Patent CA-2156558-A1 (CA)
Inventor: HAAGEN JESPER
IPC: G10L19/00
Filed: 1995-08-21
Abstract: A method and apparatus which allows the transmission of the perceptually important features of a speech-coding parameter at a low bit rate. The speech coding parameter may, for example, comprise the signal power of the speech. The parameter is processed on a block by block basis. The parameter value at the block boundaries is transmitted by conventional methods such as, for example, by means of differential quantization. The shape of the reconstructed parameter contour within block boundaries is based on a classification. The classification determines perceptually important features of the parameter contour within a block. Based on the result of the classification as well as the parameter values at the block boundaries, a parameter contour (within the block) is selected from an inventory of possible parameter contours.

Abstract: The use of FDA acceptable rubbers has been known for years.  This endless belt is for use on meat deboning equipment where the well known endless belts in use are modified by applying a fiber reinforced layer to the belt to improve the belts' life and yield of deboned meat.  This belt allows easy cleaning of the belt and equipment.  A conventional FDA acceptable deboning belt, such as a woven fabric, e.g. nylon rubberized with a rubber compounded with FDA acceptable materials is modified by applying during manufacturing a special cover stock.  This special cover stock is a blend of a polyaramid pulp or very short fibers of a polyaramid with polychloroprene to give a blend of about 2 to about 8 percent by weight of polyaramid.
