Title: Machine tool working time evaluation method - summing two time values to account for weight, quality and complexity of workpiece
Inventor: MAYERAS ROLAND
IPC: G06C3/00
Filed: 1976-03-17
Abstract: The machining time evaluating method uses the sum of two time periods.

Title: Securing resin coatings to steel vessel walls - using a porous metallic fabric or sheet as an interfacial key
IPC: B01J19/02
Filed: 1976-11-12
Abstract: The walls of steel vessels for contg. aggressive liqs. are protected by spot welding >=1 layer of metallic fabric to the walls and then impregnating the fabric with a protective coating such as a thermosetting resin, esp. linings covered with several successive coatings of polyester resin reinforced with glass fibres.
