Title: Analog of haemophilus hin47 with reduced protease activity
Inventor: KLEIN MICHEL H
IPC: C12N9/52
Filed: 1995-07-21
Granted: 2001-05-29
Abstract: An isolated and purified analog of Haemophilus influenzae Hin47 protein has a decreased protease activity which is less than about 10% of that of natural Hin47 protein and preferably substantially the same immunogenic properties as natural Hin47 protein. An isolated an purified nucleic acid-molecule encoding the Hin47 analog may be provided in a recombinant plasmid which may be introduced into a cell which is grown to produce the Hin47 analog.      Immunogenic compositions comprising the Hin47 analog and the encoding nucleic acid may be formulated as vaccines for in vivo administration to a host, including a human, to confer protection against diseases caused by a bacterial pathogen, including Haemophilus species, such as Haemophilus influenzae, that produces Hin47 protein or a protein capable of inducing antibodies in the host specifically reactive with Hin47 protein. The Hin47 analog and the encoding nucleic acid also may be employed in diagnostic applications.

Abstract: A crank bait fish lure that has a predictable wobble or action. A fishing lure made from a blank of rigid material and formed to provide a predictable wobble or action in an arch of approximately 180°,  having a front end and a tail end. The front end has an eyelet to which a line is attached,  and the tail end has an eyelet to which a hook is attached.  A lure,  with no appendages, which is shaped to have a centre of gravity that causes a wobble from left to right and from right to left, while maintaining a horizontal attitude when drawn or dropped through water., thus allowing a lure to maintain an upright attitude. The degree of bend to the front end of a lure will effect the depth at which a lure will travel as it is drawn through water.  Change  in  the  elevation or plane at the tail end will alter the wobble or action slightly. A lure will maintain it's predictable motion when drawn through or dropped through water.

Abstract: A method for determining the geolocation of a user terminal within  a  telecommunications  system having a  constellation of satellites  which  relay  communications  signals  between  earth stations and user terminals over preassigned channels.  The method performs synchronization upon the telecommunications signals to calculate timing and frequency update information for the user terminals.   The timing and frequency update information is also used within the earth station to calculate the geoposition of the user terminal.  To do so, the earth station calculates a distance between  the  satellite  and  a  user  terminal  based  on  the corresponding propagation time therebetween which is obtained from the timing information.   Once  the satellite to user terminal distance is obtained,  a range solution line may be calculated therefrom.  In addition, the frequency update information is used to calculate a Doppler solution line upon which the user terminal is positioned.  Thereafter, the range and Doppler solution lines are combined to obtain points of intersection therebetween.  These points of intersection represent potential geolocations of the user terminal. The  earth  station  discriminates  between  these intersection points in one of several manners, such as the coverage beam spot or geographic cell assigned to the user terminal.  Upon obtaining a single intersection point, the longitude and latitude of this point or output is the geolocation of the user terminal.

Abstract: Testing of a transformer in an oil filled housing is done by providing an external arrester insulator/isolator penetrating and making an electrical connection through the housing while preventing leaking of oil from said housing. An arrester inside said housing is electrically coupled between an interior end of arrester isolator and a predetermined potential point within the housing. An exterior end of said arrester isolator is removably and electrically coupled to a ground potential point. The ground coupling is removed from the exterior end of the arrester isolator and the transformer is tested by measuring electrical characteristics on transformer connections emerging from the housing. The ground coupling is reconnected to the exterior end of the arrester isolator after testing is completed. If required, an insulating cap may be applied to the external isolator to provide additional withstand capability to external flashover during the tests.

Abstract: The invention is directed to a method of applying drug-release coatings whereby a polymer can be dissolved in a first solvent (solvent A) to form a polymer system and a drug can be dissolved or suspended in a second solvent (solvent B) to form a drug system.  The coating or layer of coating so formed comprises a substantially uniform combination of the drug and polymer.  Solvent B can be the same as or different than solvent A.  The coating can be applied on a stent body by separately spraying or dipping the polymer system and the drug system onto the devices.  The coating can be accomplished by either applying the polymer and drug systems sequentially or simultaneously.  In certain embodiments, a drug can be suspended in solvent B.  In some cases, three or more systems can be utilized.  For instance, a third system containing pure solvent A or B can smooth the coating surface, if the solvent of the third spraying system is compatible with the polymer matrix.
