Title: Improvements in or relating to the production of articles on straight bar knitting machines
Inventor: MATTHEWS DENIS
IPC: D04B11/22
Filed: 1959-04-02
Abstract: 945,472. Knitting. MATTHEWS & BIRKHAMSHAW Ltd. July 4, 1960 [April 2, 1959], No. 11147/59. Headings D1C and D1K. Tuck fabric is produced on a straight-bar machine by recessing, as at 5, the normal presser edge 4 of the sinker head 3 so that alternate needles fail to press. A tricked auxiliary presser member 6 is positioned beneath the sinker head and is advanced during alternate courses so as to engage all of the needles and to cause them to press. Consequently alternate needles produce a sequence of tuck loops. The member 6 is advanced by providing a bar 11 which is moved longitudinally to cause a cam portion 12 to advance the member 6 whilst a spring 13 serves to return the member when the bar is moved into its initial position. In an alternative arrangement the auxiliary presser member is constructed to engage only the alternate needles so that when the member is advanced beyond the normal presser edge, and simultaneously the needles receive a modified motion, only these auxiliary needles press. When the auxiliary presser member has its presser surfaces aligned with the normal presser edge and the needles function normally, then all of the needles press, whereas when the auxiliary presser is retracted behind the presser edge and the needles function normally only the intermediate needles press. Consequently tuck loop sequence in alternate courses and wales can be produced.

Abstract: 392,346. Bending bars. RICHARDS, F., 14, Brynheulog Street, Port Talbot, Glamorgan. April 19, 1932, No. 11171. [Classes 83 (ii) and 83 (iv).] Bars 19, particularly for forming half-sections of arches for use in mines, are worked in a machine comprising a roller bending unit 3, a guide 7 for the curved bar, a unit 6 comprising press members 14, 15 for shaping the end of the bar to form the crown of the arch, and a circular saw for cropping the end-piece from the bar in order that the curved bars may mate accurately when assembled. The bending unit may be angularly adjusted and the shaping unit 6 may be diagonally adjusted along slots 2 in the bed-plate 1. The bending rollers are flanged and the roller 11 is mounted in a housing which carries a cover-plate 12 extending over the bar and which may be radially adjusted by an hydraulic ram or by screw gear. The bending rolls are gear driven and may be intergeared. The guide 7 is selected to suit the particular curve to which the bar is bent and is bolted to the curving and shaping units. The bar travels till arrested by a stop 17 whereupon a die 15 is actuated by a fluidpressure cylinder 23 to shape the bar end in conjunction with a fixed die 14. A powerdriven circular saw 5, mounted on the casting 6, is advanced to sever the bar end projecting from the shaping dies. When profiled bars having one flange narrower than the other are employed, horns 20, Fig. 2, are provided on the die 15 to avoid distortion during shaping. Specification 338,451, [Class 20 (ii), Buildings and structures, Miscellaneous accessories &c.], is referred to.

Title: Manufacture of aliphatic dinitro compounds
IPC: C07C205/29
Filed: 1943-12-11
Abstract: 1 : 3-Dinitropropanes of a general formula RRIC(NO2)-CRIIRIII-CHRIVNO2, where R, RI, RII, RIII and RIV may be hydrogen or straight chain, saturated aliphatic hydrocarbon radicals of not more than 2 carbon atoms, the same or different and where RII or RIII and RIV may together form part of a cycloaliphatic ring and where R and RI may bear as substituents the groups -O Alkyl or -S alkyl, are prepared by heating a compound of general formula RRICHNO2 with an olefine of general formula RIIRIIIC=CRIVNO2\t in the presence of a basic substance.  This may be effected in a solvent such as ethanol, ether or pyridine.  The reaction mixture is neutralized with acid and the product purified by distillation.  In the examples: (1) 2-nitropropane is condensed with 2-nitro-2-butene, which is made by heating 3-nitro-2-butyl acetate with sodium acetate, in the presence of sodium dissolved in ethanol.  The product may be treated with diazotised p-nitroaniline to give an azo compound; (2) 2-nitro-2-butene is condensed with nitroethane in the presence of dioxan and benzyltrimethyl-ammonium hydroxide; (3) 2-nitro-1-methoxypropane is condensed with 2-nitropropylene in sodium dissolved in methanol.  The products of the foregoing examples are brommated to yield bromo derivatives; (4) methyl-2-nitropropyl sulphide is condensed with 2-nitropropylene in a solution of sodium in methanol; (5) 2-nitro-propene is added to a solution of sodium methoxide.  Part of the 2-nitropropene is converted to 1-methoxy-2-nitropropane which then reacts with unchanged 2-nitropropene; (6) 1-nitro-2-methyl-1-propene is condensed with nitromethane in piperidine; (7) 2-nitropropane is condensed with 2-nitropropene in a solution of sodium in ethanol. Other nitroparaffins, nitroethers or nitrothioethers which may be used in the reaction are 1-nitropropane, 2-nitro-3-methoxybutane and methyl-2-nitro-1-methylpropyl sulphide.  Other olefins which may be used are 1-nitropropene and 1-nitrocyclohexene.  The products may be used as intermediates in the manufacture of dyestuffs and pharmaceutical chemicals.  Specifications 573,872, 584,792 and 584,793 are referred to.

Abstract: 352,501. Alternating-current commutator machines. HOLMES & CO., Ltd., J. H., North Drive, Hebburn-on-Tyne, and MARDEN, W., 4, Northumberland Avenue, Forest Hall, Northumberland. April 10, 1930, Nos. 11394 and 38830. [Class 35.] Windings.-The stator of a polyphase commutator motor is wound with full pitch coils and the winding of each phase is in two parts, the part of each phase which is leading in space with respect to the direction of field rotation carrying a current which is lagging in phase with respect to the current carried by the other part for the purpose of improving the commutation. According to one arrangement, Fig. 1, the leading parts A<2>, B<2>, C<2> are connected in mesh and the lagging parts A<1>, B<1>, C<1> in star with their inner ends connected to the mesh junction points. Accordingly the current in a leading part such as A<2> lags in phase by 30‹ with respect to the current in the part A<1>. In a modification, Fig. 2, which has the advantage of not altering the magnitudes of the currents in the two parts of each phase, a leading part such as A<2> of phase A is connected to the phase A supply terminal in series with the lagging part C<1> of phase C reversely connected. The current in a lagging part such as A<1> therefore leads the current in the part A<2> by 60‹. Polar diagrams and diagrams showing instantaneous directions of the stator currents are given for the purpose of explaining how a commutating field is produced to neutralize the transformer voltage set up in a short-circuited coil.
