Title: Gaseous acid catalysis
Inventor: ZEITSCH KARL J
IPC: C07D307/50
Filed: 2001-09-14
Abstract: A method of gaseous acid catalysis which finds particular applications in the manufacture of furfural includes the steps of introducing a solid reactant containing one or more hydroxyl groups into a reactor (1); introducing superheated steam from a superheater (2) until the temperature within the reactor (1) is higher than that of the dew points of both water and the catalyst and the reactant is dry. The catalyst is then introduced into the superheated steam by vaporiser (3). Product gas formed is liquified in condenser (4) and the condensate collected in a buffer tank (5). Separation plant 6 isolates the product gas and recovers the acid catalyst, preferably as its azeotrope with water, and recycles it into the vaporiser.

Abstract: The invention consists of the combination of a decorative jeweled/beaded "T"  shaped back connecting to a female's G-string/thong panty undergarment at two horizontal points in the hip region via jewelry clasps/connectors and connecting once vertically in the posterior via jewelry clasps/connectors. The removable jeweled "T" back intersects in the middle allowing for two horizontal and one vertical connection to aforementioned panty. The aforementioned panty is modified with jewelry receivers allowing for the attachment of "T" back on the right and left hip and upper buttocks region. This decorative jeweled "T" back will be exposed when worn under today's low rise/hip hugger trouser fashions due to the cut of low rise/hip hugger fashions. This invention serves two purposes, it is a decorative accessory, and it alleviates self-consciousness often felt by females when exposed to the side effect of low rise/ hip hugger fashions.

Abstract: L'invention concerne un nombre suffisant de dispositifs de transfert (des rouleaux, par exemple) (162-167), dont les périodes de contact avec un substrat sont égales ou sensiblement égales l'une à l'autre, utilisés pour former des revêtements uniformes, sans vide et continus, malgré l'apparition prévue ou non de variations soudaines, de dépressions et de vides dans le calibre de revêtement. Les surfaces mouillées des dispositifs viennent en contact et reviennent en contact avec le revêtement, au niveau d'emplacements sur le substrat qui sont différents les uns des autres. On peut ainsi obtenir des revêtements extrêmement uniformes et extrêmement fins, à de très fortes cadences. Ces dispositifs de transfert facilitent également le séchage et réduisent la sensibilité des étuves de séchage aux variations soudaines du calibre de revêtement. L'équipement contenant ces dispositifs de transfert est simple à construire, à installer et à faire fonctionner. Il peut également être facilement ajusté pour modifier l'épaisseur de revêtement et compenser le calibre de revêtement.

Title: Error correction scheme for memory
Inventor: FOSS RICHARD C
IPC: H03M13/29
Filed: 2003-10-28
Abstract: An embedded DRAM ECC architecture for purging data errors is disclosed. The embedded DRAM ECC architecture is based upon a two-dimensional linear parity scheme, and includes a plurality of memory blocks and a parity block. Each memory block includes additional columns for storing row parity bits, and the parity block stores column parity bits. A row parity circuit coupled in parallel to an existing local databus of each memory checks the parity of the local databus bits against a row parity bit during a refresh or read operation in order to identify parity failure for the word.  Identification of the incorrect bit of the word is achieved by iteratively transferring the data of the local databus of each memory block onto an existing global databus, and checking the parity across the global databus with a column parity circuit. When global databus parity failure is detected, all bits of the global databus are inverted to purge the incorrect bit from the memory block via the local databus. A method for initializing the memory upon power up in order to prepare the memory for writing data, and methods and circuits for generating the corresponding row and column parity bits during a write operation are also disclosed.

Patent CA-2447767-A1 (CA)
Inventor: WEISENBERG DOUGLAS S
IPC: H04M3/46
Filed: 2003-10-31
Abstract: The present invention provides distributed communication services based on a presence technology platform. Presence messaging and communication techniques allow a variety of communication agents to cooperate with one another to provide distributed services. Essentially, the messaging between the agents is used to facilitate media sessions and update participating devices of state changes bearing on providing the services. In one embodiment, each of the participating devices is associated with a logic entity, referred to as a presentity, which subscribes to notification services for the other participating devices. When a state change occurs on any one of the participating devices, the corresponding presentity notifies the other devices of the state change. As such, each participating device knows the status of the other participating devices via the presentities and can systematically determine when and how to provide services based on its current state and the current state of the other participating devices.

Title: Oil filter cartridge
Inventor: SMITH ELLIS JUNIOR
IPC: B01D35/147
Filed: 2004-02-12
Abstract: The present invention relates to small vehicles such as lawn and garden tractors and more specifically to an oil filter cartridge or assembly usable with the transmissions of such vehicles. The cartridge is comprised of a filtering element, a strainer element and a by-pass valve. The by-pass valve is housed within the strainer element and is adapted to direct oil flow through the strainer element, but not the filter element when the oil viscosity is high and only through the filter element when the oil viscosity is low. In this way, the parasitic horsepower loss caused by routing oil through the strainer element at all times is eliminated. The cartridge is also housed within the transmission case to reduce mounting bracketry outside the transmission case and minimize the likelihood of insufficient oil supply available for the filter, pump and hydraulic system functions.
