Title: System for detecting transpositions of elements within a pulse signal
IPC: H04L1/20
Filed: 1962-10-04
Abstract: 948,568. Electric selective signalling systems. STANDARD TELEPHONES & CABLES Ltd. Oct. 4, 1962 [Oct. 4, 1961], No. 37527/62. Heading G4H. A circuit, Fig. 1,for testing a serial pulse train such as Fig. 2(a) I, II or III to see whether every long pulse 14 is followed by a long gap 15 and whether every long gap is preceded by a long pulse comprises the components shown, the monostable triggers having reset times equal to one and a half times the duration of a short pulse, and if either of the two conditions is not satisfied it produces error indicating output pulses. The monostable triggers are turned on-low output-unless already on by positive going changes at their inputs. The operating principle of the circuit is that the output switching circuit 12 receives the differentiated input pulses superimposed upon a D.C. level set by bi-stable trigger 9, which is so controlled as to go on at about the middle of the first long pulse or gap, and to go off again only if a long pulse is followed by a long gap. Any differentiated input pulse superimposed upon the high D.C. level of the trigger causes error indicating output pulses.

IPC: F23N5/08
Filed: 1959-11-05
Abstract: 962,800. Flame monitors. BABCOCK & WILCOX Ltd. Nov. 1, 1960 [Nov. 5, 1959], No. 37546/59. Drawings to Specification. Heading G1A. A flame monitor comprises means responsive to flame radiation to produce a constant and a fluctuating component of electrical output with measuring means responsive to each of these. A photo-cell directed on to the flame of an oil burning boiler is connected in a circuit to produce two D. C. voltages, one proportional to the steady light component of the flame and the other to the amplitude of its fluctuating component, the latter being obtained by rectification of the current through the cell. Each is supplied to one of two coils at right angles to each other which form a moving coil instrument indicating the quotient of the two voltages, so that the sensitivity of the monitor is unaffected by attenuation due to dirt of the light reaching the cell. In another embodiment the cell is directed towards the flame of the lighting up burner of a boiler and in the absence of this flame light reflected from the main flame by the walls of the combustion chamber reaches the cell. Each component voltage in this embodiment is supplied to a moving coil with its own pointer, the two movements being mutually at right angles in one instrument, to provide information on the combustion conditions. Additionally the voltages may actuate relays to operate alarms, or indicators, or controls relevant to lighting up procedures. Specifications 780,653 and 853,816 are referred to.

Abstract: 1,161,992. Making moulds of relief surfaces. SOC. CIVILE D'ETUDES ET DE RECHERCHES ARTISTIQUES ET GRAPHIQUES. 22 Aug., 1966 [20 Aug., 1965; 26 May, 1966], No. 37567/66. Heading B5A. [Also in Division B6] A mould of the relief surface of a pictorial work is produced by applying to the surface a layer of hardenable material (e.g. epoxy resin), followed by a layer of tightly woven fabric adapted to follow the contours of the surface of the work, a further layer of hardenable material and at least one further layer of reinforcing fabric of a more coarse texture than the tightly woven fabric, and separating the work and the mould only when the hardenable material has become partially hardened. A frame 18, Fig. 3, and a base 20 support a plate 11, bearing a pictorial work on its upper surface, fixed to the base by screws 22 engaging in bushes 14 in the rear of the plate. A uniform layer 23 of epoxy resin is applied (e.g. by brushing) followed by glass fibre fabric layer 24, a further resin coat and then a layer 25 of glass fibre fabric of more coarse texture. Further layers of fabric 26 alternating with other layers of resin are then applied. Frame 18 is closed by perforated lid 27, having apertures 28 which communicate with feed conduits 29, and channels 30 located opposite the most important elements of relief of the painting. Needles 31 are inserted into channels 30 to pierce the mould. The resin is then polymerized, the mould separated from the painted work, the needles withdrawn and the mould stoved. The mould is suitable for the vacuum forming of thermoplastic sheets which have been printed to provide a reproduction of the markings on the surface of the pictorial work. This process forms the subject-matter of Specification 1,161,991. The plate 11 which bears the pictorial work may comprise a painter's canvas backed by alternating layers of resin and reinforcing glass fibre fabric.

Title: Process for absorbing carbon monoxide and/or diolefines from gases and vapours
IPC: B01D53/34
Filed: 1930-11-04
Abstract: Carbon monoxide and/or diolefines are recovered from gases or vapours by bringing them into contact with a neutral solution of a cuprous salt, such as cuprous chloride or formate, containing a substance which prevents the formation of cupric salt, e.g. a reducing agent such as hydroxylamine hydrochloride, hydroquinone, sulphites, or stannous chloride.  The neutral solvent for the cuprous salt consists for example of an alkali or alkaline-earth metal or magnesium salt dissolved in a neutral liquid as water or p  alcohol.  The absorbed compounds may be recovered by heating the liquid, e.g. to 40-80 DEG C., or by applying reduced pressure, or both.  In the case of mixed gases, the components may be separated by fractional release under reduced pressure.  The separation of the addition compounds may be prevented by working temperatures above 10 DEG  C., and by using concentrated solutions, especially of the alkali or other salt used to form the neutral solution.  The separation of the carbon monoxide addition product may also be avoided by the addition of an acid amide, e.g. urea or acetamide to the solution.  The use of iron in the apparatus is avoided since this would precipitate the copper, and the apparatus is preferably made of stainless steels, lead, or the like.ALSO:Diolefines are removed from gases or vapours by bringing them into contact with a neutral solution of a cuprous salt, such as cuprous chloride or formate, containing a substance which prevents the formation of cupric salt, e.g. a reducing agent such as hydroxylamine hydrochloride, hydroquinone, sulphites or stannous chloride.
