Title: Device for indicating and/or recording the material components in x-ray spectral analysis
IPC: G06F7/68
Filed: 1962-05-18
Abstract: 973, 047. X-ray spectral analysis. SIEMENS & HALSKE A. G. May 18, 1962 [June 8,1961], No. 19200/62. Drawings to Specification. Heading G1A. In an arrangement for the X-ray spectral analysis of a substance, for example an alloy, the electrical output from the analyser is fed to a com puter having a digital store containing information about the slope and zero point of the linearised transposition curves or curve segments of the individual material components so that the percentages of the materials in the substance can be computed and indicated or recorded. The transposition curve data may be selected manually or by a programming device. Where it is necessary to divide a curve up into a plurality of linearised sections the data for the required section may be selected automatically in accordance with the amplitude of the input. The computer store may derive its information from a punched tape. The output of a counter tube detector is preferably fed in the computer to a step-down counter giving a reduction corresponding to the slope of the transposition curve and then passed to a further stage taking into account the zero point of the curve.

Title: Data rpocessing circuitry
IPC: G06F12/16
Filed: 1974-05-02
Abstract: 1426671 Error checking circuits INTERNATIONAL BUSINESS MACHINES CORP 2 May 1974 [4 June 1973] 19274/74 Heading G4A Error checking circuitry includes a multistage data register individual stages of which are set in accordance with stage select and state signals in response to a later occurring trigger signal, and means to produce an error signal if signals dependent on the parity of the register contents before and after the trigger signal are not in the same relationship as the state signal and the state of the selected stage before the trigger signal. Two or more registers may be provided (only on, REG B, shown), a register stage selected by coded stage select signals 14 (which are decoded at 16) in a register selected by register select signal 12 being set to a state determined by state signal 60 on the later occurrence of trigger signal 62. The initial state of the selected stage is read out via selector 30 (controlled by decoder 34 which receives the stage select signals 14) and compared with the state signal at exclusive-OR 40. The parity of the contents of all the registers is supplied by exclusive-OR 44 to exclusive-ORs 46, 48, the arrangement being such that in the absence of trigger 62 latch 50 has an output equal to its input so that the output of exclusive-OR 54 is the same as that of exclusive-OR 46. Subsequently when the trigger 62 occurs the output of latch 50 is frozen and is compared with the parity signal from exclusive-OR 44 to produce an error signal, gated at 56 by the delayed trigger, in accordance with whether the new parity indicates that the required state change and only the required state change has occurred. If a failure occurs in the stage select decoding circuitry 16 such that the wrong register stage is selected and its state changed then the parity output 44 will change but the output of selector 30 will not (decoder 34 still functioning correctly) so that the output of exclusive-OR 46 will change (normally it does not since the parity 44 and selector 30 signals change in unison) and exclusive-OR 52 will produce an error signal. The arrangement also detects unwanted state changes in a non- selected register since exclusive-OR 44 produces a parity signal for the contents of all registers.

Abstract: 1,012,662. Pneumatic separators. SCHUCHTERMANN & KREMER-BAUM A.G. FUR AUFBEREITUNG. May 18, 1962 [June 2, 1961; Aug. 11, 1961; Aug. 23, 1961; Sept. 11, 1961], No. 19346/62. Heading B2H. A pneumatic separator for separating dust from fine grained materials, e.g. moist freshly mined pit coal, comprises a dust collecting chamber 5 which is closed at the base by a flat bottom 7, and a grain discharge funnel 4 extending downwardly through the bottom 7 and disposed beneath a separating chamber 1 to which the material is fed from a rotating spreader plate 3 as a thin veil, the dust being drawn upwardly and into the chamber 5 by the air current produced by rotation of a fan 2, a mechanical dust discharging device being provided in the chamber 5, by means of which the separated dust is stripped off the side walls and bottom of the chamber 5 and is fed to a dust outlet. In the embodiment shown in Fig. 1, the fan 2 is driven in a hollow driving shaft down which the material is fed to the plate 3. The funnel 4 is mounted for rotation on the wall of the separating chamber 1 at 14, and in the bottom 7. The air is circulated through the chambers 1, 5, the fan 2 and a vane ring 6 in the funnel 4. The funnel carries scrapers 8, 9 which strip dust from the wall of the chamber 5 so that it falls on to a rotating plate 10 and is thus moved to an outlet 12 by a stationary stripper 11. Scrapers 48 may be fitted to the fan 2 in place of the scrapers 9. In the embodiment shown in Fig. 2 strippers 17 secured to a ring 19 are rotated above the bottom 7 of the chamber 5 by a pinion 22 which engages with upstanding bolts 21 on the ring 19, and the dust is fed to an outlet 18. Scrapers 25 may also be provided for the wall of the chamber 5, but where the inclination of this wall to the horizontal exceeds 75 degrees, the scrapers 25 may be dispensed with. In the embodiment shown in Fig. 3, strippers 26, 26<SP>1</SP> are secured to a spider 27 rotated by gearing 33. Dust seals 34, 34<SP>1</SP> are provided, but dust passing through the seals is removed by scrapers fixed to the spider 27. The funnel 4 has a lower section which may be raised to allow replacement of the seals.
