Title: Improvements in and relating to the manufacture of coarse filaments
IPC: B29C48/29
Filed: 1941-08-01
Abstract: 550,991. Artificial filaments, bristles, &c. DU PONT DE NEMOURS & CO., E. 1. Aug. 1, 1941, No. 9804. Convention date, Aug. 2, 1940. [Class 2 (ii)] Coarse filaments, e.g. of at least 0.01 inch diameter are obtained from a synthetic linear condensation polymer by melting the polymer while blanketed with an inert gas heavier than air, such as carbon dioxide, at a pressure not substantially greater than atmospheric pressure, introducing the molten polymer into a screwpump having a capacity at its intake end at least four times greater than its capacity at its discharge end and then delivering the molten polymer under pressure to a spinneret through which it is extruded. The process is applicable to the production of monofilaments for bristles, sutures, fish-line leaders, racquet strings and the like. The melted polymer may be forced through the spinneret either by the pressure developed in the screw-pump or . by auxiliary pumping means interposed between the screwpump and the spinneret. The filament should be rapidly cooled as it is extruded and this is preferably effected by bringing it into contact with water: As shown, synthetic linear polymer is-melted in a heated chamber 11, provided with a cover 12 with port 13. Banks of tubes 14 carry a heating fluid for melting the polymer. Chamber 11 is provided with a jacket 15 through which heating fluid is circulated. Carbon dioxide or other blanketing gas enters chamber 11 through pipe 16 and leaves by pipe 17. The bottom of the chamber communicates with the casing 19 of the screw-pump. The interior wall of casing 19 is accurately cylindrical. Within it rotates the screw 24 which is rotated by a chain and pulley or sprocket. At the intake end, the screw 24 carries a double-lead flute 27 which terminates in a circumferential groove 28. From this point to the discharge end of the pump, the screw 24 carries a single-lead flute of a capacity substantially less than that of the double-lead flute 27. The discharge end of the pump communicates with spinneret 30 through which the polymer is extruded to form filaments. The total length of the screw may be about 15 inches, the depth of the flute may be 0.05-0.15 inches, and the diameter of the crew may be 1-2 inches. The width of the flute is preferably between one-tenth and one-third of the diameter of the screw. The polymer may be polyhexamethylene adipamide. It may contain plasticizers, dyes, pigments, delustrants, antioxidants or resins. Specifications 461,236, 461,237 and 535,186 are referred to.

IPC: H04B10/291
Filed: 1996-08-15
Abstract: PCT No. PCT/GB92/01579 Sec. 371 Date Apr. 8, 1994 Sec. 102(e) Date Apr. 8, 1994 PCT Filed Aug. 28, 1992 PCT Pub. No. WO93/05596 PCT Pub. Date Mar. 18, 1993.An optical transmission system including an interferometer and a source of optical signals. The interferometer comprises a four-pod optical coupler having first and second input ports and first and second output pods, a silica optical fiber coupling the first and second output pods which exhibits the Kerr optical non-linearity, and an erbium fiber optical amplifier situated asymmetrically between the output ports. The source of optical signals is coupled to the first input port of the interferometer. The system is operated in a regime in which the optical signals saturate the amplifier thereby suppressing any oscillatory output, and their power is sufficient to switch an input signal coupled to the first input pod to the second input pod. This provides pulse shaping and amplification characteristics which are relatively insensitive to the input power of the optical signals from the optical source.

Title: Method and assay for detecting concentration of cyclosporines
Inventor: FISCHER GUNTER
IPC: C12Q1/37
Filed: 1989-09-06
Abstract: The invention relates to a method and an assay for determining the concentration of cyclosporin and its biologically active derivatives. The aim of the invention is to provide a straightforward method for determining the concentration of cyclosporins in biological materials. The measurement of the concentration of cyclosporins is important for monitoring a therapy in patients treated with medicaments which have cyclosporins as active drugs. The amount of cyclosporins in blood serum or plasma can be measured on the basis of the inhibition of peptidyl-prolyl cis-trans-isomerase by cyclosporins. The activity of this enzyme in the plasma can be determined by methods known per se. The method according to the invention quantifies with high accuracy the concentration of biologically active cyclosporins in the blood and is particularly suitable for monitoring therapy with these medicaments.
