Title: Improvements in or relating to telemetering systems
IPC: G08C19/26
Filed: 1944-03-28
Abstract: 575,568. Telemetering systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and STONER, C. R. P. March 28, 1944, No. 5669. [Class 40 (i)] In a telemetering system in which impulses are transmitted at a rate proportional to the measured quantity, the rate of transmission is determined by measuring the length of the interval between impulses, preferably by measuring the voltage acquired by a condenser during the interval. As shown, the impulses are repeated by a relay A to relays ML, CR in series, a relay CO co-operating to cause the odd impulses to operate the energising and the even impulses the releasing winding of ML, which is of the type described in Specification 515,529 and is held by a permanent magnet in the position to which it was last set. As a result a condenser QA is discharged over a low resistance YB by each odd impulse, charged over resistance YB by each odd impulse, charged over resistance YA during the subsequent interval, and is connected to an electrostatic voltmeter ESV by each even impulse, remaining connected during the following interval. A condenser QB is similarly charged during the intervals following the even impulses and connected to the voltmeter by the odd impulses. As shown, the voltmeter indicates the difference between the condenser voltage and the charging voltage to give a large deflection for a high rate of impulsing, but the actual condenser voltage may be communicated to the voltmeter.
