Abstract: Toner particles for electrophotographic copying and electrostatic printing consist of pigmented thermoplastic base particles having the surface covered with a thermoplastic fine-grained polymerizate. The base particles are prepared by suspension polymerization and the fine-grained polymerizate originates from a latex prepared by emulsion or microsuspension polymerization. One method of preparing the toner consists of bringing an aqueous dispersion of the base particles into contact with a latex of the fine-grained polymerizate. The temperature is raised so that the fine-grained particles adhere to the surface of the base particles. A protective colloid system can be present and the particles can have charges of opposite character. In another method the preparation of the toner particles comprises suspension polymerization of monomer for formation of the base particles in the presence of an already prepared latex whereby the latex particles have higher hydrophilicity than the polymer in the base particle.

Abstract: In a liquid scintillation counter the light output from a liquid scintillation sample containing radioactive isotopes of unknown activity is measured by means of a detector. A pulse height analyzer having discriminators that are combined to define pulse height windows, is connected to the detector for measuring and temporarily storing count rates for each of the windows. Moreover, there are means for determining a value for the quench level of the sample. According to the invention the number of pulse height windows is at least N+1, when the number of isotopes is N,N being .gtoreq.2. There are memory means for storing for each of said windows representations of counting intensities determined by measuring calibration samples of each isotope at different levels of quench.

Abstract: In an electrically operated valve, a valve closure member, which lies in the path between the inlet channel and the outlet channel, is connected to an expansion member. At the time of electrical heating, the expansion member lifts the valve closure member from the associated valve seat, due to which the path for the flowing medium is cleared. A cooling member is located in an annular channel, into which, controlled by a regulating valve, different quantities of flowing medium can be introduced. The cooling member is thermally coupled to the expansion member. In this way, the expansion member, according to the position of the regulating valve, can be cooled to different degrees, due to which the response behaviour of the valve is variable in particular after switching-off the electric current.

Abstract: The invention comprises a road cutting equipment for cutting grooves, or slots in road surfaces and comprises an apparatus attached to an end of a vehicle.
