Abstract: 625,291. Microphones. BRITISH THOMSON-HOUSTON CO., Ltd., and BOCOCK, W. A. Nov. 7, 1946, No. 33140. [Class 40 (iv)] A ribbon-type microphone having laminated polepieces 1 and 2 in which are ventilating passages 17 permitting the free circulation of air around the ribbons 3<SP>1</SP>, 3<SP>11</SP> responds more to sound waves incident upon the ribbon from a direction normal to the surface thereof than from the direction parallel to the ribbon. The microphone consists of two ribbons 3<SP>1</SP>, 3<SP>11</SP>, the lower of which is made responsive to pressure sound waves by closing the end of an elongated damping passage 20, 21, clamped at their upper and lower extremities and situated in the gap between the parallel faces of two pairs of polepieces 1 and 2 bolted to the permanent magnet 8. The laminations A, B, C, D of the polepieces are of different shapes and thicknesses, the thickness of C being equal to the thickness of four D laminations, thus providing, when assembled as shown in Figs. 1 and 3, air passages from the front to the back of the pole-pieces in the proximity of the ribbons bounded by the edges of the C and D laminations and above and below by either A or B laminations.

Title: Improvements in condenser microphones
IPC: H04R19/00
Filed: 1928-11-14
Abstract: 324,152. Voigt, P. G. A. H. Nov. 14, 1928. Condenser telephones. - A condenser microphone, having one or more electrodes of thin metal foil or similar conductor and a dielectric primarily of air or other gas, is so dimensioned that its greatest horizontal dimension is not greater than half a wavelength of the highest note it is desired to pick up at an efficiency exceeding 70 per cent. Such an arrangement is stated to avoid excessive reflection or phase difference .effects. The construction shown comprises a core 2 of elliptical, streamline, circular or other curved form which is either a conductor or covered with a layer of foil. The distance 3, Fig. 2, is preferably not greater than 2.5 cms. The core 2 is surrounded by a moving foil 4, a gas layer 5, with or without extra insulating material, such' as silk, gutta percha &c., serving as the dielectric. The foil 4 is surrounded by a thin film 6 of rubber, gutta percha &c., the intervening air space being dried by means of calcium chloride 8 in a tube 9 which may be of glass or polished metal and is coilnected to the air layer by the passage 10. The foil 4 is preferably fixed air tight at its edges, the connections being brought out at the plug 11. The whole device is surrounded by gauze 1. The length of the microphone may be considerable compared with the dimension 3 e.g. 10 cms. It should not, however, be so great that sounds not coming from a plane at right angles thereto reach one end appreciably before the other so as to produce phase difference effects.

Patent GB-335567-A (GB)
Abstract: 335,567. Imperial Chemical Industries, Ltd., and Saunders, K. H. March 26, 1929. Chemical processes; mercaptobenzothiazole.- Reactions are carried out continuously in the liquid phase under increased pressure by introducing the liquid or liquids under treatment into a reaction chamber whence on completion of the reaction the liquid overflows into a second chamber disposed in the reaction chamber and is drawn off. The mercaptobenzothiazole is prepared by introducing a solution of sulphur in carbon disulphide mixed with aniline oil into a reaction vessel heated to 200-275‹ C. and under pressure, and allowing the mixture on completion of the reaction to overflow into a second chamber disposed in the reaction chamber, whence it is drawn off. Referring to the diagram equal volumes of a saturated solution of sulphur in carbon disulphide and aniline are pumped through the tubes E and D to mix in tube F and enter the pressure-sustaining vessel A, heated to 200- 275‹ at G. The reaction is complete by the time the mixture rises to the top of the tube C into which it then overflows and is withdrawn through the valve I. The pressure is observed by the gauge J and regulated by the valve K. The valve L may be used to empty and clean the annulus. The preparation of ethylaniline and p-nitraniline according to the present process is also mentioned. Specification 329,260, [Class 1 (i), Chemical processes &c.], is referred to.

Abstract: 1341926 Compositions containing polyphenylene oxide and polystyrenes GENERAL ELECTRIC CO 16 July 1971 [19 Aug 1970] 33635/71 Headings C3R and C3P A thermoplastic composition comprises (a) from 1À0% to 99% by weight of an amorphous or partially crystalline polyphenylene oxide having from 0 to 75% of the crystallinity it would have if obtained by precipitation from solution by addition of a non-solvent liquid to the solution, and (b) from 99% to 1À0% by weight of a styrene resin having at least 25% of the polymer units derived from a compound of formula where R is hydrogen, alkyl or halogen, Z is alkyl, chlorine or vinyl and p is 0 to 5. The amorphous or partially crystalline polyphenylene oxide may be obtained by precipitation by adding a solution of the polymer to a non-solvent liquid, by allowing a solution of the polymer in methylene chloride to stand until precipitation is complete, or by heating the polymer above the crystal melt temperature until the crystallinity is reduced and then rapidly cooling. In Examples the crystallinity of poly-(2,6-dimethyl-1, 4- phenylene)-oxide is reduced by precipitation by adding toluene solutions of the polymer to methanol and by allowing a solution in methylene chloride to stand, and blends are prepared with high impact polystyrenes, some of which are rubber modified. Uses.-Mouldings, sheets, films, rods, tapes, electrical insulators, encapsulating material and coatings.

Title: Alkali metal organo-trifluoroborates and their preparation
IPC: C07F5/02
Filed: 1963-08-27
Abstract: The invention comprises the vinyltrifluoroborates and methyltrifluoroborates of potassium, rubidium and caesium.  The novel compounds may be made by contacting vinyl- or methyldifluoroborane with a solution of potassium, rubidium or caesium fluoride at a temperature at which the solution is in the liquid phase but not above 30 DEG C. On completion of the reaction, the product may be dehydrated at a temperature not above 30 DEG C. and the desired product separated by solvent extraction using, for example, acetonitrile or other alkyl nitriles.  Preferably air is excluded during the reaction and the reaction temperature may be from -15 DEG to +10 DEG C.  Purified vinyldifluoroborane and methyldifluoroborane may be obtained by heating the corresponding salts described above. For example, potassium vinyl trifluoroborate may be heated at 250 DEG -300 DEG C. to yield vinyl difluoroborane and potassium methyltrifluoroborate yields methyl difluoroborane on heating to 275-300 DEG C.

Member 12 is yieldingly mounted on platform 10 by spring 18 (not shown) acting between a collar on projection 16 of member 12 and platform 10 and is held against forward motion by bolt 22. Member 12 has convex side walls and a rounded rear end 14. Member 30 is U-shaped the inner surface of arms 32 being concave to co-operate with the side walls of member 12. Member 30 is urged towards member 12 by handle 42 and pivoted links 36, 44, the thrust being delivered by a head 52 in a recess 50. A thermostatically-operated heating coil 24 is placed in a cavity 26 of member 12. A shoe W is placed over member 12. Member 30 is urged against the upper and member 12 whence the upper is pinched. As the force on member 30 increases, member 12 rises from platform 10 against the action of spring 18 (not shown), member 30 thus smoothing the upper over member 12. The shoe may be held above platform 10 by an adjustable spring support 60 which is forced into its retracted position on the movement of member 30 over it and by an adjustable shelf 74. The top edge of the upper round the instep region may be rounded by rubbing the edge in a groove 84 formed in the forward end 82 of heated member 12.
