Title: Immobilized activity stabilized lhrh antagonist complexes, method for the production thereof
Inventor: MURGAS SANDRA
IPC: A61K47/48
Filed: 1998-03-11
Granted: 2007-08-21
Abstract: The invention relates to a retard system for LHRH antagonists, specially cetrorelix, based on complexation with suitable biophile carriers enabling targeted release of the active substance over a period of several weeks. Acidic polyamino acids, polyasparaginic acids and polyglutaminic acids are selected for complexation with cetrorelix. The cetrorelix polyamino acid complexes are produced from aqueous solutions by combining the solutions and precipitating the complexes which are subsequently centrifuged off and vacuum dried by P2O5, lyophilization proving to be a suitable method. The acidic polyamino, polyglutaminic and polyasparaginic acids display good retarding properties in a static liberation system depending on the hydrophobicity and the molar mass of the polyamino acids. Animal testing demonstrates the principal efficacy of the cetrorelix polyamino acid complexes as a depot system. By complexation of cetrorelix with polyamino acids, testosterone suppression can be achieved in male rats over a period of 600 hours. Active substance release can thus be controlled according to polymer type and molar mass.

Abstract: A spring trip standard for a tillage implement includes a coil spring compressed between an upper spring-abutting surface on the mounting bracket and a lower spring abutment surface on a casting which is connected by a transverse pivot to the mounting bracket. The casting includes an integral stop extending forwardly from the pivot and contacting the bottom of the bracket when the shank is in the ground working position so that a tension link between the bracket and casting is eliminated. The casting includes a spring abutment surface having a first portion which extends generally perpendicular to the spring axis to support the lowermost end of the spring when the shank is stopped in the normal working position. The opposite side of the spring abutment surface is angled relative to the first portion, and the lowermost coil of the compressed spring, when the standard is in the tripped position, abuts the opposite side to maintain the spring in a non-buckling state. The lowermost coil is maintained generally perpendicular to the centerline of the coil spring in the field-working and tripped positions so that spring buckling and spring fatigue caused by buckling are reduced or eliminated.

Title: Electrochemical sensors made from conductive polymer composite materials and methods of making same
Inventor: FOULGER STEPHEN H
IPC: G01N27/12
Filed: 2000-03-15
Granted: 2009-05-19
Abstract: An electrochemical sensor which is tailored for sensitivity to specific chemical analytes by selecting proper constituents. The electrochemical sensor is comprised of an immiscible polymer blend of at least two polymers in which a conductive filler is dispersed in one of the polymers of the blend through a multiple percolation approach to compounding. When in the presence of a chemical analyte which is in either a liquid or vapor phase, one phase of the dual immiscible polymer blend swells, effecting a decrease in the conductivity, or increase in resistivity, of the polymer blend. The electrochemical sensor is reversible in that when the chemical analyte evaporates or is removed, the polymer blend returns to its original conductivity. With the multiple percolation approach it is possible to make a single composite material identifiably sensitive to various chemical analytes by incorporating several major phase materials into the immiscible polymer blend, each having an affinity for swelling for a different analyte. Further, the multiple percolation approach allows sensors to be made at extremely low cost.

Abstract: A method of controlling, in response to a shift command, a commanded shift of a powershift transmission of an engine-driven vehicle includes monitoring speeds transmission component selected according to the commanded shift and monitoring a speed ratio therefrom. If the input section will speed up during the commanded shift, the speed clutches are swapped, and then the output clutches are swapped when the monitored speed ratio matches a stored speed ratio. Also, the input speed of an input shaft of the transmission is monitored, and the pressure of the off-going output clutch is controlled to limit the deceleration of the input shaft speed to desired limits. If the input section will slow down during the commanded shift, the output clutches are swapped, and then the speed clutches are swapped when a monitored speed ratio matches a stored speed ratio. If a particular shift requires swapping of only speed clutches, then a speed ratio is monitored for the pair of the speed clutches to be swapped. If the input section will speed up or slow down during the commanded shift, the pair of speed clutches are swapped, and the monitored speed ratio is compared to a predetermined stored speed ratio value to determine when swapping of the speed clutches is completed, and after the speed clutches are swapped, one of the output clutches is fully pressurized to complete the shift.

Filed: 2000-09-25
Granted: 2004-11-02
Abstract: Methods and apparatus for communication with a downhole tool including uphole (or remote) and downhole equipment. The uphole or remote equipment includes a signal source (or array) coupled to a programmable triggering system and a precision clock. Optionally, the uphole equipment may include receivers for capturing reference signals near the source and may include telemetry equipment for receiving MWD signals from the downhole equipment. The downhole equipment includes one or more receivers, signal processing equipment, memory, and a precision clock. Optionally, the downhole equipment also includes MWD telemetry equipment for transmitting data to the surface. The methods include, but are not limited to, synchronizing the recordation of signals detected downhole with the firing of the signal source and processing the recorded signals to eliminate useless information. The methods present several techniques for true source signal recognition whereby actual signal information is extracted from the recordings of the receivers so that the ultimate stored data is compact and virtually 100% useful. This elimination of useless data conserves valuable telemetry time and/or enables longer operation of the apparatus before tripping out to retrieve stored data by using memory efficiently.

Abstract: A circuit for the reading of charges injected at its input (E) comprises a read MOS transistor (M1), the type of which conditions the polarity of the charges that the read circuit is capable of reading without getting blocked, and an integration capacitor (C) mounted between a first electrode of the drain-source pair of the read MOS transistor (M1) and a reference potential (VDR). The input of the circuit is at the second electrode of the drain-source pair of the read MOS transistor (M1). The injected charges must cross the read MOS transistor (M1) to be integrated by the capacitor (C). The read MOS transistor (M1) is controlled by a control voltage that varies in a manner that is substantially inversely proportional to the input voltage (Ve). The circuit has means (A2) to detect the arrival, at the input (E), of charges with a polarity opposite to the polarity of the charges that it is capable of reading and means (M2) for the imposing, on the input voltage, after a detection of this kind, of an equilibrium value (VDRN) equal or close to a basic value (Vb) that it takes between two successive operations of integrating charges with the desired polarity so as to prevent a prolonged blocking of the read MOS transistor (M1) at the arrival of charges with a desired polarity.

Title: Method and device for cooking and vacuum packing of mussels with microwaves
Inventor: HAAMER JOEL
IPC: A23L17/50
Filed: 1999-06-14
Granted: 2007-06-05
Abstract: The invention relates to a method and a device for cooking and vacuum packin g mussels with their shells and other foodstuffs by microwave heating so that they can be stored as chilled or frozen goods for an extended period. When mussels are vacuum packed, many of the shells often break, and moreover the subsequent cooking in water is t oo slow for the mussel meat to coagulate satisfactorily. The invention solves this problem by packing the product to be preserved, in the first place mussels, in a somewhat flexible plastic container which is sealed. On the top side of the container there is a venting hole which permits the escape of steam during boiling but which is sealed immediately as microwave heating ceases, whereupon a vacuum arises inside the container as the steam condenses. A vacuum packed and pasteurised product is thus obtained in one and the same operatio n.
