Title: Machine for automatically perforating and "spiral" binding blocks of sheets, and possibly inserting the hooks for the preparation of calendars
Inventor: PESENTI PIGNA DANIELE
IPC: B42B5/12
Filed: 1983-06-01
Granted: 1987-06-25
Abstract: An automatic machine is described for perforating blocks of loose sheets, binding them from a continuous spiral, and possibly inserting the hook to form wall calendars, all the movements of mechanisms being centralised, there being provided the facility for obtaining perforations and thus bindings which are either continuous or in the form of portions which are separated in a manner which can be preset at choice. The feed of the sheets to be perforated and then to be bound is effected by means of chains provided with fixed brackets, with which there correspond mobile tabs which can withdraw into or project out of the conveying surface, their movement being coordinated with that of the chains and of the perforation mechanism. The feed of the spiral to the station in which the coupling takes place with the perforated sheets is effected by two independent brake- friction units, controlled separately by digital controls, which can be preset.

Title: Aqueous coating compositions and methods for preparing same
Inventor: CHU SHAW CHANG
IPC: C08G59/42
Filed: 1983-12-20
Granted: 1989-06-08
Abstract: Aqueous compositions suitable for sanitary can coatings comprise the neutralized water dispersible ionic polymer product of the reaction of an epoxy resin with an acid polymer, and a different resin which is not necessarily self-dispersible in water. The different resin is introduced either preformed at any stage or is prepared, in situ, in the presence of the epoxy resin esterified with acid polymer either before or after the ionic epoxy resin-acid polymer product is dispersed in water. The epoxy resin-acid polymer product acts as a polymeric surfactant capable of keeping even the normally non self-dispersible second polymer in stable dispersion in water.
