Abstract
1,056,082. Electric selective signalling. BROWN, BOVERI & CO. Ltd. Feb. 9, 1965 [Feb. 11, 1964], No. 5549/65. Heading G4H. A switch mechanism of an electricallypowered vehicle is moved until a voltage corresponding to its position is equal to a second voltage derived from a coded value which represents the desired position and is derived from a plurality of two-state switching devices. The switching devices may be cams, or contactless switches in which a rotatable member can alter the coupling between two inductances and thereby the degree of damping of oscillations in a circuit. The switching devices provide the desired position in a progressive (i.e. monophylic) code which is converted to pure binary using exclusive-or logic (Fig. 3, not shown) and then used to produce a D.C. voltage (said second voltage) using weighted resistors. A similar arrangement may be used to produce the voltage representing the actual position.
