Title: Method and device for determining the depth of a magnetic anomaly
IPC: G01R33/022
Filed: 1972-06-12
Abstract: 1351912 Magnetic surveying COMMISSARIAT A L'ENERGIE ATOMIQUE 12 June 1972 [16 June 1971] 27287/72 Heading G1N In aerial magnetic survey, the depth Zo of a submerged magnetic anomaly at least approximately comparable with a horizontal dipole (e.g. a submarine) is deduced by determining the variation in the perturbation H to the Earth's magnetic field caused by the anomaly and the variation in the gradient -#H/#u a long a horizontal path perpendicular or parallel to the dipole and calculating Zo using the formula where m = 1 if the path is parallel to the dipole or 1/3À5 if perpendicular. The path may be a circle centred at the origin of the anomaly or in the form of a fourleaved clover crossing the origin in directions parallel and perpendicular to the dipole. In Fig. 5, the output of a frequency meter 18 connected to a proton resonance magnetometer head 10 mounted in a tail extension of an aircraft is corrected for magnetic effects of the aircraft by subtracting at 20 the output of a phase meter 16 connected to a proton resonance filter 12. A bandpass filter 22 eliminates the constant components of the field so that only the perturbation H is recorded on a tape recorder 24. The output of filter 22 is sampled at 27 at regular intervals (e.g. 1 second) determined by a clock 30 and fed to a shift register 28. H max is determined by a comparison circuit 32 and (#H/#u) max is determined by a subtractor 34 and comparison circuit 36. Circuit 38 calculates Zo, using a manually set value of m. The aircraft's altitude may be fed in at 44 to be subtracted from Zo.

Title: Process for the production of cellulose nitrate from regenerated cellulose
IPC: C08B5/02
Filed: 1937-10-12
Abstract: Regenerated cellulose sheet material which has been softened with glycerine or similar softener and coated with a lacquer or varnish, is treated with a nitrating acid such as a mixture of p  concentrated nitric and sulphuric acids to form cellulose nitrate with or without admixture with nitroglycerine.  The regenerated cellulose sheet material may be shredded, before nitration, into pieces having an area of about 2-12 square inches and after nitration the product may be freed from particles of detached coating material by flotation, quenched in water and then stabilized.  The stabilization is effected by first giving the material several hot and cold water washes, then boiling with water for several hours, crushing the material to particles, boiling with water for several hours again and finally giving the material several more hot and cold water washes.  By carrying out the nitration at temperatures above 30 DEG  C., pure nitrocellulose of low viscosity may be obtained, but by using a coated regenerated cellulose material that has been softened with glycerine and carrying out the nitration below 30 DEG  C., a mixture of nitrocellulose and nitroglycerine suitable for explosives may be obtained.  In the latter case, the treatment with nitrating acid may take place initially at a temperature above 30 DEG  C. in order to attack the coating material, the temperature being subsequently reduced to below 30 DEG  C.  According to the Provisional Specification, uncoated regenerated cellulose sheet material may be nitrated or the coating of coated regenerated cellulose sheet material may be destroyed and removed by other reagents than the nitrating acid.  U.S.A. Specification 1,997,766 is referred to.

Title: Recovery of absorbable substances from gaseous mixtures
IPC: B01D53/04
Filed: 1927-10-22
Abstract: 291,277. Marks, E. C. R., (Carbide & Carbon Chemicals Corporation). Oct. 22, 1927. Gases, separating mixtures of. - In the recovery of vapours such as ether, alcohol, &c. from mixtures with incondemible gases such as air by absorption in solid or liquid absorbent from which the vapour is subsequently expelled by heating, the incondensible gases are removed from the system before regeneration of the absorbent commences. For example, steam may be passed through the vacant spaces of the apparatus (but not through the absorbent, itself) in order to displace the gases, which may be then passed into another absorber for the recovery of their valuable contents. After the removal of the permanent gases steam may be passed through the absorbent to drive out the absorbed vapours, and in the case of materials miscible with water these may be recovered by rectifying the resulting mixture with the aid of the latent ú heat of the steam contained therein. The figure illustrates a system with two absorbers A, A<1> in alternate use. The gas mixture is forced by the blower F via the valve 2 into the absorber A<1> through which it passes downwardly, escaping through the valve 4 and outlet 20. When this absorber is fully charged the gas mixture is diverted to the other absorber. Steam is then admitted at 18 and passes through the upper and lower spaces of A' in series via the valves 8, 10, 12, and 13, displacing the permanent gases and returning them to the mixture passing through A. Subsequently valves 10 and 13 are closed and the steam now traverses the absorbent layer B driving out the absorbed vapours. The mixture is passed through valve 14 to a coil S in the base of a rectifying column R into which the mixture subsequently passes. Water condenses and is drawn off at 21 while the more volatile substancgs (e.g. alcohol and ether) are drawn off at appropriate points 22, 19 in the rectifier or in a subsequent condenser C.

Abstract: 1,098,979. Transistor amplifiers. MARCONI CO. Ltd. March 1, 1966 [July 3, 1965], No. @8260/65. Heading H3T. A transistor amplifier, for use at high frequencies, includes two transistors T1, T2 connected in cascode with the emitter-collector connection of the transistors connected through a capacitor K to a point, preferably earth, common to both the input and output circuits of the amplifier. Capacitor K is dimensioned such that its reactance, together with that of the output impedance of transistor T1, is less than half the minimum reactance of the other transistor when its output is short-circuited. The capacitor is said to suppress oscillations which would otherwise occur owing to transistor T2 acting as a generator, such oscillations being particularly prevalent at the high frequencies and in the micro-miniaturization applications for which the circuit may be used.
