curing of polyurethane coatings: ultraviolet beam. july 1980-november 1989 (a bibliography from world surface coatings abstracts). rept. for jul 80-nov 89

this bibliography contains citations concerning the curing of urethane or polyurethane coatings using ultraviolet radiation. this discussion is specific to ultraviolet curing as compared to photocuring or radiation (eb) curing, which are treated under a separate subject. these coatings may be described as inks, paints, lacquer, adhesives,..

sio overcoating and polishing of cfrp (carbon fiber reinforces plastic) telescope panels

development of carbon fiber reinforced plastic (cfrp) panel overcoating and polishing is structured in two parts. the first part utilized a short series of experiments to determine the feasibility of overcoating and polishing cfrp panels, and the second part employes a systematic approach to optimize techniques learned questions which req..

heat recovery from hot liquid laundry effluent using a coil-in-shell heat exchanger. a demonstration at belgrave and wigston ltd (leicester)

cost savings of pound 8,020/year have been achieved at belgrave and wigston ltd of leicester, by the installation of a system to recover medium-grade heat from hot washing machine effluent for use in the washing process. the effluent is collected from the four batch washer extractors in the garment rental wash-room; the five batch washer ..

effects of the diffusion with chain enzymatic reactions optimization of a fixed glucoamylase reactor for the hydrolysis of maltodextrins

the development of the fixed cells and enzymatic processes implies, for the optimization of these heterogenous bioreators, a better control of the quantitative and qualitative aspects of their implementation. more precisely it is important to understand the effects of the diffusional phenomena on the catalytic activity, the productivity, ..

traitements de surface de fibres de carbone en milieu organique etude par elements finis de l'essai de dechaussement (surface treatments of carbon fibers in organic solution. study by finite elements of the pull-out test). technical rept

in order to carry out surface treatments on continuous carbon fibers, variations were made in various parameters affecting the grafting of nitrogenous radicals. among the variations, the temperature and the potential applied to the anode play a predominant role without involvement of parasitic reactions (particularly in the case of the po..

organisation structurale et texturale de polymeres traites thermiquement, relations avec les proprietes mecaniques (textural and structural organization of the heat treated polymers: mechanical properties relationships). final rept

the microstructure and the texture of ceramics obtained from organometallic polymer manufacturing are investigated. the interfaces and the bulk structure of the carbon fiber resin composite materials are studied. the transmission electron microscopy and x ray diffraction are the basic applied techniques. concerning microstructure and text..

traitements de surface de fibres de carbone en milieu organique etude par elements finis de l'essai de dechaussement (surface treatments of carbon fibers in an organic environment. finite element analysis of pull-out tests)

techniques of surface treating carbon fibers by varying different parameters controlling nitrogen link-up are described. changes in temperature and anode potential play a large role in the creation of parasitic reactions. if possible, the solution within the fiber should be renewed periodically. nitrogen concentrations of up to 22 percent..

design and fabrication requirements for low noise supersonic/hypersonic wind tunnels

a schematic diagram of the new proposed supersonic low disturbance tunnel (sldt) is shown. large width two dimensional rapid expansion nozzles guarantee wide quiet test cores that are well suited for testing models at large angle of attack and for swept wings. hence, this type of nozzle will be operated first in the new proposed large sca..
