Patent GB-1457153-A (GB)
Title: Method of seismic survexing by extracting and displaying seismic  properties
IPC: G01V1/28
Filed: 1974-06-10
Abstract: 1457153 Seismic signal processing GEOSOURCE Inc 10 June 1974 25686/74 Heading G1G A multi-trace seismic section is processed by dividing it with notional guidelines into horizontal bands corresponding to different depth zones in the earth, establishing on a chart respective reference axes corresponding to the guidelines, and plottting about each such reference axis points corresponding to values of a lithologically-indicative parameter deduced from the trace data in a respective zone bounded by the guideline associated with the reference axis. The Fig. 1 embodiment provides at 20 a digital record of surveyed strata 10. The record is optionally subjected to conventional processing at 22 then plotted as a seismic section at 26. Guidelines intersecting the record traces, Fig. 2, are selected; e.g. geological horizons T1-T4 or isotime lines at À5 second intervals (record time). For each trace, respective zones (i.e. time-gates) above, below or embracing each guideline are defined. Values of a seismic property relating to particular zones are computed from the trace data and plotted about reference axes respectively associated with the zones. In the example shown, Fig. 3, these axes are midway between adjacent guidelines, e.g. at (T1 + T2)/2. Respective values computed for traces a 1 -a 11  for the zone T1-T2 are plotted above the first reference axis to give an envelope 28. Other envelopes are similarly plotted above the axes of zones T2-T3, T3-T4 and so on. For trace a 1  the computed value for zone T1-T2 is divided by that for zone T2-T3 and the ratio is plotted below the axis of zone T1- T2. Ratios for the other traces are similarly plotted to give envelope 30. Other envelopes below the other axes are similarly plotted. It is stated that symmetry of the envelopes such as 28, 30 about their reference axis is indicative of lateral changes in the strata. For comparison with the seismic section or with other computed seismic properties, the plotted envelopes may be produced as a transparent over-lay. The absolute difference between, rather than the ratio of, the adjacent zone values may be plotted to give the envelopes. Examples of the seismic property computed are: (a) seismic wave energy or amplitude, averaged over a zone and possibly frequency-band-limited or at a specific frequency, (b) the dominant seismic frequency, (c) the averaged energy, possibly band-limited, in the amplitude/frequency spectrum, (d) the energyweighted average frequency of the spectrum, (e) the ratio of energies in different frequency bands of the spectrum, and (f) the seismic RMS or average or interval velocity. Analogue or digital implementation of the invention is envisaged.

Title: Improvements in or relating to aeroplanes
IPC: B64C35/00
Filed: 1928-09-07
Abstract: 308,248. Vought, C. M., (Assignee of Watter, M.). March 20, 1928, [Convention date]. Land wheels, runners, and skids; floats.-An amphibian aeroplane with a floating and hydroplaning body has retractable landing gear attached to the underside of the rigid floating and hydroplaning body at a position remote from the chines in the non-retracted position. By dismounting the landing gear, the machine is converted into an ordinary hydroaeroplane. In one form of the invention shown in Figs. 2, 2a, and 5, pairs of struts 8 are mounted at each side of the machine and pivoted at 8<1> above the chines 9. The struts, which may be welded together to form V-shaped pairs pivoted at 7 the apex of the V. A shock absorbing element 60 may be incorporated. The wheel axles 6 are also at one end pivoted at 7 the other end being pivoted at 10<1> to a link 13 which is screw threaded at 13<1> to engage the internal thread of a barrel 12. The barrel is connected by a universal joint 15 with a trunnion 14 rotatable by chain and sprocket gearing 16, 17 from a hand wheel 18. In the operation for raising the wheels the barrel 12, link 13 and axle 6 move together until the barrel is parallel to the bottom of the boat whereupon a cam surface 25 on the link 13 engages a corresponding surface 24 on a body 20 carried by the boat. The body 20 has a slot 22 and a larger chamber 21. The engagement of the cam surfaces leads the link 13 into the chamber 21, the slot being too narrow for the link 13 but of sufficient size to enable the axle 6 to pass freely and break joint by pivoting about the pivot 10<1>. The link 13 meanwhile moves longitudinally through the chamber 21 but is prevented from falling by the narrowness of the slot. In a modification a windless 51 and cable as shown in Fig. 10 serve to move slide blocks 41 along a runway 42 until engaged by a locking device 45. The inner ends of wheel axles 6, link 13 and barrels 12 are housed behind a step to decrease water resistance. In Fig. 9 is shown a housing for this purpose consisting of two bosses 30 between which is a recess 29, the V bottom of the boat being curved to gradually merge into the bosses. In another construction a single recess in the bottom provides the housing. Skids or other retractable landing gear may be employed.

Title: Improvements in and relating to internal combustion engines
IPC: F01L1/344
Filed: 1938-08-26
Abstract: 518,581. Fluid-pressure servomotor-control systems. PORSCHE, F. Aug. 26, 1938, No. 25085. Convention date, Sept. 18, 1937. [Class 135] [Also in group XXIV] The valve timing of an internal combustion engine is varied by altering the relative positions of two parts of the valve control shaft by means of a hydraulic or pneumatic motor controlled directly or indirectly in accordance with the speed of the engine and the position of the engine throttle valve. In the arrangement shown in Fig. 2 a double-acting annular piston 45 is connected by a ball-bearing 44 with a coupling member 13 having a steep pitched screw-threaded engagement with a shaft connected by bevel wheels 8, 9 with the crank shaft 7 and connected by vertical splines with a bevel wheel 11 meshing with a bevel wheel 12 on the valve timing shaft 6. A control valve 59 is influenced by the vacuum in the intake manifold 74, the latter raising a spring-loaded piston 71 connected to the control valve by levers 64, 61 of which the former 64 has an adjustable fulcrum 67 whilst the pivotal connection 63 between the levers moves between adjustable stops 65, 66. The control valve has follow-up mechanism comprising the lever 61 and a rod 62 connected to the coupling at 70. The feed pump has a bye-pass relief valve 22. In a modification the coupling is actuated by a single-acting spring loaded piston acting through a lever and under the control of a governor pump, the suction and delivery sides of the pump being connected through a bye-pass passage controlled by a throttle valve linked to the accelerator pedal. The Specification as open to inspection under Sect. 91 comprises also a modification in which the engine lubricating pump is connected with a power cylinder, the piston of which actuates the coupling. A bye-pass conduit connecting the suction and delivery sides of the pump is fitted with a slide valve controlled by an enginedriven centrifugal governor acting through a lever. The arrangement is such that the timing is advanced as the engine speed increases and the characteristic of the governor may be such as to produce first a rapid advance followed by a more gradual advance as the speed increases. The centrifugal governor may be replaced by a governor pump or by an electric generator. This subject-matter does not appear in the Specification as accepted.
