Title: Improvements in or relating to the production of substituted acridines
IPC: C07D219/10
Filed: 1944-06-14
Abstract: Acridine amidoximes of the general formula <FORM:0595401/IV/1> wherein R1, R2, R3 and R4 each represent hydrogen or alkyl, aryl or aralkyl radicals, are obtained by treating a meso-substituted cyanoacridine of the formula <FORM:0595401/IV/2> in which R1 and R2 are as previously defined with hydroxylamine or with an N-substituted hydroxylamine.  In addition to the cyano-substituent there may also be present in either or both of the benzenoid nuclei one or more other substituents, such as alkyl, e.g. methyl or ethyl, alkoxy, e.g. methoxy or ethoxy, alkyl mercapto, e.g. methyl or ethyl mercapto, halogen, amino, substituted amino or nitro groups.  Specified cyanoacridines are: 3-cyano-9-aminoacridine, 2-methoxy-6-cyano-9-aminoacridine, 2 - methoxy - 6 - cyano - 9 - (g - diethylamino-n-propylamino)-acridine, 2-methoxy-6-cyano - 9 - (g  - diethylamino - b  - hydroxy - n - propylamino)-acridine and 2-methoxy-6-cyano-9-(a  - methyl - d  - diethylamino - n - butylamino)-acridine.  Specified substituted hydroxylamines are the N-methyl, -ethyl, -phenyl and -benzyl derivatives.  The group -NR1R2 may be primary or secondary alkylamino, the alkyl group or groups being straight or branch chain groups, e.g. n-propyl, n-butyl, iso-propyl or a -methyl-n-butyl or especially omega-dialkylamino alkyl groups, e.g. diethylaminoethyl, a -methyl-b -diethylamino-ethyl, g -diethylamino-n-propyl, g  - diethylamino - b - hydroxy - n - propyl or a  - methyl - d  - diethylamino - n - butyl (R2 advantaneously representing such a group and R1 hydrogen). The reaction may be carried out in the presence of suitable media such as the monohydric alkanols, e.g. ethanol or isopropanol.  In examples: (1) 2-methoxy-6-cyano-9-aminoacridine is mixed with aqueous hydroxylamine (prepared from the hydrochloride in the presence of alcohol and pyridine) and the solution is refluxed, yielding 2-methoxy-6-guanoxyl-9-aminoacridine; (2) 3-cyano-9-aminoacridine is heated with hydroxylamine as in (1) yielding 6-guanoxyl-9-amino-acridine; (3) 3-cyano-9-phenylamino-acridine; and (4) 3-cyano-9-benzylamino-acridine are refluxed with hydroxylamine as in (1) yielding the corresponding 3 - guanoxy - substituted compounds.  ms - Amino - cyanoacridines of the second general formula above are obtainable by the action of ammonia or a primary or secondary amine or a ms-chloracridine containing a cyano group in one of the benzenoid rings; e.g. 3 - cyano - 9 - amino-, -phenylamino- and -benzylamino-acridine are obtained by treating 3-cyano-9-chloroacridine with ammonia, aniline and benzylamine respectively, in phenol solution.

Title: An improved method of incorporating an elastic thread in a fractional portion of a knitted article during the production of same on a rib knitting machine
IPC: D04B1/18
Filed: 1931-04-17
Abstract: 375,470. Knitting. BIRD & YEOMANS, Ltd. and OSBORNE, W. T., Hinckley Road, Earl Shilton, Leicestershire. April 17, 1931, No. 11439. [Class 74 (ii).] Aknitted article having an elastic thread knitted in at one or both ends for a few loops only, the bulk of the thread being laid in, practically without tension, in an unknitted state between rib and plain loops, is made on a Wildt trick-wheel rib machine, somewhat modified as follows :-The dial needles are retracted by the action of the pattern drum 17, which is racked round by a pawl 18. A plate 22 below the drum 17, pivoted to an oscillating lever 23 carries a projection 25 which can come under the pawl 18 to prevent the drum from being turned. Pattern levers 26 pivoted at 27 are thrust forward selectively by the drum. A plate 30 movable vertically under pattern control carries cams 31, 32 which engage one or other of cams 34, 35, 36 moving round with the yarn guides and put feeders 13, 14 in and out of action. A block 38 on the latch ring carries two vertical spindles 39, 40. The spindle 39 carries a lever 41 and a mutilated gear 42 gearing with a similar gear 47 on the spindle 40 on which is pinned a cam 46. A link 45 couples the cam 46 to cams 43, 44 loose on the spindle 39. The cam 46 can be prevented from turning by the nose 49 of a cam 48 pivoted on the block 38. The lever 41 is coupled by a link 52 to a cam 53 carried in the dial cam cap. The cam 53 is pushed in or out, to determine whether the dial needles shall be retracted or follow their normal course, by the action of humps 51 on the revolving cams 43, 44, 46, 48. At a course prior to the introduction of elastic thread 54 all the cylinder needles 11 are retracted by pattern drums 15, 16. Knitting of the yarn 55 from the feeder 14 then proceeds on dial needles only. After one revolution the feeder 13 is moved into action, the end of the thread 54 being still retained in a trapper. The thread is taken by the dial needles and when a few loops are knitted in, the end is released, the feeder 14 is moved out of action and simultaneously the cam 53 is moved to retract the dial needles. There may be an overlap of three dial needles between the thread 54 and yarn 55, after which the former is laid in in the usual way, until the desired number of courses containing elastic thread are completed, when the feeders 13, 14 are exchanged and the thread 54 is trapped and cut. The thread 54 is positioned between the feeder 13 and the point where it is laid in by a depending finger. Specification 267,876, [Class 74 (ii), Knitting &c.], is referred to.

