A dental impression silicone composition comprising: (A) 100 parts by weight of an organopolysiloxane having at least two aliphatic unsaturated hydrocarbons in one molecule; (B) from 0.1 to 30 parts by weight of an organohydrogen polysiloxane having at least three hydrogen atoms directly bonded to the silicon atom in one molecule; (C) from 10 to 500 ppm, based on the total amount of the compo...

A photosensitive printing element having an overall layer of powder material and a process for making a flexographic printing plate from such an element are disclosed. The photosensitive element includes a support, a photopolymerizable layer, and a layer of powder material on the photopolymerizable layer. The layer of powder material can be opaque or transparent depending upon desired use.

Rate control in a stereoscopic digital video communication system is accomplished by modifying the quantization level of P or B-frame data in the enhancement layer depending on whether the frame is temporally predicted (from the same layer) or disparity predicted (from the opposite layer). The invention can maintain a consistent image quality by providing additional quantization bits for disparity...

Plants transformed with a gdhA gene and also with a gene used as a selectable marker provide a dual gene herbicide resistant and tolerance package. The transgenic plants and their progeny exhibit an expression cassette having transcription initiation and transcription termination regions functional in the plant cells, and a DNA sequence encoding the GDH enzyme. The expression cassette imparts a de...

Multiple thermal pulses are employed to regenerate segments of an adsorber bed simultaneously in thermal swing adsorption processes. The invention is particularly applicable to air purification as it helps to reduce purge flow and improve regeneration efficiency.

For accurately determining, in real time, the collapse of a thermoplastic workpiece (34) processed in a press, such as an ultrasonic welding apparatus (10) or a vibration welding apparatus (10), a two-phase method is used. In the calibration phase signals are generated which are responsive to the yielding or displacement of the movable press portion relative to the substantially stationary portion...

A wrapping apparatus whereby a wrapping medium (30) may be applied to an annular article, such as a coil of metal strip (46), so as to cover its inner surface as well as all its outer surfaces comprises a rigid loop structure that defines an endless T-sectioned track (16,17) and extends as a cantilever extending from a free standing columnar support (5,6). The columnar support (5,6) includes eleva...

It was found, surprisingly, that the undesirable mucilaginous precipitates on the resin filter are not formed whenever the anion exchangers used for the water treatment are doped with at least one platinum group metal.

The publication discloses a mega wind power station, which provides for large scale utilization of the wind power at a competitive price compared to other energy production forms. The wind power station (1) comprises more than one tower (3), having wind power units (2) one below the other. A special siting carrier (8) assembles the rotor, the gear, the generators and enables the accommodation on t...

A tool for use with a cartridge gun adapted to dispense a product from a cartridge, the tool having first and second nozzle members with a fluid passageway extending therethrough, the first and second nozzle members being rotatably moveable such that they may be moved through 180.degree. with respect to each other, the nozzle members having an arcuate configuration, and guide means to guide the di...

A door-forming part (9,10) of the on-board installation is via the vessel frame (11,11A,12,12A) connected with a number of guide arms (13-16), which are activated to be moved in their longitudinal extent (17,18).

The device (6) incorporates at least one component (7) with at least one curved surface, along which an elastic, adhesive material piece is guided on being fed into the device.

Method for oxidation of a pendant methyl moiety on an aromatic ring to the pendant aldehyde moiety. The reaction typically employs laccase and the diammonium salt of 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid), and is carried out in the presence of oxygen.
