  • Patent number: 7074293
    Abstract: A method improves the property of films including a release film and a protective film. After separating from the release film, the protective film is bonded with a TAC (Triacetyl Cellulose) film and then processed by coating, such as with an anti-reflecting coating, an anti-glaring coating and a surface hardening treatment, and by drying in an oven. The protective film is separated from the TAC film. The waste of material, which resulted from cracks, snaps and bends of the film, is avoided in the process. Furthermore, practice costs are low, and additional expensive apparatus or treatment are not necessary for a simplified procedure of the method.

  • Patent number: 7070669
    Abstract: An improved process for producing ceramic thick film array elements is provided. In this regard, ceramic elements are formed on a temporary, or printing, substrate by screen printing or other forming methods. The temporary, or printing, substrate is advantageously provided with a release layer. This makes it possible to release the printed and soft-baked ceramic elements from the temporary substrate and transfer the ceramic elements to the sintering substrate. The contemplated release technique takes advantage of the phase transition of a liquid, e.g. water, to transfer the elements to a sintering substrate. After sintering and electrode deposition, the ceramic element array is bonded to a target substrate. Then, the sintering substrate is removed to make the array available for implementation in a variety of suitable environments.

  • Patent number: 7070667
    Abstract: Tiles are installed on a vertical wall by employing an elongate, straight device that includes a spirit level. The device is positioned in overlying relation to the wall and rotated until it is horizontal as indicated by the spirit level. A plurality of longitudinally spaced and vertically staggered slots is formed in the device. Each slot receives a fastener so that the device can be secured to studs behind the wall. A row of tile supported by the device is then installed on the wall. The fasteners are removed after the tile installation is complete so that the device can be moved and re-used. Opposite ends of the device are configured to releasably engage a device of the same structure so that multiple devices can be linked together. An alternative embodiment is notched along its extent to provide utility in the context of convex and concave walls.

  • Patent number: 7070656
    Abstract: The invention provides apparatus for electrostatically coating a pharmaceutical tablet core with powdered coating material. The apparatus comprises a first rotary drum (12) on which a core is held in electrical isolation from its surroundings but at a potential differecne to earth by an electrode which contacts the core. The core is carried past a coating station B at which particles of powder having an opposite potential difference to earth are held in a tray (18). The surface of the drum is held at the same potential difference to earth as the powder particles. The powder is attracted to the core, and not to the drum, coating the exposed surface of the core. The drum carries the coated core past a fusing station C at which a heater fuses the powder to form a continuous film coating. The core is then turned and transferred onto a second drum (12?) where the other surface is coated in the same way.

  • Patent number: 7067010
    Abstract: The machine is an index spraying machine. The machine has five different stations. The first station is the load/unload station. At this station, work pieces are unloaded after they have been sprayed and new work pieces to be sprayed are loaded on. New pieces then move into the pre-heat station tunnel. A third station is the spraying area. In this area, the work pieces are sprayed. After being sprayed, the work pieces move in the area where they are heated to flash off the volatile fumes. Then they move to the fifth work station where they are cooled and finally they move back into the load/unload station. The spraying area in this machine is sealed to meet NEMA 7 standards. The air capture system cascades the air, thus lowering the air volume that passes through the thermal oxidizer.
