Title: Compass deviation error measurement and correction
IPC: G01C17/38
Filed: 1961-12-29
Abstract: 1,006,326. Compass swinging. SPERRY RAND CORPORATION. Dec. 29, 1961 [Jan. 25,1961], No. 46701/61. Heading G1N. Apparatus for swinging the flux gate compass of an aircraft without having to rotate the aircraft comprises means for producing a local field to neutralize the earth's field, and energizing separately each of the three coils of the startor of the flux gate valve with direct current in both directions to provide six known magnetic field directions at which the compass deviations may be read from a repeater compass. As shown (Fig. 1), a flux gate compass 10 is connected to a directional gyrocompass 19 to precess the latter when deviations occur between their readings, whereby the compass card 23 on unit 19 indicates the heading of the craft as measured by the flux gate compass 10. The aircraft carrying the apparatus is initially located in an area relatively free outside magnetic disturbances and pointed due North. The flux gate unit 10 is removed from the aircraft and rotated on a platform (Fig. 4, not shown) until the compass card 23 also indicates due North. A direct current is then fed from bottom 37 through the windings 13,14,15 of the compass 10 to produce a field which exactly neutralizes the earths field, the EW components in coils 14, 15 being balanced by the slider of potentiometer 40 as known by a null indication on meter 41, with switch S2 in its lower position, and the magnitude of the D.C. adjusted by series rheostat 49 to that value where the auxiliary magnetic field produced by this current exactly neutralizes the earth's field, as shown by meter 41 with switch S2 in its upper position. The flux gate unit 10 is now restored to its normal location on the aircraft still pointing due North, with the earth's field neutralized. Apparatus comprising batteries 136, 165, 131 and centre-tapped resistors 40, 134 and 139 connected across coils 13, 14, 15 supplies currents through the coils producing any one of six magnetic fields accurately displaced by 60 degrees from each other, and the corresponding readings on compass card 23 show the deviations at each direction due to the magnetic structure of the aircraft. The deviations may be removed by compensating currents through windings 13, 14, 15 obtained from a battery 157 via potentiometers 154, 162, 163. In another embodiment (Fig. 2) where the aircraft is not made to point due North, a monitoring flux value 54 external to the aircraft is used to neutralize the earth's field by locating it in line with the aircraft and flux gate 10, but with the signals in its coils 180 degrees out of phase with those in the windings of unit 10. The two flux valves 10, 54 are connected in parallel or in series (Fig. 3, not shown) to a repeater 56, and the magnitudes of the signals in the windings of the monitoring unit adjusted by potentiometers 87, 82, 92 until the figure received at repeater 56, shown on meter 102, is zero. Specifications 599,428, 638,971 and 850,596 are referred to.

An isostatic moulding press for forming articles from powdered materials, comprises an outer fixed casing 10, having a feed inlet 11 and an outlet 12, within which is rotatably located an inner member 13. One portion of member 13 is provided with two diametrically oppositely disposed cored mould cavities 14, each of which has an expansible elastic liner, whilst the other portion is of reduced diameter and is provided with fluid containing radial bores which connect via passages 40 with each mould cavity. Radial pistons 29 are slidable within the bores and are actuated, through rollers 33, by a cam ring 25 eccentrically disposed within the space between the casing 10 and the reduced portion of the member 13. In operation, as member 13 rotates, a mould is filled at 11 and is carried round within the casing 10 to the outlet 12.
