Projektgruppen har fått i uppdrag att ta fram ett produktutvecklingskoncept utifrån en befintlig produkt ur ErgoSafe AB:s sortiment. Det finns ett stort intresse för höj- och sänkbara glasräcken där krog- och restaurangbranschen dominerar. Uteserveringar försedda med ClickitUp är inte lika utsatta vid sämre väderförhållanden, vilket ger möjlighet till längre och fler besök. ErgoSafe har identifierat en betydande anledning till varför försäljningen inte har gått som befarat, som beror på att flertalet kommuner förbjuder ingrepp i markbeläggningen. Examensarbetet kommer att bistå ErgoSafe i deras arbete för att förenkla tillväxten i försäljningen genom att ta fram en modulanpassad variant som inte kräver markingrepp., The project group has been commissioned to produce a product development concept, based on an existing product called ClickitUp from ErgoSafe AB’s product range. The market has shown a great interest for height adjustable glass railing. Where the restaurant and tavern sector is dominant. An outdoor seating provided with ClickitUp are not as vulnerable to adverse weather conditions which is likely to result longer and more visits, since it will prolong the outdoor season. ErgoSafe has identified a significant reason the sales have not been going as good as planned, since most municipalities prohibit intervention in the ground around the restaurants. This thesis aims to assist ErgoSafe AB in their work to simplify the growth of sales by developing a modular variant that does not require ground intervention.

This report documents the laboratory measurements made to resolve specificity questions concerning the chemical conversion techniques for measurement of stratospheric trace species NO2, N2O5, and HNO3 to NO (Which is the measurable species). Particular emphasis was placed on the conversion of NO2 to NO by both catalytic and photolytic converters, thermal conversion of N2O5 and HNO3 to N02 with and without possible interfering gases, and the feasibility of measuring total odd-nitrogen concentration using catalytic thermal conversion to NO. The laboratory measurements were generally carried out at ppm concentrations at STP conditions. The GEARS/EPISODE computer code was used to model both the laboratory reactions and the behavior of the technique at stratospheric conditions. The laboratory measurement and stratospheric simulations lead to the recommendation to develop a flight prototype of a Hybrid Gas Conversion System consisting of a number of instrumentation modules. The first module would be a Total Odd-Nitrogen module (and NO) based on high temperature catalytic conversion of the odd-nitrogens and chemiluminescent detection of NO. The second module would be an NO2/NO module based on NO2 photolysis and NO chemiluminescent detection. Other modules could consist of an O3 UV photometer, and N2O gas chromatograph, and other appropriate modules that are ready at flight time. (Author), See also Rept. no. FAA-AEQ-78-10, AD-A059 330.
