Title: Improvements in or relating to methods of manufacturing electro-acoustic transducers
IPC: H04R11/00
Filed: 1967-01-02
Abstract: A method of manufacturing (assembling) an electro-acoustic transducer, e.g. a microphone, is as follows. The diaphragm 2, made of non- magnetic material, e.g. aluminium, is glued at its edges to the support plate 1 of the device. These parts are supported in a jig while the magnet system 5, having a magnetic diaphragm 6 is lowered into the hole in the plate 1. The magnetic diaphragm 2 is then stuck to the diaphragm 5 and the magnet system 5 secured in the hole by means of adhesive 8. The diaphragm 2 may be flat, as in Fig. 1, or conical, Fig. 2 (not shown), in which case a central rigid coupling member is provided, the end of which is secured to the magnetic diaphragm 6.

Title: Multicolor pick change device for weaving machines
IPC: D03D47/38
Filed: 1968-10-23
Abstract: Weft guides 1-4, which descend to the same point 82 to present weft to the weft inserter, are swung about individual pivots 6-9 by a slide 26 carrying arms 22-25, a selected one of which is moved under the tail 18-21 of a weft guide by the dobby or jacquard. The slide is operated by a cam 37 and is locked at the end of its stroke by a pawl (not shown) so that the same weft can be inserted on successive picks without the necessity of re-operating the weft guide the slide is released when a change of weft is indicated. The arms 22-25 are moved under the tails of the weft guides (see Fig. 4) by springs 43 acting on arms 38, when allowed to do so by cams 47, 48 on two camshafts operated by the dobby either camshaft can hold any lever 22-25 clear of its weft guide tail (as shown), and each shaft has two angular positions, thereby producing four combinations which enable one weft guide at a time to be operated. Springs are interposed in the connections from the dobby to the camshafts, so that the dobby can preselect the next setting, which takes effect when the camshafts are unlocked at the completion of a weft insertion. When a semi-open shed type of dobby is used, the connections from it also include an arrangement whereby partial movements followed by a return to the original position have no effect on the camshafts.

Title: Preparation of allylphosphonic acid and esters and salts thereof
IPC: C07F9/40
Filed: 1969-05-12
Abstract: 1,2-Propenyl phosphonic acid or ester or salt thereof is obtained by treating allyl phosphonic acid or ester or salt thereof with a catalyst comprising a transition metal compound either in the presence of a proton-donating solvent or in the presence of an inert (e.g. a non-protondonating) organic solvent and hydrogen (preferably under pressure). The product is obtained as a mixture of the cis and trans isomers which may be separated, e.g. by column chromatography, vapour phase chromatography, or fraction-distillation or -crystallization. The transition metal catalyst may be a compound of Fe, Ni, Co, Ru, Rh, Pd, Os, Ir, Pt, Mo, Mn, or Cr and several suitable compounds are specified. The cis form of the free acid or its salts may be epoxidized to form racemic ( ) (cis-1,2-epoxypropyl) phosphoric acid or salts thereof which have antibiotic properties. The trans compounds when subjected to further treatment with the transiton metal compound catalysts are converted to an equilibrium cis/trans mixture from which the cis isomer can be separated. The epoxidation of the cis-1,2-propenyl phosphonic acid or salt thereof may be effected by reaction with H 2 O 2 in the presence of a neutral tungstic acid salt as catalyst. Diethyl allyl phosphonate is obtained by reacting triethyl phosphite with allyl bromide. Allyl phosphonic acid is obtained by treating di-n-butyl allyl phosphonate with concentrated HCl under reflux and is converted to the sodium salt by treating with sodium bicarbonate in water. Cis-1,2-propenyl phosphonic acid is obtained by treating its diethyl (or other) ester with concentrated HCl under reflux.

