Title: A method and means for determining the moisture content of stationary or moving goods
IPC: G01N27/04
Filed: 1950-11-07
Abstract: 691,332. Electric indicating systems. TRISCHBERGER, K. Nov. 7, 1950 [Nov. 7, 1949; Nov. 2, 1950], No. 27239/50. Class 40 (i). The moisture content of material is measured by drawing air through or from the vicinity of the material and detecting the moisture content of the air by means of a hygroscopic sensitive resistor consisting of spaced metallic conductors mounted on or in a layer of natural or artificial fibre fabric, e.g. cotton, perlon or nylon. As shown for measuring or regulating the moisture content in a moving paper web 1, Fig. 1, a housing 2 resting on the web is provided with ventilation ducts 6 to which suction is applied to cause a continuous flow of air through that portion of the web beneath the housing. This air flow passes through a hygroscopic electrode assembly 9 the resistance of which varies with the moisture content of the air flow and is measured or regulated e.g. by means of a bridge circuit Fig. 5 (not shown). The electrode assembly 9 which is secured to the housing just above the web 1 extends over the whole area thereof and consists of a thin and fine threaded textile web, Fig. 2 e.g. of cotton or nylon in which thin wire electrodes 10 of silver or non-corroding steel are interwoven during manufacture. The electrode assembly may contain hygroscopic material or a conducting salt e.g. copper sulphate pentahydrate, magnesium chloride or calcium chloride. The air flow through the housing may be produced by the ducts 6 alone by providing them with extensions of varying heights, by an exhaust fan, or by convection currents produced by an electric heater 14 in the housing, screened at 15 from the electrode assembly 9. The housing 2 may be enclosed by an outer casing, the space between the two casings being filled with heat insulation to prevent condensation of moisture on the inside of housing 2. Alternatively, the air flow may be produced by drawing air through apertures in the longitudinal .walls of the housing 2, Fig. 7 (not shown).

Title: Improvements in or relating to the manufacture of esters
IPC: C07C69/704
Filed: 1923-10-31
Abstract: Benzyl citrates are produced by benzylating citric acid or salts thereof.  Citric acid may be heated with benzyl alcohol or a citrate treated with a benzyl halide, in the latter case if the salt is dried the action being preferably carried out in presence of a small quantity of an organic base.  In examples an aqueous solution of sodium or potassium citrate is treated with benzyl chloride and the oily product extracted with benzene, the extract dried over magnesium sulphate and the solvent distilled off, the tribenzyl ester being then recrystallized from hot alcohol; dry potassium citrate is treated under a reflux and with agitation with benzyl chloride in presence of pyridine or quinoline, the resulting brown liquor washed with benzene, distilled, rectified and recrystallized to obtain tribenzyl citrate; crystallized citric acid is treated with benzyl alcohol, the liquor drawn off from the crystalline mass which is washed with alcohol to obtain the tribenzyl ester.  The mother-liquor from the last example is distilled to remove benzyl alcohol and the oily residue diluted with water, made alkaline and any remaining neutral ester or benzyl alcohol extracted with ether or benzene. Dibenzyl citrate is precipitated from the aqueous salt solution obtained by addition of sulphuric acid.  The sodium salt of the dibenzyl ester is obtained from its alcoholic solution by neutralization with aqueous soda.  The insoluble calcium, iron and silver salts of dibenzyl citrate may be obtained by precipitation of an aqueous solution of the sodium salt with calcium chloride, ferric chloride and silver nitrate respectively.  A further quantity of tribenzyl citrate may be obtained from the dibenzyl ester by heating with benzyl alcohol.  The esters described above have valuable therapeutic properties.ALSO:Ferric and silver dibenzyl citrates are obtained by precipitation of an aqueous solution of the sodium salt with ferric chloride and silver nitrate respectively.

IPC: H01B1/00
Filed: 1955-10-01
Abstract: <PICT:0815986/III/1> <PICT:0815986/III/2> A support body such as a glass sheet, plate or the like is provided with a transparent electrically conductive film on one surface thereof, and on the other, with a transparent electrically conductive film having a relatively higher resistivity than the first-named film.  The products may be used for aircraft glazings, an electric current being passed through the film of lower resistivity for de-icing purposes, while the film of higher resistivity is used as an external surface for electrostatic dissipation.  In order to permit radio-frequency energy to enter and leave an aircraft canopy, certain areas may be filmed for electrostatic dissipation only.  As shown, a cleaned glass sheet 10 may be suspended by tongs from a carriage running on a monorail 16, and moved into a furnace 17 provided with electrical resistance heaters 18 and baffles 19, where it is heated to substantially its softening point, e.g. for two minutes at 600 DEG C. It is then removed from the furnace and sprayed simultaneously on both surfaces by spray guns 20 and 21 which are mounted on carriages 22, 23 running on rails 24, 25, so that the sprays may be reciprocated.  Preferably equal volumes of air and of spray solution, which may be a solution of stannic chloride in isopropyl alcohol, are used on both sides and the differences in resistivity are obtained either by using different concentrations of the tin salt, to give tin oxide coatings of different thicknesses on the two sides, or by obtaining equal thicknesses by using the same concentration of tin salt, but modifying the resistance obtained on one or both sides by the addition of an iron compound as a conductivity inhibitor.  A small proportion of a gallium compound may be added as a resistivity stabilizer.
