Title: Nonwoven fabric, wiping cloth made of the same and their production
Inventor: MINETA YOSHIHIKO
IPC: D04H3/153
Filed: 1995-03-27
Abstract: PURPOSE: To obtain nonwoven fabric having excellent shape stability and stain removing properties, suitably usable as a wiping cloth for lens for glasses. CONSTITUTION: Conjugate filament 1 is subjected to melt spinning. The filament 1 comprises a core component and plural shell components bonded to the outer peripheral part of the core component. Either the core component or the shell components have a lower melting point. The filament 1 is accumulated to form a yarn web 3, which is partially heated and pressurized to provide a great number of first fused zones in which the web is fused between the filaments 1. Then the web is subjected to filament splitting treatment and separated into the core component and the shell components of the filament 1 in the first fused zones to form ultrafine filaments composed of the shell components.  A filament fleece 9 comprising the formed ultrafine filaments is partially heated and pressurized to give a great number of second fused zones in which the fleece is fused between the core components and the ultrafine filaments. In this way, nonwoven fabric suitable as a wiping cloth is obtained.

Title: Welding fluoropolymer pipe and pipe joint
Inventor: OSGAR MICHAEL L
IPC: B29C65/20
Filed: 1985-05-01
Abstract: The present invention teaches a method of producing butt welds between pipes or ducts of fluoropolymers, which are extremely chemically inert and which have continuous service temperatures in the range of 300 to 500 DEG F (149 to 260 DEG C) or more, by simultaneously applying infrared or radiant heat to the ends of the pipes or fittings to be welded but without touching the ends being radiated. The radiant heat is derived from a flat faced electric quartz infrared heater which has a surface temperature in excess of 1600 DEG F (871 DEG C) and which is maintained for fifteen to forty-five seconds at a spacing of approximately one-fourth to one-half of an inch (6.35 to 12.7 mm) from the end face of the duct. The time varies with the size of the pipe being welded; and the heater to pipe spacing may vary widely, from 0.125 inch (3.175 mm) to as much as 2.0 inches (50.8 mm).

Abstract: PURPOSE:To control the eccentricity of the roll to the minimum value correspondingly to the variation of the rolling condition, by controlling the position of the backup roll while always comparing the backup roll's position of the memorized minimum amplitude with its present position during the rolling work. CONSTITUTION:In the roll position memory circuit 13, the load variation for every one turn of the roll 1 is detected, and this value is compared with the value of the former one turn and the smaller value is kept in; this is repeated and the positional relation between the upper and lower backup rolls 2, 4, showing the minimum value is memorized, and the backup rolls 2, 4, are set to the position at which the roll's load variation is minimum. Under this condition, the rolling work is started. After starting the rolling work, the detection of the minimum value of the load variation of the roll is not performed; during the rolling work, the driving motors 5, 6, are controlled by the control circuit 16, and the roll position is always kept at the position memorized by the roll position memory circuit 13.

Abstract: PURPOSE:To obtain a lightweight fiber reinforced plastic (FRP) product which has excellent high-impact property and at the same time the surface of which has high gloss by a structure wherein the surface of a glass fiber reinforced synthetic resin base material is covered by an inorganic coating layer. CONSTITUTION:In organic coating is applied on the surface of a mold and, after that, heated and cooled so as to harden it. Glass fibers and thermosetting resin liquid are laminated onto the formed inorganic coating layer and then heated in order to set the thermosetting resin and finally the resultant product is released from the mold. At this time, the molding of resin is performed by hand lay-up molding method or by pressing method in the state that silane coupling agent is added to stock resin or after the silane coupling agent is applied on the surface of the formed inorganic coating layer in order to fit well the inorganic coating layer and the FRP layer to each other. As a result, because the base material is of FRP, a product is light in weight and excellent in high-impact property. In addition, because the inorganic coating is made by mixing powdered solids such as hardener, filler, pigment and the like with water soluble alkali metal silicate-based solution, the obtained product is excellent in hardness and gloss and has high resistances to chemicals and to hot water.
