Title: Combine harvesters
IPC: A01F12/18
Filed: 1970-07-29
Abstract: 1318071 Combine harvester CLAYSON NV 29 July 1970 [30 July 1969] 36696/70 Heading A1F In a combine harvester, part of the strawwalker mechanism is replaced by an additional separating device to effect further threshing and grain separation. The cut crop is conveyed to the threshing cylinder 4 and cooperating concave 5, and from there it is fed to a rotary beater 22, having equiangularly spaced plates 37, which guides the crop over a grate 21. The plates 37 beat the crop as it passes over the grate 21 to effect a certain amount of grain separation, and in addition the nature of the slats 31-34 is such that a threshing effect is achieved. From there the crop passes to a tined cylinder 24 co-operating with a two-part concave 23. The tines 67, reinforced by gussets 70, are inclined rearwardly with respect to the direction of rotation of the cylinder 24, and are fitted in staggered, equiangularly-spaced rows. The first part of the concave 23 has longitudinally extending slats 39-45', mounted edge-on to the working surface, interconnected by curved transverse slats 46, and thus both threshing and grain separation are effected. The rear part of the concave 23 comprises longitudinally extending U-shape girders 52-55 having their surfaces inclined as shown, and thus grain separation only is effected. The grate 21 and both parts of the concave 23 are preferably adjustable, with respect to the beater 22 and the cylinder 24. The beater 22 and grate 21 could be replaced by a crop transporter, and the concave 23 could be made in one unit, taking the form of either the front or rear part. Alternatively, a sieve or similar device could be used to form the concave, or a portion of the concave in combination with the described front or rear parts. Further separation could be effected by means of an air flow below the concave 23 onto the material coming from the additional separating device. The whole additional separation unit could be an accessory, where it is fitted when the nature of the crop or the desired capacity requires the additional mechanism.

Title: Improvements in or relating to rotary duplicating machines
IPC: B41L11/00
Filed: 1959-11-05
Abstract: 898,123. Printing machines. RITZERFELD, W., and RITZERFELD, G. Nov. 5, 1959 [Dec. 10, 1958], No. 37564/59. Class 100(2) Tripping-arrangements; rotary machines. A rotary duplicating machine comprises a printing drum carrying a lithographic master sheet, a first counter-pressure roller of approximately the same diameter as the drum and having means fcr fixing thereto the leading edge of a copy sheet, said roller co-operating with the drum for printing the entire master sheet on a copy sheet, and a second counter-pressure roller which can be temporarily, rendered operative for printing a predetermined line or section of the master sheet on a further copy sheet. For printing the whole text from a lithographic master sheet 2, Figs. 1 and 3, secured to a printing drum 1, a copy sheet 21 is fed from a stack 23 to a counter-pressure roller 13 carrying a rubber blanket 14 and geared to the drum, grippers 20 for the sheet being actuated by a stationary cam 27, and sheet being delivered to a container 28. For printing selected lines of text, a copy sheet is fed between the drum and a second counter-impression roller 29, which is carried on levers 31 pivoted at 32, and moved against the drum at selected times by electromagnets 36. The roller 29 is geared to the drum, the gear teeth engaging to rotate the roller, even when the latter is moved away from the drum as far as permitted by' a stop 39. A sheet 51 is placed on a table 52 having a cut-out 68 for the roller 29 to pass through, and rests against an abutment 53. On pressing a lever 48, a switch 54 is opened to de-energize a magnet 55, raise the abutment 53 and close a sheet passage 58. At the same time, the lever 48 releases a pawl 45 pivoted on a contact arm 44 freely mounted on a shaft 43 to which is secured a disc 42, the pawl engaging a notch in the disc and rotating the arm 44, a contact 63 on which sweeps over a series of contacts K1-K19, each contact in series with a key T1 to T5 and so on. When the contact 63 engages a contact K whose key T is closed, a circuit is completed for a small current to an electrode control device 62, and a larger current from a rectifier 64 passes to the magnets 36. The contact 63 then engages a rail 65 and the roller 29 is again lowered to eject the sheet 52 into a container 66.

Title: Nuclear fuel element and process of making the same
IPC: G21C21/02
Filed: 1960-11-03
Abstract: 952, 090. Nuclear fuel elements. CARBORUNDUM CO. Nov. 3,1960 [Nov. 30, 1959], No. 37854/60. Drawings to Specification. Heading G6C. A fuel element for a nuclear reactor, for example, a reactor of the pebble-bed type, comprises a core consisting of a dispersion of graphite and nuclear fuel surrounded by a cladding, substantially impervious to fission products, of silicon carbide. The element may be made by shaping under pressure in a spherical mould a mixture of graphite, uranium carbide and phenolic resin, followed by heating in an oven to cure the resin. A slurry is then prepared from phenolic resin, ethyl alcohol, silicon carbide, graphite and gum tragacanth and applied to the core by dipping or spraying, followed by heating to cure the resin. The coated shape is placed in a crucible along with a small amount of silicon and fired in a vacuum furnace whereupon the silicon reacts with the carbon of the coating and the additional carbon formed in the coating upon carbonisation of the resin. By this means a high density, substantially impervious silicon carbide cladding is obtained. Zirconium carbide or titanium carbide may be used instead of silicon carbide for the cladding material (or mixtures of the three carbides may be used), which carbides may also be incorporated in the core. Graphite is the preferred moderator material but beryllium, beryllium oxide, beryllium carbide and mixtures of graphite and beryllium carbide may also be used. Where there is a possibility of the fuel reacting with the cladding material at the operating temperature of the element, the cladding is made of an inner layer of a refractory material inert to the fuel, such as graphite, and an outer layer of refractory carbide. A small amount of burnable poison, such as boron carbide, may be incorporated in the element. The fuel, instead of being dispersed throughout the core, may be in the form of a granule or pellet embedded in the core. Suitable fuels include, in addition to uranium carbide, metallic uranium, uranium oxide, uranium silicide and uranium-beryllium alloys or compounds, which materials may be mixed with fertile materials such as thorium carbide.
