prevent any water content from vaporizing even if its vapor pressure significantly exceeds atmospheric pressure.  The barrel wall includes a perforate or slotted section downstream from a solid wall section, and pre-ferably immediately before or close to the discharge die plate.        This allows any oil which is liberated from the oil-bearing material being worked to drain out of the extruder, thus making it feasible to process high-oil-content materials in the extruder without the prior use of a screw press.  The material exiting the die plate into atmospheric pressure expands because of vapori-zation of the moisture content, yielding a porous material very suitable for solvent extraction.  The feed worm design provides for greatly increased throughput of material from the feed hopper to the compaction worm.

Abstract: ABSTRACT           An atomizer wherein a housing is threadedly connected with an air-supplying first nozzle which surrounds and centers a water-supplying second nozzle. The second nozzle extends beyond an annular orifice of a channel which discharges two streams of air, one in the form of a swirling annulus and the other in the form of a substantially straight stream with the annulus.  The two air streams atomize the flow of water which issues from the second nozzle in such a way that the resulting atomized flow contains minute droplets of water all the way across its cross-sectional area.  An annular swirling member is installed between the two nozzles to form the first air stream.  The two nozzles have abutting surfaces provided on two sections one of which surrounds the other to center the second nozzle in the first nozzle and vice versa.
