Title: Method of removing the effect of multiple and other non-primary reflections in seismic reflection shooting
IPC: G01V1/28
Filed: 1966-09-05
Abstract: 1,123,328. Geophysical prospecting. GULF RESEARCH & DEVELOPMENT CO. 5 Sept., 1966 [13 Sept., 1965], No. 39564/66. Heading H4D. [Also in Division G2] Non-primary reflections or other undesired ordered seismic events are removed from a seismic reflection record by applying static and normal movement corrections for primary reflections to a plurality of seismograms obtained using common subsurface reflection points but different shot-detector spacings, arranging the corrected seismograms in alignment side-by-side in order of progressive change of shot-detector spacing, preparing a transparency of the arrangement, and optically filtering the transparency with a filter which is arranged in a Fourier plane and occludes Fourier transform components resulting from events on the transparency having alignment differing from the alignment of primary reflections. For removing "multiple" reflections, the seismograms are obtained using a plurality of shot and detector positions located symmetrically about each common reflection point, are corrected, and are arranged in side-by-side groups (30, 35) (Fig. 2), each group corresponding to a respective common reflection point with shot-detector spacing increasing across the group. Primary reflections are then in continuous alignment (45) across the arrangement, but multiple reflections are due to residual movement errors, in discontinuous alignments (46) across each group only. The transparency of this arrangement is illuminated (e.g. with laser light) and its Fourier transform is obtained in plane 55 (Fig. 3). A filter placed in plane 55 and having an opaque sector at 90‹ (measured round the optic axis of the Fig. 3 system) to the multiple reflection alignments (46) occludes those Fourier components resulting from the multiple reflection events but passes primary reflection data to output plane 54 where it is photographed. For removing "ghost" reflections, the seismograms are obtained by firing shots at a plurality of depths for each common reflection point, are corrected, and are grouped with shot depth increasing across each group. The ghost reflections then appear, due to residual static errors, as discontinuous alignments across each group only and are optically filtered out as above. Where the undesired event to be removed is a horizontally travelling "noise" event, a group of seismograms is recorded using a plurality of relatively small shot-detector horizontal spacings and is filtered as above. Where subsurface reflecting horizons show considerable dip, each seismogram group may be filtered separately and a complete seismic section is then assembled from the filtered groups.

Abstract: 925,302. Rotary wing aircraft. K. H. WALLIS. Nov. 15, 1961 [Nov. 18, 1960], No. 39641/60. Class 4. An auto-rotating rotary winged aircraft includes rotor blades carried by a rotor spindle running upon bearings which are mounted on a gimbal system having one spindle arranged to allow movement of the rotor spindle in the pitching plane whilst another spindle allows movement in or about the rolling plane, characterised in that the pitch spindle axis is arranged forwardly of the axis of, and below, the rotor spindle. The aircraft structure, rotor drive and control mechanism are as described in Specification 925,301. The fixed rotorsupporting structural pylon is shown at 23 and the stub shaft mounting for the rotor head bearings at 40. A bifurcated extension 45 to pylon 23 carries a bush 44 for a shaft 43 parallel to the roll axis of the aircraft, the shaft being part of a yoke 42 which carries a pivot 47 for a control plate 41 to which shaft 40 is attached, the control plate being connected by rods (not shown) to the control column whereby it may be rocked about pivot 47 to provide control in pitch. Since pivot 47 is forward of shaft 40 drag loads on the rotor are compensated to some extent by the weight of the aircraft and to allow for aerodynamic drag shaft 43 is biased by a spring 46 which will become compressed as forward speed increases. Specification 925,303 also is referred to.

Abstract: 1,172,083. Automatic frequency control systems; multiplex pulse code signalling. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. 5 Sept., 1967 [6 Sept., 1966], No. 39869/66. Headings H3A and H4L. A local oscillator SO, Fig. 1, is synchronized to the mean frequency of a number of input signals of the same nominal frequency by means of a reversible counter AS which is advanced one step for each input of higher frequency and reversed one step for each input of lower frequency, the output of the counter being converted to an analogue signal in unit DAC and fed to a device FC controlling the frequency of the oscillator. Fig. 1 shows the application to a PCM system wherein inputs from five different exchanges on lines 1-5 are converted in units BE to square waves which are differentiated to form two trains of pulses, A and B, at the leading and trailing edges of the square waves. One of these trains is selected by means of C and D pulses from the local oscillator and combined in units CD to produce an output at X to increase the count of counter AS or at W to decrease the count according to the sense of the frequency difference. Combining pulse trains, Fig. 3.-Assuming the bi-stable Y is reset, gate 63 is open and the A pulses pass to the output E. If an A pulse coincides with a C pulse from the local oscillator, the gate G1 is opened and Y is set thereby allowing the next A pulse to set the bi-stable Z, thereby allowing the B pulses to pass to the output E. When changing from A pulses to B pulses there is an interval of 1¢ bits between successive pulses, and when changing from B to A there is an interval of ¢ bit between successive pulses. In a modified circuit, Fig. 4 (not shown), the gate 66 and bi-stable Z are replaced by a delay unit D having a delay greater than ¢ bit and connected between the set output of Y and gates G2 and G4. Frequency error detection, Fig. 5.-The bistable W is set by narrow D pulses from the local oscillator and reset by E pulses which are the output of Fig. 3 or Fig. 4. If two D pulses occur between two E pulses (as when changing from A pulses to B pulses), there is an output on line W; if two E pulses occur between two D pulses there is an output on line X. These outputs are sampled, preferably in sequence for the five input signals (Figs. 6 and 7, not shown), and preferably just before each D pulse, and the sampled outputs are fed to the variable counter AS.

