Abstract: A plastic tank is comprised of two parts, a base and a top, that are permanently joined to each other by welding at a circumferential joint formed by two mating flanges of the parts. The faying surfaces of the flanges of the top and base have portions in the shape of a hollow truncated cone. Fusion weld elements are captured on the faying surfaces of the flanges of the assembled parts, and the elements melted by internal heating of metal portions of the elements.

Abstract: The apparatus has a bending/cooling station mounted on a base. A tube clamping assembly is mounted on the base, movable towards and away from the bending/cooling station and including a tube clamping assembly and a tube rotation assembly. A tube heating assembly is mounted for movement between the bending/cooling station and the tube clamping assembly. Servomotors move the tube clamping assembly and the tube heating assembly, rotate the tube clamping assembly, and actuate bending at the bending/cooling station. The apparatus is controlled by PLC or PC-based programs, which effect movement via servomotors and control other parameters such as heating and cooling times and temperatures. Bending and cooling the tube at a first bend location, and heating the next desired bend location, take place in overlapping time windows, before advancing the tube to position the next desired bend location of the tube at the bending/cooling station.

Abstract: A flexible patch pump for controllable accurate subcutaneous delivery of one or more medicaments to a patient includes a laminated layered structure. The pump may have a rigid reservoir layer including a number of rigid reservoirs disposed in a flexible material; a flexible microfluidic layer including a compliant membrane for sealing the rigid reservoirs, a network of microfluidic channels connecting the rigid reservoirs, and a number of inlet and/or outlet valves corresponding to the rigid reservoirs; and a flexible-rigid electronic circuit layer including a number of individually-addressable actuators. In operation, the rigid reservoirs may contain medicament that is dispensed in precise volumes at appropriate times due, for example, to a pressure change in an addressed reservoir caused by displacement of the compliant membrane or other actuation element.

Abstract: The present invention is a method for manufacturing inflatable articles, or bladders for inflatable articles, that is time-efficient, simple, inexpensive and permits the uninterrupted manufacture of numerous and even customized article or bladder configurations and sizes, without expensive configuration-specific, metal tooling. The method includes the steps of applying a barrier material to a side of a first film, providing a second film with the first film so that the barrier material is disposed between the first and second films, adhering the first film to the second film so that the films are sealed together in areas except where the barrier material has been applied to form at least one inflatable compartment and sealed peripheral edge, and cutting along the sealed peripheral edge to form an inflatable article or bladder for use in an article of manufacture. The barrier material may be a paint, ink, paper or surface treatment that effectively prevents the first film from adhering to the second.

The inner circumferential sloping surface of the heating section (6) and the second electrode section (7b) are interconnected by an R-shaped second connecting portion (22). The first and second connecting portions (21)(22) are formed such that R becomes larger from the upper end to the lower end, where the upper portion is thin and the lower portion is thick. The thickness of an intermediate portion (6b) is smaller than the thicknesses of the first and second connecting portions (21)(22).

The process provides that two sheets of meltblown fiber fabric are produced on forming wire assemblies, cooled at a cooling area, and are then laminated on opposite sides of a sheet of spunbonded fibers using to form the laminated, nonwoven fabric.

Abstract: A method for manufacturing an underlay material (8) to be set under parquet or a laminate, the underlay material including a sheet material layer (1) and a flexible cellular plastic material layer (3) bonded under the sheet material layer, and a bottom surface of the cellular plastic layer being processed for providing an air space, whereby the bottom surface of the cellular plastic material layer (3) is processed by melting the cellular plastic material locally for providing an air space (9) and for simultaneously bonding the cellular plastic material layer to the sheet material layer (1). An underlay material manufactured by such a method is also described.

Abstract: Methods for modifying contours of substrate surfaces are disclosed. Methods include depositing filler material on a critical mating surface of a substrate so as to render the mating surface more mateable with a matching substrate. The filler material can be deposited within or around features or defects on the mating surface such that a final desired surface contour is achieved. In some cases, the final surface contour of the mating surface is planar. This can prevent gaps associated with the features or defects from forming between the substrate and the matching substrate when they are joined together. The final surface contour of the mating surface can be determined by comparing dimensions of the mating surface to dimensions of a reference surface. In some cases, ink jet printing techniques are used to deposit the filler material accurately in prescribed locations and with precise thickness control.

Abstract: An accommodating intraocular lens comprises a first lens component, a second lens component, and an adhesive between portions of the two lens components. The cured adhesive bonds the lens components to form a fluid chamber. The lens components are bonded to one another along a seam which extends circumferentially along at least a portion of the lens components. The lens components may comprise the same polymer material. The cured adhesive also comprises the polymer or a prepolymer of the polymer to provide increased strength. The polymer is hydratable such that the lens components and the cured adhesive therebetween can swell together to inhibit stresses between the lens components and the cured adhesive.

Abstract: An in-situ double vacuum debulk (DVD) composite repair system designed to produce partially or fully cured autoclave-quality hot-bond composite repairs on contoured structures. The system provides vacuum pressure for hot bond repairs to be performed on flat and contoured structures using one set-up capable of debulking (partially curing) and then fully curing composite repairs on composite and metallic aircraft structures. The use of in-situ DVD also eliminates handling of the patch/adhesive when transferring from an off-aircraft DVD chamber to the repair site on the aircraft. This can increase the probability of successful repairs because the possibility of contaminating and misaligning the adhesive and repair patch are eliminated.

Abstract: A method for implementing a channel (56) includes providing a preform (20) having a recess (22) therein and heating a channel implementation element (30?) to a temperature greater than a melting temperature of a material of the preform (20). An external contour of the channel implementation element (30?) at least regionally corresponds to an internal contour of the channel (56) to be implemented. The method then moves the heated channel implementation and/or the preform (20) in relation to one another so that the heated channel implementation element (56) at least regionally moves into the recess (22) in a moving-in direction. The material of the preform (20) is at least partially melted in a region around the recess (20) and is at least partially displaced by the channel implementation element (30?), wherein at least a part of the channel (56) to be implemented is thus implemented.
