Title: An improved apparatus for measuring the surface temperature of objects emitting heat radiation
IPC: G01J5/52
Filed: 1953-03-24
Abstract: 726,581. Measuring heat radiation. MUNKER, T. March 24, 1953 [March 24, 1952], No. 8033/53. Class 40 (3). In order that for over a small range the temperature indicated by a heat radiation sensitive device shall be independent of changes in the surface condition of the object whose temperature is required, the sensitive device is subjected to the direct radiation from a surface area of the object and to the radiation from an auxiliary source and reflected by the area, the auxiliary source being such that the radiation received by the sensitive device equals the black-body radiation. It is stated that for a range of 25 C. above or below the temperature for which the auxiliary source is set, the inaccuracies caused by changes in the surface condition are negligible. In a radiation pyrometer, the radiation from a carbon filament lamp 9 is reflected by a semi-permeable mirror 7 through a lens 5 on to the object 16. The direct and reflected radiations from the object 16 are focussed by the lens 5 on to a photocell or photo-electric resistance 6 surrounded by a cooled casing 2. A standard radiator 12, preferably an electrically-heated body of the same material as the object 16, radiates through a regulator 13 and a lens 14 on to the photo-cell 6. A slotted disc 19 driven by a motor 17 ultimately passes the radiations from the object 16 and the radiator 12 to the photo-cell 16, the electrical output of which is passed through an amplifier to a phase bridge controlling a central zero meter. A regulating voltage is also applied to the phase bridge from the field windings of a generator 18 whose armature is on a common shaft with the disc 19 and has projections equal in number to the slots in the disc. The phase bridge output may be used to generate control signals. In a modification, the standard radiator 12 also serves as the auxiliary source.

Patent GB-491259-A (GB)
Title: Improvements in the manufacture of artificial filaments, yarns and similar materials
IPC: D01F2/28
Filed: 1937-03-19
Abstract: Artificial filaments, yarns, and similar materials are produced and treated so as to have in addition to a flat cross-section, a denier which varies along their length.  They may also be subjected to a crinkling treatment.  The variation in denier may be obtained by stretching the materials to a varying extent in a regular or irregular manner during the course of their production or in an after-treatment operation.  The production of filaments of flat cross-section may be effected by use of a spinning solution containing a lower proportion of cellulose derivative than that required for filaments of bulbous cross-section, e.g. less than 24 per cent of cellulose acetate in acetone.  By incorporating plasticizers such as paradichlorbenzene in a cellulose organic derivative solution, filaments of flat cross-section may be obtained. Crinkling may be effected by treating the filaments with hot aqueous media such as, hot water, wet steam, or hot solutions of soap, sulphonated oils, sulphonated higher fatty acids or alcohols, or aliphatic sulphonic acids.  The lustre of the materials may be altered during the crinkling treatment.  Sugars or salts may be added to the aqueous liquor to preserve the lustre during the crinkling operation.  The treatment with hot aqueous media may be combined with other crinkling treatments, e.g. yarns may be twisted, the twist set while the yarn is travelling, and the yarns then untwisted.  The process may be applied to continuous or short length filaments. Filaments may be cut between an operation for crinkling by setting twist and removing it, and a crinkling treatment with hot aqueous media. Two or more yarns of low twist may be twisted together to a high degree, the high twist set, and the doubled yarn untwisted and left with a small degree of reverse doubling twist.  The flat filaments may be of cellulose acetate or other cellulose ester or ether.  Yarns may contain also other fibres or filaments of natural silk, wool, cotton, or regenerated cellulose.  Staple fibre yarn may be doubled with a continuous filament yarn.
