Title: Method and Apparatus for Making a Magnetic Survey
IPC: G01R33/025
Filed: 1967-12-05
Abstract: 1,192,076. Magnetic surveying. GULF RESEARCH & DEVELOPMENT CO. Dec. 5, 1967 [Dec. 8, 1966], No. 55252/67. Heading G1N. A magnetic survey system uses difference signals from a pair of magnetometers spaced a short distance apart, (e.g. at the nose and tail of an aircraft) to concel out time-variations in the earths magnetic field. This signal is integrated to produce a total intensity curve which may have its level adjusted so that certain points correspond with one of the original magnetometer records to compensate for drift introduced e.g. by instrument noise. To maintain the magnetometers parallel to the original bedding, and correct for crabbing of the survey aircraft in a cross-wind;- Fig. 1 (not shown) the magnetometers are mounted on "stingers" which can be sleeved relative to the aircraft; or Fig. 2 (not shown) they are mounted in a towed glider which is steerable from the aircraft; or Fig. 3 (not shown) they are mounted to be simultaneously movable around a ring attached to the glider. Similar provision may be made to correct for cross-current if they are towed by a ship Fig.4 (not shown).

Title: Tensioning of underwater riser pipe
IPC: E21B17/01
Filed: 1970-11-23
Abstract: 1319970 Wells &c JOY MFG CO 23 Nov 1970 [15 Dec 1969] 55605/70 Heading E1F A marine riser pipe is maintained in tension by applying to a lower part of the pipe a downwardly acting hydrostatic force and a smaller upwardly acting fluid pressure force. The lower part 38 of the riser pipe 16 has a piston 40 reciprocable in a cylinder 28 fixed to a submerged wellhead (not shown). Holes 46 permit the hydrostatic head of drilling fluid in the riser pipe to act on the upper side of the piston, and a pipe 60 leading to above the water's surface permits atmospheric pressure to act on the lower side of the piston. Fluid passing through the pipe 60 and a chamber 72 (Fig. 4) may be pumped by a pump 74 to or from the lower side of the piston or, alternatively, a valve 73 may be opened to supply water to the lower side of the piston. In a modification (Fig. 5 not shown) the holes 46 are replaced by holes through the upper end of the cylinder so that the upper side of the piston is subjected to the hydrostatic head of the water. The riser pipe may extend from an underwater production and storage system.

Title: Bit timing regeneration
IPC: H04L7/033
Filed: 1972-12-06
Abstract: 1410637 Digital transmission: extracting clock signal TELEFONAKTIEBOLAGET L M ERICSSON 6 Dec 1972 [6 Dec 1971] 56407/72 Heading H4P To recover binary signals from multilevel signals, a receiver generates a plurality of clock trains at different phases and selects the one giving the most consistent result. The threelevel signal cn, Fig. 3a, has correlative properties, being produced (K, Fig. 2, not shown) by an exclusive OR gate (EE) whose output B is fed back through a one-bit delay to one input and is also delayed by two bits and subtracted from the undelayed output B, whereby each bit of the transmitted signal is related to adjacent bits (hence the correlation) as well as to the binary input an. At the receiver (Fig. 6, not shown) a level detector A2 (details Fig. 8, not shown) derives 1s from + 1 and - 1 in the received signal, and 0s from 0 levels therein, to give a binary signal Zn, Fig. 3b. The binary signal Zn is then sampled (at V) by clock pulse tn to give the original binary signal an. The clock generator (TG2) produces two outputs of opposite phase, one of which is to be adopted as tn and is driven by an oscillator (SKR) phase-locked to pulses derived by a zero level detector ND which produces the pulses nn each time the received signal reaches or leaves 0. Some zero crossovers however 1, 2, 3 do not correspond to bit times (which are shown as black dots) and pulses nnf derived from these could lock a single output clock to an erroneous phase in which sampling would produce a binary 0 at times 1, 2, 3, instead of a 1 as required by the original signal an. This erroneous phase is one of the TG2 outputs, and so both outputs are used to clock respective error detecting circuits F1, F2 (details Fig. 9, not show) in which an exclusive OR (EE1) simulates the first stage of the transmitter encoding operation to give a signal (like bn) intermediate the binary and three-level signals. If the clock phase is correct this intermediate signal will be directly related to the three-level received signal, and so this is supplied in the form of two binary signals xn and yn (from the detector A2) to JK flip-flops (V2, V3). If the relation is correct, the output hn goes to 1; the outputs h of both error detectors are then integrated (I1, I2), the smallest error being selected (at B) to connect the appropriate clock output from TG2 (through SW) to the sampler (V). In a modification (Fig. 7, not shown) a hold circuit (H, and Fig. 10, not shown) retains the last state of switch (SW), should the error detector outputs become equal due to noise conditions for example.
