Title: System and method for schemaless data mapping with nested tables.
Inventor: YIU-MING LEUNG
IPC: G06F40/143
Filed: 2005-03-18
Abstract: A system and method for mapping payload data to a spreadsheet list. The present invention comprises a system for mapping payload data to a spreadsheet list while supporting the implementation of nested tables, without the use of a schema. After receiving a spreadsheet list, the present invention generates the parent path of each field path defined in the spreadsheet list. The longest parent path may be used to generate a set of nodes from the payload data. If more than one unique parent path qualifies as the longest parent path, then such parent patents may be designated as branch bottom paths. All other parent paths may then be associated with an appropriate branch bottom path. During the binding process, each branch bottom path may be evaluated to generate result nodes, which may be used to obtain the values of the fields of the spreadsheet list.

Patent MX-PA06000183-A (MX)
Title: Oxygenate conversion reactor catalyst coolers.
Inventor: MILLER LAWRENCE W
IPC: C07C1/20
Filed: 2006-01-05
Abstract: A process of converting oxygenates to light olefins is disclosed including an oxygenate feedstream with contacting catalyst inside a reactor and converting the oxygenate feedstream to said light olefins. The catalyst becomes spent as deposits from the reaction clog up pores on the catalyst surface. A portion of the spent catalyst is regenerated in a regenerator and a portion is circulated back to contact more of the oxygenate feedstream. A catalyst cooler attached to the reactor can cool the spent catalyst circulated through the cooler before the spent catalyst contacts more of the oxygenate feedstream. In an embodiment, all of the spent catalyst that enters the catalyst cooler is withdrawn from the bottom of the catalyst cooler.

Title: Medical bandage product and substrate with para-aramid fiber reinforcement.
Inventor: EVANS JOHN C
IPC: A61F13/04
Filed: 2004-02-04
Abstract: A medical bandaging product for being dispensed in predetermined lengths suitable for a given medical use, and includes an elongate sleeve formed of moisture-impervious material and sealable to prevent entry of moisture and an elongate medical material positioned in the sleeve and sealed therein against entry of moisture until use. The medical material includes a substrate formed of a single thickness layer formed of first yarns. The second yarns are integrated into the single thickness layer of the first yarns. The second yarns are high-strength, high modulus fibers for increasing the strength and dimensionally stabilizing the substrate. A reactive system is impregnated into or coated onto the substrate, the system remaining stable when maintained in substantially moisture-free conditions and hardening upon exposure to sufficient moisture to form a rigid, self supporting structure. A soft, flexible protective wrapping encloses the substrate along its length to provide a cushioning barrier between the substrate and the skin of a patient when the material is in use. A clip or other closure devices is provided for resealing the sleeve against entry of moisture after a predetermined length of the bandaging product has been dispensed for use to prevent hardening of the substrate remaining in the sleeve.

Patent MX-PA06013911-A (MX)
Title: Connector .
Inventor: FUNAMURA SHIGEAKI
IPC: A61M39/00
Filed: 2006-11-29
Abstract: PROBLEM TO BE SOLVED: To provide a connector, comprising a valve member capable of securely disconnecting continuity to the external when unused without a risk of leak or propagation of bacteria. ; SOLUTION: The valve member 40, installed on an opening part 13b of a third branch tube 13 is provided with a main body part 41, a first support arm 42a, and a second support arm 24b. An outer surface 41a of the main body part 41 is communicated with a third branch passage 13 when the main body part 41 is pushed into the third branch passage 13a by means of a lure part. At this time, an inner slit 41d is opened, and a grooved dent S is formed in the outer surface 41a. Fluid from the lure part is fed through the dent S to the third branch passage 13a. As the lure part is released from the outer surface 41a of the main body part 41 to eliminate pushing force, the main body part 41 restores to an original position, thus securely disconnecting the third branch passage 13a from the external. ; COPYRIGHT: (C)2007,JPO&INPIT.
Patent MX-YU04000007-A (MX)
Title: Water discharge device which is positioned at the centre of a toilet cistern.
Inventor: BAEZA CARLOS ABEL DORANTES
IPC: E03D5/012
Filed: 2004-06-29
Abstract: The invention relates to a water discharge device which is positioned at the centre of a toilet cistern. Toilet cistern construction involves the use of mechanical seals which can comprise different shapes and materials, which are equipped with an operating and control actuator and which enable the water contained in the toilet tank to be discharged. More specifically, mechanical seals for toilet cisterns, which are equipped with an operating actuator, serve as discharge valves which enable or prevent the passage of liquid. Generally, said mechanical seals comprise a fixed base and a mobile part which, when joined together, block the passage of liquids, all of said elements being produced and used for said specific purpose. The inventive device interrupts the flow of water being discharged from the tank to the bowl, using a cylindrical barrier which is taller than the required maximum water level in the cistern. According to the invention, when the aforementioned cylinder contracts be low the water level, under the effect of an actuator, part of the water can be discharged from the cistern to the bowl and the interior of the device fills with water. A siphon effect (absorption by gravity) is generated owing to the fact that the outlet of the discharge cylinder is lower than the base of the toilet tank or cistern, and the weight of the water in the device ensures that the retractable cylinder remains contracted. In this way, the device can absorb water from the base of the cistern. Upon termination of the water discharge operation, the device fills with air and is freed from the weight of the water contained therein. As a result, the retractable cylinder can return to the initial position thereof, thereby enabling the toilet tank or cistern to be filled with water up to the required level. In addition, the floatation capacity of two small cylinders, which are disposed at the upper sides of the cylinder (1), enables same to be positioned slightly above the water leve l required in the toilet cistern. The water inlet of the conical part of the cylinder (2) maintains the device such that it is ready to repeat the above-mentioned operation. As such, the device does not require a mechanical seal for operation.

