Abstract: 707,118. Specific gravity estimating apparatus. POCHAN, R., and POCHAN, A. March 13, 1952 [March 17, 1951; Dec. 28, 1951], No. 6587/52. Class 97(3) The apparatus comprises a transparent tube adapted to contain a liquid to be tested, an hydrometer disposed in the tube, a circular line on the surface of the tube to define a fixed reference plane in which a reading of the liquid density is to be taken from the hydrometer scale, and means for bringing the level of the liquid to, and maintaining it at, a constant distance from said fixed reference plane. The apparatus shown in Fig. 2 comprises a transparent tube 1 which is filled by liquid via a funnel 20 to the top of an overflow pipe 23 for guiding excess liquid to a beaker 24, and a siphon 25 with a bevelled end maintains the liquid at this level 7 which is at a constant distance from a plane defined by a circular line 6 in which the optical axis of a lens 26 lies. A lamp 27 lights up the scale on the stem 2 of a hydrometer floating in the liquid, this hydrometer having a float 22 and a hull including shot agglomerated in a binder and provided with lateral projections preventing rotation of the hydrometer. In another form, Fig. 4, tube 1 includes two electrodes 30, 31 connected in an electric circuit and adapted to give an audible or visible signal when the liquid has been brought into contact with the electrode 30 which is disdisposed at a constant distance from line 6 by movement of a mass 37 in an auxiliary tube 33. A further form is described when the liquid level is brought to a constant distance from the reference plane by a movable mass, the liquid being at this level when the tip of an index carried by tube 1 coincides with the virtual image thereof in the liquid.

Title: Improvements in steam trap and air vent valve therefor
IPC: F16T1/45
Filed: 1953-03-10
Abstract: 724,440. Steam traps. WELLS, H. J. C. March 10, 1953, No. 6593/53. Class 64 (2). A steam trap having a condensate discharge valve 18 also has an air vent valve, e.g. a disc 28 in a casing 21, 23 with an inlet 38 above the water level in the trap and an outlet 31. Moreover, the pressure at the inlet 38 raises the valve disc 28 from concentric, annular seats 22, 25 to permit air discharge, but, when steam escapes, pressure above and below the valve 28 is balanced so that gravity causes closure. A small hole 40 in the valve disc 28 permits dissipation of the steam above the disc so that any inlet pressure may lift it open again. The air vent inlet is fitted with a strainer 24. Steam &c. enters the trap through an inlet 11 and collected condensate lifts the valve 18 by means of a float 14 and a pivoted lever 17 to discharge through an outlet 12 to which the outlet 31 of the air vent valve is connected by a passage 35 in a wall of the trap casing.

[Also in Division C5] A dispersion in oil of an alkaline earth metal carbonate, wherein the diameters of the partides are less than 0À1 micron, is prepared by contacting an alkaline earth metal oxide/ methanol slurry with CO 2  in a countercurrent process for not more than 10 minutes. The carbonated slurry is then intimately mixed with oil containing an oil-soluble anionic dispersing agent and separation of the phases is prevented by agitation before stripping the oil of methanol by distillation. The oil is treated with water at an elevated temperature in order to destroy any remaining complexcontaining methanol, and then is dried and filtered. Before the stripping operation a methanol phase may be allowed to separate and may be removed for recycling. The stripping and subsequent operations are preferably effected in a hydrocarbon solvent, typically a xylene. Reference has been directed by the Comptroller to .Specification 1,053,522.

Title: Improvements in the manufacture of conductive rubber and conductive rubber articles
Inventor: HOARE DONALD ERIC
IPC: C08J3/215
Filed: 1951-03-27
Abstract: Conductive rubber parts are made by mixing an artificial aqueous dispersion or a solution of rubber with an aqueous dispersion of carbon black under such conditions that coagulation of the rubber does not take place, then adding a coagulating agent which is not left in the final composition separating the coagulum, drying it and then extruding it without preliminary mechanical working and vulcanizing the extruded parts.  Naturally occuring rubber latex cannot be used as the aqueous dispersion. The mixture may be coagulated with alcohol, acetic acid or acetone.  In examples (1) 100 parts of smoked sheet, 30 of factice, 10 of mineral oil, 10 of zinc oxide and 3 of sulphur, were soaked in their own weight of commercial rubber solvent, 80 parts of carbon black were dispersed in 7 times its weight of the same solvent and the dispersions mixed and coagulated with industrial spirit, the resulting material being extruded.  (2) An artificial aqueous dispersion was prepared from rubber, potassium stearate, casein, petroleum jelly and dispersing agents and mixed with a dispersion of acetylene black in water.  The whole was coagulated with acetic acid and extruded.
