Patent CA-2334650-A1 (CA)
Inventor: PRESCOTT RANDALL ISAAC
IPC: A01K85/00
Filed: 2001-02-05
Abstract: A topwater fishing lure is provided which comprises a hard body with a concave section at one end. The lure is designed so that the concave section floats above the surface of the water, and when pulled with a fishing line, the lure will topple over to immerse the concave section in the water. By doing so, the lure generates a noise which can act as an attractant to nearby fish. The lure may also contain two hooks with soft body devices attached to opposite sides of the hard body, which hooks hang straight down in the water to simulate the appearance of a frog, as bait.

Patent CA-2336695-A1 (CA)
Inventor: GNESIN BORIS ABRAMOVICH
IPC: C04B35/80
Filed: 1999-07-05
Abstract: The present invention pertains to the production of materials used in high-temperature oxidising media, wherein said materials can be used in the production of high-temperature electric heaters as well as in the production of parts, sensors and instruments operating at temperatures of 1900 °C and above. These materials, which essentially contain tungsten and molybdenum silicides MeSi2-Me5Si3 as well as silicon carbide, are characterised in that they exhibit high levels of heat-resistance, of resistance to thermal shocks, of high-temperature strength and of wear resistance. Doping with rhenium, tantalum, titanium, zirconium, niobium and hafnium silicides increases the mechanical properties of these materials. These materials, which have a desired porosity, can be used for increasing the specific electric resistance and for reducing thermal conductivity relative to high-density materials, while having a reduced density.

Title: Improved aromatic alkylation process
Inventor: HUANG YUN YANG
IPC: C07C2/66
Filed: 1999-11-04
Abstract: Alkylation product is contacted with a purification medium in a liquid phase pre-reaction step to remove impurities and form a purified stream. The purified stream is then further processed by liquid phase transalkylation to convert the polyalkylated aromatic compound to a monoalkylated aromatic compound. The process may use a molecular sieve catalyst such as MCM-22 as the purification medium in the pre-reaction step because of its high reactivity for alkylation, strong retention of catalyst poisons and low reactivity for oligomerization under the pre-reactor conditions. Olefins, diolefins, styrene, oxygenated organic compounds, sulfur containing compounds, nitrogen containing compounds and oligomeric compounds are removed.

Title: Process and apparatus for the manufacture of a digital color picture
Inventor: MUHLEMANN ARTHUR
IPC: G06T1/00
Filed: 2001-07-26
Abstract: A photographic original is photoelectrically scanned by way of a color-enabled scanning device for the manufacture of a digital color picture and a raw digital color picture is thereby formed from the scanning data obtained. The final digital color picture is formed by way of a color transformation of the raw color picture according to the principles of color management, whereby a device specific profile is used which describes the combination of the type specific colorimetric properties of the original and the transfer function of the scanning device used, with respect to an analog manufactured reference color picture. The different types of originals occurring in practice are assigned to categories according to colorimetric similarity criteria and a master original is selected in each category. Profiles are respectively created only for the master original. Depending on the quality required, different category assignments and selections of original type of master originals can be made. All original types of one category are processed using the same profile belonging to the master original of the category. A  true color digital image reproduction is achieved independent of the actual type of original used and the actual type of scanner used by inclusion of the color management into the manufacturing process of the digital color picture. The use of original type categories keeps the cost within practical limits.
