Abstract: The present invention is related to the use of ethylene alkanoate-alkyl acrylate bipolymers with a high randomness monomers distribution, which are synthesized by semicontinuous emulsion polymerization process, characterized because it is carried out using slow addition rate of the pre-emulsion feeding ({dot over (q)}?0.009 kg·L?1·min?1), stabilized this last one by alkyl glycol ether type surfactants, at temperatures higher than 75° C. and with solids contents above 25 wt %, which avoids the formation of large sequences (blocks) of a same monomer. This structural characteristic gives the ethylene alkanoate-alkyl acrylate bipolymers a high efficiency as chemical agents for removal of complex water/crude oil emulsions of crude oil blends.

Abstract: The present disclosure relates to novel demulsifying agents obtained from the functionalization of random bipolymers based on alkyl acrylate and aminoalkyl acrylate with different acrylic derivatives, using the aza-Michael addition reaction. The amphoteric random acrylic bipolymers were evaluated as demulsifying agents for crude oils with API densities between 10 and 40° API, showing superior performance as breakers, coalescers and clarifiers than the non-functionalized acrylic bipolymer and a commercial formulation based on polyethers.

Abstract: A vehicle-mounted directed advertisement system and method enables a marketing user to configure an advertisement campaign, and display the advertisement, in the form of audio-visual digital content, from a vehicle-mounted electronic display that is driven by a driving user, and directed towards a targeted consumer in a target geographic marketing area. The advertisement is designed by the marketing user and directed towards the targeted consumer through the electronic display. The audio-visual content is stored on a server and communicated to the electronic display. The location of driving user's portable communication device is tracked and generates audio-visual content based on its position relative to a geographic fence marketing perimeter. The driving user is payed to mount the electronic display and navigate through the geographic fence, so as to engage a targeted consumer with the advertisement. A dynamic traffic message displays on the electronic display when a traffic event occurs.

Abstract: The invention concerns a free lighter-than-air aerostat comprising a structure (1, 3, 4, 5) symmetrical relative to a main axis (2), at least one main sealed pressurized chamber (16), one or several particle emitting thrusters (8), adapted to drive the aerostat in rotation in one direction about the main axis (2), one or several moving flaps (9) adapted to be set either in an active state wherein they brake the aerostat rotation, or in an inoperative state wherein they offer no substantial resistance to the aerostat rotation, and on-board control means (19) adapted to control the thrusters (8) and the flaps (9) to drive the aerostat in permanent rotation about the main axis (2), and in translation perpendicular to the main axis (2).

Abstract: A method of carding a fibrous feedstock to form a carded sliver uses a carding engine (10) having a main toothed wire cylinder (11), a taker-in (12), a doffer (13), and a series of flats (14) movable along a closed loop (15) having a working path (16) arranged alongside the outer periphery of the cylinder (11) between the taker-in (12) and the doffer (13) in order to carry out a carding operation on the feedstock in cooperation with the teeth of the rotating cylinder (11) and to remove waste or trash particles and short fibers from the feedstock, in which the cylinder (11) is driven to run at normal production speed giving a circumferential speed Y of e.g. 60,000 inches per minute whereas the linear speed X of the flats (14) is a substantially increased speed compared to normal running speeds e.g. at least 16 inches per minute, thereby to produce a sliver with surprisingly improved quality which can approach that of a carded, and subsequently semi-combed (scratch-combed) or combed sliver.

Abstract: Flat filaments or ribbons are deflected by a system of sheaves to converge the filaments to closing stations proximate to points at which the filaments are tangentially applied to helical surfaces of a central cylindrical core member. Successive sets of filament deflection sheaves stack the filaments into bundles or stacks which can be separated by spacer elements which are applied to a smooth core or the filaments can be inserted into helical grooves or slots in the core. Preferably, adjacent filaments forming each stack are guided to prevent contact or totally eliminate sliding friction until just prior to application in the core. The apparatus and method can be used to produce optical fiber cables, high pressure flexible composite pipes and the like in which the flat ribbons can be wound either within helical grooves formed within the core or about the cylindrical surface of a smooth core.

