Title: Borehole Survey System
IPC: E21B47/022
Filed: 1981-10-01
Abstract: A system for surveying a borehole or mine shaft to determine its trajectory uses a sensing probe with two spaced sets of accelerometers in sections 22, 23 measuring the components of the gravity vector along orthogonal axes at successive positions along the borehole 20. The two sets of accelerometers are connected by a pipe or cable 24 which is flexible to bend but torsionally stiff. The angular orientation of the two accelerometer sets relative to each other about the borehole axis is fixed by the pipe or cable 24 so that any difference in orientation of the two sets is a function of the local trajectory of the borehole. Two sets of accelerometer output signals representing gravity vector components at positions spaced apart along the axis of the borehole are utilized to derive the borehole inclination at each position as well as the change in borehole azimuth angle between the positions of the accelerometer sets. The accelerometer signals and a signal representing the position of the probe along the length of the borehole, are combined to provide a three dimensional representation of the borehole trajectory, relative to a reference point, e.g. the termination of the borehole at the surface. <IMAGE>

Title: Stabilization and Control of a Projectile
IPC: F41G7/26
Filed: 1982-02-08
Abstract: A projectile is stabilized by means of a beam of polarized light which is directed at the projectile, and whose direction of polarization is cyclically varied about a reference direction. The projectile carries two polarization analysers (10, 11) positioned with their preferred transmission directions mutually perpendicular, and two photo detectors (12, 13) are positioned to receive light transmitted from respective analysers (10, 11). The signals generated by the photo detectors (12, 13) are amplified and processed in a processing unit (14) to provide a flight correction signal to stabilize and/or control the movement of the projectile about its roll axis. The sign of the correction signal is determined by the signal processing unit by comparing the relative values of detected optical signals from one of the detectors (12, 13) in pairs of successive cycles of variation of the polarization direction of the incident polarized light beam, the processing unit (14) being preliminarily synchronized. <IMAGE>

Title: Semicontinuous casting process
Inventor: KORSHUNOV EVGENY ALEXEEVICH
IPC: B22D7/00
Filed: 1982-03-23
Abstract: The process comprises stepwise uphill feeding of a molten metal 4 into a mould 1 up to a dummy bar 2, holding the metal 4 in the mould until a skin 6 of casting is formed to a preset thickness, withdrawing the casting from the mould 1 for a given length and concurrently feeding molten metal into the mould 1 in an amount equivalent in volume to a given length of withdrawal. After initial feeding of the molten metal 4 to the mould 1 and after that following each successive step of the casting withdrawal from the mould 1, the feeding of the molten metal 4 is continued and the latter is expelled beyond the boundary of the dummy bar 2 in volume equalling 0.1 to 0.9 times the volumetric capacity of the mould 1. During the holding period, a part of the molten metal 4 is returned, at least once, into the casting being formed and then is again removed beyond the boundary of the dummy bar 2. Before the casting formation process has been completed, a major part of the metal volume is introduced into the casting being formed, whereupon the feeding of molten metal is discontinued until complete solidification of the casting. <IMAGE>

Title: Frequency synthesizer with a low-noise, low-frequency output
Inventor: CONNELL PETER PATRICK RAYMOND
IPC: H03B21/02
Filed: 1982-10-01
Abstract: A frequency synthesizer block 5 employs a reference frequency, e.g. at 100 MHz, from a reference frequency unit 8 and derives an output on a line 18 variable in the range 600 to 1200 MHz, say, which appears at an output terminal 22. Lower range outputs are derived by division 24, 30 and appear at output terminals 28 and 32. A still lower range appears at terminal 48, but this is produced by a mixer 36. The mixer subtracts a fixed frequency derived from the reference frequency unit 8 with a frequency in a selected band range from the synthesizer output 28. Wide-band phase-locked loops or other techniques are used throughout the system so that noise on the reference frequency appears in phase at both inputs of the mixer 36 and is subtracted by the mixer so as to produce a very low noise output at terminal 48. <IMAGE>

Title: An aircraft undercarriage
Inventor: JENKINS STANLEY FREDERICK NOEL
IPC: B64C25/58
Filed: 1983-01-28
Abstract: The undercarriage includes a pair of pivotally interconnected undercarriage legs 32, 33, the latter of which carries a ground wheel 15. A strut 14 extends between lugs 31, 34 on the legs. The strut may either be frangible or fluid operable and normally inhibits relative pivotal movement of the legs. However, if a load in excess of a desired load is applied to the undercarriage, the strut will operate to permit such relative movement. At the limit of such relative movement the lowest point L of the wheel 15 will be below the lowest point P of the undercarriage. The strut 14 may be an actuator used in retracting the undercarriage with a mechanical lock to hold the strut rigid for landing. An excess load would cause the lock to fail. The undercarriage is intended for a helicopter. <IMAGE>

IPC: H03G5/04
Filed: 1981-08-26
Abstract: A signal transfer and processing system for use with a transmission line. The system includes transmission line interface circuitry (A) and signal processing circuitry (100). The processing circuitry has an input (113) for receiving a signal to be processed, and a signal output (117) for providing a processed signal for further use. An input bandpass filter (119, SW7) filters the signal to be processed to selectively limit bandwidth thereof. A primary active frequency control (123) selectively controls the relative level of the signal provided from said primary bandpass filter means (123) for selectively controlling the relative level of signal dynamics within a plurality of different frequency bands thereby to provide a frequency controlled signal. A primary dynamic control circuit (127) dynamically compresses the frequency controlled signal to provide a primarily compressed signal. A secondary active frequency control (135) selectively controls the relative level of the primarily compressed signal within a plurality of different frequency bands to provide a frequency controlled primarily compressed signal. A secondary dynamic control circuit (137) dynamically compresses the last-said signal, supplying a secondarily compressed signal. A feedback circuit (128, 129, 140) interconnected between the primary and secondary dynamic control circuits limits dynamic compression by the primary dynamic control circuit as a time-delayed function of increase in the level of the secondarily compressed signal. An output bandpass filter (152, SW8) filters the secondarily compressed signal to selectively limit its bandwidth. The interface circuitry includes switching circuits (30) for interconnection of signal input and signal output of the signal processing circuitry with the transmission line.
