Title: The production of iron from pelletized ores
IPC: C21B13/00
Filed: 1965-06-29
Abstract: Pelletized iron ores, particularly taconite ore beneficiated by magnetic separation, are reduced in a shaft furnace at 1300-1800 DEG F. with a gaseous atmosphere comprising CO and H2 generated by the incomplete combustion of fluid fuel e.g. CH4 with O2 and introduced into the mid-section of the furnace, the top gases of the furnace being withdrawn into a recirculatory system, in which they are cooled to abstract moisture and re-introduced into the shaft furnace below the mid-section or cooling section thereof whereby the reduced pellets are cooled.  Preferably a portion of CH4 is mixed with the cooled gases before re-entry into the furnace to combine with CO2 therein and produce CO and H2.  Refractory shapes may be mixed with the ore pellets before entry into the furnace and subsequently magnetically separated from the reduced pellets. The furnace preferably has a casing of upwardly tapering conical shape, the upper section being insulated.

Title: Device for counting particles in an aerosol
IPC: G01N15/14
Filed: 1973-06-08
Abstract: 1422188 Photo-electric condensation nuclei counters COMMISSARIAT A L'ENERGIE ATOMIQUE 8 June 1973 [21 June 1972] 27487/73 Heading G1A Aerosol particles are counted by passing the sample through a humidifier and then through a cooling system to condense liquid droplets on the particles which are then passed through a space monitored by an optical system using a photomultiplier to detect radiation scatter from the droplets. As shown, Fig. 2, the aerosol sample passes through a humidifier 1 having a chamber 15 the walls of which are lined with spongy material 14 fed with water by capillary action from an external reservoir (not shown). A low power heating element 10a may be used to assist in the saturation of the sample with water vapour. The sample then passes through a tapered conduit 26 which is cooled by a Peltier cooler 5 so that the water vapour condenses on the aerosol particles to increase their effective size. The sample is jetted into a chamber 30 through a small diameter nozzle 29, the jet passing through a defined observation volume illuminated by a light beam which is scattered by the water droplets surrounding the particles to a photo-multiplier which produces a pulse at the passage of each particle. The pulses may be applied to an amplitude selector before being counted. The sample is drawn through the apparatus by a pump (not shown) connected to the exhaust conduit 17. The optical system Fig. 3 (not shown) comprises an incandescent lamp (3), a lens (37) and a closely located diaphragm (39) the aperture of which is focused by a second lens 38 on to the observation volume. A similar arrangement with its axis at 135 degrees to the first directs the scattered radiation to the photo-multiplier (9). It is mentioned that the apparatus may also be used for counting large particles by switching off the Peltier cooler.

Title: A new or improved fibrous cushioning material
Inventor: HOOD JOHN SAMUEL
IPC: B65D81/03
Filed: 1953-10-07
Abstract: Moulded cushioning units for use in packing, bedding, or upholstery are made by spraying a batt of cellulosic fibres 3 in. - 24 in. long with a water soluble adhesive to render its outer surface coherent, spraying the coherent outer surface with a vulcanizable natural rubber latex, and finally pressing the fibrous mass to a definite shape whilst subjecting its latex-coated outer layer to curing conditions.  The fibres may be wood wool or shavings, sisal, hemp, esparto, reeds, straw or eel grass.  The adhesive may be starch that has been dextrinised by partial hydrolysis in presence of alkali, and may contain sodium fluoride or formaldehyde.  The latex sprayed on as the outer layer may contain paradichlorobenzene or paranitrophenol. The batt may be preliminarily shaped during setting of the aqueous adhesive, e.g., by passing the sprayed batt through forming rollers after which it may be pressed by a heated platen or may traverse a drying tunnel.  The finally formed latex-coated material may be passed through a heated tunnel, or the period of heating may be reduced by heating the compressed air supply to the spray nozzles.

Title: Improvements in and relating to alternating-current generators
IPC: H02P9/42
Filed: 1920-09-28
Abstract: 151,651. Ges. f³r drahtlose Telegraphie. Sept. 29,1919, [Convention date]. Alternating - current induction machines; rotary converters.-The frequency of the current supplied from an alternating - current generator is maintained constant by so exciting the inducing member with an alternating-current of variable frequency that the sum of this frequency and the frequency corresponding to the speed of the rotor remains constant. In the arrangement shown in Fig. 1, current of constant frequency is supplied to the slip-rings S2 of a frequency changer K, the commutator brushes of which are connected to the slip-rings S1 of the rotor of the generator G1. The frequency changer is coupled to the generator G1 either directly or through gearing. The current of constant frequency may be supplied from a valve or from a synchronous generator G2 driven at constant speed by a continuous current motor M2. The voltage of the continuous current generator G3 supplying current to the motor M2 is maintained constant by means of a Tirrill regulator. The generator G2 is connected to the frequency changer k through a transformer t and capacities c. In the application of the invention to the generation of high-frequency current for wireless telegraphy and telephony, the generator G1, Fig. 2, supplies current to a synchronous motor M4 driving a high-frequency generator G4. The generator G1 is driven by an asynchronous motor M1 controlled by a resistance W1. A synchronous motor M3 drives a continuous current generator G3 from which current is supplied to the continuous current motor M2 and to the rotors of the synchronous machines G2, M3. According to the Specification as open to inspection under Sect. 91 (3) (a) the resistances W1, W2 are preferably switched in automatically. Also, the asynchronous motor M1 may be controlled by connecting it in cascade with a second motor or converter. This subject-matter does not appear in the Specification as accepted.

