Title: Electrical apparatus for producing a "saw-tooth" potential
IPC: H03K4/12
Filed: 1932-05-19
Abstract: 394,476. Converting. SCHLESINGER, K., 39, Friedrichstrasse, Friedrichshagen, Berlin. May 19, 1932, No. 14241. Convention date, May 20, 1931. [Class 38 (ii).] Apparatus for producing a "saw-tooth" potential for use, for example, in producing the time deflection in cathode-ray oscillographs and for scanning in television apparatus employing Braun tubes comprises a condenser 8 which is charged through a thermionic valve 1 having a cathode 2, an anode 9, and a grid 6 connected to a high positive potential so as to accelerate the electrons before reaching the anode. The anode current is thereby rendered practically independent of variations of anode potential. The condenser 8 is charged so that its potential rises at a uniform rate until it reaches the ignition potential of a glow discharge tube 12, whereupon the condenser is discharged. The grid 6 may have a positive potential of about 1000 volts, a resistance 7 of about a megohm being included in the circuit to limit the grid current to about 1 milliampere. The cathode 2 may be produced by the barium vapour process and may be heated by a filament 3. The hightension supply may be a battery 5 or mains supply apparatus. A synchronizing potential may be applied at 13. The frequency of the charging and discharging cycle may be controlled bv regulating the potential applied to an additional grid electrode between the cathode 2 and grid 6, for example by a variable tapping on a potentiometer resistance connected across a battery. This control may be automatic in accordance, for example, on the intensity of the image element to be transmitted in a television process, as shown in Fig. 3. The fluorescent spot on the screen 19 of a cathode-ray tube 20 is focused by a lens 18 on a film 17, which is capable of being advanced line by line at right-angles to the plane of the drawing. Behind the film 17 is a matte screen 25 and a light-responsive cell 26, which is connected through an amplifier 27 to control the potential of the grid 14 of the thermionic valve 1 through which the condenser 8 is charged. The frequency may be reduced by applying an alternating potential to the grid 14, the bias being chosen so that the ignition voltage of the tube 12 is reached only after a certain number of oscillations.

Abstract: 602,234. Thermionic power converters. M-O VALVE CO., Ltd., and RAMSAY, H. T. Nov. 5, 1941, No. 14259. [Class 39 (i)] Thermionic gas - filled rectifiers having a solid thermionic cathode 1 separated from the anode 2 by a labyrinth passage, has a baffle electrode 11 disposed on the cathode side of a control electrode 5 ; during the blocking period, the negative potential of the control electrode 5 is greater than that of the baffle electrode so that the deionisation period may be lessened and incidental sputtering of the electrode 5 prevented from contaminating the cathode. For this purpose the bias battery 7 is connected to the baffle electrode 11 through a relatively high resistance 12 and to the control electrode through a choke 8 of relatively low resistance. The starting impulse may be applied to both electrodes by a pulse generator 9. In the arrangement shown, the cathode 1 is an oxidecoated ribbon directly heated ; the cathode space is surrounded by a metal cylinder 3 with restricted end 3<1> which supports by brackets and insulators 11<1> two cup-shaped metal members 4 carrying the control electrode 5. The baffle electrode 11 is also mounted on the cylindrical member 3, 3' by insulators 11<1>. The Provisional Specification also describes the arrangement shown in Fig. 1 in which 3 is a canister surrounding and connected to the cathode 1 ; auxiliary electrode is made up of the canister 4 round the anode 2 and a plate 5 covering a tube 6 projecting into the canister 3. The parts 4, 5, 6 are connected together and a maintained negative to the cathode by a battery 7 and choke 8. The discharge is started by a pulse from a generator 9 through a resistance 10 to auxiliary electrode.

