Patent CA-2197863-A1 (CA)
Inventor: MCNEILLY LEONARD
IPC: C01B3/58
Filed: 1995-08-18
Abstract: An apparatus and method are provided for the two-stage selective oxidation of carbon monoxide to carbon dioxide in a fuel stream comprising hydrogen and carbon monoxide (21). The apparatus includes primary (11) and secondary (12) reaction chambers, which deliver a hydrogen-rich outlet gas stream having a carbon monoxide concentration of less than about 5 ppm. When an increase in the carbon monoxide concentration in the outlet stream of the primary reaction chamber (11) is detected, then the flow through the primary reaction chamber is reversed. The selective oxidizer (10) employs a temperature-based control strategy (30) as an oxygen-containing gas stream flow rate adjustment around the flow rate initially set in direct proportion to the fuel gas stream flow rate. The control strategy regulates the amount of oxygen-containing gas mixed with the gaseous fuel stream as a function of the difference between the temperature at a location at or near the end of the primary reaction chamber and the temperature at the outlet of the primary reaction chamber.
Patent CA-2199138-A1 (CA)
Inventor: BAUMGARTNER HEINRICH
IPC: B60B7/01
Filed: 1995-01-05
Abstract: Motor vehicle wheels are often damaged because the driver contacts the curb with the outer side of the wheel during parking. On contacting the curb, the tire, which generally protects the vehicle owing to its greater width, is often so greatly distorted that the outside of the wheel rim is crushed against the curb and is thereby damaged. A motor vehicle wheel (11) is produced with an annular device (13) which at least partly covers the visible side of the wheel rim (18). As the joint between the annular device (13) and the wheel is releasable, the annular device (13) can be easily changed after suffering damage and the wheel (11) once more looks as good as new.

Title: Vehicle anti-theft device separately simultaneously locking to the vehicle's steering wheel at each of two locations
Inventor: OPENIANO RENATO
IPC: B60R25/022
Filed: 1997-04-29
Abstract: Two parts telescope so as to selectively engage the steering wheel at a portion of its rim. A third part independently telescopes relative to the first two parts so as to span a remaining portion of the diameter of the steering wheel, and so as engage the rim of the wheel at a point opposite to the portion where are located the first and second parts. One single key lock suffices to lock all telescoping parts in position, selectively engaging or releasing the device from the steering wheel at two points. The impediment presented by the locked device to turning the steering wheel is not subject to being defeated merely by cutting through either the steering wheel, or the device itself, at any single location.

Inventor: GRAF MATTHIAS
IPC: B27N3/24
Filed: 1997-05-29
Abstract: The invention relates to a method of producing particleboards using a continuously operating press having endless steel bands which transfer the pressure of the press, are guided via drive rollers and deflecting rollers around a press ram and a press table and are supported via press cylinder-piston arrangements with an adjustable press nip against press heating plates of rolling support elements, the press heating plates at the top and bottom in the press nip distance being longitudinally adjustable with respect to one another by means of hydraulic press cylinders, and press table and press ram comprising a plurality of individual bars which are connected to one another in an elastic and vertically adjustable manner for a longitudinal bending deformation of the press heating plates.  In order to increase the longitudinal deformation gradient of the press heating plates, the invention consists in the fact that the upper and lower press heating plates are together deformed longitudinally to change the press nip, so that as a result a greater longitudinal deformation gradient can be set from the sum of [tan .alpha. + tan .beta.].

Abstract: Method and apparatus for detecting pressure waves caused by movement of a body organ, transmitted through a catheter (18) to an implanted medical device employing a pressure wave transducer (32) mounted in relation to the proximal end (40) of the catheter (18). The system may also include a reference transducer (34) having the same pressure wave response characteristics as the pressure wave transducer (32) but isolated from the proximal connector end (40) for providing a reference signal including common mode pressure wave noise that both transducers (32, 34) are simultaneously subjected to. The pressure wave signal and the reference signal are preferably amplified, bandpass filtered, stored, telemetered out or used to trigger a device operation. The pressure and reference wave transducers (32, 34) preferably are piezoelectric crystal transduces or accelerometers in direct or indirect mechanical contact with the proximal connector end (40) of the catheter and is encapsulated from the body within a device connector assembly (20). Cardiac pressure waves and respiration pressure waves are both transmitted proximally through the lead body (18) to the pressure wave transducer (32). Pressure wave signals may be derived in parallel to detect particular characteristic of the cardiac and/or respiratory cycle to provide timing signal(s) for controlling the device operations.

Title: Methods and devices for making intermediate oxidation products by controlling conversions and temperatures in an atomized liquid
Inventor: DASSEL MARK WILLIAM
IPC: C07C35/08
Filed: 1996-05-17
Abstract: Methods and devices for making intermediate oxidation products by atomizing a first liquid containing a reactant into a gas containing an oxidant in a manner to form an intermediate oxidation product different than carbon monoxide and/or carbon dioxide. The oxidation is controlled by monitoring and adjusting the temperature and conversion at one or more different stages of the reaction. The oxidation is also controlled by monitoring and adjusting the pre-coalescing transient conversion (conversion taking place in the time interval between the formation of droplets and their coalescence into a mass of liquid) of first reactant to oxidation product just before the droplets coalesce into a mass of a second liquid, or by monitoring the pre-coalescing temperature (temperature of the droplets just before they coalesce into a mass of liquid), or transient temperature difference (difference between the precoalescing temperature and the temperature of the droplets just before atomized), or transient temperature sub-difference (temperature difference between two positions within the reaction zone), or combination thereof. This invention provides waste minimization and considerable environmental improvement among other advantages.

IPC: G06F12/14
Filed: 1998-02-11
Abstract: The confidential information stored on an integrated circuit is rendered unintelligible by scrambling the values of the binary codes corresponding to the integrated circuit's instruction set. When appropriate, the codes are decoded by the integrated circuit's instruction decoder so that the intended function of the original (unscrambled) information is realized without revealing the information itself. This invention thereby provides a method of protecting confidential information stored on an integrated circuit by providing a unique (scrambled) instruction set for each application.