Title: Methods of and apparatus for producing stereo pictures and  to stereo colour pictures produced thereby
IPC: G03B35/00
Filed: 1972-06-13
Abstract: 1397768 Producing stereo pictures VIDEO WEST Inc 13 June 1972 27631/72 Heading G2A In making a stereo picture, a composite image is formed having a single central sharply focused image, together with two laterally displaced images in complementary colours corresponding to objects in background and foreground planes relative to the main object plane. As shown, a suitable camera, which may be for still or cinÚ photography, has a lens which is of the double meniscus type, and has between the inner meniscus elements 20, 22 an aperture stop. Positioned approximately at the aperture stop is a filter 30 divided into right and left hand elements 32, 34. The filter elements pass complementary portions of the spectrum, of equal visual energy content; as shown, half-filter 32 transmits red light and halffilter 34 blue-green light. Figs. (not shown) 8, 9 and 10 show alternative arrangements of the two half-filters. Assuming three posts 50, 52, 54 in the object space 42, post 50 being in the plane of interest, while posts 52, 54 are respectively in the foreground and in the background, the post 50 produces a sharp and coalescent image 60 at the photo-sensitive surface. Posts 52 and 54 produce images 62 and 64, which have a slight lateral displacement or fringing of the red and blue-green images. If these images are viewed through a pair of filtering spectacles, Fig.4 (not shown) of which one lens is red transmissive and the other is bluegreen transmissive, the viewer is induced to converge his eyes so as to bring the fringed images into registry, which induces a 3-D effect since this corresponds to the type of convergence required in viewing a real object. The image picture is compatible in the sense that it may be viewed without the spectacles, as a twodimensional photograph since the images 62 and 64 are not distinct double images.

Title: Apparatus for the transference of floating containers
IPC: B63B27/16
Filed: 1970-06-10
Abstract: 1,270,757. Winches; lifting devices. FRIED. KRUPP G.m.b.H. 10 June, 1970 [11 June, 1969; 12 Nov., 1969; 19 March, 1970], No. 28190/70. Headings B8B and B8H. An apparatus for the transference of floatable containers between water subject to wave motion and a ship, comprises hoisting winches 7 on the ship for lifting and lowering via cables 9, a carrier frame 11 couplable to the top of a container, and a seaway following winch 8 associated with each winch 7 for constantly maintaining the cables taut. Each corner of the frame 11 incorporates one or two sheaves 10 around which one or a pair of cables 9 are looped between the ends thereof which are wound on a hoisting winch 7 and a seaway winch 8. The winch 7 carries out the normal lifting and lowering operations whereas the winch 8 is driven by a main motor 20 to wind up the cable 9 only when the container is lifted by a wave. The winch 8 is also acted upon by an auxiliary motor 26 through a threaded clutch/brake mechanism 22, 23, 24 which provided the motor 26 is braked at 27, and provided the cables 9 are loaded by the container, brakes the winch 8 in the unwinding direction. The clutch-brake mechanism is released upon the winch 8 being driven by the motor 20 to wind up the cable 9. If the brake 27 is released, the auxiliary motor 26 drives to cause release of the clutch-brake, whereby the cables 9 can pay out as the container moves into a wave trough. The container is guided and held in position for engagement with the carrier frame by longitudinal timbers and a transverse buoyant shell having electro-magnets for engagement with the container and supported from the ship by pivoted spring buffers and a hoist. Two of the hoist winches are driven from a common drive through differential gearing to effectively provide a three point suspension for the container. The container is locked at each corner to the frame 11 by bayonet pegs 12 which are rotatable for locking once a switch 15 on the frame is actuated through a lever 16 by the container. In the embodiment of Figs. 4, 5, 6 (not shown) a protrusion at each corner of the container is engageable in a housing in the frame and a ram operated key thereon engages an aperture in the protrusion. In a further embodiment Figs. 9, 10, 11 (not shown), a protrusion on the container is received in a housing at each corner of the frame and a pair of grippers lock the protrusions therein as a result of a ram actuated scissor action of the grippers.
