Abstract: A method for positioning excitation pulses for a linear predictive coder (LPC) operating according to the multi-pulse principle, i.e. a number of such pulses are positioned at specific time points and with specific amplitude. The time points and the amplitudes are determined from the predictive parameters (ak) and the predictive residue signal (dk), by correlation between a speech representative signal (y) and a composed synthesized signal (y/< ANd >). This can provide all possible time positions for the excitation pulses within a given frame interval. According to the proposed method, the possible time positions are divided into a number (nf) of phase positions and each phase- position is divided into a number of phases (f). These phases are vacant for the first excitation pulse. When this pulse has been positioned, the phase determined for this pulse is denied to the following excitation pulses until all pulses in a frame have been positioned.

Abstract: A cationic resin containing blocked isocyanate groups which is suitable for use in electrodeposition is disclosed. The cationic resin is derived from an epoxy resin and contains in the resin molecule cationic salt groups, active hydrogen groups and blocked isocyanate groups. The blocked isocyanate groups are incorporated into the resin molecule by reacting the epoxy resin with a compound selected from the class consisting of mercapto compounds and acid group-containing compounds where the compounds also contain blocked isocyanate groups. The resin can be formulated into an electrocoating composition which is free of lead and yet provides outstanding corrosion resistance when electrodeposited over steel substrates. The outstanding corrosion resistance can be attained when the substrate has not been given a chrome rinse which is conventional in pretreating the steel substrate before electrodeposition.

Abstract: A flexible and substantially non-resilient package (1) containing a number of three-dimensional objects (50). The package is such that multiple packages are stacked on top of one another. The package includes a flexible substantially rectangular container (2) comprising opposing top and bottom walls (10, 11) and two pairs of opposing side walls (12, 13, 14, 15), all of which are joined together to form an interior chamber (3) for containing the non-rectangular objects. The three-dimensional objects to be contained, such as soap bars, are substantially rigid and non-rectangular. The objects have two non-planar opposing oblong faces (51, 52). The faces are connected by a pair of opposing major peripheral edges (53, 54) and a pair of opposing minor peripheral edges (55, 56) with the minor peripheral edges being smaller than the major peripheral edges. The objects are placed within the container in face to face relation with the major and minor peripheral edges of each object being parallel. The objects are constrained within the package so that movement of the objects with respect to one another and with respect to the container is substantially limited. Thereafter, multiple packages can be stacked on top of one another with the objects resting on their minor peripheral edges and the load of the objects can be transmitted through columns of stacked objects.
