Title: A dielectric loaded microstrip patch antenna
Inventor: ITTIPIBOON APISAK
IPC: H01Q9/04
Filed: 1999-12-03
Granted: 2007-02-13
Abstract: A dielectric loaded microstrip patch antenna is provided for delivering relatively wide operational bandwidth dual-band, with relatively good isolation and flexibility for circular polarization, while having a compact design and lightweight to suit mobile and wireless applications. The microstrip patch antenna has a conducting ground plane and a patch radiator. The patch radiator is spaced from the ground plane by a substantial distance having a first dielectric material therein. A slot feed in the ground plane provides the patch radiator with radio signal energy across the space having the first dielectric material therein. A piece of a second dielectric material is disposed adjacent the slot feed between the patch radiator and the ground plane. The second dielectric material has a dielectric constant that is higher than the dielectric constant of the first dielectric material. The piece of the second dielectric material acts to load the feed in order to improve coupling between the slot and the patch. The piece has a dimension along one of the x and y axes smaller than a dimension of the patch along a same axis. Since the piece is situated between the ground plane and the patch it determines operational characteristics of the microstrip patch antenna.
Patent CA-2292178-C (CA)

Granted: 2003-07-15
Abstract: A raw material gas containing hydrocarbon as a main component is supplied together with steam to a reformer through a moistening device to form a synthetic gas containing hydrogen, carbon monoxide and carbon dioxide as main components by the reaction between the hydrocarbon contained in the raw material gas and the steam. In forming the synthetic gas, carbon dioxide is supplied to at least one fluid passageway selected from the group consisting of the fluid passageway positioned upstream of the moistening device and the fluid passageway interposed between the moistening device and the reformer. As a result, the excess hydrogen contained in the gas formed in the reformer is effectively utilized without bringing about deactivation of the methanol synthesizing catalyst in the methanol synthesizing step. Also, carbon dioxide is effectively utilized to decrease the amount of carbon dioxide discharged to the outside of the system.      Further, it is possible to decrease the amount of steam supplied to the reformer.

Title: Removing a gaseous component from a fluid
Inventor: BETTING MARCO
IPC: B04C3/06
Filed: 1998-07-01
Granted: 2007-08-28
Abstract: A method of removing a selected gaseous component from a stream of fluid containing a plurality of gaseous components is provided.  The stream is induced to flow at supersonic velocity through a conduit so as to decrease the temperature of the fluid to below a selected temperature at which one of condensation and solidification of the selected component occurs thereby forming particles of the selected component, the conduit being provided with swirl imparting means to impart a swirling motion to the stream of fluid thereby inducing the particles to flow to a radially outer section of a collecting zone in the stream. A shock wave is created in the stream so as to decrease the axial velocity of the fluid to subsonic velocity, and the particles are extracted into an outlet stream from said radially outer section of the collecting zone, wherein the shock wave is created downstream the swirl imparting means and upstream the collecting zone.

Abstract: A rotary blowout preventer has a first and a second fluid circuit. Each of the fluid circuits are defined into and out of a stationary body and between the stationary body, a rotating body, and two seals. The first fluid circuit is physically independent from the second fluid circuit although they share a seal interface. A fluid is introduced into the first fluid circuit at a pressure responsive to the well bore pressure. A fluid is introduced into the second fluid circuit at a pressure responsive to and lower than the pressure of the fluid in the first circuit. Adjustable orifices are connected to the outlet of the first and second fluid circuits to control such pressures within the circuits. Such pressures affect the wear rates of the seals. The system can therefore control the wear rate of one seal relative to another seal. A thrust bearing is added to share the load placed upon the upper bearings. The thrust bearing is connected between the top end of a packer sleeve and the stationary body.

Abstract: The security reversible key with an assigned cylinder Z has a blocking groove BN with a coded blocking depth (B1, B2, B3), which runs parallel to the axis of the key (x) from the tip of the key to at least the first position (P1) of a row of tumbler pins (A2) on the key. In the assigned cylinder at least at the rearmost coding position (P1) a pair of tumbler pins corresponding to the blocking groove BN with a blocking tumbler pin BZ and an extended blocking counter pin BG are foreseen, whereby the blocking counter pin BG impinges on the cylinder housing (10), if the blocking groove is insufficiently deep and with this the complete insertion of a key with an insufficiently deep blocking groove is blocked by the pair of blocking tumbler pins. Simultaneously the blocking tumbler pin BZ with the counter pin BG at the position (P1) also serves as coding tumbler pin. In the case of the locking system with security reversible keys for locking installations at least two areas are defined, whereby in a first area G1 several additional security elements and a blocking code function and in the second area G2 a more simple basic coding are foreseen. With the first area G1, an unequivocal segmentation into independent market areas (M1, M2, M3) is defined and with this a world-wide unique locking system with enhanced security and applicability is created.

De plus, les règles d'association disjonctive sont généralisées dans le sens où l'algorithme exploite également les règles qui ont des disjonctions de conjonctions (C ~ (A.?.B).?.(D.?.E)). Puisque le nombre de combinaisons de disjonctions est explosif, nous avons recours au groupement pour trouver un sous-ensemble généralisé. Ledit groupement est préférablement formé à l'aide de méthodes de groupement pour trouver le sous-ensemble glouton.
