Abstract: This disclosure relates to a soldering system containing a soldering apparatus and a heating apparatus. The soldering apparatus includes a heating plate having a body defining a plurality of first air exits, each first air exit extending through the body of the heating plate and the heating plate being configured to supply hot air through the first air exits; a cover disposed on the heating plate, the cover and the heating plate defining a hot air chamber; a plurality of axially movable positioning shafts extending though the body of the heating plate, in which each shaft has a first end and a second end, the first end is in the hot air chamber, and the second end is outside the hot air chamber; and a conduit attached to the cover, the conduit being configured to supply hot air to the hot air chamber.

Abstract: The present invention relates to a method for accelerating oxidation of lipids comprising the step of holding a lipid composition in the presence of cumin for a prolonged time at an elevated temperature. Further aspects of the invention are the resulting lipid composition as well as food products such as concentrated seasoning or flavoring products, condiments, sauces, gravies or ready-to-eat food products comprising said lipid composition.

Abstract: A solar cell (100) includes a photoelectric conversion layer (120) having a front surface (121) and a back surface (123), a back electrode (110) disposed on the back surface (123) of the photoelectric conversion layer (120), a plurality of electrically conductive fingers (130) disposed on the front surface (121) of the photoelectric conversion layer (120), and a plurality of primary bus bars (140) disposed on the front surface (121) of the photoelectric conversion layer (120). Each primary bus bar (140) is electrically connected to a plurality of electrically conductive fingers (130). The solar cell (100) can include from 4 to 12 primary bus bars (140) on the front surface (121) of the photoelectric conversion layer (120) and the primary bus bars (140) on the front surface (121) of the photoelectric conversion layer (120) have a total surface area of at most about 4 cm2.
