Title: Process for the production of aziridines
IPC: C07D203/08
Filed: 1960-08-24
Abstract: Aziridines are produced by reacting, in the presence of an acid acceptor, a compound having the formula <FORM:0923528/IV(a)/1> , in which R is hydrogen or a hydrocarbon or substituted hydrocarbon radical and X stands for halogen, sulphate ester or sulphonic ester groups with ammonia or a primary amine, in which the amino nitrogen is linked to an aliphatic carbon atom, and separating the aziridine formed from the reaction mixture before it has further reacted to form a diamine or polymeric amino compound.  Suitable amines are, for example, methylamine, butylamine, dodecylamine, octadecylamine, isopropylamine, 2-octylamine, allylamine, oleylamine, propargylamine, cyclopentylamine, cyclohexylamine, benzylamine, phenethylamine, 1-phenyl-2-propylamine.  Diprimary amines may be used to produce the corresponding bis-aziridines.  The other reactant may be, for example, ethylene chloride, ethylene bromide, ethylene chlorobromide, bis(2-chloroethyl) sulphate, 2-bromoethyl benzene sulphonate, higher homologues of these and analogous derivatives of styrene, stilbene, and a -methylstyrene.  The reaction may be carried out from about 0 DEG  to 200C., the range 20-150 DEG C. being preferred.  The acid acceptor may be excess ammonia or amine or an inorganic base such as an alkali or alkaline earth metal oxide, hydroxide or carbonate.  An inert solvent may be used if desired, and the process carried out at superatmospheric pressure if necessary.  Examples are given of the reaction of (a) ethylene chloride and ammonia to give aziridine; (b) propylene chloride and ammonia to give 2-methyl-aziridine; (c) 2-chloroethyl benzene sulphonate and ammonia to give aziridine; (d) ammonium 2-chloroethyl sulphate and ammonia to give aziridine; (e) bis(2-chloroethyl) sulphate to give aziridine and (f) ethylene chloride and n-butylamine to give 1-(n-butyl)-aziridine.

Title: Improvements in or relating to hemstitching devices
IPC: D05B3/04
Filed: 1936-10-28
Abstract: 471,229. Sewing - machines. GREIST MANUFACTURING CO. Oct. 28, 1936, No. 29299. Addition to 419,708. [Class 112] A hem - stitching attachment of the kind described in the parent Specification has a rotatable cam member carried by the frame and a spring-biassed lever actuated by the cam member, to move the feed bar longitudinally of the frame. The operation of the device is as follows. Assuming that a hole has been made in the cloth by the piercer 51 and the cloth has been fed forwardly so that the needle registers with the hole, with the parts in the position shown in Fig. 1, the needle bar 12 descends to make a stitch. The needle bar, during its descent, strikes the part 47a of the piercer arm 47 to drive the piercer into the cloth to make the next hole. When the needle bar moves upwardly, the lever 42 engaging the needle-attaching screw also moves upwardly and the pawl 43 moves the toothed wheel 44 through one tooth, rotating the shaft 29. This causes one of the arms 58 to ride up the surface 59 and move the piercer arm 47 downwardly, driving the piercer again into the second hole, tending to increase the size of the hole. As the piercer is moving downwardly, the cam surface 77 moves the feed bar 60 downwardly into contact with the cloth, slightly raising the presser foot 22. The lateral cam surface 79 on the cam wheel 35 engages the lug 68 to move the front end of the feed bar 60 to the left to feed the cloth laterally. The piercer arm is also moved laterally with the piercer in the hole, so assisting in feeding the cloth laterally. The needle bar then descends to cause the needle to reenter the cloth to make a stitch at one side of the hole. When the needle bar again moves upwardly, a second stroke of the lever 42 will occur. During this stroke, the cam surface 79 moves out of contact with the lug 68 and the surface of this member contacts with the lug 67 to effect a return lateral movement of the feed bar 60 to bring the cloth back to its original position. This return movement is aided by the spring 82 which occupies a slightly diagonal position when the feed bar is moved to one side. The needle bar again descends and makes another stitch in the hole made by the piercer, completing the return side stitch and bringing the parts into position for a forward feeding movement and for a forward stitch. When the needle bar again descends and effects the third upward movement of the lever 47, the cam arm 58 rides out of contact with the part 59 and drops into the recess 56, thus releasing the piercer arm 47 and permitting it to be retracted by the spring 55. The lever 75 rides the high portion 81 of the cam 34 and moves the feed bar 60 to the right. To complete a hemstitching operation, the cloth has to be passed through the attachment twice, being turned end for end between the passages.
