Title: Improvements in or relating to the dyeing of elastic fabrics and in apparatus therefor
IPC: D06B3/32
Filed: 1935-06-11
Abstract: Elastic fabrics composed of, or containing, rubber threads are, during the dyeing process, subjected to an elongation of about 15 per cent or more in the longitudinal direction and also, if desired, to a certain extent in the transverse direction, to decrease the cross-section of such threads and facilitate access of the dyeing liquid around them.  The process may be carried out in a Jigger type of dyeing machine, <PICT:0451532/IV/1> with braking means k, l on the free-wheel rollers c, d powerful enough to produce the elongation required.  Curved transverse stretcher bars f<1>, f<2> are provided, one on each side of the vat a, to stretch the fabric b transversely both before and after immersion in the dye vat.  These stretcher bars may be carried at the opposite ends of frames pivoted on spindles f, and fabric-guiding rollers g<1>, g<2> are placed adjacent the stretcher bars f<1>, f<2>.  The angular position of the frame is adjustable by micrometer screw control to regulate the amount of transverse stretch produced.  In order to prevent periodical increases and decreases of elongation in the elastic fabric during the dyeing treatment, the two guide rollers g<1>, g<2> may be coupled together by a chain and toothed gearing.  Alternatively, the braking action may be automatically rendered uniform as the material unwinds from one roll and winds on the other, by using a weight acting on a lever which is moved automatically thereon to adjust the brake in accordance with the variation in diameter of the work on the roller as the fabric is unwound.  In a further form of apparatus, the rollers c, d are made of minimum diameter and the speed of the roller from which the fabric is being unwound is regulated by a brake controlled by p  a governor geared to the roller to maintain the latter at a uniform speed.  Reference has been directed by the Comptroller to Specifications 21397/04, 4295/08, [both in Class 15], 150,750 and 229,824, [both in Class 15 (i)].

Title: Improved Manufacture of Titanic Oxide from a Substance containing it.
Inventor: WADE HAROLD
IPC: C22B34/12
Filed: 1916-11-22
Abstract: 106,428. Wade, H., (Titanium Alloy Manufacturing Co.). Nov. 22, 1916. Titanium oxide; alkali titanates; iron-alkali-sulphides.-In the process of treating titaniferous materials such as ilmenite by fusing with an alkali sulphide or an alkali sulphate and carbonaceous materials and then treating the melt with a dilute acid to dissolve the iron compounds, the melt is maintained in a liquid state until it has had time to separate into two layers, an upper layer of iron-alkali sulphide and a lower layer of alkali titanate. The layers may be withdrawn from the furnace at different levels or successively, or the whole charge may be poured into deep moulds and maintained liquid until the layers form; after cooling, the upper layer, being brittle, can be readily broken away from the lower layer. The titanate layer is treated with dilute acid to remove the iron and alkali as in the known processes, much less acid being required. Nitre cake is preferably used in the melt, and may be first fused with the titaniferous material until thickening occurs, after which the carbon is added and the furnacing is effected.

Abstract: 1,131,347. Luminescent screens. SYLVANIA ELECTRIC PRODUCTS Inc. 13 April, 1967 [18 April, 1966], No. 17074/67. Heading C4S. [Also in Division H1] A method of forming a colour C.R.T. screen having two adjacent phosphor patterns comprises depositing a liquid suspension of a phosphor in a photo-sensitive material, exposing selected portions to light to polymerize the material which has a sufficiently high organic solids content to provide, over unexposed areas, a thin layer polymerized by ambient light and heat, of insufficient thickness to provide phosphor adhesion, depositing another photo-sensitive layer upon which dry particles of a second phosphor larger than the first are deposited, a second pattern being formed by exposure to light. A screen having three patterns of phosphor dots is formed using ZnCdS suspended in PVA and water-sensitized with NH 4  dichromate and applied to a rotating substrate. Unpolymerized material is washed away and dry-powdered rare earth activated rare earth vanadate or oxide heat phosphor is deposited on a sprayed layer of the same photosensitive material having a lower solids content. The second pattern may be formed by exposure before or after powder is deposited. A third pattern of ZnS phosphor may be deposited using either of the above methods and the screen baked to remove organic materials.
