A method of manufacturing a particle-bonded nonwoven liner material (30) having antistatic and laminating properties whereby binder particles of thermoplastic material are precipitated from a water-based solution (34) by the addition of a precipitant having antistatic properties, preferably a di-ethyl sulfate quaternary of a complex cyclic amine. When the precipitant is added to a water-based disp...

A file directory structure generator and retrieval tool for use in a computer network is disclosed. The computer network comprises an output device, a local memory (18), a shared memory (19), and a local processor operating according to an operating system (8) and an application program. The local memory (18) and the shared memory (19) store files in a directory structure. Each file and level in t...

The present invention relates to unexpected or surprising discoveries in the field of biodegradable, water-dispersible formulations and materials and methods for influencing their rate of dispersibility in water. In particular, the present invention relates to the unexpected discovery that the inclusion of effective amounts of short length cellulose fibers dispersed throughout a water soluble cell...

This invention consists of two elements, i.e. 1) the production of a composite fiber sheet material, and 2) the processing of this material. 1) Production of a composite fiber sheet material: (1) a base cloth-forming rear side portion contains shrinkable fiber or fiber capable of being fulled. (2) An outer side-forming portion contains natural vegetable fiber. (3) The compounding of these outer an...

Die Erfindung betrifft ein Verfahren zur Herstellung einer stabilisierten, wäßrigen Alkalitetrathiocarbonatlösung durch Umsetzung mindestens eines Alkalidisulfids mit Schwefelkohlenstoff (CS2) in wäßriger Lösung, wobei in einer ersten Stufe elementarer Schwefel mit einer 5 bis 55 gewichtsprozentigen wäßrigen Alkalihyroxidlösung in einem Molverhältnis von Schwefel zu Alkalihydroxid (berechnet als F...

In a process for lacquering the phosphor layer on the bowl of a colour display tube (colour picture tube) screen, the following steps are performed: - the phosphor layer is first pre-wetted, - a first aqueous dispersion of a lacquer is applied to the pre-wetted phosphor layer, - said first dispersion is completely dried and heated to above the film-forming temperature of the lacquer in order t...

Compositions of coreactant resins, such as an epoxy resin, and polyanhydrides that contain non-cyclic anhydride moieties are cured to provide coatings that have good exterior durability. Preferred high molecular weight polyanhydrides contain a central polymer moiety that has no more than about 25 weight percent repeating units derived from unsaturated aliphatic hydrocarbon monomers. In other prefe...

The surface of a substrate material may be permanently modified so as to develop a microscopically smooth, biocompatible surface thereon. A biocompatible polymeric material may be covalently grafted to the surface of the substrate material by radio frequency plasma-induced grafting. The biocompatible polymeric material is preferably the same as the substrate material but may be different. Before g...

Electrically conductive and static dissipative materials (14), and methods of manufacturing the materials, are disclosed. Unlike existing conductive films or webs, the present invention includes discrete electrically conductive fibers (62) dispensed to form a network principally at or near the surface of a polyvinyl chloride (PVC) or other substrate (58). The fibers are typically, but need not be,...

The object is to create a method and a circuit arrangement for coding marking means in a contactless manner and to ensure a wide variety of applications in technical processes. The object is achieved by designing n switchable passive resonators (1) with the respectively assigned detection frequencies and burn-out frequencies as an array and by coding the n resonators in a specifically contactless ...

PURPOSE:To improve performance by eliminating the need for clearing other operand to '0' beforehand, and operating the arithmetic for sum up of only one operand of a vector register with a sum arithmetic instruction. CONSTITUTION:A first operand and a second operand are accommodated into a vector register 1. An arithmetic frequency identifying circuit 7, when the sum up arithmetic of only one side...

In a FLIR target detection system, true targets (52) are isolated from potential false target indications produced by background clutter through the use of a connectivity algorithm which attempts to find around each potential target (52) a closed path (65) of lower (or higher) intensity without exceeding a predetermined distance from the centroid (64) of the potential target. If the attempt is suc...

A three-pin BS 1363 plug comprises: a base A; a lid B slidable on the base A and engaging stops D of the base A; and a lever R pivoted at P to the base and having an extension F abutting the lid B at C, releasably to prevent removal of the lid. The lever R may he latched to the base A to prevent inadvertent release of the lid B, figs 3 to 5 (not shown).

In a hand-held video camera lens barrel 1 is pivotable with respect to supporting body 3. Image blur induced by shaking the camera is corrected by driving the lens barrel 1 to compensate for the measured angular displacement and velocity of the lens barrel. Video signals from imager 2 (eg CCD) are fed to motion vector detecting circuit 12; from this motion detected in the image is used to determin...
