Abstract

909,009. Couplings between relatively movable conducting parts. RADIO HEATERS Ltd. Dec. 8, 1960 [Dec. 8, 1959], No. 41726/59. Class 38 (1). A screen for preventing interference frequencies escaping from a high-frequency generating source comprises two members 1, 2 (Fig. 3) which together enclose the source, member 2 having a peripheral lip 3 which interleaves with peripheral lips 4, 5 on member 1, the members 1, 2 being connected electrically by spring clips 8, 9. In this arrangement (and in Figs. 1, 2, 4-6, not shown), the members 1, 2 comprise the lid and casing of a radio-frequency heater. In an alternative arrangement (Fig. 8) two radiofrequency ovens 21, 22 having peripheral lips 31-33 and 34-36 are connected by spring clips 7 clipped on an H-shaped member 25. In a further arrangement (Fig. 10) a radio-frequency oven 21, having a lipped edge 48, is joined to a rectangular duet 46 with a lipped edge 49 by the four sides (two of which, 50, 51, are shown) of a box-like duct, the four sides being mitred at their corners to support each other when in position.
