Patent CA-2367948-A1 (CA)
Inventor: MALMGREN GORAN
IPC: H04L29/08
Filed: 2000-04-07
Abstract: In a wireline or wireless telecommunications system or data network, which employs a Selective Repeat Automatic Repeat Request (ARQ) to convey data packet reception status for a sequence of data packets grouped together into a number of blocks of data packets, partial bit mapping is employed to improve efficiency, particularly with respect to bandwidth. This may be accomplished, more specifically, by including in the ARQ message that is sent from the receiver to the sender, a number of partial bitmaps, along with a corresponding number of bitmap block numbers, where a first bitmap block number identifies a particular one of the blocks of data packets and the corresponding bitmap defines the reception status of the data packets in that block. Each of the remaining bitmap block numbers identify an additional block of data packets relative to the first block of data packets. Accordingly, the remaining bitmap block numbers require fewer bits to identify their corresponding data packet blocks.

Abstract: Disclosed is an in vivo method of incorporating exogenous genetic material into the genome of a vertebrate, which involves administering to a male vertebrate's testis a gene delivery mixture comprising a viral vector, such as a retroviral vector, to deliver a polynucleotide encoding a desired trait or product. Also disclosed is an in vitro method of incorporating exogenous genetic material into the genome of a vertebrate, in which germ cells are obtained from a donor male vertebrate and are genetically modified in vitro, before being transferred to a recipient male vertebrate. After the transfer, the male vertebrate bearing the genetically modified germ cells is bred with a female vertebrate such that a transgenic progeny is produced that carries the polynucleotide in its genome. Also disclosed are non-human transgenic vertebrates produced in accordance with the method, including transgenic progeny. A transgenic cell derived from the transgenic vertebrate is also disclosed, being a germ cell, such as a spermatozoan or ovum, a precursor cell of either of these, or a somatic cell. A method of producing a non-human transgenic vertebrate animal line comprising native germ cells carrying in their genome at least one xenogeneic polynucleotide is disclosed, as is vertebrate semen containing the transgenic male germ cells useful in practicing the method.

Title: Condensation and recovery of oil from pyrolysis gas
Inventor: UNTERWEGER ROBERT J
IPC: C10G1/10
Filed: 2000-04-28
Abstract: A system and process for the recovery of oil from the pyrolysis of material containing hydrocarbons such as shredded vehicle tires.  The system utilizes a pair of sequentially positioned packed towers to recover at least 95% of the oil contained in the pyrolysis gases. The first packed tower operates above the dew point of the water vapor in the pyrolysis gases to insure that no water is condensed and obtain a primary oil fraction having oil with a high flash point of about 60°C  or greater and a primary vapor fraction containing additional oils, fuel gases and water vapor. The primary vapor fraction is fed to the second packed tower which operates below the dew point of the water vapor to condense the water and oil having a low flash point of 34°C or below, and provide a secondary vapor fraction containing valuable fuel gases.

Abstract: A method of operating a bandsaw is disclosed. By stopping a bandsaw between saw cuts it is possible to reduce fatigue in wide bandsaw blades significantly. This, and a gullet (3.04) stress reduction strategy have resulted in a sixty three percent increase in bandsaw blade thickness (1.04, 2.02) for a given wheel diameter (2.05) while maintaining high strain. To achieve this it is necessary to redesign the bandsaw. To that end, descriptions of three bandsaw drive systems are described along with the required band wheel modifications.

Title: Sequence et proteine de liaison a l'adn utilisees en tant qu'isolants dotes d'une activite de blocage d'amplificateurs specifiques pour la regulation d'une expression genique
Inventor: WEST ADAM G
IPC: A61K48/00
Filed: 2000-04-19
Abstract: L'invention se rapporte à un élément isolant qui s'est avéré à la fois nécessaire et suffisant pour présenter une activité de blocage d'amplificateurs dans des cellules humaines. Cet élément isolant est une molécule d'ADN à 42 paires de base présentant une activité de blocage d'amplificateurs spécifiques qui permet la régulation d'une expression génique. Cet élément isolant s'est également avéré être le site principal de liaison à la protéine CTCF, une protéine de liaison à l'ADN qui est fortement conservée chez les vertébrés. En outre, un élément isolant comportant des sites de liaison à la protéine CTCF a été identifié dans la région du locus Igf2 qui est méthylé exclusivement sur l'allèle paternel. La méthylation de la séquence isolante supprime la capacité de liaison à l'isolant de la protéine CTCF et se traduit par une perte d'activité de blocage des amplificateurs.

Inventor: MENZEL DIETRICH
IPC: C21B13/00
Filed: 2000-09-26
Abstract: The invention relates to the reduction of ore fines, whereby said ore fines (1) are pre-heated in a multi-stage suspension-type heat exchanger (I), calcined and subsequently reduced in at least one lowest heat exchanger stage (2) by adding a reducing agent in a stream of hot gas supplied to said stage.  The invention aims to ensure an economic, constant reduction of ore fines in a relatively simple but extremely reliable manner, whilst at the same time permitting the suspension-type heat exchanger to be well regulated and controlled. To this end, the principal part of the reducing thermal treatment of the ore fines is carried out in a reactor loop (8) configured in the lowest heat exchanger stage of the suspension-type heat exchanger, with subsequent cyclone separation (2a) which is performed downstream of said loop. A hot reducing gas (7) is then introduced into the ascendant hot gas stream (5). The reducing gas is produced in a separate reactor vessel allocated to the reactor loop (8).

Title: Low density paperboard articles
Inventor: KOUKOULAS ALEXANDER A
IPC: B32B5/24
Filed: 2001-01-26
Abstract: The invention provides a low density paperboard material (12) and associated method for use in producing an insulated container, and is especially well-suited for making cups (10). The paperboard material (12) comprises a paperboard web including wood fibers and expanded microspheres (24), and has a relatively low density ranging from about 6 to about 101b/3MSF/mil, a relatively high caliper ranging from about 24 to about 35 mil, and an internal bond strength of at least about 80 × 10 -3 lft-lbf. For applications such as cups the material is also coated on one or both sides with a barrier coating, preferably low density polyethylene, to limit liquid penetration into the web. The low density paperboard material of the invention is convertible for manufacture of containers, particularly cups, and exhibits insulative properties comparible to higher cost materials conventionally used to make cups. Also, the surface of the low density board may have a sheffield smoothness of 300 SU or greater compared with the surface smoothness of 160 to 200 SU for conventional cupstock, the latter having been thought necessary for adequate print quality. However, it has been found that the low density board exhibits good printability on flexo printing machines despite its relatively rough surface, which is surprising and bonus effect realized along with the insulative and other properties of the board.
