Abstract

385,002. Temperature alarms. McINTOSH, D., 17, Gill Bridge Avenue, Sunderland. Feb. 12, 1932, No. 14140/31. [Class 47 (i).] In a temperature alarm of the mercury-tube type, the upper contact wire 6 is slidable through the upper end of the tube 2, and is fixed to a plate 7 formed with a pointer 12 which co-operates with a temperature scale 13. The plate 7 is slidable along a guideway 9 on the insulating backing 4, and is held in adjusted position by a screw 8 and nut 11.
