Title: Continuous discrete fourier transform method and apparatus
IPC: G06F17/14
Filed: 1973-02-21
Abstract: 1408073 Computing Fourier transforms SANDERS ASSOCIATES Inc 21 Feb 1973 [23 Feb 1972] 8585/73 Heading G4A The Fourier coefficient F (k#) is calculated for any sequence of N samples of the input signal f(ZT). This is updated by adding to it the product of the reference value and the difference between the new sample and the sample which occurred N samples earlier in time. The process is repeated for each sample. The f(ZT) samples are delayed for an interval NT in shift register 10, where N is the number of samples in the integration interval of the discrete Fourier transform of any sequence f(nT) of the f(ZT) samples, where Z # n # Z+N-1. The difference between these and the new sample is calculated in adder/aubtractor 12 to produce a sequence of difference values and these are multipled in unit 13 by a sequence of complex reference values R(k#ZT) for at least one value of k to produce a series of products. The products are accumulated to provide an updated Fourier coefficient value for each value of z. This technique is stated to increase the number of points that can be calculated (Figs. 2 and 3, not shown). In another embodiment (Fig. 5, not shown) separate networks are provided for the real and imaginary parts. This correlates an unknown signal with a known reference signal over a fixed period of time and can be employed for signal filtering, correlations, convolution computations, spectral analysis etc. in communications, seismology, sonar, radar etc.

Abstract: 781,750. Water-tube steam boilers; regulating steam temperature. BABCOCK & WILCOX, Ltd. March 21, 1956 '[March 25, 1955], No. 8863/56. Classes 123(2) and 123(3) A water-tube boiler comprises an upright, steam generating tube lined setting which is divided into two parts by a partition formed of other generating tubes 22, the parts including radiation chambers 24, 26 of a reheater and superheater furnace respectively. Secondary furnaces 42, 70 fired by cyclone furnaces 46, 64, for example of the form described in Specification 598,141, are disposed below respective chambers 24, 26, the hot gases flowing into the chambers through slag screens 54, 72. From the upper part of the chamber 24 a lateral pass locating a convection reheater 82 and primary superheater 84 conveys gases to a main flue 124 in which is disposed an economizer 86. The floor 34 of the lateral pass forms the roof of the chamber 26 and of a short lateral pass conveying gases from that chamber into chamber 24, the short pass locating a secondary superheater 80. At maximum output, the furnaces 64, 70 and chamber 26 are designed to give excessive gas temperature at the entrance of the secondary superheater pass, whilst the design of the reheater furnaces 46, 42 and of the chamber 24 provides that optimum reheat temperature is obtained. The superheater and reheater absorbed heat and heat absorbed in steam generation are proportioned to maintain the correct steam temperatures over a wide range of loads by recirculating cool flue gas withdrawn by a fan 120 from the flue 124 to the secondary furnace 42 through a dampercontrolled duct 128 and to a region in chamber 26 adjacent the entrance to the secondary superheater pass through a dampercontrolled duct 132. The flow of recycled gases entering chamber 26 is controlled according to load conditions to bring the fresh gases therein to the temperature ensuring correct superheat whilst a constant reheat is maintained by oppositely varying the recycled gas flow to the furnace 42. In a modification, the superheater and reheater are disposed in parallel, damper-controlled gas passes extending upwardly from the secondary furnaces.

Title: Electric pulse multi-channel signalling systems
IPC: H04J3/00
Filed: 1946-03-22
Abstract: 609,789. Multiplex pulse signalling. STANDARD TELEPHONES & CABLES, Ltd. March 22, 1946, No. 8932. Convention date, April 2, 1945. [Class 40 (v)] In a pulse multiplex signalling system, the signal is applied to a number of channels in multiple, the number of channels depending on the degree of delineation of the modulation envelope required. The outputs of the signal sources 1-5 of a pulse multiplex system are connected to the fixed contacts of a series of switches 6-11, each corresponding to a pulse modulation signal channel. The moving contact of each switch is connected to the corresponding pulse modulation unit 12-17, which is rendered operative in turn by an associated phasing unit 18-23. The phasing units 18-23 are all controlled by a synchronizing source 24, which also determines the common repetition frequency of all channels and provides marker pulses, which are fed to the mixer 25 together with the channel outputs. At the receiver, the detected pulses are fed to demodulators 31-36 which are controlled by the output of the marker pulse selector 30 and the associated time adjusters 37-42 to accept only pulses of the appropriate channel. The output of each demodulator 31-36 is fed to the moving contact of one of switches 43-48, the fixed contacts of which are connected in multiple to the signal reproducers 49-53, corresponding to the signal sources 1-5. The signal from a single source 3, say, may be connected to any number of pulse modulation channels, each having the same repetition frequency but different phases. If channels having suitable phasing are used, the signal from source 3 is transmitted on a multiple channel having an effective pulse repetition rate equal to the number of single channels used times the P.R.F. of a single channel.

