Title: Digital computers
IPC: G06F17/14

Abstract: 1355390 Digital computers; Fourier transforme INTERNATIONAL STANDARD ELECTRIC CORP 23 Dec 1971 [29 Dec 1970] 59931/71 Heading G4A A digital computer is arranged to compute an approximation of the Fourier transform of a complex function z(t), which computer receives a sequence of m simultaneously available sample pairs from the function z(t) having known occurrence times ti, and the amplitude of which approximation represents the frequency spectrum of the sample sequence, the Fourier transform for the frequency fh being: and means being provided to compute the transform at four specified values only of the sine and cosine terms. The Fourier transform of a signal z(t), the amplitude and phase of which varies with time, dt = the z(t) frequency spectrum. The speed of this calculation is increased by approximating the sine and cosine components of the exponential term e-2#jft by the four values +1, ¢, - 1 and - ¢ (Fig. 1 and Figs. 2 and 3 (not shown)). A memory holds 2m binary words characterizing the real and imaginary parts of m samples of the analysed signal. The words are produced by a sampler and encoder (Fig. 5, not shown) which receives the real and imaginary components of the signal z(t). A second memory store 2m (w+1) two bit binary words characterizing the multiplier coefficients where (w+1) is the number of transform points to be computed, though this memory can be replaced by a computer circuit (Fig. 10, not shown) which computes the coefficients from the m values of the initial phase stored in a first auxiliary memory and from the m values of the phase increments stored in a second auxiliary memory. The second memory is read to produce 2m words. In Fig. 4 the real and imaginary components of four samples at times t1 to t4 are known. Registers Rx1-Rx4 hold the x components Ry1-Ry4 hold the y components, RC1-RC4 hold the cosine approximations and RS1-RS4 hold the sine approximations. These registers are connected to multipliers M1-M16 (Fig. 7, not shown) which multiply appropriate pairs and then sum the products using adders A1-A15. In another embodiment (Fig. 8, not shown) a series rather than a parallel computation is used. Separate devices may calculate the real and imaginary components and read only and ferrite core memories are mentioned. The computations may be used for a coherent Doppler radar system.

Title: Purification of spent sulphuric acid
IPC: C01B17/90
Filed: 1970-12-18
Abstract: 1284249 Purifying sulphuric acid STAUFFER CHEMICAL CO 18 Dec 1970 [9 Jan 1970] 60189/70 Heading C1A Chlorine, organic impurities and turbidity are removed from sulphuric acid which has been used in a chlorine drying process by contacting the acid with activated carbon and separating the activated carbon from the sulphuric acid. After use the carbon may be renewed by heating at above 500‹ F. in the presence of inert materials such as air, nitrogen, steam, carbon dioxide and methane. The sulphuric acid may be contacted with the carbon in a batch or continuous process. In the continuous process it is preferred that the most highly contaminated acid be contacted with the most highly contaminated activated carbon, e.g. by flowing the sulphuric acid downwardly over a bed of the activated carbon.

Abstract: A floor panel which is laid on a supporting construction to provide a base on which a secondary floor covering such as a textile-based carpet or plastics tiles is laid includes an upper sheet steel plate formed from two thin sheet steel plates (26, 28) bonded by a layer of adhesive (30) sandwiched therebetween. The composite plate is stuck onto knobs (20) which extend from a base plate of thermally insulating material and heating pipes (22) extend between the knobs (20) and are looped beneath the plates (26, 28). A layer of adhesive applied to the underside of the lower sheet steel plate (28) forms an array of parallel ridges on the underside thereof. In order to produce an interlocking between adjoining panels, the upper plate (28) is staggered at least along one edge and preferably two edges in relation to the lower plate (26) in each panel so as to produce an overhang along two edges and a rebate along the other two edges of each panel. By appropriately positioning adjoining panels so the overhang along an adjoining edge of one panel will overlie the rebate of the adjoining panel edge and a layer of adhesive will serve to bond the overlapping panel edges together. The adhesive is preferably a two- part adhesive and has sound- deadening characteristics and/or additives. <IMAGE>
