Title: Method of and apparatus for collecting and analyzing particles contained in atmospheric air
IPC: G01V9/00
Filed: 1974-03-11
Abstract: 1461466 Separating and analyzing particles in gases BARRINGER RESEARCH Ltd 11 March 1974 [19 March 1973] 10696/74 Heading G1B Apparatus for separating particles from the air and analyzing them for predetermined constituents, e.g. during rapid geological surveys, comprises a collecting device 10 into which atmospheric air passes at a rate of at least 10 cu. m/min. and which contains a plurality of louvres 13 and 14 whereby much air is separated by passing through the gaps in the louvres whereas the particles, by virtue of their greater inertia, pass together with some of the air to the collecting manifold 15 wherefrom they are conducted through pipe 16 past a particle counter 24 and through a further "concentrating" device 17 Fig. 2, (not shown) to a pipe 25 from which the particle-laden air may take one of two paths, the first through valve 28 leading to a transfer block 39 in which the particles are transferred to a stream of inert carrier gas, e.g. argon, from a source 40, which passes to a quartz bottle 44 heated, e.g. to about 800C, by a resistance wire heater 45. There, volatile materials e.g. mercury and hydrocarbon radicals, are produced from the particles and pass in the gas stream to a resonance radiation cell 47 and a plasma tube 57 which, together with associated mercury vapour lamp 49, interference filter 50, electrodes 53 and photodetectors 52 and 56, may be used to determine such materials. The particles may alternatively pass through valve 29 to a nozzle 30 having diagonal air vents 31a which bleed off much of the air, allowing the particles to reach and be deposited on and adhere to a collecting band 32 which may have an adhesive or electrically charged surface. The band may be moved continually or intermittently and stored on a roll 34 (having, if desired, a second protective layer of material from roll 36 placed over its surface) so that the particles, which have been collected during any one of a series of specific periods of time, each not more than 15 seconds, can subsequently be analyzed by conventional techniques.

Title: Improvements in and relating to the production of finely divided phenolphthalein andcompositions containing the same
IPC: C09B67/54
Filed: 1930-04-04
Abstract: Phenolphthalein and compositions containing same.-Finely-divided crystalline phenolphthalein is made by precipitating an alkaline solution thereof with an acid in the presence of a colloid sufficient to delay precipitation but insufficient to form a thick gel on standing.  In an example, phenolphthalein is dissolved in caustic soda, diluted with an aqueous solution of acacia, indian gum, tragacanth, or agar-agar, and an excess of acetic acid added; after some delay the product is precipitated in finely divided form.  A more finely divided product which is even more active as a laxative is obtained if a solution of one or more of the derivatives of the reagents used in the preparation of phenolphthalein is mixed with the phenolphthalein solution before precipitation.  By this means compositions containing definite proportions of phenolphthalein may be prepared.ALSO:Compositions containing phenolphthalein in a finely divided state are prepared by precipitating an alkaline solution containing phenolphthalein and one or more of the derivatives of the reagents used in the preparation of phenolphthalein e.g. phenol and phthalic acid radical containing compounds, with an acid in the presence of a colloid sufficient to delay precipitation but insufficient to form a thick gel on standing. Protective colloids mentioned are acacia, Indian gum, tragacanth, and agar-agar.  By this means compositions containing definite proportions of finely divided phenolphthalein may be made.

[Class 12 (i).] Spindle thrust or journal bearings are loaded by hydraulic pressure obtained by way of a non- return valve, h or p, from a pump i having an adjustable relief valve j in its delivery system to limit the load to the minimum necessary for efficient running, the hydraulic fluid in the header g or in the space r being trapped by the non-return valve so as to constitute a rigid non-yielding abutment which resists any tendency of the spindle to overcome the hydraulic loading pressure. Fig. 1 shows a grinding spindle a the upper bearing caps e of which are loaded by the pressure of oil from a gear pump i on pistons d in the bearing casing. The relief valve j, past which oil is fed to the sight feed devices k and thence to the bearings, and the non-return valve h are arranged in a single casing. The thrust bearing o is loaded by oil pressure on a piston n, the non-return valve p causing a hydraulic lock in the chamber r should the spindle a tend to move axially. There may be an intermediate block f between each piston and bearing cap, or the piston may connect directly to the cap or itself form the bearing. One piston may be used for each bearing cap. Bleed-screws t may be slackened to allow entrapped air to escape. The invention is also applicable to vertical spindles. According to the Provisional Specification, each piston may exert a wedge action on bearing shoes, or each piston may have one or two points of connection with such shoes, and the pump may be replaced by a tank containing a piston actuated by spring or other means.
