Abstract: 151,646. Szakats, G. March 22, 1917, [Convention date]. Machine g u n s ; cartridge belts.-Relates to means for setting the time fuses of projectiles automatically as the cartridges are fed to the gun chamber, and consists in providing rotary cartridge-feed mechanism and a stationary fuse-setting member, the setting of the fuse ring being effected whilst the cartridge is rotated about a fixed axis into loading position. Fig. 2 shows the invention applied to a machine gun in which the cartridges are carried in clips 33 on a belt 39 which moves over a feed-wheel 36. 38 rotated step by step by the engagement during recoil of a projection 98 on the breech-bolt 20 with inclined grooves 34 in a drum 31. The projectil,es are provided with fluted fuse rings 76, Fig. 3, which are pressed against wedges 38<1> by a spring guide rail 107, whilst the rims 87<1> of the cartridges, Fig. 5, are supported on rollers 37<11> carried by members 37 which are moved radially during the rotation of the feed wheel to press the rims against a fixed toothed sector 106 with which the rims gear to rotate the cartridge. The radial movement is effected by the engagement of rollers 97 on the members 37 in a non-circular groove 35<1> in a disk 35, which disk is adjusted by worm-gear 99 to vary the fuze time or the point relatively to the sector 106 at which the cartridge rim starts to gear with the sector.

Title: Process for the manufacture of isothiocyanate sulphonic acids
IPC: C07C331/16
Filed: 1933-07-22
Abstract: Aromatic and heterocyclic isothiocyanate sulphonic acids are prepared by reacting aminosulphonic acids of the aromatic or heterocyclic series with thiophosgene in an aqueous mineral acid medium.  Thus aminobenzenesulphonic acids, aminonaphthalene-sulphonic acids, aminoazobenzene-sulphonic acids, aminocarbazole-sulphonic acids which may be substituted by halogen, alkyl, alkoxy, hydroxy, or acylamino substituents, may be so treated, advantageously at moderate temperatures and using equimolecular proportions of the reacting components.  A neutrally reacting medium may be initially employed, the hydrochloric acid liberated during reaction then furnishing the mineral acid medium. Compounds containing substituents o- or pto the amino group and which could give rise to side reactions are modified by rendering such substituents inactive; thus a hydroxy group is etherified or an amino group acylated prior to reaction. The products react with primary or secondary amines to give symmetrical or asymmetrical thioureas which can be further converted to ureas or guanidines according to known methods.  Examples illustrate the conversion of the following amino derivatives into the corresponding isothiocyanate derivatives:--2 - amino - 5 - naphthol - 7 - sulphonic acid, 1 - (4<1> - aminobenzoyl) - amino - 8 - oxynaphthalene - 3,6 - disulphonic acid, 1 - [3<1> - 3<11> - aminobenzoyl-)-amino - 4 - methylbenzoyl-] - naphthylamine-3,6,8,-trisulphonic acid, 1-amino-8-(p-toluenesulphonyl)-oxynaphthalene - 3,6-disulphonic acid, 1-naphthylamine-3,6-disulphonic acid, 2-amino-8-naphthol-3,6-disulphonic acid, 4-chloraniline-3-sulphonic acid 2 - (3<1> - aminobenzoyl) - aminobenzene-4-sulphonic acid - 1 - carboxylic acid, 4 - aminophenol - 2 - sulphonic acid, 4 - ethoxyaniline-2-sulphonic acid, 2-anisidine-4-sulphonic acid, 4-aminodiphenylether-2-sulphonic acid, 3-aminophenol-4-sulphonic acid, 1-aminoanthracene-6-sulphonic acid, 2-aminopyridine-5-sulphonic acid, dehydrothiotoluidine-disulphonic acid and monosulphonic acid, the azodye - 1 - amino - 8 - (p-toluenesulphonyl) - oxynaphthalene - 3,6 - disulphonic acid --> 3 - amino - 4 - cresol methyl ether, aminoazobenzene-disulphonic acid, the azo dye sulphanilic acid--> 3-toluidine.

Title: Improvements in magnetic core storage matrices

Filed: 1957-07-01
Abstract: 853,125. Magnetic core data-storage apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. July 1, 1957 [June 30, 1956 (2)], No. 20764/57. Class 106 (1). A magnetic core data storage matrix, Fig. 1, is characterized in that the row-windings and the column-windings each have one driver Tx, Ty respectively, which by means of transistor switches P, one for each row and column, are each caused to pass half-select currents through a selected core. This arrangement is said to be more economical than having one driver stage for each row and column. In the operation of the matrix first the conductive states of the selected two transistor switches are changed from low to high (with no driver current passing) and then the two drivers apply either positive or negative half write pulses depending upon whether reading or writing is desired. In a second embodiment (Fig. 3, not shown) the column and row windings each have two drivers, one for writing and one for reading. Design principles for the transistor switches and for the drivers are discussed in the Specification.

Title: Reference electrodes and measuring systems for detemining the amount of disolved oxygen in a liquid
IPC: G01N17/02
Filed: 1978-05-19
Abstract: The high-temperature reference electrode (10) is used in a measuring device for determining the oxygen content of water at very high temperature. At one end it has a sealed tube (12), preferably made of a palladium-silver alloy. The latter is pressurised with hydrogen from a feed line (18) and is loosely enclosed in a perforated sleeve (14). Through openings (16) in the sleeve, water enters the narrow gap between the tube (12) and the sleeve (14), is retained in the gap and is saturated with hydrogen, which diffuses through the wall of the tube (12). This provides a constant value which serves as a reference level for the measurements of oxygen content carried out together with a measuring electrode. The reference electrode is used in boiler construction, mainly in nuclear reactor boilers. <IMAGE>
