Filed: 1968-07-26
Abstract: 1,240,877. Foundry moulding sand. BRITISH NON-FERROUS METALS RESEARCH ASSOCIATION. 24 July, 1969 [26 July, 1968], No. 35923/68. Heading C3N. A foundry moulding sand composition comprises a particulate refractory material admixed with an aqueous fluid, which fluid comprises, in solution, or in stable suspension or dispersion, an alkali metal silicate, a water-soluble oxidizing agent compatible with the metal silicate, and from 9-40%, by weight, on the weight of the fluid, of a readily oxidizable organic material, which is compatible with the alkali metal silicate and the oxidizing agent. The alkali metal silicate used is preferably sodium silicate and of these that having a SiO 2 : Na 2 O weight ratio of 2À0- 3.3 is advantageously used. The aqueous fluid preferably contains from 50-80% by weight, particularly 60-75%, of the commercial sodium silicate solution, whilst the amount of oxidizing agent is preferably 1-15% by weight. The water-soluble oxidizing agent should be compatible with the alkali metal silicate in the sense that it does not prevent the alkali metal silicate from exercizing its function as a sand binding agent and examples of such oxidizing agents are the nitrates, chromates, dichromates, permanganates and chlorates of alkali metals, particularly of sodium and potassium. Mixtures of such agents may be used. Examples of the readily oxidizable materials are starches, dextrine, celluloses, gums, natural resins, sugars and carbohydrate materials, ligneous materials, synthetic polymers, e.g. polyethylene and polystyrene, and hydrocarbon materials, e.g. coal-tars pitch and wood tars and these materials may be used separately or in admixture. Sucrose is a preferred material and a preferred composition includes sucrose and a mixture of a major proportion of sodium chlorate and a minor proportion of sodium dichromate as the oxidizing agent. The aqueous fluid preferably contains from 6-10% of added water but percentages above or below this range are also envisaged. The term # and is used to cover particulate refractory materials in general, e.g. silica, zircon, chrome, olivine or sillimanite. The aqueous fluid may be added to the sand in a wide range of proportions, e.g. 2-8 parts by weight per 100 parts by weight of sand. Small amounts 0À5-2À0% by weight, of bentonite and soluble dextrine may be added to the sand to improve its green strength.

Abstract: 1283241 Double beam spectrophotometers PYE Ltd 5 May 1970 [18 July 1969] 36376/69 Heading G1A [Also in Division G2] In a null-type double beam spectrophotometer having an attenuator 4 of range N in one beam and an attenuator 6 of range M in the other beam, N being greater than M, the attenuator 6 is adjustable according to the intensity difference between the two beams at the detector 9 and the attenuator 4 may be either locked in a stationary position or coupled to be driven with the attenuator 6 in such a way that as the attenuation in one beam is increased, that in the other is decreased. The null position of the attenuator 6 corresponds to the absorption of a sample 7, and the position of the attenuator is indicated on a pen recorder 16. The recorder is also coupled to the drive mechanism of a mono-chromator 2, so that a plot of absorption v. wavelength is obtained. The exit beam from the mono-chromator is directed alternately through the sample cell 7, which may contain a solution, and a reference cell 5, which may contain the corresponding solvent by a rotating sectored mirror 3. A variable attenuator 10 is provided for coarse adjustment of the system prior to the measuring process. Each attenuator 4, 6 comprises a tapered aperture Fig. 2 (not shown). In a first position of a range switch 52, the attenuator 4 is locked in its minimum attenuation position by a relay 53, in which case only the attenuator 6 moves under the control of the output from detector 9, e.g. photo-multiplier to cover a limited absorption range. In a second position of the range switch the two detectors are coupled together by an electromagnetic device (39, 40) to allow for a wider range of absorption by the sample.
