Abstract: 1452420 Measuring volume of suspended particles LEEDS & NORTHRUP CO 11 Sept 1974 [3 Oct 1973] 39682/74 Heading G1A [Also in Division G2]  The volume of particles suspended in a fluid is determined using apparatus comprising a source which projects a collimated light beam through the fluid, optical focusing means collecting forward scattered light, a spatial filter and a detector receiving the light transmitted through the filter. The filter has a central region 27 which blocks unscattered light, on intermediate region 36 where light transmission is proportional to the reciprocal of the angle of scatter and an outer region 32 with a higher transmission than that which would result from the conditions applying at 36, to compensate for the vignetting effect of the outer limits of the filter. A region 28 may be provided to compensate for loss caused by the central region. As shown, light from laser 12 passes through a length d of the sample and is scattered by the particles. The scattered light is collected by L 1  which focuses light scattered from all particles of the same size on to the front face of lens L2, and then on to detector D. The spatial filter is placed on the front of lens L2.

[Also in Division F4] A combined solar heater and cover for a swimming pool comprises a panel consisting of an upper translucent sheet 11 spaced from a lower, currugated, heat-absorbent sheet 7 and conduit means for passing water from the pool between the sheets whereby the water is heated by solar heat. The lower sheet 7 may consist of galvanized corrugated iron with the uppermost surface blackened. In use, several panels, each having rope lifting handles (13), and supported in an inclined position on timbers (2, 3), are arranged over the pool when the latter is not being used for swimming; hence reducing radiation heat losses. A perforated conduit (9) is positioned along the upper ends of the panels and water pumped from the pool to the conduit (9) trickles downwardly over the corrugations from which it runs back into the pool. When the pool is required, either sufficient panels are removed, or the whole unit is moved to the side of the pool. Solar heating of the pool water may be continued in this position, temporary extensions being made if necessary to the corrugated sheets to conduct the heated water into the pool.

Abstract: Rubbery polybutadiene containing at least 85% cis 1,4 addition is obtained by contacting 1,3-butadiene under polymerization conditions with a catalytic amount of a catalyst selected from the group consisting of (1) a catalyst which is formed on mixing an organometallic compound having the formula RnM where R is an aryl, aralkyl, alkaryl, cycloalkyl, alkylcycloalkyl or cycloalkylalkyl radical, M is zinc, mercury or aluminium and n is an integer equal to the valence of M, and titanium tetraiodide, (2) a catalyst which is formed on mixing an organometallic compound having the formula R3Al where R is as above, p  titanium tetraiodide and titanium tetrachloride, and (3) a catalyst which is formed on mixing an organometallic compound of formula R3Al where R is as above, a compound TiXm where X is chlorine or bromine and m is an integer from 2 to 4 inclusive, and iodine.  Lists of specific catalyst systems are given.  The polymerization is usually carried out in the presence of a diluent, e.g. paraffins, aromatic hydrocarbons and cycloparaffins, and the polymerization temperature may vary, for example, from -100 DEG  to 250 DEG F.  The polymerization process may be carried out batchwise or continuously and in the former process on completion of the polymerization reaction, the total reaction mixture is treated to inactivate the catalyst and recover the polymer, e.g. the polymer can be recovered by steam-stripping the diluent from the polymer or an alcohol can be added to the polymer mixture.  An antioxidant, e.g. phenyl-beta-naphthylamine, may be added to the polymer solution prior to the recovery of the polymer.  In Example 1, the catalyst is formed by mixing triphenyl aluminium and titanium tetraiodide and in Example 2, diphenyl zinc is mixed with titanium tetraiodide.

Abstract: 1,176,589. Winding and unwinding coiled material. LEAR SIEGLER Inc. 27 Aug., 1968 [3 Oct., 1967], No. 40929/68. Heading D1T. [Also in Division G3] A turntable 12 supporting reels of wire 16, is capable of being driven at two different speeds by an electric motor 24. This speed control results from first and second resistance 40, 42 in the motor circuit, one or other of these resistances being rendered effective by switch means linked to an arm 52 acted on by the wire 18 from the reels 16. As illustrated wire is being paid off and for this purpose the resistance of higher ohmic value is normally rendered effective by the switch 44 to cause the turntable to rotate at a pre-determined slow speed. Should the wire be drawn off faster than it is delivered by the turntable, the wire 18 will become tensioned in a manner rotating the arm 52 towards the turntable 12 and so cause the switch 44 to substitute the resistance of less ohmic value in the motor circuit thus causing the turntable to speed up. The resistances 40, 42 are adjustable.
