Title: Process for manufacture of lithium hexafluorophosphate
Inventor: BONNET PHILIPPE
IPC: C01D15/00
Filed: 1998-06-05
Granted: 2001-02-21
Abstract: The process of the present invention consists in bringing into contact, on the one hand, (A) gaseous phosphorus pentafluoride or a gaseous mixture comprising phosphorus pentafluoride and hydrochloric acid, and, on the other hand, (B) a solution of lithium fluoride in hydrofluoric acid, in a column (10) having a sufficient number of transfer units to carry out the reaction of PF5 with LiF under the chosen conditions of temperature, of pressure and of molar ratio of the two contrasting reactants and with complete or substantially complete absorption of the PF5 in the column. This process makes it possible to solve the problems of blockage by preventing recrystallizations of salts; to discharge the heat given off by the reaction by the evaporation of a portion of the HF; and to separate the HC1 which may be contained in the starting PF5, without loss of PF5, thus allowing subsequent recovery/value enhancement of this HC1. Moreover, this process is very simple, with a very small number of stages, which makes it possible to avoid any entry of air or moisture capable of contaminating the final LiPF6.

Title: Hybrid image-reject receiving apparatus and method
Inventor: HUANG JIA-CHI
IPC: H04N1/38
Filed: 1999-05-15
Granted: 2001-02-01
Abstract: A novel hybrid image-reject receiver architecture is disclosed. We first modify Hartley image-reject receiver and obtain two output signals which both consist of a desired signal and an image signal. One output signal contains a stronger desired signal and a weaker image signal and the other output signal contains a stronger image signal and a weaker desired signal. The two output signals are then sent to a digital desired/image signal separator to obtain a baseband output signal. The IRR of this baseband output signal is the cube of the IRR obtainable by a Hartley image-reject receiver. At the same time, we can cascade multi-stages of the desired/images signal separators to achieve further gain on IRR. The architecture greatly enhances the image rejection ratio (IRR) and relaxes the requirements of matching for analog devices.
