A plasma screen of the alternating type, comprising a plurality of elementary image dots, of which each dot is defined by electrodes which are perpendicular to each other, connected with circuits supplying addressing signals and maintain signals at each elementary image dot during operation, characterized in that each elementary image dot is defined by three parallel and coplanar electrodes (G,...

A process for the manufacture of articles from divided product such as powder by shaping this product and heat treatment. The process consists in adding a polysaccharide obtained by bacterial or fungal fermentation such as, advantageously, a xanthan gum, to the divided product and then shaping it by any known processes and subjecting the article thus formed to a heat treatment. The article ob...

A catalytically active powder, its preparation, and its use for activating insulating substrates to receive electrolessly deposited metal in a coherent metal layer are described. The powder of the invention comprises a plastic powder containing catalyzing/activating chemical compounds allowing that the acceleration of the catalyst is not carried out until the powder is melted down onto the substra...

A measurement circuit provides an output signal as a function of an input signal. The measurement circuit includes a charge generator which provides packets of charge as a function of the input signal to a measurement element. The measurement element measures the charge provided and provides a measurement signal as a function of the charge received. The measurement signal is coupled to a feedback ...

A system for measuring cyanides in a sample employs a photoillumination component for producing ultraviolet radiation to dissociate cyanides contained in an alkaline sample. The system includes filtering components interposed between the photoillumination components and an alkaline sample to be tested for passing lower frequency ultraviolet radiation to produce an irradiated sample in which cyanid...

A method of and apparatus for dynamically mechanically bonding together a plurality of laminae, at least one of which comprises thermoplastic material: for example, polyethylene. In one aspect of the invention the laminae are forwarded in face to face relation through a pressure biased nip between a patterned nip defining member and an opposing nip defining member (eg, a relief patterned cylinder ...

A tubular lining for lining passages is formed, such liner being constructed from a laminate comprising a resin absorbent layer and an impermeable skin. The laminate is wrapped to tubular form with the skin outermost and the free edges are butted together and are connected in this condition by a sewing operation. A sealing ribbon as applied over the sewing to seal the seam and stitching to prevent...
