Operational characteristics of the NNPB plunger in the glass container industry

Penlington, Roger January 1994 (has links)
Although glass containers are an everyday item the process responsible for their production is not scientifically understood. Developments have occurred slowly over many years, mostly on a trial and error basis and in response to economic pressures. The narrow neck press and blow (NNPB) process has evolved in recent years as a result of attempts to reduce container weight. The fundamental component of the NNPB process is the plunger which is responsible for the initiation of the cavity and control of glass distribution within the container. The NNPB plunger functions as a form tool and as a heat exchanger, thus requiring a carefully selected range of properties. The Engineer responsible for tooling selection and operation has a limited resource of scientific knowledge to enable the performance of the process to be optimised. The current NNPB plunger is subject to high rates of wear and is directly responsible for product defects, thermal instability and limits process speed. The work presented here is a scientific study of current NNPB plunger technology. The plunger has been investigated in relation to the requirements of the glass container forming process. The materials used have been examined, before and after use and their wear modes explained. The thermal properties of the plunger have, as far as is possible, been examined during the forming cycle. When combined with results from the characterisation of transformations occurring in the material, during its service life, operational requirements have been explained. The ability of the NNPB plunger to remove heat from the glass has been investigated, and has illustrated significant deficiencies in the current arrangement. Details are given as to how these deficiencies may be overcome to enable the Engineer to regain control of the process. As a result of the study many phenomena exhibited by the NNPB plunger are now understood and may be related to the performance of the process.

No. of bitstreams: 1 325441.pdf: 1380791 bytes, checksum: 17e655d4d376a46f1f74f7ac2c4635a3 (MD5) Previous issue date: 2013 / O estudo mostra a importância da conteinerização no comércio exterior e análise os determinantes da competitividade do comércio exterior, aplicada a contêineres e na forma de um estudo de caso do Porto de Santos. As análises foram realizadas com base na teoria gravitacional de comércio, em que comércio internacional é positivamente influenciado pelo tamanho das economias dos países parceiros comerciais e impedâncias, tais como a distância entre eles e as condições de transporte e logística (condições de acessos, principalmente). Foi apresentado o modelo gravitacional e sua compatibilidade com as teorias tradicionais de comércio internacional, como o modelo gravitacional de Deardorff (1998), deduzido a partir do Modelo Heckscher-Ohlin. Empiricamente, foi feita, assim, uma análise dos determinantes do comércio exterior de contêineres, no Porto de Santos, de acordo com o modelo gravitacional ampliado, em que a quantidade exportada e importada é função das rendas dos países de origem e destino e da distância entre as microrregiões de produção ou consumo e o porto. Foram aplicados: um modelo de séries temporais AR(1) multivariado e painéis de dados dinâmicos (com efeitos fixos e variáveis). Os resultados obtidos a partir da estimação do modelo de séries temporais indicam que as variáveis explicativas, PIB e variável dependente defasada, são significativas e a elasticidade renda de curto prazo das exportações e importações de contêineres é alta. Os resultados das estimações dos modelos de painel de dados, de forma geral, indicaram que as variáveis renda são significativas relacionam-se com a variável dependente como o esperado de acordo com o modelo gravitacional. Porém, as distâncias foram significativas e apresentaram relação negativa apenas para as exportações. Por fim, os exercícios de projeção de demanda de curto prazo e avaliação da qualidade das projeções, a partir do cálculo de medidas de erro permitiram inferir que os modelos de painel de dados resultam em projeções mais precisas do que os modelos de séries temporais.<br>

