An oil-filled cable of the type having a non - circular metal sheath of substantial elasticity is made by drawing the cable core mto a metal tube of circular cross-section and then rolling or drawing the tube down to form a non- circular sheath which is subsequently evacuated and filled with oil. Where the cable has two or more cores twisted together the corresponding twist may be imparted to the sheath during the drawing-down operation. A three-core cable in which the cores 1a, 1b, 1c lie parallel with each other is made by drawing the cores into a circular tube 3, (Fig. 7), which may then be drawn down to triangular shape (Fig. 9) or flat shape (Fig. 12).

Title: Stepping motor excitation circuitry
IPC: H02P8/14
Filed: 1979-02-28
Abstract: In circuitry for driving stepping motor coils through a sequence of discrete steps, each coil 11 of the stepping motor has drive circuitry which includes a first, low power circuit 12 having a regulated power supply 13, for supplying a substantially constant voltage Vb and a second, high power circuit 15 having a transistor emitter follower 14, the substantially constant voltage being supplied to the base thereof. The second circuit can use a substantially unregulated power supply 16, the voltage of which may vary considerably. Such second circuit, however, supplies a substantially constant current pulse to its associated stepping motor winding even if the unregulated power supply voltage varies over a relatively wide range. The same circuit configuration is used for each winding so that the current pulses supplied to all windings are substantially the same even if the winding resistances differ from winding to winding. Such circuitry is can be used for positioning the read/write heads of a disk storage device in a data processing system wherein rapid and accurate positioning of such heads relative to the disk surface is required. The heads can be controlled to move along velocity profile, to be stopped at a desired position substantially at zero velocity so that little or no oscillation thereof occurs. <IMAGE>

Title: A method and apparatus for removing noise in a LORAN-C navigation receiver
IPC: G01S1/24
Filed: 1980-10-09
Abstract: Noise generated in the front end of a LORAN-C receiver that causes noise bias interfering with carrier cycle detection is effectively removed by periodically shifting the phase of all received signals by 180 DEG  in the front end of the receiver and then removing any phase shift elsewhere in the receiver where noise is no longer a problem but before the phase shift can affect time difference of signal arrival measurements normally made in LORAN-C receivers. In this manner, noise generated in the front end of the receiver is averaged out and doesn't introduce bias levels to the received signal. <IMAGE>
