Title: Method of exploring a medium and its applications in seismic exploration
IPC: G01V1/00
Filed: 1973-05-18
Abstract: 1426943 Wave-energy exploration of a medium SOC NATIONALE DES PETROLES D'AQUITAINE 18 May 1973 [19 May 1972] 23879/73 Heading H4D To locate reflectors in a medium, waves are transmitted into it in the form of long CW signals which do not repeat during the period of transmission and which are produced by several sources whose starting instants are staggered such that respective transmission signals are non-synchronous and more than one source is operative in the time that waves take to travel to and from the furthest reflector of interest, the reflection signal components associated with any one of the sources being identified by crosscorrelating the composite reflection signal with a representation of the transmission signal of that one source. The starting instant intervals and relative initial phases of the sources are chosen to give a high ratio of the amplitudes of the maximum peak and secondary peak of the function which would be obtained by crosscorrelating the combined transmission signal of all the sources with the transmission signal of an individual source, as compared with the analogous ratio for cross-correlation of the composite reflection signal with the transmission signal of the individual source. Embodiments are described for seismic exploration, using amplitude-modulated or frequency-modulated transmission signals, three aligned sources whose signals are the same except for their phase, and one or two rows of receivers aligned parallel to or at right angles to the source line. The use of three sources enables three seismic profiles to be covered simultaneously, and the non-synchronous nature of the source transmissions enables horizontally-travelling surface noise at the receivers to be cancelled by appropriate spacing of the sources and receivers in relation to the noise wave propagation speed and the relative phases of the sources.

Abstract: 337,470. Hartmann, C. W. Aug. 3, 1929. Packeting granular materials in cartons.-In machines for. filling cartons &c. with granular materials, the cartons are received successively from a delivery device common to a number of parallel conveyers to each of which the cartons are delivered and by them carried past a corresponding number of filling devices. Blanks are delivered from a pile 5, Figs. 1 and 2, to a guide 7, from which they are removed by a former 8 on a rotary turret. By the time the former has arrived at position A, the blank has been folded into a tube, at B the flaps at the outer end are gummed by devices 10. The flaps are closed at C and pressed at D. At F the carton drops or is stripped from the former on to a laterally extending support 13, Fig. 3, and is pushed to one side or the other by a plate 12 on a reciprocable rod 14. The cartons are fed to filling devices 3, Fig. 2, by fingers 2 on two parallel conveyers 1 from the positions to which they have been pushed by the plate 12. The conveyers are stationary at the moment at which the empty cartons are aligned beneath the filling devices, and the cartons are raised against the hoppers, this movement being utilized to release the material. After filling, the conveyers feed the cartons to closing, pressing, and delivery apparatus, which may be as described in Specification 337,688, [Class 78 (i), Conveyers &c.]. When the cartons are to be divided into three lines, the member 12 is arranged to move one carton to the right, the next to the left, and to miss the third one, which is carried away through the centre of the machine by a central conveyer. Three filling devices are provided and the various triplicate portions of the apparatus are interconnected so as to operate in synchronism. A number of machines may be arranged side by side, all the corresponding devices being operated by common transverse shafts.

Title: Improved means for regulating turbo blowers and other apparatus for delivering fluid under pressure or suction
IPC: F04D27/02
Filed: 1920-08-24
Abstract: 171,787. Kemp, L. C. Aug. 24, 1920. Regulating or controlling.-A turbo-blower or the like is regulated by the operation of the tur- - bine valve or other speed-control device by a piston subject to static pressure at the place of delivery, and this action is modified by a device acting on the transmission mechanism to obtain close regulation for constant volume of delivery. In the form shown in Fig. 1, the piston C, which is subject to the pressure of delivery, is connected by a rod E and link F to a member carrying the rack K. The lever E is also connected to a pilot valve J, which controls the admission of pressure to a cylinder I. The piston H in this cylinder is attached to the rack K and repeats the movement of the piston C. The rack is engaged by a pinion L, the spindle of which carries a cam N. The cam is cut to the form of the constant-volume curve on a speed-pressure chart and it modifies the transmission to the pinion S, which may operate the speed-control device either directly or through a relay. The actuation may be obtained independently of, or conjointly with, the speedgovernor mechanism. Where an electric motor is used, the roller 0 operates a rheostat. The cam may be so shaped and adjusted axially with respect to the roller 0 that it regulates for any one of a. number of rates of delivery. The subsidiary regulation may be obtained by using a velocitycontrolled device to displace the fulcrum of one of the transmitting-levers. In the modification shown in Fig. 4, the piston H is connected directly to the turbine valve, and by the levers E, E<1> to the pistons C, Z. The piston C is subject to the static pressure of discharge, while the piston Z is under the control of a pilot valve Y operated by the dynamic pressure piston X which is formed as a bell with its edge dipping into mercury. The opposite sides of the enclosing chamber are connected to the static and velocity members of a Pitot tube.

As shown in Fig. 1, the rotary valve n, with central opening o through which the material is discharged, is provided with a crank n<1> connected by a slotted link n<2> to the levers f<2>, g<2> operating the buckets, the change over of the buckets taking place when the valve is closed and being accelerated by the provision of a rolling weight r<1> in a tube r attached to the bucket g; the slot in the link n<2> permits the rotation of the valve through the open position when the buckets are at rest, material being discharged when the buckets are together at the top. The device is rendered airtight by the provision of spring-pressed packing pieces h<1>, m<1> which work over the interior surfaces of the outer casing a, and similar pieces q engage the surface p of the rotary valve; at the upper and lower parts of the buckets, projecting ridges f<3> engage rubber pads g<3>. As shown in Figs. 2 and 5 a sliding plate valve t is employed, which works over machined surfaces u and is connected through springs t<4> to links t<1> pivoted at t<2>. A slow oscillatory motion is imparted to this valve through a link v. The buckets are geared together through quadrants s, and their change-over movement, which is accelerated by the action of a spring attached to the ends of the two quadrants, is effected by the engagement of a lug w on the link t<1> with two projections x<1>, x<2> on a quadrant x connected to the pivot g<1> of the bucket g. In operation, the lug engages the projection x<1> after the valve has closed, effects the change-over of the buckets, and then swings clear of the projection and allows the valve to move over to its extreme position, uncovering the opening e; during the return motion of the valve, the projection x<2> is similarly engaged, the valve again having closed. Valves may be provided at the inlet instead of at the outlet of the casing.