Title: Mapping camera
IPC: G03B41/02
Filed: 1941-11-07
Abstract: 567,391. Cameras for aerial photography. CHICAGO AERIAL SURVEY CO. Nov. 7, 1941, No. 14366. Convention date, Oct. 26, 1940. [Class 98 (i)] A camera for producing a continuous photograph of the ground flown over by an aircraft, in which the film is continuously moved during exposure, comprises a finder having a continuously moving member driven in synchronism with the film and bearing spaced transverse lines which are visible through the finder screen, means for conjointly controlling the speed of this member and of the film, and longitudinal lines on the screen extending in the direction of movement of the member. The speed control is adjusted to maintain the speed of movement of the finder image equal to that of the moving member, and the camera is angularly adjusted so that the image does not move laterally in relation to the longitudinal lines on the finder screen. In the camera shown, film is constantly fed during exposure from a spool 29 to a take-up spool 33 by an apertured feed-roll 32, the film being held to the roll by the action of suction means connected to the hollow interior of the roll. The take-up roll is rotated from the feed roll through a slipping spring belt drive 65. The film passes over an exposure slot formed between two plates 26, 27, the former of which is movable by means of a wedge plate 31 to vary the width of the slot. The feed roll is rotated through helical gearing and a clutch 63 from a motor 47, the speed of which is adjustable by means of a control button 76. A finder lens projects an image on a ground glass plate 40 behind which moves a transparent endless indicator strip 38 driven by the motor, on which are uniformly-spaced transverse lines. By controlling the speed of the motor, the cross lines may be made to maintain coincidence with the moving finder image, when by closing the clutch 63 the film will be driven synchronously with the strip and at the speed at which the main image crosses the exposure slot. Lines 42 on the plate 40 extending longitudinally, i.e. in the direction of movement of the strip 38, indicate lateral movement of the image, which is corrected by angular adjustment of the camera. The camera is carried in a gimbal mounting so that the optical axis may be inclined to correct for aircraft movements, and may also be rotated about a vertical axis so that the direction of movement of the film and indicator strip may be rendered parallel to the movement of the aircraft as modified by drift. A film footage indicator operated by a pivoted arm engaging the outer turn of the supply roll is provided.

Title: Improvements relating to the burning of cement
Inventor: SZINGER EUGEN
IPC: C04B7/44
Filed: 1952-06-10
Abstract: 728,836. Making cement. AMALGAMATED LIMESTONE CORPORATION, 'Ltd. June 10, 1953 [June 10, 1952], No. 14631/52. Class 22. A granulated mixture of raw cement material and solid fuel is formed into beds on grates in separate containers in which the burning cycles are staggered, the air flows upwards through each bed, and the containers are continuously or intermittently fed with additional mixtures of raw material and fuel as the burning progresses so that the bed depth increases as the burning progresses from the bottom upwards and the combustion zone during the greater part of the burning is always covered by a thin layer of fresh raw material and fuel, the burned beds of clinker being successively discharged so that cement is produced continuously. Ignition of the containers in position 1 is aided by downdraught. Addition of the charge is related to the burning so that by the time the container is full the burning is nearly complete. A layer of pre-burned clinker is interposed between the bed grate and the lowest charge, and the proportion of fuel in the charge decreases from the bottom to the top of each container. Small sized pre-burned clinker may be included in the charge. An empty container is charged in position 21 and pushed along a track 77 by hydraulic means 66 to position. 1 where the charge is ignited by burner 35, combustion air being drawn down by a blower 36. Hydraulic mechanism 65 pushes the container into each of the positions 2 to 19, each position being occupied by containers in progressive stages of burning or cooling. Subsequent charges are added from a conveyer 55, scrapers 56 and shoots 57. Burning is completed in position 13 though no more material is added after position 10. Cold air is supplied to positions 11 to 13 but the main cooling takes place between positions 14 to 19, cold air being passed therethougli and being heated. This heated air passes through pipe 53 into air chambers 23, 24, 25 and through the charges in the containers in positions 2 to 10, by means of increasingly powerful blowers 37, 38, 39. A cold air mixing valve 54 in the pipe 53 regulates the temperature of the preheated air. The containers are discharged in position 20 and the contents sieved, the :coarse material being crushed. Fine material passes to sieve 70, the coarser fraction forming the grate covering clinker the finer fraction being taken by a conveyer 75 to be mixed into fresh raw material. Some or all of the heated air passing through the pipe 53 may.be used for drying cement slurry or generating steam, and the hot gases passing to atmosphere through a pipe 52 may also be employed similarly, and in this latter event the last layer charged to the containers is fuel only.

