Patent CA-2272238-A1 (CA)
Title: Vehicle anti-theft device
Inventor: CORDARA IRNANDO PEDRO
IPC: B60R25/08
Filed: 1999-05-14
Abstract: The invention, a vehicle anti-theft device, is in response to the increasing number of vehicle thefts. The device is for immobilizing a vehicle in preventing theft and/or unauthorized movement of the vehicle, whether the vehicle is running and left attended, or locked and secured. The anti-theft device is a hydraulic system connected to the brake lines, between the master brake cylinder and the wheel brake cylinders. By maintaining brake fluid to one-way flow from the master brake cylinder to the brake calipers, will prevent the wheels from rotation. The device engages a camshaft, placed within the devices' encasing, by the turn of a key lock rotary action. The key lock is connected to the camshaft, and the rotation of the key lock equally rotates the camshaft. The rotation of the camshaft operates the device between an engaged and disengaged position. In a disengaged position, the brakes are free to function as they would typically. In an engaged position, the device is not activated until the wheel brake pedal is applied. The application of the wheel brake pedal transfers the hydraulic pressure in the brake lines, this increase of pressure locks the wheel brake calipers. The engaged camshaft permits brake fluid to flow, increasing pressure, from the master cylinder to the wheel brake calipers, but the camshaft inhibits fluid flow in the opposite direction. Under this condition, pressure is maintained between the wheel brake cylinders and the activated device. The wheel brake calipers are locked and the vehicle cannot be moved by driving, or by lifting one-end of the vehicle by a tow truck without sustaining damage, until such time that the device is disengaged

Patent CA-2276914-A1 (CA)
Inventor: JAHN DARREN
IPC: A24F1/30
Filed: 1999-07-12
Abstract: The design of a traditional water pipe requires the user to suck on an opening in the chamber in order to draw smoke through water. The gravity powered water pipe uses the principal of displacement to accomplish the same task. The addition of a second chamber makes it possible for the user to lower the water level in the first chamber as gravity draws the water from one chamber to the other. The displaced water is used to pull air into the chamber and draw smoke through the water.

Title: Method for the transmission of voice information in atm cells
Inventor: HINTERBERGER CHRISTIAN
IPC: H04L12/70
Filed: 1998-01-13
Abstract: According to current ITU standardization, voice information is integrated in ATM cells by means of the AAL1 adaptation method, which takes into account the special characteristics of voice information.

Filed: 1998-07-28
Abstract: A system and method for conducting electronic payment transactions accepts and stores information describing an item sold by a merchant on a commerce server. The merchant also defines payment processing rules that define the payment methods accepted by the merchant. The merchant, in turn, is provided with a reference identifying the commerce server and the item. The merchant preferably publishes this reference at the merchant's web site on a web page offering the item for sale. A customer viewing the merchant's web site indicates a desire to purchase the item by selecting the reference. As a result, the customer is put in contact with the commerce server and is provided with information from the commerce server about the item and is given a list of payment options. The customer preferably selects a payment option and provides the commerce server with payment information, such as a credit card number. In response, the commerce server contacts a selected payment system and completes the electronic commerce transaction. The commerce server then notifies the customer and the merchant of the results of the electronic commerce transaction and delivers the item to the customer.

Title: Toolboxes and tool cases with pivotable component holder
Inventor: VASUDEVA KAILASH C
IPC: B25H3/06
Filed: 1998-08-05
Abstract: A tool container, such as a toolbox or gift case, has at least one pivotable component holder (10) pivotally mounted therein for pivoting movement between a storage position and an access position. The pivotable component holders are biased towards the access position when the lid (2) is open.      The tool container brings an element (24) directly or indirectly into contact with at least one of the pivotable component holders to rotate it to the storage position when the lid closes, with no direct connection between the lid and the pivotable component holders. Where there are multiple pivotable component holders, they may be ganged together, for example via a gang bar (18).      Instead of rotation of the pivotable component holders being triggered by lid closure, such rotation could be triggered by removal or storage of the tool (88) for which the components are intended. Pivotable holder components may be manipulated manually between storage and access positions when the lid is open and movement may be independent of the lid position.

Patent CA-2302755-A1 (CA)
Title: Novel method for making molecular sieves and novel molecular sieve compositions
Inventor: YEH CHUEN Y
IPC: C01B37/02
Filed: 1998-09-25
Abstract: This invention relates to the synthesis of large pore composite molecular sieves and the synthetic large pore composite molecular sieves so produced. The molecular sieves of the invention have the same general utilities of the comparable molecular sieves of the prior art but have been found to be superior catalysts and absorbents. This invention relates to a hydrothermal synthesis of large pore molecular sieves from nutrients, at least one of which contains an amorphous framework-structure, and which framework-structure is essentially retained in the synthetic molecular sieve. This invention stems from a discovery that the intrinsic porosity characteristics of a nutrient that possesses an amorphous cation oxide-framework can be substantially retained in the final molecular sieve containing product formed by a hydrothermal process by carefully controlling the conditions under which the hydrothermal process is conducted. For example, the invention contemplates retention of the particle size in a final molecular sieve-containing product that corresponds with that of an amorphous cation oxide-framework nutrient used in its manufacture. This invention drives the selection of process conditions to achieve one or more of macro and meso porosity ("large pore composite porosity") in the final molecular sieve product as a direct product of the hydrothermal reaction producing the molecular sieve. The invention allows the production of a molecular sieve that is in in situ incorporated in the framework morphology of a solid cation oxido-framework used in the molecular sieve's manufacture.
