The rotor 11 is mounted on a shaft 10 supported in bearings 5, 9 in which it has radial play. The bearing 5 is bored out to receive a worm conveyer 21 and a breaker rotor 22 provided with helical grooves which decrease in depth toward the discharge end 24<a>. The cover 3 of the cylinder A is recessed to provide concentric rings of teeth 35 which engage with corresponding teeth 32 on a disc 30 loosely mounted on the shaft 10 and driven thereby through pegs 31 on the rotor. The liners which surround the rotor are in two parts and are water-jacketed, the bottom liner 12 being rendered immovable by a set-screw 18 whilst the upper liner is radially movable as the inlet and outlet pipes 16, 17 to the water-jackets are slidable in their glands 19. The disc 30 is pressed against the cover plate 3 by a spring 61 which is adjusted against the end of the shaft 10 by a screw 8. The teeth on the disc 30 and the corresponding teeth on the cover 3 are radial and are shown in Fig. 5. the direction of rotation being indicated by the arrow a. The teeth on the rotor 11 and liners 12, 13 are also of the shape shown in. Fig. 5. and are of helical form of large pitch. In a modification the rotor and shoes may be provided with grooves 77, Fig. 7, the material in one groove being conveyed to an adjoining grinding surface by means of holes 78; similar holes are also provided in the annular rings of teeth on the cover 3. The material enters at 23 and is conveyed by the screw 21 to the breaker rotor 22 from which it is discharged into the space 24<a> and is swept therefrom by a projection 22<a> into holes 24 at the centre of the disc 30. The material then passes through the disc mill and rotor and is discharged by arms 51 through the outlet 52. When a film of material forms between the lower liner 12 and rotor 11 the latter rises slightly due to the play in the bearings and carries the upper shoe with it so that the material is subjected to a pressure due to the weight of the rotor and upper liner.

Title: Antenna unit
IPC: H01Q3/12
Filed: 1955-07-25
Abstract: 772,120. Directive radio systems. STANDARD TELEPHONES & CABLES, Ltd. (International Telephone & Telegraph Corporation). July 25, 1955, No. 21440/55. Class 40(7) A rotating directive aerial system, capable of handling signals over a wide band-width but sensitive to energy of vertical polarization only, consists of a vertical fat dipole 1, a cylinder of insulating. material 10 co-axially mounted round it having vertically-extending, fairly.narrow, spaced conductive strips attached to or contained in the insulating material over a portion of its circumference to form a reflector, and means to rotate the cylinder. The dipole may be fed by a co-axial cable 2 extending up inside the lower dipole element and having its inner conductor 4 attached to the upper dipole element 5 and its outer conductor 6 attached to the lower element 7. The insulating cylinder 10 which may be of fibreglass is supported for rotation about the dipole by means of bearings 16 and 17; it may be driven by motor 18 through gearing 19. The whole aerial is enclosed in a protective housing 22, also of non-conductive material which does not affect the radiation pattern and this housing supports the top of the dipole and the bearing 16. The reflecting strips each have an electrical length of #/2 at the lower end of the frequency band to be received and may be wires or ribbons of conductive material or stripes of conductive paint. Because of the narrow width of the strips the reflector is not sensitive to horizontaly polarized energy. In systems for use at lower frequencies, where the physical length of the reflectors would be excessive if they were arranged linearly, zig-zag or greek fret configuration strips may be used (Figs. 3 and 4, not shown). The aerial system may be used in a direction finder by arranging for the motor 19 to drive an alternator 21 in synchronism with the aerial rotation. The outputs of the alternator are fed as reference signals to the stator windings 23 of a phase-meter 24. The rotor 25 of the meter is fed from the aerial through receiver and amplifier 26 and high-impedance transformer 27. The purpose of this highimpedance transformer is to prevent the phase meter acting as a motor whilst allowing it to indicate the azimuth of the received signal.
