Abstract

Abstract A weighing device for attachment to and for providing an indication of the load applied to a vehicle axle to which the load is applied at a pair of spaced points comprises two pairs of sensing means, the sensing means of one pair being mounted on opposite sides of one of said points, each of said sensing means providing an electrical signal indicative of the bending moment at its particular position, and the device including electrical circuit means for processing the signals produced by the sensing means to provide an indication of the total load applied to the axle.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 117 words
A weighing device for attachment to and for providing an indication of the load applied to a vehicle axle to which the load is applied at a pair of spaced points, the device comprising two pairs of sensing means for mounting on the axle, the sensing means of one pair being positioned on opposite sides of one of said points, and the sensing means of the other pair being positioned on opposite sides of the other of said points, each of said sensing means providing an electrical signal indicative of the bending moment at its particular position, and electrical circuit means for processing said signals to provide an indication of the total load applied to the axle.
Claim 2
Dependent Claim 117 words
A weighing device for attachment to and for providing an indication of the load applied to a vehicle axle to which the load is applied at a pair of spaced points, the device comprising two pairs of sensing means for mounting on the axle, the sensing means of one pair being positioned on opposite sides of one of said points, and the sensing means of the other pair being positioned on opposite sides of the other of said points, each of said sensing means providing an electrical signal indicative of the bending moment at its particular position, and electrical circuit means for processing said signals to provide an indication of the total load applied to the axle.
Claim 3
Dependent Claim 18 words
A weighing device as claimed in claim 1 in which said electrical circuit means is an analogue circuit.
Claim 4
Dependent Claim 165 words
A weighing device for attachment to and for providing an indication of the load applied to a vehicle axle to which the load is applied at a pair of spaced points intermediate the ends of the axle, the device comprising two pairs of sensing means for mounting on the axle, one pair of sensing means being adapted to be mounted on the axle with one of said points located between the two sensing means of the one pair, the other pair of sensing means being adapted to be mounted on the axle spaced from the first pair and having the other of said points located between the two sensing means of the other pair, each of said sensing means providing an electrical signal indicative of the bending moment at its particular position, and electrical circuit means for processing said signals to provide an indication of the total load applied to the axle substantially independent of the position of the axle with respect to the horizontal.
Claim 5
Dependent Claim 165 words
A weighing device for attachment to and for providing an indication of the load applied to a vehicle axle to which the load is applied at a pair of spaced points intermediate the ends of the axle, the device comprising two pairs of sensing means for mounting on the axle, one pair of sensing means being adapted to be mounted on the axle with one of said points located between the two sensing means of the one pair, the other pair of sensing means being adapted to be mounted on the axle spaced from the first pair and having the other of said points located between the two sensing means of the other pair, each of said sensing means providing an electrical signal indicative of the bending moment at its particular position, and electrical circuit means for processing said signals to provide an indication of the total load applied to the axle substantially independent of the position of the axle with respect to the horizontal.
Claim 6
Dependent Claim 66 words
The invention in accordance with claim 3 in which said electrical circuit means is an analogue circuit wherein signals from the sensing means are supplied to the circuit in inverted form, the circuit including a number of function generators arranged to perform interrelated functions to produce an output indicative of the total applied loading on the axle independent of the movement of the points of support.
