Title: Improvements in or relating to the treatment of iron or zinc, or of alloys of either iron or zinc, for the production thereon of phosphate coatings
IPC: C23C22/73
Filed: 1938-12-20
Abstract: 522,954. Cleaning and coating metals. AMERICAN CHEMICAL PAINT CO. Dec. 20, 1938, No. 37069. Convention date, May 27. [Class 82 (ii)] [Also in Group XXXVI] To produce a phosphate coating on a surface of iron, zinc, or alloys thereof the surface is treated with an acid aqueous solution containing oxalic acid and then, without any intermediate mechanical treatment such as wiping or brushing, is subjected to the action of a phosphate coating solution. Before treatment with the oxalic acid solution the surface may be, cleaned, e.g. by ' pickling, vapour degreasing, alkali cleaning &c. The oxalic acid solution may contain other substances, e.g., sulphuric, nitric, hydrochloric, acetic, or pnosphoric acids, salts such as sodium or potassium nitrate, phosphate, sulphate, chloride, or acetate, organic substances such as alcohols, ethers, acetone &c. wetting agents such as isopropyl naphthalene sulphonic acid, and corrosion inhibitors such as coal ' tar bases, thioureas, sulphite pulp waste liquor, or aldehyde-amine condensation products. If the surface has been subjected to a strong alkakli cleaning, mineral acids are preferably added to the oxalic acid solution. The action of the solution may be accelerated by the presence of copper or silver in solution, e.g., by-addition of copper sulphate, chloride, carbonate, or oxide.'The duration of treatment in the oxalic acid solution is preferably sufficient to etch the surface but not sufficient to produce an oxalate coating, the duration depending on the concentration, the temperature, and the rate of relative, motion between the surface and the solution. The treated surface may be rinsed, and, if desired, dried before it is subjected to the action of the phosphate solution. The, phosphate coating solution is preferably one comprising mainly zinc or manganese phophates used at a temperature below boiling, e.g. 100 - 200F.; its action may be accelerated by addition of oxidizing agents or metals such as copper, cobalt or nickel, by violent impingement on the surface to be coated, or by making the piece to be coated an electrode and passing alternating current through the solution. Pretreating solutions -specifically described are solutions of oxalic acid alone, of oxalic acid and copper sulphate, and of oxalic acid, phosphoric acid, butyl alcohol, and denatured alcohol, the last solution being used both for cleaning and etching. Specified phosphatizing baths are made by dissolving (1) zinc oxide and phosphoric acid, (2) manganese carbonate, phosphoric acid, sodium nitrate, and cupric nitrate, and (3) zinc oxide, nickel carbonate, phosphoric acid, and nitric acid. The phosphatized surface may be coated with paint, varnish, lacquer, japan &c.

Title: Method and apparatus for radioactive well logging
IPC: G01V5/10
Filed: 1973-08-07
Abstract: 1396255 Borehole logging MOBIL OIL CORP 7 Aug 1973 37333/73 Heading G1A In a method of logging a well of the kind in which the subterranean formation around the borehole is irradiated with a burst of fast neutrons which are slowed to a lower energy neutron population, the decay of the lower energy population is measured by measuring the radiation associated with it over two time intervals, the second time interval starting during the first one and ending after it. This overlap of intervals allows each to be longer than in standard non- overlapping methods using the same total measuring time, so that the accuracy of measurement is increased. Fig. 1 shows a logging tool 10 in the borehole. A motor 34 drives an apertured plate 32 so as to cyclically expose targets 28 to radiation from alpha emitters 29; on exposure the targets emit fast neutrons into the surroundings. An accelerator type of source may be used. Thermal neutrons or gamma rays produced as the fast neutrons are slowed are detected at 27, e.g. by one or more He<SP>3</SP> detectors. The detector output and a synchronizing signal from a transducer 35 associated with the motor drive, as passed along cable 12 to the circuitry of Fig. 3 where they are analyzed and plotted against a depth signal from wheel 24 of Fig. 1. The detector signal is amplified at 40, Fig. 2, and applied to a threshold device 42 which gives a pulse every time the detector signal shows a neutron has been received. The pulse is delivered to channels 44, 45 and 46; the latter has a counter 64 connected to recorder 22 so that the porosity of the formation can be recorded, the counter output being mainly affected by the slowing of the fast neutrons by hydrogen nuclei and these nuclei being a measure of porosity. The other two channels each comprise in series a gate, a counter, a subtractor and a logarithmic circuit. In channel 44 the gate 48 is opened during the first time interval by circuit 54 in response to the synchronizing signal, and in channel 45 gate 49 is similarly opened during the second interval. After counting the two channel signals pass to subtractors 68 and 70 respectively where a signal from the third channel representing background radiation is subtracted, then after being converted to logarithms at 72, 74 the signals are subtracted at 76. The resulting signal is then multiplied at 78 by the reciprocal of the product of the thermal neutron velocity and the time between the start of the two intervals to give a final output to recorder 22 representing the macroscopic neutron capture crosssection of the formation.

