  • Patent number: 7368616
    Abstract: The instant invention relates to a new method for the synthesis of monomers and their use inter alia in the manufacture of semiconductive polymers. Monomers, in particular, asymmetric monomers, such as asymmetric fluorene compounds, are valuable material in the manufacture of semiconductive polymers. The know methods for producing asymmetric monomers, such as asymmetric fluorene compounds, are expensive due to the formation of by-products. The method according to the present invention avoids the formation of such by-products and is described in more detail in claims 1 to 14.

  • Patent number: 7313586
    Abstract: An adder-subtracter circuit being adapted to process two binary input numbers in order to generate the sum or the difference of the two processed numbers depending on the state of a subtract input signal. The circuit has the capability to feed back the result of the processing to itself in order to process one input number together with the result of a previous processing instead of the second binary number.

  • Patent number: 7219118
    Abstract: A system for adding multiple sets of numbers via a fixed-width adder includes an adder for receiving each of the sets of binary numbers at corresponding sets of adder inputs, and for generating a sum of each set of binary numbers. Each set of numbers defines a distinct data path through the adder. For each set of numbers, the system further includes a logic gate for inhibiting a carry path, from each portion of the adder corresponding to each carry path, to a next adjacent carry path. The system isolates two or more contiguous data paths through the fixed-width adder corresponding to each of the two or more sets of two binary numbers. The invention prevents unwanted signals from crossing summing lane boundaries in different processing modes. The same adder logic can thus be used for each processing mode by varying the combination of mode select control signals.

  • Publication number: 20060086590
    Abstract: A sawtooth merging conveyor system that more accurately controls the position of merging cartons or other objects of varying size, shape, weight or condition. Rollers define entry portions configured to abut supply conveyors and a conveyor belt covers a main portion of the conveyor system. The rollers of the entry portions convey the cartons from the supply conveyors onto the conveyor belt. Slip of the cartons is reduced by the friction of the conveyor belt surface. The rollers of the entry portions may have a coating that improves roller grip of the cartons and matches the thickness of the belt to reduce slip and improve transitioning of the cartons onto the belt. A guide rail defines an outer edge of the entry portions and can includes a plurality of guide rollers connected to the main conveyor drive to urge packages onto the conveyor belt of the main portion.
