Title: Method and apparatus for dynamically weighing objects in motion
IPC: G01G3/147
Filed: 1964-10-01
Abstract: 1,077,508. Electric selective signalling. CANADIAN NATIONAL RAILWAY CO. Oct. 1, 1964 [June 15, 1964], No. 39988/64. Heading G4H. [Also in Division G1] Apparatus for weighing a moving, bouncing vehicle (11, Fig. 1, not shown) comprises load cells (15), on which a weigh-bridge (12) is supported, producing a signal, Fig. 2 (not shown), an integrator receiving this signal for a predetermined period of time to reduce the amplitudes of the oscillatory components, the output of the integrator being measured to indicate the weight of the vehicle. The signal, after amplification at (19, Fig. 4, not shown) is applied to a filter (20) which produces in two seconds an output (e 0 ) in which the oscillatory part has been reduced to 1/ 13 th of what it was. Potentiometer (21) reduces this signal to 1.00 volts which is applied to an integrator (22) which produces a signal of 2 volts for an integration period of one second. A timer (24) is controlled by switch (25) which closes when the vehicle has been on the weigh-bridge for two seconds to enable the integrator (22) for one second. The integrator then holds its signal and a command from the timer causes digital voltmeter (23) to indicate the true static weight of the vehicle. This value may then be printed out. In another form a digital converter is used in place of integrator (22), the converter producing 10,000 pulses per second for a 1 volt input. This signal passes to a pulse doubler producing 20,000 pulses per second which are applied to a digital counter started by the track switch and counting for a period of one second set exactly by a crystal clock. The output of the counter passes to a pointer. These forms depend for their accuracy upon the accuracy of the excitation supply voltage of the load cells. In the form of Fig. 6 (not shown) this is avoided by providing a second integrator (31) for the supply voltage which is controlled for the same integration period as integrator (22). The ratio of the outputs of the two integrators is given by a digital ratiometer (32). In the form of Fig. 7 (not shown) a digital integrator (26) is shown as described above but the counting period of counter (34) is determined by the input voltage (E) which is applied through a potentiometer (30) to digital integrator (33). This produces 10,000 per second for normal input voltage. The counter (34) is started by the track switch and counts until a count of 10,000 is reached in counter (39). The result is printed out as before.
