Title: Apparatus for measuring humidity
IPC: G01N27/12
Filed: 1948-05-12
Abstract: 644,675. Tension-variable wire resistances. FOXBORO CO. May 12, 1948, No. 13053. Convention date, May 21, 1947. [Class 37] [Also in Group XXXVIII] In a humidity-sensitive device (Fig. 1), a sheet 4 of hygroscopic material has cemented to it a resistance wire element 2 bent into a series of loops 2a, which is connected through the supporting conductors 8 into one arm of a Wheatstone bridge also comprising resistances 16, 18, 20. Initially the bridge is balanced by adjustment of resistance 16, and variations in ambient humidity produce changes in the physical dimensions of the sheet, which apply a variable physical strain to the resistance element. The consequential changes in resistance unbalance the bridge, which may be rebalanced by readjustment of the resistance 16, calibrated to indicate relative humidity. Errors due to variation of the resistance element with ambient temperature are counteracted by giving the resistance 18 the same temperature coefficient as the resistance element, and exposing it to the same temperature. The sheet may be of cellophane, paper, cardboard, or photographic film, and the resistance element may be of " Constantan," " Advance " or " Elinvar " (Registered Trade Marks). In a modification (Fig. 2, not shown) a pair of identical resistance elements with their axes mutually at right angles are cemented to a sheet of material (such as Fourdrinier machine paper) having anisotropic humidity-expansion characteristics, and the elements are connected in adjacent arms of a Wheatstone bridge. The humidity of a moving web, which may be of the same material as the sensitive sheet, may be measured by placing the latter in a chamber of the kind described in Specification 555,303, having one open side positioned to face the moving web. Humidity variations may be recorded by a resistance indicator-recorder of the kind described in Specification 625,189, [Group XXXVIII].

Title: Improvements in or relating to the recovery of gold from aqueous cyanide liquors
Inventor: AVESTON JOHN
IPC: C01G7/00
Filed: 1955-05-06
Abstract: Gold-bearing aqueous cyanide liquor containing the complex cyanide of copper, iron and nickel is treated with a weakly basic anion-exchange resin derived from cross-linked polystyrene having primary, secondary or tertiary amino groups at the exchange position to preferentially absorb the aurocyanide, which is thereafter recovered by elution with a solution of an inorganic compound, preferably a 2M alkali metal or ammonium thiocyanate aqueous solution.  The resins preferably have at the exchange positions, the group -CH2NRR1, where R and R1 are hydrogen, methyl, ethyl or b -ethylamine, R and R1 being the same or different.  According to an example, an aqueous cyanide solution containing nickel, iron and copper and 3 p.p.m. of gold was passed through a column of cross-linked polystyrene resin in chloride form, the resin having at the exchange positions the group -CH2N(CH3)2. The gold was concentrated in the upper part of the column together with minor amounts of nickel, copper and iron, and on elution with two molar aqueous sodium thiocyanate, gold, nickel and copper were recovered; the thiocyanate eluate was then subjected to electrolysis when gold (and any silver if present) was electrodeposited on the cathode.  After electrolysis the thiocyanate solution was returned for elution of a further batch. Had any zinc been present it could have been eluted from the column prior to the elution of the gold by means of a very dilute aqueous hydrochloric acid solution, e.g. 0.1 N.  Further examples relate to absorption on resins having at the exchange position the groups -CH2NH2, -CH2NH.CH3, -CH2N(C2H5)2, and -CH2NH-CH2-CH2-NH2 respectively.

Abstract: 650,122. Compound sheet materials. WALDRON, W., SCHOFIELD, P. J., and IMPERIAL CHEMICAL INDUSTRIES, Ltd. May 14, 1948, No. 13263. [Class 140] [Also in Group XXIX] Flexible containers for fuel oil or other liquids for aircraft or vehicles have as their wall a compound sheet material comprising a sheet of an elastomer having a fabric reinforcement lightly bonded thereto so that, under abnormal stress such as an impact which ruptures the reinforcement, the bond breaks down in the abnormally stressed area and permits the elastomer sheet to stretch without restraint. The elastomer, which has an elongation at break of 200 per cent or more, may be rubber, a synthetic rubber such as a polymerized substituted butadiene or a copolymer of butadiene and acrylonitrile, or a polyvinyl resin. The fabric may be cotton, wool, linen, silk, glass fibre, nylon, or wire mesh. The adhesion may be effected by wetting the elastomer with a solvent, attaching the fabric to the sticky surface, and, if necessary, curing. The containers may be made by applying sections cut from sheets of the composite material to a former, the fabric and elastomer being separated at the edges to allow a direct bond between the elastomer sheets, and the overlapping fabric layers subsequently stuck down. Alternatively, sections of elastomer may first be assembled upon a former, and a fabric layer subsequently secured thereto. Specifications 569,064, [Group XXIX], and 598,392 are referred to.
