Abstract: A modular sign comprises a magnetic backing sheet, a chassis for supporting the backing sheet to provide a stable platform, and one or more sign inserts which may be coated on one side with a ferrous material so that the inserts can be held magnetically on the backing sheet. The magnetic backing sheet may include alignment ribs for aligning the various sign inserts on the backing sheet or it may be in the form of a frame with a single sign insert registered within the frame. The chassis can be supported in a frame which is made up of extruded frame members which can be connected in the manner of a picture frame. The frame members may be made with various slots or channels to retain various parts of the sign and/or to assist in mounting the frame against a horizontal or vertical surface. A light transmitting protective sheet may cover the sign. Where non- ferrous sign inserts are used, the perimeter of the inner surface of the protective sheet may be coated with a magnetically attractive material to retain the sign insert within the frame of magnetic material.

Abstract: A lower pre-heat block assembly 9 for use with a metal scarfing apparatus 5 is disclosed. The lower pre-heat block assembly has a lower block 38 and an extension 39 engaged upon and in overlying relationship with a front face 46 of the lower block. A gas discharge outlet 56 is defined within the front face of the block. The extension may partially overlie the gas discharge outlet such that a gas discharge orifice 70 is defined in the front face of the block by the extension. The extension includes an upper face 58 which extends forwardly from the front face of the block, and is recessed with respect to an upper face 41 of the block. So constructed, when a sheet-like oxidizing gas flow 82 is passed over the upper faces of the block and the extension, respectively, and as a fuel gas 85 is emitted through the gas discharge outlet, the fuel gas is pneumatically compressed between the oxidizing gas flow and the upper face of the extension such that the fuel gas is substantially uniformly distributed along the longitudinal length of the lower pre-heat block assembly and forms a uniform sheet-like fuel gas flow (90) which underlies and adjoins the sheet-like oxidizing gas flow so as to prevent ambient air from aspirating into the oxidizing gas flow and thereby result in a smooth and uniformly scarfed surface on the metal workpiece.
