Inventor: BUMPUS PATRICK D
IPC: D06M11/79
Filed: 1991-08-12
Abstract: A flame retardant or fire retardant preparation can be employed with fibrous material containing either cellulosic fibers, non-absorbent fibers, or blends thereof. The preparation is formed of an aqueous solution of ammonium sulfate, a metasilicate salt serving as binder, and ammonium phosphate (MAP or DAP). An ultraviolet inhibitor is preferably included in the solution. A wetting agent promotes penetration of the solution into cellulosic fibers. An ultraviolet fluorescent agent permits non-destructive testing of articles after treatment. For increased sensitivity, the preferred fluorescent agent is a substituted 2,2' disulfonic acid sodium salt.

Title: Process and circuitry for displaying radar echo signals.
Inventor: STURTZEL JORG FELIX
IPC: G01S7/22
Filed: 1991-09-16
Abstract: A process for displaying radar echo signals allows brightness modulation signal of the radar picture to be derived from the radar echo signal. In order to avoid brightness overmodulation in the case of flat, wide echo structures, and to improve detail recognition, the flat echo structures of extensive reflecting objects that appear on the radar picture are reproduced around their outer outlines (contour) with high intensity, whereas the inside of their surface is reproduced with a strongly reduced intensity. A highly contrasted image with a cartographic appearance is thus obtained, in which even smaller targets or targets with bad reflecting properties, thus lower intensity, can be very well recognized.

Abstract: Un dispositif de libération qui réagit à la pression hydrostatique peut être utilisé pour la fixation des équipements de sauvetage à un bateau et pour leur libération automatique au cas où le bateau s'abimerait en mer. Le dispositif comporte un boîtier (11) divisé par une membrane (13) en deux chambres (20, 22). Une première chambre (20) communique avec l'extérieur de sorte que la variation de pression agit sur la membrane (13) et la déforme. Un élément de fixation (40, 41, 42) s'étend dans la première chambre (20) où il est doté d'un dégagement (45) qui abrite en partie des billes disposées en saillie (46). Les billes (46) sont maintenues dans le dégagement par une coupelle (52) associée à la membrane (13) et servent à empêcher le retrait de l'élément en se bloquant contre un arrêt (48). Une pression accrue déforme la membrane (13) et écarte la coupelle (52) des billes (46). De cette manière les billes peuvent sortir du dégagement (45) et l'élément (40) (qui peut être relié aux équipements) est ainsi libéré du boîtier (11) (qui peut être solidaire du bateau).

Abstract: An optical waveguide (2) formed on one major surface of a substrate (1) made of a non-linear optical crystal. A periodic polarization inversion region (3) where each polarization inverts periodically along the waveguiding direction is formed in the optical waveguide. In the polarization inversion region, the inversion period of the polarization is made shorter gradually toward the light-emitting end (2b) of the optical waveguide from the light-incident end (2a) thereof. A pair of electrodes (5,6) facing each other via the optical waveguide are formed. A voltage is applied to the optical waveguide in the direction perpendicular to the waveguiding direction by those electrodes. An electric field produced in the optical waveguide by the applied voltage induces an electrooptical effect which allows the individual refractive indices of the fundamental wave and second harmonic to be changed. The allowable fundamental wavelength band can be shifted to the short wavelength side or long wavelength side of the fundamental wavelength in accordance with the level of the applied voltage.

Abstract: An assembly in which a rotating shaft (10) is supported by a magnetic bearing (11) has a back-up bearing (18), to support the shaft (10) in the event of failure of the magnetic bearing (11), the back-up bearing (18) comprising one or more constituent parts each including cylindrical rolling elements supported on a single raceway, or each part comprising a ball race with radially inner (26) and outer raceways (22). If a radially outer raceway (22) is provided it is secured to an anchorage, such as a housing (16). A layer of dry bearing material (24) is secured to rotate with the or each raceway (26) to be rotated by the shaft (10), the dry bearing material (24) having a surface (30) opposite to the shaft (10). 
     After any failure of the magnetic bearing (11) the shaft (10) is contacted by the layer of dry bearing material (24), and the rolling elements (20) are brought up to speed at a slower rate than otherwise would be the case, because of slipping of the shaft (10) relative to the dry bearing material (24). It is arranged that, by the time the back-up bearing (18) is rotating at the same speed as the shaft (10), the back-up bearing (18) is rotating at a speed not significantly greater than the maximum design speed for the rolling elements (20).

Abstract: An open topped container 1 has base supports 8 and 9 each of which consists of an upper U-shaped support bar 10 and a lower U-shaped support bar 11. The bars are pivotally mounted on opposed side walls 3 and 4 to be pivotal to a position in which they overlie the base 2 of the container or a position out of said overlying relationship. The support bars 10 and 11 can be selectively pivotted to provide column stacking of two similar containers or either of two depths for nest stacking those containers where the upper container is received within the lower container in a vertical column. For column stacking the upper bars 10 are pivotted to overlie the base 3 to support an overlying container. For nest stacking the bars 10 are pivotted out of overlying relationship with the base 2 so that an overlying container can be nested in a shallow condition in which it is supported on the bars 11 or in a deep condition where the bars 11 are displaced out of overlying relationship with the base 2. 
     In an alternative embodiment each of the base supports 8 and 9 can be provided by a single pivotally mounted support bar.

Abstract: A substrate for surface-enhanced analytical procedures, such substrates prepared for use in specific procedures to detect specific binding partner molecules, and a method for making them. The substrate is a body having a substrate surface on which there are randomly spaced apart metal islands. A continuous layer of coupling agent coats the islands and any intervening substrate surface. First binding partner molecules are bonded to the coupling agent. These are specifically attractive to specified second partner molecules for an analytical procedure for detecting the presence of, and perhaps the concentration of second partner molecules, or in some procedures, of a specified third binding partner molecule which becomes bonded to the second binding partner molecule. The thickness of the coupling agent layer is selected to improve the sensitivity of a given analytical procedure for detecting or measuring the specific binding partner molecule.
