Patent GB-190121874-A (GB)
Title: Improvements in the Manufacture of Aromatic Hydrocarbons and in Apparatus therefor.
Inventor: NIKIFOROFF ALEXANDER
Filed: 1901-10-30
Granted: 1902-10-30
Abstract: 21,874. Nikiforoff, A. Oct. 30. Anthracene; benzene and its homologues; hydrocarbons; naphthalene. - Aromatic hydrocarbons, such as benzene, toluene, xylene, pseudocumene, naphthalene, and anthracene, are produced from naphtha (crude petroleum), naphtha residues, heavy oils resulting from the distillation of bitumen, coal, and the like, and from bitumens resulting from the manufacture of naphtha gas, by acting upon these substances at a high temperature under pressure. The process is carried out in two stages :-(1) The material is heated at about 525‹ C. in retorts 1, Fig. 2, in which are troughs 2 provided with alternating transverse baffle-plates for retarding the movement of the naphtha along them. The distillates and gases pass through a water tank 4, and thence by a pipe 5 to perforated tubes in a separating-chamber 3, in which they are thoroughly washed, for removing compounds which have boiling points above 200‹ C. The uncondensed compounds pass to a cooler, and thence to a controlling-apparatus 9, Fig. 12, from which the gases pass by a pipe 12 to a gasometer, while the liquid flows out at 13. This apparatus has a gauge glass 10, containing a hydrometer by which the density of the distillate may be observed. (2) The liquids, boiling below 200‹ C., which are thus obtained, are further heated under pressure up to about 900‹ C. in retorts 14, Fig. 3, arranged in two or three series, to which they are supplied in a heated condition by preliminary retorts 15. The pressure in the retorts is increased by causing the gases from them to pass through an aperture in a disc 17 fixed in the exit pipe and adjustable by a needle 26. The retorts and their connecting-parts are fitted with scrapers consisting of discs provided with teeth and mounted upon stems 20. From the retorts 14 the vapours pass through a receiver, Fig. 6, fitted with an agitator 24, so that the gaseous products are thoroughly washed in the tar collecting therein, and thence they pass to a gasometer or to washers or absorption apparatus. Naphtha or its distillates may be employed as absorbers, but preferably methyl alcohol, acetone, or the like is used, and the product is extracted by water. The hydrocarbons of boiling points above 200‹ C. are decomposed in vertical retorts at a higher temperature. The process is also applicable to solid bodies, which are for this purpose, fused with aromatic tar of high boiling-point to prevent solidification at ordinary temperatures.

Patent GB-190303572-A (GB)
Title: An Improved Electrical Measuring Instrument
Inventor: GROVES WELLINGTON ERNEST
Filed: 1903-02-16
Granted: 1904-01-07
Abstract: 3572. Groves, W. E. Feb. 16. Current, energy, and resistance meters. - An ampÞre-meter A and a volt-meter V with central zeros are mounted so that their pointers a', v<1> cross over a plate which is marked with curves o' indicating resistance, or with curves at rightangles thereto, indicating power, suitable electric connections being made, and readings taken at the point where the pointers cross one another. Both sets of curves may be marked on the plate, together with ordinary scales a, v indicating current and pressure. The Provisional Specification mentions that recording-mechanism may be attached to the instrument. Testing.-For measuring the insulation-resistance of a three-wire distribution system during working, the resistance meter described above has the ampÞre scale a on a strip carried by two pins g above the ampÞre pointer a<1> and the curve plate ; the pins slide through the plate, and are connected by a cross-piece to the armature lever of an electromagnet E, so that, when this is excited, the strip a clamps the ampÞre pointer a<1> against the plate. The ampere-meter A is in circuit with a switch S, which normally is held closed by springs. Two springs C, in a circuit containing the electromagnet E, are held apart by the switch S when this is closed, but make contact and close the circuit of the electromagnet E when the switch is opened, before the circuit of the ampÞre-meter A is opened. The ampÞre pointer a<1> is thus clamped in its deflected position. The ampÞre-meter A and switch S are connected in series with a known resistance between the "neutral" conductor and the earth ; the pressure meter V is connected directly between the "neutral" conductor and earth, and the reading is made at the point of intersection of the two pointers a', v<1> after the switch S is opened. The pointer of the voltmeter may also be clamped as described. The resistance read includes the resistance in series with the ampÞre-meter, but this may be allowed for in marking the curves.

Title: Improvements in Knitting Machines.
Filed: 1903-04-14
Granted: 1904-04-14
Abstract: 8424. Sowter, G., James, W. I., and Dorman & Co., W. H. April 14. Circular knitting - machines.-The machine is adapted to form flat, fashioned orunfashioned, web byreciprocation only. The needles are arranged i n two series, each operated on by its own cams and feeders. Normally, the needles are all out of action, their butts lying below the level of the ordinary cam grooves. The needles are lifted within range of their cams by separate jacks acted on by quadrant lifting- plates of the same nature, and operated in the same manner, as those described in Specifications No. 5648, A.D. 1896, and No. 10,493, A.D. 1894. When one set of cams passes over the other set of needles, the latter are out of action. The jacks which act on the two needles at the junction of the two sets are provided with butts, which are operated on by levers and cams, and caused to raise the needles above the point of the cam h, Fig. 2, with the result that the yarn knitted on one series of the needles is wrapped round the first needle of the next set, which needle, at the next passage of its own cam, draws its old loop through two new loops, the two halves of the fabric being thus joined together. In narrowing, the quadrant lifting-plates are racked inwards step by step in the manner described in the above-mentioned Specifications. The needles, which automatically go out of action as the lifting-plates are racked, are first raised by butted jacks, cams, and levers on to the cam h<2>, which raises them sufficiently high to prevent them from taking yarn into their hooks, thus ensuring the casting off of the old loops. In widening, the slides are racked outwards step by step. By means of a rocking thread-carrier, shown in Fig. 5, operated by a sliding rod p and a cam q<1>, the splicing-thread may be passed to the back of the needles at any part of the cylinder, so as to prevent the splicing-thread from knitting.

Cooling and ventilating.-Relates to arrangements of casings &c. for dynamo-electric machines to facilitate the circulation of cooling-currents of air over parts liable to heat. In one form, the casing consists of two caps H, Fig. 1, which are drawn against the stationary parts B, or it might be the rotating parts B', by staybolts S, leaving a circumferential opening L or a series of openings between abutting projections on the edges of the caps. The casing may otherwise be built up of parts jointed together parallel to the armature shaft A. The opening L may be covered with wire netting &c. The air currents are drawn through the casing from the central end openings 0 to the opening L, or vice versÔ, by the special arrangement of the rotating coils or by vanes &c. on the rotating parts ; in their passage the currents cool the sides f of the rotating part B', the coils W<1> of this part and those W of the stationary part B, and the sides and outer surface of the part B. The casing may be of sheet iron, or may be cast with the feet or base of the machine and with the bearings of the armature. In some cases, the windings of the active parts may be separated by insulators to form openings for the circulation of the air. In the arrangement shown in Fig. 4, the casing H supports the shaft A and the part B, the bolts S being passed through holes in lugs on the plates of the part B, and provided with clamping-nuts and washers. A method of securing the plates of the part B' in short-circuit motors consists in clamping them between conducting-rings k which are slotted at the centre and are held on the shaft by means of rings r<1>. Ribs may be formed on the magnetic bodies, and air passages may be provided between the cores and windings by making the cores angular and the windings round, or vice versÔ.
