Abstract: The artificial heart valve consists of a ring (9) with a shut-off element (10) joined to it by a coupling (11) which allows the shut-off element to rotate between its open and closed positions. The coupling, located on the inner surface of the ring, is itself annular in shape and fits against the rings' surface. It can be made with an inward projection (13) and a recess on its inner surface (14), and has a shut-off element in two halves (12) which open and close together to control the passage of blood through the valve. Each of the shut-off element halves is slightly curved in shape and has curved cam surfaces on its side facing towards its matching half, ensuring the appropriate distance between the two halves when in the open position.

Abstract: The invention relates to a digital transmission system for the simultaneous transmission of a plurality of binary digital signals via separate conductor pairs. In addition to a threshold detector (SD) known per se, a noise value predictor (1) is used. Its sampling values are derived from the differential signal (ri) obtained from the Nyquist-equalised signal (ki-1) and the detected signal (vi). This considerably increases immunity to cross-talk interference.

Abstract: The invention relates to a heat exchanger comprising a heat exchanger grid having a multiplicity of oval tubes (3), and a baseplate attached to said grid by widening the tubes (3). The ratio of the diameters of the tubes (3) is 2.5 : 1 to 8 : 1 inside the heat exchanger grid, and 1.2 : 1 to 3 : 1 inside the perforations of the baseplate. A process for fixing such heat exchanger grids to a baseplate is also described. This process is characterised in that before being widened the tube ends are deformed from outside by applying pressure with the aid of a special pressure tool (15, 15a,b), with the result that their cross-sections are reduced parallel to the maximum diameter but increased, by contrast, parallel to the minimum diameter. <IMAGE>

Abstract: A method and apparatus for performing division is described which first comprises approximating the short reciprocal of the divisor. A reciprocal bias adjustment factor is added to the approximation and the correctly biased short reciprocal is multiplied by a predetermined number of the most significant bits of the dividend and the product is truncated to generate a first quotient digit value. The multiplication takes place in a multiplier array having a rectangular aspect ratio with the long side having a number of bits at least as large as the number of bits required for the divisor. The short side of the multiplier array has a number of bits slightly greater by several guard bits than the number of bits required for a single quotient digit value, which is also determined to be the number of bits in the short reciprocal. The quotient digit value is multiplied by the full divisor and the exact product is subtracted from the dividend to yield an exact partial remainder. The described steps are repeated to serially generate quotient digit values with exact partial remainders with the preceding partial remainder taking the place of the dividend. The quotient digit values are accumulated to yield a complete quotient. The complete quotient is decremented and the remainder recalculated if the final partial remainder is negative, yielding the full precision unique quotient and non-negative remainder pair.

Abstract: A floating point processor for performing arithmetic operations on floating point numbers includes a first arithmetic operation unit configured to operate on normalized numbers and a second arithmetic operation unit which includes a denormalizer for denormalizing normalized numbers and a normalizer for normalizing denormalized numbers. Each arithmetic operation unit has first and second inputs for receiving first and second operands, respectively, and an output for transmitting a result of the arithmetic operation. When an denormalized operand is presented as an input to the arithmetic operation unit configured to operate on normalized numbers, the denormalized input operand is redirected through the second arithmetic unit for normalization of the denormalized operand. The first arithmetic operation unit then performs its arithmetic operation using the normalized input operands. The result of the arithmetic operation is then analysed to determine whether it has a zero or negative exponent. If the result has a zero or negative exponent, the result is directed through the second arithmetic unit a second time so that the result is denormalized. The denormalized result is then output.

Temporally varying fields below the cutoff (F) can be detected by a synchronized stationary detector inputting to the processing equipment (10) so as to subtract such signals from the signals used to measure spatial field variations.