Abstract: Fiber optic filaments or ribbons are deflected by a system of sheaves to converge at final filament deflection sheaves which direct the filaments along the longitudinal direction of an assembly table. Successive sets of filament deflection sheaves stack the filaments into bundles which are separated by spacer elements which are likewise guided to the assembly table. Sensors at the final sheaves monitor the tensions in both the filaments and separators and a controller is used to adjust the tensions to compensate for frictional variations upstream of the final sheaves. The table is positioned at an angle to the machine axis so that the stacked filament bundles and separators can be wound about a rotating core by being drawn along the table by the rotating core for staggered and tangential application of the filaments about the core at the downstream end of the table.

Abstract: This invention relates to a bobbin sorting and batch transfer apparatus which can collect a predetermined number of bobbins from vertically stacked storage racks each of which has a discharge port. A carriage is provided on which there are mounted one or more guide elements including vertical guides which can be juxtaposed proximate to the discharge ports. A chain drive bearing rollers is arranged to form holding bins or compartments which can be advanced in a planetary motion along the various guides. The rollers are spaced from the vertical guides to maintain the bobbins in equilibrium by arranging same to roll against the vertical guides, the rollers urging the bobbins to move through a closed loop path which can position any holding bin or compartment into proximate opposition to any discharge port in a given column of racks.

Abstract: This is disclosed a yarn re-structuring method and apparatus for modifying the structure of a spun yarn in order to improve its properties, in which the yarn is subjected to the action of successive false twisters in order to impart a permanent modification to the structure of the yarn, in which there is a tandem arrangement of first and second oppositely acting false twisters, with the first false twister acting to at least partially unwind the origianl twist in the yarn and the second false twister acting at least partly to restore or to increase the original twist in the yarn. This action on the spun yarn improves the properties of softness and bulkiness, while retaining acceptable performance of the yarn in other characteristics.

Abstract: An apparatus is described for storing and dispensing elongate flat strip material for use with rotating machinery, such as that used to produce helically wound interlocked flexible pipe. The strip material is fed from an external payoff or supply reel and guided by an inlet guide roller to feed the advancing strip tangentially onto a series of storage guide rollers which are spaced from each other about a circular path concentric with the machine axis. The strip is maintained under tension and is wound onto the storage guide rollers to provide a reservoir of strip material arranged in a single row of substantially circular overlappping convolutions concentrically arranged about the machine axis.

Abstract: A method and apparatus for modifying a spun yarn includes first storage or processing equipment for the yarn, subsequent storage or processing equipment for the yarn spaced some distance from the first storage or processing equipment, a path of travel for the yarn defined between the two sets of equipment, and a false untwister device located along said path of travel for imparting a false untwisting process to the yarn, the yarn subsequently reverting at least partly to the true twist originally present in the yarn, whereby the resulting yarn structure has a very much softer handle than was present prior to the false untwisting step.

Abstract: Textile slivers tend to loose their cohesion when travelling over long distances from one piece of storage or processing equipment to another such piece of equipment. This problem is overcome by subjecting the sliver to a false twisting process during its travel, desirably by a pneumatic false twister located immediately adjacent to the sliver-receiving equipment.

Abstract: An apparatus and method are described for producing compact stranded conductors on single and double twist machines. This is achieved by preshaping and metering the preshaped wires to have generally sectored cross-sectional profiled complementary configurations and positioning and orienting the preshaped wires to substantially correspond to their positions and orientations in relation to the core wire in the final compact twisted conductor. The wires are metered to a double twist strander which is used to initially twist the preshaped wires about the core wire in a generally loose construction, and these wires are subsequently locked into abutment against each other when imparted a second twist to form the compact composite conductor.
