Patent GB-1437368-A (GB)
Title: Production of prismatic graphite fuel elements
IPC: G21C3/28
Filed: 1973-07-06
Abstract: 1437368 Compression moulding graphite fuel elements NUKEM GmbH 6 July 1973 [6 July 1972] 32305/73 Heading B5A In a process for the production of prismatic graphite fuel elements, by means of a compression moulding operation, the material to be moulded is compressed in a cavity of polygonal cross-section by simultaneously moving the side walls 1 of the cavity towards the longitudinal axis of the cavity, openings to serve as cooling bores and/or for accommodating fuel being formed by heatable cores 10, the heatable cores being freely movable in the molding material during compression. Movement inwards of the side walls 1 is by rotation of ring 7 to which each wall is connected by a lever 6 (shown in Fig. 1). The direction of movement of the walls is determined by guides 2 on each wall which slide in grooves 3 on the mould base plate 4. As shown in Fig. 2, the mould cores 10 are moved into the cavity, during filling, by lifting of an assembly plate 12, on which the cores are supported by a centring plate 15. A further centring plate 11 helps to position the cores within the moulding material 9. The right hand side of Fig. 2 shows the position of the cores, during moulding, when they are held in position solely by the moulding material 9 and are able to follow lateral movements of the material 9 during compression. The moulding material may be a mixture of petroleum coke and a binder such as phenol formaldehyde resin, in which case the finished element is graphitized after moulding. Alternatively, graphite pressing powder may be used. In an example, a fuel element having hexagonal bores for fuel and cylindrical cooling bores is produced from a mixture of graphite pressing powder and binder, and separately moulded fuel columns (produced in a mould similar to that described, but without the cover) are introduced into the fuel bores. The resulting assembly is then finished by compression and heating to carbonize the binder. It is also stated that mixture coated fuel particles and binder may be used to produce the elements, the fuel being in this case uniformly distributed throughout the block.

Abstract: 137,289. Pomeon et Fils, A. Dec. 27, 1918, [Convention date]. Addition to 137,068. Cupping and the like.-In a machine as described in the parent Specification, the stamping- plunger is adapted to form the beadings in grooved dies, or the plunger itself may produce internal beadings or grooves instead of external ones. As shown in Fig. 1, the plunger comprises a main member m, the lower portion of which is formed with a groove m<1> into which the paper or cardboard is forced when the blank is cupped in a die a. The lower part of the plunger is formed with an annular piston b within which is arranged a piston c formed with an enlarged bottom portion c<1> which presses the bottom of the cupped box &c. against a fixed support. Before this support is reached, the pistons b, c are maintained in the position shown in Fig. 1 by a spring r which acts on a disk d between which and inclined surlaces f, i on the pistons is arranged a set of balls c. The outward movements of the pistons c, b, are limited respectively by the head j of a screw which passes through the disk d and screws into the piston c, and by screws h which pass through the plunger m and engage the tops of recesses b<11> in the piston b. After the piston c has engaged the fixed support, the continued descent of the plunger causes in the first place the piston b to close on the piston c and the amount B, Fig. 1, of this relative movement is arranged to give sufficient material to form the bottom beading 1 of the box in the die groove g, the pistons and plungers then being in the position shown in Fig. 3. The action is completed by the plunger m closing on piston b as shown in Fig. 4, to a depth A, Fig. 1, sufficient to form the beading 2, as shown in Fig. 4, which shows the final position of the plunger. The die is formed in two parts which are moved apart for ejection of the box. In a modification, the groove g' for forming an external beading is replaced by co-acting grooves at the meeting edges of the piston b and plunger m, and in this case the beading or groove is internal. The apparatus may be arranged for the formation of more than two sets of parallel beadings, as described above.

IPC: D01C1/02
Filed: 1936-12-05
Abstract: Natural fibres in loose state but free from hard bark, husk, or skin, or textiles made of such fibres are subjected to the action of caustic alkali of a concentration between 2 and 6 DEG  Tw., without application of heat or pressure, in order to reduce the natural hardness of the fibres, render the materials more flexible and soft, render non-cellulosic constituents soluble, and give the materials greater affinity for dyestuffs.  The fibres may be of vegetable or animal origin, but treatments of fibres of duda (Hibiscus Cannabinus) and of sisal or similar hard fibres of the Agave family are excluded. When the treatment is carried out in hot climates, the treatment bath may be cooled by means of a cooling coil.  The treatment results in the extraction of waxes, gums, resinous bodies, and pectic substances from vegetable fibres such as cotton, flax, hemp and jute, and of resins, keratin, wool fat, and vegetable matter from animal fibres. After the alkali treatment the materials may be pressed, washed, and pressed.  In the case of flax and jute fibres, the pressure treatment begins the longitudinal splitting of the fibres into finer fibres. The splitting process may be continued after the material has been dried, by passing it through a crimping machine.  Examples describe the treatment of jute roots, decorticated flax straw, and unbleached cotton cloth.  Specifications 147,080, [Class 120 (i)], 383,627, [Group IX], and 458,310 are referred to.
