Abstract: A substantially continuous method of and apparatus for forming an article suitable for an optical waveguide preform wherein the starting member is continuously removed is disclosed. The preform (26) is formed by providing a starting member or bait (10) and applying the particulate material (20) to the exterior surface of the starting member (10) to form a coating thereon. The coating is longitudinally translated while simultaneously additional particulate material is applied to the coating to form a preform body (26) with the preform body thereafter being longitudinally translated. While longitudinally translated the preform body (26) and applying additional particulate material to the end thereof, the starting member (10) is continuously removed from the preform body (26) leaving a longitudinal aperture (30) remaining in the preform body (26). The particulate material may be applied by one or more burners (18,42) the output of which may be controlled to provide a predetermined desired cross sectional composition variation of the resulting preform body. The so formed preformed body may thereafter be suitably heated, consolidated, and drawn into an optical waveguide.

Date Dec. 10, 1981.A device for dividing a laser beam, e.g. into parallel equidistant beams includes a glass plate with two opposing planer, parallel surfaces. A transmission grating is arranged on one glass surface. A reflecting layer is applied over the grating, and an opening is arranged in the layer at half the length of the plate, for taking the beam, which is to be divided, to and through the grating. The laser wavelength and the grating line density are selected to give total reflection at the free surface of the glass for a beam diffracted at the opening of the grating. By altering the angle of incidence of the beam, the distance between the subdivided beams can be continuously varied within given limits. The device is also utilizable for combining a plurality of separate beams into a single beam. (FIG. 3).

Abstract: Dans le domaine technique de la reproduction sonore au moyen de haut-parleurs electrostatiques a large bande passante on rencontre des problemes dans le circuit d'attaque. Le circuit d'attaque decrit permet d'eliminer les inconvenients que presentent les amplificateurs de l'art anterieur concus specialement, du type a transformateur elevateur, et de rendre les haut-parleurs electrostatiques plus competitifs du point de vue acoustique et economique. Les problemes resolus sont les suivants: obtenir une caracteristique egalisee de passage complementaire a la charge capacitive et a la resistance de radiation changeant radicalement sur toute la gamme audible-signaux sonores d'attaque precis a haute tension, d'un rendement eleve - acoustiquement "plat" (transitions douces d'amplitude, de phase et d'impedance), adaptation appropriee de l'impedance entre les amplificateurs conventionnels possedant une faible impedance et une faible tension d'entree et les haut-parleurs, un prix modere, un poids reduit et un encombrement limite. Le circuit d'attaque utilise deux transformateurs audio specialement concus (T1, T2) en liaison parallele-bilaterale comprenant des reseaux R-C (R2, R3, C2, C3). Afin d'assurer une reponse optimale un transformateur (T1) travaille dans une plage de frequence allant de 30Hz a environ 5kHz, et l'autre transformateur (T2) possedant une impedance d'entree cooperative ajoutee (R1-C1) travaille dans une plage allant de quelques centaines de Hz jusqu'a 20kHz. Une conservation d'energie a resonance aux hautes frequences est utilisee.

Abstract: A rotary fluid pressure device is disclosed of the type utilizing a gerotor gear set (13) and an output shaft assembly (45) including a spool valve (49). The device includes a housing (11) defining inlet and outlet ports (21 and 23). The spool valve and housing cooperate to define a lubrication fluid chamber (59). Torque is transmitted from the gerotor set to the output shaft by a dog-bone shaft (61) having a rearward spline connection (65, 69) to the gerotor, and a forward spline connection (63, 67) to the output shaft. The spool valve defines a pair of annular grooves (71, 73) in communication with the ports and a pair of check valve assemblies (91, 93) to permit flow of lubrication fluid from the lubrication chamber into whichever of the annular grooves is in communication with the outlet port. The resulting lubrication circuit insures a good flow of lubrication through both of the spline connections, in either direction of operation of the device, and further insures that contamination particles are carried from the spline connections to the outlet port without having to pass through severe flow restrictions which can trap such particles.

Abstract: Sandwich hybridization of nucleic acids can be used for the identification of microorganisms or groups of microorganisms present m a sample. The technique can be used to identify, from a single sample containing nucleic acids of the microorganisms or groups of microorganisms to be identified, after first rendering the said nucleic acids single-stranded, all the microorganisms or groups of microorganisms by adding to the sample a pair of nucleic acid reagents for each microorganism or group of microorganisms to be identified, of which pair one nucleic acid reagent is attached to a solid carrier in the single-stranded form and the other contains a completely different nucleic acid fragment from the same microorganism or group of microorganisms, which fragment is labelled with a marker. The nucleic acid fragments of a pair hybridize to a complementary single-stranded nucleic acid from the sample and the hybrid thus formed on the solid carrier is labelled with the marker. Because the labelled nucleic acid reagent does not hybridize directly with the reagent attached to the solid carrier, only those carriers having attached nucleic acid reagents corresponding to nucleic acids in the sample become labelled and the presence of such carrier-bound labels can be measured using established methods.