The adhesion characteristics of a laminated aluminium/polyester system

Liu, Jiping January 1993 (has links)
Adhesion aspects of laminated aluminium/polyester systems have been studied before and after mechanical deformation. The work has been carried out in collaboration with a producer of beverage cans, and the reasons for the adhesion reduction observed during the deep drawing and wall ironing process has provided the focal point for the work. Laminates were manufactured from commercial polyester film and commercially anodised (2 types) or chromium phosphated aluminium coil stock. The morphology of the pretreated aluminium surfaces has been investigated by using scanning electron microscopy. The chemical composition and the composition variation with depth of the pretreated aluminium surfaces have been studied by XPS sputter depth profiling. It is found that the CP and PAAI, PAAII pretreatments have reduced the amount of magnesium in the top layer of aluminium surfaces. An intimate contact between the polyester film and the aluminium substrate of the laminates and the thicknesses of the pretreated layers have been observed by cross- sectional TEM following sample preparation by chemical sample thinning and microtoming. Based on angle resolved XPS and SIMS investigation, the locus of failure of the can systems produced from the CP and PAAI treated aluminium has been defined as within the polyester film but very near the interface. The thickness of the residual polyester overlayers has been estimated. A peel test has been used to evaluate the adhesion level of the cans. The order of the adhesion level of the cans produced from different surface pretreated aluminium has been found to be; PAAII > CP > PAAI. Chemical exposure methods have been established to make the investigation of interfacial surfaces of the laminates possible by SEM. A shear lag analysis has been carried out to demonstrate the mechanical deformation behaviour of the laminates during the deep drawing and wall ironing process. A relationship between the thickness of the pretreated layer and the fragment size has been proposed. It is found that the pretreated layer fragment characteristics is very important. Fine and uniformly distributed fragments with small separation distance in the aluminium substrate of the cans contribute to the adhesion level through crack pinning effect. A comprehensive model for adhesion loss during deep drawing and wall ironing process has been proposed.

Deceptive Environments for Cybersecurity Defense on Low-power Devices

Kedrowitsch, Alexander Lee 05 June 2017 (has links)
The ever-evolving nature of botnets have made constant malware collection an absolute necessity for security researchers in order to analyze and investigate the latest, nefarious means by which bots exploit their targets and operate in concert with each other and their bot master. In that effort of on-going data collection, honeypots have established themselves as a curious and useful tool for deception-based security. Low-powered devices, such as the Raspberry Pi, have found a natural home with some categories of honeypots and are being embraced by the honeypot community. Due to the low cost of these devices, new techniques are being explored to employ multiple honeypots within a network to act as sensors, collecting activity reports and captured malicious binaries to back-end servers for later analysis and network threat assessments. While these techniques are just beginning to gain their stride within the security community, they are held back due to the minimal amount of deception a traditional honeypot on a low-powered device is capable of delivering. This thesis seeks to make a preliminary investigation into the viability of using Linux containers to greatly expand the deception possible on low-powered devices by providing isolation and containment of full system images with minimal resource overhead. It is argued that employing Linux containers on low-powered device honeypots enables an entire category of honeypots previously unavailable on such hardware platforms. In addition to granting previously unavailable interaction with honeypots on Raspberry Pis, the use of Linux containers grants unique advantages that have not previously been explored by security researchers, such as the ability to defeat many types of virtual environment and monitoring tool detection methods. / Master of Science

[pt] Dentro desta nova busca pela unitização do processo logístico, surge a figura do Operador de Transporte Multimodal (OTM). Esta nova categoria permite a uma única empresa ser responsável por toda a cadeia de transporte, sob a segurança de uma única documentação (Conhecimento de Transporte Multimodal - CTMC), mesmo que a carga utilize diversos modais de transporte. No Brasil, uma legislação específica para operadores de transporte multimodal, foi criada em abril de 2000, através da lei de nr. 9.611/98. A dissertação pretende mostrar através de pesquisas, e fatos reais qual a fundamentação deste modelo operacional e qual o status atual desta lei a aplicabilidade no processo logístico atual das principais empresas nacionais. Ao final propor soluções ou idéias para que o operador multimodal possa ampliar suas atuações no Brasil. / [en] Within this new search for unitização logistics of the process, there is the figure of the Multimodal Transport Operator (OTM).