Title: Raster distortion correction arrangement
Inventor: JOHN BARRETT GEORGE
IPC: H01J29/56
Filed: 1994-12-06
Abstract: A VERTICAL RATE SIGNAL GENERATOR (101) IS COUPLED TO AN TNTEGRATOR (102) FOR PRODUCING A VERTICAL RATE PARABOLA SIGNAL (VPAR). THE PARABOLA SIGNAL IS APPLIED TO A BAND-PASS FILTER (104) FOR PRODUCING A VERTICAL RATE SINUSOIDAL SIGNAL (VSIN) THAT IS APPLIED TO A CONVERGENCE WINDING (78). WHEN A LOSS OF THE HORIZONTAL SYNCHRONIING SIGNAL OCCURS, THE FREQUENCY OF THE SAWTOOTH SIGNAL (VSAW) DECREASES. AS A RESULT, THE DC, AVERAGE LEVEL OF THE SINUSOIDAL SIGNAL VARIES,DURING A TRANSITION INTERVAL (TR), FOLLOWING RESTORATION OF THE HORIZONTAL SYNCHRONIING SIGNAL. THE BAND-PASS FILTER FILTERS OUT LOW FREQUENCY COMPONENTS. THE DURATION OF THE TRANSIENT INTERVAL IS THEREBY REDUCED IN A MANNER TO REDUCE PICTURE BOUNCE. THE PEAK AMPLITUDE OF THE SAWTOOTH SIGNALS ALSO CLIPPED (BY02) FOR REDUCING THE VARIATION OF THE AVERAGE LEVEL OF THE SINUSOIDAL SIGNAL.

WHEN A QUALITY OF THE FEEDBACK LINK BECOMES UNACCEPTABLE, THE BASE STATION (16A, 16) AND THE MOBILE STATION (12) ENTER INTO AN ALTERNATIVE MODE OF OPERATION, ADJUSTING FROM A FAST POWER CONTROL FEEDBACK MODE (WITH A HIGH BANDWIDTH FEEDBACK CHANNEL AND LOW POWER CONTROL DELAY), TO A SLOW POWER CONTROL FEEDBACK MODE ( WITH A LOW BANWIDTH FEEBACK CHANNEL OR A LONG POWER CONTROL DELAY). THE MOBILE STATION (12) ADJUSTS A RATE OR CONTENT OF POWER CONTROL MESSAGES IT FEEDS BACK TO THE BASE STATION (16A, 16B) UNDER A VARIETY OF METHODS. UNDER THIS ALTERNATIVE MODE, THE MOBILE STATION (12) INCREASES A POWER OF ITS FEEDBACK SIGNALS. ADDITIONALLY, IF THE MOBILE STATION (12) IS IN A SOFT HANDOFF CONDITION, IT SIMILARLY INCREASES A POWER OF ITS FEEDBACK SIGNALS. IF THE BASE STATION (16A, 16B) DETERMINES THAT THE RECEIVED POWER CONTROL MESSAGES ARE UNACCEPTABLE, THE BASE STATION EMPLOYS POWER CONTROL MESSAGES IT RECEIVES FROM A BASE STATION CONTROLLER (14).FIG 5A&5B
