Patent CA-2536322-A1 (CA)
Inventor: STOLLER JERRY H
IPC: A01N43/12
Filed: 2004-08-18
Abstract: In agriculture when temperature and moisture deviate from the norm two things happen, plant growth suffers and disease flourishes. The Stoller model for plant growth states that proper hormone balance is necessary for optimum growth and performance. When growth conditions deviate from the norm, hormone balance is altered and plant growth suffers. This invention presents evidence to support this model and explain the relationship between hormone levels and plant growth. A clear understanding of this relationship will facilitate crop treatments aimed to eliminate these problems. Although we cannot control the climate, we can control the damage caused by environmental stresses by manipulating the levels and/or ratio of plant hormones in the different plant tissues. By adjusting the levels and/or ratios of hormones, particularly auxin and cytokinins in the root tissue, we can assist the plant in overcoming or compensating for this environmental stress.

Title: Method of treating strongly acid wastewater containing toxic substances
Inventor: KAKINUMA SYUZO
IPC: C02F1/28
Filed: 2004-03-31
Abstract: A method of treating a strongly acid wastewater containing a harmful substance. By the method, harmful substances such as fluorine, boron, copper, lead, arsenic, hexavalent chromium, and cadmium can be safely removed from wastewaters without fail. The method, which is for treating a strongly acid liquid (1A) containing a harmful substance, comprises conducting the following steps in this order: an adsorption/precipitation step (S1) in which hydroxyapatite (11) is mixed with the strongly acid liquid (1A) to precipitate the harmful substance as a solid matter; a neutralization step (S2) in which an alkaline substance (12) is mixed with the treated acid liquid (3A) containing the solid matter precipitated to neutralize the liquid (3A); and a coagulation step (S3) in which the treated liquid (4A) which has been neutralized is mixed with a coagulant (13) to coagulate the solid matter precipitated. The harmful substance in the strongly acid liquid (1A) can be effectively fixed and can be removed in a safe form. The concentration of the harmful substance in the liquid can be lowered through the treatment. There is no need of heating the liquid in each step and the treatment can be carried out at ordinary temperature. The harmful substance can hence be treated safely.

Title: Ring control circuit based on ring pattern discrimination
Inventor: XU JIAN PHOENIX
IPC: H04M1/00
Filed: 2006-10-11
Abstract: This low-cost circuit functions in conjunction with and improves the distinctive ring service provided by telephone companies. Distinctive ring service allows a primary telephone number and an additional telephone number share one telephone line.  The additional number corresponds to a distinctive ring pattern different from the common one. This circuit controls the connection between the telephone line and the telephone subscriber equipment in the duration of every burst of ring signal on the basis of discriminating the pattern of the ring signal. Therefore, this circuit makes it achievable, that when either one of the two telephone numbers is dialed, only the subscriber equipments designated to that number ring, while the ones designated to the other number remain silent, although the two numbers share one telephone line. Another function of this circuit is busy-line indication. Furthermore, the power consumed by this circuit comes from the telephone line.
