Abstract: The folded thermoplastic filter element for mounting between inlet and outlet is mfd. such that the folds open to the outlet side are held apart by oblong, embossed portions (15) formed in the material. The material web forming the element is transported in its longitudinal direction is first pleated in the transverse direction for the amount necessary to form the embossed portions. The latter are produced by stress-free permanent shaping, with the material heated to above shaping and below shrinkage temp. between jaws. Then it is cooled below the shaping temp. The linear folds are formed by jaws heated to between shaping temp. and melting point until all unevenness is smoothed out and then cooled again.

Abstract: Titanium, magnesium or zirconium calcium oxide is formed by a process which involves the transfer of the reaction product from an autoclave 10 to a receiving vessel 12 at a substantially constant flow rate. Just prior to this transfer, the pressure in the receiving vessel 12 is brought up to the pressure in the autoclave 10 by passing gas from the autoclave to the receiving vessel. The flow of gas from the autoclave to the receiving vessel 12 is then stopped, and the pressure in the receiving vessel is allowed to drop due to transfer of heat from the gas to the walls of the receiving vessel. The resulting pressure difference between the autoclave 10 and the receiving vessel 12 is used to initiate the transfer of the reaction products from the autoclave to the receiving vessel. A pressure release valve 12d on the receiving vessel is then controlled by means of a signal derived from a flow meter 13 which measures the flow rate of the reaction products flowing from the autoclave 10 to the receiving vessel 12 to maintain constant this flow rate.

Abstract: The present invention relates to a tool for cutting solid material, said tool including a tool body (10) having a recess (12) and a cutting insert (11) having spacing means (21), said cutting insert (11) being received in said recess (12) and secured to the tool body (10) by brazing. 
     A frequent problem when securing a cutting insert to a tool body by brazing is to fix the cutting insert in a correct position relative to the tool body before brazing alloy is introduced between the cutting insert and the tool body. If the cutting insert has a tilted position when brazing is effected, the brazing joint will have an uneven thickness. This in a negative way affects the ability of the brazing joint to absorb forces and turning moments. 
     The present invention is characterized by supporting means (17) in the recess (12), said supporting means preferably being in the shape of an annular groove (17) and adapted to receive the spacing means (21).

Abstract: In automatic speech recognition it is usual to make a spectral analysis of the incoming speech signal and it can be useful to detect the frequencies and intensities of the formants. However although the formants are mostly quite well defined during vowel sounds there are frequent occasions when this is not so and it is not so during a high proportion of consonant sounds. The present invention determines the frequencies at which the centroids of respective frequency versus power distributions occur in a plurality of frequency bands of a signal representing speech (approximately corresponding to the ranges of individual formants). The centroids have most of the desirable properties of formants but also carry significant information for those sounds for which the conventional definition of formants does not seem appropriate. Preferably the powers in the bands in which the centroids are measured are also determined. The incoming signal is filtered (2) into separate frequency bands and the power in each band is measured (4). The output signal in each band is weighted by 3 dB per octave (5) and then the power in that band is measured (6). The power ratio obtained (7) for a band from the power after 3 dB weighting divided by the power before weighting gives an indication of the position of the centroid of that band in the frequency spectrum.

Abstract: A method is described for determining the axial variation, in particular the bending, of an elongated, preferably round or concentrically symmetric object, such as, for example, rods, shafts, drills and the like. In this method, the body is clamped in a clamping device, preferably the chuck of a lathe, and is measured at the clamping point and other points of the rod axis (z axis). The pertinent x, y coordinates of the rod axis and the obliqueness or bending of the axis are analytically determined from the parameters measured by an dial gauge. These coordinates and the obliqueness or bending represent a measure of acceptance in quality assurance. <IMAGE>
