Abstract: 887,571. Loud-speakers. VAN HEDEL, A. A. W. J. Nov. 10, 1959, No. 38135/59. Class 40 (4). A loud-speaker assembly comprising two loud-speakers 17, 18 has a reflecting surface 4 in the form of part of an ellipsoid, the centres of radiation of the loud-speakers 17, 18 lying on a line passing through the focus F1 of the ellipse formed by an intersection of the ellipsoid with one of its principal planes, and lying at the foci F 1 <SP>1</SP>, F 2 <SP>1</SP> of the ellipse formed by the intersection with the ellipsoid of the plane perpendicular to the principal axis through F 1 . As shown, the reflecting surface 4 has a base member 5 carrying the loud-speakers, the whole being mounted on a baffle 1, so that the focus F 2  complementary to F 1  lies just outside the aperture 2 in the baffle. The reflected waves tend to converge on a line parallel to F 1 <SP>1</SP>, F  2 <SP>1</SP> through F 2  with lateral inversion of the images of the two speakers. The ellipsoidal portion of the reflector terminates at the plane through F 1 <SP>1</SP>, F 2 <SP>1</SP>, F 2 , the portion between this plane and the baffle being plane. Thus the form of the base member 5 is that of half an ellipse together with a rectangle. A further wall 21 and a further aperture 22 in the baffle board may be provided for sound emerging from the rear of the loudspeakers. The speakers may be of the moving- coil type and may or may not have different frequency characteristics. Specification 719,969 is referred to.

Abstract: 1408068 Insulated wire DES CABLERIES ET TREFILERIES DE COSSONAY SA 17 Aug 1973 [18 Aug 1972] 39095/73 Heading B2E [Also in Divisions Dl and H1] An insulated electrical wire comprises an insulating sheath of plastics material covered with cellulose fibres which are anchored in the sheath. The fibres are of equal length and provide a hydrophobic zone. The coated wire may be made by drawing copper wire 2 off a spool 1, heating it by Joule effect at 4 and passing the heated wire to a dusting device 6 where polyethylene powder 7 is blown through an electrostatically charged mesh 9 on to the hot wire which is earthed at 5. A heating coil 11 melts the plastics powder onto the wire to give a cellular structure (20, Figure 2 not shown) and the molten covered wire passes to a flocking device 12 where cellulose fibres are blown into the molten plastics material and attracted thereto by the electrostatic charge applied from generator 10 to the mesh 15. Air from a liquid air source 18 is blown over the wire to cool it in channel 17 and the wire taken up on spool 3. In an alternative method of manufacture (Figure 4 not shown) the wire is heated initially by a flame (4'), the plastics powder is applied by a vibratory dusting device (6') without the use of an electrostatic charge or blowing, while the fibres are applied by a vibratory device (12') without blowing. This method gives a non-cellular plastics coating. The layer of cellulose fibres swells on absorption of water and thereby prevents water from reaching the inner part of the wire.

Abstract: 1,190,739. Valves. DUNLOP CO. Ltd. 7 Sept., 1967 [9 Sept., 1966], No. 40367/66. Heading F2V. A valve 1 which is adapted to be connected to a fluid-pressure reservoir 4 and to control the flow of fluid to an inflatable article connected at 20 has a valve plug 16 slidable in a chamber 9 with a restricted inlet 15 and an outlet 11 which is normally closed by the plug 16. An unrestricted passage 13 by-passes the restricted inlet to permit fluid-pressure to act on the opposite side of the plug on an area smaller than that on which the fluid-pressure acts in the inlet side of chamber 9. A passage through the plug is closed by a piston 26 spring-loaded and sealingly slidable in a capsule 23 which piston can move away from the end of the plug to vent any excess rise in pressure in reservoir 4. The article is inflated by pulling cable 32 to remove the waisted locking member 28 from behind the capsule 23 so that the latter can move to the right to release the spring- loading on piston 26. Chamber 9 is thus vented to allow the fluid-pressure acting on the opposite side of the plug 16 to move the latter to the left to open the outlet. In a modification the capsule 23 is locked by a roller held in place by a nipple on the end of a release cable. In another embodiment the capsule 23 is in two separate parts respectively abutting under the influence of the contained spring a locking cam and. an abutment on an integral stem of the piston 26 which stem extends through the capsule and has an end abutment to retain the right-hand part of the capsule when the cam is rotated to release the spring-loading on the piston by a cable passing round part of the periphery of and connected to a pulley integral with the cam.
