Title: The manufacture of arsinic acids of the aromatic series
IPC: C07F9/80
Filed: 1924-08-06
Abstract: 2 : 1-Benzoxazolone-4-arsinic acid is prepared by nitrating benzoxazolone, reducing the nitro compound to the amino body, and transforming the latter into the arsinic acid by diazotization followed by treatment with sodium arsenite.  Homologues and derivatives of the arsinic acids are obtained from the corresponding benzoxazolones in the same way.  According to the examples, (1) 4-nitrobenzoxazolone is reduced with iron and acetic acid to 4-aminobenzoxazolone, which on diazotization and treatment with sodium arsenite in soda solution yields a benzoxazolone arsinic acid, which is identical with the compound described in Specification 214,628; (2) treatment of 2-amino-4-methylphenol with phosgene yields 5-methylbenzoxazolone, which on nitration gives 4-nitro-5-methylbenzoxazolone; reduction of the latter with iron and acetic acid produces 4-amino-5-methylbenzoxazolone, from which the methylbenzoxazolone arsinic acid is obtained by diazotization and treatment with sodium arsenite; (3) 2-amino-4-chlorophenol is treated with phosgene and the resulting 5-chlorobenzoxazolone then nitrated; by reduction of the 4-nitro-5-chlorobenzoxazolone produced to 4-amino-5-chlorobenzoxazolone and subsequent treatment of the diazotized amino body with sodium arsenite, the chlorobenzoxazolone arsinic acid is obtained.  The properties of the intermediate products are described.  Azo dyes.-4-Amino-5-chlorobenzoxazolone when diazotized and coupled with resorcinol yields an orange-red dyestuff.

Abstract: 1,037,063. Circuit assemblies. NIPPON ELECTRIC CO. Ltd. May 13, 1963 [May 15, 1962], No. 18872/63. Heading H1R. In a circuit assembly, a first unit assembly comprises a plurality of non-linear circuit elements, such as diodes and transistors, carried on a first base plate and interconnected so as to perform a first circuit function, and a second unit assembly comprises a plurality of linear circuit elements, such as resistors, inductors, capacitors, formed on the surface of a second base plate and interconnected so as to perform a second circuit function. The first and second unit assemblies are interconnected to produce an assembly capable of performing a circuit function of a higher order than said first and second functions. Thus, in one example, diodes connected to form AND gates are mounted on one base plate, further diodes constituting an OR gate are mounted on a second base plate, while a voltage divider is formed by two resistors deposited on a third base plate; the circuits on the three plates are connected serially to a transistor inverter. In a modification, a more elaborate voltage adjusting network is formed on its own base plate, the OR gate and the inverter being replaced by a NOR gate constituted by two transistors mounted on a separate base plate. Other examples include the voltage levelling resistor network 50, Fig. 6 (not shown), which is connected to a further circuit 40 comprising six transistors connected to form two NOR gates with a common input terminal 43. Circuits 40 and 50 may alternatively be interconnected to form a bi-stable circuit. A binary counter made up of a plurality of non- linear and linear elements mounted on separate base plates is also described in the Specification. Construction.-Figs. 9A, 9B, 9C (not shown) depict three rectangular base plates 91a . . . 91c of glass, ceramic, alumina &c. upon which the resistor network 50 is built up. All plates 91a . . . 91c have peripheral grooves 921a . . . 921f, 992a . . . 922f, 923a, 923b, and a corner groove 921g. Conductive areas 57, 58, 93a . . . 93f, 94a . . . 94f, 95a . . . 95f, 96a . . . 96f are deposited on the plates by evaporation of Al, Cu, Ag, Au &c. through a mask. Resistive paths 54a . . . 54f, 55a . . . 55f, 56a . . . 56f, of resistor metal such as Ni alloy or Ag alloy, are evaporated on the plate between appropriate conductive areas. Figs. 10A, 10B, 10C (not shown) depict the plates 91a . . . 91c combined with a fourth plate 97 on which the transistors forming circuit 40 are formed. Connections between the plates are formed by wires located in the peripheral grooves. The plates may be bonded together and encapsulated by an insulating, e.g. plastics, material. The base plates may alternatively be conductive with an insulating coating, and conductive and resistive areas may be applied by electroplating or printing. For the non-linear element groups the surface of the base plate may be covered with semi-conductive material.