Title: X-ray method and apparatus for detecting mislocation of steel reinforcements in green tires
IPC: B60C9/00
Filed: 1974-02-19
Abstract: A plurality of X-ray detectors at precise locations relative to the centerline of the tread-stock region of a green tire, operate to sense location of certain X-ray intensities in the axialwise direction of the tire to detect sidewise mislocation of steel reinforcements such as belts, chafer strips, bead bundles, etc., embedded within the uncured rubber layers of such tire while being subjected to penetrative X-ray irradiation and while being turned about its central axis. A horizontal rotating inspection drum on which such green tire is loosely fit, serves to effect such tire turning, and by use of a stripe marking the threadstock centerline and a stripe-tracking servo mechanism, certain desired centerline-oriented locations of the detectors are preserved automatically in the presence of any widthwise wander of the tire on the rotating inspection drum.

Patent ES-438078-A1 (ES)
Title: Fluid curable compositions containing particulate fillers and composite polymeric materials obtained therefrom
IPC: C08K3/00
Filed: 1975-05-30
Abstract: The mixture contains an organic liquid which is polymerisable to form a solid polymer and whose viscosity at the moulding or forming temperature of the mixture is not more than 5 Pa.s. Dispersed in this liquid by means of a polymeric dispersant are finely divided particles of at least one inorganic filler in a proportion of at least 20 % by volume, if desired up to 90 % by volume, based on the total volume of the mixture. The dispersant keeps the filler particles in the polymerisable liquid in the state of a stable, deflocculated dispersion. The dispersant has in the molecule at least one chain-like component which is solvated by the polymerisable liquid and additionally contains at least one grouping which is capable of association with and attachment to the filler particles. The mixture is prepared by dispersing the particulate inorganic filler in the polymerisable organic liquid in the presence of the polymeric dispersant. Owing to the low viscosity of the mixture, it can be made into complicated shapes simply by casting and then be cured to form corresponding shaped articles composed of a composite multicomponent material in which the particulate inorganic filler is dispersed as a reinforcing material in an organic polymer matrix. Mouldings constructed in this way are obtainable in a simple manner and exhibit improved mechanical properties.

Title: Optical communication cable
IPC: H01B11/00
Filed: 1977-02-24
Abstract: An optical communication cable comprises one or more cores of light-transmitting optical fibers substantially decoupled mechanically from the rest of the cable structure. Surrounding each core is an inner jacket which forms a loose-fittng enveloping structure about the core. Surrounding the inner jacket or plurality of inner jackets is an outer jacket which is reinforced with primary strength members to carry expected tensile loads and to thereby relieve the fibers of the core or cores as cable strength members. The core fibers are also buckled into a slackened state under no-load conditions to allow for stress-free elongation of the core fibers during tensile pulling of the cable. In one embodiment, each core comprises linear arrays of optical fibers packaged in a plurality of ribbon structures which are stacked and helically stranded for further strain-relief. The arrays are specifically configured to permit mass cable splicing.

Title: Electromagnetic radiation reactor combustion chamber
IPC: F24S23/00
Filed: 1977-05-09
Abstract: The energy converter has a housing (11), in which a reaction chamber (13) and a combustion chamber (15) are arranged. Concentrated solar radiation is conducted from a parabolic mirror (23) arranged above the reactor housing through a transparent solar glass (31) into the reaction chamber and there strikes a conical reflector (33) which distributes the radiation in the reaction chamber (13). Hydrogen and chlorine are guided in the molecular state via lines (19, 21) into the reaction chamber, in which the chlorine molecules disassociate to form atomic chlorine as a result of the radiation. Chlorine molecules and hydrogen molecules are, together with oxygen supplied via openings (37), guided into the combustion chamber (15), in which a controlled explosive reaction takes place to form hydrogen chloride. The reaction heat and the reaction pressure can be utilised for driving a turbine or a piston machine, it being possible to heat a medium in a duct (30) in the inside of the reactor. When this energy converter is used, fossil fuels can be forgone. Moreover, a complete cleaning of the combustion products arising is possible.
