Title: Improvements in or relating to machines for cutting continuous filaments into staple fibres
IPC: D01G1/04
Filed: 1938-04-20
Abstract: 513,794. Stapling continuous filaments. KINSELLA, E. April 20, 1938, No. 11849. [Class 120 (iii)] Continuous filaments are cut into staple lengths by feeding them to the centre of a rotating member, delivering them to the periphery of the member, through a passage extending from the axis thereof to the periphery, carrying the filaments on emergence from the rotating member into an air stream moving in the direction of rotation of the member and at such a speed that the filaments stand substantially erect from the member and bringing the emerged portion of the filaments periodically into contact with a cutting element so as to cut off the portion as a bundle of fibres; the filaments may be cut by one or more rotary knives or by a band knife, the air stream is supplied partly through the passage carrying the filaments and partly at one or more fixed points disposed shortly before the cutting point, and the air stream may be augmented immediately after the cutting so that the cut fibres are carried away from the cutting point. As shown the rotary member 5 is mounted on a shaft 8 in a spiral casing 2 the filaments emerging from the radial passage 15 in the member 5 being cut at the nip of a pair of overlapping rotating disc cutters 7 disposed in extensions 6 at each side of the casing with the nip disposed on the axes of the shaft 8. The casing 2 increases in radial depth, in the direction of rotation of the member 5, from a point immediately after the cutting device to a point immediately before it to provide a substantially uniform air speed round the casing and immediately before the cutting point the air speed is increased by the provision of holes 24, 25 at each side of the casing so as to lift the emerging filaments clear of the members 5; the cut fibres are carried away through a duct 3 connected to the casing 2 by air admitted through a slot 48 formed between the flange of the casing 2 and the flange of the duct 3 which is connected by a pipe to a suction head. The periphery of the spiral casing may comprise a series of pivoted vanes between which air admission openings are formed, the openings being varied by moving the pivoted vanes or a series of openings in the casing may be covered, to vary the size of the openings, by'a slotted sliding shutter surrounding the periphery of the casing. The bundle of filaments is fed to the axial passage 16 of the member 5 through a duct 26 fed by a pair of rollers 27, 28 ; the roller 27 is a steel surfaced measuring roller driven from the shaft 8 through change gearing and the bundle of filaments is nipped against the roller 27 by the rubber-covered roller 28 carried in a spring-controlled pivoted bracket 43, the spring 44 being connected to the bracket through a quick-release hook 46 and lever 47.

Title: Improvements in the manufacture of sulphonated castor oil
IPC: C11C3/00
Filed: 1931-04-23
Abstract: Castor oil or mixtures of castor oil with other vegetable oils or fatty acids derived therefrom are sulphonated at temperatures above 0 DEG  C. but below 35 DEG  C., in the presence of sulphur dioxide or substances which yield the latter, e.g. sulphites or bisulphites, but excluding liquid sulphurous acid.  The sulphonation may be followed, before neutralizing but preferably after washing, by an oxidation treatment.  In an example, castor oil is sulphonated with sulphuric acid at 30 DEG  C. while stirring and introducing a stream of sulphur dioxide.  Alternatively, instead of passing in sulphur dioxide, the castor oil is agitated with powdered sodium bisulphite or anhydrous or crystalline sodium sulphite, and treated with sulphuric acid. After washing, the sulphonated oil is oxidized by means of air, oxygen, nitric acid or hydrogen peroxide and finally neutralized. Specification 294,621, [Class 2 (iii), Dyes &c.], is referred to.

Title: Improvements in or relating to radio and like telephone transmitter installations
IPC: H03C1/62
Filed: 1937-04-27
Abstract: 494,588. Wireless transmittingsystems. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., and ZEPLER, E. E. April 27, 1937, No. 12041. [Class 40 (v)] Liability to undesired control by noise in a voice-operated blocking transmitter is avoided by providing a second microphone, located at a suitable distance from the speech microphone which is subjected to noise but not speech. Transmitter valve 1 in the absence of speech is prevented from oscillating by the shunt control valve 6 which is in the conductive condition. Noise voltages produced by microphones 12, 15 are rectified at 14, 17 and produce opposing D.C. voltages across resistances 10, 11. Speech acts only on microphone 12 and produces a resultant negative bias, which applied to the grid 20 renders valve 6 nonconducting and permits oscillation of the transmitter 1.