Abstract: 1379126 Manufacture of lactams CHEMIEBAU DR A ZIEREN GmbH & CO KG 29 March 1972 [18 June 1971] 14710/72 Heading C2C Lactams are manufactured from cycloalkanone-oximes (optionally one made by reaction of hydroxylamine sulphate solution with a cycloalkanone and neutralization of the liberated H 2 SO 4  with NH 3  to form (NH 4 ) 2 SO 4 ), by rearrangement of the oxime with H 2 SO 4  or oleum, neutralization of the resulting mixture with NH 3  and separation of the lactam from the (NH 4 ) 2 SO 4  formed, wherein at least part of the latter is heated to 240 to 460 C. to split off NH 3  (with formation of NH 4 HSO 4 ), the NH 3  split off is used for the neutralization of the rearrangement mixture and/or of the H 2 SO 4  liberated during the oximation, the bisulphate formed is burnt at 850 to 1250 C. to produce a gas containing SO 2  and at least part of this gas is converted to H 2 SO 4  or oleum which is recycled to the rearrangement stage. The SO 2 -containing gas may also be used in part for the manufacture of hydroxylamine sulphate. The bisulphate is preferably burnt with a fuel containing sulphur and/or carbon (e.g. heavy oil, natural gas, H 2 S or sulphur itself) and in a combustion chamber at 950 to 1150 C. such that an oxygen concentration of 1 to 8% by volume is maintained in the gas issuing therefrom. It is preferred to burn an ammonium bisulphate melt containing 20-40 mole per cent of (NH 4 ) 2 SO 4 . The example describes the preparation of #-caprolactam from cyclohexanone and an aqueous solution of hydroxylamine sulphate. Other lactams for whose preparation the process is considered applicable are capryl- and lauryllactams and caprolactam whose precursor, cyclohexanone-oxime, has been manufactured photochemically from cyclohexane and nitrosyl chloride.

Title: Disposal of radioactive wastes from nuclear reactors
IPC: G21F9/16
Filed: 1963-04-16
Abstract: 972, 661. Processing radio-active waste. UNITED STATES ATOMIC ENERGY COMMISSION. April 16, 1963 [May 14, 1962], No. 14811/63. Heading G6R. Aqueous radio-active waste,particularly by waste in slurry or solution form is rendered insoluble and suitable for storage by heating it with sulphur in two stages, the first stage being at a temperature sufficient to dehydrate the waste and drive off volatile components and decomposition products, e.g. 130-160C., and the second stage being at a temperature, e.g. at least 350C., at which the radioactive material is calcined and rendered insoluble. The time of heating in the second stage is preferably about 5 hours. When the radio-active waste contains a preponderance of aluminium the temperature of the second stage is preferably about 400C., and when a preponderance of stainless steel, e.g. Fe, Ni, and Cr, the second stage temperature is preferably 440C. The Figure shows an apparatus suitable for the process of the invention. Vessels 1, 2 and 3 are equipped with heating coils 4,10 and 19; and agitators 5, 13a and 20. Vessels 1 and 2 are used for the process and vessel 3 serves as a safety precaution. Radio-active waste preferably in a slurry or similar thickened form enters through pipe 6, and sulphur through line 7. Coil 4 raises the temperature to 130-160C. and agitator 5 brings the waste to the surface of charge 28 and helps to drive off the gases through line 9, whilst a portion of the charge is transferred via line 8 to vessel 2 where the coil 10 raises the temperature to 350 to 444C. to calcine the waste and render it insoluble. Agitator 13a raises the treated waste to the surface and assists in driving off gases through line 13. The treated waste is taken off through line 11 to waste disposal means shown schematically at 12. The gases through lines 9 and 13 pass to scrubber 14 where on passing upwards through packing 17 they meet water from sprinkler 16 and the solution 29 so formed passes via pipe 18 to vessel 3 for a further precautionary sulphur treatment at a temperature of 130-160C. maintained by heater 19. Off-gases through pipe 25 are scrubbed in 21, the solution 31 formed being passed via line 26 into the ground 27. The atmospheres in vessels 1 and 2 are preferably inert, e.g. nitrogen, and about 1% wt. of sulphur containing rubber-like polymer, e.g. "Thio Kol" (Registered Trade Mark) A, may be added to the sulphur to improve the cracking resistance of specimens cast from the sulphur melt. The addition of 0. 77% wt. of iodine decreases the maximum viscosity of the sulphur and the presence of Fe, Cr and Ni compounds is said to improve the resistance to leaching and to harden, strengthen, and solidify the final sulphur matrix.