Title: Gelled compositions
Inventor: TAYLOR MICHAEL JOHN
IPC: C09D7/00
Filed: 1963-09-24
Abstract: A clay capable of base exchange and of swelling in water is treated in the aqueous phase with an ammonium compound to give a modified clay, there being used from 40 to 500 (preferably from 100 to 300) milliequivalents of ammonium compound per 100 grams of clay. Clays which are suitable for the treatment are naturally-occurring clays containing high proportions of montmorillonite, for example Wyoming bentonite, hectorite and other bentonites, which clays may be activated, for example by soda ash, to replace cations other than sodium ions, for example calcium ions, by sodium ions thereby to enhance the ability to swell in water.  The ammonium compound has a cation of the general formula R1R2R3R4N+ wherein R1 is a substituted or unsubstituted lower alkyl group and R2, R3 and R4 are hydroge atoms or substituted or unsubstituted lower alkyl groups, the lower alkyl groups being the same or different and each containing from one to four carbon atoms, or wherein R1R2 represent not more than four carbon atoms in a cyclic saturated group containing the ammonium nitrogen atom and R3 and R4 are as defined above, the total number of carbon atoms in R1, R2, R3 and R4 in either of the above alternatives not exceeding six. The lower alkyl groups, examples of which are methyl, ethyl, propyl, n-butyl and isobutyl groups, may be substituted with, for example, amino or hydroxyl groups (which groups themselves may be substituted) or halogen atoms.  The anion of the ammonium compound may be the chloride, bromide, iodide, formate, acetate, nitrate, sulphate or hydroxyl ion.  The ammonium compound may be a salt formed from methylamine, dimethylamine, trimethylamine, tetramethyl ammonium hydroxide, ethylamine, diethylamine, triethylamine, n- or isopropylamine, n-, sec-, tert- or iso-butylamine, ethanolamine, diethanolamine, triethanolamine, 2 - aminoethylethanolamine, methyldiethanolamine, N,N - dimethylaminoethanol, isopropanolamine, di - isopropanolamine, 2 - amino - 2 - ethylpropane - 1,3 - diol, 3-dimethylaminopropane - 1 - ol, 1 - dimethylaminopropane - 2 - ol, 2 - amino - 1 - butanol, ethylenediamine, 1,2 - propylenediamine or morpholine.  A gelled aqueous composition, in which is dispersed from 1.5 to 20 (preferably from 2 to 6) per cent by weight, based on the aqueous content of the composition, of clay modified with an ammonium compound as defined above, may be prepared by dispersing unmodified clay in the aqueous composition which is to be gelled and then adding thereto either the ammonium compound or, separately and preferably in equivalent amounts, a base and an acid which together form the ammonium compound, for example as an aqueous solution or solutions.  The gelled aqueous composition should have a yield value (the minimum force which must be applied to the gel to cause it to flow) greater than 20 dynes per square centimetre.
