Radialtätning till Retarder

This thesis has the overall objective to develop the optimum sealing system between the retarder and transmission. Today, there is a pressure-relief and two radial seals separation between the retarder and transmission. It has been found that carbon residue formation may occur between retarder axle and seal lips with, in some cases, leakage as a result.We have in this thesis tried to explain the phenomenon of carbon residue, how it is formed and why it can be seen just on the seals? A rig test was conducted where we show how friction, speed, transmission temperature and mitigation phases of the retarder affects temperatures in the sealing environment. Factors affecting the coke structure are reported, together with proposals for measures that provide a mitigating seal environment.

Fermented sausage : product development at Lindell's Gårdsslakteri

Product development is a risky business; many products never yield profit, but it is also ne-cessary for a company?s survival in a competitive business where the costumers change their requests constantly. Consumer-led product development is developed from the wish to fill the consumer?s needs and expectations and thereby be more likely to succeed. Lindell?s Gårdsslakteri AB is a local slaughter and meat processor in Västergötland.

Genusperspektiv på kulturmiljövård. En diskussion om genus i bebyggelseantikvarisk verksamhet

This Mag. thesis discusses how a gender perspective could be implemented in themanagement of cultural heritage focusing on the built environments in Sweden.The thesis further argues for the need of a gender perspective on the conservationof cultural heritage.The two main approaches, additive through the perspective of the women?s part inhistory and integrated gender perspective, are thoroughly presented in the thesis.In the additive gender approach built objects that represent women?s experiencesand lives are added to a history that traditionally represents men and theirexperiences. The integrated gender perspective includes a gender in all activitiesas an instrument in a historic analysis. The gender perspective illustrates therelation between the sexes.

"Åreandan" : Som Gnosjöandan, bland kvinnor?

The female labour is still a rather unexploited resource in many parts of the world. Unleashing women?s potential, giving them the possibility to start their own enterprises would increase the economic growth. Not only does women's entrepreneurship foster greater equality in the world but it also creates a more versatile economy. Sweden is considered to be one of the most equal countries in the world; still, entrepreneurship is an area with sharp gender differences, especially in some industries.

It is easier to swallow an elephant in pieces. A way of measuring flexibility and quality. A study of DAS.

Upon marketing the system in Europe and the USA cost savings generated from reduced work force have been prevailing. Since the cost of labour is much lower in the Asia Pacific region other factors have to be stressed. The parameters of flexibility and quality assurance may however cover any initial investment in a production system. Our purpose is to value flexibility and quality in a manufacturing context, applied to DAS, in order to use it in investment calculations. In order to make an adequate estimation of different companies, due to problems associated with acquiring correct figures, the Key Success Factors needs to be examined so that the gathering of numbers can be conducted with more focus.

Titel: Innovate or Stagnate! ? Open innovation in manufacturing small and medium-sized businesses in Småland.The purpose of the study is that, from a leadership perspective (innovationmanagement), create a better understanding of open innovation in manufacturing small and medium-sized enterprises. The study therefore intends to contribute to the understanding of how open innovation processes leads to greater innovation in manufacturing small and medium sized businesses.We have used a qualitative research method and adopted an abductiveapproach. We made interpretations and created meaning based on our research results.Our theoretical framework is based primarily on Chesbroughs (2003) research on open innovation. Based on this model, we have selected a number of other theories, which we perceived as prerequisites for small andmedium sized companies in open innovation processes.

Additiv tillverkning för serieproduktion : Under vilka förutsättningar lämpar det sig?

Additiv tillverkning, eller ?Additive manufacturing? (AM) är den ISO-standardiserade termen på tillverkningsmetoder som bygger detaljer genom att lagervis addera material. Det är en teknik som främst har använts till prototyptillverkning och fortfarande gör men som mer och mer börjar få fäste som tillverkningsmetod för slutanvändningsprodukter. Syftet med denna rapport är att undersöka under vilka förutsättningar AM lämpar sig som tillverkningsmetod för detaljer av plast. Förutsättningarna delas in i ett ekonomiskt, tekniskt och kunskapsmässigt perspektiv.

Additivt tillverkat material

SammanfattningDet här projektet behandlar området Additiv Tillverkning (AM) för metalliska material och undersöker om det är lämpligt att använda vid produktion inom flygindustrin. AM är en relativt ny tillverkningsmetod där föremål byggs upp lager för lager direkt ifrån en datormodell. Teknikområdet tillåter i många fall större konstruktionsfriheter som möjliggör tillverkning av mer viktoptimerade och funktionella artiklar. Andra fördelar är materialbesparing och kortare ledtider vilket har ett stort ekonomiskt värde.En omfattande litteraturstudie har gjorts för att utvärdera alla tekniker som finns på marknaden och karakterisera vad som skiljer de olika processerna. Även maskiners prestanda och kvalité på tillverkat material utvärderas, och för varje teknik listas möjligheter och begränsningar.

It is also well known that the factory planning shapes the manufacturing process to a great extent. Consequently it is logical to assume that the manufacturing companies? factory planning process plays a major role in the work for increased sustainability.

Kartläggning av Kassationerpå Bubs Godis

The waste of material is a big expense for manufacture companies caused by lack of quality. The cost by lack of quality often totaled to a big percentage share of the turnover when all cost related to lack of quality is included. New manufacturing systems like Lean production or Just In Time demands better internal quality for the manufacturer. To make those manufacturing system with small and none buffer stock successful the quality improvement continuously have to be developed.Measuring of waste of material in Bubs Candy?s factory where not simple due to the products does not have a permanent weight during the manufacturing process.

En studie av metodbyte vid sintring av hårdmetaller till mikrovågsintring samt dess ekonomiska fördelar : Självständigt arbete i teknisk fysik med materialvetenskap & Självständigt arbete i kemiteknik

The aim with this study was to investigate the effects a change of manufacturing process would have on the mechanical properties of drill bits made of a WC/Co composite used for stone cutting. The method used today is sintering, where the material is heated in a conventional sintering oven. The other method was microwave sintering, where the material is heated by radiation in the microwave region. Also an investigation of the manufacturing cost were made.The main difference between the two heating methods is that the conventional way is a rather slow process and the microwave method is very fast. The material is also heated homogeniously in the method with mirowaves, aposed to the case with the conventional sintering where the material is heated from the outside in.This makes the material harder and more wear resistent.
