Abstract: "MéTODO PARA MODULAR OS NìVEIS DE UM PRODUTO METABóLICO OU BIOSSINTéTICO EM UMA PLANTA, VETOR, CéLULA GENETICAMENTE MODIFICADA, PLANTA GENETICAMENTE MODIFICADA, SEMENTES OU OUTRO MATERIAL REPRODUTIVO, PRODUTO, E, SISTEMA BIORREATOR". A presente invenção refere-se em geral ao uso de plantas como biorreatores para a produção de moléculas possuindo propriedades úteis tais como inter alia polímeros, metabólitos, proteínas, fármacos e nutracêuticos. Mais particularmente, a presente invenção contempla o uso de gramíneas, e ainda mais particularmente de gramíneas C4, tal como cana-de-açúcar, para a produção de uma variedade de produtos tais como, por exemplo, poli(hidróxialcanoatos), PHBA, vanilina, indigo, ácido adípico, 2-fenil-etanol, 1,3propanodiol, sorbitol, polimeros de frutano e ácido lático bem como outros produtos incluindo, inter alia, outros plásticos, sedas, carboidratos, proteínas nutracêuticas e terapêuticas e anticorpos. A presente invenção refere-se adicionalmente às plantas transgênicas e, em particular, às plantas gramineas C4 transgênicas, capazes de produzir os compostos citados acima e outros produtos, e aos métodos para gerar tais plantas. A capacidade de utilizar a taxa de crescimento elevada e a fixação de carbono eficiente de gramineas C4 é vantajosa, pelo fato de que evita as penalidades de crescimento significativas observadas em outras plantas, e os resultados de rendimentos altos de produto desejado sem necessariamente causar efeitos deletérios concomitantes sobre as plantas individuais. Em adição, a gramínea C4, cana-de-açúcar, é particularmente vantajosa, visto que em adição às características comuns de todas as gramíneas C4, esta planta acumula sacarose. Esta armazenagem de sacarose proporciona um pronto fornecimento de energia e de compostos baseados em carbono o que pode adicionalmente evitar quaisquer efeitos deletérios sobre o crescimento da planta associada com a produção do produto. A presente invenção proporciona, portanto, um sistema biorreator compreendendo uma planta geneticamente modificada projetada para produzir produtos biossintéticos ou metabólicos específicos de interesse.

Abstract: The invention describes a clamp for rails that is produced from resilient steel bar with multiple bends. The first section (11) of the rail clamp (9, 10) is essentially horizontally arranged, while the last section (14) rests on the rail flange (5). The second section (12) curves upwards in the vertical plane that passes through the first section (11). The remaining sections of the clamp lie all on the side of the first section that faces the rail. The fastening arrangement comprises an anchoring part (20) where the supporting surface (23) for a supporting section of the clamp (9, 10) is located essentially vertically above the locating hole (24) of the clamp (9, 10).

Abstract: This invention relates to glass (1,4) carrying an electroconductive coating (7) and, in particular, to a method of applying bus bars (3,6) on the glass (1,4) to establish electrical contact with the coating (7) and to coated glass (1,4) provided with bus bars (3,6) in accordance with the invention. The method of applying the bus bars (3,6) to the electroconductive coating (7) involves arc spraying molten metal e.g. aluminium on to the coated glass (1,4) in the required configuration which can be defined by either placing a stencil over the surface of the coated glass (1,4) or using adhesive tape (5) to define the required configuration, and then spraying the molten metal. Aluminium has been found to be a most suitable metal for the bus bars and this can be oversprayed with a layer of copper, zinc, tin, a tin alloy, stainless steel, nickel, brass or copper nickel alloy if required. In certain circumstances, for use in architectural applications for e.g. electromagnetic shielding purposes, the bus bars are wrapped around the edge of the glass to provide electrical contact means when the glass is used in a laminate or a double glazing unit.
