A resistance E enables the electromotive force applied to the rectifier R to be adjusted so that it is within the range for which the instrument is accurate. A resistance B calibrated in degrees of temperature, is adjusted in accordance with the reading of a thermometer D in order to correct for temperature errors. A resistance C, calibrated in cycles per second, enables a compensation to be made for changes in frequency. Alternating current may be measured by including in the circuit a shunt resistance, across which the terminals T<1>, T<2> are connected.

Abstract: 423,071. Lubricating valves. AKTIEBOLAGET FILTRUM, 2, Norrmalmstorg, Stockholm. Feb. 23, 1934, No. 6008. Convention date, Feb. 23, 1933. [Class 12 (iii)] In a valve lubricator in which the lubricant therein is subjected continuously to the pressure of the fluid controlled by the valve, lubricant is fed to the sliding surfaces of the valve due to a pressure difference set up in the controlled fluid. In a valve for watersoftening apparatus the casing 2 has a duct 19 leading to a lubricator 12, and the rotatable valve body has ducts 20, 22 leading to the surface 3 to be lubricated. The lubricator 12 has a piston acted upon by the pressure water entering the valve through a pipe 5, the lubricator 12 and pipe 5 being interconnected by a pipe 18. The valve is shown in a position at which regeneration of the filter mass within the apparatus takes place. During this period a valve 11 is open so as to place a chamber 23 open to a drain pipe 9. Those valve passages 10 open to the chamber 23 are thus subjected to a low water pressure so that lubricant flows from the lubricator 12 to the surfaces 3 adjacent the passages 10. The invention may be applied to an automatically operated multiway valve of the type described in Specification 354,515, [Group XXIX]. In this modification the duct 19 leads to the space above the lubricator piston, and the space below the piston opens into the pipe 5. The lubricator 12 can thus be recharged with lubricant without detaching it.
