Abstract: 374,235. Weighing-apparatus fitted to cigarette-weighing machines. UNITED CIGARETTE MACHINE CO. AKT.-GES., 5, Junghansstrasse, Dresden, Germany. May 16, 1931, No. 14539. Convention date, July 11, 1930. [Class 143.] . From a cigarette making machine of the continuous rod type cigarettes are periodically diverted and conveyed to a balance pan, the throw of which is utilized to regulate the tobacco supply, the direct passage of cigarettes to the packing machine being resumed during the weighing operation. Troughs f, g contain belts which convey oppositely tipped cigarettes and deposit them in separate rows on the belt z. A third trough h leads to a table k resting on a reciprocating support m in line with a balance pan q. A pivoted switch directs the cigarettes alternately along the troughs f, g and periodically is diverted to supply the trough h. As the table k comes over the pan q, the table support is lowered, and a sliding rod withdraws a catch from the support of the pan. The. previously weighed cigarettes are removed from the table by a hook, and fall into line with those conveyed directly by the trough f.

Title: New cyclic diamines and process for their manufacture
IPC: C07D487/04
Filed: 1959-04-30
Abstract: The invention comprises compounds of the general formula <FORM:0918204/IV (b)/1> in which R1 is an organic radical capable of being introduced into a tertiary amine group by quaternation by known methods and R2 represents the same groups and in addition hydrogen or an acyl radical, R1 having more than 1 carbon atom when R2 is hydrogen, and salts, quaternary compounds and N-oxides of these compounds.  R1 may be, for example, alkyl, halogeno-alkyl, hydroxyalkyl, aralkyl, alkoxyalkyl or an aryloxyalkyl group.  These compounds may be obtained by quaternating a 1:2-trimethylene-pyrazolidine by known methods, treating the quaternary ammonium compound so obtained with a p  hydrogenating agent and, if desired, introducing a further substituent into the 5-position of the 1-substituted 1,5-diaza-cyclooctane so obtained. If desired any hydroxy group present in a group attached to a nitrogen atom may be converted to an ester group, an ester group may be converted to an amino group or a halogen atom into an alkoxy group.  The diazacyclooctane compound may be treated with an inorganic or organic acid to form an acid addition salt, or with an organic halide or a sulphonic or sulphuric ester to form a quaternary ammonium salt, or with hydrogen peroxide to form an N-oxide.  The 1,2-trimethylene-pyrazolidines may be quaternated, for example, by reaction with an ester of formula R1X in which X is a halogen atom or a hydroxyl group esterified with a sulphonic acid or with sulphuric acid.  The 1-substituted 1,2-trimethylene-pyrazolidinium salt is preferably hydrogenated with nascent hydrogen, e.g. by treating with aluminium amalgam in the presence of water.  The 1-substituted 1,5-diazacyclooctane so obtained may, if desired, be treated by known methods to introduce a further substituent into the 5 - position. Examples are given of the preparation of (a) 1-ethyl-1,5-diaza-cyclooctane; (b) 1-(g -hydroxypropyl)-1,5-diaza-cyclooctaine; (c) 1-(g -phenoxypropyl)-1,5-diazacyclooctane; (d) 1-(b -hydroxyethyl)-1,5-diazacyclooctane; (e) 1-lauryl-1,5-diazacyclooctane; (f) 1-(41-hydroxybutyl)-1,5-diazacyclooctane; (g) 1-(g -bromopropyl)-1,5-diazacyclooctane; (h) 1-(g -diethylaminopropyl)-1,5-diazacyclooctane; (j) 1-(g -ethoxypropyl)-1,5-diazacyclooctane; (k) 1 - methyl - 5 - benz-hydryl-1,5-diazacyclooctane; (l) 1-methyl-5-(b  - hydroxypropyl)-1,5-diazacyclooctane; (m) N-ethyl-N1-acetyl - 1,5 - diazacyclooctane; and their dihydrobromides and also of N-trimethylene-1,5-diazacyclo-octanonium bromide, N,N - diethyl - N1 - acetyl - 1,5 - diazacyclo - octanonium bromide and N - methyl-N-(g -phenoxypropyl) - N1 - acetyl - 1,5 - diazacyclooctanonium bromide.

The products are Soluble in many organic solvents and may be used for dyeing lacquers, such as alcohol, cellon and nitrocellulose lacquers, for dyeing resins and fatty acids, and as pigments. In examples, (1) the sodium salts of 1-amino-4-phenylaminoanthraquinone-2-sulphonic acid and of 7-mtolylazo-1-benzoylamino-8-oxynaphthalene - 4 : 6- disulphonic acid are precipitated with d:phenyliodonium chloride: instead of the latter compound a sulphonium salt, such as diphenylmethylsulphonium hydroxide or phenyldiethylphosphine hydrochloride, tolyldiethylphosphine hydrochloride, or phenyldiethylmethylphosphonium iodide may be used, (2) the sodium salt of 1 : 4-dip - toluido - 5 : 8-dioxyanthraquinone-disulphonic acid is treated with the di-o-tolylmethylsulphonium salt of methylsulphuric acid or with triethylp-tolylphosphonium iodide, and (3) the dyestuff obtained by coupling diazotized aminoazobenzene with sodium 2-naphthol-8-sulphonate is treated with triethyl-p-tolylphosphonium iodide.
