Patent CA-2245581-A1 (CA)
Inventor: GROTEN WILLIBRORD A
IPC: C07C41/05
Filed: 1996-12-31
Abstract: A process for removing dienes from etherification uses a hydrogenation zone (24) in the reactor distillation column (20) above the etherification zone (22). MTBE is produced and the unreacted C4 stream is also subjected to selected hydrogenation of the butadiene contained in the C4 feed stream. The C4 stream is introduced via line (101) and methanol is introduced via line (102) which is combined in flow line (104) and subsequently enters the distillation column (20) via line (103) wherein the C4 stream is contacted with methanol in the etherification zone (22) where the MTBE is distilled downward. The unreacted C4's then are subjected to selective hydrogenation in the hydrogenation zone (24) wherein butadiene in the overhead raffinate (108) is reduced by over 90 %. The hydrotreated C4's are thus suitable for cold acid alkylation or other use wherein butadiene is harmful.

Title: Establishing communication in a packet data network
Inventor: GITTINS CHRISTOPHER JOHN
IPC: H04L29/06
Filed: 1997-02-07
Abstract: Communications are established between a source user (305) and a destination user (307). Data is transmitted between these users in packets (204) having a destination address (205) and communication data (206). A destination name is identified in a first packet and this packet is transmitted to a service control platform (301) identifying, in its communication data, a destination name. A packet is then returned from the control platform (301) to the originating source (305) identifying a real contactable address for the identified destination (307). Subsequent packets of data are generated at the source (305) for transmission to the destination (307) wherein the transmitted packets have the actual destination address, as returned from the service platform, appended thereto.

Title: Communication method using common cryptographic key
Inventor: BABA YOSHIMI
IPC: H04L9/08
Filed: 1997-02-19
Abstract: A communication method using a common cryptographic key by which security against various kinds of attacks can be improved while the preparation of a common cryptographic key prepared at the time of performing communication or a cryptographic communication system on a network is simplified. At a center, a personal key peculiar to each entity is prepared by applying Fourier transformation with weight function and center matrix to the identifier of each entity (procedures 2-1 and 2-2) and performing randomized transformation based on one-time random number data prepared by artificial processing of the entities (procedures 2-3 to 2-5) and, at the same time, an identifier converting algorithm is prepared based on the random number data and Fourier transformation with weight function (procedure 2-6) and distributes the algorithm and personal keys to the entities. Each entity prepares a common key used for performing cryptographic communication with a partner by applying the identifier converting algorithm and personal key to the identifier of the partner.

Title: Information communication system
Inventor: OKANO SHOKO
IPC: H04Q11/04
Filed: 1998-03-13
Abstract: An information signal is supplied to a host computer through a B-channel of ISDN from a terminal unit connected with the host computer. On a television monitor of the host computer, a shot image of a terminal unit and an indication of the terminal to which the shot image belongs are displayed. When anomaly is detected at another terminal unit, a connection request signal and an anomaly discrimination signal are supplied to the through a D-channel of ISDN. On the television monitor, the terminal at which anomaly is detected and the descriptions of the anomaly are displayed. A terminal unit connected with the host computer is switched through the B-channel to the terminal at which the anomaly is detected, automatically or in accordance with operation by a user. An information signal is transmitted to the host computer from the terminal unit at which the anomaly is detected. A shot image of the terminal unit at which the anomaly is detected, the identification of the terminal unit at which the anomaly is detected, and the descriptions of the anomaly are displayed. Thus, monitoring may be carried out by a single host computer using a plurality of terminal units.

Filed: 1997-07-02
Abstract: An improved method of adding vitamins to a food product, particularly a reduced fat fried snack product, and a vitamin suspension containing a flowable edible, preferably a nondigestible fat, and encapsulated or powdered vitamins. The method consists of suspending the encapsulated or powdered vitamins in the flowable edible fat, and applying the suspension in a controlled amount to the surface of a food product. The preferred food product is a fabricated reduced fat or fat-free potato chip which is a fried snack made by frying a dough in a nondigestible fat to a moisture content of less than 5 %. The vitamin suspension is applied to the surface of the fried snack soon after emerging from the fryer. The food product has a light, crispy, improved crunchy texture, improved flavor and a fat content of from about 20 % to about 38 % nondigestible fat, and is fortified with vitamins.

Title: Light wave diffraction device
Inventor: SYCHUGOV VLADIMIR A
IPC: G02B5/18
Filed: 1999-01-22
Abstract: Light wave diffraction device formed of a dielectric layer (4), a reflecting structure (12) arranged on one lower face (10) of said layer, and a diffraction grating (8) arranged on one face (6) of said layer. The height (H) of the layer is selected so as to substantially satisfy the resonance condition for a leaky mode in said layer for at least one given incident wave having a wavelength .lambda. and a determined angle of incidence. Next, the diffraction grating has a spatial period selected so that the incident wave is diffracted essentially along the first negative diffraction order and at an angle of diffraction different to the angle of incidence (outside the Littrow condition). In particular, the invention provides that either the angle of incidence, or the angle of diffraction is high, i.e. relatively close to 90° from the direction perpendicular to the diffraction grating. This diffraction device allows a very high diffraction efficiency, of up to 100%, to be obtained, even when the incident wave is grazing.

Abstract: A method and apparatus (10) for separating a mixture of materials having different sizes and densities is described. The apparatus includes a trough (12), a dispersing and conveying screw (40) and fluid distribution manifolds (26 and 28). The screw has a dispersing portion (50) with paddles (52) which disperse the mixture and a conveying portion (46) with flights (48) which move the first and second materials (152 and 154) up the trough. The fluid distribution manifolds supply both water and air to the trough through fluid orifices (30 and 32). A spray bar (56) is located adjacent the conveying portion of the screw. The mixture is fed into the trough over the fluid orifices and the dispersing portion of the screw. The mixture is dispersed and forms an aqueous suspension (158) with the water. The first and second materials settle out of the aqueous suspension and are conveyed up the trough. The third material (156) remains suspended in the aqueous suspension and flows over the overflow weir (20) and out the lower discharge spout (24). The second material is washed out of the first material by the spray bar and flows back down the trough to be discharged with the third material.

Patent CA-2268080-A1 (CA)
Inventor: LEHAN DAVID RALPH
IPC: B65F1/16
Filed: 1999-03-22
Abstract: When household items such as papers, tins, bottles, etc. are to be re-cycled they are normaly placed curb side in a container commonly referred to as a "Blue Box". Often times during inclement weather conditions the contents of the blue box become saturated by rainfall and blown out of the box by the wind. The scattered contents then becomes litter and raises an environmental issue. This invention is a water resistant fabric cover for the blue box that will contain the contents even when the box has been overloaded with the contents protruding above the top of the box. The cover is held in place with an elastic bungee cord sewn into the hem of the cover. The bungee also attaches the cover to the blue box by extending out from the hem by approximately two feet and being inserted through one of the drain holes in the bottom of the box and tied off.
