Title: Substituted ammonium humate and process of making same
IPC: C08H99/00
Filed: 1962-03-09
Abstract: The invention comprises substituted ammonium humates of the formula R1R2R3R4N+ Hu-, wherein Huis the anion of humic acid, at least one of the R's is an alkyl or alkenyl radical having from 12 to 22 carbon atoms in a straight chain and those R's which do not have 12 to 22 carbon atoms in a straight chain represent hydrogen, alkyl radicals having fewer than 12 carbon atoms, phenyl or benzyl, or two of the R's form a carbon ring including N heterocyclically and bearing said 12 to 22 carbon atom alkyl or alkenyl radical, and wherein when two of the R's form a nitrogen-containing heterocyclic ring one of the remaining R's additionally may be hydroxyalkyl or phenyl-substituted hydroxyalkyl. They may be prepared by causing an appropriate ammonium ion of the formula R1R2R3R4N+ to react wit a humate ion, for example by reacting an alkyl ammonium compound in its basic form with humic acid or by reacting the alkyl ammonium compound in its salt form with an alkali salt of humic acid.  Quaternary substituted ammonium salts or hydroxides may be reacted directly with humic acid, preferably in the presence of a base.  The examples illustrate the preparation of dimethyldioctadecyl-, lauryl-and dimethyldi (hydrogenated tallow alkyl)-ammonium humate using sodium humate obtained from lignite.ALSO:Well-working fluids comprise an oily liquid and a substituted ammonium humate of the general formula R1 R2R3R4N+Hu-, wherein Huis the anion of humic acid, at least one of the R's is an alkyl or alkenyl radical having from 12 to 22 carbon atoms in a straight chain and those R's which do not have 12 to 22 carbon atoms in a straight chain represent hydrogen, alkyl radicals having fewer than 12 carbon atoms, phenyl or benzyl, or two of the R's from a carbon ring including N heterocyclically and bearing said 12 to 22 carbon atoms alkyl or alkenyl radical, and wherein when two of the R's form a nitrogen-containing heterocyclic ring one of the remaining R's additionally may be hydroxyalkyl or phenyl-substituted hydroxyalkyl. The oily liquid is most desirably diesel oil but may be any available crude oil, topped or untopped, or various fractions of crude oil, e.g. kerosene and fuel oil.  Generally 2 to 50 lbs. of humate are added per barrel of well-working fluid. Said fluid may also contain weighting materials, e.g. finely ground clay, limestone, silica, barite and celestite; propping agents, e.g. sand, aluminium spheres and walnut shells; thickening agents, e.g. asphalts and soaps; and 1 to 30% by volume of water. In the examples well-working fluids are produced from diesel oil and dimethyldioctadecylammonium humate (Example 4) and diesel oil, dimethyl-(hydrogenated tallow alkyl) ammonium humate, sulphurized tall oil, caustic soda and calcium chloride (Example 8).

Abstract: 493,285. Treating charge ; vaporizers. MARTINI, P. March 31, 1937, No. 9229. Convention date, Dec. 2, 1936. [Classes 7 (ii) and 7 (iii)] Condensation of liquid fuel in induction pipes is prevented by passing a preformed mixture of air and finely divided fuel through or over a mass of gravel, quartz, glass, or baked earth, the temperature being kept at less than 80‹ C. Gravels from the following valleys of the Italian Alps are preferred : Val Lurisia, Stura, Gesso, or Grana ; but a synthetic gravel made by burning, or roasting, an intimate mixture of the constituents may be used. Primary air, controlled by a valve 5 and heated in a chamber 3 by exhaust gas, passes through a gauze cone 8, radiating from the centre of which are small tubes which deliver fine jets of fuel on to the inner surface, and thus form a rich mixture. The gravel, quartz, glass or baked earth, in the form of small pieces, a powder, or porous slabs, is placed in a chamber 10, and, preferably, also in a second chamber 13 which receives secondary air, heated or not, through a valve-controlled pipe 15.

Title: Ultrasonic flaw detection apparatus
Inventor: ALDRIDGE-COX DOUGLAS
IPC: G01N29/44
Filed: 1967-03-01
Abstract: 1,224,312. Recording peak voltages. S.T.D SERVICES Ltd. Feb.28, 1968 [March 1, 1967], No. 9691/67. Heading G1U. In a system for recording electrical signals produced by an ultra-sonic flaw detector, a number e.g. two, of peak reading stores are connected sequentially by a sequence control system to the signal source and subsequently to a direct writing recorder, so that only the largest flaw signal originating from the detector during the period that each particular peak reading store is connected to it is recorded. The control system incorporates a counter 34 energized by a pulse generator 35 and providing outputs to bi-stable circuits 37, 38. The bi-stable circuits produce outputs so as to alternately open the AND gates 12 and 13 and the AND gates 16, 17 in anti-phase, and also to provide reset pulses to the peak reading stores 14, 15 at appropriate times. The pulse generator 35 may also control the operation of the detector 11. The system operates so that while one peak reading store charges to the maximum signal occuring in a given period, the other is read out for the preceding period and reset. The individual peak reading stores, Fig.2 each incorporate a capacitor 20 which is charged when connected to the detector via transistor 23 and diode 22. The voltage across the capacitor is detected by the field effect transistor 26, the voltage across a load 27 in the source-drain circuit of this being used as the output. The capacitor is reset or discharged, by applying a pulse to switch on the transistor 30 to provide a short circuit across the capacitor through the diode 29.

Abstract: PURPOSE:To compare many voltages sequentially with a small number of elements by performing input control so that while one active element for negative input operates, other active elements for negative input are equivalently absent in consideration of a circuit. CONSTITUTION:The circuit consists of N channel MOS enhancement type transistors (NTR)107-110 and P channel MOS enhancement type transistors (PTR)101-106 and the inputs of the PTRs 104 and 106 are denoted as -A and +. Here, when the potential at a terminal 115 is applied to the -A, the PTR104 is cut off and becomes absent in consideration of the circuit. Here, this circuit becomes a circuit which compares the voltages at -B and + with each other. When the potential at the terminal 115 is applied to the -B, on the other hand, the PTR105 is cut off and becomes absent in consideration of the circuit and the voltages at the -A and + are compared with each other. Thus, many voltages are compared sequentially with a small number of elements.
