Title: Pole changing induction electrical machines
IPC: H02K17/06
Filed: 1979-08-30
Abstract: An induction machine has a core with a number of slots (s) and a double layer winding comprising two phase-windings (A, B) for two-phase operation (Fig. 14a) at a first pole number (2p) using a capacitor C/p. the top layer has conductors assigned to s/4p successive slots for each pole of each of the two phase-windings. Switching means is provided for reconnecting coils or groups of coils of the two phase-windings by pole amplitude modulation to produce a single phase-winding (Fig. 14b) using a centrifugal switch C/S at a second, and possibly also a third, pole number. The positions of the modulating waves producing the second and third pole numbers may be different, e.g. mutually displaced by greater or less than 90 DEG  on the scale k THETA , where k is the number of modulating pole pairs in one revolution and  THETA  is mechanical degrees around the axis. The top layer may have conductors assigned to s/2p2 successive slots for each pole of the second pole number (2p2), except that one or more coils providing conductors in the top layer adjacent one end of each of alternate s/2P2 groups are reversed. Separate modulating waves mutually displaced by less than 180 DEG  may produce a second pole number. <IMAGE>

Title: Coding, decoding, digital data
IPC: G11B20/14
Filed: 1979-12-18
Abstract: In a technique for the transmission or for the non-saturating recording and replaying of serial digital data, the data is converted into a coded signal in which each digit is represented by a respective pulse code having a positive value and a negative value, the time integral of each pulse code being equal to zero as shown in Figure 1. In order to decode this signal, it is applied to a threshold device for sensing when it passes upper and lower thresholds and for producing an output signal having upper and lower levels in response thereto (Figure 3b). This output signal is applied to an integrator which generates a triangular signal having rising ramps corresponding to one of the levels of the output signal and falling ramps corresponding to the other level. A threshold detector receives the triangular signal and generates therefrom a decoded signal and a clock signal. <IMAGE>
