  • Patent number: 6139297
    Abstract: In prior art designs, single-flight cast double worms with angles of contact > with large balance hollows at both ends and worm lengths of whole multiples of the pitch operate in the medium rotation speed ranges (.about.3000 min.sup..about.1) without imbalance. The desired use of special uncastable materials and the manufacturing complexity and the necessary dimensional stability even for extreme profile geometries pose additional problems in balancing which are solved by the present invention. Here, it is possible, by varying the angle of contact of the worm and any balance hollows and/or by altering the contour of the worms in the medium engagement region, to reduce the size of the balance hollows, sometimes to "zero", and with the possible use of additional masses. Besides the advantage of simple raw component manufacture, worms balanced in this way also permit the use of special materials and extreme worm geometries for fitting in pumps used in the chemical, medical and food sectors.

  • Patent number: 6137004
    Abstract: Described are preferred processes for recovering citric acid from a medium in which it is contained. The citric acid is recovered both effectively and in a form which is readily purifiable. In one preferred process, the citric acid-containing medium is contacted with a solid-phase free base resin having tertiary amine groups to adsorb the citric acid. The citric acid is then desorbed by displacement with a stronger acid, and a citric acid-containing fraction is collected substantially free from contamination by the stronger acid. In another preferred process, a citric acid-containing medium is contacted with a solid-phase divinylbenzene-crosslinked polymer having pyridine or aliphatic tertiary amine functions to adsorb citric acid, the contacting being at a temperature below about C. Adsorbed citric acid is then desorbed with hot H.sub.2 O at a temperature of at least about C.

  • Patent number: 6078873
    Abstract: A method and apparatus for real-time data stamping via datalink and volatile ECM timer/clock. An engine control module (ECM) includes a volatile time-keeping mechanism, such as time-keeping software code inserted into the ECM software, which is capable of keeping track of elapsed time as long as the ECM microprocessor is powered. The ECM initially sets the volatile time-keeping mechanism with real time (RT) at ECM power up by retrieving the current RT over an attached datalink from a non-volatile RT clock (i.e. a clock that keeps track of time even during ECM power down). Thereafter, the ECM microprocessor may time stamp stored data using RT from the volatile time-keeping mechanism. The present invention thus precludes the need to provide a dedicated RT clock for the ECM, or the need for the ECM to request RT over the datalink every time the ECM wishes to time stamp data to be stored.
