Abstract: 911,671. Magnetic core storage devices. HELL, R. March 9, 1959 [March 8, 1958], No. 8081/59. Addition to 817,761. Class 38 (2). [Also in Group XL (b)] In a construction of storage core, Fig. 4, a magnet core 78 carries soft iron yokes 81, 82 embracing a highly permeable magnetic core 83 with a central aperture 84. If an intense current of short duration is passed through the coil 79, the core 78 is permanently magnetized and a current through conductor 85 does not produce a pulse in conductor 86, whilst a pulse is provided if the core 78 is not energized. The storage core is returned to its normal condition by a pulse through the coil 80. In a modified construction, Fig. 5, a disc 87 of a suitable ferrite has two eccentrically arranged apertures of different diameters, a control winding 90 passing through the larger hole 88 and receiving a strong magnetizing pulse. Two windings 91, 92 pass through the smaller aperture 89, the sampling pulses being applied to these two windings in alternation, and the output pulse, when the core is magnetized being taken from the other of the two windings.

Filed: 1970-02-24
Abstract: 1,274,360. Electric motors. MOSKOVSKY ORDENA LENINA ENERGETICHESKY INSTITUT. 24 Feb., 1970, No. 8782/70. Heading H2A. [Also in Division G1] The position of the rotor of a brushless D.C. motor is sensed by passing high frequency A.C. through the motor windings and sensing when the A.C. in the individual windings exceed a predetermined value, the A.C. in any given winding varying with the position of the rotor. The motor shown comprises three windings 1, 2, 3, energized sequentially from a D.C. source by thyristors 31, 32, 33. A.C. is passed-through the windings from secondary windings 7, 8, 9, of a transformer supplied from a h.f. source. A.C. only passes through a given winding when a magnetic amplifier, e.g. 37, in series with each secondary winding, is saturated by the D.C. flowing through the corresponding commutating thyristor. Low pass filters 22, 23, 24, in series with the windings 1, 2, 3, prevent A.C. from. flowing in the D.C. circuits. Capacitors 4, 5, 6, prevent D.C. from flowing in the A.C. circuits. Operation.-Assuming windings 1 to be energized with D.C., A.C. will flow through the winding from the transformer secondary winding 7. When the A.C. exceeds a pre-set value determined by a diode 40 and resistor 46, transistor 43 is turned on and triggers the thyristor 32 of the next stage. A commutating capacitor 34 turns off thyristor 31, magnetic amplifier 37 becomes unsaturated and stops the A.C. flowing in winding 1. At the same time an RC locking circuit 50, 53 increases the current through diode 41 and resistor 47 and so prevents transistor 44 from triggering the thyristor 33 of the next following stage.

Title: Process for crimping filaments
IPC: D02G1/16
Filed: 1975-03-04
Abstract: Thread-like structures conveyed by means of a flowing heated gas are guided through the first treatment space of constant cross-section of an elongate tubular treatment chamber subdivided into two successive treatment spaces and are thereby heated. After they enter the second treatment space advantageously widening abruptly in respect of its cross-section and provided with longitudinal slits for the radial suction of heated gas used as a conveying and heating medium, the thread-like structures are swirled before they strike the plug of compressed, already crimped thread-like structures. The heated gas, which has fulfilled its purpose as a conveying and heating medium, is sucked off completely, preferably in the upper part of the second treatment space, through the longitudinal slits in the radial direction, in such a way that no appreciable gas flow in the conveying direction now takes place. The thread-like structures travel through the rest of the second treatment space in crimped form as a plug. When this process is adopted, yarns having a very good and uniform crimping value can be obtained even at texturing speeds of more than 2000 m/min.

Title: Heterocyclic compounds
IPC: C07D417/06
Filed: 1954-03-26
Abstract: The invention comprises compounds of the formula <FORM:0772179/IV(b)/1> wherein R1 is an alkyl radical containing not more than 4 carbon atoms; R2 and R3 are hydrogen or ring-attached halogen atoms or alkyl or alkoxy groups; Alk. is a branched or unbranched alkylene group containing not more than 3 carbon atoms in a straight chain; and X and Y each represents either a direct linkage or a branched or unbranched alkylene group containing no more than 3 carbon atoms in a straight chain between the adjacent nitrogen atom and the CH group and salts of such compounds.  Such compounds are obtained by reacting in the presence of a basic condensation agent a phenthiazine of the formula <FORM:0772179/IV(b)/2> with a heterocyclic bromide or iodide of the formula <FORM:0772179/IV(b)/3> wherein Z is bromine or iodine.  As a condensation agent an alkali metal or an amide, alcoholate or hydride of an alkali metal is suitable.  In examples: (1) 1-methyl-3-bromomethyl-piperidine and phenthiazine are reacted in the presence of sodamide to form 10-[(1-methyl-3-piperidyl)-methyl] phenothiazine; (2) similar reactions are used for the preparation of (a) 10-(1-ethyl-3-piperidyl) phenothiazine, (b) 10-(1-n-butyl-3-piperidyl) - phenothiazine, (c) 10 - (1 - methyl - 4 - piperidyl) phenothiazine, (d) 10-(1-methyl-4-piperidyl) 2 - chlorophenothiazine, (e) 10 - (1-methyl - 3 - piperidyl) phenothiazine, (f) 10-(1-methyl - 3 - pyrrolidyl) phenothiazine, (g) 10-(1 - methyl - 4 - piperidyl) - 4 - chlorophenothiazine, (h) 10 - (1 - methyl - 3 - piperidyl) - 4 - chlorophenothiazine, (i) 10 - (1 - n - propyl - 3 - piperidyl) - 2 - methylphenothiazine, (j) 10-(1-n - propyl - 3 - piperidyl) - 3 - methylphenothia - azine, (k) 10 - (1 - methyl - 3 - piperidyl) - 2 - methoxyphenothiazine, (l) 10 - (1 - n - propyl-3-piperidyl) - 4 - methylphenothiazine, (m) 10-(1-methyl - 3 - piperidyl) - 3 - methoxypheno - thiazine ("Chemical Abstracts" numbering). Picrates and/or oxalates and hydrochlorides are prepared of such compounds.  1-Methyl-3-bromopyrrolidine is prepared by reacting ethyl acrylate and methylamine and reacting the resulting ethyl 2-methylaminopropionate with ethyl bromoacetate to give ethyl 2 - (N - methyl - N - carbethoxymethyl) aminopropionate.  This by the Claisen condensation gives 1 - methyl - 2 - carbethoxy - 3 - pyrrolidone which is saponified and then concentrated by boiling to give N-methylpyrrolidone.  The latter is hydrogenated to form N-methylpyrrolidol which with hydrogen bromide gives 1-methyl-3-bromopyrrolidine.
