Abstract: A fiber optic amplifier is disclosed, comprising a fiber optic, monomode waveguide (20) having a core (64) and cladding (66). A portion (70) of the cladding (66) over a predetermined region is removed and replaced by an active medium (30) capable of absorbing light energy at a first wavelength and emitting light energy at a second wavelength. The active medium (30) is a lasing dye that has an index of refraction adjusted to be slightly less than the index of refraction of the fiber core (64). The amount of cladding (66) removed is adjusted such that a predetermined amount of penetration of the evanescent field from a pump light signal (36) coupled into an end of the fiber (20) penetrates the active medium (30). A probe signal (38) to be amplified causes stimulated emission from the excited dye molecules by penetration of its evanescent field into the dye (30) in the region where the cladding is removed.In the preferred embodiment a recirculating pump (110) is used to circulate dye (30) through a cavity (112) placed over the fiber (20) where the cladding portion (70) is removed. The dye molecules in contact with the surface (72) formed by removal of the cladding (66) are continually changed. A temperature control unit (110) maintains the temperature of the dye (30) such that its index of refraction remains tuned to an amount just less than the index of refraction of the core (64).

Abstract: Process for the continuous or semi-continuous fabrication of propellant powders in which raw nitrocellulose is homogenised and stored under water in large tanks, from which it is fed in a controlled manner to a continuous centrifuge which removes water and alcoholises the nitrocellulose gradually. The alcoholised nitrocellulose is fed continuously to a stage where it is mixed with solvents and additives to form a gel which is compacted and extruded into filaments. Granules are made from the filaments and are transported in small batches to a preliminary drying step which removes that larger part of the solvents, in suitable vessels in a programmed manner. The granules discharged from these vessels are collected, in an inert state, and thereafter the powder is prepared and transported hydraulically to subsequent stages, including boiling and final drying.

Abstract: The industrial truck or vehicle comprises a support body or member supporting an elevatable platform. The support body is supported and guided on both ends by a respective transverse pivot joint of a respective driving module or unit. The width of the support body and the platform is narrower than the width of the two driving units. This narrowing or reduction in width of the industrial vehicle ensures that the complete platform region on both longitudinal sides of the industrial vehicle is manually accessible despite providing good lateral vehicle stability. Furthermore, the torsional elasticity of the support body is increased such that the support body in combination with the transverse pivot joints provide sufficient travel surface adhesion or floor traction of all drive wheels and support or free-running wheels even over irregular or uneven travel surfaces. The industrial vehicle possesses an emergency recovery device so that it can be temporarily driven without auxiliary devices if up to two wheels become blocked. For this purpose the driving units are tilted individually or in combination about the still functional wheels by means of a respective drive spindle until the blocked wheels are free of the floor or ground surface and the industrial vehicle is rendered mobile. The reduction in width of the industrial vehicle and the autonomous capability of recovering from emergencies permits this industrial vehicle to be utilized in flexibly-organized assembly plants, especially in the automotive industry.

Granted: 1992-01-29
Abstract: Heat sealing of wrapper laminates (31, 32) made of foam (102) supported by a porous substrate sheet is improved by coating on the foam-engaging face of the substrate a barrier layer such as polyvinylalcohol to keep the foam (102) when melted from bleeding through the substrate. The support for the foam can alternatively be non-porous film such as polyethylene terephthalate. In a cold sealing embodiment the foam face of supported foam wrappers has a cohesive-nonadhesive layer which can contain improved volatile corrosion inhibitor and/or antistat compositions that do not shorten its shelf life below about six months. One such composition is a mixture of dicyclohexylamine with 2-amino-2-lower-alkyl-propadiol-1,3. Protective colloid such as polyvinylpyrrolidone is preferably also added to improve the compatability of the volatile corrosion inhibiting composition with the rubber latex that provides the cohesive-nonadhesive characteristics. Heat sealing of wrapper can be effected with the help of hot melting shoes (39 and 41).

Abstract: A ski boot (10) which creates a vacuum between the boot and user's foot, ankle and lower calf. The boot includes a rigid shell (12) formed in sections which permit articulation, and padded liners (56) are mounted within the shell. A flexible sheath (64) secured to the shell forms an hermetical seal about the calf of the user. Means are provided for maintaining a partial vacuum within the boot. The partial vacuum causes both contraction of the boot shell and expansion of the foot to establish a close fit of the foot within the boot. The boot provides lateral stiffness while permitting forward flexing, and the close fit permits the user to achieve precise control during skiing.
