Title: A Process for Freeing Copper Regulus from Arsenic and Antimony.
Inventor: STONE FRED BEDDOW
Filed: 1902-07-08
Granted: 1903-05-14
Abstract: 15,222. Stone, F. B. July 8. Copper.-Regulus or similar material is freed from arsenic and antimony by mixing it with copper or iron, or any material capable of producing those metals, such as roasted regulus and carbon, and then maintaining the mixture for some hours at a temperature that will give it preferably about the consistency of stiff clay. The temperature is then raised, and molten regulus and some metal are obtained and tapped in the usual way. The metal contains the arsenic and antimony, while the regulus is free from them. The metal may be purified by oxidation in the molten state or may be reconverted into sulphide by granulating and melting with pyrites, the sulphide then being smelted for regulus in the usual manner.

Title: Manufacture of New Colour Lakes.
Inventor: IMRAY OLIVER
Filed: 1902-10-31
Granted: 1903-08-13
Abstract: 23,830. Imray, O., [Farbwerke vorm. Meister, Lucius, & Br³ning]. Oct. 31. Pigments.-Colour lakes are made by precipitating the dye-stuff obtained by the action of diazotized orthoamidobenzoic acid on the sodium salt of #-naphtholdisulphonic acid R. For example, barium sulphate is mixed with water, and a solution of the dye-stuff is added to the mixture. After warming, barium chloride is stirred in until precipitation is complete. A solution of Glauber's salt, or the solution obtained by mixing solutions of soda and aluminium sulphate, may be used instead of barium sulphate. Or, as described in Specification No. 5167, A.D. 1901, lead hydrate may be added to a solution of the dye-stuff, and then, after warming, aluminium hydrate stirred in until precipitation is complete.
Patent GB-190223915-A (GB)
Title: Improvements in Driving Gear, particularly for Motor Cars.
Inventor: LORENC VLADIMIR
Filed: 1902-11-01
Granted: 1903-09-03
Abstract: 23,915. Lorenc, V., and Lorenc, V. Nov. 1. Motor road vehicles.-Relates to self-regulating driving-gear, particularly applicable to motor cars, by which a motor of constant turning moment is enabled to exert a variable tractive force at the periphery of the wheels according to the resistance encountered. The necessary adjustment of the speed or power ratio of the gear is effected automatically without the intervention of the driver. Fig. 1 shows the simplest form of the invention. In this, the invariable oscillatory movement of the arm 2, which is operated by the engine, is transmitted to the ratchet-clutch 5, 6 through a torsional spring 3. This is capable of withstanding the distortion produced by a complete stoppage of the rotary movement while the driving movement continues. The spring may be made in several forms. Of these, Fig. 6 shows one with several parallel torsion rods, Fig. 7 shows one in which a rod 52 and split tube 53 are combined, while Fig. 3 shows a three-part torsional spring produced by milling from a solid shaft. Helical or other forms of spring may, however, be used. Fig. 8 shows the application of this mechanism for driving two car wheels directly, no balance or differential gear being necessary owing to the automatic adjustment of the speed ratio of the gearing. In this form of the invention, each road wheel is driven by two ratchets or pawlcarrying arms 4, 8 operated separately through the spring shafts 3, 11 in opposite phase to each other by the oscillatory arms 2, 10. Figs. 9 and 10 show in section a head built in the wheel hub for driving steering and driving wheels. In this, the non- rotating inner axle-box 19 is pivoted to the fixed axle-fork 17, so that the steering-axis is in the' central plane of the wheel. The wheel hub 14 with its extension 22 runs on ball bearings on the axle-box 19. In the extension 22 is frictionally held, by an adjustable strap 43, the internallytoothed ratchet ring 6. Through this the wheel is driven by the pawls carried by the rocking driving- body 23, which is oscillated by the spring shaft 3 through a Hooke's joint in the middle of the wheel hub. The pawls 5, 9 are mounted with rubber blocks 29 between them and the driving-body, which act as springs, and, in the case of staggered pawls, allow them all to come into action one after another. Two sets of pawls are provided, one for forward and one for reverse driving. Each set is provided with friction blocks 30 pressed against a smooth part of the ratchet-wheel, so that one set is always turned away clear of the teeth, and the other set is turned towards the teeth, according to the direction of driving. The pawls for one direction of driving have wedge-shaped projections 31 on one side, and those for the opposite direction of driving have similar projections 35 on the other side, so that by a lateral movement of two cups 34, 36 one set can compulsorily be put out of action, the cups being shifted by a rod 41 with a spherical eye or hook 42.
Patent GB-190227773-A (GB)
Title: Improvements in Means for Regulating the Supply of Electricity.
