Abstract: A composite is provided, comprising a substrate and a film on the substrate. The film has an RMS surface roughness of 25 nm to 500 nm, a film coverage of 25% to 60%, a surface energy of less than70 dyne/cm; and a durability of 10 to 5000 microNewtons. Depending on the particular environment in which the film is to be used, a durability of 10 to 500 microNewtons may be preferred. A film thickness 3 to 100 times the RMS surface roughness of the film is preferred.

Abstract: A wet connect arrangement for communication beyond obstructions in a wellbore such as gravel packs and lateral junctions, among others. The arrangement employs communication line at first and second tubulars and annular or part annular communication pathways between the lines when the first and second tubulars are in operable position.

Abstract: A self-supported cylindrical corrugated filter (30) having arcuate side walls (34, 36) having over-lapping folded flaps which are non-adhesively joined i.e. by ultrasonic welding to provide a self-supported filter and a method of preparing the self-supported cylindrical corrugated air filter by using an ultrasonically weldable air filter blank that is corrugated to form a substantially cylindrical air filter (30) having two arcuate side walls (34, 36) with a plurality of open corrugation ends, folding the open corrugation ends to provide overlapping side wall flaps, and ultrasonically welding the overlapping side wall flaps to provide the self-supported cylindrical corrugated air filter and to provide the ultrasonically weldable air filter blank that can be corrugated.

Abstract: A high-tech doll produces human-like expressions, recognizes words, and is able to carry on a conversation with a living person, as example, addresses time based subjects, such as the food to eat at various times of the day, and expresses attitudes, emulating a living child. A child player acquires an emotional bond to the doll whilst the doll appears to bond to the child. The doll exhibits facial expressions produced concurrently with spoken words or separately to provide body language, representing emotions, such as happiness, sadness, grief, surprise, delight, curiosity, and so on, reinforcing the emulation of a living child. Additional features add to the play.

Abstract: A dual antenna transmitter includes a diversity encoding module that receives a data stream and provides a pair of encoded data streams selected to cause generation of overlapping symbols that provide substantially constant signal power to a receiver when the first and second antennas are unobstructed from the receiver. The diversity encoding module may compensate for the state retention of standard modulators thereby enabling the implementation of the Alamouti transmit diversity scheme. A wireless receiver capable of receiving data transmitted from the aforementioned transmitter includes a metric extraction module that repetitively extracts a metric from a transmitted signal at a selected rate to provide a first and a second metric stream, the first metric stream comprising data that is time offset from data in the second metric stream, the time offset corresponding to a differential time delay to the receiver for symbols emitted from the transmitter antennas.

Abstract: A wet connect arrangement for communication beyond obstructions in a wellbore such as gravel packs and lateral junctions, among others.

Abstract: Compositions for generating a cooked flavor in a foodstuff, comprising specified flavor precursors that react on heating to generate the flavor and maintain a reactive association after inclusion in the foodstuff. The compositions may include combination of a sulphur source, e.g. hydrogen sulphide, methane thiol, a sulfur-containing amino acid, thiamine, cystine, sodium sulphide, ammonium sulphide, ammonium polysulphide, onions, garlic, shallots, eggs, methionine, and mixtures thereof, and at least one reductone, e.g. a furanone, a ketone, a pyrone, an aldehyde, a carbonyl compound, isomaltol, maltol, pyruvaldehyde, hydroxyacetone, 3-deoxyglucosone, 5-hydroxy-5,6-dihydromaltol, 2,3-butanedione, 3-hydroxy-2-butanone, a process flavor, cooked vegetable concentrates, soy sauce, and mixtures thereof.

Abstract: An emergency overall suit, for protection of a person against exposure in water comprises a single garment with inner and outer layers, water-excluding seals at the ankle, wrist and neck portions and small vents at the extremities of the legs and arms of the suit to admit air and water to the space between the layers.
