Title: The Manufacture of Substituted Amido-benzoic Acids, and of Anthranilic Acid and Colouring Matters therefrom.
Inventor: ELLIS GEORGE BELOE
Filed: 1900-10-26
Granted: 1901-10-26
Abstract: 19,202. Ellis, G. B., [Pertsch, F. A.]. Oct. 26. 5-Amido 2-acetylamidobenzoic acid is produced by heating 5-nitro 2-amidobenzoic acid with glacial acetic acid and ace ic anhydride at 125‹ C. for six hours. and reducing the 5-nitro-2 acetylamidobenzoic acid thus formed bv means of zinc and acetic acid or by other reducing-agents. Anthranilic acid is produced by diazotizing 5-amido-2-acetylamidobenzoic acid in solution in absolute alcohol by means of a current of nitrous acid at 10‹ C., expelling the excess of nitrous acid by a current of dry air, boiling the diazo solution for one hour, expelling the alcohol, and then hydrolyzing the acetylamido group by heating with hydrochloric acid. The anthranilic acid is extracted from the solution either by adding sodium acetate and extracting with ether, or by precipitating it from the acid solution by means of an excess of ammonium acetate. Dyes, artificial, are produced from 5-amido-2-. acetylamidobenzoic acid by coupling its diazo compound with a molecular proportion of a phenol or an amine, such as a naphthol or naphthylamine sulphonic acid. The dyes thus obtained are converted into others by splitting off the acetyl group, diazotizing again, and combining the diazo compound with another molecular proportion of a phenol or amine.

Title: Improvements in Driving Gear of Charging and Drawing Machines for Gas Retorts.
Inventor: WEST JOHN
Filed: 1902-10-09
Granted: 1903-08-20
Abstract: 22,002. West, J. Oct. 9. Gas retorts.-Machines for charging and drawing gas retorts are fitted with an electricallydriven motor, with driving-gear, and with friction or other clutches, which, after being first put into gear by the machine attendant, are subsequently thrown mechanically out of gear by automatic reversing and stopping gear. The mechanism shown in Fig. 1 applied to a charging-machine may be adapted to either a separate drawing-machine or to a combined charging and drawing machine, two additional clutches and an additional hand-lever being provided in the latter case to put the charger gear into action and the rake gear out of action, or vice versa. Wheels c<2>, d<3> and c'. d<4> run loose upon their respective shafts e, f, and are driven from the main shaft b of the electric motor a by the pinions c, d, d', d<2>, clutch mechanism e', f<1> allowing the shafts e, f to be revolved in either direction without stopping or reversing the direction of running of the motor a. The mechanism for travelling the machine along the retort house and for raising and lowering the coal hopper k and the charger k<2>, is driven by the shaft f, and the mechanism for sending the charger k<2> in or out of the retort is operated by the shaft e, the clutches f<1>, e<1> being operated by separate handlevers. A third hand-lever o<2> puts the clutch h<1> into gear either with the wheel h<2> of the travelling gear or with the wheel j<1> of the hoisting-gear. To drive the charger k<2> into the retort, the charger carriage and scoop k<1> are operated through the gearing, shafts, and chain drum l, l<1> ... l<8> from the shaft e, which is engaged with the wheel d<3> by the clutch e<1> when the clutch is actuated by its hand-lever. During this operation, a lever n<2>, actuated by a tappet on a wheel driven by the gearing, releases the clutch e<1> from the wheel d<3>, and puts it into gear with the wheel c<2>, thus reversing the direction of the motion and withdrawing the charger. Before the charger comes to rest, a second tappet actuates a lever n<3> and throws the clutch out of gear with the wheel c<2>. A cam-actuated lever simultaneously tightens the strap on the brake-wheel n<6> and arrests the clutch e' in its central or inoperative position, the charger thereupon coming to rest. Similarly, the clutch f<1> is moved by the second hand-lever into gear with either of the wheels c' or d<4>, to operate the travelling and hoisting gear.

Sifting grain &c.-A roller-and-ring grinding mill has special sifting apparatus, as well as settling-apparatus, for separating ground materials from air and liquids. Fig. 1 shows a vertical section of the mill, in which the ground grain or other materials, either dry, or mixed with water, or otber liquid, are expelled centrifugally by the action of the rollers r through a cylindrical sieve c, and conducted by a passage d into a conical settling-hopper e, the purified air or clarified liquid ascending into a concentric conical hopper f, and passing into the mill again by means of inclined slit-like openings a in the central column. Air may be directly introduced into the mill through a pipe g, and three concentric conical hoppers may be comprised in the settling-apparatus. The bottom b of the vat may be formed as a sieve for the production of materials of a definite granulation, the sifted materials falling on a second sieve below the apparatus or passing to a sifting-apparatus, the unsuitable material being returned to the mill at the inlet hopper l. Fig. 2 shows in section part of a mill for treating heavily-flowing moist or dry substances, in which a pair of sieves form the bottom of the vat ; one of these sieves m acting as a slide, and either closing or unclosing the slit-like openings in the fixed sieve, as a handle n is actuated.

Granted: 1903-04-23
Abstract: 28,167. Brown, H. G. Oct. 10, [date applied for under Patents Act, A.D. 1901]. Electric railways, signalling on; signalling between trans; contacts, electric.- Relates to signalling-systems for electric railways, in which a separate direct current, of lower potential than the power current, is employed for operating the signals. In order to prevent the signals from being affected by extraneous currents, such as leakage of the power current, two or more contacts controlled by polarized relays are arranged in the signal circuit, so that the circuit is broken at one or more of the contacts by extraneous currents through the relay coils. Fig. 1 shows diagrammatically the arrangement and connections of the apparatus. The rail b is divided by insulation c into sections 1, 2, 3, &c., the rail a serving as the return for the power and signal current generators d,j. The generator d is connected to the rail a, and to the feeder f, with which the trolley i on the car h makes contact. The generator j is connected to the rail a, and to the signal main m, which is connected to each section of the rail b by a lead 40, preferably including a suitable resistance 41. The coils n, o of the polarized relays are bridged across the rails a, b by connections p, q, r, s, and control the armatures 5, 19, 7, 20, the armatures 5, 7 being polarized by coils 17, 18 arranged in circuits m, 29, 24, a, which include contacts 23, 26 adapted to be made and broken by the armatures 19, 20. In the normal position, with the section 2 clear, as shown, the coils n, 17, o, 18 are energized, and the contacts 32, 33 on the arms 13, 14 of the armatures 5, 7 close the local circuit m, 36, 32, 37, 33, 15, 39, a, through the magnet 15 or other translating-device of the semaphore or signal 16. When a car h enters the section, the coils n, o are short-circuited and drop their armatures 19, 20, thus breaking the circuits of the coils 17, 18, and allowing the armatures 5, 7 to be moved by weights 45, or springs &c., to open the contacts 32, 33, on which the signal goes to ' danger.' If, when the car has entered the section, a leakage of the power current passes through the car truck to the rail b, or any other extraneous current enters the system, it may energize the coil n, owing to the drop in potential along the return rail a, and the contact 32 may be either closed or maintained open, according to the direction of the current, but no effect is produced on the coil o, which remains shunted. As the car proceeds along the section, the shunt effect on the coil o is diminished, and that on the coil n increased, until finally the conditions are reversed, or, in certain conditions, the extraneous current may pass through both coils, but in such case passes through one of them in the reverse direction, so that one or other of the contacts 32, 33 is maintained open, and no effect is produced on the signal. In a modification, the lead q is connected to the lead s, instead of to the rail b.
