Granted: 1902-09-25
Abstract: 7950. Bier, J. M., and Bier, G. April 4. Bobbin holders.-Relates to sticky fly-catchers, and consists in means for ensuring that the string or the like shall be properly coated with composition. The Specification describes several forms of the device. In one form, the band to be coated is coiled within a reel, composed of a bent strip of metal, the ends of which extend vertically downwards to form a guide, and are then bent upwards near the sloping sides of the container, to occupy the position of the plates c, Fig. 1, which represents a form of the device in which the reel and guide are not used. The guide is perforated, and composition is forced through it on to the band, when cords, such as d, fixed to the tops of the upwardly bent parts are pulled. These cords pass through guides on the outer surface of the reel and are adapted to support the device. In another form, several bands pass from reels through the container, which is made of thin metal, so that its walls can be pressed inwards to cause the adhesive to press on the bands.

Granted: 1903-04-09
Abstract: 12,444. Newton, H. E., [Farbenfabriken vorm. F. Bayer & Co.]. May 31. Alkylindole-sulphonic acids, which contain the sulpbonic groups in the benzene nucleus, are produced by acting with sulphonating-agents upon indole derivatives, such as alpha-methylindole (Pr 2-methylindole), B3: Pr 2-dimethyliodole, B3- chloro - Pr2-methylindole, B3-methyl-Pr1<n>-ethyl 2-methylindole, Pr 1<n> : 2-dimethylindole, B3 : Pr 1<n> : 2-trimethylindole, Pr 1<n>-ethyl-2-methylindole, B3-methyl-Pr1<n>-ethyl-2 - methylindole, and the like. An example is given in which Pr 2-methylindole is stirred into sulphuric monohydrate, and to the cooled mixture fuming sulphuric acid containing 20 per cent. of SO3 is slowly run in, while the temperature is prevented from rising above about 60‹ C. The sulphuric acid is then separated in the form of its barium or calcium salt. The B3-methyl-Pr1<n>-ethyl-2-methylindole employed is obtained by Fischer's method, using acetone and a symmetrical ethyt-p-tolythydrazine, and the B3 : Pr 1<n>: 2-trimethylindole is similarly obtained from acetone and a symmetrical methylp-tolylhydrazine. Dyes, artificial.-Azo dyes are produced by combining the foregoing alkylindole-sulphonic acids with aromatic diazu compounds, or by combining the alkylindoles themselves, which are not substituted in the Pr 3 position, such as B3 : Pr 2- dimethylindole, B3-chloro-Pr2-methylindole, or their derivatives alkylated in the imido group, or the like, with diazo compounds containing sulphonic groups. Examples are given in which greenish-yellow dyes for wool are obtained from diazotized p-sulphanilic acid and Pr 2-methylindole, and from diazobenzene and Pr 2-methylindole sulphonic acid. Other diazo compounds of the benzene and naphthalene series, or diazoazo compounds, tetrazo compounds or the like, yield orange to brown clear and fast dyes. Dye-stuffs are also produced by condensing the alkylindole solphonic acids with p-diamidobenzophenone, its alkylated derivatives, or the corresponding auramines or thioketones.

Granted: 1903-08-27
Abstract: 25,242. Johnson, J. Y., [Badische Anilin & Soda Fabrik]. Nov. 17. Barium, calcium, potassium, sodium, strontium, &c. oxides.-Relates to the manufacture of potassium oxide alone or mixed with sodium oxide or other alkali oxide or alkaline-earth oxide, or, generally, to the manufacture of mixtures of such oxides. A nitrate or nitrite is decomposed by metallic potassium or sodium, or an alloy of those metals, in accordance with the following equations- The nitrate or nitrite should be introduced into the molten metal, care being taken to exclude air, or the metal may be introduced into the molten salt. To obtain a mixture of potassium oxide and sodium oxide, sodium nitrate or nitrite is decomposed by potassium, with or without the addition of potassium nitrate or nitrite. Or potassium nitrate or nitrite, mixed or not with other nitrate or nitrite, may be acted on by sodium. Similarly calcium, barium, or strontium nitrates or nitrites can be decomposed by sodium to produce mixtures of oxides. To lessen the violence of the reactions, they may be carried out in the presence of a diluent, such as an anhydrous caustic alkali.
