Title: Method and apparatus for coding digital signals
Inventor: BEYROUTI MICHAEL GEORGE
IPC: G10L19/04
Filed: 1984-10-08
Granted: 1989-06-08
Abstract: In a method and apparatus for coding of digital signals, especially so-called "waveform" coding of voice frequency signals to reduce bit rates for reduced transmission or storage requirements, in which, for each block, an excitation signal is derived which, when applied to be a synthesis filter having suitable LPC coefficients, will generate an approximation to the input signal, low signal delay is achieved by deriving such excitation signal using the LPC coefficients corresponding to the last sample period of the corresponding block. Thus the excitation signal calculations in the encoder need only be delayed by the duration of the block. The LPC coefficients can be derived on a continuous or sample-by-sample basis using an adaptive lattice. Simplified computation of the excitation signal, which comprises a set of pulses fewer in number than the number of samples in the original block, may be achieved by cross-correlating the impulse response of the modified synthesis filter with the output of the filter and using the result, together with the covariance of the impulse response, to derive the parameters of the excitation pulses. Further computation simplifications may be achieved by using an auto-correlation as the covariance signal.

Abstract: An enhancer for eukaryotic expression systems contains DNA from the upstream region of the major intermediate early (IE) gene of human cytomegalovirus (HCMV). The enhancer is made by treating DNA from the specified region with sound to generate approx. 300 bp fragments. These are used for co-transfection of CV1 ape cells and enhancer-free SV40 qenome and then recombinants which show lytic growth are isolated. The inserted HCMV-DNA, and its enhancer-active mutants, are recovered. Specifically, the fragments obtd. are 341 and 262 bp in size (corresponding to positions -118 to -458 and -263 to -524), and the overlap region contains the essential portion of the enhancer.

Abstract: The present invention relates to novel antibody heteroconjugates and their use in methods for killing HIV-infected cells. The heteroconjugates are comprised of an antibody specific for an HIV antigen that is expressed on HIV-infected cells cross-linked to an antibody specific for an effector cell of the peripheral blood capable of killing an HIV-infected target cell. The antibody heteroconjugates of the invention physically bridge the effector cell to the target cell and may activate the lytic mechanism of the effector cell in the killing of the HIV-infected target cell. The methods, heteroconjugates, pharmaceutical compositions and combinations described herein provide a novel approach to the treatment of HIV-infected individuals by amplifying endogenous HIV-specific effector mechanisms and may also be of prophylactic value in individuals newly infected or accidentally exposed to the HIV virus.

Abstract: A method of producing shaped, self-supporting ceramic bodies includes preparing a mold by applying a permeable, conformable material (5) to a shape-defining surface (3) of an expendable pattern (2). The permeable, conformable material, when set or stable, provides a mold with a shaped surface which is defined by, and is therefore substantially congruent to, the shape-defining surface. Upon heating, the material of the expendable pattern (2) combusts or volatilizes and thus establishes the shaped cavity mold. A molten parent metal (1) is then vaporized with a vapor-phase oxidant in such a manner as to form a ceramic body which grows into the mold cavity, and is shaped by it. The ceramic body is recovered from the mold having a shaped surface replicating the shape-defining surface (3) of the expendable pattern (2).
