Title: Auto-focusing correction for rotational acceleration effects on inverse synthetic aperture radar images
Inventor: FARMER MICHAEL EDWARD
IPC: G01S13/90
Filed: 1994-07-22
Granted: 2002-04-09
Abstract: Inverse synthetic aperture radar imaging systems that are used to image targets that undergo rotational accelerations are enhanced by signal processing techniques which provide correction factors to reduce the frequency-shift and frequency-stretch errors that occur due to such accelerations. A target scan is subdivided into a number of sub-apertures and a Fast Fourier Transfer (FFT) is performed on the data for each sub-aperture to provide associated frequency sub-images. The FFT is then subdivided in "sub-swaths" of amplitude versus frequency for a plurality of frequency bands. The change-of-frequency, or frequency shift, data between prominent scattering points of each sub-image are processed to provide a phase correction factor that incorporates range changes and translational acceleration distortions for additional scattering points other than the most prominent scattering point. A frequency-stretch correction factor that compensates for rotational acceleration distortion is also provided.

Abstract: Solvent pulping is practised using ethanol, methanol, formic acid, or the like by passing the organic solvent countercurrent to the cellulosic fibrous material (wood) being adjusted into paper pulp. The process may be batch or continuous. The pH of the process is relatively stable and neutral, and can be controlled to maintain the process generally neutral by removing the acids formed at the beginning of the cook, e.g. with spent solvent, and can be made more uniform by adding alkali to the wood just prior to the wood coming into countercurrent contact with the organic solvent. A catalyst, such as an earth-alkali metal salt or an organic base, may also be added to the wood to enhance dissolution of the ligning. The treated pulp is washed, and the solvent in the wash liquid from the washing stage may be separated by distillation. The pulp may be steamed prior to cooking. The lignin containing liquid (spent organic solvent) may also be distilled, with the organic solvent renturned to the cook, the water separated and reused, and the lignin combusted.

Abstract: A retaining net is made of wire rings which are interlooped when producing at least some of the rings while other rings that participate in the interlooping are prefabricated.  Such nets are used for protection against falling rocks, avalanches, and mud slides.  The interlooping rings are formed by feeding a wire (22) through a bending tool (15) to form several turns that interloop with at least two prefabricated rings (20A, 20B) that are held by suspender members (31) so that the rings (20 being formed extend crosswise to the prefabricated rings.  When the formation of a first row of interlooped rings is completed, that row is interlooped with a second row and so forth.  The interlooped ring structure provides a simple, cost effective construction method for strong retaining nets.

Title: Method for quantifying specific compound
Inventor: IKEDA SHIN
IPC: G01N27/30
Filed: 1995-04-05
Granted: 2000-05-09
Abstract: A biosensor for quantifying a specific compound has a reaction layer containing at least an enzyme, and an electrode system having a working electrode and a counter electrode formed on an insulating base plate; the biosensor detects the specific compound contained in a sample on the basis of an electrochemical response. In quantifying, the working electrode and the counter electrode are short-circuited before the voltage is applied therebetween. The short-circuiting eliminates measuring errors that may occur due to nonuniform dissolution of the reaction layer in a sample, and achieves highly reliable quantification of a specific compound.

Title: Substituted n-heteroaroylguanidines as inhibitors of na+/h+ exchange
Inventor: KLEEMANN HEINZ-WERNER
IPC: C07D307/68
Filed: 1995-04-10
Granted: 2008-10-21
Abstract: The invention relates to heteroaroylguanidines of the Formula I (see formula I) in which the substituents HA and R(1) to R(5) have the meanings given in claim 1. These compounds exhibit very good antiarrhythmic properties, as are important for treating diseases which occur, for example, in association with symptoms of oxygen deficiency. As a consequence of their pharmacological properties, the compounds are outstandingly suitable for use as antiarrhythmic pharmaceuticals possessing a cardioprotective component for the prophylaxis and treatment of infarction and for the treatment of angina pectoris, in connection with which they also inhibit or strongly reduce, in a preventive manner, the pathophysiological processes associated with the genesis of ischemically induced damage, in particular associated with the elicitation of ischemically induced cardiac arrhythmias. On account of their protective effects against pathological hypoxic, and ischemic situations, the compounds of the formula I according to the invention can, as a consequence of inhibiting the cellular Na+/H+ exchange mechanism, be used as pharmaceuticals for treating all acute or chronic damage elicited by ischemia, or diseases induced primarily or secondarily thereby. This is the case with regard to their use as pharmaceuticals for surgical interventions, for example in organ transplantations, where the compounds can be used both for protecting the organs in the donor prior to and during removal, for protecting organs which have been removed, for example when they are being treated with or stored in physiological bathing fluids, and when transferring the organs into the recipient. The compounds are likewise valuable protective pharmaceuticals to be used when carrying out angioplastic surgical interventions, for example on the heart or on peripheral vessels. In conformity with their ability to protect against ischemically induced damage, the compounds are also suitable for use as pharmaceuticals for the treatment of ischemias of the nervous system, in particular of the CNS, in connection with which they are suitable, for example, for the treatment of stroke or cerebral edema. Over and above this, the compounds of the formula I according to the invention are also suitable for use in the treatment of forms of shock, such as, for example, allergic, cardiogenic, hypovolemic and bacterial shock.

Abstract: In the case of over-tightening of the closure-cap on a beverage bottle (through turning in the wrong direction) there is the risk that, due to the high internal pressure, not only will the thread jump, but also that the cap will be ejected directly from the container. In order to avoid this risk, the invention proposes a screwable closure-cap with security against over-tightening. This cap possesses a ramp element (3) on the end of the thread oriented towards the cap-base, said ramp element being able to engage with the thread-start of the container mouth in the case of over-tightening of the closure-cap. As a result, the cap-wall in the area of the ramp element will be forced outwards in the case of over-tightening so that jumping of the thread in this region will be facilitated. In this way, jumping of the thread on one side only = on the ramp element side = will be achieved when over-tightening is continued, so that ejection of the closure-cap will not be possible. In a further embodiment of the invention, retention elements (7,8) are arranged in the region of the seal. As a result of over-tightening and subsequent deformation of the region of the seal, said retention elements will make contact with the container mouth and the sealing-line will be interrupted. As a result, the container will be vented prior to jumping of the thread.

Title: Pharmaceutically acceptable polymeric tissue coating
Inventor: HUBBELL JEFFREY A
IPC: C08L79/00
Filed: 1994-10-05
Granted: 2007-05-29
Abstract: Described herein is a multi-functional polymeric material for use in inhibit ing adhesion and immune recognition between cells and cells, cells and tissues, and tissues and tissues. One component of the poly meric material adsorbs well to cells or tissue, and the other component of the polymeric material does not adsorb well to tissues. A water -soluble polymer that does not bear charge (polynonion) and which is not poly(ethylene glycol) is used as the non-binding component. A water-soluble polymer that is positively charged at physiological pH (polycation) and which is not poly(L-lysine) is used as the tissue binding component. When the bi-functional polyme ric material contacts a tissue, the tissue-binding component binds and thus immo bilizes the attached non-binding component, which will t hen extend generally away from the tissue surface and sterically block the attac hment of other tissues. The method and compositions are useful in inhibiting formation of post-surgical adhesions, protecting damaged blood vessels from thrombosis and restenosis, and decreasing the extent of metastasis of attachment-dependent tumor cells.
