Patent GB-716239-A (GB)
Title: Improvements in and relating to the production of amines
Inventor: WARD STANLEY
Filed: 1951-01-22
Abstract: The invention comprises a process for the preparation of N-alkylated aromatic amines by reaction of an aromatic amino-, nitro- or nitroamino-compound with a di-alkyl ketone containing at least four carbon atoms, and hydrogen, characterized in that there is recycled to the feed an aqueous distillation cut from the final product comprising the water/ketone azeotrope.  The reductive alkylation is conducted at elevated temperature and preferably under pressure using a hydrogenation catalyst, and is particularly applicable for preparing N : N1-di-alkyl phenylene diamines.  In examples: (1) p-nitraniline is dissolved in methyl ethyl ketone/water azeotrope, water layer separated and other layer pressure hydrogenated using palladium catalyst to yield N : N1-di-sec.-butyl-p-phenylene diamine; (2) the organic layer as in (1) is treated with recycled material and passed with hydrogen over copper chromite under pressure.  The product upon distillation yields N : N1 - di - sec. - butyl p - phenylene diamine.  m-Dinitrobenzene and p-phenylenediamine are also specified as starting materials.  Specifications 621,749 and 712,100 are referred to.

Abstract: 309,939. Haswell, A., J., and Waygood- Otis, Ltd. Jan. 18, 1928. Casings, frames, and foundations; protective or safety devices, auxiliary.-To prevent interference with wireless installations by the operation of a motor or other dynamo-electric machine, the machine frame or carcass is insulated from earth and is connected in closed circuit with the brushes through a capacity. Means are also provided for automatically earthing the frame when the machine is not working or is under inspection. In the form shown, which illustrates the application to a lift motor, the motor carcass F is insulated from the coupling and from its bedplate B by means of insulating material and the brushes are connected to two banks of condensers C<1>, C<2> in series, the other pole L<2> of which is connected to the framing at L<3> optionally through another condenser C<3>. The condensers C<1>. C <2> are supported by an insulating block D and a high resistance R may be bridged across the brushes to act as a damping resistance or to minimize the effect of commutator ripple. The capacities are so chosen that the oscillations in the closed circuit are of a frequency not audible in the receiving set. A switch S is provided for earthing the frame during inspection of the motor and this may be arranged in conjunction with the lighting switch of the motor compartment, or it may be operated by the door so that the frame is earthed when the door is opened or the light switched on. Alternatively, the earthing switch S may be actuated by or in conjunction with the control switch on the motor board, or by means of a relay in one of the control circuits of the installation so arranged as to cut in the damping arrangement when the lift is started up and drop back on two contacts to earth the motor frame when the lift is at rest.

Abstract: 764,458. Inserts for boxes. FROBENIUS AKT.-GES. Jan. 26, 1955 [Feb. 10, 1954], No. 2359/55. Class 18. A box insert is formed from paper &c. strip by slitting the strip longitudinally at spaced intervals to define a middle and two side zones, the side zones being divided into separate flaps by transverse cuts or slots, folding the middle zone to produce compartments separated by the folds, and overlapping the flaps tile fashion and securing them together. The sides of the folds may be cut to give flaps 10, 11 which are displaced by the contents such as ampoules 12, and the side zones may be folded to close the compartment ends. Tongues 9a, b, c may be formed in the flaps 8 to coincide when these overlap and be pushed up to connect the respective flaps together. The inserts may be formed from a pre-cut continuous web by apparatus comprising fixed and moveable die elements 17, 18 respectively, a co-operating punch 20 and a feeding device 25. The web is fed forward intermittently the unfolded length of a fold 5 by dogs 26-28 on the device 25, the latter dropping after each feeding movement (vide arrow 36, Fig. 6). During feeding, the element 18 remains against the previously formed fold 5 and as the punch 20 rises under the web, following the path 33, it travels towards the element 17 exerting tension on the web. Members 29 press downwardly the trailing edges of flaps 8 to assist overlapping and finally the elements 17, 18 come together to press the fold 5 about the punch 20. The formed portion of the insert is drawn rearwards during folding. Where, as shown, tongues 9a, b, c, unite the flaps 8, plungers 21 force up the tongues into recesses 23 in abutments 22 on the element 17. The device 25 has meanwhile re-engaged the folds (vide arrow 34) and a new feeding movement commences. Movement of the element 18 is shown by arrows 35, 37, 38, Fig. 6.

Abstract: 1,208,063. Cigar manufacture. MOLINS MACHINE CO. Ltd. and A. J. KEIZER. 14 Jan., 1969 [16 Jan., 1968], No. 2433/68. Heading A2C. Rods of cigar-tobacco are formed by passing a filler consisting of pieces of cigar tobacco lengthwise on a wrapper to a first compression device and then passing the partially compressed filler from this device to a second compression device which device has an entrance wider and higher than the exit of the first device whereby the partially compressed filler can suddenly expand on entering the second compression device. The process may be carried out in an apparatus as shown in Fig. 1 wherein pieces of leaf are carried on the underside of a suction conveyer 1. A tape 4 carries a continuous wrapper web 5 beneath the band 1 and wheel 3 so that the filler is released on to the web 5. The tape 4 runs in a trough (Figs. 2-6, not shown). The filler is then passed beneath the shoe 6 and into a channel, the walls of which, 7, gradually extend downwards towards the trough. The channel becomes progressively narrower, thus partially compressing the filler. This filler is then passed beneath the compression tongue 8. The tongue at its entry is wider and higher than the exit of the channel in shoe 6. In passing from the shoe 6 to beneath the tongue 8, the filler may expand. The web is folded over the compressed filler during the passage of the filler beneath the tongue 8.
