Abstract

844,010. Regulating liquid levels. MOELLER, C. Aug. 5, 1958. No. 25081/58. Class 123(1) [Also in Group VIII]. A liquid level regulator, e.g. for a washing machine 1, comprises a U-gauge in the form of a block 10 of thermoplastic material with a vertical channel 9 the lower end of which communicates, through a restriction 13, with a transverse channel 12 opening into the lower ends of vertical channels 14-17 having adjustable contact rods 18-21 respectively. The upper ends of the channel 9 and a vertical tube 4 are interconnected by a narrow tube 8, and the lower ends of the tube 4 and the machine communicate with each other through a tube 3. A vertically adjustable tube 7 screwed into an opening in the top 6 of the tube 4 ensures, when the machine is empty, that the tube 9 is open to the atmosphere through the tubes 8, 4, 7. During filling, water rises in the tube 4 and, upon reaching the level of the lower end of the tube 7, prevents the escape of air from the latter, the liquid, e.g. mercury 22, in the tube 9 being proportionally compressed and that in the tubes 14-17 rising correspondingly to engage one or more of the contact rods 18-21. Electrical circuits are completed between the rods 18-21 and a wire 25, extending through a plug 11 which closes one end of the channel 12, to control e.g. the liquid level of the container and to initiate washing operations or timing mechanism.
