Title: Functionalized polymers for site-specific attachment
Inventor: OFFORD ROBIN E
IPC: A61K47/48
Filed: 1995-11-09
Abstract: Provided are organic polymers, e.g. poly(ethylene glycol), functionalized with an amino-oxy oxime-forming group and methods for their preparation and use in site-specific, chemoselective ligation to an aldehyde(or ketone)functionalized target macromolecule or surface under mild ligation conditions. Multi-polymer-containing amino-oxy-functionalized or aldehyde(or ketone)functionalized polymer constructs are also provided that allow site-specific, chemoselective ligation under mild conditions of the construct (and thus all of its polymers) to a single site on a target macromolecule via an oxime bond. Families of functionalized polymer constructs are also provided wherein each construct differs in topology but not in molecular weight (average) from the others in the same family. Methods for their use include the systematic modification of a target macromolecule to rapidly create a family of target molecules, preferably biologically important proteins, differing in topology but not molecular weight, from which family can be identified macromolecules having desired biological or physical properties, such as enhanced pharmacokinetic behavior.

Title: Automatic seismic pattern recognition method
Inventor: KESKES NAAMEN
IPC: G01V1/28
Filed: 1996-09-11
Abstract: An automatic seismic pattern recognition method is characterised in that it includes determining a given number of seismic patterns to be recognised;  providing a set of seismic trace portions for said region; defining a pattern recognition parameter common to all the trace portions, and determining the value of said parameter for each of the trace portions of the set; selecting trace portions among said set; selecting a one-dimensional neural network containing as many cells as there are patterns to be recognised, each cell being assigned a value of the recognition parameter; submitting the neural network to a learning process with the selected trace portions, so that at the end of said process, each cell matches a pattern to be recognised, and that said patterns are progressively ordered; presenting each trace portion of said set to be processed to the classified and ordered neural network; and attributing to each trace portion presented to the network the number of the cell closest to it. The invention is particularly useful for recognising seismic patterns between two horizons defined by plotting a seismic section.

IPC: E21F17/16
Filed: 1997-07-18
Abstract: The invention concerns a process for excavating by dissolution an underground cavity in a thin salt layer, in order to store a fluid therein.     According to the invention, the process comprises the following steps:          - producing an injection duct (16), an extraction duct (18), and a void (4) for a communication space (14) which places in communication the injection and extraction ducts;          - producing at least one blind tunnel void (2) communicating with the communication space so as to enable the solvent to circulate and the salt to dissolve in the blind tunnel;          - injecting via the injection duct a solvent in to the communication space; and - extracting via the extraction duct the brine formed by the dissolution of the salt on contact with the solvent.          The advantage of this solution is that the layer excavated has a mechanically stable shape and a larger volume and is produced more cheaply than with the prior art.

Abstract: A deployable telescopic seating structure employs a backstop arrangement to prevent users and operators from coming into contact with structure that may cause injury, such as interengaging metal elements that limit the extent of deployment. The backstop portions are arrangement in the aisle region of the telescopic seating structure and have an overall height that is responsive to the height of one seating level above another, or in another embodiment, to the difference between such height and an intermediate step. The backstop arrangement has an engagement portion with a flange element that extends transversely therefrom and which engages with a top surface of the seating level. Preferably, the engagement portion forms a forwardmost edge termination. A fastening portion is arranged intermediate of the engagement portion and the riser portion of the backstop member. Structural integrity and strength of the riser portion is enhanced by forming same as a multi-wall structure having supporting cross elements therebetween. The backstop arrangement can be formed as a continuous extrusion of a polymeric material, such as vinyl, which is fire retardant and which provides injury reducing resilience in the event of impact by a player. Lighting is incorporated into the multi-wall structure of some embodiments of the invention.

IPC: A62C2/24
Filed: 1998-05-08
Abstract: An electro-mechanical actuator maintains an external device to which the actuator is connected at an operating position when power is applied to the actuator, and allows the external device to return to a default position when the power is removed. Included in the actuator is a housing and an output coupling rotatably mounted thereon. The output coupling is configured to be connected to the external device and displaces the external device between the operating position and the default position. A driving device is mounted in the housing for providing a torque to the output coupling to displace the external device between the default position and the operating position when the driving device is energized. Also provided is a torque transmitting device for transmitting and changing the torque from the driving device to the output coupling. The torque transmitting device is cooperatively engaged to and is located between the driving device and the output coupling. Operatively connected to the torque transmitting device, a retracting device is configured for exerting a retracting force to return the external device to the default position via the transmitting device when the power to the actuator is removed. An important feature of the invention is a piezoelectric braking device for exerting a braking force on the driving device for maintaining the output coupling at the operating position against the retracting force exerted by the retracting device when the braking device is activated, and for releasing the braking force when the braking device is deactivated.
