Title: Packaging film and packaging of detergent compositions therewith
Inventor: ZIA HAQ
IPC: C08J7/043
Filed: 1982-11-10
Abstract: A packaging film comprises a base film of at least partially water-soluble plastics film, for example, polyvinyl alcohol, carrying on one side a protective layer of particulate inert plastics material, for example, polytetrafluoroethylene powder, having a high water repellency. The film is thus vulnerable to attack by aqueous media on one side and protected against such attack on the other. It may be used, with the protected side innermost, for unit packaging of detergent compositions, especially liquids containing bleach. In use in the washing machine, the unprotected surface is attacked by the wash liquor to release the contents; the protective layer prevents attack of the package by the contents during storage.

IPC: C03B7/10
Filed: 1998-04-17
Abstract: A parallel shear apparatus (10, 110) for sequentially shearing each of a plurality of streams of molten glass from a glass feeder into gobs for processing into glass containers by a glass forming machine. The apparatus has first and second opposed carriages (12, 14) which are reciprocable along parallel slides (18, 20) toward and away from one another, each of the carriages (12, 14) carrying one or more opposed knife elements (32, 34), corresponding to the number of streams of molten glass, and the opposed knife elements overlap at the innermost limits of their travel to perform the shearing action. Motion of the carriages (12, 14) is actuated by a unidirectionally acting servo motor (36), which imparts oscillating motion to a bell crank (22, 122) through a connecting rod (46, 146). The oscillating motion of the bell crank (122) imparts simultaneous, opposedc, rectilinear motion to the carriages through connecting rods (26, 30), which are pivotally attached to the servo motor at diametrically spaced apart locations. The servo motor is mounted on a pivoting bracket (40, 140) that is urged to its normal operating position by a pneumatic cylinder (144) and is spring biased (150) away from its normal operating position in the event of a stoppage. The pneumatic cylinder (144) is cushioned to minimize shock loads caused bys a sudden retraction of the servo motor mounting bracket (140) and is adjustably mounted relative to fixed structure of the shear apparatus. <IMAGE>
