Title: Apparatus for and method of manufacturing flexible containers
Inventor: BELL RAYMOND MILTON
IPC: B31B19/60
Filed: 1962-04-24
Abstract: 936,330. Paper bags. ELECTROLUX CORPORATION. April 24, 1962, No. 15608/62. Class 94(2). [Also in Group XXX] Before a sealing tape  134, Fig. 3, is applied to seal the ends of bags 76,  Fig. 11, carried on a conveyer with their ends directed to one side of the conveyer, the spacing between the bags is reduced so that, when the tape is subsequently cut between the bags, the wastage of tape is reduced. In the machine illustrated the closer spacing is effected by delivering the bags from a conveyer 94, 98, Fig. 2a, on to a slower pusher conveyer, 104, Fig. 1b. The bags are delivered to the slower conveyer  over a plate 126 formed with an inclined portion 128 which enables the bags to be overlapped, as indicated in Fig. 12, at their wider bottoms 52, Fig. 11. The tape 134 is fed through grooving rollers 138, Fig. 3, and over a glue-applying wheel 148 to a position between pressing rollers 154, 156 where it underlies the bags with one margin of the tape extending upwardly, as indicated in Fig. 29, adjacent the bottom edge 82 of the bag, to direct a stream of adhesive from a nozzle 158 into the opening of the bag. The tape is then folded over the end of the bag by folding rollers and guides 166, 160. A further stripe of adhesive 212, Fig. 19, is then added adjacent the tape and the tape end is folded over on to this by folding guides 216, 218. The bags, which are intended for use as dust bags in vacuum cleaners, have stiff cardboard ends 76, Fig. 11, carried by a pusher conveyer 60, Fig. 1a, under a glue-applying device 62, Fig. 2a, which prints a stripe 72, Fig. 25, of glue. The closure discs are then carried beneath a table 86, Fig. 1a, to which are delivered bags pushed by a conveyer 90 so that they register with the covers on to which they fall at the end of the table 86. The covers and bags are then pressed together by the conveyer 94, 98.

Title: Improvements in and relating to magneto electric machines
IPC: H02K21/26
Filed: 1921-06-07
Abstract: 164,344. Bosch Akt.-Ges., R. June 7, 1920, [Convention date]. Magneto - electric machines.-In a magneto, the axis of the magnet system is arranged parallel with the axis of rotation of the armature, and securing means may be used to give a wedging-action for drawing the magnet limbs on to the pole-pieces and the casing. In the form shown in sectional plan in Fig. 1, the limbs 5, 6 of the magnet 3 are fitted tightly in perforations in the laminated pole-pieces 4, which are secured, for example by casting or brazing, in the casing 1. Fig. 4 shows a section on the line EF of the form shown in Fig. 3 in which the magnet 3 with semi-circular limbs 5, 6 is mounted with its axis above that of the armature rotation. The limbs are forced into lateral contact by the pole-pieces 4 and drawn endwise on to the casing 1 by a cylindrical piece 7 and screw 8 bearing on the casing. The limbs may be formed at 9 so as to extend the surface of the pole-pieces. In an alternative arrangement, the pole-pieces are secured by a similar device in such a manner that the major part of their contact is made with the ends of the magnet limbs instead of their side surfaces as shown in Fig. 4, and when the pole-shces are laminated, the laminations are twisted through 90‹ so that at the armature they lie at right-angles to the axis of rotation and also stand vertically on the end faces of the magnets. In the form shown in Fig. 6, two bar magnets 5, 6 have a yoke 18 at one end and are forced by a wedge 7 and screw 8 at the other end into contact with the pole-pieces 4 and casing 1. In another form, the wedge is drawn towards the arch of a horseshoe magnet by a screw and nut bearing on a yoke-bar formed on the casing. Fig. 9 shows a form in which the magnet 3 and armature 2 are geared to rotate in opposite directions with respect to fixed polepieces 4 so as to give four sparks per revolution. The magnet has semicircular limbs surrounded by a sleeve 13 made of segments which may be wholly or partially formed of lamina; held together rigidly by non-magnetic pins secured in the end plate 14 and the magnet body. The sleeve may be alternatively pressed on to the magnet limbs or be otherwise secured. The Specification as open to inspection under Sect. 91 (3) (a) comprises also an arrangement in which a number of magnets lie with their axes parallel to the axis of rotation of the armature, the arms of similar polarity being fitted into perforations formed in the same pole-shoe. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the production of hydrochlorides of 2-aminothiazoles
IPC: C07D277/40
Filed: 1955-06-02
Abstract: A process for the production of a 2-aminothiazole hydrochloride comprises reacting a compound of formula <FORM:0769827/IV(b)/1> wherein n is 1 to 3 inclusive, with thiourea or an N-substituted thiourea having one of its amino groups unsubstituted at an elevated temperature in the presence of an acid catalyst. N-substituted thioureas include those substituted with alkyl, aryl, cycloalkyl and aralkyl groups, e.g. methyl, ethyl, unsym.-dimethyl, unsym.-diethyl, tertiary-butyl, n-butyl, phenyl, unsym-. methylphenyl, para-methoxyphenyl and para-bromophenyl thioureas.  The acid catalyst may comprise an aqueous solution of a strong mineral acid present in an amount between 0.1 and 5 per cent based on the weight of the reactants, and is preferably aqueous hydrochloric acid of 5-37 per cent strength.  The 2-aminothiazole hydrochlorides are preferably isolated by adding to the reaction mixture (before or after completion of the reaction) a glycol-miscible organic liquid that is substantially a non-solvent for the resulting 2-aminothiazole hydrochloride, cooling the reaction mixture to a temperature of 0 DEG to -50 DEG  C. and separating the solid product which precipitates. The glycol-immiscible organic liquid is preferably added in an amount equal to half to twice the volume of the reaction mixture and is preferably acetone, methylethyl ketone or methyl, ethyl, propyl or isopropyl alcohol.  The 2-aminothiazole hydrochlorides may be neutralized to give the corresponding free bases.  The glycol by-products may be isolated and reacted with a  : b -dichloroethyl ethers to give chloromethylated cyclic glycol ether starting materials according to the process of Specification 758,425.  In examples, thiourea is reacted with (1) 2-chloromethyl-1 : 3-dioxolane and (2) 2-chloromethyl-1 : 3 : 6-trioxocane to give in both cases 2-aminothiazole hydrochloride.
