Filed: 1968-10-21
Abstract: 1,184,870. Winch drive arrangements. GEARMATIC CO. Ltd. 21 Oct., 1968 [25 March, 1968], No. 49845/68. Heading B8B. [Also in Division F2] The reduction gear drive for a reversible hydraulic winch drum 11 includes a multi-disc brake 21 operable on the annular gear 16 of an epicyclic train 12, 14, 16, the brake which is normally spring applied being hydraulically releasable to free the drum from the drive gear so that a load thereon can be given a controlled or an emergency free fall lowering. The drum 11 is driven by a carrier 13 for planet wheels14 which mesh with a sun wheel 12 on a drive shaft 10 and internal teeth 15 on the gear 16. The brake 21 for the gear 16 comprises discs set between pressure plates 25, 28 which are caused to clamp the discs due to levers 26 being pivoted about points 27 by a piston 30 biased by springs 29, the plates 25, 28 being unclamped when fluid is supplied to a cylinder 31 causing the piston to compress the springs 29. The fluid pressure at the cylinder 31 is controlled by a manual valve which controls the rate of bleed from the hydraulic system, that fluid which doesn't bleed from the said valve passes out of the system through a metering valve 18 driven by external teeth 17 on the annular gear 16. Therefore, with full bleed from the manual valve, the brake 21 is applied and the metering valve is stationary, and with no bleed from the manual valve the brake is fully released and the metering valve bleeds the full hydraulic flow. For the emergency free fall condition, the hydraulic pump is communicated directly to the cylinder 31 for instant brake release, the metering valve being by-passed.

Abstract: 1503996 Pile-drivers VAN KOOTEN BV 5 Dec 1975 [10 Dec 1974] 49935/75 Heading B3H In a method of regulating the supply of fuel per stroke to a diesel pile-driving hammer a measurement of the energy induced in the pile per stroke is made in each of at least two strokes, the fuel supply in each of these strokes is measured and related to the energy induced in the stroke and the fuel supply in a succeeding stroke is adjusted in accordance with the fuel supply in that one of the at least two strokes in which the greater or greatest total energy was induced in the pile. The strain induced in the pile is measured by strain gauges 60, Fig. 13, and converted to stress by a meter 61, the output of which is fed to an integrator 63. A signal 48 from the integrator 63 and a signal 66 corresponding to the quantity of diesel fuel supplied are fed to a computing device 65, in which the values of the signals are compared with those of previous strokes for fixing a programme for the fuel supply adjustment. The calculated output 49 of the device 65 and the measured signal 48 are fed to a comparator 46, which determines the optimum fuel supply adjustment. The output 50 of the comparator is fed to a control member 41a for operating a control slide 43a of an hydraulic cylinder 44a. The piston in the cylinder 44a, Fig. 10, pivots a bell-crank to alter the setting of a stop 33a and hence the volume of a fuel injection pump cylinder or cylinders 9. The items 41a, 43a, 44a, 33a, 7a, may be duplicated, Fig. 6 (not shown), to supply petrol to benzene to injection nozzles (30b), so as additionally either to accelerate or decelerate the rate of combustion of the diesel fuel.

The jets 158 have a piston at their lower end in a pneumatic cylinder, Fig. 13 (not shown). In a modification, Fig. 6 (not shown), the cleaning jets are fixed and the floor of the troughs slopes up towards them. Another modification, Fig. 7 (not shown), has the movable jets with a hopper for scale &c. disposed in front of each. A further modification, Fig. 8 (not shown), has fixed jets blowing the scale &c. through the ends of the troughs into the lower heating zone of the furnace, the burners in this instance being disposed at the furnace discharge end of the troughs. In a final modification, Fig. 10 (not shown), the jets are disposed in niches formed in pairs in the bottom of the troughs and are angled inwardly to intersect on a longitudinal centre line. The collecting hopper is disposed between the last two pairs of jets at the discharge end, the final pair of jets being reversed towards this hopper. An electrical and fluid circuit arrangement, indicated schematically in Fig. 17 (not shown), gives sequential operation of the cleaning jets 158, individual burner adjustment using the thermocouples disposed in the troughs, control of the secondary air valves 228 and control of the hopper doors 154. A number of burners in the furnace end wall, Fig. 1 (not shown), heat the soaking zone and hot gases therefrom travel towards a soaking zone nose defined by a downwardly sloping portion of the soaking zone roof and the end wall of the heating zone. Upper and lower burners are disposed in this end wall and hot gases travel above and below the charge to a flue near the charging end of the furnace. The skid rails, Fig. 1A (not shown), comprise a water-cooled steel pipe with a skid strip welded thereto and otherwise surrounded by a layer of plastic alumina.

