Abstract

1,139,542. Datum level indication in earthworking or tunnelling operations. WILLIAM F. REES Ltd. and J. B. GARNETT. 16 Feb., 1967 [21 Feb., 1966], No. 7533/67. Heading E1F. A datum level indication in earth-working or tunnelling operations is provided by a narrow laser beam, which may be projected along a datum level, or be caused to sweep to and fro over a datum plane, or may be projected along a datum level after reflection when emitted from a laser source not at the datum level. Machines, e.g. dozers or tunnelling machines, may be maintained manually or automatically on a datum level defined by the beam, which co-operates with sensors provided on the machines.
