摘要： Apparatus for calibrating an ion analyzer comprises a calibration cell having defined therein a first volume for measuring an ion concentration of a sample when the instrument is operated in a monitoring and a second volume for measuring the ion concentration when the instrument is operated in a calibration mode. The first volume is included in, and forms part of, the second volume so that the matrix for the calibration measurement is essentially identical to that for the sample measurement. A double known-addition is used during the calibration mode to determine the calibration parameters.

摘要： A furniture worksurface unit for desks, tables, computer supports, etc. has a unique modular construction, comprising a top assembly with a skeleton-like top frame and a worksurface skin mounted on the upper side thereof. Leg frames are attached to the opposite ends of the top frame, and support the worksurface unit freestanding on a floor surface. Inner and outer leg covers enclose the leg frames, and underbelly covers are provided to enclose any exposed portions of the lower side of the top frame to facilitate manufacturing the worksurface unit in different widths from common parts, and provide aesthetic flexibility. Removable edges are mounted on the sides of the top frame, and are provided in assorted shapes and sizes to construct various top configurations.

摘要： A telephone line and instrument tester is disclosed which is operable by a consumer for determining whether a malfunction in a telephone system is caused by a malfunction in a telephone instrument of the system or by a malfunction in source related equipment of the system, such as a telephone line leading to a jack of the system. The tester is receivable in a modular telephone jack for testing the operation of source related equipment of the system and a modular plug of a telephone cord is receivable in the tester for testing the operation of a telephone instrument attached to the cord. A circuit in the tester is responsive to the flow of current therethrough for providing an indication of the operation of the source related equipment and/or the telephone instrument.
