Abstract: An internal combustion engine has first and second cylinders (12, 14), the first cylinder (12) having a larger swept volume than the second cylinder (14) and the second cylinder being formed in the crown of the first cylinder. First and second pistons (16, 18) are reciprocable respectively in the first and second cylinders (12, 14), the second piston (18) being formed as a protrusion on the crown of the first piston (16). The first cylinder has an air inlet (25) and an exhaust outlet (27) whilst a first fuel source (34) provides fuel to the second cylinder (14). The second piston has a crown (35) which is spaced from and connected to the crown (36) of the first piston and which has an edge (37) which is relatively thin in the axial direction compared to the spacing of the first piston crown from the second piston crown. This defines a combustion space (20) between the piston crowns and a side wall (14a) of the second cylinder (14) when the pistons are substantially at the inner dead centre position. The combustion space (20) communicates with both cylinders (12,14) during part of the expansion stroke. Inhibiting means is also provided for inhibiting ingression prior to the pistons (16,18) arriving at or adjacent the inner dead centre position. This can take the form of a gap (128) between the second piston crown (35) and the second cylinder side wall (14a) with a peripheral groove (39) in the second cylinder wall at its upper end to enable the fuel/air mixture in the second cylinder (14) above the crown (35) to bypass the piston crown when the latter is at its inner dead centre position and enter the combustion space (20).

Abstract: In order to display a part of a physical structure on a screen, an intermediate, so-called pointers memory is created. Addresses of memory words of the pointers memory correspond to the co-ordinates of the pixels of a visual display screen, or, equivalently, to the corresponding addresses of the memory words of a memory of images. The data contents loaded into the word memories of the pointer memory represent the addresses of a so-called original memory representing, via its collection of memory words, the structure to be studied. It is shown that by using this pointers memory it is possible, for each pixel of the structure, to rapidly know the co-ordinates of the site where it should appear on the screen and thus the addresses of the corresponding memory words in the pointers memory by using addresses calculated in advance for this pointers memory. It is shown that this use of addresses calculated in advance avoids having to carry out, on one hand, multiplication and, on the other hand repeated accesses to the original memory. In this way, the processing is very rapid. <IMAGE>

<IMAGE>
 of the scalar product is reduced into partial sums fi of binary variables xki, which take one of the values of the fixed components ak according to the values of the xki according to m possibilities. A dedicated logical coding (1) makes it possible, on the basis of the variables xki, to generate for each bit of rank j of fi, a plurality of elementary partial sums, at the bit level, fij according to 2<m> possibilities by variation of the binary values akj of the bits of rank j. A bidimensional interconnection matrix (2) makes a single value of the elementary partial sums fij, whose set defines the corresponding partial sum fi, correspond to each bit of rank j akj.
