Coating Process Regimes in Particulate Film Production by Forced-Convection-Assisted Drag-Out

This project aims at altering the conveyor speed for maximum productivity and modifying the oven in order to increase the efficiency of powder coating process involved in painting the components of lifts. The primary thing to be considered while modifying the oven is the heat source provided. Most of the industries use forced convection for heating up the product in order to cure the powder coating process. This project aims at providing infrared radiation as the heat source to cure the powder over the metal surface. Forced convection is advantageous for more complex shapes. But the components of lifts are not of complex shapes. So, it would be efficient to use infrared. The forced convection system requires long heat up time, high energy consumption, large floor area and some additional setups for air circulation inside the oven. Infrared radiation heating would eliminate these drawbacks. The infrared radiation would be absorbed by the material in order to heat up. This is more efficient in case of curing the powder coated parts. Because, in case of forced convection first the paint in form of powder is heated and then the heat is transferred to the metal surface. Whereas in case of infrared heating, the metal would be heated first and then it would be transferred towards the powder paint. In other words, we could say that the infrared radiation heating provides backward heating which would increase the efficiency and life of the paint coated. Temperature control and instant heating are also the advantages of infrared heating. Hence designing the infrared source for the given metal and powder specifications is done in this project.

Base Paper

The fraction of deinked pulp for coated paper production is continually increasing, with some mills using 100% deinked pulp for the base paper. The brightness of the coated paper made from deinked pulp may be reached through a combination of more or less extensive deinking, compensated by appropriate coating, to optimize costs overall. The authors proposed general optimization methods combined with Kubelka-Munk multilayer calculations to find the most economical combination of deinking and coating process that would produce a coated paper made from DIP, at a given target brightness, while maintaining mechanical properties.

Average Size

Coating color stability, as defined by changes in its solid particle fraction, is important for runnability, quality, and costs of a paper coating operation. This study sought to determine whether the size or density of particles is important in size segregation in a pigment coating process. We used a laboratory coater to study changes in coating color composition during coating operations. The results suggest that size segregation occurs for high and low density particles. Regardless of the particle density, the fine particle size fraction (<0.2 μm) was the most prone for depletion, causing an increase in the average size of the particles. Strong interactions between the fine particles and other components also were associated with a low depletion tendency of fine particles. A stable process and improved efficiency of fine particles and binders can be achieved by controlling the depletion of fine particles.

From Film Practice to Data Process critically examines the practices of independent digital feature filmmaking in contemporary Britain. The business of conventional feature filmmaking is like no other, in that it assembles a huge company of people from a range of disciplines on a temporary basis, all to engage in the collaborative endeavour of producing a unique, one-off piece of work. The book explicitly interrogates what is happening at the frontiers of contemporary ‘digital film’ production at a key transitional moment in 2012, when both the film industry and film-production practices were situated between the two distinct medium polarities of film and digital. With an in-depth case study of Sally Potter’s 2012 film Ginger & Rosa, drawing upon interviews with international film industry practitioners, From Film Practice to Data Process is an examination of film production in its totality, in a moment of profound change.

Cross-border Implications: Transnational Haunting, Gender and the Persistent Look of The Eye

Eastern Traditions

The Eye (Gin Gwai, 2002) and its two sequels (2004, 2005) deal with pan-Asian film production, gender, and identity. The films seem to embrace a transnational outlook that that fits a shared Southeast Asian cinematic and cultural agenda. Instead, they disclose tensions about Hong Kong’s identity, its relationship with other countries in the region, and its mixture of Western and Eastern traditions (Knee, 2009). As horror films, The Eye series feature transpositional hauntings framed by a visual preference for understanding reality and the supernatural that is complicated by the ghostly perceptions of their female protagonists. Thus, the issues explored in this film series rely on a haunting that presents textual manifestations of transposition, imposition, and alienation that further evidence its complicated pan-Asian look. This chapter examines the films’ privilege of vision as catalyst of a transnational, Asian Gothic horror aesthetic that addresses concepts of identity, gender, and subjectivity.

This article considers the working practices of British cinema's only major female film producer during the early-to-mid post-Second World War era, Betty E. Box (1915–99). Via reference to her extensive archive at the British Film Institute and the films Campbell's Kingdom (1957), The Wind Cannot Read (1958) and Hot Enough for June (1964), the article charts how Box initially envisaged multi-generational casting for roles that were eventually taken by long-term collaborator Dirk Bogarde. It considers the manner in which she approached the diplomatic complexities of location shooting, with particular focus on Ralph Thomas's military romance The Wind Cannot Read, the first British film to be shot in India for twenty years at the time of its production. The reasoning for Box's ongoing absence, as a female creative figure, from scholarship addressing British cinema, and film production more generally, will also be addressed.

Making Art

In an era of public consciousness about gendered inequalities in the world of work, as well as recent revelations of sexual harassment and abuse in theatre and film production, Beckett's Catastrophe (1982) bears striking resonances. This article will suggest that, through the figure of its Assistant, the play stages the gendered nature of the labour of making art, and, in her actions, shows the kind of complicit disgust familiar to many who work in the entertainment industry, especially women. In unpacking this idea, I conceptualise the distinction between the everyday and ‘the event’, as in, between modes of quotidian labour and the attention-grabbing moment of art, between the invisible foundations of representation and the spectacle of that representation. It is my thesis that this play stages exactly this tension and that deploying a discourse of maintenance art allows the play to be read in the context of the labour of theatre-making. Highlighting the Assistant's labour becomes a way of making visible the structures of authority that are invested in maintaining gender boundaries and showing how art is too often complicit in the maintenance of social hierarchies.

Transfer Flow

The problem of combined free-forced convection and mass transfer flow over a vertical porous flat plate, in presence of heat generation and thermaldiffusion, is studied numerically. The non-linear partial differential equations and their boundary conditions, describing the problem under consideration, are transformed into a system of ordinary differential equations by using usual similarity transformations. This system is solved numerically by applying Nachtsheim-Swigert shooting iteration technique together with Runge-Kutta sixth order integration scheme. The effects of suction parameter, heat generation parameter and Soret number are examined on the flow field of a hydrogen-air mixture as a non-chemical reacting fluid pair. The analysis of the obtained results showed that the flow field is significantly influenced by these parameters.
