Title: Improvements in and relating to Bleaching Fibres Fabrics or the like.
Inventor: BLOXAM ARTHUR GEORGE
Filed: 1907-07-01
Granted: 1908-05-21
Abstract: 1 5 , 1 3 7 . Bloxam, A. G., [Kirchhoff & Neirath]. July 1. Bleaching.-Magnesium perborate is used for bleaching vegetable fibres or fabrics, such as cotton, jute, linen, and ramie. The perborate may be itself added to the bleaching-bath or prepared therein, for example by adding a solid alkali perborate and a magnesium salt or by adding boric acid, or an alkali borate, followed by a magnesium salt, to an alkaline liquor containing hydrogen peroxide or alkali peroxide. In an example, cotton yarn, wound or loose, previously treated as usual with alkali, is charged into a pressure boiler with good circulating means. A mixture is added consisting of caustic soda and soap, or turkey-red oil, or castor-oil soap, with hydrogen or sodium peroxide, boric acid, and magnesium chloride, or with sodium perborate and magnesium chloride, or with magnesium perborate, all with sufficient water. The boiler is closed and the temperature raised by steambeating until the pressure is about one and a half atmospheres, the boiling being continued for three to four hours. After cooling and blowing off the steam and liquor, the goods are washed with water in the boiler, removed, washed, and treated with dilute sulphuric acid, washed, and dried. A repetition of the treatment is occasionally necessary. Linen and jute require milder alkalis than cotton and ramie, for example sodium carbonate, and the boiling is done at ordinary pressure. According to the Provisional Specification, other peroxidized bodies may be used in addition to magnesium perborate, for example the paroxides, percarbonates, and persulpbates of aluminium, magnesium, and zinc, and the perborates of aluminium and zinc; hydrogen peroxide and magnesia may also be used in the presence of caustic soda and soap.

Granted: 1908-08-06
Abstract: 18,097. Wallis, S. A. Aug. 9. Jacquards.-Easily removable and exchangeable packing-pieces d, e, f, g, h are employed to effect a rapid readjustment of the bars selected by a jacquard dropper, should this be rendered desirable by a change in the pattern of work to be made. For facility in manipulation, these pieces are made U-shape in cross-section, with perforated lugs k. The thickness of the piece d is equal to one gait or division, the other pieces e, f, g, h being multiples thereof. The pieces may be mounted on the drawbits b between the adjusting-screws c and the abutments i of the dropper boxes or slides. The thrust of the screws is received by plain piecesj, which protect the packing-pieces proper from wear. In another form, the draw-bit is halved, the halves being placed side by side, and the packing-pieces are inserted between abutments formed by the enlarged ends of the half-bars. In another form a similar construction is applied to an auxiliary har connecting the draw-bit to the selected bar, and in a fourth form one half-bar is superimposed on the other.

Title: Improved Methods of and Means for Conducting Gaseous Endothermic Reactions
Inventor: FERRANTI SEBASTIAN ZIANI DE
IPC: H01J37/32
Filed: 1907-09-17
Granted: 1908-09-17
Abstract: 20,697. Ferranti, S. Z. de. Sept. 17. Gases, treating electrically; gases, obtaining in; nitrogen oxides.-In conducting endothermic gaseous reactions, for example by the electric arc or a resistance heater, or by internal combustion, the gases are quickly cooled by expansion through one or more nozzles. The escaping gases may have their kinetic energy absorbed in a rotating wheel system, or they may be treated with cooling surfaces or sprays. The invention is particularly applicable to the fixation of nitrogen in air, furnace gases, &c., in which case the nitrogen oxides formed may be converted into nitrates or nitrites. An arrangement of plant is shown in Fig. 9, comprising a multi-stage turbo-compressor n having intermediate coolers o, which forces the gases into the arc-chamber h. The gases pass through an expansion-nozzle ! i into a wheel system u in connexion with an expansion chamber v and turbocompressor w. The parts are preferably arranged on a common shaft driven by a motor z. In the form of arc-chamber shown in Fig. 1, an annular arc is struck between a circular electrode a and an annular electrode b, and rotated by a coil c. Passages for the circulation of cooling-liquid are formed in the electrodes. In a modification the coil is external to the electrode b. The current may be continuous or alternating ; in the latter case, means must be provided to put the arc and field in phase unless a continuous field is used, when the arc rotates backwards and forwards. The field may be dispensed with and the arc struck between parallel electrodes, an arrangement of carbons suitable for three-phase working being shown in Fig. 3<b>. In the form shown in Fig. 4, the arc is blown along diverging electrodes p by a current of gas from the pipe d. The gases may be heated by a resistance heater of the Nernst type shown at r, Fig. 8, and they may be afterwards passed through the arc y. Preliminary heating of the resistance r may be effected by the combustion in the gases of a suitable fuel, for example acetylene or hydrogen, and oxygen, fed through nozzles t, and in some cases this internal combustion is sufficient to effect the reaction.

Abstract: 1950. Kingsbury, J. E., [Bell Telephone Manufacturing Co.]. Jan. 28. Switches.-Gravity switches, such as are used with telephones where the switch contacts are separated when the receiver or other weight is hung on the lever-arm, are constructed so that the lever-arm or switch-hook a, which is to project from the outer case or stand containing the switch contacts &c., is made removable in such a way that when the case or stand is closed it can, without the use of tools, be inserted into place and made to engage permanently with the switch mechanism &c., and cannot be withdrawn unless the case is opened to release it. A support d formed of a strip of sheet metal has side portions d<1>. It carries vertical spring contacts b, a pivot c for the lever or hook a, and stops which limit the movement of the arm. On the pivot c is mounted a rocking frame e having parallel side walls between which the arm a passes. A rectangular slotis cut in the strip d through which the arm passes, and the side walls of the frame e project through the slot for a short distance. The end of the arm a is slotted to engage the pivot c, and rests on the lower part of the frame e, where it is held by a catch consisting, in the form shown, of a slot i with which the rocking frame engages. On the rocking frame e is an ebonite roller h, which is held away from the switch contacts b by a spring g when the telephone &c. is off the hook, but opens the contacts when the telephone &c. is replaced. When the case is open, the frame e may be rocked by a thumb-piece lc to release the switch arm. The outer end of the lever a may be forked to support the telephone receiver, in which case the switch arm or lever may be put in place with either side uppermost. When the arm is hooked, as shown in Fig. 5, means are provided to ensure that the lever is inserted with the hooked end upwards ; this may be done by making the pivot slot f in the lever end inclined to the stem.
