Title: Rotary compressor which unifyies blade and roller
Inventor: SOTOYAMA TOSHIYUKI
IPC: F04C18/22
Filed: 1993-03-20
Granted: 1995-08-01
Abstract: The present invention relates to a rotary compressor which unifies the blade (8) which partitions the cylinder chamber (41) inside the cylinder into compressor chamber (X) and inlet chamber (Y) with the roller with the blade protruding beyond the radial direction, and disposes in the cylinder (4) a cyl-indric supportor (11) having a receiving groove to receive the tip portion of the blade (8) rotatingly. The said roller (7) is rotated relatively against the eccentric shaft of the drive shaft (22) which is engaged with the roller (7) and always supplied with lubricant oil. Thus relative movement of the blade (8) and ro ller (7) disappears, the power loss caused by friction is diminished, and the gas leakage from the rear room of blade (8) to inlet chamber (Y) and compression chamber (X) can be eliminated, the volume efficiency and indicating efficiency can be enhanced by diminishing the gas leakage from the compressor chamber (X) to the inlet chamber (Y).

Patent TW-403800-B (TW)
Title: Cellulosic web with a contaminant barrier or trap
Inventor: WOOD WILLARD E
IPC: B29C48/10
Filed: 1997-03-20
Granted: 2000-09-01
Abstract: Rigid or semi-rigid cellulosic sheeting known as chipboard also known as cardboard or heavy paperboard consists of sheeted materials that are comprised of bonded, randomly averted small discrete fibers. The fibers are largely cellulosic in nature and are held together by secondary bonds which are typically hydrogen bonds. However, active bonding agents can also be used. Such materials are commonly used in packaging applications and in certain packaging applications can require barrier or trap properties. Contaminants present in either an ambient environment or present in recycled cellulosic materials used in manufacturing the paperboard can act as a source of contamination of packaging contents. Such materials from the ambient environment or from the interior of the paperboard can be trapped in the paperboard using a trap material comprising a cyclodextrin material. Alpha, beta or gamma cyclodextrins can be used as a barrier or trap material in the paperboard. The structure of the paperboard can comprise a single layer of paperboard with a coating containing cyclodextrin, the paperboard can have the cyclodextrin material dispersed throughout the paperboard material or coated on the individual fibers prior to paperboard formation. Additionally, the paperboard can be laminated with a single layer of a thermoplastic resin material containing the cyclodextrin material. Further, a laminate structure comprising at least one layer of a paperboard material with at least one other layer comprising a film or other paperboard material can be used, at least one layer in the laminate containing the active cyclodextrin barrier or trap material. The cyclodextrin material can be dispersed into the paperboard material as free cyclodextrin, derivatized cyclodextrin, or can be combined with the paperboard in the form of cyclodextrin in or on a carrier material. The cyclodextrin can be carried in or on a carrier material by coating a carrier particulate fiber or film with the cyclodextrin material. Further, the cyclodextrin can be dispersed into a carrier material. The carrier material can then be dispersed into or coated on the cardboard to form an effective barrier or trap.
