Patent GB-446277-A (GB)
Title: Improvements in or relating to the manufacture of hydrocyanic acid
IPC: C01C3/02
Filed: 1934-10-25
Abstract: Hydrocyanic acid is obtained by reacting at elevated temperature one or more gaseous or vaporous hydrocarbons, nitric oxide, and one or more of the following gases: nitrogen, carbon dioxide, water vapour or oxygen, in the presence of a catalyst comprising one or more metals of the platinum group. Temperatures of 800--1400 DEG  C., are suitable.  Suitable gas mixtures may be obtained by mixing hydrocarbons with the gaseous oxidation products of ammonia with or without the separation of their water content.  The hydrocarbons which may be employed include methane, acetylene, ethylene, ethane, butane, propane, or their mixtures, natural gas, coal gas, coke oven gas, illuminating and fuel gases and the vapours of liquid hydrocarbons.  Suitable catalysts are platinum, rhodium, palladium, osmium, ruthenium, iridium and their alloys, especially alloys of platinum with rhodium or palladium.  These catalysts may be employed in the massive form, say as a wire net or screen, but preferably in the supported form on heat resistant non-metallic material such as asbestos, silica, alumina, &c.  A suitable catalyst support may be made by separately precipitating silica gel and alumina gel, mixing the gels, and drying and igniting the mixture.  If oxygen is present in the mixture, a larger proportion of hydrocarbon will be necessary. The hot exit gases should be cooled as rapidly as possible to 600 DEG C., or below.  The gases may then be scrubbed with sulphuric acid to remove ammonia, cooled to condense out water and scrubbed with water to remove the hydrocyanic acid, the condensed water being added to the scrubbing water.  Preferably, the hydrocarbon content of the gases is adjusted until the optimum yield of hydrocyanic acid is obtained.  Examples are given.

Title: Improvements in or relating to relay systems
Inventor: GARGINI ERIC JOHN
IPC: H04N7/10
Filed: 1954-10-28
Abstract: 769,591. Distributing music &c. ELECTRIC & MUSICAL INDUSTRIES, Ltd. Oct. 28, 1955 [Oct. 28, 1954], No. 31090/54. Class 40 (4). In a relay system for sound and/or television programmes a number of carrier oscillations each modulated with signals of different programme content, are fed over the relay network together with one or more additional oscillations, each receiver which is selectively operable to reproduce a desired programme including means responsive to the additional oscillation (or one of them) for heterodyning a selected modulated carrier wave. As shown, the distributing unit 1 includes a master oscillator 3 which delivers 18 kc/s. to a harmonic generator 4 and to an adding unit 5. The output of the harmonic generator is applied to six filters 5a to 5f which select the third to eighth harmonics respectively and apply them to modulators 6a to 6f fed by sources 7a to 7f of the sound signals of six television programmes, the outputs being applied to the adding unit 5. The video section 12, which handles the vision signals in like manner, includes a master oscillator running at 4 Mc/s. and the second to seventh harmonics are used to produce vestigial side band signals for the six vision signals. Each receiver 2 derives its signals from a pad 16 and applies them to low-pass filter 17 and high-pass filter 18, the former passing the modulated sound carriers and the 18 kc/s. oscillation, and the latter the modulated vision carriers and the 4 Mc/s. oscillation. Filter 19 separates out the 18 kc/s. oscillation and applies it to a harmonic generator 20, the harmonic selector 22 being operable to select any one of the third to eighth harmonics. The modulated sound carriers are applied to a synchrodyne demodulator 21 to which the selected harmonic is also fed to produce as output the selected programme signals, which are amplified at 23 and applied to the loud-speaker 24. The vision carriers are dealt with in like manner, but the harmonic selector 27 has a phase correcting control 27a and the filter 29 is adjustable so that its pass-band just embraces the desired modulated carrier, the adjusting means being ganged with the harmonic selectors 22 and 27. In a modification, unmodulated oscillations, one per programme, are distributed and one is selected at the receiver and used as the local oscillation in a superheterodyne receiver to produce intermediate frequency signals, in known manner, from the desired programme's modulated carrier.

Abstract: 1530252 Texturising yarns HEBERLEIN MASCHINENFABRIK AG 26 July 1977 [29 July 1976] 31265/77 Heading D1F A fluid jet for intensively texturising (whirling and looping) a synthetic multifilamentary yarn comprises a main or whirling chamber followed by an expanding passageway between the internal wall of which and a (part) spherical surface of a guide element is formed an annular passage or slot which guides and accelerates the air stream and through which the textured yarn is delivered. In the operation of the nozzle of Fig. 1, yarn 7 is introduced into guide passage 2 in a duct 1 in a body 14 whence it reaches a whirling chamber 3 fed through at least one radially directed bore 4 with compressed air whereby the yarn filaments are agitated. The yarn and air pass on to a nozzle 9 the passageway 11 of which has along its length a cross-sectional area which is larger than that of the spread cone of the air stream emanating from chamber 3. In the nozzle 9, a guide element 13 providing a hemispherical surface facing the chamber 3 forms an annular slot 12 with passageway 11 and after passing through the zone of least width in the slot 12 the textured yarn emerges and is taken-up at 8. The element 13 is contained in a tube 18 carried by a flexible limb of a U-shaped member 17 fixed to a support 15 mounted on a journal 16 in a bearing in body 14 so that axial and rotational movements thereof enable the shape and dimensions of slot 12 (and, therefore, the form of the texturisation) to be varied and assist in removal of element 13 from passageway 9. In the modification of Fig. 2, a concave surface 13" is provided by a frustrum of element 13 which is carried by an adjustable pivotable lever 21.

Title: Improvements relating to devices for interrupting electric current
IPC: H01B3/38
Filed: 1935-11-13
Abstract: An insulating material suitable for use in situations exposed to electric arcs, under the action of which the material gives off gas or vapour, consists of artificial resin containing nitrogen as a chemical constituent.  The material is preferably one having the nitrogen combined with hydrogen in the molecule, for instance a carbamide resin such as those known under the Registered Trade Marks "Pollopas" and "Resopal".  In some cases there may be added fillers such as ammonium carbonate, ammonium acetate, ammonium alum, hydrazine compounds, or urea, which may be dissolved in the resin, or incorporated in the colloidal state or in the form of grains. Alternatively, stable metal oxides, of the earth or alkaline earth metals, for example, or fibrous material such as cellulose or asbestos thread, or animal fibres such as hair, wool, silk, leather, skin, or horn may be used as fillers. The resins may be made by moulding or pressing with subsequent heat treating, or by casting, and may be given a metal or other core for mechanical strength.  A layer of resin may be applied, before hardening, to supports of hard paper, hard fabric, fibre, or ceramic or other material.  When an insulating member with resin filler is employed, the former may comprise fibrous material held together by a binder which is the same or as similar to that used for the protective layer, for example, hard paper or carbamide resin.  Rods and tubes may be made by winding paper, cotton, linen, wool, or silk saturated with the resin, and pheno-plast is employed where considerable mechanical strength is necessary.  Specification 354,174, [Group V], is referred to.
