Patent CA-2653581-A1 (CA)
Inventor: BUTCHER KENNETH SCOTT ALEXANDER
IPC: C30B25/14
Filed: 2009-02-11
Abstract: A method of producing a thin film using plasma enhanced chemical vapour deposition, including the steps of supplying a cation species to a substrate region when there is at most a relatively low flux of a plasma based anion species in the substrate region, and, supplying the plasma based anion species to the substrate region when there is at most a relatively low flux of the cation species in the substrate region. This enables delivery of gaseous reactants to be separated in time in PECVD and/or RPECVD based film growth systems, which provides a significant reduction in the formation of dust particles for these plasma based film growth techniques.

Title: The electroshu
Inventor: SRIMOHANARAJAH KIRUSHA
IPC: A43B3/00
Filed: 2009-08-25
Abstract: Every day, the average person takes between 3,000 and 10,000 steps. Many people in third world countries average more than 20 000 since walking is the only transportation available. Every step taken consumes energy that was once released when bonds between molecules were broken. Its it possible to re-harness at least a portion of this energy through external devices. This energy can then be stored and used later to power electronic devices. This invention that this applications pertains to is a shoe modified in such a way that allows it to harnesses energy that would otherwise be wasted. Within the sole of shoe lies a number of solenoid magnet pairings (see figure 1,2,3) that induce current as the user walks. The movement generated as the foot compresses and relaxes the spongy material in the magnet pairing allow for changes in the magnetic field surrounding it. These changes cause induction. The current then flows through the copper wire and then is eventually stored within a rechargeable battery which is also contained within the shoe itself. This battery can be used to power or charge electronic devices when there is sufficient potential difference stored. Each shoe contains a varying number of solenoid magnet paring in such a way that energy generation is maximized and cost is minimized. Not only can this power be used to help save our environment, but also if theses generators are available in the mass market and are given out to people living below the poverty line (people in third world countries that are not on the power grid or cannot afford electricity) can have a chance to have a cheap form of power to light some parts of their dwellings for at least short periods of time.

A food system uses an integrated and compact motor and gearbox assemblies to drive the feed screws, and modular bearing assemblies on the shafts of the feed screws. The feed screws have heavy wall thickness flights. A sealed drum motor housed in the drive roller drives the hopper conveyor. The food system utilizes independent sensing means for indicating whenever the moldable food material accumulated at said one end of the hopper exceeds a given level. The cooling system with two fans and automatically closing dampers is improved and its placement and arrangement within the machine is optimized to save space and improve circulation. Linear displacement sensors are used in each hydraulic power cylinder. The machine utilizes improve seals between mechanical compartments and compartments in contact with food material. The machine provides a swing out electrical enclosure and chassis and uses modular I/O blocks to communicate between machine control and the solenoids.
