Title: Improvements relating to indicating devices for radio receivers
IPC: H03J1/10
Filed: 1938-08-25
Abstract: 518,425. Indicating-apparatus. TELEFUNKEN GES. FR DRAHTLOSE TELEGRAPHIE. Aug. 25, 1938, No. 24996. Convention date, Aug. 25, 1937. [Class 106 (iv)] [Also in Groups XXXVI and XVIII]  The tuning indicator of a radio receiver comprises a flexible element  formed with a bight and carrying the indicator between the bight and a remote roller over which the element passes, the end of the bight being arranged to be displaced when the indicator has  to be moved, so that the distance moved by the indicator is greater than that moved by the end of the bight. Fig. 1 shows an indicator Z carried by a flexible cable L secured at one end to a spring controlled drum H for tensioning the cable, fixed at its other end E and formed into a bight passing around a guide pulley S and looped round a roller R secured eccentrically to the guide pulley S. The pulley S is driven by the shaft W, for example of a variable condenser, so that the distance moved by the indicator Z is twice the linear displacement of the rollers R. To avoid friction due to the slip between the cable and the guide pulley S, the latter may be constructed as shown in Fig. 3, in which the roller R is carried on a crank S preferably formed as a pulley P secured to the spindle W and the portions of the. cable on the sides of the bights are led around freely mounted pulleys S<SP>1</SP>, S<SP>2</SP>. The pulley S<SP>1</SP>, of course, remains stationary and the moving pulley S<SP>2</SP> which rotates at twice the speed of crank S may be coupled at Q to a fine adjustment control. The pulley P may be used to couple spindle W to a control knob or driving shaft. Alternatively, the cable L may be wound around the tuning knob spindle to drive shaft W. In a modification the cable is fixed at each end E, H, Fig. 3a, and formed with bights at each end which pass over the guides S<SP>1</SP>, S<SP>2</SP>, in different directions. Thus the cable L passes from the anchorage E clockwise over guide S' around roller R, then anti-clockwise over guide S<SP>2</SP>, over fixed pulleys M, K anti-clockwise around guide S<SP>2</SP> over roller R and then clockwise over S' to the tensioning spring F anchored at H. In another modification, Fig 2 (not shown); a construction similar to that of Fig. 3 is shown in which the cable tensioning means is dispensed with. The basic principle of the invention may be used to obtain speed ratios greater than two between the speed of the indicator and the roller R. Fig.. 4a (not shown), for example, shows an arrangement where the ratio is three. The cable may be formed entirely of steel, or of steel from one end up to the pointer, the remainder being formed of cord, any increase in length of which is taken up by the spring drum H, Fig. 1, or by the spring F, Fig. 3a.

Title: Improvements in and relating to windmills
IPC: F03D3/04
Filed: 1923-10-08
Abstract: 217,485. Zucker, G. F. Oct. 8, 1923. Current motors; regulating.-A windmill has a rotatable vertical shaft 20 which supports horizontal planes 24, 26, 32 between which are blades 40, 42, 44 hinged radially to the planes 26, 26, 24 respectively. Angular stops prevent the blades from swinging beyond the vertical position when they are in position for the wind to operate, but during the feathering action they swing to the planes and may be latched in position. The latches are held on by springs and hold the blades out of action unless released by means of the handles 86, 94, 98. Each blade has an arm with an adjustable counterweight 60 to enable it to deal with any wind pressure. Safety supplemental (doors 62 are hinged at openings in the blades and are held closed by adjustable compression springs 66 which permit the doors to open when the pressure on the blades becomes excessive. In a modification the blades axe replaced by frames with a grid structure 116, Figs. 8 and 9 the frames being secured by hinges 115 to the planes. The front face of the grid is flat while the rear face forms part of a cylindrical surface and is provided with hinged doors 124, 126, 128, 130, having adjustable restraining springs 132. The wind thus enters a series of passages before reaching the doors. To collect wind for the active side and to deflect it from the feathering side, the apparatus shown in Fig. 11 is employed. It swings on a part 150 and has vanes 152 which cause it to take up a position with the open end 154 pointing towards the wind. The open end has an extension 158 which protects the feathering side of the windmill from the wind; the end contains three air passages, one 142 directs air on to the blade 42 the second 144 directs air on to the blade 44, and the third 140 directs air on to the Made 40.

