IPC: E04G11/48
Filed: 1967-11-07
Abstract: 1,250,875. Building-appliances &c. RAPID METAL DEVELOPMENTS Ltd. 23 Oct., 1968 [7 Nov., 1967; 26 Feb., 1968], Nos. 50567/67 and 9135/68. Heading E1S. In shuttering for concrete slabs comprising vertical props with movable heads, beams mounted between the props and panels mounted between the beams so that the panels the tops of the beams and the heads define the shuttering surface, panel supporting elements are slidably mounted on the beams and can be moved from a locked position where the face of the supported panels is level with the top of the beams to an inoperative position where the panels are below the cast slab and can be removed. As shown, the beams have square section vertical members 19 on which the panel supporting elements 20 can slide vertically. The locking means for the elements 20 comprises a slab 22 with a keyhole shaped slot which engages grooves on bars 19 and the panel supporting element 20 provides a rectangular platform with projections at the four comers which engage the sides of the panels 10. At each end of the beams is located a projection 24 (not shown) with a recess in its underside and this is clamped to the head 13 of a prop 12 by a screw. The props may be joined by interconnecting members 31 attached to lugs 30 on the props. In use, a concrete slab is cast over the assembly of props, beams and panels, the tops of which form a level surface. When the concrete has nearly set, locking elements 22 are released, the panel supporting element 20 are lowered and the panels removed by freeing them from elements 20 and lowering them under the beams. When the concrete is almost fully set the beams may be removed leaving the formed slab supported on the props and prop heads.

Abstract: 1,257,487. Moderator structures. CREUSOTLOIRE. 18 July, 1969 [6 May, 1969], No. 36345/69. Heading G6C. A reactor core comprises a plurality of prismatic graphite columns, e.g. 11, 12 and 13, so juxtaposed that each surface of a column not situated at the periphery of the core is in register with an opposite surface of an adjacent column, separated by an interval or gap 18 to allow for its free expansion due to temperature fluctuations during operation. The hexagonal columns of the embodiment described contain control rod and fuel ducts (not shown) and a central duct 111, 121 or 131 in which a handling appliance for the column can engage. The columns are supported at their upper ends by closure elements 2 each comprising a base 21 of hexagonal section and three vertical supports 22 each with an external plane surface 23 parallel to a corresponding surface of the column. Three rocking levers 24 are suspended by pivots between the supports 22, each lever having a plane external surface 26 which bears against the external surface 23 of the opposite support 22 of an adjacent column. Each lever 24 has an inner thickened portion so that the centre of gravity of the lever is offset with respect to its suspension axis. The lever thus naturally tends to bear against the support of an adjacent column and it thus forms a ,shield against gamma and neutron radiation in the gap 18. The central duct 111, 121 or 131 of each-column is closed by a plug 28 having a widened top part bearing on the inner edges 241 of the three levers 24 of the column. If the gap 18 between the columns is reduced as a result of expansion of the columns, the levers pivot slightly and maintain a constant application force, the plug 28 being simply lifted slightly. The pivoting of a lever may be externally controlled by operating a pivot control arm 29 which forms an.extension of each lever above its suspension axis. In,this way it is possible to tilt the levers in order to isolate a column from its surrounding columns so that it can be removed. The columns may be keyed together, in which case (Fig. 5, not shown) each lever has on its outer surface a lug which, when the lever is applied against the support of an adjacent column, engages in -a notch formed in the support. In this way, each column is perfectly held by the keying system irrespective of the force of application of the levers against the supports, while maintaining freedom for expansion.

The method comprises stacking a plurality of sheets of uniform thickness on one of the press platens, the material being substantially unsusceptible to compression when being cut by a knife; placing on the uppermost sheet a cutting tool comprising a block 1 in which a plurality of knives 3 are regularly located and individually slidable; operating the press to cause the knives to cut through some of the sheets; discarding the sheet or sheets not cut by the knives and every sheet which every knife has cut through; removing part or parts of the material of each remaining sheet in regions which have been cut by the knives; and using the remaining parts to form a profiled pad in which the remaining parts occupy their original positions prior to the cutting step. As described the knives 3 are cylindrical and slidable in holes 2 in blocks 1 which cover over 80% of the area of the platen. The sheets used may be cellulose sheets or films.  The profiled pad may be formed by placing the sheet parts between two outer sheets of paper or metal and securing them in place by adhesive.
