Title: Method of counting glass balls supplied to a filament - extruding machine
Inventor: BRET JEAN-PIERRE
IPC: C03B37/085
Filed: 1969-08-23
Abstract: The glass balls supplied to a reservoir during the manufacture of glass filaments, roll in a guide track, and cause rotation of pref. a peripherally notched disc, by consecutive balls engaging adjacent notches.

Title: Manufacture of paint lined parts - has lining applied by vacuum and trimmed with a knife for vehicle interior finish
Inventor: EISSLER EWALD
IPC: B29C51/08
Filed: 1973-10-25
Abstract: The lined parts are made in one work cycle. The part to be covered is placed on a support die.
