Abstract: A nonwoven fabric is made from fibres comprising at least two thermoplastic polymers and a compatibilizer. One of the polymers is present as a dominant continuous phase and the other polymer(s) as a non-continuous phase or phases. The polymer of the non-continuous phase or phases has a melt temperature less than 30  DEG C below the melt temperature of the continuous phase. The polymer of the dominant phase may be polypropylene and the non-continuous phase may be polyamide.

Title: A reflector for a vehicular lamp and a method for the manufacture therof
Inventor: YAMAMOTO NORIMASA
IPC: F21Y101/00
Filed: 1996-02-19
Abstract: In a method of forming a reflector for a vehicle a reference parabola is drawn in a vertical plane containing a principal optical axis of a reflector. A reference point of a curve demarcating the right side of a peripheral region of the reflector is set in the horizontal plane containing the principal optical axis. A boundary line of the peripheral region, which is extended along a design line of an outer lens when viewed from the side of a vehicle lamp, is drawn. The end points of the boundary line, and the end points of the reference parabola are determined by an external frame defining outer lines of the reflector viewed from the front side thereof. Of those points, the associated ones are connected by circular arcs, to thereby form a curved surface. The peripheral region forms a part of the curved surface. A region of the reflector intersecting the principal optical axis and continuous to the peripheral region is shaped to have a paraboloid of revolution. A plurality of paraboloids of revolution with different focal distances are set for the peripheral region, to thereby determine intersecting lines where the peripheral region intersects the paraboloids of revolution. A plurality of reflecting steps are disposed on the peripheral region between the adjacent intersecting lines. The reflecting steps are defined by parts of the paraboloids of revolution. The reflector thus formed is also claimed per se.

Title: Complexes for fluorescent labelling with large stokes' shifts formed by coupling together at least two fluorochromes capable of resonance energy transfer
Inventor: WAGGONER ALAN S
IPC: C09B11/28
Filed: 1996-05-30
Abstract: The present invention provides low molecular weight fluorescent labelling complexes with large wavelength shifts between absorption of one dye in the complex and emission from another dye in the complex. These complexes can be used, for example, for multiparameter fluorescence cell analysis using a single excitation wavelength. The low molecular weight of the complex permits materials labelled with the complex to penetrate cell structures for use as probes. The labelling complexes are synthesised by covalently attaching through linkers to form donor-acceptor complexes. Resonance energy transfer from an excited donor to fluorescent acceptor provides wavelength shifts up to 300nm. The fluorescent labelling complexes preferably contain reactive groups for the labelling of functional groups on target compounds, such as derivatised oxy and deoxy polynucleic acids, antibodies, enzymes, lipids, carbohydrates, proteins and other materials. The complexes may contain functional groups permitting covalent reaction with materials containing reactive groups.

Title: Overhead projection transparency pockets and masks
Inventor: BUNZL JOHN
IPC: G03B21/132
Filed: 1997-12-19
Abstract: Apparatus for storage and projection of transparencies 5a in pockets 5 is arranged to facilitate placement and projection on a platen of an overhead projector A rear cover 1 may have a cut-out aperture 4 of an area which is slightly smaller than the area of a transparency 5a to form a mask. In use, the cover 1 is laid over the platen 6 and thus masks the area beyond the required projection zone of the transparency 5a and in particular masks side edges of the pocket 5. The transparency retaining pockets 5 maybe attached to the cover 1 by means of a first post 7 which, as is shown, is located spaced outwardly and downwardly from a corner of the aperture 4. Each one of the pockets 5 has a punched hole 7b in a corner position The pocket 5 can be moved from the position P pivotally about the post 7 and in the plane of the cover 1 so that, by anticlockwise rotation, the pocket 5 lies fully clear of the aperture 4 in position S. When a stack of pockets 5 is positioned over the post 7, they may all initially be in the anticlockwise rotated position S clear of the aperture 4 and each individual pocket may be selectively rotated clockwise to be positioned at P over the aperture 4 for projection. The pocket 5 may have means eg weld lines (91, fig 14), to locate and retain a transparency in a selected position. The pocket 5 may have longitudinal sides having masked areas (90, fig 14).

Title: Gamma ray density profiling for filling level measurement
Inventor: BYATT JOHN ANTHONY
IPC: G01F23/288
Filed: 1998-05-21
Abstract: In a density profile sensor 1 a spatially resolved density measurement (particularly determination of the position of the oil/water boundary 6c) is carried out using a plurality of gamma radiators 2 arranged vertically above one another and an elongate optically conducting scintillator 10. The vertical position of sensed gamma rays is determined from comparison of the delayed coincidence of the two portions of the scintillation flash 11  with the photo detector(s)and thence a density profile of the oil 6b and the water 6a is determined from gamma absorption. The scintillator can have photo detectors at both ends or one photo detector and a reflector. Calibration methods, important system parameters for configuring the sensor 1 and measures for reducing crosstalk between the gamma radiators 2 (eg shielding, energy discrimination of Compton scattered gamma rays and arrangements of multiple scintillators 10) are further specified.
