IPC: A23K50/15
Filed: 1984-11-13
Abstract: A process for the preparation of 2-hydroxy-4-methylthiobutyric acid having improved color, odor and lower viscosity. 2-hydroxy-4-methylthiobutyronitrile is hydrolyzed with sulfuric acid having an initial strength of between about 50% by weight and about 70% by weight on an organic-free basis, thereby producing an intermediate aqueous hydrolysis product solution containing 2-hydroxy-4-methylthiobutyramide. The 2-hydroxy-4-methylthiobuty- ramide is hydrolyzed with sulfuric acid having a strength of between about 30% by weight and about 50% by weight on an organic-free basis to produce an aqueous hydrolyzate containing 2-hydroxy-4-methylthiobutyric acid. The hydrolyzate solution is contacted with a substantially water-immiscible organic solvent in a liquid-liquid extraction system to produce an extract comprising the solvent and 2-hydroxy-4-methylthiobutyric acid transferred from the hydrolyzate. The acid product is then recovered from the extract.

Title: Vacuum cleaner housing and dust bag
Inventor: JACOB GERNOT
IPC: A47L9/14
Filed: 1985-10-11
Abstract: A vacuum cleaner housing possesses two guide means on the inner side of the end housing wall with a suction port therein in order to receive the board flange of a dust bag adjacent to the lateral housing wall. The guide means comprise guide rails each with a ramp-like wall, extending towards said housing wall, and guide ribs which are located in the lower part of the housing wall and have a slope opposite to that of the ramp-like walls. They are so shaped as to allow the board flange to be inserted between them and the walls. On introduction of such a board flange of a dust bag its lower end section is bent along a prepared line of bending, which has been formed in the lower part of the board flange parallel to its lower side. Accordingly the board flange is so firmly held in place that it is not bent by the suction force to which it is exposed. The vacuum cleaner housing is further made with a cover stop which prevents closure of the cover unless a dust bag has been previously placed in the vacuum cleaner housing.

Abstract: A digital video signal processing circuit generates non-interlaced lines of video information ("progressive scan") from interlaced composite color video signal including a luminance signal which contains vertical detail inform- tion without peaking. There are two progressive scan speed-up processors (PSP1,PSP2) functioning in parallel and controlled to operate alternately, the one in a reading mode and the other in a writing mode, and vice versa. Each receives the interlaced luminance and chrominance signals. In each of the speed-up processors, a line of chrominance signals (I,Q) is time compressed and repeated to generate two lines (1"  2x , I"  2x  or Q"  2x , Q"  2x ) of time compressed chrominance video for each line of interlaced chrominance video (Figure 3j,k). Furthermore, in each of the speed-up processors, a vertical detail signal (Y"  D ) is regenerated that contains vertical detail information derived from the interlaced luminance signal (Y). The vertical detail signal is nonlinearly processed (57) to generate a vertical peaking signal (Y"  P ) that is combined (58) with the vertical detail signal. A time compression stage (60b) speeds up the peaked vertical detail signal (Y; + YP) to a double line rate (Y"  2xV ). Another time compression stage (60c) speeds up a luminance signal (Y"  cm ) containing high frequency information. The time compressed peaked vertical detail signal and the time compressed high frequency luminance signal are combined (59, MUX2,62,61) to generate a time compressed enhanced luminance signal, such that alternate lines (Y"  2x- ,Y"  2x+ ) of the enhanced luminance signal contain vertical peaking information of opposing polarities. The outputs of the two speed-up processors are multiplexed (MUX1, FIG1) and applied to a color matrix (37) to generate the time compressed lines of noninterlaced red, green and blue signals.

Abstract: In a railway vehicle safety system, a frequency modulated signal is transmitted to a vehicle informing, inter alia, of a safe maximum speed, the said speed being represented by the carrier modulation frequency. In addition, the frequency of the carrier may possess one of a number of alternative frequencies. Apparatus for analysing received signals to identify the carrier frequency and the modulation frequency employs a fast Fourier transform processor. In order to save computation time by eliminating useless calculations, a received signal is heterovdned bv a local signal selected accordina to the carrier frequency identified and the base-band components are analysed to identify the modulation frequency. A first stage transform is performed to identify the carrier signal and select the local signal frequency for a complex heterodyne process in a second stage in which local signals in phase quadrature are mixed with the received signal and the results sampled to provide data for real and imaginary data arrays for the transform process. As a result of the second stage process, noise and common mode interference signals are rejected.

Abstract: An automatically adjustable roller bearing assembly 3 includes two sets of tapered rollers 9 between a dual track oppositely tapered inner race 5 and a pair of single track tapered outer races 7. Each outer race 7 is in communication with a coaxial, hydraulically loaded annular ring 11 which is axially movable in an annular piston cylinder 15 supplied with hydraulic fluid. The hydraulic pressure of the fluid is maintained through an accumulator 18 at a preselectable constant pressure to permit the outer races 7 to translate axially, against the annular rings 11, as the inner race 5 expands radially due to thermal expansion. Upon thermal contraction, the hydraulic pressure forces the annular rings 11 in the opposite directions to reduce the clearances which would otherwise have been created. The assembly 3 is also useful in compensating for wear.
