Abstract: The invention comprises compounds corresponding to the general formula <FORM:0738529/IV (b)/1> wherein Y is an alkylene or cycloalkylene group which interposes 2 or 3 carbon atoms directly between the nitrogen atoms attached thereto; X is an alkylene group which interposes 4 to 12 carbon atoms directly between the indicated nitrogen atoms and which may be interrupted by an ether-oxygen atom and/or bear substituent alkyl groups; Z is a straight-chained or branched alkylene group of from 2 to 6 carbon atoms and A is hydrogen or a methyl, ethyl, n-propyl, isopropyl or butyl group.  Such compounds are obtained by reacting two molecular proportions of the appropriate halogen-substituted alkyl or alkoxylalkyl dialkanolamine, e.g. 2-chlorethoxy-ethyl-diethanolamine with one molecular proportion of the appropriate alkylene diamine.  Alternatively the appropriate symmetrical chloralkyl or chloralkoxy alkyl alkylene diamine such as N,N1-di-(4-chlorobutyl)-ethylene diamine can be reacted with the appropriate dialkanolamine.  In examples (1) 4-bromobutyl diethanolamine and isopropylene diamine are refluxed in alcoholic sodium hydroxide solution to give N,N1-di-(o -iminodiethanol - butyl) - isopropylene diamine; (2) N,N1 - di - (o  - iminodiethanol - dodecyl)-N,N1 - diethyl ethylene diamine of the formula (HOCH2CH2)2N(CH2)12 - N(C2H5) - CH2CH2 -N(C2H5)-(CH2)12-N(CH2CH2OH) 2 is prepared by reacting N,N1-diethyl ethylene diamine with o -chlorododecyl diethanolamine; (3) N,N1 - di - (2 - iminobutanol - ethoxyethyl)-ethylene diamine is prepared by reacting dibutanolamine with N,N1-di-(2-chloroethoxyethyl) - ethylene diamine; (4) N,N1 - di - (4-iminodipropanol - butyl) - N,N1 - diethyl - trimethylene diamine is prepared by reacting N-(4 - chlorobutyl) - dipropanolamine with N,N1-diethyl trimethylene diamine; (5) N,N1-di-(2-iminodiethanol - ethoxyethyl) - N,N1 - dimethyl-ethylene diamine is prepared by reacting N,N1-dimethyl ethylene diamine with N-(2-chloroethoxyethyl) - diethanolamine.  Similarly compounds can be prepared corresponding to the above general formula in which Y represents a 1,2-cyclohexylene radical, e.g. the compound of the formula <FORM:0738529/IV (b)/2> from 1,2 - diaminocyclohexane and N - (2-chlorethoxyethyl) - diethanolamine.  A list of alternative starting materials to illustrate other radicals at A, X, Y and Z in the above general formula is given.  The products are of use as surface-active and wetting agents, detergents and as additives to lubricants and greases.  By reaction with fatty acids they form soap-like products of the formula <FORM:0738529/IV (b)/3> These compounds are useful as assistants in textile and leather manufacture, in glass and metal cleaners, dry cleaners, lubricants and soap compositions.

Title: Machine tool having improved chatter control
IPC: B23Q15/12
Filed: 1968-03-29
Abstract: 1,217,962. Automatic vibration control. GENERAL ELECTRIC CO. March 29, 1968 [April 24, 1967], No. 15364/68. Heading G3R. To maintain constant vibration conditions in a machine tool, electrical signals produced by the vibrations are filtered, rectified and compared with a reference signal representing a desired level of vibration, any difference being applied to correct the movement of the tool relative to the work-piece. In Fig. 2, electrical signals from a vibration detector 1, e.g. an accelerometer, mounted on the tool post of a lathe, are applied to a chatter detector 13 which amplifies and demodulates a selected intermediate band of frequencies to produce a signal at the chatter frequency which is then rectified and integrated to produce a direct voltage proportional to the amplitude of chatter. This voltage is then compared with an adjustable voltage corresponding to a desired low level of chatter so that deviation in one sense or the other produces an error signal which is applied to a numerical control system 14, 15 to adjust the rate of feed of the tool so that chatter is restored to the desired level. Rate of feed thus varies with the distance of the tool from the work-piece supports when machining a long thin bar to maintain optimum machining conditions.