Patent GB-190227676-A (GB)
Title: An Improved Form of Hydraulic Press for Assembling the Parts of Electrical Commutators, Tightening the Ends of Electrical Commutators and Pressing Together the Discs of Electrical Armatures.
Inventor: PETCH ALBANY FRANCIS
Filed: 1902-12-16
Granted: 1903-12-10
Abstract: 27,676. Petch, A. F. Dec. 16. Armatures; commutators.-A hydraulic press for use in assembling the parts of electric commutators, tightening the ends o commutators, and pressing together the discs of armatures consists of a fixed differential ram B on a base A, and a movable cylinder C, to the interior o f which pressure water is admitted through an inlet F. In assembling a commutator, the parts G are arranged upon a hollow block L resting on the upper flat end of the cylinder and having its internal surface tapered outwards at the top. The upward pressure is resisted by a block H which bears against a nut K on a bolt E screwed into the ram B, so that the block L is forced over the commutator as the cylinder C rises. The projecting commutator ends can then be machined to fit the end plates. These plates may be tightened and the finished commutator withdrawn from the block L, which is then suitably propped up, in the press. In the case of small commutators through which the head of the ram cannot pass, a stool is used to raise the block L to the level of the bolt E. In a modification, the ram is movable and the cylinder stationary. In this case, an ordinary crank-pin or wheel press has a bolt inserted through the back of the stationary cylinder into the ram, to act both as the smaller portion of the ram and as the bolt E shown in Fig. 2, when the press is used for assembling commutators. The press may also be used in the ordinary manner for forcing armatures, flywheels, &c. on to their shafts. The presses may be arranged at any inclination, weights &c. being provided for returning the rams.

Title: Improvements in Electric Metering Systems.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1903-03-27
Granted: 1904-03-10
Abstract: 7142. Carolan, E. A., [General Electric Co.]. March 27. Energy meters.- A reversible meter is provided with two counters, either of which may be driven from the meter spindle by friction clutches shifted electromagnetically in accordance with the direction of flow of energy in the meter circuit. Energy supplied in each direction is thus registered separately. For this purpose, the clutches are moved by two electromagnets, to either of which a current is supplied by a two-way relay in the main circuit. The invention is described as applied to a three-phase alternating- current three-wire system, two single-current motor meters being connected to two of the mains, with pressure connections to the third main, by means of four transformers. The three-phase relay, Fig. 10, is a rotary induction apparatus with four current and pressure coils 58, 61 connected to the four transformers, to cause turning of a conductive disc 38 and axle 37 through 180‹, limited by stops 45 ; the axle carries a contact arm to 'touch either of two stationary springs, and thus supply a current to either controlling-magnet, in each meter. In each meter the two controlling- electromagnets are of horse-shoe form, and act oppositely on two armature levers connected by a link, which carries pins to shift a lever controlling the clutches. The link also carries contacts to open the circuit of either electromagnet when it has effected the movement, and to connect in circuit either of two starting coils, in accordance with the corresponding direction of rotation of the meter. The clutch-controlling lever acts through a sliding rod 11, Fig. 5, and levers 12, 13, on the sliding halves 25 of two clutches, to withdraw these from loose wheels 22, 27 against the pressure of springs 20. The wheels 22, 27 gear with pinions on a shaft 23, which is revolved by the meter spindle. The sliding halves 25 are carried by two shafts 19, 28, which are geared to the two counters, so that, when either spring 20 is allowed to close its clutch, the corresponding shaft 19 or 28 is driven, with its counter.
Patent GB-190307387-A (GB)
Title: Improvements in or relating to the Standards and Supporting Devices of the Trolley or Current Collecting Poles of Electric Vehicles.
