Abstract:
A fiber coating stripping apparatus and method for removing an outer coating of an optical fiber including a fiber stripper with a nozzle adapted to spray a stripping medium toward an outer surface of the optical fiber to remove the outer coating, a stripper exhaust including a liquid injection mechanism that provides a liquid to an interior of the stripper exhaust, and a vacuum generator fluidically connected to the stripper exhaust that creates an airflow through the exhaust opening to vacuum the removed outer coating of the optical fiber and to vacuum the liquid provided by the liquid injection mechanism. The liquid is a coolant that cools the removed outer coating and rinses the interior of the stripper exhaust. In one embodiment, the liquid is provided by the liquid injection mechanism with a distribution ring having a plurality of spray openings.

Abstract:
A method of film fabrication is taught that uses a coating and drying apparatus to fabricate resin films suitable for optical applications. In particular, polyvinyl butyral films are prepared by simultaneous application of multiple liquid layers to a moving carrier substrate. After solvent removal, the polyvinyl butyral films are peeled from the sacrificial carrier substrate. Polyvinyl butyral films prepared by the current invention exhibit good clarity and low birefringence.
Abstract:
An automated dispensing system and method for dispensing a viscous liquid material along an imperfect dispensing path. In a first scan, a scanning apparatus determines a dispensing path. A dispensing apparatus dispenses the viscous liquid material along the dispensing path. In a second scan, the scanning apparatus measures a dimension of the dispensed material. Object not meeting an acceptable liquid height are rejected.

Abstract:
Methods and apparatus are disclosed for coating endoprostheses. The methods use distributive forces such as centrifugal force or vibration to distribute a bioactive liquid over the surface of the endoprosthesis. In some embodiments, the endoprosthesis is elongated along the longitudinal axis, and is substantially tubular, such as a stent. In other embodiments, the force is applied by rotating the endoprosthesis at speeds between 100-100,000 RPM, or by vibrating it at frequencies between about 10 Hz and about 200,000 Hz. The invention also includes a device for providing a predictable coating on the surface of an endoprosthesis, which includes means for applying bioactive liquid to the endoprosthesis, and means for applying centrifugal force or vibration to distribute the bioactive liquid. The invention also includes endoprostheses that have been subjected to centrifugal force to distribute a bioactive liquid coating layer.
Abstract:
A process for treating a yarn and/or a fabric to form fine inorganic particulate material in the intra-yarn pores and/or on the surface of the fibers constituting the yarn or fabric, which would substantially maintain fabric reflectance after repeated wash/wear cycles without affecting the desired characteristics of air permeability. The inorganic particles are preferably formed by reacting in an aqueous medium a first reagent selected from mineral and organic acids and a second reagent selected from alkali or alkaline earth metal salts with inorganic anions. The invention also relates to a treatment product composition directed to provide instant inorganic deposits in the yarn or fiber surface.
Abstract:
The invention is a method, and its accompanying apparatus, for charging and discharging short-cycle and/or coating presses with layered pressing material. In order to reduce the charging and discharging times, the method entails inserting a first transport device, or charging device, having a plurality of clamping devices into a charging region and inserting a second transport device having a plurality of suction devices into a pressing chamber, wherein the first and second transport devices are inserted transverse to a longitudinal central axis from a pair of supply axes to a pair of charging and discharging axes. The pressing material is clamped in the charging region and a plate is accepted in the pressing chamber; the first transport device is then moved into the pressing chamber and the second transport devices into a discharging region. The pressing material is then deposited onto a lower heating plate and the first transport device is removed from the pressing chamber and the plate is deposited in the discharging region. Next, the first transport device is withdrawn from the pressing chamber and the second transport device is withdrawn from the discharging region. The first and second transport devices are withdrawn in a direction transverse to the longitudinal central axis from the pair of charging and discharging axes to the pair of supply axes. Last, the transport devices are returned to an original position for a new cycle.