Inventor: CAROLAN EDGAR ALFRED
Filed: 1902-12-16
Granted: 1903-12-16
Abstract: 27,773. Carolan, E. A., [General Electric Co.]. Dec. 16. Dynamos, regulating.-Relates to the regulation of dynamos &c., and particularly of alternating- current machines. Figs. 1 and 2 show the construction of a regulator for varying resistance in accordance with the fluctuations of the current or potential. The movement of the core C within a solenoid B serves, through the agency of a counterweighted bar E<4>, to bring one or other of two connected pawls G, G<1> into engagement with a rack bar D. The pawls are carried by a slide adapted to be operated by an eccentric G<2> carried on a shaft rotated by a pulley K, and reciprocate the bar D, so operating a rheostat A or other regulating-device, such as a potential regulator. Normally, the pawls are clear of the rack, and may be held in that position by a hand-operated clip H<1>. Fig. 7 shows the application for regulating the separately-excited field of an alternator L. The solenoid B is in series with the secondary coils n, n' of two transformers N, N', the primary of the transformer N' being connected across the mains, and that of the transformer N being in series, but partly shunted by an adjustable resistance R. Diagrams showing the nature of the impressed electromotive forces and their resultant action on the regulator A under varying conditions of load are given in the Specification. In a modification, for directly regulating a feeder, the rheostat is replaced by a potential regulator. In another modification, the series transformer is omitted, the regulation being dependent upon the shunt or potential transformer.
Patent GB-190228720-A (GB)
Title: Improvements in or connected with Coin Freed Gas Meters.
Inventor: CARTER GEORGE
Filed: 1902-12-29
Granted: 1903-12-03
Abstract: 28,720. Carter, G., and Parkinson. W. C. Dec. 29. Gas meters ; actuating-mechanism.-To the side of an ordinary gas meter is attached, by a lug and screw, a valve box m, Figs. 2 and 3, which is provided with an inlet pipe n for junction with the service pipe, and with an outlet pipe o for union with the ordinary inlet of the meter. The valve, which is a cap j for the outlet port of the valve box, is carried by an arm p upon a rocking shaft q, which passes through a stuffing-box rand carries outside the valve box another arm s. This external arm being in contact with a vertical slide i on the box, which has a notch at the bottom, the valve (closed only when the slide is in its highest position) is opened and closed by downward and upward movement with a worm h, which acts alternately as a tangent screw and as a rack to a worm-wheel g in gear with the index mechanism of the meter. A turning head t with a slotted sleeve u engaging the worm is supported by the bottom y of an enclosing-cylinder i<1>, with cover d<1>, which is mounted in the top of a casing m<1> covering the valve box. This cylinder contains a broad wheel v with spokes f, which can be turned by an external crank-handle normally against a stop on the coin. Coin action.-A loop or pocket z in the broad wheel receives the coin inserted through a slightlyinclined slit a', Fig. 9, in the cylinder, and holds it up in engagement with teeth b<1> on the turning head, so that this is also turned by the crankhandle. Coin-discharging mechanism.-The coin is carried round the cylinder till it reaches a radial slit w with stop, in the bottom y, which allows it to drop out of the pocket and cylinder into a receptacle. As the angular distance between the entrance slot and the stop determines the unit of supply, the bottom of the cylinder can be turned to vary it, after removing the cover. Coin-slit closing devices.-The broad wheel acts as a shield to close the coin-entrance slot. Fraud, preventing.-The turning head is normally locked by a pawl c<1>, Fig. 9, pivoted on the cylinder cover d', but as this pawl bears a bevelled lug c<2> lying in a notch d<2> in a ring e<2> on the spokes of the broad-wheel shield, it is lifted at the commencement of the actuation, the coin pocket being slightly flared to allow the action, before the coin begins to push the turning head. Other pawls g<2> prevent reversal, but are lifted to clear the spokes by the passage of lugs h<2> on the ring under pins i<2> projecting from them. The cylinder cover d<1>, Fig. 5, and the bottom y are secured against rotation by pins p', q<1> on a vertical bar r<1>, rising from a cup, which is secured to the casing m<1> by a screw s' and receives a seal. Casing.-The casing m<1>, Fig. 2, is open in front to receive the coin receptacle l<1>, and is attached by an upper internal screw and a lower one, the receptacle being secured by a padlock in staples.

Abstract: 18,723. Boult, A. J., [Mills, M. B., and Mills, H. S.]. Aug. 31. Printing-apparatus combined with letter-boxes.- A coin-freed letter-box, chiefly intended for special-delivery mails, contains printing-apparatus, which preferably numbers the letters consecutively. The letter-box is a modification of that described in Specification No. 10,305, A.D. 1903. The printing-mechanism is carried by a pivoted frame D, Fig. 13. When the box cover A<6> is raised, a letter is inserted and received upon shoots pivoted to the plate K', the letter being held beneath the slot r by a spring device E. At the same time, the lug D<5> engages the arm D<4> and raises the printing-frame; a pawl D<6> then engages a stud d<4> to maintain the frame in the elevated position, and a stationary stud engages and rotates a ratchet-wheel D<3> which rotates the printing- wheel. To leave the printing-wheel free to rotate, the inking-device D<8>, consisting of a cylinder of semi-fluid ink having an absorbent pad at the bottom, is raised by the wheel D<3> acting upon a tooth d<11> carried by an extension of the arm D' which supports the inking-device. When the cover A<6> is lowered, a stud d<9> on the lug D<5> strikes the short arm of the pawl D<6> and trips the printing-frame, which then falls upon the letter and marks it.
