Title: Corner cutter
Inventor: MOMOSAKI MITSUKAZU
IPC: B26B17/00
Filed: 2001-01-23
Granted: 2006-07-18
Abstract: A cutting operation that is a finishing grinding pretreatment for a plate glass corner treatment is carried out using a corner cutter having, for example, upper and lower blades for cutting plate glass by opening and closing the respective upper and lower blades. The upper and lower blade edge lines of the upper and lower blades mutually oppose each other in the upper and lower blade edge section of a cutter body that is formed in an almost scissor shape. The same upper and lower blade edge lines almost coincide to the planned cut line of the corner section of the plate glass.

Title: Draught beverage containing ice
Inventor: SCULLION SIMON DANIEL
IPC: B67D1/04
Filed: 1999-05-14
Granted: 2012-04-17
Abstract: A draught beverage (170) which may be alcoholic or non-alcoholic, for example a lager or cider in an open-topped drinking vessel or glass (172). The beverage comprises a water content and dissolved gas content. The draught beverage is dispensed from a font at a cooled temperature below the freezing point of water at ambient atmospheric pressure. The dispense temperature may be in the range of -1 ~C to -12 ~C. The beverage in the glass may or may not be subjected to external excitement energy, for example ultrasound, to encourage formation of nucleation sites in the beverage. Either way dissolved gas bubbles out of the beverage causing occurrence of nucleation sites at which ice (188A, 188B) from the water content forms. At least in part the ice has a slushy character. A head (174) also forms on the dispensed draught beverage and below the head the ice (188A, 188B) locates and develops downwards into the beverage.

Title: Oxy-fuel combustion system and uses therefor
Inventor: GROSS DIETRICH M
IPC: C22B1/00
Filed: 2002-03-22
Granted: 2004-06-01
Abstract: An oxygen fueled combustion system includes a furnace having at least one burner, an oxygen supply for supplying oxygen having a predetermined purity, and a carbon based fuel supply for supplying a carbon based fuel. The oxygen and the carbon based fuel are fed into the furnace in a stoichiometric proportion to one another to limit an excess of either the oxygen or the carbon based fuel to less than 5 percent over the stoichiometric proportion. The combustion of the carbon based fuel provides a flame temperature in excess of 4500°F. The exhaust gas stream from the furnace has substantially zero nitrogen-containing combustion produced gaseous compounds from the oxidizing agent and reduced green-house gases.  Substantially less carbon based fuel is required than conventional combustion systems without a loss of energy output.

Granted: 2014-08-19
Abstract: A method and apparatus is disclosed for increasing the world-wide-web traffic over the Internet with the aid of distributed specialized nodes of two types while retaining standard communication protocols, clients and servers.  Accordingly, web client (10)'s request is directed to a specialized first node of the first type (12-1), chosen suitably close to web client (10), using a standard protocol (11). First node (12-1) communicates, using a specialized protocol (13) for improved performance and specifically to reduce traffic volume and latency, web client (10)'s request to a second node (14-2) of the second type. Second node (14-2), chosen suitably close to the request's ultimate destination (16), forwards the request to destination (16) employing standard protocol (11). Responses from the destination (16) to the client (10) typically take the corresponding reverse route. Additionally, specialized nodes can employ other techniques including web caches to avoid or improve some communication steps.

Granted: 2013-02-05
Abstract: Dans les systèmes qui transmettent à la fois des signaux modulés GSM et des signaux modulés EDGE, les estimations de temps d'arrivée peuvent être améliorées sans nécessiter la détection du type de modulation utilisé sur le signal reçu. Selon l'invention, un signal reçu est démodulé initialement par un récepteur en fonction d'un premier schéma de démodulation. Ce signal démodulé est divisé en deux copies. La démodulation initiale étant prise en compte, une des copies est démodulée en fonction d'un autre schéma de démodulation, ce qui permet l'obtention d'un premier signal démodulé en fonction du premier schéma de démodulation et d'un second signal démodulé en fonction d'un second schéma de démodulation. Une séquence d'apprentissage est utilisée pour corréler les deux signaux qui sont ensuite additionnés selon un procédé d'intégration incohérente. Le résultat de l'intégration incohérente est utilisé pour estimer le temps d'arrivée du signal reçu.
