Abstract: 1,048,857. Geophysical prospecting. TEXACO DEVELOPMENT CORPORATION. June 1, 1965 [June 2, 1964], No. 23397/65. Heading H4D. In a seismic signal processing system, electrical signals from a geophone or reproduced field record are applied to a plurality of parallel signal channels each containing a band-pass filter passing a different frequency band, the outputs of the filters being combined in timevarying proportions by means of a potentiometer network and fed to a recording device. In the embodiment of Fig. 7, ganged potentiometers 51, 52, 53, whose wipers may be driven from the motor drive of the recording device, determine the time-varying proportions in which the outputs of filters 46, 47, 48 are combined on a summing resistor 76. Thus high frequency components of the seismic signal may be emphasized in the first portion of the seismic record, intermediate emphasis may be given to both high and low frequency components during the middle portion of the record, and low frequency components may be emphasized in the end portion of the record, corresponding to increased attenuation of high frequency components with travel-time of the seismic waves in the earth. The law of variation of resistance along a potentiometer track may be linear, logarithmic, or modified as required by shunting taps on the potentiometer. Further adjustment of the signal combination proportions may be obtained using potentiometers 61 to 66. Other embodiments are described (Figs. 2, 3, 8, none shown) whch have alternative potentiometer interconnections between the signal channels, further adjustment of the signal combination proportions in the Fig. 3 and Fig. 8 embodiments being obtained by connecting the filter outputs to switched taps on a potentiometer.

The invention comprises 10-cyano-17a-ethynyl-19-nor-#<SP>5</SP>-androstenes of the formula wherein X is the group in which R is hydrogen or a lower alkyl radical having 1-3 carbon atoms and n is 1 or 2 and in a process for preparing 17α-ethynyl-19-nor steroids the step which comprises denitrilating a 10 - cyano - 17α - ethynyl - 19 - nor - #<SP>5</SP> - androstene of the formula wherein X and R are as defined above, with an alkali metal in ammonia or an alkali metal amide, in the absence of any alcohol reagent and in the presence of a non-alcoholic organic solvent to produce a mixture of #<SP>5(6) </SP>and #<SP>5(10)</SP>isomers of the corresponding 17α-ethynyl- 19-nor-androstene derivative. Hydrolysis of a mixture of #<SP>5(6)</SP> and #<SP>5(10)</SP> isomers of 17α- ethynyl - 19 - nor - androstene - 17# - ol - 3 - one 3-ethylene ketal with dilute mineral acid or alkali yields 17α - ethynyl - 19 - nortestosterone. Alternatively treating said mixture of isomers with the anhydride of an alkanoic acid containing up to 7 carbon atoms in the presence of an acid catalyst and treating the resulting 3,17#- diacyloxy - 17α - ethynyl - 19 - nor - #<SP>3,5</SP> - androstadiene with an alcohol of the formula R<SP>1</SP>OH wherein R<SP>1</SP> is an aliphatic hydrocarbon radical having 1-10 carbon atoms, in the presence of an acid catalyst, yields a 3-enol ether of 17α- ethynyl - 19 - nortestosterone ester. 10- Cyano - 17α - ethynyl - 19 - nor - #<SP>5</SP> - androstene-3-one 3 alkylene ketal is obtained by (a) oxidizing 10 - cyano - 19 - nor - #<SP>5</SP> - androstene-3#,17#-diol to form the corresponding 3- hydroxy - 17 - keto compound, treating the latter with an alkaline acetylide to form 10- cyano - 17α - ethynyl - 19 - nor - #<SP>5</SP> - androstene- 3#,17# - diol, which is oxidized and ketalized consecutively in 3-position; (b) oxidizing 10- cyano - 19 - nor - #<SP>5</SP> - androstene - 3#,17# diol to form the corresponding 3,17-dione, which is ketalized in 3-position and treated with alkaline acetylide. 10-Cyano-19-nor-#<SP>5</SP>-androsten-3#, 17#-diol is obtained by reducing 3#,17#-diacetoxv - 5α - androstane - 6 - one to form 5α- androstane - 3#,6#,17# - triol, nitrosylating the latter in 6-position and irradiating to obtain 19 - oximino - 5α - androstane - 3#,6#,17# - triol- 3,17-diacetate, which is treated with phosphorus oxychloride to obtain 10.cyano.19-nor. 5-androstene-3#,17#-diol.

Abstract: 1,054,797. Printed circuits. NORTH AMERICAN AVIATION Inc. Sept. 12, 1963 [Sept. 24, 1962], No. 36017/63. Heading H1R. A multilayer printed circuit board having internal interconnections between printed wiring at different levels is made thus, starting with an insulating substrate 12 of epoxy resin impregnated glass cloth clad on both sides with copper sheets 10, 11. Holes 16<SP>1</SP> ... 19<SP>1</SP> are formed in copper sheet 11 by a photo-etch process using FeCl 3  solution as etchant; then registering holes 1611, 17<SP>11</SP> &c. are etched in substrate 12 using an etchant composed of a solution of H 2 SO 4  and HF. The walls of the holes and the exposed surfaces of sheets 10, 11 are electroless-plated with Cu, which coating is oxidized and then reduced with formaldehyde solution to form a rough surface on the walls of the holes; the Cu coating is removed from sheet 11, as by abrading. Next the whole is electroplated with Cu; then the holes are filled with conductive material to connect plates 10 and 11 together. The conductive filler may be a mixture of Cu, Ag, or Au and resin, or an alloy of Ga, In, Hg &c. with Cu, Au, Ag, &c. A preferred filler comprises a eutectic of Ga and In mixed with Au, and may be applied to the holes by squeezing in the plastic state; alternatively, equal weights of powdered In and Au are placed in the holes and heated to alloy; or a sphere of a mixture of powdered metals such as Au, Pb and Sn is placed over each hole and heated. Preferably the assembly is again electroplated with Cu. A wiring pattern is formed in Cu sheet 11 by photo-etching; if desired a pattern may be formed in sheet 10 simultaneously or subsequently. A further sheet of insulating material clad with a third conductive sheet is laminated over the pattern formed in sheet 11 and the process is repeated; and so on, for all subsequent layers.

The electrolyte in an electrolytic capacitor consists of sodium formate dissolved in from 5 to 70% by weight ethylene glycol monomethyl ether and 30 to 95% of a compatible solvent, e.g. dimethyl formamide, propylene carbonate, gamma butyrolactone, ethylene glycol and diethylene glycol. In the case of aluminium electrodes, the tolerable water content is less than 1%.
