  • Patent number: 4130395
    Abstract: The extent of lysis or red blood cells treated with a test solution containing a known or suspected agglutinating factor, and preferably with a lipid, serves for blood typing and cross matching, and, in addition for the detection and semi-quantitation of tumor factors and of viruses including myxoviruses (influenza, mumps) and adenoviruses (herpes), and of antibodies to such viruses. The method involves as one step the agglutination of erythrocytes (RBC) as well as lysis. Consequently, it is useful for detecting agglutinating factors. An apparatus for carrying out the method automatically is described.

  • Patent number: 4130164
    Abstract: The efficiency of conversion of coal in the coal-gasification process is increased by pre-treatment of the coal to increase the fluid-permeability thereof. The reagent used for increasing the coal permeability is recoverable in high yield. Pre-treatment of bituminous coal by this process makes it possible to gasify coals of this rank effectively, such coals previously having been gasifiable only at low conversion efficiencies. Pre-treatment with a permeability-enhancing reagent is also useful as a step in the process of dissolving coal.

  • Patent number: 4128798
    Abstract: A charging circuit for charging a DC cell is provided. A supply circuit produces a charging current at a first selected value and a current gating circuit is disposed intermediate the DC cell and the supply circuit for selectively applying the charging current produced by the supply circuit to the DC cell. A control circuit is coupled to the DC cell and to the gating circuit, the control circuit being adapted to detect when the cell is charged to a predetermined maximum voltage, and in response thereto control the gating circuit to prevent the charging current from being supplied to the DC cell. The control circuit is further adapted in response to a drop in the voltage of the cell to a second predetermined level, to control the gating circuit and thereby permit a charging current of a second value reduced with respect to said first value to be applied to the DC cell.

  • Patent number: 4122661
    Abstract: An electronic timepiece having detecting and control circuitry for preventing a digital display from being driven by a DC energizing signal is provided. The detecting and controlling circuitry is coupled intermediate the decoder circuitry and driving circuitry in an electronic timepiece digital display arrangement and detects the presence or absence of an intermediate frequency signal being produced by the timekeeping circuitry and applied to the driver circuitry to effect AC driving of the digital display. In response to detecting the absence of an intermediate frequency signal applied to the driver circuitry, the detecting and controlling circuit prevents the decoder circuitry from applying to the driver circuitry decoded timekeeping signals for effecting driving of the digital display, and thereby prevents inadvertent DC driving of the digital display.
