Abstract: An automatic dialer which receives address digits dialed from a telephone set and outdials a destination number. A programmable Send Only M.O.S. Memory stores a plurality of destination numbers at address locations. The dialer can be connected to a telephone line at the central office, at the subscriber's location, or anywhere on the line, to a PBX trunk, either at the PBX or the control office. The dialer can be made transparent to dialed digits upon receipt of a predetermined digit.
Abstract: A fluid conductivity measurement apparatus in which the minimum conductivity of one fluid of a group of fluids is determined by comparing electrical conductivities, and the ratios of each of the conductivities to the minimum conductivity are calculated. Where cow's milk is the fluid passing through the apparatus, a determined deviant increase in ratio has been found to be evidence of a high probability of bovine mastitis.
