Patent CA-2245395-A1 (CA)
Inventor: LIU LIQING
IPC: F42C21/00
Filed: 1998-08-20
Abstract: This invention provides a method and electronic circuits for the testing of new initiation devices that use a small transformer whose heating element resistance can not be measured using traditional methods and instruments. A small current testing signal is applied to the primary winding of the detonator through its leg wires that are connected in a certain circuit configuration. The resistance of the secondary winding connected with the bridge wire is then reflected to the primary side and its effects are then observed. By calibrating the relationship of such effects with the value of loop resistance, the loop resistance can he displayed. Since the testing signal is very small in nature for safety considerations, the sampled effects (generally the voltage wave) are amplified. The amplified effects are displayed with analogue or digital meters or other display means.

Title: Modified cytokines for therapeutic use
Inventor: DELLABONA PAOLO
IPC: A61K47/48
Filed: 1997-02-14
Abstract: The object of the present invention is a new method and new products for the therapeutic use of cytokines. The method is based on the sequential administration of a component A (e.g. a biotinylated antibody) able to deliver onto a particular pathologic target a second component B (e.g. avidin), followed by a component able to bind the component B (component C) (e.g.  biotin), conjugated with the cytokines. The method permits to increase the local concentration of the modified cytokines (C-cytokines) through the interaction with the "artificial" receptor B and to cause a local biologic response mediated by "natural" receptors.

Title: Method and mechanism for a task oriented data model
Inventor: LAU CHRISTINA P
IPC: G06F9/45
Filed: 1998-11-30
Abstract: A task oriented data model for an object oriented development tool. The data model comprises a task oriented structure which mirrors the task tree embodied in the user interface of the development tool. The object development tool exports and imports the data model as a document file expressed in a open standard language such as XML. The data model comprises a series of data elements which are arranged to mirror the user interface according to a meta data model. The meta data model is implemented in XML as a Document Type Definition and comprises containment relationships defined by XML constructs. By making the user interface implicit in the organization of the data model, the data model can be imported by another tool by simply following or scripting the data structure, and the data model is validated when the import utility loads the document file by comparing the data model to a meta data model specified in the Document Type Definition.

Patent CA-2267028-A1 (CA)
Title: Pipe cleaning vehicle
Inventor: SINZ HELMUT
IPC: E03F9/00
Filed: 1999-03-26
Abstract: The present invention relates to a mobile pipe cleaning vehicle and a process for cleaning pipes with a mobile pipe cleaning vehicle. The vehicle can be used to clean pipes, e.g., wastewater or storm drainage pipes. The vehicle includes a tank housing divided into three tanks: a sludge tank for holding water with a high degree of sludge and debris, a water supply tank for supplying water to a high pressure pump for high pressure spraying of a pipe to be cleaned, and a water-in-use tank disposed between the water supply tank and the sludge tank. Water used from the water-in-use tank is used for helping to create a seal in a liquid ring vacuum pump, enabling the sludge tank to be placed in a vacuum. Cooler water in the sludge tank and the water supply tank cool the water in the water-in-use tank to prolong the life and increase the efficiency in the liquid ring vacuum pump. A filtration system includes a first filtration device in the sludge tank, second and third filtration devices between the sludge tank and the water supply tank, and a fourth filtration device between the water supply tank and the high pressure pump. A water recycling pump pumps the water from the sludge tank through the first, second, and third filtration devices. If the water supply tank becomes substantially filled, the water recycling pump will pump water from the water supply tank through the second and third filtration devices to further clean the water. The fourth filter is disposed between the water supply tank and the high pressure pump to ensure that the water reaching the high pressure pump is virtually clean, thus significantly prolonging the life of the high pressure pump.

The frequency spectral characteristics of the second electrical signal are analyzed (26) to determine the spatial distribution of electrical impedance along the sensor, from which the levels of immiscible fluids within the vessel are determined.
