Abstract: 1,154,198. Electric selective signalling. A. M. JOUSSET, C. A. JACQUART, Y. H. LE GOFFIC, and J. E. MILON. 2 Aug., 1967 [3 Aug., 1966], No. 35504/67. Heading G4H. A converter for providing a digital indication of the mean power over an arbitrary time interval of a variable input signal at terminals 11, 12 (Fig. 1) includes a circuit 20 which samples the input signal regularly under the control of a pulse generator 3, a capacitor 1 being charged by the samples via a diode 5 and discharging via a constant current discharge circuit 30. A second capacitor 2 is connected to the terminals of capacitor 1 via a discharge circuit 40 which produces a partial discharge of the capacitor 2 at a current proportional to the instantaneous voltage across capacitor 1, a charging circuit 70 recharging the capacitor 2 when the voltage across it drops below a minimum level. A first counter 4 counts the number of times capacitor 2 is recharged and a second counter 8 counts the number of sample pulses from pulse generator 3. In the preferred embodiment in which a trigger circuit 50 switches when the voltage across capacitor 2 drops to its minimum level to cause a calibrated circuit 60 to feed a pulse to counter 4 and to block the discharge of capacitor 1 during this pulse, a threshold circuit 80 feeds an additional current to capacitor 2 when the input signal is weak to compensate for the discharge, an AND gate 91 being then blocked to prevent the sample pulses being accumulated. Transistorized circuitry (Fig. 2, not shown) is described for components 10, 20, 30, 40, 50, 60, 70 and 80 of Fig. 1.

[Class 78 (v).] In an excavator comprising a cable-drawn scraper bucket, the bucket is drawn by two approximately parallel cables adapted to be given a relatively longitudinal movement under control of the operator, so as to tilt the bucket laterally as for widening trenches. In Fig. 3, the cables 5, 6, pass from the bucket 3 over sheaves 20, 21, to drums 16, 17, adapted to be separately coupled to the driving shaft 15 and provided with band brakes.. Cams 22, 23, are connected respectively to the drums 16, 17, and project towards the other drum. In normal operation, the cams are diametrically opposed ; if one drum is braked, its cable lags behind the other cable until the two cams collide, the first drum being then driven by the second drum to drag the bucket in a laterally tilted position. Shock-absorbing means may be provided between the cams. In another form, Fig. 4, the cables pass to a common drum and the sheaves 20, 21, are carried by frames 24, 25, connected by levers 28, 33, and adapted to be given a parallel motion as by worm gearing 39, 40, and a screw 38 with safetyrelease means to limit the stroke.

Abstract: 302,282. K÷gel, G. Dec. 13, 1927, [Convention date]. Plates, films, and papers; diazotype processs. -Sensitive layers which yield positive prints from negative originals are prepared by mixing a ferric salt with a carbonyl compound capable of reacting with ferrous salts to form coloured compounds. The ferric compound may be ferric ammonium citrate, tartrate, or oxalate, or a mix-e ture of ferric chloride and ferric sulphate. The carbonyl compound may be a ketone, and as such are instanced quinones such as #-naphthoquinone-sulphonic acid, nitroso compounds or isonitroso compounds of #-carbonyl compounds of aliphatic, aromatic or aliphatic-aromatic nature. In an example, isonitrosoacetylacetone, isonitrosopropionyl-acetone and nitroso-#- naphthol are referred to. A binding-material such as gelatin or starch and bodies which serve to salt out or mordant the colouring-matter may be added to the layers. The Specification as open to inspection under Sect. 91 (3) (a) states also that if a silver compound is added, sepia prints are obtained.
