  • Patent number: 4772377
    Abstract: A membrane anchor for an ion-selective electrode may be formed by intersolubilizing an ion-selective membrane lying above a sensing pad with a region of thermoplastic material laterally disposed around the membrane. A first layer of electrically insulating thermoset material lies beneath the thermoplastic material and in intimate contact with an electrically insulating substrate. A second layer of exposed thermoset material lies above the thermoplastic material and contacts the first layer of thermoset material around the entire lateral perimeter of the thermoset material.The membrane anchor may be usefully employed with an ion-selective electrode having an electrically insulating substrate with a substantially planar surface and having non-metallic means for sensing a potential affixed to the surface beneath an ion-sensitive membrane.

  • Patent number: 4771429
    Abstract: A circuit is disclosed which combines the functions of a cyclic redundancy check code (CRCC) generator and a pseudo-random number generator in such a way that common elements are shared rather than duplicated. A 16-stage shift register and two linear feedback paths are included for the CRCC and pseudo-random number generators. A control section of the circuit controls the mode of operation of the circuit according to the state of a mode control signal. A signal on a clear line resets the shift register or initializes it with a selected value depending on the state of the mode control signal. The mode control signal also controls the input of data on a data line and the output of generated CRC and pseudo-random access codes on output lines.

  • Patent number: 4765843
    Abstract: A process for preventing contamination of a reagent system by a reagent delivery system. The process is suitable for performing an iron determination of a sample which prevents iron contamination of the sample from metal or iron-containing surfaces contained within the apparatus used to perform the iron assay. The process comprises pretreatment of the reagent delivery system surfaces with a silane solution and then washing the pretreated surfaces with water to remove any excess silane solution. Generally, the silane solution is an organosilane solution which can be an emulsion.
