Title: An instrument-board indicator of the temperature of the water contained by the cooling radiator of a motor-car
IPC: G01K5/16
Filed: 1923-04-28
Abstract: 215,945. Owen, W. J., and Smith, A. R. April 28, 1923. Tell-tale apparatus. - For indicating the temperature of the water in an automobile radiator a mercury thermometer T mounted in an aluminium watertight container K within the radiator R, has a number of contacts a-e let into the thermometer stem and connected to an indicator comprising a number of lamps A-D mounted in a casing L on the dashboard of the vehicle. The contact e is connected to one terminal of a battery H the other terminal of which is connected to a switch S on the casing L. The switch S is in the circuits of the lamps A, B, C but not in that of lamp D. The arrangement is such that as the temperature rises the lamps light up in succession, the temperature being indicated by the number of lamps which light up when the switch is closed. The lamp D is preferably red and lights up, without operation of the switch, when the water in the radiator is near its boiling point.

Title: Improvements in cast iron as a friction surface
IPC: C22C37/10
Filed: 1951-05-17
Abstract: A cast iron having a high resistance to wear and a high coefficient of friction has a network of hard phosphorus eutectic embedded in a matrix of a soft constituent, e.g. pearlite.  A metal of such structure may be obtained by pouring a metal consisting of 2.9-3.3 per cent. carbon, 1.4-2.2 per cent. Si, 0.6-1 per cent. P, 0.25-0.4 per cent. Mn, 0.12-0.18 per cent. S and the balance Fe, into an undried greensand mould and controlling the cooling from 1280 DEG C. to 600 DEG C. so that the time taken is 7-12 minutes and is inversely proportional to the silicon content-1.4 per cent. silicon corresponding to 12 minutes and 2.2 per cent. silicon to 7 minutes; the structure of the metal will then be a matrix of pearlite, which may contain some fine graphite flakes, in which is embedded a phosphorus eutectic.  The amount of phosphorus eutectic present is dependent on the thickness of the section, a thin section requiring a higher content of eutectic than a thick section.  The network may have a mesh of 2-20 to the sq. mm.

Title: A Device for X-Ray Radiometric Determination of the Concentration of Elements in Test Specimes

IPC: G01N23/203
Filed: 1967-03-16
Abstract: 1,176,209. Photo-electric X-ray analysis. VSESOJUZNY NAUCHNOISSLEDOVATELSKY INSTITUT MINERALNOGO SYRIA. March 16, 1967, No.12401/67. Heading G1A. In determining the concentration of an element in a sample containing other elements by measuring the continuity of characteristic radiation emitted by the element when the sample is irradiated by X-rays, absorption of the characteristic radiation by the sample is governed by its effective atomic number which is evaluated by irradiating the sample with #-radiation and, measuring the #-radiation scattered off the sample; a correction can then be made in the measured intensity of the characteristic radiation. In one arrangement Fig. 1 (not shown) a manually moveable shutter permits depending upon its position either #-radiation or X-rays from a nuclear bombarded target to irradiate the sample. In a modification Fig.2 (not shown) the shutter carries a source of #-radiation to which the sample is exposed when being shielded from X-rays. In both cases a single detector measures in turn the characteristic radiation emitted and the #-radiation reflected. In a further arrangement Fig. 3 (not shown) two portions of the same sample are carried upon a rotatable disc which is moved to present simultaneously one portion to the X-rays and the other to the #-rays: emitted characteristic radiation and reflected #-radiation being measured by separate detectors.

Abstract: 1521183 Stretching fabrics E C A SCHWARZ 29 March 1976 [31 March 1975] 12521/76 Heading D1S  A non-woven web 12 of orientable polymeric material is biaxially stretched by passing the web 12 into the nip 14 between rollers 16 having intermeshing peripheral corrugations extending parallel to the axes thereof to effect longitudinal stretching and passing the longitudinally stretched web 20 into the nip 24 between rollers 26 having intermeshing peripheral corrugations extending perpendicular to the axes thereof to effect transverse stretching. The web 12, Fig. 1, of staple fibres or continuous filaments, is fed from a roll 10 to the rollers 16 and is maintained against the lower roller 16 by press rollers 21. After passage through the nip 14, the web is stretched longitudinally by tension rollers 22 rotating with a peripheral velocity greater than that of the rollers 16. The web 20, Figs. 4 and 5, passes into the nip 24 and is held against the lower roller 26 by press rollers 30. The web 32 is stretched laterally by tenter chains or curved rolls 34 and is collected on a roll 36 rotating at the same peripheral velocity as the velocity of feed of the web 20 to the rollers 26. The longitudinal and lateral stretching steps may be repeated alternately through multiple passes. The grooves or corrugations on the rollers 16, 26 are sinusoidal in section and are as fine as possible to prevent the fibres breaking and the web losing tensile strength. Examples refer to biaxially stretching a randomly laid web of partially oriented polypropylene fibres, a spun-bonded web of continuous polyester fibres and a latex bonded randomly laid web of polyester fibres.

Title: Improvements in the mordanting & dyeing of wool
IPC: D06P3/20
Filed: 1924-05-22
Abstract: Wool is dyed with chrome dyestuffs, such as hematine, fustic, quercitron bark, osage orange, alizarines, gallocyamines, Mordant Yellow, Brilliant Alizarine Blue R and Palatine Chrome Black, by a process of sequence dyeing in which it is mordanted with 1-2 per cent of its weight of potassium or sodium bichromate in presence of lactic and hydrochloric acids in the proportion of 1 part of hydrochloric acid (32 DEG  Twaddell) and 1 1/2 parts of lactic acid (50 per cent) for each of bichromate, a dyestuff being then added to the bath and a weak acid.  Prior to the addition of the dyestuff the bath may be rendered slightly alkaline.  In an example the wool is entered into a boiling bath containing 1 per cent of sodium bichromate, calculated on the wool, and the corresponding quantities of lactic and hydrochloric acids, after 45 minutes the bath is made alkaline with sodium carbonate, and after a further 5 minutes the dyestuff is added and the bath made acid by addition of acetic or other acid.  If the wool is not initially neutral the necessary proportion of acid or alkali is added to the mordant bath before the above proportions of reagents are employed.  Specifications 18896/96 is referred to.  The Provisional Specification is not limited to the above proportions of reagents and further states that a separate dyebath may be employed.
