Sepn. of different scrap plastics by flotation - includes sepg. pelletised plastic in fluid-contg. tank with high energy stirrer, for e.g. polystyrene

Agglomerations of small plastic particles, esp. film and adherence of air bubbles is detrimental to sepn. quality. High energy stirrer is used to create turbulence to break up the agglomerations and release air bubbles. Actual sepn. of material occurs when the stirrer is switched off. Lighter material rises to the surface of the fluid and heavier material falls to the bottom. Appts. for sepn. comprises tank with high energy stirrer, outlet valve for heavier material in the base and overflow trough for removing lighter material at the surface. Process fluid is recirculated via valve producing laminar flow into the tank. USE/ADVANTAGE - The process separates different types of scrap plastic e.g. polystyrene, polyvinyl chloride, polyethylene from each other and improves purity of separation by breaking-up agglomerations and removing adhering air bubbles.

Producing a workpiece prototype

The mould material is removed after a required number of repetitions of the above two steps. Alternatively thin layers of a workpiece material is applied onto a carrier structure. The layers are provided with contour lines and cutouts or grooves which subsequently are filled with a mould material. After a required number of repetitions of these steps the mould material is removed.

Process for producing polystyrene foam boards

A process for producing a drainage board and a lathing board is described. For this purpose, after selective comminution, fragments of polystyrene foam scrap are softened in a press which can be heated by steam and are compressed to form a slab essentially in the form of a right parallelepiped. The slab, which obtains numerous voids if compression is low, is cut up into drainage boards once it has cooled. Polystyrene foam slabs produced by compressing by about 1/3 are cut up thermally, whilst still in the warm state, into lathing boards, the fissured surface of which forms a base surface to which a plaster can adhere.

Method of welding thermoplastic substrates with microwave frequencies

Microwave frequencies in the range of 0.5 GHz to 10 GHz are used to weld thermoplastic substrates by interposing a carrier strip. The strip is formed of a polymer carrier which is miscible in the substrates. Electrically conductive submicron carbon black susceptor particles are chosen with specified properties such that they generate enough heat within a specified time to produce a weld in which the heat generated is confined to the weld zone. The resulting weld is such that the welded assembly has essentially the same dimensions as the clamped assembly. Glass fiber reinforced substrates are welded without breaking glass fibers in the weld zone. Lap strength of welded substrates is greater than that of substrates joined by prior art methods, whether by welding or adhesive bonding. Articles microwave welded in accordance with the invention are useful for manufacturing and repairing vehicle components such as automobile bumpers and dashboards and other structural parts of automobiles, aircraft, and spacecraft.

Temperature-controlled induction heating of polymeric materials

The present invention provides new polymer induction bonding technology. Induction heating technologies are utilized to weld, forge, bond or set polymer materials. The invention provides controlled-temperature induction heating of polymeric materials by mixing ferromagnetic particles in the polymer to be heated. Temperature control is obtained by selecting ferromagnetic particles with a specific Curie temperature. The ferromagnetic particles (13,83) will heat up in an induction field, through hysteresis losses, until they reach their Curie temperature. At that point, heat generation through hysteresis loss ceases. This invention is applicable to bonding thermoplastic materials, wherein only the area to be heated has ferromagnetic particles in it; bonding of thermoset composites (17), which have been processed with a layer of thermoplastic material (19) on one side; curing of thermoset adhesives or composite resins; or consolidating thermoplastic composites.

Measuring laser light transmissivity in a to-be-welded region of a work piece

Methods for measuring laser light transmissivity of a specific position in a work piece prior to the work piece undergoing laser welding at the specific position with a laser beam having a specific welding wavelength. To obtain a baseline measurement reading, a laser light source projects a laser beam at the welding wavelength directly into a detector. Thereafter, the work piece becomes suspended between the laser light source and detector whereby an output of the detector now corresponds to a work piece measurement reading. Differences between the two readings reveal whether the work piece will yield a satisfactory weld at the specific position when later welded by a laser beam at the welding wavelength. Preferred work pieces include inkjet printhead lids and bodies.

Patent JPS6249850B2

A process for joining a first kind of synthetic resin to a second kind of synthetic resin includes several steps. A first step is providing the first kind of synthetic resin, which may include fillers, e.g., glass fibers. A second step is setting a second contact surface of the second kind of synthetic resin on a first contact surface of the first kind of synthetic resin. A third step is exposing an outer surface of the second kind of synthetic resin to a laser beam. The second kind of synthetic resin transmits the laser beam to the first kind of synthetic resin, which stores up heat of the laser beam. The second contact surface of the second kind of synthetic resin and the first contact surface of the first kind of synthetic resin are melted by the heat of the laser beam. A plurality of projections and a plurality of recesses are formed on both the first contact surface of the first kind of synthetic resin and the second contact surface of the second kind of synthetic resin. A plurality of the projections of the first kind of synthetic resin engage with a plurality of the recesses of the second kind of synthetic resin. If fillers are provided, at least some of the will extend between the first and second synthetic resins. Accordingly, the second kind of synthetic resin is securely joined to the first kind of synthetic resin.

Cross directional zoned bicomponent films, film laminates, and systems and methods for manufacture of the same

Coextruded films provide cross directional zoned multiple components side-by-side to one another. Systems and methods relate to coextruding such films. During coextrusion, a first polymer conjoins with a second polymer while a temperature differential is maintained between the first and second polymers. This temperature differential is selected to reduce a difference between the viscosities of the first and second polymers making the viscosity of the first polymer close enough to the viscosity of the second polymer to avoid separation upon coextrusion. Further, the films may form a layer in subsequent lamination to other material layers.
