Title: Improvements in or relating to radio direction finders
IPC: G01S3/12
Filed: 1945-11-02
Abstract: 606,139. Radio direction-finders. STANDARD TELEPHONES & CABLES, Ltd. Nov. 2, 1945, No. 29216. Convention date, Dec. 11, 1942. [Class 40 (vii)] In a wide-band radio direction-finder comprising a directional aerial system (e.g. two spaced aerials coupled together in phase opposition or a loop aerial) and an omnidirectional sense aerial, one of the aerial systems is coupled to the receiver over two paths of different lengths, one of which contains a transposition, the mean length of the paths being equal to the length of the path from the other of the aerial systems to the receiver, and, in the preferred case when it is the sense aerial that is coupled over the two paths to the receiver, the difference in length being equal to the spacing between the aerials or between opposite sides of the loop. The first of these conditions ensures that the signal from the sense aerial suffers a 90 degrees phase shift to bring it into phase with the signal from the directional system and the second ensures that the relative amplitudes of signals from the directional and sense aerials are independent of frequency. In the embodiment of Fig. 1, a directional system comprising aerials D1, D2 is coupled to a receiver 13 over lines L1, L2. A sense aerial S1 is coupled to the receiver over two lines L3, L4, one of which, L3, includes a transposition. The units 14, 15, 16 from which the aerial voltages are supplied to the lines are decoupling units of the kind described in Specification 591,867. In the embodiment of Fig. 4 (not shown), a crossed Adcock aerial system with a goniometer is used. Fig. 5 shows the invention applied to a loop aerial system, part of the two paths from the sense aerial being common, the conditions as to the total length of any one path from the aerial to the receiver still being obeyed.

A method of producing subterranean piles by impregnation of soil in situ with a consolidating medium, e.g., a suspension of cement, sand cement, clay in water or chemicals causing a gel reaction, or bituminous emulsions, comprises forming a hole 8 of smaller diameter than the pile and enlarging it progressively by erosion from the bottom of the hole by the upward progression of a rotating single stream of grouting medium from the jet 6a, the grouting consolidating medium being added to the hole in two successive upward passages of the jet. The pump 1 supplies liquid, e.g., water, to the rotating jet 6a from the pit 13 and during the first drilling excess liquid together with entrained soil particles pass through the pipe 9 and channel 10 to the settling tank 11 and liquid passes further over the weir 12 to the pit 13. When the drill has reached the required depth at which it is required to start consolidating the soil, grout is fed to the pit 13 from the tanks 15, the pump pressure is increased and the drill reversed up the hole to enlarge it and erode particles to form a suspension in the top it is again reversed to a downwards direction, with the eroding power of the jet made less by reducing the jet velocity or jet size, to be raised again after it has reached the bottom of the hole. The particles may be separated by a mechanical separator or hydraulic classifier to be rejected or returned directly to the hole while the remaining liquid is recirculated through the jet.
