Title: Electrostatic transducers for converting electrical  signals into ultrasonic signals and vice versa
IPC: G01H11/06
Filed: 1971-11-22
Abstract: 1376335 Capacitor transducers AGENCE NATIONALE DE VALORISATION DE LA RECHERCHE 22 Nov 1971 [20 Nov 1970] 54192/71 Heading H4J A capacitor transducer for ultrasonic use comprises two vibratile plates 1, 2 between which is an electret film 3. The plates 1, 2 are either conductive or have conductive faces. In use an external D.C. voltage 6 is applied between the plates 1, 2 in the reverse sense to that used for permanently prepolarizing the electret film 3 so that the two electrostatic fields created by permanent charge of the film 3 and this external D.C. polarization are additive. The external D.C. voltage is as high as possible bearing in mind that the electrostatic field in film 3 must be less than the breakdown field and that air layers 4 must not ionize. The source 6 is protected from high frequency signals by a choke 10. The plates 1, 2 are connected by a D.C. blocking condenser to a transmitting circuit 8 and a receiving circuit 9. The film 3 is preferably between 3 and 70 microns thick and may be made of polypropylene, polystyrene, polycarbonate, mica, polyethylene terephthalate, phenol formaldehyde resin or "KAPTON" (Trade Mark). Permanent polarization of polypropylene film of 10 microns thickness is obtained by applying 1200 volts between its surfaces for 5 mins. The external polarization, in reverse sense, may be slightly below 400 volts. Transducers having operating frequencies in the range 100 KHz to 200 MHz are obtainable and having wide bandwidths. Applications include long range ultrasonic transmission of acoustic signals and frequency modulated ultrasonic submarine communication.

Title: Pipe coupling
Inventor: HIRSH IVAN YEHUDI
IPC: F16L19/10
Filed: 1968-11-26
Abstract: 1,214,889. Pipe couplings. ENGLISH ELECTRIC CO. Ltd. 25 July, 1969 [26 Nov., 1968], No. 56061/68. Heading F2G. A pipe coupling includes a first body member 11 having an axially disposed divergent internal wall 16, a second body member 12 for mounting on and movement along a pipe 10 to be secured in the coupling, and a deformable ferrule 14 for mounting on the pipe between the two body members, the ferrule having an internally relieved leading end 20 for contacting in use the said internal wall and internally near its leading end one or more annular inwardly-directed sharp cutting edges 22, and, further from the leading end, and inwardly-directed blunt indicating edge 24. Means are provided for drawing the body members together to compress the ferrule axially and thereby compress radially its leading end so that the cutting edge 22 or edges bite into the surface of the pipe 10 and the middle portion of the ferrule bows outwardly and thereafter the indicating edge 24 contacts the pipe to indicate, by way of a substantial rise in the effort required to draw the two body members further together, that the cutting edge is buried in the pipe sufficiently to provide a satisfactory seal of the coupling with the pipe. In a preferred embodiment the body members are screw-threaded and the trailing end 21 of the ferrule is frusto-conical, having a smaller cone angle than the frusto-conical inner wall of member 12. After assembly of the coupling the female body member 12 is screwed on to the male body member 11, the ferrule 14 being pushed along the pipe until its leading edge contacts the internal wall 16 as shown in Fig. 1. As member 12 is further tightened the leading edge 20 of the ferrule is forced inwardly by the convergence of the wall 16, and the wall of the ferrule at the trailing end pivots about the line contact made with the pipe at the inner diameter of the frusto-conical wall 19 until the whole of the bevelled trailing end surface contacts that wall, so that the ferrule bows outwardly and becomes permanently deformed. On further tightening of member 12 the cutting edge 22 contacts the outer surface of a pipe (Fig. 2, not shown) in this position the deformation of the ferrule is such that the second, blunt, edge 24 is lifted clear of the pipe surface. Further tightening of the coupling causes the cutting edge 22 to cut into the surface of the pipe, until further deformation of the ferrule brings the indicating edge 24 into contact with the pipe surface, as shown in Fig. 3. This results in an abrupt increase in the effort required to turn the coupling and thus indicates that a satisfactory seal has been made, and so prevents over tightening. In a second embodiment(Fig. 4, not shown) the ferrule has two cutting edges formed at its leading end, and the pipe 10 does not terminate at the shoulder formed in the male body member 11 but passes through it.

Title: Method of manufacturing carbonaceous fibre

Abstract: 1,214,807. Carbon fibres. ROLLS-ROYCE Ltd. 7 Dec., 1967 [31 Dec., 1966], No. 58490/66. Heading ClA. Carbonaceous fibre is made by pre-oxidizing a polymeric fibre in an oxidizing atmosphere and pyrolysing the fibre in an inert atmosphere to drive off the majority of the fibre constituents except carbon and subjecting the fibre at any stage of the process to a surface removal step in which the surface layer of the fibre is removed, together with flaws therein, whereby a stronger fibre is produced. In an example, polyaccrylonitrile fibre is stretched to 3 times its length while immersed in boiling water, oxidized in air at 227‹ C. for 7 hours, and heated at ¢-‹ C. per minute to 1000‹ C. in an inert atmosphere to give C fibre optionally followed by graphitization at 2750‹ C. Removal of the surface may be effected after heat-treatment by cathodic etching or by chemical treatment in gas, liquid or vapour, or before heat-treatment by dissolution of the surface of the polymer in a solvent such as dimethylformamide or ethylene carbonate. Cathodic etching is performed by suspending the fibre in an inert atmosphere at low pressure and maintaining a large potential difference between the fibres and a plurality of electrodes so that surface removal is effected by bombardment with excited ions. Surface etching in the gas phase may be effected by heat-treatment in air, oxygen, CO 2  or H 2  and in the liquid phase, by a KNO 3  melt, cone. H 2 50 4  + conc. HN0 3 , or metals in which C is soluble, e.g. molten Fe or Ni, K 2 Cr 2 O 7  + H 3 PO 4  at 97-125‹ C., or by electrolysis of certain solutions using the fibres as electrodes.
