Patent GB-1048270-A (GB)
Abstract: 1,048,270. Measuring sound intensity; matching acoustic impedances; microphones. CANADIAN PATENTS & DEVELOPMENT Ltd. Oct. 18, 1963 [Oct. 19, 1962], No. 41213/63. Headings H3U, H4D and H4J. A probe microphone assembly for use in the measurement of sound intensity comprises a probe tube coupled to the microphone via a horn terminated by an acoustic resistance element. Fig. 1 shows the general scheme where the probe tube of length L and uniform crosssectional area S 1  is coupled to the smaller end of an exponential horn of similar area and of length l, the larger end of cross-sectional area S 2  being coupled to a condenser microphone M, which with the coupling cavity has an effective volume V 1 , and to an acoustic resistance R 2 . To prevent the microphone from responding to sounds other than those transmitted by the probe tube the acoustic resistance instead of being left open to the atmosphere is vented into an enclosure V 2  the volume of which is large enough to prevent short-circuiting of the resistance at all significant frequencies. An improved response, however, is achieved by replacing V 2  by an acoustic network comprising an enclosure of volume V 2 a (<V 2 ), Fig. 3, coupled to a much larger enclosure of volume V 2 b via a damped inertance m, the latter forming a Helmholtz resonator which should resonate near the horn cut-off frequency. In a practical embodiment of the invention (Fig. 4) the acoustic resistance is defined by a conical portion 33 in an insert 25 (see also Fig. 5) and an aperture 42 in a cover plate 40 to which the microphone 4 is secured, the distance between 33 and 42 being made adjustable by means of shims 48 when the assembly is clamped by means of screws 45 provided with resilient washers 46. The acoustic resistance is vented into the enclosure, i.e. enclosure V 2 a, defined by the cut-away portions 29 of insert 25 when the latter is clamped inside a cylindrical chamber 20 the flat side 19 of which is provided with an aperture 26 communicating with two relatively smaller apertures 62 (forming the inertance m) communicating with a capacitance member 63 (forming enclosure V 2 b) which may be filled with sound-absorbing material.

Abstract: 1,122,722. Seismic prospecting. MOBIL OIL CORP. 26 Sept., 1966 [27 Sept., 1965], No. 42865/66. Heading H4D. In a method for reducing random noise on seismic data while preserving coherent noise and primary reflections, seismic waves are generated by a source and the resulting seismic reflection signals detected at a plurality of stations spaced substantially equal distances from the source are composited. In the embodiment of Fig. 1, six-fold coverage of each of a plurality of common depth points such as P24 to P27 is provided by firing a shot (or using a dropping weight) successively at shot-points 1 to 8 and recording reflection signals with detector spreads A to H, respectively, each comprising twenty-four detector stations. The recorded traces associated with equal shot-todetector distances are then summed and the summation signals are displayed to provide a seismic record section (Fig. 2, not shown), with summation traces (e.g. 72, the sum of traces recorded at the first detector in the spread for shots at shot-points 5 to 8) arranged side-by-side with separations proportioned to the separations of their associated subsurface reflecting regions. Static and normal movement corrections may or may not be applied to the individual traces before summation, and incremental time-shifts may be applied before summation to correct for any dip of subsurface reflecting regions. It is stated that the composite record provides an indication as to whether such normal movement corrections are in error, and the record may thus provide seismic velocity data for the normal moveout corrections to be applied to traces in the conventional compositing of common-depthpoint traces. In an alternative seismic shooting procedure (Fig. 5) the detectors are arranged in linear or arcuate arrays (112, 114, 116) such that all detectors in a particular array are equi-distant from the shot point (110) and the arrays are spaced along an exploration line through the shot-point, the outputs of all detectors of a particular array being combined. before recording.

Abstract: 1,227,757. The formation of carbon yarn. COURTAULDS Ltd. 13 Aug., 1968 [14 Aug., 1967], No. 37214/67. Heading C1A. [Also in Divisions D1-D2] Yarn is made by forming a suspension of staple carbon fibres in a liquid, depositing the fibres in the form of a tape on an elongated grid by passing the suspension therethrough, forming a continuous yarn from the tape and bonding the fibre together at some stage after formation of the fibre suspension. The carbon fibre suspension can be made by dispersion of the fibres in a turbulent flow of water with the aid of a wetting. agent. The grid can be in the form of a narrow cylinder confined between flanges which are rotatably mounted and partially immersed in the suspension. The liquid phase of the suspension then passes through the grid into the interior of the cylinder and is sucked out through one of the bearings. A baffle can be mounted inside the cylindrical grid, or the cylinder can be internally partitioned so that the suction is restricted to a particular arc of the grid. The binder, e.g. an emulsion or solution of uncured epoxy or polyester resin, can be present in the suspension or can be applied to the formed yarn. The tape can be twisted to form the yarn.