Abstract: 1373211 Alcohols from the indirect hydration of olefins H A F TOPSOE 26 Nov 1971 [26 Nov 1970 27 April 1971] 56273/70 Heading C2C Ethyl alcohol, iso-propyl alcohol and secbutyl alcohol are manufactured by a continuous process which comprises the steps of (1) absorbing at below 5 atmospheres absolute the corresponding olefin from a gas containing it into an absorbing medium comprising aqueous H 2 SO 4  of concentration, calculated as the percentage ratio H 2 SO 4  ; (H 2 SO 4 +H 2 O), of 80-98% by weight when absorbing ethylene and 50-85% by weight when absorbing is 0- propylene or 1- or 2-butylene, the flow rates being such as to prevent the absorption degree from exceeding 0À5 moles of reacted olefin per mole of H 2 SO 4 , (2) hydrolysing after further heating, if necessary, the resulting adsorbate by the addition of excess H 2 O in the form of steam heated to a temperature high enough for obtaining the desired temperature in the next following step, (3) separating the alcohol so formed by stripping, the stripping being operated either 3(a) under such conditions that there is no dilution of the absorbing medium, in which case there is no further treatment of the absorbing medium prior to the final step, or 3(b) under such conditions of temperature and pres. sure that there is a dilution of the absorbing medium not exceeding a numerical value of 5% by weight absolute, and not exceeding a value allowing the original concentration of the absorbing medium to be restored in an adiabatic flash evaporation to which it is, in such case, subsequently subjected for restoring said concentration prior to the final step, and (4) collecting the absorbing medium and cooling it and recycling it for re-use in the absorption step. The absorption step may be catalysed by silver ions added as silver sulphate. Examples describe the manufacture of ethanol by the absorption of ethylene into 90% H 2 SO 4  at atmospheric pressure in the presence of 0À5 to 7% Ag+ and also in uncatalysed systems. The adsorbate from step (i) is heated by a heat exchanger prior to entering the stripping apparatus where it is contacted with steam. Hot water is passed through the stripper to wash H 2 SO 4  vapour from the alcohol vapour product. The reformed absorbing medium is cooled in the heat exchanger, in one case being previously concentrated in an adiabatic flash apparatus. The manufacture of iso-propanol is also described.

Title: Improvements in and relating to the vulcanisation of rubber
IPC: C08K5/18
Filed: 1933-04-21
Abstract: By incorporating a small quantity such as from 1/10 to 3 per cent of a -polyoxymethylene in a rubber mix containing a semi-ultra or ultra accelerator, for example, mercaptobenzothiazole zinc dimethyl dithiocarbamate, the reaction product of mercaptobenzothiazole and diphenylguanidine, or an aldehyde-amine condensation product such as that formed from butyraldehyde and aniline, scorching at temperatures below 260 DEG  F. is substantially prevented, and the mixture can be stored before vulcanization without the necessity for cooling.  The admixture of a -polyoxymethylene also prevents gelling of self-curing or air-curing cements, and lessens the amounts of softeners such as pine oil or pine tar which need to be incorporated with rubber stocks as scorch retarders.  As a constituent of heavily loaded stocks, such as rubber flooring, sole, toplift, and bead stocks, they also serve to improve the elastic qualities.  The rubber compositions to which the invention is applicable may also contain reinforcing pigments, activators, softening agents, antioxidants, &c.  Examples of mixes are given.  The Specification as open to inspection under Sect. 91 comprises also the use of the following substances as scorch retarders:-2-nitrobrom-4-benzenesulphonic acid, phthalic anhydride, glyceryl phthalate, dimethyl sulphate, glycol linoleate, glyceryl abietate, zinc resinate, benzoin, zinc abietate, cholesterol, pyridyl glycose 2-4-dinitrochlorbenzene, and triphenylthiophosphate.  This subject-matter does not appear in the Specification as accepted.

Abstract: 342,215. Brush holders. BERCHTENBREITER, H., 14, Virchowstrasse, M³nich, Germany. April 14, 1930, No. 11778. [Class 35.] To allow the individual brushes of an axiallydisposed row to adjust themselves for wear independently of the others in the set the pressure is applied by a member which is common to all of the brushes and acts on them through an intermediate member or members of limited elasticity such as to allow independent movement of the individual brushes. In the form shown in Fig. 1, the pressure of the spring g is applied to the brushes a in the box b by means of a rigid bar f and an intermediate elastic member d composed of felt, wire fabric, rubber or the like. This member may be in parts individual to the separate brushes, as shown on the right-hand side, or common to several brushes, as on the left-hand side. When the member d is of conducting material, it may form a part of the path conducting the current to or from the brushes. Fig. 3 shows a form in which a pressure due to a tension spring m is transmitted to the brushes by a common rocker k through an equalizing member or members i having similar properties to those of the member d, Fig. 1. In another form, rigid fingers bearing on the brush tops are bedded between elastic layers in a common rocking member arranged similarly to the rocker k, Fig. 3.
