Microcrack resistant composites are prepared by precoating and prepregging woven fabrics of poly(phenylene terephthalamide) fiber at low warp tension.

A method of analysing a visual image of a complex three dimensional object such as a plant, avoids misclassification of shadows as plant material. A colour video signal of plant material positioned against a background of substantially uniform colour is analysed to give colour coordinates for each pixel in three dimensional colour space. Each pixel is classified as representing background or plant...

A Very Large Hybrid Module (VLHM) for packaging electronic components provides a hermetic enclosure formed by a hermetic substrate on which the components are mounted together with a hermetic lid surrounding groups of the components. A second substrate outside the hermetic enclosure is utilized for providing connections between the electronic components.

The invention relates to safety razor units of the disposable type. The razor blade cartridge, which may house one or two blades, is connected via a swivel-type hinge to a handle. The blade cartridge and the handle engage by means of a snap-action closure means. The razor unit provides a good shaving comfort; it is simple and inexpensive in production.

The invention relates to implants, for use in human and in veterinary medicine. The novel implants form, after implantation, an integral structure with the surrounding tissues. The implants consist of a rigid core which is coated with a well adhering matrix, in which there are embedded collagen fibers, part of which protrude from the surface of said matrix. A wide variety of solid physiologically ...

The present invention relates to novel conjugates, methods for their production, pharmaceutical compositions and methods for delivering cytotoxic anthracyclines to a selected population of cells desired to be eliminated. The anthracycline conjugates comprise at least one anthracycline molecule linked to a ligand that is reactive with a cell population to be eliminated, the anthracycline having a k...

Carbon-carbon composites consisting of graphite fibers reinforcing a carbon matrix are protected from oxidation by a B2O3 glass coating which includes a refractory oxide to stabilize the viscosity of the glass. Precursors of B2O3 and the refractory oxide are dispersed into a resin, the resin is used to impregnate fibrous graphite or fibrous graphitizable material, the sheets are laid up as plies a...

An N-substituted benzamide of the formula (I) in which R1 represents hydrogen or alkyl, R2 represents halogenoalkyl with more than one carbon atom, or represents cycloalkyl which is substituted by halogen or halogenoalkyl and R3, R4, R5, R6 and R7 are identical or different and represent hydrogen, halogen, nitro, alkyl, halogenoalkyl, halogenoalkoxy or halogenoalkylthio, or represent ...

A vehicle mountable seismo-magnetic mine detonation system having apparatus, associable with a vehicle, for providing a seismic signal which, when sensed by a seismomagnetic mine, causes at least arming thereof when the vehicle is at at least a predetermined distance from the mine; and apparatus, associable with the vehicle, for modifying the magnetic field sensed by apparatus forming part of the ...

A device having a shutter windable around a spindle and especially adapted to close a bay or other opening by the unwinding of the shutter, the same having flexible side edges which project beyond the shutter plane and which are retained with reduced friction in substantially continuous guideways during the unwinding and winding up of the shutter, that shutter edges may disengage from their guidew...

A tube (2) with its ball (5) used in a horizontal or slightly inclined position is connected to a pipe (39) picking up pressure variations in a nasal respirator (53). The detection of the forward and backward movement of the ball at the level of the independent detection unit (10) surrounding the tube is transmitted by optical fibres (45) to an electronic control and alarm module (22). A...

A device is described for separating the fillets from fish rumps, in which cutting tools (2, 3 and 4), in each case consisting of pairs of circular blades, are used for cutting free the abdominal fins, the dorsal fins and the ribs or lateral extensions of the spines. The last-mentioned cutting tool (4) has in this case a double function, which is based on the fact that each cutting blade (7) of th...

An intravascular catheter (10) designed to apply a liquid medicament or other substance to a stenotic lesion as the blood vessel is undergoing dilatation to facilitate the restoration and long-term maintenance of patency to the blood vessel. It comprises three concentrically arranged flexible plastic tubes (12, 14, 16) and a pair of concentrically arranged expander members (22, 30) located at the ...

The invention relates to 6-oxopyrido(2,1-α) and (1,4)thiazino(3,4-a)(2)benzazepine-4-carboxylic acid derivatives and their preparation and also to intermediates which can be used in the preparation. The said derivatives have a pharmacological effect by inhibiting angiotensin converting enzyme and they can be used for treating hypertension. The novel compounds have the formula in which R an...

A four-diode bridge is positioned within the cavity of a Gunn diode oscillator. A subharmonic signal is applied to the diode bridge and the diode bridge couples an odd harmonic of the injected signal into the cavity. The cavity is thus caused to resonate at the odd harmonic of the injected signal. The injected signal can be changed using a frequency synthesizer in order to provide a microwave osci...
