Title: Therapeutical system for transdermal delivery of levonorgestrel
Inventor: WOLFF HANS-MICHAEL
IPC: A61K9/70
Filed: 1998-07-02
Granted: 2005-06-21
Abstract: The invention relates to a physically and chemically stable therapeutical transdermal sytem (TTS) for transcutaneous delivery of levonorgestrel alone or further sex steroid hormones also over a long period.  The inventive system is characterized in that it has good fixation properties and comprises a matrix containing polymethacrylate-based steroid hormones to be fixed by contact. The invention also relates to a method for producing such a system, advantageously characterized in that it does not contain any solvent and preserves the active agents. The inventive TTS is characterized in that it is physically and chemically stable, has good fixation properties over long periods and delivers across the skin large amounts of active agents per surface unit. One advantage of the inventive method of production is that said active agents are as little exposed to temperature stress as possible, resulting in minimized degradation or decomposition reactions.

Abstract: Factors controlling the effect of cloud seeding were critically examined, and a new horizontal penetration seeding method using liquid homogenous ice nucleants at the lower level of the supercooled portion of clouds was invented to maximize the microphysics-dynamics interaction between the seeded ice crystal thermal and the supercooled cloud through optimal utilization of the phase change energy.  Cloud seeding tests showed a remarkable effect. This method allows the development of twin rotating horizontal cylinders of ice crystal thermal, which slowly rise, expand and entrain the supercooled cloud droplets to provide the supersaturated condition and time for the required growth of seeded ice crystals. When the thermal reaches the top of the cloud, it spreads horizontally while lowering the ice crystals of sufficiently large size and fall velocity resulting in an effective treatment of the existing and induced cloud volume for precipitation augmentation and the associated dynamic effect.      The seeding method and apparatus for the operation are claimed.

Granted: 2001-05-15
Abstract: A transmyocardial revascularization system including a plurality of inserts formed of a material to elicit a healing response in tissue of the myocardiu m and deployment instruments and associated components for deploying the inser ts into the wall of the myocardium. The inserts are arranged to be disposed within respective lumens or channels in the wall of the myocardium. The inserts can take various forms, e.g., be solid members, tubular members, or porous members, and may be resorbable, partially resorbable or non-resorbabl e. In some embodiments the inserts are arranged to be left in place within the channels in the wall of the myocardium to result in plural lumens which enab le blood to flow therethrough and into contiguous capillaries. The deployment instruments are arranged to pierce the tissue of the myocardium from either the endocardium or the epicardium to insert the inserts into the myocardium,  depending on the particular deployment instrument used. The deloyment instruments may make use of a stabilizing device to stabilize them during th e procedure of inserting the inserts into the myocardium. A controller may als o be provided as part of the system to coordinate the operation of the deployment instrument with the cardiac cycle. The formation of the lumens ca n be achieved either bythe inserts or by some other means, such as a piercing tip or an energy applicator forming a portion of the instrument. The inserts  may include one or more of pharmaceuticals, biologically active agents, radiopaque materials, etc.

Abstract: An explosion vent (10) for covering an opening (12) in an enclosure (14) subject to the built-up of pressure is disclosed. The explosion vent includes a peripheral flange (16) configured for attachment to the enclosure around the opening, a pressure relief panel (18) positioned within and hingedly connected to the flange, and a plurality of connectors or rupture tab assemblies (19) connecting the unhinged portion of the pressure relief panel to the flange. The connectors break when the enclosure is subjected to pressure build-up for permitting the panel to shift outwardly from the enclosure for uncovering the opening in the enclosure. Rivets (72) are provided for attaching the rupture tab assemblies (19) to the pressure relief panel (18) which function to provide additional panel support and minimize localized bending of the rupture tabs (21) forming a part of assemblies (19) when the explosion vent is subjected to vacuum conditions, but do not interfere with rupture of the tabs and opening of the panel at a relatively low burst pressure. The pressure relief panel has a plurality of domed sections (46-52) presenting at least one valley defining bridge (54-58) therebetween. The domed sections and bridges cooperate to stiffen the panel so that it more uniformly distributes force on the connectors, causing all of the connectors to break at approximately the same time so that the panel more consistently opens at a selected burst pressure level.

Title: Pneumatically assisted electrospray device with alternating pressure gradients for mass spectrometry
Inventor: YEE PETER P
IPC: H01J49/04
Filed: 1999-09-27
Granted: 2006-02-07
Abstract: An apparatus for producing gas-phase ions from a sample compound in a carrier liquid. The electrospray needle (or capillary) (100) of the present invention includes a central metal tube (102) which carries the liquid containing the sample compound. The central tube (102) is surrounded by a plurality of tubes (104) which transport a nebulizing gas. The nebulizing gas tubes are placed symmetrically around the outside of the liquid containing tube. The nebulizer of the present invention produces a symmetric, non-annular gas flow which has variations in pressure around the circumference of the central tube. The pressure variations of the nebulizing gas flow produce additional shear forces on the liquid emerging from the central tube. This assists in forming a uniform electrospray of droplets from the liquid at lower nebulizing gas flow rates, thereby reducing the disadvantageous effects of the higher gas flow rates used in the art. The symmetric arrangement of the nebulizing gas tube provides support for the central sample carrying tube, thereby reducing the alignment problems found in prior art devices, and enhancing uniformity of the electrospray.

Abstract: A method of determining the location of an unknown source (10) transmitting a signal to satellite relays (14 and 16) comprises receiving replicas of the signal from the relays at receivers (18). The receivers (18) also transmit and receive reference signals via respective relays (14 and 16). All signals are downconverted, digitised and correlated with one another in pairs using a correlation function including a term which compensates for time varying differential frequency offset (DFO).  Compensation for time varying differential time offset or time dilation is achieved by replicating or adding to signal samples and applying phase corrections. This procedure enables a correlation maximum and associated measurement results to be obtained despite the effects of relay satellite motion which mitigate against this. Results are used in a prior art geometrical technique to locate the unknown transmitter.