Inventor: TURNER WILLIAM HERBERT
Filed: 1903-03-30
Granted: 1904-03-17
Abstract: 7387. Turner, W. H., and Isherwood, W. H. March 30. Collectors.-Relates to the] standards and supporting-devices of the trolley or current-collecting poles of electric vehicles, and comprises means for preventing the pole from swinging upwards when the trolley accidentally leaves the overhead wire. Figs. 1 and 2 show one form of the invention as applied to a standard a having an internal spring f. The hollow tension-rod b, through which passes the cable k, is fitted at the end with a sleeve c sliding on a feather key and containing a buffer spring 4. This collar is grooved at h and engaged by grooved or toothed wedges i connected by rods r to the armature p, which is normally attracted to the casting m by the coils n in the groove o preferably arranged in shunt with the main circuit. If the trolley leaves the wire, the armature drops under the action of the springs g, and draws the wedges down the inclines l into engagement with the sleeve c, thus preventing the trolley pole from rising. To allow the trolley pole to fall below the level of the overhead equipment, two discs t, y are fitted below the sleeve c. The disc t has slots j, h to receive wings z on the disc y, but it is normally held by a spring x so that they are out of alignment. When the pole is suddenly stopped from rising by the gripping-blocks i, the pressure and friction between the discs t, y is relieved and the spring x turns the disc t and brings the slots and wings into alignment, thus allowing the tension rod b to move upwards and the trolley pole to fall. Special devices may be provided for resetting the pole. The disc t may be turned back, after the disc y has been lowered out of engagement therewith, by means of bevel gearing, and the gripping-blocks i may be moved out of engagement with the sleeve c, by rotating inclined slides making contact with pins on the armature p. In a modified form of apparatus for narrow standards, a long sleeve is fitted with a serrated end piece engaged by gripping-blocks pivoted to a plate arranged above the core of a solenoid and having outer inclined faces, which work in conjunction with fixed inclined surfaces. The two discs t, y are replaced by wings on the end of the tension rod b and a slotted thimble placed concentrically between the ends of the rod b and sleeve c. Fig. 6 shows an arrangement for roofed cars ; the trolley pole 32 is carried by a pivoted angle-piece acted on by springs 34 and connected to a bar 36, the forked end of which slides in grooves 41. To this bar is pivoted a block 37 having a tooth 39 for engaging the rack 40, which block is normally held against the cover 38 by the action of the coils 43. If the trolley leaves the wire, the block 37 falls and the tooth 39 engages the rack 40, thus preventing the trolley pole from rising and damaging the overhead equipment.

Title: Improvements in Apparatus for Delivery and Production of Measured Quantities of Aerated Water.
Inventor: LEE WILLIAM
Filed: 1903-07-17
Granted: 1904-06-02
Abstract: 15,856. Lee, W., and McMurray, W. A. July 17. Measured quantities, delivering.-An aeratingapparatus contains a single valve, which has several ports or ways, and which, in two different positions, controls both the production and delivery of a measured quantity of aÙrated water. Cross-sections of the valve c, Fig. 3, at different points are shown in Figs. 4 to 8. In one position of the valve, gas is forced into the central vessel b containing a known charge of water, through the passages p, p<1>, Fig. 7, and water in a saturated condition is forced through the check valve i and perforated plates k<1> into the larger reservoir a. At the same time, the aÙrated water in the inverted bottle f, of known capacity, and having its neck e fitting tightly into a washer g<1>, flows through the openings m, m', Fig. 4, into the outlet pipe h<1>, and air is admitted into the top of the bottle f through the channel n<1>, Fig. 5, and the tube n. When the valve is turned through a right-angle, the bottle f is in communication through the channels m, Fig. 4, and the long tube q with the reservoir a, in which the water is under the pressure of the gas owing to the previous operation since no water or gas can flow back through the valve i. The water is thus forced up into the bottle f, which it fills, and, at the same time, water is flowing from a reservoir through the passages r, r<1>, Fig. 8, into the vessel b, driving the gas through the channels p, p<1>, Fig. 7, until the float s rises and closes the channel p<1>. The water in the bottle f is then drawn off by turning the valve c again into its first position. By reversing the directions of the passages p, r', the flow of water and gas from the vessel b into the reservoir a will occur simultaneously with the injection of the water from a into the bottle f, and the water will fill the vessel b while the water is being withdrawn from the bottle f. A reservoir d may be provided to contain flavouring-syrup, which is allowed to flow through passages o, o', Fig. 6, into the exit pipe h<1> when aÙrated water is being drawn from the bottle f.
