Title: Improvements in electro-magnetic vibratory devices, such for example as sound reproducing or recording devices
IPC: H04R11/00
Filed: 1929-11-26
Abstract: 346,852. Telephone instruments. WIRELESS MUSIC, Ltd., 29, Charing Cross, London, TROUTON, M., Dadbrook House, Cuddington, Buckinghamshire, CARPENTER, R. E. H., 21, Smithambottom Lane, Purley, Surrey, and DAVEY, F. G. G., Rosslyn House, Rosslyn Hill, Hampstead, London. Nov. 26, 1929, Nos. 36262 and 39918. [Class 40 (iv).] In a sound reproducing or recording instrument, such as a loud speaker, of the kind in which an armature is acted upon by magnetic forces that counterbalance in the central position of the armature, mechanical means of considerable stiffness for centralizing the armature are provided so that, in the absence of the magnetic field, the armature has a relatively high frequency, e.g. not less than 1500 cycles per sec., while this frequency is considerably reduced, preferably to less than one-half, by the reduction in stiffness imparted by the presence of the magnetic field, which has a strong negative stiffness or magnetic instability. In the construction shown the armature 1, 12 is rigidly attached to a cross-bar 13, which is clamped between bars 15, 16 and which, by its torsional and bending stresses, provides the restoring force for the armature and determines the natural frequency of the latter. The armature is polarized and associated with pole-pieces 3, 4 of opposite polarity to that of the armature, the magnetic flux being derived from two horse-shoe magnets, the poles 21, 22 of one only of which are shown. A third pole 24 of the same polarity as the armature is located below the latter, the various magnetic circuits being completed by the elements 13 .. 16, 23 and 17. Speech coils 19, 20 surround a yoke 18 contacting with the pole-pieces 3, 4. With the object of obtaining a magnetic pull on the armature of the requisite strength and one that is substantially proportional to the displacement of the latter, the armature is mainly of a T cross section, the rib portion 12 moving between and in the plane of the polepieces, while the flange portion 1 moves outside this plane. Both portions 1, 12 of the armature taper from the cross-bar 13, the taper of the rib portion 12 being the greater and preferably so designed that, if the armature were tilted sufficiently about its virtual axis, flat contact would be made with one or other of the polepieces 3, 4. The loud-speaker diaphragm is connected to the armature at a point 29 on an armature lug that is spaced from the rod 13 at a greater distance than the line of action of the resultant magnetic force.

IPC: C07C17/20
Filed: 1956-11-27
Abstract: Hexafluoro-1,3-butadiene is prepared by heating 1,2 - dichloro - 1,2 - difluoroethylene in a closed vessel at a temperature in the range 100 DEG  to 400 DEG  C. for a time sufficiently long to form 1,3,4,4 - tetrachloro - 1,2,3,4 - tetrafluorobutene-1, chlorinating this to 1,1,2,3,4,4-hexachloro - 1,2,3,4 - tetrafluorobutane, fluorinating this to 1,2,3,4-tetrachloro-1,1,2,3,4,4-hexafluorobutane and dechlorinating this latter compound to hexafluoro-1,3-butadiene with zinc in the presence of a lower alkanol having less than 6 carbon atoms per molecule.  In the above process an antimony fluorohalide, antimony fluoride and chlorine or hydrofluoric acid in the presence of a vapour phase fluorination catalyst, such as chromium fluoride may be used as fluorinating agents, whilst gaseous chlorine in the presence of actinic light may be used as a chlorinating agent; also the conversion of 1,2,3,4 - tetrachloro - 1,1,2,3,4,4 - hexafluorobutane to hexafluoro-1,3-butadiene is carried out under essentially anhydrous conditions.  An example describes the preparation of hexafluoro - 1,3 - butadiene wherein a mixture of cis- and trans-1,2-dichloro-1,2-difluoroethylenes, boiling at about 22 DEG C., is heated under pressure to form a mixture from which the dimer CFCl=CF-CFCl-CFCl2 is separated by fractional distillation.  The dimer is chlorinated by gaseous chlorine in direct sunlight to form CFCl2-CFCl-CFCl-CFCl2 which is again fractionally distilled and then heated with SbF3Cl2 to form a mixture of fluorinated chlorohydrocarbons C4ClF9, C4Cl2F8, C4Cl3F7, C4Cl4F6, C4Cl5F5.  The C4Cl4F6 fraction is heated with powdered zinc in absolute ethanol when gaseous CF2=CF-CF=CF2 is evolved and condensed.
