    In certain market situations the llJ9rkeLv_al_ue of dehydrated lu_cern can be increased dramatically by separati~g the different levels of protein by applying a pneumatic separation process. The pneumatic separation ...
  • Barnard, Ludrick Johannes (Bloemfontein: Central University of Technology, Free State, 2002)
    The spincasting process is currently used mainly for casting of low melting point materials for products such as costume jewellery and fashion items where dimensional accuracy is not very important. The shrinkage of the ...
  • Schenker, Rudolf (Bloemfontein: Central University of Technology, Free State, 2001)
    Computer Aided Design (CAD), Rapid Prototyping (RP) and Computer Aided Tomography (CAT) technologies were researched. The project entails a unique combination of the abovementioned technologies, which had to be mastered ...
  • Oehley, John McGregor (Bloemfontein: Central University of Technology, Free State, 2000)
    Due to the popularity of 3-dimensional CAD designs, the methods of manufacturing from these designs are increasing all the time. Rapid prototyping designers and manufacturers are now able to grow prototypes from the ...
  • van Zyl., Pieter Benhardus (Bloemfontein: Central University of Technology, Free State, 1997)
    For this research a problem was identified for the small scale pasteurizing of milk in rural areas of the Free State. The sun was utilized as an energy source for the pasteurizing process. Several experiments were carried ...
  • van der Walt, Bernard (Bloemfontein: Central University of Technology, Free State, 1997)
    Most commercially available signal generators make use of a phase-locked loop in combination with analogue frequency synthesis to generate the desired frequency range. Advances in the development of components being used ...
