Abstract: 1,258,081. Masted lift trucks. WESTING- HOUSE BRAKE & SIGNAL CO. Ltd. 15 Jan., 1969 [19 Jan., 1968], No. 2930/68. Heading B8H. In a masted lift truck having a tiltable mast, one of the front wheels, and each of the rear wheels have strain gauges 1, 2, 3 incorporated in their suspensions, the signals from the strain gauges being fed to a circuit in which the signals are compared and which actuates a warning device or imposes a limitation on control means for the apparatus when the truck approaches an unstable condition. In a first embodiment, Fig. 4, the circuit includes a summing circuit 4 and a proportioning circuit 5 which feeds a signal corresponding to a predetermined proportion, x%, of the sum of the loadings of strain gauges 1, 2 into a comparator circuit 6 which is constructed to produce an output instability signal at 10 when the input from circuit 5 exceeds the lesser of the inputs from the strain gauges. Similarly, a sidewaysinstability signal is produced from a comparator circuit 9 when the input from a proportioning circuit 8 exceeds the lesser of the inputs from the strain gauges 2, 3. In a second embodiment, Fig. 5 (not shown), the criterion for instability is that the smaller loading of two strain gauges shall not be greater than a predetermined proportion of the larger. In a third embodiment, Fig. 6 (not shown), the criterion is that the larger loading of two strain gauges shall be less than a predetermined proportion of the sum of the loadings.

Abstract: 1,265,366. Delaminating mica. REED INTERNATIONAL Ltd. 3 July, 1970 [13 May, 1969]. No. 24415/69. Heading C1A. Mica is delaminated by heating to partially remove combined water followed by treatment in a quenching bath and then in a treating bath, one of the baths being H 2 O 2  and the other being aqueous alkali. The heating may be at 700‹ to 850‹ C. The alkali may be an alkali metal hydroxide, an alkaline earth metal hydroxide, ammonium or substituted ammonium hydroxides. Muscovite or mica waste may be used as the starting material. The mica may be allowed to cool slightly, for instance to 600‹ C. before quenching. The mica may be drained between the two treatments. After treatment in the treating bath, the mica may be drained and washed and may then be mechanically agitated in water or other aqueous medium. Mica paper may be made from the product with the use of binders such as curable synthetic resins.

The flue gas may be derived from the burning of coal or oil, and is preferably contacted with the absorbent at a space velocity of 2000 to 15,000 v./v./hr. at a maximum pressure drop of 5 inches water gauge. The absorbent may be a copper or copper oxide on a carrier, e.g. alumina, zirconia-kieselguhr, silica and silicaalumina. The preferred reducing gas for the regeneration process is a steam/hydrogen/CO/ CO 2  mixture derived from the catalytic reform-  ing of methane, other suitable reducing gases include CO and hydrocarbon mixtures in the C 6 -C 14  range. The absorbent may be given an inert gas purge at the start and finish of the regeneration stage. The regenerated SO 2  gas, after oxidation of the residual H 2  and CO to water and CO 2 , and drying is converted to SO 3  and worked up into sulphuric acid by conventional means.
