Abstract
1501930 Electric resistance heating LIEBELT PALMER & CO Ltd 20 Aug 1976 [11 July 1975] 29183/75 Heading H5H A helically coiled wire heating resistor 5 is wound upon an insulating corrugated former 3, enclosed within a mechanically protecting and electrically insulating body. The protecting body may be sheets of insulating material 2, 4 or an embedding mass. A rigid outer casing may be provided. Former 3 is corrugated, 7, for flexibility and notched 8 to locate the resistor. Former 3 and plates 2, 4 may be of mica, asbestos, asbestos compound or ceramic. The embedding material may be a ceramic or magnesium oxide. The casing, of stainless steel or mild steel or brass, may be formed as a bobbin and closed by an outer plate 12, or be open on the inner side during manufacture and closed by an inner plate. Leads 9, conduit 10 may be brazed on. The heater may be an incomplete annulus (Fig. 3, not shown) for ease of clamping around a member (e.g. an extrusion nozzle), or a complete annulus, as shown, or a plate.
