Title: Preparation of amides of nitrogen heterocyclic compounds
IPC: C07D213/81
Filed: 1970-11-19
Abstract: 1327627 Heterocyclic amides MONTECATINI EDISON SpA 19 Nov 1970 [21 Nov 1969] 55122/70 Heading C2C Heterocyclic amides in which the carbonyl group is directly attached to a carbon atom of an aromatic heterocyclic ring containing at least one nitrogen atom in a 5- or 6-membered ring, are obtained by reacting the hetero-aromatic base with a formamide HCONR 2 , where R 2  is hydrogen or C 1-5  alkyl, and with a free radical R<SP>1</SP>O, where R<SP>1</SP> is hydrogen, alkyl or cycloalkyl. The free radicals may be generated by thermal decomposition, e.g. at 110-140 C., of a dialkyl peroxide R<SP>1</SP>-O-O-R<SP>1</SP> or in a redox system consisting of the hydroperoxide R<SP>1</SP>-O-O-H and ferrous ions operating at -10 to 60 C. Preferred amide reactants are formamide and dimethylformamide which may be used in excess, optionally with water, to provide a solvent. Specified bases are pyridine, alkylpyridines, quinoline, alkylquinolines, isoquinoline, pyrazine, quinoxaline pyrimidine, benzimidazole and benzothiazole which may contain other substituents, e.g., amino. Mono- and poly-amides may be obtained depending on the reactant ratios. Substitution normally occurs ortho- or parato the ring nitrogen atom.

Abstract: 1387197 Guillotine cutting machines SIMONVK Ltd 3 Dec 1973 [1 Dec 1972] 55479/72 Heading B4B A guillotine machine comprises an elongated backgauge 1 for moving the material towards a cutting station X-X, the backgauge being connected to an endless drive member, e.g. a chain 8 driven by means of, e.g. piston-and-cylinder device 11, 12 such that when the drive member is moved by the drive means the backgauge moves in a rectilinear path in a direction at right angles to its longitudinal axis. The piston-andcylinder device is connected to a pair of doubleacting solenoid-operated valves 14, 16 connected to an hydraulic pump 18. In operation, with the valves 14 and 16 in positions B and C respectively, the backgauge begins to move at a fast speed. The valve 16 is then operated to the position D so that the fluid has to pass therethrough via a restriction M thereby causing a slow down in the backgauge speed prior to both valves being actuated to their neutral position to stop the backgauge. The backgauge is returned its initial position at high speed by actuating the valves to their A and C positions. The valves may be controlled manually or automatically via a programmed control device. The hydraulic circuit may also be used to actuate the cutting blade.

Abstract: 1376147 Gas turbine engine combustion equipment NISSAN MOTOR CO Ltd 30 Nov 1971 [22 Dec 1970] 55604/71 Headings F1G and F1L The invention relates to a means of minimizing the nitrogen oxide content in the exhaust gases of a gas turbine engine in which diluted combustion gases from a pre-combustion chamber are supplied to the main combustion chamber. In Fig. 2 diluted combustion gases from a pre-combustion chamber 21 are supplied to the main combustion chamber 11 to which air from compressor 16 is supplied as secondary and tertiary air and to which fuel is supplied through an injector. The resulting combustion gases discharge to the turbine 15. The apparatus shown in Fig. 3 comprises an outer casing within which are disposed a pre-combustion chamber 21 and a main combustion chamber 11, air from the compressor passing through passage 22 and entering the pre-combustion chamber 21 through inlets 23 as primary air and through inlets 24 as secondary and tertiary air. A fuel injector 25 and ignition device 26' are provided and the resulting combustion gases pass through swirl device 12 into the main combustion chamber 11 as primary air. Fuel is supplied to the main chamber 11 through injector 13 and secondary and tertiary air are supplied thereto through inlet openings 31, 32 from the passage 22. In Fig. 4 (not shown) the combustion gases from the precombustion chamber 21 are cooled in a heat exchanger (33) before passing to the main combustion chamber. In Fig. 5 (not shown) the combustion gases from the pre-combustion chamber are passed through an auxiliary turbine and then through a heat exchanger, the cooled gases then passing to the inlet of an air compressor to which ambient air also passes. Air from the compressor passes as primary air and secondary or tertiary air to the pre-combustion chamber also to the main combustion chamber, gases passing from the main combustion chamber to the main turbine.

