  • Patent number: 5152270
    Abstract: An engine control system for an internal combustion engine is equipped with dual air-fuel ratio feedback control systems for feedback controlling air-fuel ratios for two groups of injectors. The system includes a common air flow rate sensor, common to both groups, for detecting a common air flow rate introduced into the cylinders and an individual air-fuel ratio sensor for each group of injectors for determining an air-fuel ratio related value for its respective air-fuel ratio feedback control system. A feedback correction value for correction of fuel injection is determined from the air-fuel ratio ralated values for each air-fuel ratio feedback control system. An air flow rate is corrected based on the feedback correction values for correction of fuel injection for the dual air-fuel ratio feedback control systems. Virtual fuel injection rates for the two groups of injectors are then determined from the corrected air flow rate.

  • Patent number: 5153562
    Abstract: A method of deactivating electromagnetic detection labels comprising a resonant circuit, in which an interrogation field is generated, the frequency of which is varied through a frequency range comprising the resonant frequency of the resonant circuit of the detection label, and in which a label is deactivated with an amplified interrogation field. According to the invention, the frequency of the interrogation field is continuously and periodically varied between a first and a second frequency; upon detection of a detection label, the resonant frequency of the label is detected, and at at least one of the subsequent times the periodically varying frequency passes the detected frequency, the field intensity at the location of the detection label is greatly increased for a short period of time.

  • Patent number: 5150843
    Abstract: Apparatus for processing solid waste includes a chamber for receiving the waste, which may be any contaminated or non-contaminated waste including paper, plastics, cloth, metal and hospital sharps, and a ram for forcing the waste, to which germicide may be added, into contact with a plurality of cutting heads. The cutting heads which shred, shear and cut the waste are each mounted on an elongated rotating shaft. Each cutting head includes a plurality of parallel cutting blades separated by spacers. Adjacent cutting heads mesh together so that cutting blades of one cutting head interdigitate with spacers of an adjacent cutting head. A pair of curved doors close the chamber closely adjacent the cutting heads while the waste is being cut, and are opened for releasing the cut waste. The doors include elongated parallel grooves alternately for receiving the cutting edges of the cutting blades and for receiving the spacers.

  • Patent number: 5151617
    Abstract: A superconducting logic circuit is configured by using two kinds of input-output type quantum flux parametrons (QFP), that is, a periodically excited input-output type QFP and an arbitrarily excited input-output type QFP. The periodically excited QFP is excited by periodically varying exciting magnetic flux to amplify a binary magnetic flux. The arbitrarily excited QFP is excited by magnetic flux output signals of upstream QFPs.

  • Patent number: 5151933
    Abstract: A key telephone system with a re-dialing feature has a memory with two memory areas. One of the two memory areas is provided for an outside-line call, and the other is provided for an internal-line call to a particular extension. Each memory area memorizes a dialed number therein and replaces a number of the last intended call, previously present in the memory area, with the most recently dialed number. A re-dialing push-button automatically retrieves the number of a last intended outside-line call, memorized in the outside-line memory area, when actuated following a selection of an outside-line call, or the number of a last intended inside-line call to a particular extension, memorized in the extension memory area, when actuated following a selection of an internal-line call to a particular extension.

  • Patent number: 5149515
    Abstract: During the pickling, etching, chemical shaping etc. of steels, stainless steels, special alloys and special metals and the dissolution of those metals, metalliferous solutions of the acids employed arise in the course of such processes which must either be disposed of by neutralization or be used for the recovery of the acids and metals by expensive processes. According to the invention the production or recovery of nitric acid or a mixture of nitric acid and hydrofluoric acid takes place by spray-roasting the solutions at temperatures of 200.degree. to 500.degree. in a reactor (1) and subsequent absorptions or condensation of the gases generated in column means (7, 8) at temperatures of 0.degree. to 70.degree.

  • Patent number: 5149558
    Abstract: A process whereby sweetened condensed milk (SCM) or sweetened condensed skimmed milk (SCSM) is used as a starting material. The SCM or SCSM is pumped to a stainless steel refrigerated holding tank where it is diluted to 50.degree.-65.degree. brix (solids) with water. The product is then pumped into a continuous vacuum dryer, through a deaerator to control foaming and then into a feed pan. A stainless steel feed roll rotates in the feed pan and pick up SCM or SCSM product which then deposits a uniform layer of the SCM or SCSM on a continuous stainless steel belt. The clearance between the feed roll and the stainless steel belt is 0.015 to 0.025 inches. The SCM or SCSM product then goes through three heat zones at which vapor is driven off. Heat zone 1 preconcentrates and degasses the SCM or SCSM. This increases the area and volume of product so that it can withstand rapid evaporation occurring in heat zone 2. Heat zone 2 includes a hot drum at which a major portion of the drying occurs.
