Patent NO-177893-C (NO)
Inventor: EHMIG GERHARD
IPC: B25C1/14
Filed: 1991-07-16
Abstract: The powder-actuated fastener driving tool has a barrel (11) and a breechblock (17) which are axially displaceable in a housing (1). Provided on the housing (1), on the one hand, and on the barrel (11) and on the breechblock (17), on the other hand, are mutually co-operating stops (3a, 17e) and shoulders (8b, 11e), which first limit the displacement of the barrel (11) and, after a further displacement path, the displacement of the breechblock (17) counter to the driving direction. A free space, which permits the supply, normal to the barrel axis, of propelling charges (15), in particular in magazines, thereby results between the barrel (11) and breechblock (17).

Filed: 1993-02-12
Abstract: There are described benzoylguanidines of the formula I <IMAGE> where R(1) is equal to R(4)-SOm or R(5)R(6)N-SO2-, where R(4) and R(5) are equal to alk(en)yl, -CnH2n-R(7), and where R(7) is equal to cycloalkyl or phenyl, where R(5) also denotes H, R(6) is equal to H or C1-C4-alkyl, R(2) is hydrogen, halogen, alkyl, -O-(CH2)mCpF2p+1, -X-R(10), where X is equal to O, S, NR(11), R(10) is equal to H, (cyclo)alkyl(methyl), -CnH2n-R(12) where R(12) is equal to phenyl, R(3), inter alia, is defined as R(1),  and their pharmaceutically tolerable salts. The compounds I are prepared by reaction of compounds of the formula II <IMAGE> in which L represents a leaving group which can be easily substituted nucleophilically, with guanidine. Compounds I are outstandingly suitable as antiarrhythmic medicaments having a cardioprotective component for infarct prophylaxis and infract treatment and for the treatment of angina pectoris, where they also preventively inhibit or strongly decrease the pathophysiological processes during the formation of ischaemically induced damage. They are moreover distinguished by a strong inhibitory action on cell proliferation. They can therefore be used as antiatherosclerotics, agents against diabetic late complications, cancers, fibrotic disorders such as pulmonary fibrosis, fibrosis of the liver or fibrosis of the kidneys. They are effective inhibitors of the cellular sodium/protons antiporter (Na<+>/H<+> exchanger).

The labeled biological agents can also be used to detect normal, benign hyperplastic, and cancerous prostate epithelial cells or portions thereof. They also can be used alone or bound to a substance effective to ablate or kill such cells as a therapy for prostate or other cancers. Also disclosed are four hybridoma cell lines, each of which produces a monoclonal antibody recognizing extracellular domains of prostate specific membrane antigens of normal, benign hyperplastic, and cancerous prostate epithelial cells or portions thereof.

Title: Variable reluctance rotation sensor
Inventor: PAWLAK ANDRZEJ M
IPC: G01D5/245
Filed: 1990-08-21
Granted: 1994-11-22
Abstract: A variable reluctance rotation sensor comprises a rotatable magnetic toothed wheel adjacent a fixed magnetic pickup assembly.  The pickup assembly comprises a pair of permanent magnets, each with a similar pole adjacent the wheel and separated circumferentially by the arc between a tooth and a non-adjacent slot.  A magnetic flux member with a coil joins the other poles of the magnets in series opposed relationship and extends in close proximity to the toothed wheel to establish separate flux loops for each magnet distributed along the coil.  The flux loops are spatially determined by the teeth and slots between the permanent magnets, so that they fluctuate circumferentially and generate an electrical signal in the coil with wheel rotation by variation of the flux linkages to individual turns of the coil.  The sensor thus uses spatial flux changes to produce a rotation signal at very low rotational speeds with a larger air gap than that of conventional sensors.

Title: Method and apparatus for measuring and controlling the level of hormones in an animal circulatory system
Inventor: KEPPEL WILLIAM
IPC: G01N33/74
Filed: 1990-11-20
Granted: 1999-08-17
Abstract: A method and apparatus for measuring and controlling the level of a selected hormone in the circulatory system of an animal. The relationship between the level of a hormone, such as the immune-regulating cylokine IL-1, in the blood stream of an animal and application of sensory stimuli to the animal is determined by periodically taking discrete samples of the animal's blood while the stimuli are applied, measuring the levels of the hormone in the discrete samples, and correlating these levels with the application of the stimuli. Thereafter, the level of the hormone is controlled by applying to the subject those stimuli that have been found to produce a desired effect on the level of the hormone in the blood.      Biofeedback training and relaxation techniques are used to increase the effectiveness of the method and apparatus.

Granted: 2002-11-12
Abstract: The present invention relates to novel chimeric fibroblast growth factors (FGF) wherein the alanine at amino acid 3 and serine 5 of native human recombinant basic fibroblast growth factor are replaced with glutamic acid. The N-terminus sequence of the present chimeric FGFs identify homology with that of human acidic fibroblast growth factor. The mitogenic properties of the native human recombinant basic FGF are exhibited by the present chimeric FGFs, and they are efficiently expressed in E. coli at significantly greater yields that previously reported. Novel variants of this new glu3,5 basic fibroblast growth factor, such as those in which cysteine 78 and cysteine 96 are replaced, e.g., with serine or other amino acids, to produce stabilized versions of the glu3,5 basic FGF and eliminate disulfide scrambled forms, are also described.

IPC: H01R13/646
Filed: 1992-08-25
Granted: 2005-07-12
Abstract: A high frequency applicator for energizing electrode-less lamps is described. The applicators are end cups electrically attached to the ends of phased feed points of a planar transmission line, and facing each other so as to form a gap between the end cups.
