Abstract: The present invention relates to a method of fabricating a boron nitride isolating rod essentially used for sheathed heating elements and rod obtained by this method. Method characterised in that it consists essentially, firstly, in performing multiple vertical pressings of the boron nitride in powder form, at least one stage of release of the pressure being provided between one of the pressings, then in proceeding to dehydrate the rod (1) obtained after the various pressings under a first vacuum, and finally in conditioning the dehydrated rod (1) by placing it in a neutral gas atmosphere with a low degree of ionisation, the sequence of these various steps making it possible to obtain a rod (1) with a density which is greater than or equal to 98% of the theoretical density and in respect of which the isolations and the dielectric rigidities are very high both in the cold and in the hot state. <IMAGE>

Abstract: The invention relates to a writing and drawing arrangement, referred to as a finger pen (2, 3, 4). We have clung to the traditional notion that pens or pencils must be rod-shaped in spite of the fact that this subjects the fine-motor function of the user to unnecessarily stringent demands. A study of the development of the fine-motor function of children proves that a semi-supine grip on rod-shaped pens or pencils can normally not be achieved out before the age of 6-7 years. The invention solves this problem by means of a finger pen (2, 3, 4), prone holding (1) of which is already possible at an age of 2-3 years, which generally makes possible its use in a manner which as regards the fine-motor function is simplified. Pen nib (5) projects from or in the vicinity of sensible centre of feeling (7) of writing/drawing finger (6) and is so angled that the point at which it contacts the writing/drawing surface will be seen by the user. Various alternatives of finger pen (2, 3, 4) are possible, e.g. of open type (2), closed type (3) or contoured shape (4). The invention applies mainly to writing/drawing while holding the pen in a prone position (1).

Abstract: A process and system for low NOx cogeneration to produce electricity and useful heat. Fuel and oxygen are provided to an internal combustion engine connected to drive an electric generator, to thereby generate electricity. An exhaust stream is recovered from the engine at a temperature of about 500 DEG  to 1000 DEG  F. which includes from about 6 to 15 percent oxygen. Fuel is added to the exhaust stream to create a fuel-rich mixture, the quantity of fuel being sufficient to react with the oxygen and reduce the NOx in said exhaust stream. The fuel-enriched stream is provided to an afterburner, and the fuel, NOx and available oxygen are reacted to provide a heated oxygen-depleted stream. The oxygen-depleted stream is cooled in a heat exchanger. Conversion oxygen is admixed with the cooled stream which is then passed over a catalyst bed under overall reducing conditions. NO is converted to NO2 at the forward end of the bed, and the NO2 then reacts on the remainder of the bed with excess combustibles. Air is added to the resulting stream from the catalyst bed to produce a cooled stream having a stoichiometric excess of oxygen, and the cooled stream is passed over an oxidizing catalyst bed to oxidize remaining combustibles. The resultant low NOx stream can then be provided for venting.

Abstract: Disposable absorbent articles such as baby diapers or adult incontinent briefs provided with a refastenable adhesive fastening system. The adhesive fastening system preferably comprises a pair of tape tabs each having an adhesive surface which during use is adhered to a landing member having an adherence surface which may comprise only the backsheet that has no reinforcement for strength against tearing or may comprise a reinforced backsheet.
