  • Patent number: 9238777
    Abstract: A method for producing compounds of formula (I) in which the radical R1 is selected from —NH2, —NH2-zAz, and monovalent alkyl and aryl radicals, the radicals A are selected in each case independently of one another from the phosphoryl radicals DOPO-, DPhPO- and DPhOPO-, and the indices x, y and z, in each case independently of one another, stand for 0 or 1, wherein at least one of the indices is ?0, by reacting, in a first step, melamine or, when R1 is an alkyl or aryl radical, the corresponding alkyl or aryl guanamine, with one or more of the corresponding phosphinyl chlorides DOP-CI, DPhP-Cl and DPhOP-CI, in order to bond one or more phosphinyl radicals to the amino groups(s) of the melamine or guanamine, and in a second step oxidizing the phosphinyl radical(s) by reaction with an oxidizing agent to give the corresponding phosphoryl radical(s).

  • Patent number: 9174290
    Abstract: A motor unit has a tool for engaging a work piece with a frame unit, which has a gripping element for the handheld operation of the device, wherein a mechanical coupling is provided between the motor unit and frame unit, which encompasses at least one dampening element, in such a way that makes it possible to precisely guide the tool while improving the dampening of vibrations between the motor unit and frame unit. The frame unit has at least one abutting element, against which the motor unit abuts when a working force exerted by the work piece on the tool has a value below a minimum value.
