Abstract: 1360502 Colour television AGFA-GEVAERT AG 19 July 1971 [18 July 1970] 33851/71 Heading H4F A film 4 is scanned by a flying-spot scanner 1, the transmitted beam being drawn out by lens 5 into a line 6 which is projected on to red, green and blue strip filters 7, 8 and 9, the red and blue strip filters, 7, 9 carrying gratings of opaque lines which cause the transmitted light to have different carrier frequencies which can be separated from the output of a photomultiplier 10 by frequency filters. The different carrier frequencies are in a non-integral ratio with each other. The three strip filters 78 and 9 may be replaced by nine strip filters in a recurring sequence (Fig. 3, not shown), the length of the scanning line 6 then being equal to three strip filter widths. Alternatively lens 5 may be replaced by beam-splitting means/prisms or semisilvered mirrors) to produce three beams, one for each strip filter 7, 8, 9 (Fig. 4, not shown). Two photomultipliers may be used, one (13, Fig. 5, not shown) for green light and one (14) for red and blue light. In a further embodiment the carrier frequencies are imparted to the light before it passes through the film 4 in which case the scanner screen la has three portions covered with red, green and blue filters, the red and blue filters having line gratings printed on them (Fig. 6, not shown). The three portions may be line-scanned simultaneously, the resulting beams being combined and passed to film 4, the film movement producing the frame scan, or a single cathode-beam may be alternated between the three filter areas at a high frequency so as to produce three line scans almost simultaneously. The carrier frequencies may be imparted by electronic means rather than gratings, and the light output of scanner 1 may be non-white, while still containing a proportion of each of the primary colours.

Abstract: 166,080. Jackson, W. J. Mellersh-, (Hawaiian Pineapple Co., Ltd.). Nov. 30, 1920. Cutting and slicing pineapples.-Relates to a machine for removing the edible substance from opened and flattened pineapple husks which are obtained when the ends of the fruit have been cut off and the usual cylinder of edible substance has been removed. The husks are placed, exterior surface downward, on a conveyer 9 and are moved from the drum 3 toward the drum 6, upon which drums the conveyer 9, which is provided with gripping-spikes 10, is carried. The larger drum 3 is mounted on a shaft 4 which may be extended to drive a battery of machines. The edible substance is removed by a vertically adjustable obliquely-arranged knife 11 carried by posts 14, 18 secured to the main framework, the posts having slots 13, 17 for the reception of the terminal pieces 12, 16, which are provided with transverse openings and a pin 15 and a tightening screw and nut 19 respectively. The husks are retained in a flattened condition by a plurality of vertically adjustable plates 23 tied by bolts 26 and carried in a frame 24, which is provided with a lid 27 and is secured to the framework by bolts 31, the for. ward ends of the plates 23 being bevelled to facilitate the introduction of the husks.

The edible substance passes over the knife 11 to a shoot 20 which registers with the back of the knife and is pivoted at the lower end at 20 and vertically adjustable at the other end to permit of registration with the knife in all positions. The husks pass under the knife and over the drum 6 to a conveyer 33 and thence to a suitable receptacle.

Filed: 1975-10-28
Abstract: 1519774 Wind and water turbines R PATTEN 28 Oct 1975 [31 July 1974] 33888/74 Heading FIT An apparatus for generating power from naturally available energy comprises an upright wall structure 10 and peripherally extending inlet valves 17 arranged to admit fluid flowing from any direction into inlet chambers 15, fluid from the latter driving rotary devices 14 coupled to power transmitter means 21. As shown, structure 10 is a multi-sided or cylindrical tower framework having at its base inwardly opening non-return flap valves 17 which admit wind to chamber 15 to drive horizontally disposed turbine rotor 14. Air from the latter flows into outlet chamber 16 and then exhausts through outwardly opening non-return flap valves 18, or alternatively through flap valves in partition wall 19 into the inlet chamber of a further turbine stage 12. The latter also has wind inlet and outlet valves 17, 18. Several further stages 13 are provided. All the turbines 14 are on a common shaft 20 driving an electric generator 21 or pump. The latter may form part of a pumpedstorage electrical generating plant. Convection currents may assist rotation of turbines 14. The driving fluid may be water rather than wind.

Title: Improvements in or relating to propulsive rotors
IPC: B64C27/04
Filed: 1953-12-07
Abstract: 770,873. Aircraft; propelling ships. COOKE, W. D. Sept. 22, 1954 [Dec. 7, 1953 ; Jan.13, 1954], Nos. 33950/53 and 970/54. Classes 4 and 114. A propulsive rotor for aeroplanes, helicopters or ships includes a radial duct system rotatable as a unit about an axis and arranged to take in fluid at an inner circumference, accelerate it radially, and discharge it at an outer circumference in a direction having a substantial component parallel to the axis, the fluid stream being expanded in a portion of the duct system, the cross sectional area of which does not decrease and which terminates at the outer circumference, thus converting kinetic energy to pressure energy. In Fig. 2, the duct system comprises an upper annulus 1 having a circular inner periphery 3, and a lower annulus 2 having a hexagonal inner periphery 3a. Cables 11 connect the duct system with a rotatable ring 12 mounted on the fuselage 15. Radial vanes 7 and 8 divide the annular duct into sectors. The hexagonal inner periphery 3a of the annulus 2 is provided with six rollers 22 on which triangular blinds are rolled, the apex of each being connected by cable to a pulley 26, so that when the pulley is rotated, each blind is drawn to the centre of the annulus 2, closing the orifice therein so that the rotor may act as a parachute. In Fig. 4, the rotor comprises upper and lower annuli 66, 67. When functioning as a helicopter rotor, a circular disc 65 is lowered by rod 64, to leave an aperture in the upper annulus 66 through which air is drawn, to be discharged through openings 70. The openings are coverable by plates 72, connected through rack and pinion mechanism to the plate 65, so that all apertures in the rotor are together sealed or unsealed. When sealed, the rotor acts as a fixed wing for forward flight. Air bled from an engine 31 is led through valves 60, 61 and pipes 53, 54 to distribution channels 51, 47 in a member 48 rotating with the rotor. Air is led from channel 51 to jet orifices at the rotor circumference directed to rotate the rotor in one sense. Air is led from channel 47 to further orifices to rotate the rotor in the opposite sense. Valve 78 is fully opened when the rotor is driven for helicoptic flight, but is partly open when the rotor is rotatable in either sense through valves 60, 61 for lateral control in forward fixed wing flight. When used as a ship's propeller, the device is located forward as a tractor. Specifications 770,874, 770,875 and U.S.A. Specification 1,964,179 are referred to.
