  • Patent number: 9227803
    Abstract: The device for separating product parts of a multi-part, flat product includes a receiving unit for receiving the product, a device for separating the product parts and a retaining device for acting on one of the product parts for the purpose of maintaining the separation of the product parts. The receiving unit includes a first friction element and a second friction element, which is movable with respect to the first friction element. The two friction elements are arranged on the receiving unit such that the product can be firmly clamped between the friction elements. The friction elements are designed such that the static friction between the product part and the friction element assigned to this is greater than the static friction between the product parts, so that the product parts can be moved with respect to one another given a relative movement between the two friction elements firmly clamping the product.

  • Patent number: 7026478
    Abstract: A process for the production of compounds Ar—R1 by means of a cross-coupling reaction of an organometallic reagent R1-M with an aromatic or heteroaromatic substrate Ar—X catalyzed by one or several iron salts or iron complexes as catalysts or pre-catalysts, present homogeneously or heterogeneously in the reaction mixture. This new invention exhibits substantial advantages over established cross coupling methodology using palladium- or nickel complexes as the catalysts. Most notable aspects are the fact that (i) expensive and/or toxic nobel metal catalysts are replaced by cheap, stable, commercially available and toxicologically benign iron salts or iron complexes as the catalysts or pre-catalysts, (ii) commercially attractive aryl chlorides as well as various aryl sulfonates can be used as starting materials, (iii) the reaction can be performed under “ligand-free” conditons, and (iv) the reaction times are usually very short.

    Abstract: The present invention relates to enhancement of the cycle life of a zinc chromium based catalyst used in the synthesis of 2-methylpyrazine by increasing the reaction temperature step-wise, starting from a low temperature, while monitoring the levels of total conversion and selectivity towards pyrazine. The catalyst can be regenerated after each cycle of use without substantial loss of activity.

  • Patent number: 6225471
    Abstract: Alkyl pyrazine compounds are prepared by heating and refluxing an aqueous mixture of an ammonium-containing compound and at least one acyloin compound. Reaction product may be isolated from the reacted mixture by adjusting the pH of the reacted mixture, separating solid material from the pH-adjusted reacted mixture, adding water to the separated solid material to form a solution, allowing product to crystallyze from the solution and then collecting the crystalline product. Alternatively, the reactants may be heated, refluxed and sublimed to collect the pyrazine reaction product on a cooled sublimation collection surface.

  • Patent number: 5880129
    Abstract: A discovery underlying this invention is the concordance between particular cellular signaling mechanisms and cancer cell growth and metastasis. It has now been discovered that certain compounds inhibit the signal transduction required for the maintenance and driving of the malignant process. These compounds are also effective for the in vivo treatment of solid tumors and related disease states. This invention provides a method for the use of these compounds to inhibit the invasion and metastasis of malignant solid tumors in mammals. This invention further provides a method for using related compounds to treat diseases involving aberrant signal transduction pathways. Some of the compounds used in the methods of the present invention are novel and constitute another aspect of this invention.
