Title: Improvements in or relating to television transmission
IPC: H04N5/228
Filed: 1936-12-10
Abstract: 479,551. Television transmitters. RADIOAKT.-GES. D. S. LOEWE. Dec. 10, 1936, No. 33926. Convention date, Dec. 10, 1935. [Class 40 (iii)] The intervals between the completion of the illumination, by the object to be transmitted, of individual elements of a photo-electric plate 7 and the subsequent scanning of those elements by a cathode-ray or the like are substantially equal. The illumination is interrupted by a rotating diaphragm 4, which, together with the object, is sharply reproduced on the light-sensitive plate. The diaphragm is close to the plate or to the object, or a lens projects the object on the diaphragm and a further lens projects the diaphragm on the light-sensitive plate, Fig. 1 (not shown). The diaphragm has a plurality of long apertures 11, which extend parallel to the lines scanned by the ray and move perpendicularly to those lines in the same sense as the progression of the lines. The apertures uncover only one or a few lines at a time and move over the complete area in a time which is equal to that of a complete scanning. The duration of the illumination of an element is of the same order as the interval between the completion of its illumination and the scanning. When a film is .advanced intermittently, the scanning is interrupted for the duration of the advance of the film plus that of illumination of an individual element. According to a modification, the apertures are in a spiral, similarly to those in a scanning-disc, Fig. 6 (not shown). Each of the apertures uncovers only a fraction of one line to give a storage effect without harmful reaction between the individual photo-electric charges. The diaphragm may be constructed analogously to scanning discs for interlaced scanning, as described in Specification 465,184, to uncover the lines of elements in triple or other multiple interlaced sequence.

Title: Improvements in rotary engines, pumps and like rotary power plant
IPC: F04C2/344
Filed: 1960-10-07
Abstract: 923,657. Rotary power plant. S. BURGESS (K. Eickmann). Oct. 7, 1960, No. 34378/60. Class 110 (2). A rotary pump, compressor, or liquid, gas, steam or I.C. engine of the outwardly-sliding vane type, comprises vanes having axial extensions radially slidable in slots formed in plates adjacent the rotor sides and rotatable with the rotor and a chamber containing or receiving fluid under pressure disposed axially outwardly of a plate and closed by a cover rotating with the rotor, the cover or rotor parts being axially slidable to an extent limited by axial fastening means to provide a counterbalancing pressure chamber. As shown in Figs. 1 and 2, a rotor 1 eccentrically mounted in an adjustable casing ring 2 is flanked by slotted side-plates 3 enclosed by casing members 4, 5. The casing member 4 is formed on its outer face with an annular recess 9 sealingly closed by a complementary flange on a cover member 8. Bolts 11 secure the rotor, side-plates, casing and cover members together. The inlet and exhaust of the medium to and from the working chambers takes place through the rotor shaft (not shown) and channels 16 in the rotor 1 and a bush 14 on which the rotor is fixed. On low pressure machines in which friction can absorb a large proportion of the generated power the lower pressure in the recess 9 allows larger axial clearances between the rotor parts with consequent reduced friction. On high pressure machines in which friction losses are proportionately not so great, clearances are reduced, to reduce leakage of pressure fluid and increase machine efficiency. Disc springs 25, Fig. 3, may be fitted in a recess in a side-plate 22 to act in opposition to fluid pressure in a chamber 27. In this embodiment the rotor 21 is concentrically mounted and a close fit in its casing with a pair of diametrically disposed working chambers as shown in Fig. 4. In another embodiment, three rotors separated by side-plates and with further outer sideplates are mounted on a common shaft to rotate together. The axial length of each outer rotor equals half that of the middle rotor and the working chambers of the rotors are arranged to improve the balancing of the rotor parts. The eccentric casings may be either fixed or adjustable. If adjustable, that of the middle rotor is arranged to move in opposition to the casings of the outer rotors. Specification 744,446 is referred to.
