An omni-directional aerial 10, Fig. 4, comprises a hollow hemispherically shaped dielectric (e.g., plastics) material shell 11, three spirally wound ring shaped radiating elements 13, 14, 15 each placed around the inner wall of said shell, a cylindrical symmetrical star-shaped cross-section reflector 25 located within said shell, and a filter circuit, Fig. 7 and Fig. 8 (not shown), also located within said shell. The radiating elements are made from aluminium or other conductive wire, and are twisted into spirals along their lengths, as shown in Fig. 6. The elements 13, 15 are, respectively, larger and smaller in diameter than the element 14 and are fixed to the wall of the shell 11, respectively, nearer and further from the base thereof than the element 14. The reflector 25, Fig. 5, may be made from aluminium sheet and have four points. It is supported by cardboard bracing 26, which is shaped to fit closely against the inner wall of the shell 11 and to hold the reflector coaxially with the radiating elements. The filter circuit comprises a toroidal ferrite core 30, Fig. 7, having a double primary winding between terminals 71-74 and 71-75, respectively, and a secondary winding between terminals 71-73, and a capacitor 22 connected between terminals 72-73. A single tap on the element 15 is connected to the reflector 25 and to the terminal 71, and pairs of spaced apart taps on the elements 13, 14 are connected, respectively, to the terminals 71, 75 and 72, 74. A twin-wire feeder is also connected to the terminals 71, 73. After the components are positioned within the shell 11 it is filled with a polyurethane substance 31, and is closed with a plastics material base cover. In a typical aerial of this kind the element 13 is stated to be effective for the UHF and higher-frequency VHF television broadcast channels, whilst the elements 14, 15 act in combination to receive lower-frequency VHF channels, as well as FM broadcasts.

IPC: H03C1/24
Filed: 1922-02-15
Abstract: 175,635. Ges. f³r Drahtlose Telegraphie. Feb. 16, 1921, [Convention date]. Thermionic modulating systems.-In a wireless transmitter employing a thermionic valve with two grids, the anode feed current and the potential of the space-charge grid are influenced simultaneously by the speech current through separate circuits, and the space-charge grid may be kept at the same potential as the anode. The anode is shown as connected to a positive main, which may be 110 volts above the negative main and the filament F. The grid G is connected as shown to the oscillatory circuit O, for the purpose of generating oscillations. Modulation is effected by the variations of potential applied to the anode A by secondary S of a transformer, the primary P of which carries a current induced by the microphone M through the transformer T1, T2. To prevent the steady component of the current in the circuit P, T2, from magnetizing the covers of the transformers, compensating windings C, T3' are provided and the current therein is adjusted by means of a variable resistance W2. In order that the space-charge grid R may be always at the same potential as the anode A, it is connected to an adjustable point in a resistance W1 which carries the telephone current.

In the apparatus shown, the shoot C carries the distributor E and is detachably mounted on the body A of a motorvehicle, the inner end being level with the bottom of the vehicle. The feeder D, D<1> is also mounted on the detachable shoot C, and a hinged tail-hoard F rests on side members F<2> which are fixed on the shoot C and detachably connected to the body A. The size of the delivery opening is regulated by adjusting the tail-board by hand-levers H and notched segments H<1>. The feeder blades D' are adjustable radially and angularly on the shaft D and may be arranged to feed more material to one part of the distributor than another. Their shanks pass through the shaft and are secured by nuts on the ends. The distributor E is a cylindrical wire brush mounted above the curved part of the shoot C in adjustable spring-controlled bearings. It may be provided with a guard. The brush is driven from the feeder shaft bv chain gearing, and the feeder shaft from the road wheel Q by chain gearing and a clutch controlled by a lever U operated from the driver's seat. The distributor is driven in the same direction as the feeder and at a greater angular velocity. The gearing may be changed to vary the discharge. Deflecting-baffles V are detachably and adjustably mounted on the shoot C, so that the sand &c. may be spread over a wide strip. The shoot and distributor may be wider than the vehicle body. A rib W forms one side of a trough into which the sand &c. may be thrown by hand.
