Patent CA-2330373-A1 (CA)
Inventor: TUCKER MARK
IPC: H04W88/14
Filed: 1999-05-19
Abstract: Systems for connecting telecommunications infrastructure lines t o telephone s, handsets, computers, telecopy machines and other end user interfaces or consumer electronics devices in a residence or business. Systems according t o the present invention include Network Control Units which form the center of  a star topology and which communicate via RF link with Wireless Access Units a nd handsets. Wireless Access Units feature an interface, such as, for example, a standard telephone jack, for accommodating a telephone, a fax machine, a compute modem or other device. In order to compensate for line loss, mismatc h and other incompatibilities between the public telecommunications network on  the one hand and systems according to the present invention on the other, ne w encoding techniques according to the present invention employ codecs which encode and decode using 10 bit code words, as compared to conventional mu-la w encoding and decoding which uses 8 bit code words. The resulting 16 bit performance yields a subjective 90dB signal to noise ratio over the radiofrequency link of systems of the present invention. Such encoding techniques and 10 bit code segments can easily be accommodated by present processing capacity which was not available in the era in which mu-law encoding was adapted.

Inventor: MEISTER JURG
IPC: F42D5/04
Filed: 1999-07-02
Abstract: To remove means of combat such as mines and unexploded ordnance increasing use is made of hollow charges. Inherent in these is the risk of triggering premature ignition since their liners contain metals. According to the invention a hollow charge (4) suitable for eliminating means of combat is configured largely free of metals and has a liner (3) made of an electrically non-conductive, amorphous material. The material of choice is glass, which when configured correspondingly in addition has a projectile-forming effect and thus raises penetration capability. Apart from lowering environmental pollution the use of metal-free devices also eliminates false alarm messages in metal detectors during mine clearance and therefore significantly improves the safety of mine clearance personnel. The support (16) carrying the hollow charge (4) is fitted with a ball joint (13, 14), resulting in high adaptability to the place of use and type of combat means (M) concerned.

Filed: 1998-08-21
Abstract: Solid state iron oxide reduction in a gas-solid reduction zone is combined with continuous melting of the hot solid reduced iron in a fuel-fired gas- solid-liquid melting zone within a rotary furnace. The process includes dire ct pneumatic transfer of the hot reduced iron by carrier gases through a transf er duct incorporating an injection lance nozzle projecting a jet of hot reduced  iron downwards into the metal bath within the melting zone. Oxygen is also introduced into the hot gas stream at selected locations in the melting zone  for post-combustion with carbon monoxide generated by a carbon boil and combustion with other combustible gases prior to exit from the rotary furnac e, thereby furnishing heat for melting. The hot gas stream is then utilized to provide a significant part of the heat requirement for reduction, prior to exhausting into the atmosphere. A feature is distributing the hot solid reduced iron laterally and longitudinally within the melting zone to enhance  heat transfer for melting, including a preferred embodiment comprising continually traversing the jet of carrier gases and hot reduced iron longitudinally forwards and backwards. The invention embraces a broad range of known solid-state reduction processes, classified either as: Group A) those employing gases within a gravity contact-supported or fluidized moving bed a t substantial pressures of 1-5 atmospheres; or Group B) solid carbonaceous reductants in a rotary kiln or rotary hearth conducted at near ambient atmospheric pressure. Combustibles in the exhaust gases and unnecessary fume  generation caused by direct injection of oxygen into the bath are avoided, a s problem endemic to known electric-arc and converter steelmaking technologies . A preferred embodiment applied to Group A reduction includes in situ reformi ng of a major portion of the hydrocarbons applied as reducing gases in the reduction zone, in combination with reforming a minor portion by partial oxidation with oxygen. The process includes various other preferred features  which significantly improve energy requirements, production rates, yields, costs and control of the liquid iron and steel product composition and quali ty in relation to the prior art.

Inventor: MOLOKOVA ELENA VALENTIN
IPC: C07K16/12
Filed: 1999-09-20
Abstract: La présente invention concerne un procédé permettant l'obtention d'un antigène de la paroi C-polysaccharidique de la cellule ne contenant pas plus qu'environ 10 % de protéine de la bactérie Streptococcus pneumoniae. L'antigène ainsi obtenu se conjugue à une molécule intercalaire, à la suite de quoi l'extrémité libre de cette dernière se conjugue à une colonne à affinité chromatographique. Cette colonne sert ensuite à purifier des anticorps bruts de S. pneumoniae, ce qui aboutit à la production d'anticorps spécifique de l'antigène. Une partie de tels anticorps se conjugue ensuite à un agent de marquage qui présente un changement de couleur visible dès la réaction des anticorps avec leur partenaire de liaison antigénique, puis s'imbriquent dans une première zone d'un dispositif d'essai immunochromatographique. Une autre partie de tels anticorps se lie à la zone de réaction du dispositif qui est pourvu d'une fenêtre d'observation. Lorsqu'on applique sur la première zone un échantillon de fluide du patient tel que de l'urine, du liquide céphalo-rachidien ou du sang, le conjugué des anticorps et de l'agent de marquage ainsi que l'échantillon se déplace le long de la bande d'écoulement de la matière buvard de la zone de réaction. Il en résulte que, si l'échantillon contient S. pneumoniae ou son antigène de paroi cellulaire, une structure sandwich se forme entre le conjugué marqué, l'antigène et les anticorps liés, ce qui donne lieu à l'observation d'un changement de couleur. L'essai immunochromatographique ainsi réalisé s'achève en environ 15 minutes. Cet essai constitue une base de diagnostic rapide et fiable de différentes pathologies à S. pneumoniae telles que pneumonies, bronchites, otites moyennes, méningites, et autres pathologies secondaires survenant généralement lorsque l'infection pulmonaire primaire provoquée par cette bactérie persiste au-delà d'une période de 3 à 5 jours.

Title: Apparatus for separating suspended fibrous material
Inventor: GERBER MILTON L
IPC: B01D46/46
Filed: 2001-06-07
Abstract: An apparatus for separating fibrous material such as wool, wood, paper, cellulose, rockwool, fiberglass, etc., which is conveyed by and suspended in air. The separator can be used with pneumatic vacuum systems and pneumatic pressure conveying systems for separating fibrous material used for insulation. The apparatus includes a housing having an inlet, an air outlet and a fibers outlet. An air lock is provided at the fibers outlet for allowing fibrous material to exit but generally restricting the air from exiting therethrough. A screen supported on a support fixture located at the air outlet allows air to pass but generally restricts fibrous material from exiting. The fibrous material is allowed to accumulate on the screen thereby forming a fibrous filter mat for filtering smaller fibrous particles.  Scalping blades travel over and at a distance from the screen thereby removing accumulated fibrous material and retaining the fibrous filter mat at a desired thickness for allowing air to pass but filtering smaller fibrous particles. The distance between the screen and scalping blades is selectively adjustable by selectively moving the screen for thereby selectively adjusting the thickness of the filter mat. A pressure transducer senses the differential pressure between the housing and the air outlet and increases the thickness of the filter mat in response to decreasing pressure differential and decreases the thickness of the filter mat in response to increasing differential pressure.
