Abstract: 1476299 Atomic fluorescence spectroscopy NATIONAL RESEARCH DEVELOPMENT CORP 3 Oct 1974 [26 Oct 1973] 49969/73 Heading G1A In a non-dispersive atomic fluorescence spectroscopy apparatus the sample to be analyzed is placed in a notch 2 of a carbon filament atom reservoir 1 which is heated so that its temperature increases at a steady rate. The filaments electrodes 4 and 5 are supplied from the mains via a variable transformer 20 and a further transformer 21. As the filament heats up different atoms vapourize selectively at different temperatures. The resulting "cloud" is irradiated via cassegrain mirror systems 8 and 9 by two electrodeless discharge lamps 6 and 7 supplied from a micro-wave generator 24. The wavelength of the radiation from the two lamps is such that each excites fluorescence in at least one of the various atomic constituents being investigated. The resulting fluorescence is viewed via a further cassegrain mirror system 10 by a photo-multiplier 11. An oscilloscope 12 provides signal amplificated and read-out. Thus by observing the oscilloscope for "peaks" the presence of particular elements can be determined by the timing of their appearance.

Title: Circuits for the quality of a colour television signal
IPC: H04N9/083
Filed: 1971-10-28
Abstract: 1341139 Colour television NIPPON COLUMBIA KK 28 Oct 1971 [28 Oct 1970(4)] 50221/71 Heading H4F In a colour television camera using two striped colour filters to produce an image which when scanned gives rise to two separable colour component signals each modulated on to a subcarrier of frequency determined by the stripe spacing of the associated filter, an arrangement for reducing the effects of crosstalk due to partial overlap of the frequency bands of luminance and chrominance signals is provided. As shown in Fig. 13 the output from camera pickup tube 6 is fed to low-pass filter 7 to extract a luminance signal and to band-pass filters 8, 9 tuned to the two colour subcarriers. The colour signals pass via delays 10, 11 to subtractors 12, 13 which also receive correction inputs, their outputs then passing to a mixer 14 deriving the three primary colour signals. At rapid changes of luminance a circuit 15 differentiates the input signal and produces pulses of period t 0  (having a spectrum similar to that of luminance changes) which are processed at 16 to produce unidirectional pulses. These are transmitted via band-pass filters 20, 21 (similar to 8, 9 respectively) to produce signals which reduce at 12, 13 the effect of spurious cross-talk components. An arrangement for generating two sets of correction signals based on rapid chrominance changes in the two colour channels and applying them each to the other channel is described (Fig. 15, not shown); in this case the correction pulses each have widths (and thus spectra) chosen in accordance with the channel spacings. Fig. 22 (not shown) illustrates an arrangement in which the pulses generated by rapid luminance changes act to close a gate for a colour signal, to sample the delayed colour signal at a slightly later instant (when it is free of crosstalk components) and insert this sample in place of the blocked colour signal, the colour channel including an appropriate delay to enable this to be done.

Patent GB-506829-A (GB)
Abstract: 506,829. Cash registers. NATIONAL CASH REGISTER CO. Sept. 28, 1937 No. 26212. Convention date, Oct. 5, 1936. [Class 106 (i)] Totals, printing ; transfer mechanism.-The total - taking and transfer mechanisms of machines of the Shipley type, are now modified to dispense with the usual reset spider and associated linkages. The usual cam-oscillated driver 58, Fig. 1, is now connected by a latch 59 of usual construction to a differential arm 62, that is free on the sleeve 54 and in turn connected to a slotted nose 63 of the actuator 50 by a pin 65 projecting from the latch-supporting bell-crank. The actuator has the usual racks 51 for engagement bv the totalizer wheels 53, each rack having associated therewith the usual toothed arm 52 for increasing its effective length at transfer. Each arm is normally rendered ineffective by the abutment of a stud 102 thereon with an edge 101, Fig. 4, of a trip pawl 92 that prevents the arm from following the actuator to home position. At transfer, however, a tooth 89 on the totalizer wheel of lower order rocks a control lever 91 counterclockwise about its shaft 95, whereupon a shouldered offset arm 94 of the lever releases the trip pawl 92 of next higher order to the action of a spring 100. The edge 101 is thus removed from the path of the stud 102 of the toothed arm of higher order, which is thus rendered effective to add a unit into its associated totalizer wheel. The tripped pawl 92 is restored during the succeeding operation by a three-armed lever rocked by the driver. A total-taking operation involves the usual two cycles, at the beginning of the second of which the totalizer is engaged and its wheels rotated backwardly to zero where they are arrested by abutment with the control levers 91. The actuator associated with each totalizer wheel is also arrested and through the pin 65 breaks the latch 59 to arrest the differential in required position. Specification 8119/15, [Class 106 (i)], is referred to.
