Patent DE-2536640-A1 (DE)
Inventor: BUNGE ERNST DIPL ING
IPC: G10L15/00
Filed: 1975-08-16
Abstract: Sounds or speech signals are converted into an electrical sound and broken down into separate spectral components in a filter bank. These components are integrated over a short period of time and produce a short-time spectrum of the signal. The spectal components are applied, via a corresponding number of parallel leads, to a number of pattern detectors which supply an output signal only if the short-time spectrum corresponds to the pattern adjusted in the relevant pattern detector. To this end, each pattern detector includes two threshold value (window) detectors which supply a signal if the applied input signal lies between two adjustable thresholds. Each threshold value detector is connected to a different output of the filter bank for another spectral range and is generally adjusted to different threshold values. The outputs of the threshold value detectors are combined via an AND-element, so that a signal is produced only if all threshold value detectors of the pattern detector are activated. For each sound or for each phoneme in the case of speech, a pattern detector is provided. When series of sounds or signals are recognized, the series of addresses of the pattern detectors which have successively generated an output signal are stored and subsequently applied to the computer for comparison.

Filed: 1975-09-19
Abstract: Drum fitler for filtering slurries and producing shaped pieces from the filter cake consists of a rotating drum partly immersed in the slurry having a lattice formed band contacting it in the suction region. The cake forms in the spaces of the lattice and is taken away by the band. The band is run around a roller and on the lower run between the drum and the roller is a pronged roller to discharge the cake from the lattice. The prongs are of the same shape and pattern as the lattice having a height which is slightly less than the depth of the lattice. The surface of the roller is made from elasticated material such as plastic foam which presses into the lattice slightly as it passes over. Esp. for use in filtering iron ore, the cake briquettes so formed being subsequently sintered. In existing equipment, the briquettes fall into a chute where they can be damaged, causing fires which must then be recovered from the sintering process. The system described gives a simple means of releasing the briquettes from the lattice and transporting them away without damage.
