Patent GB-354852-A (GB)
Title: Improvements in or relating to apparatus for indicating and/or recording the change in volume of gases
IPC: G01N7/04
Filed: 1930-05-20
Abstract: <PICT:0354852/III/1> <PICT:0354852/III/2> A gas analysis apparatus comprises a pump so arranged that at each downward stroke of the piston a definite volume of gas is expelled from the lower end of the barrel through an absorbent solution and p  into the space at the upper end of the barrel.  The latter space is of smaller volume than the former by reason of the thickness of the piston-rod, so that the unabsorbed gas is more than sufficient to fill it and the surplus volume is measured in a suitable device which is in communication with the upper end of the pump.  Alternatively, the residual gas may be confined to the upper space of the pump and its increase in pressure measured.  On the upward stroke of the piston the residual gas is expelled to the atmosphere from the upper space and a fresh charge is drawn into the lower space.  Fig. 6 shows the pump, comprising a barrel 2 and piston 4 driven by a crank 7 from any source of power.  The barrel oscillates on bearings 2<1> within a case 3.  Valve facings 11, 12 on the barrel and the case respectively are provided with ports 13, 14, 15, 17, 19 which open and close as required as the barrel oscillates.  Fig. 1 shows the complete apparatus.  The tank for the absorbent is shown at 25.  The volume-measuring device comprises a bell float 26 counterbalanced by a weight 38 carrying a pen 30 which records the tests on a clockwork-driven drum 31.  An indication is also given by the scale 29.  In this modification the valve between the pump and the bell float is always open.  In an alternative modification the residual gas is confined to the pump and its pressure is measured by a known type of recording apparatus, e.g. that described in Specification 128,793, [Class 106 (ii), Dynamometers &c.].  In this case the valve between the pump and the pressure recorder is only opened for a short time when the piston is in its lowest position.  The recording pen thus remains at the figure given by each test until the next test is completed.

Abstract: 545,604. Titanium pigments. BRITISH TITAN PRODUCTS CO., Ltd. Oct. 30, 1940, No. 15865. Convention date, Oct. 31, 1939. [Class 95] In a process for improving the technical properties of a titanium pigment by preparing an aqueous slurry thereof and precipitating a water-insoluble white silicate in situ within the slurry by reaction between a water-soluble alkali silicate and a water-soluble metal compound, the pigment slurry is maintained at a temperature between 60‹C. and 80‹C. during the precipitation of the insoluble silicate. By operating within this temperature range, the precipitated silicate uniformly associates itself with the pigment particles. Specified silicates which may be so precipitated are those of magnesium, zinc, cadmium, aluminium, yttrium, zirconium and cerium, and, usually, the amount of silicate precipitated is up to about 10 per cent. by weight of the titanium pigment. The treated pigment particles are dewatered, dried and lightly pulverized. Examples-are given of the treament of commercially pure titanium dioxide pigments, though the process may be applied to the titanium dioxide pigments containing extenders such as barium sulphate or calcium sulphate, and to titanates and other titanium pigments. According to the Specification as open to inspection under Sect 91, the insoluble silicate need not be formed ih situ in the pigment slurry, and the association 'of the pigment with the silicate may be carried out in the cold. This subject-matter does not appear in the Specification as accepted.
