Patent GB-212035-A (GB)
Title: Improved manufacture of catalytic agents
IPC: B01J21/08
Filed: 1923-01-17
Abstract: A colloidal solution of a catalytic material is applied to a porous gel such as silica gel having pores of such size that the water content of the gel at 30 DEG  C. when in equilibrium with water vapour at a partial pressure of 22 m.m. will be about 21 per cent. The silica gel prepared as described in Specification 136,543 is suitable, and the catalytic materials applied to it may be for instance metallic copper, silver, gold, iridium, osmium, palladium, and platinum, and the oxides of copper, iron, aluminium, zinc, cobalt, and nickel.  The pores of the gel are substantially filled with water (that is to say the actual water content of the gel is about 30 to 40 per cent) at the time of treatment with the colloidal solution, and the treated gel, after washing if desired, is then dried.  The drying may be effected as described in Specification 136,543.  The filling of the pores with water prevents the breaking up of the granules owing to too rapid adsorption of the colloidal solution and causes the catalytic material to penetrate to a comparatively small depth so that it is mostly distributed over a layer near the surface.  In an example, a colloidal solution of platinum obtained by reducing chloroplatinic acid with formaldehyde, is poured over silica gel and the mixture is stirred and heated over a water bath for thirty minutes.  It is stated that when a 7 per cent sulphur dioxide-air mixture is passed over 20 grams of this catalyst at 300 C.C. per minute, 90 per cent is converted into sulphur trioxide. Specification 212,065 also is referred to.

Title: Method and apparatus for modifying textile fabrics
IPC: D06C29/00
Filed: 1943-02-01
Abstract: The dimensions of a fabric composed of yarns consisting of or containing thermoplastic material are modified by engaging spaced points along the boundaries of the fabric by means of holding members while continuously moving the fabric in a longitudinal path, bringing the members into effective distances defining the desired final dimensions of the fabric along a portion of its path, heating the fabric to its softening point along that portion to effect partial coalescence of the yarns at their points of crossing and to cause the fabric to attain the desired dimensions and then setting the fabric by reducing its temperature below the softening point.  The heating of the <PICT:0565180/IV/1> fabric may be prolonged to permit equalization of internal stresses and uniform distribution of heat effects before setting. As shown, the fabric passes from a roll 2 through a tentering frame 3 comprising heating sections 4, 5 and a cooling section 6 to a take-up device 7.  The pins or clips 8 carried by chains 9 are moved along guideways 10, 11 having swivel joints 36, 37 by cam discs 12 - 15.  The distances between adjacent courses are adjusted by the right- and left-handed screws 28, 29, 30.  The supply roll 2 is provided with a drag device comprising clamping blocks 39, 40 and a stationary pin 45 projecting therebetween whereby any desired degree of tension may be placed upon the fabric which is also interlaced between rotatable bars 47, 48 at the ends of the machine to maintain it flat.  Heating coils 50 may be provided above and below the fabric during the preheating stage 4.  The heating stage 5 may comprise a number of sections provided with coils 52.  The fabric is cooled at 6 by cold air through a duct 53.  If desired, cold or hot water, steam or other liquids may be sprayed onto the fabric at any stage of the process.  A temperature of 150 DEG  F. or upward is satisfactory in the preheating stage for fabric comprising yarns of copolymers of vinyl chloride and vinyl acetate.

Title: Method of measuring the thickness of bodies with the aid of x-rays
IPC: G01B15/02
Filed: 1932-01-25
Abstract: 383,478. Gauging - apparatus. MœLLER AKT.-GES., C. H. F., 24, R÷ntgenstrasse, Hamburg, Germany. Jan. 25, 1932, No. 2282. Convention date, Feb. 6, 1931. [Class 106 (ii).] A method of determining the thickness of a body consists in placing an X-ray source and a fluorescent screen or photographic film in definite positions on opposite sides of the body, interposing in the path of the beam from the ray-source to the screen or film one or more marks which project discrete shadows on the screen or plate, and calculating the required thickness from the size of the shadow or distance apart of the shadows. For any given arrangement of the various parts, calculation of the thickness may be avoided by providing on the screen or on a separate member a scale from which the thickness may be read off directly as the scale distance covered by the shadow, or between the shadows. The marks may be carried by one or more distance members attached to the ray-source and/or the screen to space them from the body. Fig. 1 shows an arrangement in which the raysource 1 and fluorescent screen 4 carry distancemembers 2, 6 to space them from the body 10 whose thickness is to be determined. The members carry ray-absorbing marks 3, 7 as of lead or tungsten, and they are laterally spaced so that the marks cast discrete shadows 5, 8 on the screen 4. From the data indicated in the figure the thickness x of the body is calculated from the equation x = db - a which is s derived from the geometry of the arrangement. A modification is described in which both marks are on the same side of the body as the ray-source ; and the equation for calculating the thickness is deduced. An apparatus for carrying out this second method comprises a ray-tube in an earthed metal envelope 20, Fig. 3, carrying distance-members 27, 28 and an applicator 21 comprising telescopic parts extended by a spring so that a disc carried by the lower part is pressed against the body 22. On the disc are stretched tungsten wires 25, 26 which cast shadows on a photographic film 23 laid against the body 22 and on a fluorescent screen 24 spaced from the body by distance members 29, 30. Calculation from the film record serves as a check upon that from the visual record obtained on the screen.
