Patent GB-581259-A (GB)
Title: Process for the preparation of alkylation derivatives of dihydroxydibenzanthrone
IPC: C09B3/36
Filed: 1944-08-15
Abstract: Completely alkylated dihydroxydibenzanthrones are purified and separated from non-alkylated or incompletely alkylated products by a process which comprises vatting the crude material in the presence of an aqueous caustic alkali solution of a heterocyclic nitrogen base, oxidizing the vatted compound and filtering off the precipitated dye. If desired, the vatted solution may also be filtered as an additional purification step.  Heterocyclic bases mentioned as suitable include pyridine and its homologues, polymethylene imines and thiazoles.  The temperature of the solution is not critical.  Room temperature may be employed, but it is preferred to work at a temperature of 50-60 DEG C.  The concentration of the solutions in which the operations are conducted is also not critical, but for efficient and economical working should not be below 25 per cent nor above 50 per cent.  A preferred value is 37 1/2 per cent.  The vatting operation may be carried out either by means of a sodium hydrosulphite, nacent hydrogen, molecular hydrogen and a catalyst or by other means used in the vatting of vat colours.  The process of the present invention is particularly effective when used to treat alkylated dihydroxydibenzanthrones which have been prepared by alkylation at a low temperature, such as from 60-130 DEG  C.  When alkylation has been conducted at a higher temperature, the results are less favourable.  The filtered purified dyestuff is preferably washed with the solvent of like kind used in vatting the dye.  If the solvent used is relatively volatile such as pyridine, it may be recovered from the mother liquors by distillation.  Examples are given illustrating the invention in which dimethoxy-, brominated dimethoxy-, diethoxy- and the ethylene and di-isopropyl ethers of dihydroxydibenzanthrone are used and in which the solvents employed include pyridine, N : N1 : N11-triethyl-sym.-hexahydrotriazine, a -, b -, or g -picoline, 2 : 6-lutidine, hexamethylene imine and a -pipecoline.  Specification 546,997 is referred to.

Title: Improvements in or relating to machines for manipulating belts of cartridges for automatic guns
IPC: F42B39/10
Filed: 1941-12-16
Abstract: 588,603. Cartridge belts. HALL, C. T., HARRIS, R. W., and MOLINS MACHINE CO., Ltd. Dec. 16, 1941, No. 16252. [Class 92 (ii)] A machine for removing some of the cartridges from a belt and replacing them with others of a different kind, for example, those with tracer bullets, comprises a shaft 18, operated from a hand wheel 13 or a motor, the shaft serving to actuate an eccentric 20 through which the belt is intermittently advanced over a table 4, and a cam 45 for operating a link 62 serving to retract and insert the cartridges to be removed and inserted, respectively. From the eccentric 20 movement is transmitted through the connecting rod 22, lever 24, link 26, pivoted ratchet lever 28, ratchet wheel 80 and toothed wheels 31, 32 to sprockets 6, the upper portions of which project through the table 4 to engage the links of the belt. Backward movement, due to the weight of the belt, is prevented by a locking pawl 34, and extent of advance with consequent frequency of replacement is determined by the point of attachment of the link 26 to the lever 33. During belt-rest periods the cam 45, driven through bevel gearing, moves the roller 65 carried by the sliding link 62 along the fixed cam groove 66 which is raised at both' ends. The claw 64 as it falls engages the rim of a cartridge which is then withdrawn by movement of the work. The cartridge is received on a placform 54 in a swinging carriage 51 operated from the cam 59 on the shaft 18. The carriage 51 is also formed with a recess 52 which has received a cartridge from a magazine 8. As the carriage swings, this cartridge is brought into alignment with the end face 63 of the link 62 which, on its return movement, pushes the cartridge into the vacated belt pocket while the withdrawn cartridge falls into a shoot 67. The upper surface 53 of the carriage prevents premature falling of the succeeding cartridge in the magazine 8 while lateral interference with the inserted cartridge is prevented by the upper cupped end of a spring-impelled pivoted lever 77. When not required for this purpose, the - lever is depressed by a pin 83 which engages a recess in the associated lever 78. Specification 539,184 is referred to.
