  • Publication number: 20180291497
    Abstract: A method of manufacturing indium tin oxide includes sputtering indium and tin from a target onto a substrate, the sputtering including moving the target along a path over the substrate. The indium tin oxide may have a sheet resistance less than 0.5 ?/?. An indium film includes: a first moving target sputtered indium tin oxide layer; a second moving target sputtered indium tin oxide layer on the first moving target sputtered indium tin oxide layer; and a third moving target sputtered indium tin oxide layer on the second moving target sputtered indium tin oxide layer. A transparency includes the indium tin oxide, and a flying vehicle includes the transparency.

  • Patent number: 6019867
    Abstract: Mixed glycols, as exist in the waste stream from a glycol production unit, are utilized for production of a liquid resole resin in an aqueous alcoholic solvent. The solvated resole resin is employed as a binder for production of laminates.

  • Patent number: 4686701
    Abstract: A distributed control switching system where the system control units cooperatively perform the terminating port determination function. The control unit associated with the terminating port stores sequence call data defining whether calls are to be completed to that terminating port or are to be forwarded to another directory number. Upon determining that a given call is a sequence call, the control unit associated with the original terminating port determines the terminating port defined by the second directory number and effects a reduction of the sequence call to a simple call between the originating port and the second terminating port. This is done either by transmitting a control message defining the originating and terminating ports to the control unit associated with the second terminating port or by returning the setup sequence to the control unit associated with the originating port which then frees any switching system resources previously allocated to the call and transmits the control message.

  • Patent number: 4644528
    Abstract: A distributed control switching system where the system control units cooperatively perform the terminating port determination function. The partial results obtained when a first control unit is unable to fully determine the terminating port are advantageously used by the second and subsequent control units such that time-consuming database access tasks are not unnecessarily repeated.