Abstract: 127,949. Dehn, F. B., (Bell & Howell Co.). June 4, 1918 Affixing by adhesives.-Apparatus for use in splicing the ends of strips of kinematograph film consists of two clamps in which the ends of the strips are secured; the clamps are arranged side by side, and one of them is movable in relation to the other whereby the ends of the strips are sheared and brought together, one overlapping the other. The lower member 27 of one clamp is secured on an arm 26 projecting from the standard of the machine, and the upper member 46 is carried on the end of a lever 45 pivoted on an axis 25 and rocked by a link connexion with a treadle lever 55. Both members 68, 75 of the other clamp are movable, being carried on the ends of arms 67 and 73 mounted to rock on the axis 25. The arm 73 is connected to a treadle lever 86, and the arm 67 carries a locking lever 93 which may be moved by hand to lock the arm to the stationary standard or to the arm 73. The upper and lower members of the two clamps abut against each other, but the upper member 75 overlaps the lower member 68, and the lower member 27 overlaps the upper member 46. In its lowered position the upper surface of the member 68 is level with that of the member 27. The stationary member 27 is fitted with a sliding plate formed with a pair of prongs adapted to engage the perforations in the opposite edges of the film ; the plate is movable vertically by a spring-controlled handlever. Assuming the upper members of both clamps to be in the elevated position and the member 68 in its lowered position, the end of the right-hand strip is laid thereon with the end perforations impaled on the prongs 41. The member 75 is now lowered to clamp the film after which the two members of this clamp are elevated together. The left-hand strip is now laid on the member 27 with its end perforations impaled on the prongs, and the member 46 is lowered to clamp it. The other clamp is now moved downwards, and the ends of the two strips are sheared, the one between the edges of the members 46 and 75 and the other between the edges of the members 27 and 28, and the overlapping ends are pressed together in close contact. When the right-hand clamp is elevated the exposed ends of the strips may be bevelled by a scraping-tool so that when cement is applied and the ends again returned into contact with each other the splice will be flat and accurate.

Filed: 1943-06-08
Abstract: 569,729. Reinforced concrete. FORSSELL, C. A. June 8, 1943, No. 9219. [Class 20 (iv)] Concrete is reinforced by bars fitted with anchoring rings which are connected to the bars by means of wedges, the latter engaging with a portion of the bar which has its original rolled surface unchanged and being driven in longitudinally of the bar between the bar and seats formed as grooves in the inside of the ring, the surface of each seat having a shape as if it were generated by a straight line moving parallel with itself. In the construction shown the anchoring ring is secured to the reinforcing rod 4 by wedges 5 tapering in one direction and wedges 6 tapering in the opposite direction, the ring being formed with tapered grooves to receive the wedges. The outer cylindrical surfaces 8 of the wedges are smooth and bear against the smooth bore of the ring, while the inner faces of the wedges are roughened to ensure a firm grip on the reinforcing iron which may also have a roughened surface. The engaging surface may be coated, by means of salt water for instance, to cause them to bond together. The parts are secured together in such manner that the wedges do not move relatively to the reinforcing iron. Thus the ring may be held firmly against the surface of an anvil, the wedges and reinforcing iron then being driven together into the ring. In a modification, Figs. 4 and 5 (not shown), the grooves in the ring are rounded to receive wedges of crescent-shaped section. Where the ends of two reinforcing irons are to be joined the rings may have external screw threads upon which is screwed a pipe nut.
