Title: Method for eliminating selected noise disturbances from seismic recordings
IPC: G01V1/28
Filed: 1969-09-22
Abstract: 1285193 Seismic prospecting PETTY GEOPHYSICAL ENG CO 22 Sept 1969 [30 Sept 1968] 46484/69 Heading H4D In a system for enhancing the signal-to-noise ratio of seismic signals, the field procedure and subsequent data processing are together such as to attenuate noise of wavelengths intermediate between those attenuated by the geometry of a geophone array and those attenuated by stacking.  In the Fig. 2 field procedure example a line of four sources (explosive, weight-drop, gas gun, compressed air or vibrator type) at position 1 is shot into geophone groups A, B &c., whose centres are spaced along a traverse, and the geophone outputs are recorded. The source line is then moved successively to positions 2 (not shown) to 36 and separate recordings are made for each position of the line, giving 36 records per geophone group. Recording drums with movable heads (Fig. 3, not shown) are used to apply to the records static corrections and either full normal moveout (NMO) corrections or fixed time corrections approximating the NMO ones. Variable gain circuits then apply respective amplitude weighting factors to the corrected records of selected geophone groups (e.g. groups A, B, C) whereby records relating to the centre of the selected geophone spread (i.e. the centre of group B in this case) are given most emphasis and those relating to the ends of the spread are given the least emphasis. These weighting factors are in accordance with a specified mathematical relationship. The weighted signals are composited and the weighting and compositing are repeated for other selected geophone groups (e.g. B, C, D, then C, D, E, and so on). The composited signals are then stacked, after the application of full NMO corrections if not previously made. The number of sources, source locations, and geophone group selection may be varied according to the bandwidth of the noise to be attenuated (as determined from a preliminary survey).

Abstract: 1,156,192. Magnetic storage elements. INTERNATIONAL BUSINESS MACHINES CORP. 20 Oct., 1966 [2 Nov., 1965], No. 46893/66. Heading H1T. [Also in Division H3] In a magnetic anisotropic thin film store an electrically conducting non-magnetic screen is placed between a thin film element of the store and a word drive line so as to shield part of the element. A single thin film element 21, Fig. 3c, having an easy axis in the direction parallel to the word line 26 is positioned on a ground plane 23 and to prevent flux being trapped within the ground plane ferromagnetic layer 24 is provided. Part of the film 21 is covered by a copper screen 25, which in the arrangement shown lies in the same plane as sense line 28 and bit line 27. To write information into the film a word write pulse is applied to word drive line 26, to rotate the vector of magnetization into the hard axis, coincidently with a bit pulse of the required polarity applied to bit line 27. The duration and amplitude of the word pulse is such that the whole of film 21 is switched and this pulse terminates before the bit pulse. Information is read out by applying only a word pulse which is of shorter duration than the write pulse, the resulting rotation of the magnetization vector of the thin film producing eddy currents within the screen which generate an opposing field between screen 25 and ground plane 23. This field causes the magnetization in the part of the film covered by the screen to rotate slowly compared with that outside the screen so that the part of the film under the screen 25 acts as a store region and the part outside as a read region. When the read pulse ceases the slowly rotating part of the film returns to the easy axis and generates a magnetic field strong enough to cause the fast switching part of the film to return to its original position in the easy direction. The rotation of the magnetization vector in the fast switching part induces an output signal in sense line 28. A plurality of the elements may be arranged in a matrix, Fig. 6a, with the word 26, bit 27, and sense 28 lines arranged as shown with part of the films 21, being screened by 25. In the arrangement of Fig. 6b (not shown), one screen 25 partly covers film elements in two adjacent columns.

Title: Improved stall-correcting apparatus for aircraft
Inventor: GRIMSHAW RICHARD JAMES ERIC
IPC: B64D45/00
Filed: 1963-12-03
Abstract: 1,076,188. Stall correcting apparatus. BRITISH AIRCRAFT CORPORATION (OPERATING) Ltd. March 2, 1965 [Dec. 3, 1963], No. 47701/63. Headings: B7G and B7W. [Also in Division F1] An aircraft has incidence sensing means arranged, when the incidence exceeds a given value, to actuate a stall warning device such as a stick shaker, and afterwards to actuate elevators to pitch the aircraft nose-down. The elevators may be actuated a predetermined time after the warning, to allow the pilot to correct, or at an incidence higher than the warning incidence. The signal to the elevators may be modified by a generator (20) in accordance with variations, e.g. in flap angle. The pilot's elevator control may comprise mechanical links (15) to spring links (18) and power actuated units (16) coupled to the elevators (Figs. 1 and 2, not shown), and the pitch signal from the incidence sensing means (10) may be applied either through an autopilot (19, Fig. 1) or directly (Fig. 2) to lock the spring links (18) and to operate the units (16). In another embodiment (Fig. 3, not shown), two sensors (30, 31) give warning of the approach of a stall and two further sensors (34, 35), are operative at a higher incidence. The sensors (30, 31) actuate relays (44, 45, 49, 50) so that signals from the sensors (34, 35) cause klaxons (46, 47) to be sounded and valves (55, 56) to be opened, permitting compressed gas to flow to a ram (36) to push the control column. Where the aircraft has turbo-jet engines which are liable to flame out at high incidence, the sensors (30, 31) may also operate igniters in the engines. The signals from the sensors are modified by phase advance networks and altitude switches to compensate for rate of change of incidence and for altitude. The ram (Fig. 4, not shown), has two pistons in series the piston (63) having a hollow rod (66) which abuts, and allows compressed nitrogen to pass to, a second piston (69) carrying the actuating rod (70). Thus initially, fluid pressure is applied to both pistons. The travel of the piston (63) is limited by an abutment (68), and then only the piston (69) produces a load on the rod (70), and this is further reduced by a precompressed spring (74). The force applied to the control column is therefore reduced from its initial value to avoid an excessive negative " g " on the aircraft.
