Title: Manufacture of new alkylaniline monosulphonic acids
IPC: C07C309/31
Filed: 1936-01-17
Abstract: Substituted anilinesulphonic acids are obtained by sulphonating C-alkylanilines containing 6--18 carbon atoms in the alkyl group or their nuclearly chlorinated, brominated or methylated derivatives. The starting materials are obtainable (1) by heating aniline or its nuclearly chlorinated, brominated or methylated derivatives, or the hydrochlorides or hydrobromides of any of these, with a saturated primary aliphatic alcohol of 6--18 carbon atoms and a halide of cobalt or zinc, or (2) by heating N-alkylanilines containing 6--18 carbon atoms in the alkyl group, or their nuclearly chlorinated, brominated or methylated derivatives, or the hydrochlorides or hydrobromides of any of these, with a halide of cobalt or zinc in the presence or absence of the hydrochloride or hydrobromide of the parent aniline. Alcohols specified for use in preparing the starting materials are hexyl, octyl, decyl, dodecyl, tetradecyl, hexadecyl and octadecyl alcohols, and these may be pure or crude products; thus, use may be made of crude hexadecyl alcohol obtained by saponifying spermaceti, or of crude dodecyl and tetradecyl alcohols (lorol) obtained by reducing the fatty acids from coconut oil.  The preparation of suitable starting materials is described in Specification 468,226.  In the examples: (1) p-dodecylaniline is sulphonated with fuming sulphuric acid to yield 4-dodecylaniline-3-sulphonic acid; the constitution of the product is established by its behaviour on bromination, a dibromosulphonic acid being obtained; p-dodecyl-o-toluidine may be similarly sulphonated; (2) p-dodecylaniline is sulphonated with chlorsulphonic acid to yield 4-dodecylaniline-2-sulphonic acid; the constitution of the product is established by its behaviour on bromination, a dibromo compound being obtained with elimination of the sulphonic group; p-dodecyl-o-toluidine may be similarly sulphonated; (3) p-decylaniline and (example 4) p-tetradecylaniline are sulphonated as in example 2 to yield 4-decyl- and 4-tetradecyl-aniline-2-sulphonic acids; (5) and (6) p-hexadecylaniline is sulphonated as in examples 1 and 2 to yield 4-hexadecylaniline-3- and -2-sulphonic acids.

Title: Improvements in or relating to strip chart recording apparatus
Inventor: HORABIN IVAN SAMUEL
IPC: G01D9/16
Filed: 1961-01-16
Abstract: 927,566. Recording-apparatus. MARRYAT & PLACE Ltd. Jan. 11, 1962 [Jan. 16, 1961; April 10, 1961], Nos. 1786/61 and 12876/61. Class 106 (4). Apparatus for recording a variable signal voltage s on a travelling strip graduated across its width for a full-scale value v comprises a uniselector switch UN2 with banks W, X for reversing the polarity of the signal each time the voltage s reaches or increases beyond a multiple of v, a bank V of contacts ganged in pairs 1, 2; 3, 4 . . . for alternately introducing and maintaining successively modifying voltages of 2v, 4v . . . in opposition to the signal voltage s and banks Y, Z for reversing the polarity of the modifying voltage each time the polarity of the signal is reversed and a switching system for reversing the stepping of the uniselector UN2 following a change from increasing to decreasing values of the signal s and vice versa. Microswitches MS1, MS2 on the zero side of the record strip and MS3, MS4 on the full scale side are closed by the pen arm each time it reaches the zero or full scale position. When s increases to 2v switch MS1 completes a circuit through bank B of another uniselector UN1 and one of two windings of the coil of uniselector UN2 to move its wipers forward one step. At the same time switch MS2 closes a circuit through the coil of uniselector UN1 opening SW1 but being held through bank C until the pen arm opens switch MS2 and de-energizes the coil of switch UN1 to advance its wipers a step. This reverses the connections to the coil of switch UN2 so that if the pen arm reaches switch MS3 the same winding will again step its wipers forward. If, instead of increasing to 2v, s had decreased to v switch MS3 would have completed a circuit through bank A and the other winding of the coil of uniselector UN2 to move its wipers back a step. In this way a peak value many times the fullscale value may be recorded and a visual indication may be furnished of the number of fullscale deflections traversed by the pen arm in recording the peak. An alternative switching system, Fig. 2 (not shown), is described whereby the pen arm controls the switch UN2.

Abstract: 940,520. Semi-conductor devices. GENERAL ELECTRIC CO. Jan. 19, 1962 [Jan. 23, 1961], No. 2019/62. Heading H1K. A tunnel diode comprises a heavily impregnated body 1, Fig. 3, having at one of its surfaces a small regrown area 2, has a layer of dielectric material 6 surrounding the regrown area, and a continuous metallic layer 7 deposited on the dielectric material and having electrical contact with the regrown area. As shown, the body 1 of N-type material such as germanium heavily doped with phosphorus is alloyed with a pellet 4 consisting of indium containing 2% gallium to form a P-N junction 5. A metallic base layer 8 is then deposited on the surface, using a mask to prevent this layer from contacting the regrown region. The dielectric layer is then deposited over the whole of the area surrounding the pellet 4 and the metallic layer 7 is then deposited over the whole area to contact the pellet 4. External contacts are established via the layer 7 and either the layer 8 or the body 1. In a modification, Fig. 6, the surface of the body 13 is provided with a thin higher purity layer of germanium by " outdiffusion " or epitaxial growth and then etched to provide a mesa 15 of high resistance material. Alloying and deposition of the various layers then takes place as before. This method eases the stringency otherwise necessary in accurately depositing the layer 8. In this case the metal 8 may be aluminium or tantalum and the dielectric may be formed by oxidation, e.g. by heating in oxygen or air or by electrolytic anodization. In other embodiments suitable metals for layers 7 and 8 are silver, gold, aluminium, indium, tin, platinum and tantalum and suitable dielectric materials may be manganese or magnesium fluoride, silicon monoxide or dioxide, zinc sulphide, cryolite, aluminium oxide or polystyrene. Other semi-conductor materials may be silicon, silicon carbide, Group III-V compounds, Group II-VI compounds or lead sulphide. A method of making the device utilizing vapour deposition for the various layers with the use of appropriate masks is outlined. Specification 914,832 is referred to.
