Title: 10-dialkylaminoalkylphenothiazine-9-oxide derivatives and a process for their production
Filed: 1956-05-03
Abstract: The invention comprises 3-halogeno-9-oxyphenthiazines of the formula <FORM:0797628/IV (b)/1> (wherein X represents chlorine or bromine, A is a divalent hydrocarbon radical containing 2 to 4 carbon atoms, and R1 and R2 represent methyl or ethyl radicals), acid addition salts thereof, and processes for their preparation by: (a) oxidation of an acid addition salt of the corresponding 3 - halogeno - 10 - dialkylamino - alkylphenthiazine with hydrogen peroxide or an organic peracid; (b) oxidation of a 3-halogenophenthiazine with hydrogen peroxide or an organic peracid and reaction of the resulting 9-oxide with an amino-alkyl halide of formula Y.A.NR1R2 (Y represents a halogen atom) in the presence of a hydrogen halide acceptor. Specified acid addition salts include those with hydrochloric, sulphuric, hydrobromic, phosphoric, nitric, picric, maleic, tannic, acetic, oxalic, succinic, tartaric, citric, and malonic acids.  The oxidation is preferably effected between 50 DEG  and 100 DEG  C. in methanol, ethanol, acetic acid, acetone, aqueous acetone or mixtures of these solvents, using hydrogen peroxide, peracetic or perbenzoic acid, and in neutral or acid conditions when a 10-substituent is present.  The reaction with Y.A.NR1R2 is preferably carried out in benzene, toluene or xylene in the presence of sodamide, or an alkali alkoxide, alkali metal, or alkali metal hydroxide.  In examples: (1) 3-chlorophenthiazine in methanol or ethanol is treated with 35 per cent hydrogen peroxide yielding 3-chlorophenthiazine-9-oxide, which is treated with sodamide and then refluxed with dimethylamino-g -chloropropane in xylene to give 10-(31-dimethylaminopropyl)-3-chloro-phenthiazine-9-oxide, characterized as its picrate, hydrochloride, oxalate, maleate, citrate and tartrate; (2) 10-(31-dimethylaminopropyl) - 3 - chlorophenthiazine hydrochloride in boiling methanol is treated dropwise with hydrogen peroxide, the mixture concentrated, basified and 10 - (31 - dimethylaminopropyl) - 3 - chlorophenthiazine - 9 - oxide extracted with benzene; (3) and (4) as in (2), commencing with the sulphate and oxalate salts respectively.

Title: Improvement in wringers and the like
IPC: C14B11/00
Filed: 1939-05-09
Abstract: 528,556. Wringers; machinery guards. LOVELL MANUFACTURING CO. May 9, 1939, No. 13869. Convention date, May 24, 1938. [Class 138 (ii)] [Also in Group XXIV] A power wringer provided with a safety deviceoperated by displacement of the wringer on its support has means for repositioning the wringer. by the action of resetting the safety device. The wringer is supported by two pairs of parallel links 33 from a head 27 mounted on a pillar entering the power shaft for driving the lower roll 4 through shaft 29, bevel gear in the head and clutches 38, 43. Pressure is applied to the rolls by a spring 11 carried by a top plate 14 secured by a hinge 16 and a toggle 17, 18. The pressure on the rolls is released by displacement of the wringer from its centralized operative position, for example, by a pull or push of the operator in case the fingers are caught, this movement causing or allowing a trip rod to move longitudinally against the toggle lever 17 so as to break the toggle and release the top plate 14. This release of pressure permits the coned clutch member 43 to be pressed back by an enclosed spring so as to disengage its driving- connection with pins 45 on the roll shaft. In Fig. 1 the trip rod 51 is pressed back against a spring 52, to release the toggle and thus the roll pressure, by one of the fingers 48 on the parallel links 33 operating on a cam plate 50 when the wringer is displaced and causes the links to swing, and the cam operates on thefingers to centralize the wringer on resetting of the toggle. In Fig. 6 the trip rod 53 is associated with a spring 57 in unison and tension and carries a disc 62 with lugs 63, 64 bearing against a projection 65 on the head 27, and with radial ribs 58 slidable through and normally engaging behind a keyhole slot in the wringer frame. When the wringer is displaced the disc 62 is rocked by the projection 65 to align the ribs 58 with the slot, whereupon the spring 57 moves the rod to break the toggle. On resetting the toggle the rod is pressed back and the spring 57 rotates the ribs to engage the frame behind the slot.