Abstract: 1,007,154. Treating yarns. STUDI E BREVETTI APPLICAZIONI TESSILI. Nov. 8, 1961, No. 39948/61. Heading D1D. In a process for continuously treating manmade yarns, particularly yarns of regenerated cellulose in which a plurality of yarns advance through substantially helical paths, taking the yarns in succession, the path of each yarn is included in and partly touches the path of the following yarn, all the yarns are guided to take the same path length through the treatment zone and the same number of turns, and the turns are separated by a distance apart corresponding to the desired pitch of the helix, such separation taking place in a plane perpendicular to the axis of their helical travel. In Fig. 1, the yarns are caused to travel in helical paths along a treatment roller 10 divided into treatment zones by flanges 22.. 27. Feed rollers 11a 11b one for each yarn are provided of smaller diameter than roller 10 and having their axes inclined to the axis of roller 10, each yarn being arranged in turns around its roller 12 and the roller 10. The yarns follow a coincident path on the roller 10 and the path of the innermost yarn between the roller 10 and its feed roller is contained within the corresponding path of the next yarn and so on. Each group of yarns, in travelling to the roller 10 is guided between adjacent teeth of a comb which thus act, to maintain the turns in position, the separation between the yarns corresponding to the desired pitch of the helix on which the yarns travel, and the yarns are caused to pass over the flanges 22. 27 by guides 13. The guides and combs are arranged on a common rod 32 Fig. 5A, the guides being carried by an arc-shaped number 33, and the combs 30m plates 34 each fixed to a sleeve 35 on the rod, the sleeve having a gap 36, so that by rotating the sleeve clockwise the combs can be lowered to inoperative position. A further gap 37 is provided for each guide 13 enabling the latter to be pushed through the rod and the gap 36 into the arc-member 33 where it is held by a washer 38. At the start of an operation, the combs are turned out of operative position, the rollers are laced-up with the yarns arranged in turns at the desired pitch, and the combs turned to operative position to maintain the turns in position. Specification 739,178 is referred to.

Abstract: 1,160,298. Rotary-piston pumps. SPERRY RAND CORP. Sept. 9, 1966 [Sept. 9, 1965], No. 40280/66. Heading F1F. In a rotary-piston pump of the intermittentabutment type, arcuate pistons 24 are lodged in annular grooves 23 within a pair of eccentric annular-plates 21 that abut a rotatable driving- member 22 attached to a driving-shaft 16, the pistons being coupled to pins 25 carrying rollers 27 that engage with radial slots 28 in said driving- member so that when the latter is rotated the pistons travel in the grooves 23 with varying angular velocities and oscillate relative to each other to effect displacement of fluid from an inlet 14 to an outlet 15. The eccentricity of the plates 21 relative to the driving-member 22 is variable so as to regulate the output of the pump, the plates being coupled to each other by axial pins 29, 31 and pivotally supported in a housing 11, 12 by a part-spherical sleeve 35 on the pin 29. The plates 21 are biased into a eccentric position by compression springs 40, Fig. 2, the pin 31 being engaged by a piston 43 that is urged in a direction opposing the action of the spring 40 when pressure is communicated to a bore 44 containing the piston from the outlet 15 through a passage 51 controlled by a spring-loaded valve (46, Fig. 7, not shown), which opens automatically when the said pressure reaches a predetermined value to effect displacement of the piston towards said spring until an equilibrium position for the plates is reached. The plates 21 are pressed against the sides of the driving-member 22 by springs 33, 34 and the pressure of fluid in the outlet 15 acting upon an area of the plates within a recessed or shouldered sealing-ring 56. Fluid trapped in the radially-innermost portion of each of the slots 28 escapes into a space externally of the plates 21 through oblique passages (62, Fig. 4, not shown), and an annular groove 61 in the driving-member whence said fluid flows into an outlet 55<SP>1</SP> by way of a passage 53 and a bearing 54 for the shaft 16 to effect lubrication thereof.

Title: Method and apparatus for heating continuously moving threads or yarns
IPC: D02J13/00
Filed: 1958-12-15
Abstract: Continuously moving threads or yarns of a material which becomes sticky on heating, are heated by being brought into contact with a heated surface the temperature of which is close to the softening point of the material comprising the thread or yarn, and at the start of the process, and before the threads or yarns are brought into contact with the heating surface, the surface is temporarily cooled by means of air to a point <PICT:0843905/IV(a)/1> <PICT:0843905/IV(a)/2> below the softening point of the material and is kept at a reduced temperature until the threads are moving in contact with the surface.  Preferably the threads or yarns are put in continuous motion while out of contact with the heating surface and subsequently a current of cooling air is directed upon the surface to cool it to below the softening point of the material composing the threads or yarns, whereupon the moving threads or yarns are contacted with the surface.  Suitable apparatus comprises a means for the continuous movement of one or more threads or yarns, for example a supply roller 6 and a stretching roller 13, a surface 9, adapted to be heated, thread guides 8 and 15 by means of which a thread or yarn is kept in contact with the surface, and a supply duct 19 for cooling air mounted near the heating surface, the outlet orifices 18 of the duct 19 being arranged to direct air upon the surface.  Means 22 are provided for deflecting air blown past the heater against the side of the heater remote from the ducts.  The air guiding means may be movable and so shaped that they may be moved into a position in which, if necessary together with the air supply ducts, they surround the heater.  Thread guides 10 and 11 may also be provided for holding a moving thread temporarily out of contact with the heating surface. The process may be used in the hot-stretching of yarns.