Abstract: 1304248 Seismic trace processing MOBIL OIL CORP 23 Oct 1970 [23 Oct 1969] 50471/70 Heading H4D A velocity section of the earth's subsurface is prepared by processing seismic reflection traces to determine which of a plurality of assumed normal moveout (NMO) curves best fit trace-totrace alignments of reflection events and then plotting in numerical form the velocity values associated with the best-fit curves. Fig. 3 is a flow chart for the digital processing of common depth point (CDP) sets of traces, one such set being shown in Fig. 1 as traces S1 to Sn in order of increasing moveout (source-detector offset x). For a particular sample instant T1 of zero-offset trace time T0, a range of acoustic velocities V between limits V1 and V2 is assumed and the NMO time shifts #T (based on these assumed V values) are computed for trace Sn. The trace sample times 22, 32 &c. nearest to the computed #T values are then selected and used to re-calculate the moveout curves (given by the equation at 26 in Fig. 3) and to derive values of the actual velocities. From this basic set of curves, assumed V values for later zerooffset sample times T2 &c., are computed iteratively by substituting different values of T0 in the equation. To avoid this iterative computation producing V values outside the range of velocities expected for the subsurface, a fresh basic set of NMO curves is calculated each twenty-five samples of T0. Having thus established a basic set of assumed NMO curves common to each of several values of T0, respective sums of the trace samples are taken along each curve for a given T0 and the velocity associated with the curve giving the greatest sum is noted. If the sum exceeds a threshold value α the noted velocity is assumed valid and is plotted in numerical form at the appropriate trace time TO/horizontal distance co-ordinates on a seismic section. Continuity of reflections from one CDP set to another is also detected and is indicated by plotting line segments in the section. Further processing envisaged is the application of NMO corrections, stacking of the corrected CDP traces, velocity modelling, migration, mapping, and identification of multiples.

In a ciphering and deciphering apparatus digital data on a first channel is ciphered, and ciphered data on a second channel is deciphered, using a random key generator which is shared by both channels. When a signal on the first channel 1 is to be ciphered it passes via switch COM 1, Fig. 2, to unit CHT where it is ciphered with a key signal from key generator CL. The previous key signal, which relates to channel 2, is stored at MP. Under control of clock HO, the key signal for channel 1 is passed to store MT and the store MP is read out to set the key generator CL to the state it had earlier in respect of channel 2. The channel 1 key signal is now read from MT to MP. Clock HOR controls key generator CL which provides a new channel 2 key signal, so that a ciphered signal on channel 2, selected by switches COM, is deciphered in unit CHT. Clock HO next controls the interchange of key signals among MP, MT and CL, as described above, so that CL is ready to generate a new key signal for ciphering channel 1.

Apparatus for coking coal is combined with steam generating plant. As shown in Figs. 2 and 3 compacted coal 1 having channels 11 therethrough rests on a revolving annular disc 3 supported on a frame 5 which rotates around a circular track 7. A gaseous heat-transferring medium, e.g. from the combustion of solid fuel, oil, gas or blast furnace top gas, is passed from inlets 21 radially outward through the channels 11 in the coal and thence into the channels 23 and 24 from where, after partial combustion with air from the nozzles 25, it passes inwards through the coke in region 26 and through the fresh coal in region 27. From regions 26 and 27 the gases pass through slits 12 in the wall 29 of the firing chamber 4 where they are burnt with air from 14. The hot flue gas then passes upwards, together with flue gas from the burning of a supplementary fuel introduced through passages 19<SP>1</SP>, into the radiation chamber 18 and into the contact heating portion 19 of the steam generating plant. Fig. 1 (not shown) shows a simpler coking plant in which the brick checkerwork, corresponding to the brick checkerwork 28 shown in Figs. 2 and 3, forms radial or tangential slits to allow the gases, which, pass inwards through the channels in the fuel, to flow from the fuel into a central chamber, which serves as a radiant chamber for the steam generating plant, and then into the heating chamber of a tower or horizontal boiler of the steam generating plant.
