[Class 40 (v)] A direction finding system comprises the usual frame and non-directional aerials R, H connected to the grid circuit of a valve E, and an additional non-directional aerial 2H coupled to the circuit at K and adapted to receive in phase-opposition substantially double the H.F. energy received by aerial H. The circuit of the aerial 2H is controlled by a switch S operated in a dot-dash rhythm for obtaining bearings. Fig. 2 shows the response curve of the system, the curve R+H showing the field of response of aerials R, H and curve (R+H)-2H that of the aerials R, H, 2H. This arrangement therefore produces a zero bearing which is at right angles to the plane of the frame aerial. The amplitude of the additional non-directive effect may be varied by the coupling K and the zero bearing may consequently be adjusted. This adjustment facilitates compensation for drift of a vehicle. Non-directional effects in the frame aerial may be utilized instead of separate aerials.

Abstract: 984,038. Laminates and laminating. D. KILLEN. Feb. 6, 1964 [March 8, 1963], No. 9287/63. Heading B5N. A web of material 1 having a thermoplastic surface is fed through a microwave resonator 6 where it becomes heated sufficiently to plasticize the thermoplastic surface, whereafter it is united to another web 3 by pressure. In a preferred embodiment a web 1 having a thermoplastic surface and a web 3 are passed together through a resonator cavity 6 with which is associated a microwave power unit 7 and a waveguide 8. The webs are then laminated together by passing them through the nip of a pair of press rolls 9. Alternatively, air jets may be used to press the webs together. The web 1 may be passed alone through the resonator and thereafter combined with a second material. The process may be used to join two textile webs together in which ease the thermoplastic surface is a thermoplastic adhesive applied for example by spraying as at 11, or one or both sides of a thermoplastic foam may be covered with a textile layer, the thermoplastic surface of the web itself being plasticized. The temperature to which the thermoplastic material is raised may be regulated by the provision of a substance of different di-electric coefficient e.g. iron filings on its surface.
