Abstract: A method and an apparatus for handling incoming calls when call waiting is active. If the called party is not on a call when an incoming call occurs and the called party does not answer the incoming call then a message is played to the calling party that the called party did not answer, and the called party is given the opportunity to record a message for the called party. If the called party is on a call when an incoming call occurs and, after the call waiting signal is played to the called party, the called party does not answer the incoming call then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. If the called party is engaged in a first call and a second call when an incoming call occurs then a message is played to the calling party that the called party is busy, and the called party is given the opportunity to record a message for the called party. Therefore, even when call waiting is active, the calling party is properly advised of the reason that the called party did not answer the incoming call.

Abstract: A hydrometallurgical process is provided for producing pigment grade TiO2 from titanium containing solutions.  Generally, the solution is an aqueous solution. The process includes hydrolyzing the solution via complete evaporation in well-controlled conditions of temperature to form titanium oxide of well-defined characteristics. The hydrolyzing can be achieved by spray hydrolysis in a spray dryer. After hydrolyzing, the titanium oxide is calcined to transform the titanium oxide to the desired form of titanium dioxide. The titanium dioxide can be either anatase or rutile. Following calcination, the titanium dioxide is milled to provide the desired particle size distribution and then finished.

Title: Dual riser/single capillary viscometer
Inventor: KIM SANGHO
IPC: G01N33/15
Filed: 2000-10-12
Granted: 2005-04-26
Abstract: A blood viscosity measuring system and methods for measuring blood viscosity monitors the change in height of two, oppositely-moving, columns of blood from the circulating blood of a patient and, given the dimensions of a capillary tube through which the blood flows, determines the blood viscosity over a range of shears, especially low shears.      The system includes a tube set (disposable or non-disposable) that includes a pair of riser tubes, a capillary tube of predetermined dimensions that is coupled between the riser tubes (or that forms a portion of one riser tube) and a valve mechanism for controlling the circulating flow of blood from the patient into the riser tubes. Respective sensors monitor the movement of the columns of blood in each of the riser tubes and an associated microprocessor analyzes these movements, along with the predetermined dimensions of the capillary tube to determine the viscosity of the patient's circulating blood. An alternative system and method monitors only one of the two oppositely moving columns while detecting a single height position of the other one of the moving columns. From that data, along with the dimensions of a capillary tube through which the blood flows, the blood viscosity over a range of shears, especially low shears, is determined.

Title: Citrus fruit segmenter
Inventor: HOLCOMB DAVID A
IPC: B26D3/26
Filed: 2003-08-12
Granted: 2007-12-04
Abstract: A single-handedly operated citrus fruit segmenter having first and second arms such that squeezing the arms into a closed position causes a curved movable scoop to extend into a citrus fruit proximate to a triangular blade and form a segment-shaped compartment. The actuation of the curved movable scoop occurs by a user squeezing the first arm toward the second arm. A pin on the first arm is operatively connected to an elongated slot of a cam mechanism such that the rotation of the first arm about its pivot location causes the cam mechanism to rotate about its own pivot location. Therefore, the cam mechanism, being also connected to the carved movable scoop, forces the curved movable scoop into the citrus fruit.
