Patent GB-582872-A (GB)
Title: Improvements in or relating to the production of naphthyridones and of naphthyridines therefrom
Filed: 1944-09-21
Abstract: Naphthyridones are obtained by treating a 2-azafluorenone or substitution product thereof with hydrazoic acid or a source thereof, in presence of a mineral acid, advantageously sulphuric acid, the quantity of hydrazoic acid used being somewhat in excess of 1 molecular proportion.  The benz-naphthyridones so obtained are converted into the corresponding halogen-benznaphthyridines which are then employed for the production of other substituted benznaphthrydines.  The halogen derivatives may be obtained by known methods for converting hydroxypyridine, -quinoline or -phenathridine derivatives into the corresponding halogen compounds, a preferred method consisting in heating the benznaphthridone with a phorphorus oxyhalide or with a phosphorus pentahalide in phosphorus oxyhalide suspension at elevated temperature, preferably between 170 and 190 DEG  C.  Reaction is effected in a sealed vessel or alternatively the reactants are heated in an open vessel in an inert high-boiling solvent medium, e.g. nitrobenzene or a dialkylamine such as diethylaniline.  In examples: (1) 1 : 3-dimethyl-2-azafluorenone in concentrated sulphuric acid is treated with aqueous sodium azide and the product is poured into ice to precipitate the corresponding sulphate, from which is isolated 6 : 8-dimethyl-3 : 4-benzo-1 : 7-naphthyrid-2-one by treatment with dilute ammonia; (2) the product of (1) and phosphorus oxychloride are heated in a sealed tube at 180 DEG  C., the residual oil being treated with ice and excess ammonia to isolate 2-chloro-6 : 8-dimethyl-3 : 4-benzo-1 : 7-naphthyridine; (3) the product of (1) and phosphorus oxychloride are heated in a sealed tube at 180 DEG  C. and the residue, after cooling, is treated as in (3), (4) 4-carbethoxy-1 : 3-dimethyl-2-azafluorenone in concentrated sulphuric acid is treated with aqueous sodium azide as in (1) and the product was treated with ice-ammonia, the pptd. sulphate being dissolved in 5 per cent sodium hydroxide, and the filtrate saturated with carbon dioxide to isolate 4-carbethoxy-6 : 8-dimethyl-3 : 4-benzo-1 : 7-naphthyrid-2-one, the enolic form being 4-carbethoxy-6 : 8-dimethyl-3 : 4-benzo-2-hydroxy-1 : 7-naphthyridine.  1-Carbethoxy-4 : 3-dimethyl-2-azafluorenone is obtained by treating the corresponding 4-carboxy compound in ethanolic N/2 potassium hydroxide with aqueous silver nitrate, heating under reflux with ethyl iodide an alcoholic suspension of the silver salt so precipitated, and diluting the concentrated filtrate with water.

Patent GB-146430-A (GB)
Title: Improvements in and relating to the manufacture of fat from spent sulphite cellulose lyes
IPC: C12P7/64
Filed: 1920-07-03
Abstract: The sugar contents of waste sulphite lyes are converted into fat by growing a fungus " endomyces vernalis " in the lye which has previously been aerated and neutralised.  The early growth of the fungus may be assisted by adding nitrogenous substances such as beet juice to the waste liquor or by first growing the fungus in a culture-medium rich in nitrogen and then transferring it to the lye. The first stage of the process is marked by a large absorption of nitrogen and by rapid growth of the fungus.  During the second stage the sugar in the lye is assimilated and converted into fat, and the growth of the fungus is slight.  The masses of fungi are finally removed from the solution and heated for the recovery of fat in any manner.

Abstract: 1,003,761. Valves. ROTORK ENGINEERING CO. Ltd. May 22, 1962 [May 23, 1961], No. 18602/61. Heading F2V. [Also in Division H2] An electrical control unit for a valve actuator includes a switch or pair of switches forming part of a control circuit operating the actuator motor, and each switch is selectively operable either as a limit switch, or as a torque switch, or as a combined limit and torque switch, and is operable in response to the output movement of the actuator and/or the output force, i.e. thrust or torque of the actuator control unit 20 is responsive to axial movement of the actuator motor shaft 11, through a shaft 21 loosely coupled with the motor shaft, and also the rotational movement of the output shaft 14, through a secondary shaft 17, to operate torque and/or limit switches 51 and also other limit switches 46, 47. Axial movement of shaft 21 against a strong spring 59 in response to an increase in torque is transmitted to another short shaft which has a helically threaded end 60 passing through a nut 61 such that the shaft is forced to rotate to operate a switch operating lever 62. The torque setting of switches 51a, 51b, is adjustable by screws 66 mounted in extensions of lever 62 and engageable by a further lever 63 resiliently mounted on the rotating end 60 of the short shaft. Secondary shaft 17 extends into the casing 19 surmounting the control unit and has an extension entering a hollow threaded spindle on which is threadedly mounted a nut 29 movable between pins 28, 32, at two extreme positions on the spindle. A spring 40 prevents nut 29 from rotating when shaft 17 rotates, the nut thus moving along the spindle until it engages pin 28 or pin 32 when it is forcibly rotated to cause a rotatably mounted plate 43 to actuate limit switches 46, 47. If removable screws 68a are inserted into plate 67, which is an extension of lever 62, then rotational movement of plate 43 causes a plate edge to engage a screw and thereby rotate plate 67 to operate the switch operating lever 62 independently os any axial movement of shaft 21, torque switchee 51 then acting also as limit switches. The coupling of shaft 21 with the motor shaft 11 if removable if switches 51 are required to act solely as limit switches. The lower portion of plate 43 has an extension 53 connected with an indicator device 54 of Specification 1,003,764, in which a pointer 55 moves across a dial 56 visible through a window 57 in the casing 19 to indicate the end positions of the valve.
