Title: Correction of Errors in Railway Track
IPC: E01B35/00
Filed: 1979-10-31
Abstract: A magnetic tape record 29 of the actual state of the track, obtained from a recording vehicle, is used to control a correcting machine. The tape is synchronized with the travel of the machine by a sensor on a wheel 26 controlling the tape drive 28. Head 35 reads off alignment at intervals and the averager 44 generates a desired track alignment condition. Comparator 45 compares alignment at a point B, derived from tape B' by head 36, with desired alignment and feeds error signal to control hydraulic ram 48 for lateral adjustment of track. The signal from averager 44 representing track curvature is combined with speed input 51 to generate desired cross level for comparison with signal from head 37. The resulting error signal then controls lifting ram 54 or 55. Processing of the original record to obtain desired track condition or to obtain a record of error signals may be carried out in advance to produce a tape for control of the correcting machine.

Title: Calorimeters for and methods of monitoring calorific values of gases.
IPC: G01N25/28
Filed: 1983-06-23
Abstract: A calorimeter and method of obtaining the calorific value of a test gas comprises a pair of constant flow pumps one for supplying air at known volumetric flow and the other for supplying a test gas at known volumetric flow. The known volumetric flow of air is maintained at a level sufficient to provide enough oxygen to fully burn all oxidizable components of the test gas. The air and test gas are mixed and catalytically burned in a heated block and the combustion products are thereafter supplied to an electrochemical oxygen measuring cell which measures the remaining oxygen in the mixture. A circuit arrangement is utilized to obtain a value proportional to the difference between the remaining oxygen and original amount of oxygen which value is proportional to the amount of oxygen utilized and in turn proportional to calorific value of the test gas.
