Title: Process for the work-up of complex amine hydrofluorides
Inventor: HAHN ULRICH
IPC: C07C17/087
Filed: 1995-12-19
Abstract: The invention relates to a process for the work-up of a liquid complex hydrofluoride of a tertiary amine of the formula (I)  [R1R2R3Nn HF], where the radicals R1, R2 and R3 are C1-C8-alkyl groups which together have at least 7 carbon atoms and n is an integer or fractional number where 1.5 < n < 3, which, for the purpose of molecular addition of HF to a halogenated alkene, is reacted with the latter. In the reaction of the halogenated alkene with the complex amine hydrofluoride of the formula (I), the molar ratio HF:R1R2R3N is allowed to fall until amine separates out as a further liquid phase, and the amine is separated off.

Abstract: An air-fuel ratio control system which calculates a basic injection amount of fuel by state detecting sensors each of which detects an operating state of an internal combustion engine, air-amount detecting sensors each of which detects an intake air amount, an air-fuel ratio sensor, and a predetermined data group. Further, the air-fuel ratio control system stores past amount data of injected fuel and air-fuel ratio data at each control cycle. A neuro-computation unit reads values of the data detected by the sensors and the stored data to obtain an air-fuel ratio estimate to calculate a correction injection amount of fuel by a neural network of a forward neuro-computing unit, which has learned beforehand about relations of the injected fuel amount, the detected air-fuel ratio, parameters, and dead time.

Abstract: A method and apparatus for performing vector quantization in a video coder is disclosed.  The method includes obtaining a video frame and segmenting it into coding blocks of predetermined size.  A predetermined number of the coding blocks is transferred to a first cache memory.  A predetermined portion of a codebook is transferred into a first section of a second cache memory which is capable of being rotated or having addresses associated with bytes in the second cache memory interchanged or offset by a specified amount. Concurrently with computing the vector quantization for the first portion of the codebook with respect to the coding blocks in the first cache memory, a second section of the codebook is transferred into a second section of the second cache memory.  The number of coding blocks transferred to the first cache memory is selected so that transferral of the second section of the codebook is completed at the same time as or prior to completion of the computation of the vector quantization.  The second cache memory may be rotated so that the process may be repeated for the remaining sections of the codebook with minimal or no delay, thereby permitting vector quantization to be performed in real time video coders.

The dive-stop structure includes a passage defined by the body that extends through at least a portion of the body, with the passage having a first end proximate the front region of the body and a second end of the upper surface. The fishing weight further includes a pair of wings connected to the body and extending in generally opposed directions outwardly and upwardly from the rear portion of the body toward the front portion and the upper surface to define a wing plane. The fishing weight has a center of gravity bounded generally by the wing plane, and the center of gravity and wing plane cooperate to predispose weight to dive at a pre-determined angle. The fishing weight is also formed from a novel polymer-based composite material consisting essentially of a first volume of a curable polymeric component mixed with a second volume of iron ferrite particles, such that the unit has a specific gravity of about 7.5-8.0, with the unit including a central substantially uncured section and an outer substantially cured section.
