Date Aug. 8, 1991.A package blank is provided including a wrapping material and a substantially deformable inner material. The wrapping material consists of a resilient film having a sealed inner space. The inner material consists of particles accommodated within the sealed inner space. At least one article is surrounded by the package blank. During a package forming process, pressure is reduced within the inner space and the article is surrounded by the blank. The pressure reduction causes the wrapping material to tightly encircle the article, the inner material to be stiffened, and the particles to be substantially immobilized relative to each other. A stiffening plate included on a surface of the wrapping material is adapted to receive a piercing device during the package forming process. The piercing device penetrates the wrapping material and the stiffening plate and establishes a communication between the sealed inner space and a vacuum creating mechanism. A sealing member closes the communication upon removal of the piercing device.

Title: Graduated filter
Inventor: SANVIDO SAVERIO
IPC: G02B7/00
Filed: 1989-12-13
Granted: 1999-09-07
Abstract: A preferred embodiment of the graduated filter comprises two bearings for the rotary axles of the two filter discs. The rotary axles are driven by a motor via a belt drive. The belt drive comprises a double belt pulley at the drive shaft of the motor and two toothed belts which wrap around respective toothed-belt pulleys mounted at the rotary axles. Compared with known toothed-wheel gearing, the belt drive is less expensive, more practical, wear-resisting and lighter in weight. The plane of the intersecting axes of rotation of the rotary axles is slightly inclined with respect to the direction of the optical axis of the graduated filter. By virtue of the angular adjustment of the axes of rotation of the rotary axles of the two filter discs, it is rendered possible that the toothed belts snugly fit the running surfaces of the respective toothed-belt pulleys, so that the latter and the toothed belts are uniformly loaded, thus increasing service life thereof and ensuring constant transmission of force.
