Abstract
Abstract The invention relates to a novel method of re-inforcing very thin and brittle plates, particularly steel plates, which have a hardness exceeding 400 Brinell. The object aimed at is obtained thereby that an armouring is anchored to the plate, on one side thereof, whereafter the armouring is covered with synthetic resin which is then cured.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
A METHOD OF MAKING RE-INFORCED THIN PLATES OF BRITTLE METAL COMPRISING THE STEPS OF: CASTING A THIN PLATE OF STEEL HAVING A HARDNESS IN EXCESS OF 400 BRINNEL AND HAVING RECESSES DISTRIBUTED ON A MAJOR SURFACE THEREOF FOR RECEIVING ANCHORS THEREIN, BONDING SPACED-APART ANCHORS IN SAID RECESSES AND DISPOSE UPSTANDING AND PROJECTING FROM SAID MAJOR SURFACE OF SAID PLATE, PLACING ON SAID MAJOR SURFACE OF SAID PLATE A LAYR OF NET ARMOURING WITH SAID ANCHORS EXTENDING INTO SAID NET ARMOURING, ANCHORING SAID NET ARMOURING WITH SAID ANCHORS DIFFUSING SYNTHETIC RESIN THROUGH SAID NET ARMOURING AROUND SAID ANCHORS AND IN CONTACT WITH SAID MAJOR SURFACE, AND CURING SAID SYNTHETIC RESIN TO INTIMATELY BOND SAID NET ARMOURING TO SAID MAJOR SURFACE OF SAID PLATE AND SAID ANCHORS FOR REINFORCING SAID STEEL PLATE.
Claim 2
Independent Claim
130 words
