Title: Improvements in and relating to the testing of a pair of conductors within a multi-conductor arrangement
IPC: G01R31/50
Filed: 1980-02-26
Abstract: One conductor of each conductor pair has associated with it at the other end of the arrangement, its own unique marker resistance having different values in the forward and reverse directions to identify one the two digits of the number of the pair. First, a continuity test is made by including the pair in series in one arm of a resistance bridge, advancing to an earth test if the output from the bridge is satisfactory, by including the pair in parallel with one another and in series with a resistance and an earth return in one arm of the bridge and advancing to a digit identification test if the output from the bridge continues to be satisfactory. The digit identification is made by including the pair in series in one arm of a resistance bridge and determining the value of the marker resistance in the forward and reverse directions. An advantage of such a method is that it can be made to proceed automatically. <IMAGE>

Patent GB-2120062-A (GB)
Title: Yieldable plough body mounting
Inventor: DOWDESWELL CHARLES VERNON ROGE
IPC: A01B61/04
Filed: 1982-05-18
Abstract: Maximum initial spring loading is effected against initial upward yielding movement of an arm (1) carrying a plough body (11) on encountering an obstruction in the ground. This is achieved by lever action linkage (5) consisting of a bell crank (50) pivotally mounted by a bracket (15) from the rear of the arm (1) and pivotally connected to the rear end of a connecting rod (40) which extends along the arm (1) from anchorage (42) to the support structure (2,3). The bell crank lever (50) is also pivotally connected by a further lever (55) to a return spring (44), the lever being intermediately supported from the bracket (15) by a link (53) or roller for angular movement and also for generally endwise movement. On initial upward yielding movement of the arm (1) angular movement is imparted to the lever (55) for initial rapid extension of the spring (44). Thereafter further generally endwise movement of the lever (55) results in little or no further spring loading against the arm (1) on continued upward movement of the latter. <IMAGE>
