IPC: G02B27/01
Filed: 1966-05-07
Abstract: 1,190,552. Cathode-ray tube displays. ELLIOTT BROS. (LONDON) Ltd. 26 April, 1967 [7 May, 1966], No. 20310/66. Heading H4T. [Also in Division G2] " Head-up " display apparatus comprises a pair of cathode-ray tubes each connected to a respective circuit and arranged to provide a composite display to an observer. The tubes 11 may be mounted as shown in Figs. 1 and 2 or reflectors may be provided to deflect the light from the tube screens through an angle of 90 degrees as shown in Fig. 3 in respect of the reflector 17 for one of the tubes. Other angles of deflection such as 75 degrees (Fig. 4, not shown) may be employed. An overall reduction in the size of the apparatus results since by giving the lenses 15 a diameter of about 5 cm. a display having a width in azimuth (when projected on to the window of an aircraft cockpit) equal to that of a 10 cm. diameter lens is produced and by moving the apparatus as a whole, in the case of the arrangement of Figs. 1 and 2 or by moving the reflectors in the case of the arrangement of Fig. 3 (or Fig. 4, not shown) the dimension in the vertical direction may be increased. The two tubes may be provided with complementary colour phosphors and by producing the more important information to be displayed on both tubes and the less important partly on one tube and partly on the other so that the former information is displayed in the complementary colour sum and the latter partly in one and partly in the other colour, the more important information continues to be displayed in the event of failure of one of the tubes. When the two tubes produce the same colour, however, failure of either tube is detected by the cessation of light from the tube falling on a photo-transistor or photo-cell 30 the output of which is arranged to actuate a visual or audible alarm signal. The outputs of the cells 30 are fed via notch filters which pass the 50 c.p.s. repetition frequency of the display and thereby prevents operation by extraneous light entering via the lens systems. Total failure of the display due to failure of one of the E.H.T. supplies may be prevented by employing separate E.H.T. supplies for each tube as shown in Fig. 5 or by the interconnection of both E.H.T. sources via the diode arrangement of Fig. 6 which operates to cause one of the sources to supply both tubes if the voltage of the other drops below that of the former source.

IPC: H01Q13/20
Filed: 1970-04-28
Abstract: 1294024 Aerials EMI Ltd 19 April 1971 20460/70 Heading H4A An aerial arrangement is constructed by printed circuit technique, in which a metallic pattern is formed adhering to an insulating substrate, and comprises one or more arrays of aerial elements. An associated strip conductor is spaced from each array, and energy is fed to or from each element by mutual coupling, not involving any physical connection. As described, a dielectric board 1, originally coated on both faces with copper, has one face etched to form the pattern shown, the other face 2 being left untreated for use as a ground plane. The pattern comprises six strip conductors 3 to 8, each terminating at one end in a single strip conductor 9. A co-axial feed cable is connected to the end 11 of the conductor 9. The other ends of the conductors 3 to 8 are formed with orthogonal portions as shown and are terminated in lossy loads, such as films of lossy rubber. Each conductor 3 to 8 is associated with six dipole aerial elements such as the one shown at 10. The degree of coupling between the elements and the strip conductors is dependent upon the proximities of the elements to the conductors, and upon the impedances of the. elements. Control of the degree of coupling may also be achieved by varythe width of a strip conductor, the elements being positioned at equal or varying distances therefrom (Figs. 2, 3, not shown). Elements may be arranged co-linearly, with the strip meandering to vary the coupling (Fig. 4, not shown). In other arrangements elements are disposed alternately on either side of a strip conductor (Figs. 5, 6, not shown). Two simultaneous beams may be obtained with a single signal input if two arrays of similar aerial elements are arranged on each side of a conductor strip, if the element-to-element spacing of one array is different from the other (Fig. 7, not shown). In a somewhat similar arrangement, dual-frequency operation is achieved by having the elements of one array larger than those of the other (Fig. 8, not shown). Elements may be specially shaped to influence the aerial bandwidth (Figs. 9, 10, not shown).
