Abstract: 1,182,735. Spinning; finding yarn ends. LEESONA CORP. 18 June, 1968 [17 July, 1967], No. 28879/68. Headings D1D and D1J. When yarn Y from a spinnaret has filled a yarn bobbin it is cut and passed into an aspirator 22 as a temporary storage whilst the bobbin is changed and as the yarn still proceeds from the spinnaret it passes through a venturi tube (Fig. 3) in the aspirator which produces by means of baffles a vortex flow of air surrounded by a laminar flow of air preventing the yarn from touching the sides of the venturi. As shown an injector 20 when the bobbin is full receives a short blast of air which through a piston moves the nozzle 52 forwards, towards the aspirator entrance 21 this movement operates the cutters 19 through a lost motion device and the yarn end is pushed by the nozzle and then by a delayed blast of air into the entrance 21. In the nozzle the yarn is carried through a tube 73 to the venturi 76. A continuous air jet from the pipe 27 acts through the venturi 76 and by means of baffles 82, 86 produces a vortex flow 83, surrounded by a laminar flow 84. The aspirator is detachable to reposition the yarn on a fresh bobbin. A water droplet may be introduced through a tube 87 in the injection to aid injection.

Filed: 1959-08-26
Abstract: An alkene having the formula <FORM:0889341/IV (b)/1> in which R is a straight or branched chain alkyl radical having 1-9 carbon atoms, is reacted with phenothiazine, carbazole or acridine, at a temperature between 80 DEG C. and 120 DEG C., in the presence of a boron fluoride complex with water, an alcohol, an ether or a nitrile to give a corresponding C-alkylated heterocyclic compound.  The alkyl substituent is the group <FORM:0889341/IV (b)/2> Suitable boron fluoride complexes are those with for example, methanol, ethanol, glycol, diethyl ether, methyl amyl ether, anisole, tetrahydrofuran, dioxan, acetonitrile, benzonitrile, and o, m and p-tolunitrile as well as a complex with water.  With phenothiazine and with carbazole dialkyl derivatives are obtained whatever the proportions of reactants, whereas with acridine a mono-derivative may be obtained. Suitable alkenes for use as starting materials are isobutylene, di-isobutylene, (CH3)3CCH2.C(CH3)=CH2, and tri-isobutylene, (CH3)3C.CH2C(CH3)2CH2C (CH3)=CH2. In certain cases it is possible to use in the reaction mixture the corresponding tertiary alcohol and form the alkene in situ in the reaction mixture.  It is preferred to use a non-polar hydrocarbon solvent for the reaction, e.g. heptane, iso-octane or petroleum ether.  The reaction may be promoted and yields improved by the use of a cocatalyst, e.g. an organic sulphonic acid.  Examples are given of the preparation of 3,7-dioctyl phenothiazine monooctyl acridine, dioctyl carbazole, didodecyl phenothiazine and di-t-butyl phenothiazine.  In all cases the alkyl substituents in the products are of the type <FORM:0889341/IV (b)/3>
