In a process for joining profiled rubber strips, esp. at corner areas of window seals, uncured rubber is vulcanised onto both cut ends of the strips which form a butt joint with each other. Process equipment includes a heated tool with two parts (3,4) holding press tools (23) between them. The lower press tool (23) has two profiled strip holders (27), the holder ends being open to each other with ...

R<1> = H or 1-3C alkyl; R<2> = linear or branched 1-6C alkylene, oxyalkylene or arylene; X = O or NH; R<3>-R<7> = at least 3 iodo substits., the other gps. being H, 1-6C alkyl or alkoxy, Cl, Br, OH, NH2, -N(1-6C alkyl)2 or -NH-CO-(1-6C alkyl); n = 1, 2 or 3. Also claimed are radiopaque (meth)acrylate polymers (II) obt...

Methods for the synthesis of 9-cis retinoids, novel intermediates and methods for the synthesis of cyclohexadienyne nitriles and 9-cis alkyl cisoid nitriles, as well as 9-cis retinoids made using such methods are provided.

The invention is a system for non-invasive microwave tomographic spectroscopy of tissue using a plurality of microwave emitter/receivers (16) spatially oriented to the tissue, an interface medium (106) placed between the emitter/receivers (16), a control subsystem (65) operably coupled to the plurality of microwave emitter/receivers (16) for selectively controlling power to the plurality of emitte...

Method of reduced temperature metallic vapor phase combustion for jet, turbine, diesel, fuel oil, and gasoline combustion systems. More particularly, it relates to methods and composition of metal-containing fuels comprised of enhanced combustion structure capable of increasing combustion burning velocity and reducing combustion temperature.

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 vehicle headlamp assembly for producing a passing beam pattern has a paraboloidal or divergent ellipsoidal reflector (10) with a focus (14). A bulb filament (24) is disposed completely behind the focus (14) and has no light shield interposed between the filament and the reflector so that a divergent light beam is reflected off the reflector (10). A lens element (30) has prism portions (A to C) w...

A method for treatment of periodontal disease is disclosed. The gingival tissue is separated from the tooth surface in an area where periodontal disease is present. A biocompatible, porous material such as expanded polytetrafluoroethylene capable of supporting ingrowth of gingival connective tissue and preventing apical migration of gingival epithelium is placed in a laminar relationship to a port...

Hardening materials are provided which show excellent kneading-processability and uniform filling property of their pastes and are controlable to moderate setting time. In addition, the pH of the neighborhood of the filled part immediately after filling into living body lies in a weakly basic region, and the materials are able to integrate into living hard tissue. The materials are made by combini...

The invention provides a process for preparing collagen sponge, the process comprising the steps of impregnating crosslinked collagen sponge with an aqueous solution of a hydrophilic organic solvent, freezing the sponge at a temperature of about -80 DEG C or lower, and vacuum-drying the sponge.

A leadfree plate-shaped roof flashing material comprises a sandwich structure in which a stress damping and stabilizing layer (1) of ductile material is completely covered on one side and at least partly covered on the other side by preferably metallic foil sheetings (2, 3), e.g. of aluminium foil, designed with densely positioned flattened folded sections (4) having such a form, e.g. as closed in...

A waste water purificn. process, in which intermediate clarification is effected between first and second activation stages and post-clarification is effected between the second activation stage and the sludge circuit, involves (a) operating the first activation stage aerobically or facultatively anaerobically mainly with prokaroytes in the functional biomass as an adsorption stage with a sludge l...

A floating assembly (10) cleans and oxygenates water (30) in lakes, rivers and other inland waters by ventilator suction action.
