  • 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: 7412961
    Abstract: To improve an intake device (100) for a handheld tool implemented having an air cleaner, particularly for a chainsaw, a cuffing-off grinder, or the like, which comprises an internal combustion engine (25) and a drive unit (20) for the attachment, the air cleaner cleaning combustion air, which is charged with dirt particles, for the engine (25), in that a centrifugal separator (30) separates the combustion air into at least one first air flow (31), which is freed from dirt particles as much as possible, and a second air flow (32), which is loaded with dirt particles, in particular to cause higher efficiency of the intake device, it is suggested that a blower (10) be situated on the drive unit (20), which sucks in the second air flow (32), by which cooling of the drive unit (20) is caused.

  • Publication number: 20050155594
    Abstract: This invention entails a guide device, especially for use with abrasive cutting-off machines, which has at least one rolling means for rolling the guide device substantially by the body power of a user. The guide device has at least one handle arranged opposite the rolling means for transferring a force exerted by the arms of the user onto the handle. The device is characterized by a pushing element for transferring a force exerted by another body part of the user, in particular the thigh, onto the guide device.