Abstract: 1525241 Sampling COCKSEDGE & CO Ltd 11 Dec 1975 [31 Dec 1974] 56122/74 Heading B8N [Also in Divisions B3 and G3] Apparatus for controlling the operation of a sampling tool for extracting a sample of beet from a stack, comprises a piston and cylinder device 24 to advance and retract the tool 33, fluid supply and exhaust lines 70, 72 to the device and a switch 77 to detect a drop in exhaust pressure to stop the fluid supply and hence the tool advance. The switch 77, normally held open by the exhaust fluid pressure. When the tool meets a fixed object, e.g. the floor of a lorry containing the beet, its advance is prevented and the exhaust pressure drops to cause switch 77 to close and switch multi-port valve 79 over so that the tool is retracted. The tool 33 is rotatably mounted on a frame 17 which is vertically guided in a set of vertical guides 16 of a carriage 10 with wheels 11. Scoops 48 within the tool 33 are advanced and retracted relative to the tool by a hydraulic ram 44. The tool is guided against lateral movement by rollers (49), (50), Fig. 4 (not shown), in a framework (56-59) at the lower end of the carriage 10. The tool guide framework permits slight pivotal movement of the tool and may include shear pins.

Abstract: 1,145,669. Aromatic carboxylic acids. SOC. ITALIANA RESINE S.p.A. 21 Dec., 1967 [23 Dec., 1966], No. 58204/67. Heading C2C. In the manufacture of aromatic carboxylic acids by oxidizing a liquid alkylbenzene with oxygen or a gas containing molecular oxygen, steam is admitted to the reaction vessel above the reaction liquid and the oxidizing gas is used in such excess that oxygen is present in the exhaust gas. The use of steam in this way restrains the risk of explosion, so that the exhaust gases may contain more than 10% of oxygen. The reaction may be effected at 90- 140‹ C. under atmospheric or raised pressure in the presence of a conventional catalyst and, optionally, of an activator and (or) a solvent. An example describes the oxidation of p-xylene to toluic and phthalic acids in the presence of cobalt octoate.

Abstract: 1401769 Fluid-pressure servomotor systems COPES REGULATORS Ltd 22 Nov 1972 [23 Dec 1971] 59875/71 Heading G3P A speed-sensitive control device comprises an oil-pump 39 driven at a speed dependent on the speed to which the device is sensitive to pump oil into a diaphragm chamber 52 to deflect the diaphragm against a loading force and actuate a control valve 65, restrictions 57 and 58 being provided to reduce the pressure in the diaphragm chamber. In the preferred embodiment, the pump plunger 43 is reciprocated by a lever 34 and a cam 32 oscillated through a linkage 29 from the piston-rod of a steam engine driving a cargostripping pump, the steam-supply valve for the engine being controlled by the valve 65 which receives a compressed air supply from a controller (not shown). On the induction stroke of the plunger, oil passes from a bath of oil 38 through holes 46 a filter 47 and a non-return valve 48 into the pump chamber 49. The pumping stroke expels the oil through a further non-return valve 50 and the clearance between a collar 55 and an extension 56 of a plate 53 attached below the diaphragm into the diaphragm chamber. The pressure in the chamber is reduced both by the fixed restriction 57 in proportion to the square of the flow-rate and by an adjustable spring leaf obturator 59 in proportion to the cube root of the square of the flow-rate so that the pressure applied to the diaphragm varies linearly with speed. Compressed air from an inlet 63 is applied to the upper side of the diaphragm and flows through the clearance around a base 67 to a capacity chamber on the inlet side of the actuator for the steam-supply valve. When the oil pressure rises due to an increase in engine speed the valve 65 is lifted to cause the steam valve to move towards its closed position. In a second embodiment, a second non-return valve is provided on the output side of the pump to by-pass the clearance between the collar 55 and extension 56 which are used as a fixed restrictor in place of the restrictor 57. The obturator 59 may be adjusted by a slidable clamp 61 or by a screw having two separate portions of screw thread of different pitch to give a very fine adjustment.
