IPC: G01N21/31
Filed: 1968-06-19
Abstract: 1,180,362. Radiation absorption flame analysis. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. June 19, 1968 [June 22, 1967], No. 29242/68. Heading G1A. In a method and apparatus for determining the concentration of an element by introducing it in its vapour state into a flame, and measuring the absorption by the flame of electromagnet radiation of a characteristic wavelength, the flame is burnt in an atmosphere having a pressure less than atmospheric and preferably less than 1 cm of mercury. The burner may be a slit burner and the radiation beam may be passed many times through the flame by a system of confocally arranged mirrors. A pre-mixed or diffusion flame may be used, and the low pressure may be achieved by a vacuum chamber and a pump. A lamp emitting light at the characteristic frequency of a single line may be used, or a lamp emitting a continuous spectrum may be used to simultaneously determine the concentration of a number of elements. Determining the concentration of iron in an iron carbonyl solution in benzene is exemplified.

Abstract: 854,650. Pulse radar; frequency detectors. BENDIX CORPORATION. Sept. 17, 1957 No. 29272/57. Classes 40(5) and 40(7). In a Doppler frequency shift pulse radar system, the successive transmitter and echo pulses of different carrier frequency dependent on velocity of the detected object away from or towards the transmitter are applied, after limiting to equal amplitude, to a frequency discriminator 17, and the D.C. pulse output corresponding to the transmitted pulse applied through a gate 19, operated from the pulse modulator 10, to a storage circuit 20, subsequently its amplitude being compared in a circuit 21 with the D.C. output of same polarity corresponding to the echo pulse; the D.C. difference actuating an indicator 23. The gate output may also be smoothed in a circuit 24 and applied as an automatic frequency control voltage to a local oscillator 14 whose output is best with the transmitted and received pulses to produce an intermediate frequency applied to the discriminator 17. The storage circuit 20 may comprise a cathode follower, diode detector, and cathode follower output. The amplitude comparator 21 may comprise pentode amplifiers for each input, each feeding diode detectors with a common load resistance so that an output /H/ - /G/ is obtained only if /H/ 7 /G/, so avoiding ambiguity. But gain adjustment may be made so that a differential marker pulse appears for zero relative velocity or other datum. The system may also be applied to sonic or ultrasonic detection in air or water.

Title: Process for recovering petroleum
IPC: C09K8/584
Filed: 1963-07-24
Abstract: An emulsion of high thermo dynamic stability used in the recovery of petroleum from underground formations comprises: a non-polar material such as mineral, animal or vegetable oils, ethylene dichloride, dichloroethel, ether, and propylene dichloride; a polar material such as water, methanol, ethylene glycol, ethyl acetate, methyl formate, acetone, methyl ethylketone, formamide, and acetamide; and a surfactant. Isopropanal aids in the stabilization of the emulsion. Suitable surfactants are sodium glyceryl mondaurate sulphate, dihexyl sodium succinate, hexa-decyl-naphthalene sulphonate, diethylenglycol sulphate, glycerol, disulphoacetate monomyristate, p-toluidene sulphate laurate, p-chloroaniline sulphate laurate, sodium sulphate oleylethylanilide, triethanolamine myristate, N-methyl-taurine oleamide, pentaerythrital monostearate, pdyglycerol monolaurate, triethanolamine oleate, morphiodine stearate, hexadecyl trimethylammonium chloride, ditetradecyl dimethyl ammonium chloride, n-dodecyldiethylenoglycal sulphate, monobutylphenyl sodium sulpate and triethanolamine laurate, or polyethylene glycol monolaurates or myristates.  Especially suitable surfactants for petroleum-water emulsions are alkylaryl monosulphonates where the alkyl radical contains 10-20 carbon atoms, and sodium salts of dialkylsuccinates having alkyl radicals containing 6-10 carbon atoms.  Emulsions utilizing chlorinated solvents as the non polar phase use the sodium sulphate derivative of 3,9-diethyltridecanol-6 or the sodium sulphate derivative of 7-ethyl-2-methy-lundecanol-4. 1-hydroxyethyl-2-heptadecenyl glyoxalidine is a suitable agent where the formation water is acidic or contains large amounts of calcium or heavy metal ions. The emulsion is made by dissolving the surfactant in one or both the immiscible materials and then incrementally stirring one material into the other.

Abstract: 983,940. Air cushions &c. AKVAREX A.B. July 24, 1963 [July 26, 1962], No. 29364/63. Heading A4M. Gas filled cushions are manufactured from two or more superposed sheets 16, 17 of thermoplastic resin by sandwiching the sheets 16, 17 between upper and lower die members 10, 11 to form two or more parallel rows of compartments with one or more intermediary conduits 13 therebetween, whereby the peripheral edges of the compartments are sealed except for a small opening which communicates with the conduit 13 through which gas is admitted until the opening is closed by automatic means responsive to the degree of inflation, whereafter welding is effected simultaneously around the entire circumference of each compartment. In one embodiment (Figs. 1, 2), the lower die 11 includes open mould cavities 12 aligned with upper die cavities formed within a mould comprising an inner wall 14 of electrically insulating material and an outer wall 15 of electrically conducting material e.g. brass. A piston 21 comprising an insulating portion 22 and a conducting portion 23 is held by a guide 24 in a recess in the outer mould wall 15 and is slidably moved in the recess by means of a vane 18, pivoted at 19, which vane 18 is lifted by the upper sheet 17 when the container is inflated. In operation, the sheets 16, 17 are firmly gripped between the dies 10, 11 and gas is admitted via an inlet 27 and the conduit 13 between the sheets 16, 17 in the region of a cut-away portion 25 in the inner mould wall 14. Lifting of the vane 18 causes a lowering of the piston 21 until it contacts the upper sheet 17 and seals the opening 25 whereafter, high frequency current is supplied to the outer wall 15 and to the conducting portion 23 of the piston 21 to weld around the circumference of each compartment. In another embodiment (Figs. 5, 7) a slide 29 is mounted between the two parts of a brass plate 28 secured to the upper die 10, which slide carries studs 30 each having an oblique surface 31 engaging a corresponding surface on the piston 21 which carries a pin engaged in a slot 34 in the guide 24 and is urged by a spring 35 into contact with the stud 30. In operation, inflation of the compartment causes the upper sheet to contact and move a rod 45 to actuate a micro-switch 44 thereby to cause a pneumatic or hydraulic cylinder 39 to swing a pivoted lever 40 and hence move the slide 29 which depresses the piston 21 to close the opening 25 and simultaneously to shut off the gas supply by operation of a valve 43, whereafter the circumference of each compartment is welded.
