Title: 2-chlorophenothiazine derivatives
IPC: C07D295/088
Filed: 1957-07-04
Abstract: The invention comprises phenothiazine derivatives of the formula (I) <FORM:0823470/IV (a)/1> and their acid addition salts and quaternary ammonium compound (wherein n is two to six, -CnH2nis a straight or branched alkylene radical having at least two carbon atoms between the valences linking it to the nitrogen atoms, and R is hydrogen or methyl); their S-oxides (and acid addition salts and quaternary ammonium compounds thereof); their N,5-dioxides (and acid addition salts thereof); and processes for the preparation of the compounds (I) by (a) reacting 2-chloro-phenothiazine with (polymethyl - 1 - pyrrolidyl) - alkyl halides of the formula (II) <FORM:0823470/IV (a)/2> or (b) reacting a 2-chloro-10-haloalkylphenothiazine (III) <FORM:0823470/IV (a)/3> with a polymethylpyrrolidine, in both cases in the presence of an alkali-metal compound condensing agent.  The intermediates (II) may be obtained by reacting the appropriate polymethylpyrrolidine with (a) a halohydrin, (b) an alkylene oxide, or (c) a haloester and reducing the resulting pyrrolidyl-alkanoic ester with lithium aluminium hydride, and in each case halogenating the alcohol so formed.  The intermediates (III) may be prepared by condensing 2-chlorophenothiazine with a halohydrin and halogenating the resulting alcohol.  Examples describe the preparation of 10-[3-(2,2-dimethyl - 1 - pyrrolidyl) - propyl] - 2 - chloro - phenothiazine and its hydrochloride; 10-[3-(2,2,4 - trimethyl - 1 - pyrrolidyl) - propyl] - 2 - chlorophenothiazine and its hydrochloride; 10 - [3 - (2,2,4 - trimethyl - 1 - pyrrolidyl) - pro - pyl] - 2 - chlorophenothiazine sulphoxide and its hydrochloride, hydrobromide, hydriodide, sulphate, citrate, acetate, succinate, benzoate, salicylate, lactate, nitrate, phosphate, glycolate, tartrate and ascorbate, and its methobromide, methiodide ethobromide, ethochloride, benzyl chloride and ethyl p-toluene-sulphonate; and 10 - [3 - (2,2,4 - trimethyl - 1 - pyrrolidyl) - pro - pyl] - 2 - chlorophenothiazine N,5 - dioxide and acid additions salts as above. 3-(2,2-Dimethyl-1-pyrrolidyl)- and 3-(2,2,4-trimethyl - 1 - pyrrolidyl) - propyl chloride hydrochloride are prepared by reacting trimethylene chlorohydrin with 2,2-dimethylpyrrolidine and 2,2,4-trimethylpyrrolidine, respectively, and halogenating the hydrochlorides of the resulting 3 - (2,2 - dimethyl - 1 - pyrrolidyl)- and 3-(2,2,4-trimethyl - 1 - pyrrolidyl) - 1 - propanol with thionyl chloride.

The assembly is transversely located by the engagement of the handle hubs with the rose plates 28. The knob 41 is of soft metal and retained in position by a ribbed collar 41a which is forced through a hole 22b in the handle shell. In the form of Fig. 19 for use on bathroom &c. doors the key and lock are omitted, being replaced by an outside handle 42 having an aperture 42a through which a screwdriver may be passed to engage a slot in the spindle for unlocking the door in an emergency. The inside knob 44 is secured on the follower spindle 45 by being forced over longitudinal ribs 45a and the knobs are located transversely of the lock by abutting the sides of the housing.

Abstract: <PICT:0957215/C3/1> <PICT:0957215/C3/2> In a process and apparatus for degassing molten metal, the latter is teemed into a vacuum chamber in a stream of discrete droplets, which are collected in a vessel within the vaccum chamber, and teemed therefrom again in a stream of discrete droplets, whereby the metal falls to the bottom of the chamber, collecting there in a pool, from which it is discharged through a barometric leg.  The metal leaving the vessel in the vacuum chamber may furthermore be subjected to a cascading motion before reaching the bottom of the chamber.  In one form of apparatus, shown in Figs. 1 and 2, metal in receiving vessel 11, sealed to vacuum chamber 10 is teemed into that chamber and collected in vessel 16, which is tiltably mounted on trunnions 17 by which its position may be externally controlled.  Partially degassed metal from vessel 16 cascades down stepped wall 20 and collects in a pool 22 on the floor of the chamber, which it is discharged through barometric leg 23. The latter is sealed by device 24 until a sufficient head of metal has built up. The process may be operated continuously, teeming from vessels 11 and 16 proceeding simultaneously, and the flow of metal from leg 23 may be temporarily interrupted to enable fresh moulds to be brought into position by suspending the flow of metal from vessel 16. The apparatus may be mounted on structure 28, under which moulds 31 pass on trolleys 30, or may itself be mounted on a trolley which moves over stationary moulds.

Abstract: 1425445 Automatic control INTERNATIONAL BUSINESS MACHINES CORP 17 May 1974 [24 Aug 1973] 22232/74 Heading G3R In magnetic tape apparatus, the tape is moved in steps and after each step the error between oblique data tracks on the tape and a tape head is measured and used to modify a subsequent tape step. In the embodiment shown, tape 10 is fed from a supply spool 13 via a vacuum buffer 18 and wound helically round a stationary mandrel 15 to a take-up spool that is driven in steps by D.C. motor 31. The positions of the data tracks are measured by a rotating head in mandrel 15 that detects indicia (25, 26), Fig. 3 (not shown), on the tape. The head to track error is formed at 29 to modify the subsequent tape step as commanded by 38, whose output is compared with the actual movement of the take-up spool. The comparison is used by servo 36 to drive the motor 31 and thus the tape to the commanded position. When this position is reached the motor is locked using a D.C. signal, so that the tape is kept stationary and under tension, for all values of take-up spool size, against the forces exerted by the buffer 18. The tape loop in the buffer is also measured and controlled by servo 20. In an alternative Fig. 6 (not shown) the position servo 36 includes logic elements, a digital counter and a position error integrator.
