Title: Method and apparatus for increasing seismic signal-to-noise ratio
IPC: G01V1/28
Filed: 1972-06-14
Abstract: 1339530 Seismic signal processing PETTY GEOPHYSICAL ENG CO 14 June 1972 [8 Sept 1971] 27810/72 Heading H4D First and second signals, representative of seismic waves received from a generally horizontal direction and a generally vertical direction respectively, are multiplied together to form a third signal, negative components of the third signal are removed to form a fourth signal, and the fourth signal is multiplied by the second signal to form a fifth signal having a higher signal-to-noise ratio than the second signal. Thus desired compression wave signals from the generally vertical direction are enhanced and undesired non-directional compression wave noise, generally horizontal Rayleigh wave noise and shear wave noise are suppressed. In the embodiments described the first and second signals are obtained from a pair of geophones having their sensitivity axes oriented at a slight inclination to the horizontal and vertical respectively, or from arrays of such geophones. These signals may be recorded in analogue or digital form prior to their multiplication. The fifth signal is formed either by (a) deriving the fourth signal from a half-wave rectifier and multiplying it by the second signal or (b) deriving the fourth signal from a polarity sensor and using it to open a gate circuit for passing the second signal through the gate at instants when the third signal is of positive polarity. The fifth signal is band-pass filtered to remove signal frequencies outside a seismic range of interest.

Patent GB-825507-A (GB)
Title: Improved process for the desizing of glass fibres
IPC: C03C25/002
Filed: 1956-09-13
Abstract: Textile fibres, filaments, strands, yarn, cords roving, matting or woven or knitted fabrics made from glass are desized by treating them for a period not exceeding 30 minutes with a solvent which is either trichlorethylene or perchlorethylene, optionally providing an opportunity for solvent to drain or be expressed or evaporated from them, and then treating them with water held at a temperature of at least 73 DEG  C. in the case of trichlorethylene and at least 86 DEG C. in the case of perchlorethylene until their residual organic content reaches the desired figure.  The solvent is preferably used at its boiling point.  The hot water treatment may be long enough to remove not only the residual solvent but also such constituents of the size as remain unextracted at that point and are water-soluble or degraded or solubilized by hot water, or the hot water treatment may be applied in two stages, the first being carried out in the flash-off chamber where residual solvent is evaporated off and the second in an open vessel where residual constituents of the size are removed.  The process may be combined with other desizing treatments such as heat treatment by passage over a gas-jet singeing machine or an enzyme desizing process, e.g. treatment with an aqueous solution of a malt extract.  The Provisional Specification refers to the desizing of glass and other mineral fibres.

Title: Process for manufacture of intermediates for pigments and dyestuffs
Inventor: CORBY NEVILLE SLATER
IPC: C07D213/74
Filed: 1958-09-04
Abstract: 2,5-Bis-(arylamino)-terephthalic esters are prepared by treating a 3,6-dihydro-2,5-bis-arylamino-terephthalic ester which in one of its tautomeric forms has the formula:  <FORM:0868361/IV (b)/1> where R represents a carboxylic or heterocyclic aromatic residue which may be substituted or which may form part of a polycyclic structure and R1 represents an alkyl group containing up to 5 carbon atoms, with a quinone.  The dehydrogenation may be effected by refluxing a mixture of the reactants in a solvent such as ethyl or amyl alcohol, ethylene glycol; dimethyl formamide or mono or odichlorobenzene.  In a modified form of the process the dehydrogenation is carried out using less than the chemically equivalent amount of the quinone, e.g. 0,01 equivs., and a current of air or oxygen is passed through the reaction mixture. The group R may be a phenyl, naphthyl, pyrenyl, pyridyl, carbazyl or dibenzyfuranyl radical and may be substituted by groups such as chloro, bromo, methyl, ethyl, trifluoromethyl, phenyl, p-tolyl, anilino, acetylamino, benzoylamino, p-toluenesulphonamido, methoxy, ethoxy, b -hydroxyethoxy, phenoxy or cresoxy groups. The reaction is preferably carried out using chloranil but other quinones such as benzoquinone, naphthoquinone, anthraquinone, bromanil, 2,5-dihydroxy-benzoquinone, 2,3-di-cyano-5,6-dichloro-benzoquinone, 2,6-dihydroxy-anthraquinone and acenaphthenequinone, may also be used.  Examples describe the preparation of dimethyl and diethyl esters where the group R is a phenyl, 2,4- and 2,5-dichloropheny, 2-and 4-methoxyphenyl, 4-acetylaminophenyl, 4-phenylaminophenyl, 2-naphthyl and 2-pyridyl radical.  Many other products are specified. 3,6-dihydro-2,5-bis(arylamino) terephthalic esters used in the above examples are prepared by condensing dimethyl or diethyl succino-succinate with the appropriate amine.
