Filed: 1951-11-14
Abstract: 720,479. Eye-protectors. SVENSKA AEROPLAN AKTIEBOLAGET. Nov. 14, 1961 [Nov. 16, 1950; June 15, 1951], No. 26639/51. Class 97 (1). [Also in Groups XI, XXXII and XXXVIII] In a vehicle lighting system (see Group XI) the field of view of the driver is opened and closed simultaneously with the intermittent energization of the headlights by a Venetian blind type of screen 18 adjustably pivoted to the windscreen and comprising a plurality of parallel thin metal bands 38 occupying the whole or a portion only of a rectangular frame and adapted to be oscillated about their longitudinal axes:' The ends of the bands are narrower than the middle parts and are clamped in the C- sectioned side members 34 of the frame between distance-pieces 44, Fig. 4, each of which has an offset part with a stud 46 which passes through a hole in the end of a band 38 and enters a recess 48 in the adjacent distance - piece. Rubber fillets are disposed between the distance-pieces and the frame. The bands are held under tension by nuts 52 on the ends of the two horizontal tubular members 30, 32 of the frame. The bands are oscillated by an electro-dynamic device 98 secured to the upper horizontal frame member 30 and comprising a fixed magnet and a movable coil energized by electric current pulses. The movable coil is connected by a link and lever to a shaft 70 rotatably mounted in rubber-lined bearings in members 72 secured to the frame. The oscillating movement of the shaft 70 is transmitted to the metal bands 38 by two pairs of vertical ribs 62 which are connected at their upper ends to pins in rubber-lined bearings in arms 64 on the ends of the shaft 70 and at their lower ends to pins in rubber-lined bearings in arms 76 rotatably mounted on spindles 82 secured to the lower horizontal frame member 32. Each rib has a longitudinal rubber fillet with transverse parallel grooves in which the edges of the bands are engaged so that as one rib of a pair moves longitudinally and the other rib of the same pair moves in the opposite sense, the middle portions of the bands are rocked about their longitudinal axes. The frequency of operation of the screen is high enough to provide continuous non-flickering vision.

Title: Television scanning means
IPC: H04N3/38
Filed: 1936-10-05
Abstract: 488,419. Television. RADIOAKT.- GES. D. S. LOEWE. Oct. 5, 1936, No. 26957. Convention date, Oct. 4, 1935. [Class 40 (iii)] In a transmitter a rotating ring of lenses 3, co-operates with an illuminated aperture 12. A reduced real image 21 of the aperture is formed by a lens 13. The second dimension of scanning is produced by using a spiral of lenses or by an even vertical movement of a film 4. For interlaced scanning an odd number of lenses is provided in the disc, which rotates an odd number of revolutions to each single image. The disc is driven by a four-pole synchronous motor which is fed through an odd frequency multiplier from alternating-current mains of the same frequency as that of the repetition of the images. When the lenses are on a cylindrical surface, the illuminated aperture is perpendicularly opposite the surface of the cylinder and symmetrical with the scanned area of the film, which is advanced parallel to the surface of the cylinder, Fig. 3 (not shown). The lenses are in a spiral of one turn, and as many illuminated points as there are revolutions of the disc per image are so uncovered successively by a synchronously rotating diaphragm that the spots projected by the disc scan adjoining zones in succession, Fig. 4 (not shown). According to a modification, the radial luminous line 21 is intersected by a transparent spiral 23 in a disc 22, which rotates once per image period. The point of intersection moves in an oscillation of saw-tooth wave form. Each scanning-lens also projects an image of a second illuminated aperture 32 through a covering plate 30 to illuminate a second photo-electric cell 27 beyond the edge of the film for a short space of time to produce a synchronizing signal. This cell and the cell 26 for producing the picture signals are illuminated alternately and the light for one is prevented from affecting the other. The two cells are connected in opposite senses to the first stage of a common amplifier, and the intensity of the synchronizing signals is adjusted by regulating the light, Fig. 1 (not shown). Specifications 464,483, 465,184, and 466,571 are referred to. According to the Specification as open. to inspection under Sect. 91, when the lenses are in a spiral, the illuminated aperture is so positioned that all the scanning-spots from the lenses describe equal arcs, and the plane of the film scanned by the spots is at an acute angle to the plane of the disc, Fig. 3 (Cancelled) (not shown). This subject-matter does not appear in the Specification as accepted.
