Title: Desalting aqueous streams via filled cell electrodialysis
Inventor: MANI KRISHNAMURITY N
IPC: C13B20/18
Filed: 1998-11-19
Abstract: The invention is a process for desalting aqueous solutions, which are initially acidified to a pH of about 3 or less. Then, the acidified solution is fed into a desalting compartment of an electrodeionization cell which contains a suitable ion exchange material and is isolated from an adjacent concentrating compartment by an anion and a cation exchange membrane. The concentrate compartment contains a netting or another suitable material that promotes turbulence in a flowing feed stream. Water is supplied to the concentrate compartment. A DC current passes through the electrodeionization cell to produce a substantial desalination of the feed solution. A less acidic desalted solution and a concentrate waste solution are withdrawn from the electrodeionization cell.

Title: Method and apparatus of power control in a cdma dispatch system
Inventor: LEKVEN ERIC J
IPC: H04B7/26
Filed: 1997-06-06
Abstract: In a dispatch system, power of the forward link broadcast channel transmitted from a base station is controlled such that the power level is the minimum necessary and such that transmission of the forward link broadcast channel is terminated if no remote unit (10) is Located within the coverage area of the base station (32). In addition to transmitting a forward link broadcast signal, the base station monitors an access channel.      A first remote unit (10) in the base station coverage area receives and decodes the forward link broadcast signal. The first remote unit (10) determines a signal quality of said forward link broadcast signal. If the signal quality is unacceptable, the remote unit transmits a power request access message. The base station responds to the request by increasing the transmission power of forward link broadcast channel (70). If no requests are received at the base station, the forward link broadcast channel is slowly decreased to a minimum (54). Transmission of the forward link broadcast channel may be terminated completely (58).

Inventor: SMITH THOMAS
IPC: G01N9/00
Filed: 1997-10-07
Abstract: A densitometer (10) includes a gas sample plenum (40) that is connected to a gas supply pipe (26) via a flow-restricted inlet duct (42) to at least partially isolate and damp the sample plenum (40) from shocks and noises, turbulences, and abrupt pressure changes in the gas supply. A cantilevered vane (110) is positioned in the sample plenum (40) for gas density determinations on the principle that resonant frequency of the vane (110) is a function of the density of the gas in the sample plenum (40). The resonant frequency of the vane (110) in the gas is determined by applying a magnetic field generated by a driver assembly (120) against the vane (110) and detecting the resonant frequency with a vibration detector (117), which is connected to the driver assembly (120) in a phase locked loop.