Title: Manufacture of o-sulphobenzoic acid
IPC: C07C309/58
Filed: 1943-07-24
Abstract: o-Sulphobenzoic acid is obtained by reaction of an o-halogenbenzoic acid with a salt of sulphurous acid in the presence of copper or a copper salt.  Advantageously, the o-halogen-benzoic acid is dissolved in water and an alkali to form a solution very weakly alkaline or neutral to litmus, and the reagents are heated under pressure with stirring.  In an example, an aqueous solution of o-chlorobenzoic acid, made very weakly alkaline with soda, is treated with an aqueous solution of sodium sulphate or of another sulphite containing a small proportion of copper sulphate and the whole is heated under pressure within 4 hours to 170-175 DEG  C. and so maintained with stirring for 10 hours; the cooled product is extracted with hot water and the extract is made acid to Congo red by adding hydrochloric acid, and evaporated to isolate the product, after filtering off crystallisations of inorganic salts and unchanged chlorobenzoic acid.

Title: Process for the production of highly crimped regenerated cellulose fibres from viscose
IPC: D01F2/06
Filed: 1951-05-24
Abstract: Highly crimped regenerated cellulose fibres are produced from viscose by (1) extruding viscose into a coagulating bath or the first of two or more coagulating baths, the specific electrical conductivity of this bath or of the first bath bearing a ratio to that of the viscose of 0.85 : 1 to 1 : 0.85; (2) stretching the filaments so produced, while they travel through an air or steam bath or a further coagulating bath, to such an extent that the elastic limit of the filaments is just not exceeded; and (3) allowing the filaments to contract freely in a tension-releasing bath, the specific conductivity of which bears a ratio to the specific conductivity of the electrolyte contained in the filaments when they enter the releasing bath of 0.7:1 to 1 : 0.7. The coagulating bath may contain 25-980 grams per litre of sulphuric acid, the corresponding concentrations of sodium hydroxide in the viscose being 4.8-8.5 per cent.  In an example viscose of 12-13 Hottenroth degrees of ripeness and containing 8 per cent. cellulose, 7 per cent. of caustic soda and 35 per cent. of carbon bisulphide is extruded into a coagulating bath at 43 DEG C. containing, per litre, 115 grams of sulphuric acid, 280 grams of sodium sulphate, and 5 grams of zinc sulphate, to form filaments which are elongated 28 per cent. by passage at 70 DEG C. between two pairs of rollers through the vapour space above a boiling water bath.  The filaments are cut and the cut pieces are allowed to shrink freely in a water bath at 70 DEG C.  In other examples filaments similarly produced are allowed to shrink freely in a detensioning bath in the uncut condition.

Abstract: <PICT:0945301/C1/1> In the production of glass in a continuous melting furnace divided into melting and refining compartments by a dam, the latter is cooled to improve its durability, and the consequent tendency to creat descending glass currents is nullified by producing an ascending glass flow on the upstream side strong enough to maintain a flow of glass over the dam and to prevent incompletely fused glass passing thereover.  As shown, the dam 3 made of electrically fused refractory of good heat-conductivity extends through the hearth 4 and is cooled by gaseous jets 6. Further jets 5 induce the ascending glass flow, which may also be produced by electrodes or mechanical devices such as screws or propellers.  Other jets 9 induce an ascending flow downstream of the dam. Modifications, Figs. 1 and 4 (not shown), rel yon the nature of the dam material to produce therein a cooling effect, or, as in Fig. 3 (not shown), the jets 6 play into recesses in the dam.  The latter may be disposed between a refining compartment and a conditioning compartment.
