Abstract: 454,966. Closing flexible receptacles. BUTLER, W. J., 24, The Fairway, Bickley, and CAMPBELL CONVEYORS, Ltd., Bromley Hill, Bromley, both in Kent. April 12, 1935, No. 11365. [Class 94 (i)] Apparatus for closing paper and like cartons by means of a metallic clip comprises a pair of dies of which one is adapted to be moved relatively to the other and is given successive movements, the first folding a portion of the clip and the carton end, and the second completing the folding and compressing the folded portion and the rest of the clip. The container 1 is placed on a platform 22 mounted on links 24 urged upwardly by a spring 23. A metal clip 2, having one leg longer than the other is placed on the collapsed mouth of the container and the short leg is bent down by hand into the position shown in Fig. 7. The spring 23 elevates the container until the clip is positioned by a stop 6 and the mouth of the container is between dies 3, 4. A handle is turned to cause the rotation of a cam 10, Fig. 3, engaging a roller 9 on a block 7 pivoted at 8 and causes the die 3, resiliently mounted thereon, to advance into the position shown in broken lines in Fig. 8. The die 4 is mounted to slide on a plate 5, and recedes to the position shown against the action of a spring 11. Studs 15 engage slots 17, into which they are sprung by the action of springs 16, and lock the die 4 in the withdrawn position. The continued rotation of the cam 10 allows the die to return to the position shown in Fig. 8 in full lines and to advance again to the position shown in Fig. 9, doubling over and pressing the clip and the top of the receptacle. The extensions of the cam 10 are made of different breadths, and the broader extension engages a boss 19 on a pivoted arm 20 and forces the studs 15 out of the slots 17 so that the spring 11 can move the die 4 back to its initial position for the beginning of a fresh cycle.

Abstract: 1,141,125. Automatic smoke density control. ROLLS-ROYCE Ltd. May 5, 1967 [March 10, 1967], No.11492/67. Heading G3R. [Also in Division G1] A photo-electric smoke detector is used to measure the density of smoke in the exhaust gases of a gas turbine engine. A sample of exhaust gases is fed through an internally blackened sample chamber 1, through which light from source 5 is directed to an infrared sensitive photo-cell 8. The radiation is chopped by a rotating sector-vaned chopper 6. The detector output is amplified at 9 and 10 and indicated on meter 11, which may be calibrated, using a wire 12 of known diameter, in arbitrary units of known equivalence to smoke density. The detector circuitry is detailed in Figs. 2 and 3 (not shown). A double triode connected as a longtailed pair is used for the pre-amplifier 9 and a double triode used as a push pull amplifier 10. The amplifier output is rectified and applied to a bridge circuit, comprising two halves of a double triode and resistors in the triode cathode circuits, the microammeter 11 being connected across the bridge. Sensitivity and meter range are adjustable. The sample of exhaust gases may be obtained from an engine under test when it is obtained from the jet pipe, a silencer or detuner, or from the jet pipe of an engine actually installed on the aircraft. The detector output can be used to control fuel-air ratio in the engine or the supply of a smoke-reducing additive to the exhaust gases.

Title: Determination of response and passband of seismic data gathering  system
IPC: G01V1/36
Filed: 1972-03-15
Abstract: 1349496 Seismic signal processing MOBIL OIL CORP 15 March 1972 [23 March 1971] 11994/72 Heading H4D A measure of the efficiency of a given seismic source receiver spread configuration in attenuating multiple reflections is obtained by processing traces recorded using the spread. In the illustrated embodiment (Fig. 6) values of time TMC and velocity VCR of a travel time/ velocity curve to be used for moveout (NMO) corrections and stacking of a common depth point (CDP) set of traces are read in at 44. For a time-window of this curve, limits of uncertainty of the associated velocity value are set to define at 51 a velocity range for this window. At 52, trace portions relating to refraction effects are rejected and the effective traces to be used for stacking are determined. At 46 a wavelet 20 (Fig. 1) in the time-window on the effective traces is stacked in phase, using the correct velocity, to give a reference power/time response 23, and is then successively stacked using velocities with various assigned percentage errors to obtain for each velocity error a respective degraded power/time response such as 25. The ratio of the latter response to the reference response is computed to give a "relative response". By computing values of relative response for one particular velocity error but for other time-windows, contour lines linking points of equal relative response can be drawn on a map having co-ordinates of time and velocity (Fig. 2, not shown). Similar, respective maps can be drawn for other velocity errors. If it is known that, at a given record time, the velocity for multiples differs from the velocity for primary reflections by, say, 6% then by examining the relative response map associated with a 6% velocity error the relative response for that record time can be found. If the relative response is high, e.g. 75%, it is known that multiples will stack with 75% of the power of the primaries and hence re-designing the spread configuration may be necessary to attenuate the multiples satisfactorily. The relative response for one particular time-window may also be plotted as a function of velocity error to establish the velocity passband of the spread configuration, i.e. the velocity range over which the relative response is above 70%. Successive values of half the bandwidth, DV, are computed for respective successive time-windows. These values are used at 55, as a guide to velocity increments used in a velocity search to determine the correct velocity needed for obtaining the reference response 23 and for deriving at 56 NMO corrections to be used subsequently. The above procedure is repeated for other CDP sets of traces.