Title: Process for the production of gas containing hydrogen and deuterium
IPC: C01B4/00
Filed: 1973-05-29
Abstract: 1432429 Hydrogen of increased deuterium content; heavy water FRIEDRICH UHDE GmbH 29 May 1973 [29 May 1972] 25517/73 Heading C1A The deuterium content of the hydrogen stream produced by reacting steam with coal or hydrocarbons followed by conventional purification of the resulting H 2 /CO mixture is improved by subjecting all water which is condensed from the gas stream during the course of production to a direct-isotope exchange process using either the steam fed to the process as the partner in the exchange system or the gas mixture produced by the process at any point ahead of the carbon monoxide conversion svstem. The reaction may be carried out in the presence of oxygen or a free oxygen containing gas and preferably the condensate is subject to isotope exchange with both the steam fed to the process, and the gas/water vapour mix produced in the process. Deuterium enriched water obtained in the exchange may be mixed with the condensate or the steam fed to the process, and the gas produced during the reaction may be exchanged with this water at a stage when the gas originating from the process contains at least 0À6 kg./m.<SP>3</SP> of water vapour. The isotope exchange is preferably conducted on the counter current principle. In an embodiment illustrated in Fig. 1, preheated hydrocarbons, e.g. light naphtha, are fed through line 1 to cracking furnace 2. The required steam is first introduced into line 3 where it passes into an exchange column 4 where it is enriched with deuterium. It is then mixed via line 5 with the hydrocarbon feedstock. The gas leaving furnace 2 is further cracked in furnace 6 to which air is admitted via line 7. The gas leaving 2 is cooled via heat exchanger 8 before being sent to coconversion unit 9. The gas leaving 9 is cooled in heat exchangers 10, the condensate being retained in separators 11 from which it is recycled to the exchange column. The cooled gas passes on to further purification steps and finally to be utilized in an enrichment plant.

Title: Web winding means
IPC: G03B17/30
Filed: 1971-04-19
Abstract: 1343615 Winding film webs EASTMAN KODAK CO 19 April 1971 [6 April 1970] 25922/71 Heading G2A In a method of winding a web such as a strip of photographic film on to a core 11, the core is tilted relative to an adjacent wall by the drag of the web on it as it is rotated to take up the web. As shown, the core is a generally cylindrical member having a hollow lower portion. It is housed in the take-up compartment 2 of a film cartridge Fig.1 (not shown), and integral with the bottom wall 9 of this compartment is a conical post 15. This is received in the hollow part of the core, and is just long enough to lift the bottom of the core free of wall 9 so that it can float. The top of the core has a gear 7 which can be engaged by a corresponding gear in the camera, and so driven. Initially the longitudinal axis of the core coincides with the axis L-L of the compartment 2. The leading end of the film strip F is attached to the core by a paster tab. As soon as a drive is applied to the core by the film advance mechanism of the camera, the drag of the film on the core causes it to tilt, so that its axis assumes the position L<SP>1</SP>-L<SP>1</SP>. Thus the edges E of the film strip F engage against the top and bottom walls 8, 9 of compartment 2. As the convolutions of the film strip build up on core 11, the edges E which engage the walls move continuously further away from the core, and the film winds on to the core in an accurate and orderly manner. In a modified arrangement Fig. 7 (not shown) the film has only one edge E bearing against the bottom wall only. Figs. 3 and 4 (not shown) are of further ways in which the core may be mounted. Instead of the drive from the camera being transmitted by the gear arrangement shown, it may be transmitted by a disc carrying a number of lugs Fig. 5 (not shown) which engage in recesses in the end of the core.
