Abstract: For rotor control in thin-film driers or thin-film evaporators with scraper elements mounted movably, pivotably or elastically on the rotor for the removal of product deposits on the rotor surfaces or on the inner walls during operation, the preselected nominal speed of the rotor is varied by appropriate switching devices during operation and subsequently, if appropriate after a preset period, the rotor is brought back, especially abruptly, to the preselected nominal speed or another preset speed. Preferably, the nominal speed is varied as a function of unit parameters representing a measure of the formation of deposits in the unit, especially on the rotor or on the inner wall. <IMAGE>

Inventor: SCHLAG EDWARD PROF DR
IPC: H05H3/02
Filed: 1988-07-19
Abstract: During the evaporation of a sample substance consisting of large molecules, in particular for mass spectroscopy investigations, the energy supplied for the evaporation can bring about a thermolytic decomposition of the sample substance. According to the invention, in order to prevent such a decomposition, the sample substance is mixed, before irradiation, with a matrix material which consists of a compound which readily decomposes into gaseous molecules on exposure to the laser beam. This material may be one which absorbs the radiation, readily decomposes thermolytically or, alternatively, is transparent to the laser radiation but is mixed with a metal powder. If the mixture is exposed to laser beam pulses, the unstable matrix material first decomposes and thereby releases the embedded molecules of the sample substance. In particular, in combination with a cooling gas jet, a destruction of the molecules of the sample substance can be avoided almost completely in this way. Suitable compounds for the matrix are, in particular, sugar, cellulose and NH4NO3, and polyethylene with gold or silver dust added.

Abstract: A musical tone signal generator for an electronic musical instrument is constructed by a waveshape generator (13,14), a function generator (16) and an interpolator (18, 19, 20). The waveshape generator (13, 14) successively generates adjacent two waveshapes of a plurality of dif­ferent waveshapes which have been intermittently sampled in an actual produced tone. The function generator (16) generates an interpolation function which is a function of time. The interpolator (18, 19, 20) weights the adjacent two waveshapes in accordance with the inter­polation function, combines the weighted two waveshapes and outputs the combined waveshape as a musical tone waveshape to be produced at a rate corresponding to a frequency of the musical tone waveshape. In the waveshape generator (13, 14), the generation of next two adjacent waveshapes are performed when a value of the interpolation function has become equal to a predetermined value. As a result, it is made possible to obtain a good quality timewise spectrum change of the musical tone waveshape.
