Title: Improvements in and connected with silicated compositions
IPC: C04B28/24
Filed: 1938-04-04
Abstract: 505,710. Coating and plastic compositions. NIGHTINGALL, V. C. J. April 4, 1938, No. 10241. [Class 70] [Also in Groups III and XV] Coatings and moulded bodies are made by forming a mixture of finely divided zinc or, zinc alloy and an aqueous solution of a silicate, and converting the mixture to a substantially insoluble condition by and in the presence of carbon dioxide. The layer or article may be heated in an atmosphere of carbon dioxide, but preferably the mixture contains a bicarbonate and is subjected to heat to produce the carbon dioxide. The mixture may also contain fillers and other ingredients, such as basic oxides or hydroxides, e.g. magnesia and calcium hydroxide, a borate, e.g. borax, boric acid, graphite, metal oxides, e.g. zinc oxide and cork dust. In an example, a vehicle, comprising 100 parts by volume of an aqueous solution of sodium silicate of 1À4 specific gravity, 12 parts of an aqueous solution of sodium bicarbonate saturated at 60‹ F and 6 parts of an aqueous solution of borax, saturated at 60‹ F., is mixed with an equal weight of zinc dust and applied by brushing to a surface. The coating is allowed to set for about 6 hours and is then heated at 170-700‹ F. InÀa modification, the vehicle is applied first and then a layer of zinc dust is sprayed on. The insolubilizing may be effected without heat by applying to the set coating a solution, e.g. 10 per cent, of magnesium chloride or calcium chloride or a mixture of these. The heat treatment may also be omitted if the vehicle includes magnesium oxide and calcium hydroxide, e.g. 10 per cent by weight of each.

Filed: 1928-04-10
Abstract: 309,309. Weir, S. G. April 10, 1928. Calculatin.g-apparat2cs. - An appliance for ascertaining the effect of load and ballast on the draft and trim of marine vessels comprises a chart provided with draft and tonnage scales and having strings, rods or other indicators adapted to show the load, draft and trim when adjusted in relation to the scales. As shown in Figs. 1 and 2, a panel or frame 1 bears a squared chart 2, a tonnage scale a disposed in the middle of the chart, and side scales b of draft representing submergence at the bow and stern of the vessel. The scales are set in accordance with the rates of submergence in inches per ton of the ship and may read up to total tonnage and full draft. The scales, however, as shown are interchangeable the graduations being formed on tapes 4 passing around guide rollers to spools 6 on shafts 10 with squared ends 11 for operation by a key or handle. The tapes are kept taut by friction blocks 7 mounted on adjustable spring blades 8. To facilitate the choice of scales for a particular rate of submergence a table as shown in Fig. 6 is provided, the tonnage scale numbers being arranged across the top and bottom and the draft scale numbers down the sides, the space enclosed thereby being divided into squares and marked with the rates. Above the chart is arranged a number of indicators constituted of elastic string 12 connected at the ends to sliders 13 working in grooves 14 on the frame 1. The chart is provided with an auxiliary chart marked with a curve c from which the effect of a given load on the trim of the vessel can be read when the distance of the centre of gravity of the load from the mid-line of the ship is known. The curve may be plotted from results obtained by observation on a given load or by the formula 420<W>/A(1+6.91<Wh>/A) = S where A = Area of water plane of the vessel h = distance from the mid-ship section S = the submergence at the end towards which the load is applied.

Title: Resistance materials and methods of making the same
IPC: H01C7/04
Filed: 1940-06-21
Abstract: 540,844. Resistances. STANDARD TELEPHONES & CABLES, Ltd. June 21, 1940, No. 10706. Convention date, June 23, 1939. [Class 37] An electric resistance material having a negative temperature coefficient comprises the combined oxides of nickel, manganese, and cobalt, the resulting specific resistance varying between 1000 and 2x10<6> ohms/cm' depending on the relative proportions of the metals present. The halftemperatures (i.e. the temperature-range over which the resistance is doubled or halved) is below 70C throughout the above resistance-range and being in most cases within the limits of 140  and 20C, the range of measurement being taken as 0-25C. The Specification includes triangular curves showing lines of equal specific resistance and lines of equal half-temperature for all possible percentages of the oxides and the metals, so that, for a given specific resistance and halftemperature the percentage or percentages of each oxide or its metal element can be ascertained, and vice versa. Many numerical examples are given from these curves, Fig. 4-7 (not shown), and it is pointed out that high values of specific resistance are obtained for high nickel, manganese, or cobalt, and that half-temperatures of 30C or over are obtainable for low manganese (5-18 per cent) combined with relatively low nickel (4-30 per cent) and giving a wide resistance range. If the ratio of manganese to nickel varies between 1:1 and 12:1 a wide resistance-range is obtained with half-temperatures between 14 and 20 C. In manufacturing the resistances, the oxides in finely-divided state are intimately mixed and formed into bodies which are heated at temperatures of 800-1450C (the higher temperatures giving the lower resistance values) in an oxidizing, reducing, or inert atmosphere depending on the amount of oxide present and the resistance desired, the heat-treatment having no marked effect upon the half-temperature of the product. The bead of Fig. 1 is made by mixing the oxides into a paste with a binder such as a nitrate solution of one of the metals, for example, of cobalt, allowance for which is made in choosing the proportions of oxide. The head 10 is formed on platinum wires, dried and heat treated. In the disc of Fig. 2, the mixed oxides are pressed into a body 20 and heat treated, metal paste applied and leads 22 embedded therein. The unit is then heated to solidify the paste into electrodes 21 securing the leads. Alternatively the leads may be soldered to metal sprayed on to the solidified paste. The units may be enclosed in glass envelopes preferably evacuated to 10<-3> m.m. of mercury. A small bead of 0.03 in the diameter having a resistance 30,000 ohms at 25C and a half temperature of 18C. comprises 23 per cent NiO, 47 per cent Mn2O4, and 30 per cent Co2O3.
