Title: Manufacture of halogen-alkyl amidines
IPC: C07D233/20
Filed: 1945-03-20
Abstract: Halogen-alkylamidines are prepared by treating an oxyalkyl-amidine with an esterifying agent capable of converting an alcohol into an ester of a hydrohalic acid, for example, a thionyl halide or a phosphorus halide.  If desired, a diluent may be present such as benzene, chloroform, ethylene chloride or an excess of the esterifying agent.  In examples: (1) 2-oxyacetamidine hydrochloride is gently boiled with thionyl chloride yielding chloracetamidine hydrochloride; (2) thionyl chloride is reacted in the cold with 2-oxymethylimidazoline hydrochloride (prepared by reacting glycollic acid imido-ethyl ether hydrochloride with ethylene diamine) so yielding 2-chloromethyl imidazoline hydrochloride; phosphorus pentachloride may be used in place of thionyl chloride, whilst with phosphorus pentabromide, 2-bromomethyl imidazoline hydrochloride is obtained.  In an analogous manner, there may be prepared chloracet-(b -phenylethyl)-amidine hydrochloride, chloracet-N : N-pentamethyleneamidine hydrochloride and 2-(a -chlorethyl)-, 2-(a -chloroisopropyl)-, 2-(g -chloropropyl)-, and 2-(a -chlorobenzyl)-imidazoline hydrochlorides.  The oxy-alkyl amidines employed as starting materials may be prepared from the corresponding cyan-hydrins by way of the oxy-alkyl imido-ethers.

Title: Improvements in or relating to electric counting circuits
IPC: H03K25/00
Filed: 1947-03-13
Abstract: 633,099. Pulse frequency dividing circuits. STANDARD TELEPHONES & CABLES, Ltd., and GRAYSON, H. March 13, 1947, No. 7001. [Class 40 (vi)] In a frequency dividing circuit a capacitor is charged up in steps by the input pulse train until the potential across it exceeds a predetermined value when switching device is operated and unblocks a valve through which the capacitor discharges, the switching device then being restored to normal and the valve being reblocked after a given delay period. The Figure shows a circuit in which valve 7 is normally cut-off by grid current irow through resistor 20 and is rendered conducting by the input pulses applied at terminals 1, 2 to produce positive-going pulses in its anode circuit, the amplitudes of which are maintained constant by diodes 23, 24. Capacitor 8 is charged up in steps by these pulses via capacitor 27 and diode 28 until the potential across it is such that the normally non-conducting valve 10 of the cathode coupled flip-flop circuit comprised by valves 10 and 11 is rendered conducting and valve 11 is cut-off. The positive pulse at the anode of valve 11 is delayed in the network 13 and renders valve 9 conducting to discharge capacitor 8. When the capacitor has' discharged to earth potential which is ensured by diodes 28, 29, valve 9 is cut-off and the flip-flop returns to its normal state with valve 11 conducting. The resultant negative pulse at the anode of valve 11 cuts-off valve 9 after a delay determined by network 13 and the charging of capacitor 8 recommences. Diode 45 fixes the normal potential of the control grid and cathode of valve 11 and thus the triggering voltage of valve 10 and the output pulse of the circuit is taken from terminal 6.

Filed: 1936-03-09
Abstract: N : N<1>-Dialkoxyalkyl or N : N<1>-alkyl-alkoxyalkyl dipyrazoleanthronyls are made by (a) treating a dipyrazoleanthronyl or an N-alkyl dipyrazoleanthronyl with an ester of an ether of a polyhydric alcohol, or (b) treating a dipyrazoleanthronyl simultaneously or in succession with esters of two different polyhydric alcohol ethers to introduce two different alkoxyalkyl groups, or (c) treating a dipyrazoleanthronyl with an ester of an ether of a polyhydric alcohol and then with an alkylating agent.  The products may be treated with halogenating agents or converted to their leuco-derivatives, such as their leuco sulphuric acid esters. Esters specified are the aryl sulphonic esters (e.g. p-toluene sulphonic ester) of glycol monomethyl or monoethyl ether.  The temperature range employed is 120--200 DEG  C. and diluents such as nitrobenzene, chlorbenzene, o-dichlorbenzene, tri-chlorobenzene, amyl alcohol, naphthalene, or anisol may be used, the reaction being conducted under pressure or not.  The alkali salts (e.g. sodium or potassium) of the dipyrazoleanthronyls may be used.  The products are dyes or dyestuff intermediates, and as dyes may be used, if desired in admixture with N : N<1>-dimethyl or -diethyl-2.2<1>-dipyrazoleanthronyls, for dyeing and printing vegetable fibres (red tints are obtained on cotton), or for colouring lacquers and plastic masses, as well as artificial silk, such as acetate artificial silk.  In examples, the dipotassium salt of 2.2<1>-dipyrazoleanthronyl is (1) dialkylated with the p-toluenesulphonic acid ester of glycol monomethyl or monoethyl ether, or (2) alkylated in either order with p-toluenesulphonic acid ethyl or methyl ester and with the p-toluenesulphonic acid ester of either glycol monomethyl ether or glycol monoethyl ether, without isolation of the monoalkylated product, or (3) monoalkylated with the p-toluenesulphonic acid ester of glycol monomethyl ether to give mono-(N)-methoxyethyl-2 : 2<1>-dipyrazoleanthronyl, which is converted to its potassium salt and treated with ethyl bromide.  Also in examples, N.N<1>-dimethoxyethyl - 2 : 2<1> - dipyrazoleanthronyl or another N.N<1> - dialkoxyalkyl - 2.2<1> - dipyrazoleanthronyl is brominated in fuming sulphuric acid in presence of iodine; the same product may be obtained by dibrominating 2.2<1>-dipyrazoleanthronyl and introducing the methoxyethyl residue.  Two further examples describe the dyeing of cotton with the dyestuff obtained in (1) above.  A sample has been furnished under Sect. 2 (5) of a product prepared by reacting 2.2<1>-dipyrazoleanthronyl with the p-toluenesulphonic acid esters of glycol monomethyl and monoethyl ethers simultaneously.  2.2<1>-Dipyrazoleanthronyl dipotassium salt is obtained by fusing pyrazole-anthrone with potassium hydroxide and alcohol.

[Also in Division C7] A crankshaft having an oil-hole in a main bearing portion or in a crankpin is given improved torsional fatigue properties by induction hardening the relevant portion of the shaft so that a hardened surface layer is produced which increases in depth towards the oil hole. The depth may be such that the internal surface of the oil-hole is hardened along its entire length, or only along a part thereof. Apparatus consists of two inductors, one of which produces a heated zone extending over a part only of the surface to be hardened while the other heats the whole of that surface, and means for successively energizing the two inductors. As illustrated, inductor 7 is first energized for a period t 1  while the shaft 6 is rotating, and inductor 8 is then energized, preferably at a higher frequency, for a period t 2 . Finally the shaft is quenched by liquid or gas. The two inductors may be contained in the same easing, and may be independently controllable as to time frequency and current.
