Title: Improvements relating to air gauges for effective linear measurements
IPC: G01B13/10
Filed: 1955-06-08
Abstract: 793,376. Linear-dimension gauges. MERCER, Ltd., T., and WEATHERBY, D. J. June 7, 1956 [June 8, 1955], No. 16465/55. Class 106 (2). In a gauging element for an air gauge of the type in which a mechanical component intervenes between the air escape orifices and the work to be measured, a spring ring 9 suitably shaped to fit the bore to be measured and having projecting work feelers 17 occupies a position in which parts of its opposite surface are close to the air escape orifices 12, 13, and move closer to, or further away from them as the bore varies, so altering the back pressure or flow of the air. A cylindrical body 1 has a threaded nipple 2 to carry the air line and is of constant external diameter from this end to a step 3, from which the external diameter is smaller. A cup-shaped member 5, 6 screws on to the smaller end 4 of the body 1 and fits closely to it, but is of such a length as to leave an annular gap between it and the step 3. The spring ring 9 fits in this gap and is of slightly larger internal diameter than the external diameter of the part 4 of the body 1. The body 1 has an airway bored along a diameter in the medial plane of the ring 9 and this is fitted with two nozzles 12, 13, with their ends just below the internal surface of the ring 9. An airway 10 is bored in the body along its axis from the nipple 2 to the airway 11. Two grooves 20, 21, are formed in the surface of the larger part of the body as return airways and two flats 22, are made on the smaller section 4 to act as airways between it and the cup member 5, 6 communicating with bores 24 in the cup member 5, 6. The ring 9 is of the form shown in Fig. 2, having six flats 16, and two arcuate portions 14, 15 opposite the nozzles 12, 13, and carrying slugs 17 of tungsten carbide or other hardwearing material, which form the work feelers of the ring 9. The ring has a gap 18 on the diameter perpendicular to the airway 11, and a peg 19 fits in this to locate the ring in position relative to the body. 1. The instrument is calibrated by using master ring gauges or other means. In other forms of the invention it can be used to measure the internal diameter of a relatively short and wide hole, or the external diameter of a pipe or rod. The spring may have a thread on its surface in order to measure internally or externally threaded members.

Patent GB-562386-A (GB)
Title: Improvements in the production of textile materials
IPC: D06M13/08
Filed: 1942-11-27
Abstract: A fabric, yarn, or other textile material having a high sensitivity towards water, is obtained by treating a textile material having a basis of cellulose or cellulose ester with an alkali and an etherifying agent such that under the conditions employed the textile material retains its structure while the cellulose is substantially completely converted into a cellulose ether which is capable of being swollen or dissolved by cold water.  The fabrics may be employed for the manufacture of parachutes for minelaying, since in contact with sea or river water the material of the parachute will rapidly gelatinise and be dispersed and so will not remain as an indication of the existence and position of the mine.  Yarns or fabrics having a basis of cellulose may be subjected to the desired etherification with methyl chloride, dimethyl sulphate, or other alkylating agent, in presence of alkali.  Cotton yarns or fabrics may be soaked in concentrated caustic alkali solution and then pressed or centrifuged till the molecular ratio of alkali to cellulose is below about 10 to 1.  The materials are heated with methyl chloride in large excess, e.g. 6-12 or more times the weight of the dry cellulose materials to temperatures above 60 DEG  C. for several hours.  The product may be washed with hot water.  The etherification may be carried out on regenerated cellulose yarns or fabrics including those obtained from stretched and saponified cellulose ester materials.  The etherification may be applied to cellulose ester yarns or fabrics, the cellulose ester being both saponified and etherified by the reagents used.  Instead of a methyl cellulose, the cellulose ether textile material which is formed may be a water-soluble or swellable ethyl cellulose corresponding approximately to the monoethyl ether, or it may be a cellulose ether containing a hydrophilic substituent, e.g. a hydroxy-ethyl cellulose.  The Provisional Specification includes also the production of filaments and yarns by extruding a solution of a water-sensitive cellulose ether, e.g. a solution in water of a water-soluble cellulose ether, into a precipitating bath comprising, for example, acetone, or a concentrated solution of sodium hydroxide or sodium chloride.  Such yarns may be woven or otherwise made into fabrics.
