摘要:
The present invention is directed to chitosan-derivative compounds and structures, methods of making chitosan-derivative compounds and methods for controlling, inhibiting and enhancing microbial populations in a variety of environments. The present invention is also directed to the control, inhibition and enhancement of microbial populations in animals, particularly humans. The microbial populations include bacteria, viruses and other pathogens where control of microbial populations are a necessity. The chitosan-derivative compounds of the present invention include chitosan-arginine compounds and chitosan-L/D natural amino acid derivative compounds, co-derivatives of said chitosan derivative compounds, and salts of said chitosan derivative compounds.

The invention relates to the technology for producing continuous mineral fibres from rocky raw material, in particular from basalt rock, from mixtures based on basalt rock, from glassy industrial and technical waste products. The production process for mineral fibres comprises forming a withdrawal region for the melt in the distributor duct such that the ratio of the height of the melt in the distributor duct to the height of the melt in the withdrawal region is in the range from 3.4 to 20.

A plurality of different structural members for reinforcing a plate-like structure, such as a bushing tip plate (T) for intended use in forming fibers from a fluid material supplied to a bushing assembly, are disclosed. Each reinforcing member (10a, 10b) includes a body having a first portion (12) for attachment to the structure and a second portion (20) having a profile with a variable height including at least one apex (A). The body may be integrally formed of a single piece of material, or two or formed from more separate pieces of material bonded or secured together. The body may be T-shaped (312, 320), L-shaped (310), or F-shaped (212, 220) in cross-section. The second portion of the body may have an inverted V-shaped profile (520), an inverted W-shaped profile (620), or an arcuate profile (420). The at least one apex may be located at the midpoint (M) or elsewhere along the length of the body.

摘要:
A multi-screen mixing apparatus for installation in a fiber-forming bushing used in the manufacture of glass fibers. The multi-screen mixer attaches to the walls of the bushing, and includes a first screen having openings therein through which the glass flows and a second screen having openings through which the glass flows longitudinally spaced from the openings in the first screen such that the molten glass must flow in a non-linear path as it passes through the screens. Additional screens can be added to cause additional flow diversion to further mix the molten glass.

A spinner (12) is adapted to be fixed at one end of a rotatable shaft (14) in a fiberizer (10), the spinner including a radial wall (16) extending radially out from the shaft and having an upper surface (35), a dam (34) separating the upper surface into an inner portion (81) and an outer portion (83), a lower surface (37), at least one first flow hole (36) connecting the upper surface to the lower surface, and at least one second flow hole (94) connecting the inner portion and the outer portion of said upper surface, and an outer peripheral wall (18) connected to the radial wall and having a plurality of orifices (20) therethrough.
摘要:
An apparatus (10) is provided for producing continuous glass filaments (30). The apparatus (10) comprises a bushing (20) for supplying streams of molten glass and a drawing device (40) adapted to draw the streams into continuous glass filaments (30). A cooling device (50) is also provided and is located adjacent to the bushing (20) for drawing in heated air from a filament forming area beneath the bushing such that heat is convectively transferred away from the filament forming area.
摘要:
Oxide dispersion strenghtened metals (2) are formed into a profiled member (6) by a ring rolling process and are then employed as a spinner (6C) in the manufacture of fibrous glass. Sufficient hot working and annealing are provided to develop the desired coarse grain structure.
