Title: Improvements in Apparatus for Use in the Obtainment of Alkaline Cyanides from Crude Materials containing Cyanogen.
Inventor: CRAIG GEORGE
Filed: 1900-12-10
Granted: 1901-07-06
Abstract: 22,482. Craig, G., and Paterson, R. M. Dec. 10. Sodium salts.-Cyanides of the alkalies are obtained from materials containing cyanogen by the process described in Specification No. 11,912, A.D. 1900, with the use of a special retort furnace, charge cooler, lixiviators, concentrator, and crystallizing-vessel. In the lixiviators, the cyanides are dissolved out from the furnace product with liquid ammonia, which is afterwards evaporated from the solution. Each lixiviator is a vessel w<1>, which may be closed by a cover, and has a pipe connection at the bottom to admit ammonia from a holder, or weak solution from another lixiviator, one d' at the top for discharging the solution to another lixiviator or by a pipe g to the concentrator n, another l<1> at the top connecting the vessel by an exhaust pipe i with an ammonia pump p, for removing ammonia from the residue, and two other pipes for passing air through the vessel and conveying residual ammonia to an absorber. The vessel w<1> has two internal shoulders supporting perforated plates and filtering-cloths, the lower plates being held down by a bolt y<5>, and the upper ones by a spring z<2>. A false bottom with a lifting- rod y<3> is provided for removing the residue. Connecting-pipes and valves permit the lixiviators to be worked in series, in any order. The concentrator consists of a vessel n from which ammonia is exhausted to the pipe i, the solution passing to a crystallizing-vessel o. The concentrator is surrounded by a jacket and warmed by a coil of pipe s<2>, into which ammonia is compressed by the pump p; the ammonia from the coil s<2> passes to the holder. The crystallizer o is warmed by a water jacket, and has a removable cover and a receptacle for the cyanide. The cyanide is freed from ammonia by exhaustion to the pipe i, and afterwards drawing air through it to the ammonia absorber, for which pipes o', o<3> are provided.

Title: The Manufacture of Dyestuffs of the Acridine Group.
Inventor: RANSFORD ROBERT BOLTON
Filed: 1901-09-30
Granted: 1902-08-07
Abstract: 19,486. Ransford, R. B., [Cassella & Co., L.]. Sept.30. Dyes, artificial.-Acridines containing primary or secondary amido groups, or their leuco compounds, are converted, by beating them with formaldehyde under pressure, into new yellow to orange dyes of the acridine group which are distinguished by their intensity and fastness to light. Acridine yellow and its substitution products yield the best results. An example is given in which tetraamidoditolylmethane is heated in an autoclave with hydrochloric acid, and, when the acridine ring has been formed, the vessel is allowed to cool, formaldehyde is added, and the vessel is closed and further heated to 125‹ C. for six hours. After cooling to about 80‹ C., the mixture is poured into salt water, whereby the new dye is precipitated. During subsequent filtering and drying, any leuco compound present is oxidized.

Title: Improvements in or relating to Disinfecting Apparatus.
Inventor: BOULT ALFRED JULIUS
Filed: 1902-01-04
Granted: 1902-06-25
Abstract: 277. Boult, A. J., [Fournier, E.]. Jan. 4. Disinfecting. -Apparatus for instantaneously vaporizing disinfectants, especially formacetone, is inclosed in a casing 4, and is provided with a heating-burner 6. Disinfectants which are not easily decomposable are supplied through the coil 10, and, when vaporized, pass by the pipe 39 to the chambers in which goods to be disinfected are placed. Decomposable disinfectant is forced through the pipe 21 into a worm enclosed in the boiler 11, and, after vaporization, enters the chamber through the pipe 22. The boiler is fitted with heating-tubes 18, 19, a safety-valve, &c., and with a pipe 26 by which steam can be supplied to the chamber. The pipe 26 is connected to the pipe 22 by a branch 27, so that steam can be forced through the worm to clean itout. Cocks 28, 29 serve to gauge the level of the liquid, and the latter may also be used to return condensed or partly-condensed vapour into the boiler. The worm is made easily removable, and is. provided with supports to allow it to stand by itself. Fig. 2 shows a modified arrangement, in which the coil 10 alone is used for vaporizing the disinfectant, and the burner 6 is enclosed in a double casing 31, 32, 33, so as to cause a current of fresh air, as well as the heated air, to enter the chamber to be disinfected. Either part of the apparatus shown in Fig. 1 can be used independently.

Filed: 1902-04-11
Granted: 1903-03-26
Abstract: 8422. Sharp, J. April 11. Gas meters ; coin action ; coin-slit closing-devices. -The delivery valve 20 of a prepayment gas meter is connected by universal joints to arms 21 carried by a spindle 17 carrying a crank 16 with a pin 15 engaging a slotted crank 14 on a spindle 1. A spur-wheel 4, operated by the meter indicating mechanism, and a spur-wheel 2, operated through the gearing shown by a coin-actuated wheel 37, are mounted loosely on the spindle 1 and have crownwheel teeth 3, 5 engaging an intermediate spurwheel 6 mounted loosely on a stud 7. This stud passes through a sleeve 8, is secured to the spindle 1, and carries a stop-arm 9, which strikes a spindle 25 when the maximum number of coins has been inserted. A pointer 10 on the spindle 1 indicates on a dial 11 the amount of unused gas paid for. The valve seat has a central rib 23. The slotted coin receiver 26 has a wing or cam surface 27 and end spindles 28 with a squared end 30 to receive the operating-handle. When a coin is inserted, it depresses the lower end of a weighted lever 34, so as to cause the other arm to block the coin slit. The coin passes a weighted pawl 35, which prevents its return, and comes into engagement with one of a number of arms 36 on the wheel 37. The intermediate wheel 40 may be a change-wheel. In a modification, the valve 20 is mounted on the end of the spindle 1, which is moved longitudinally by the pin 7 or pins on supporting-arms engaging spiral grooves, the pins on the supporting-arms or the pin 7 engaging guide-slots. In this case the wheels 2, 4, 6 are bevel-wheels, and the wheels 2, 4 are operated by worms. According to the Provisional Specification, the sleeve 8 may have a coarse screw-threaded surface to engage a similar-shaped groove on the spindle. The coin inserted may press a spring-released pawl into engagement with a ratchet-wheel, and a roller may be fitted on a cam portion of the coin receiver to lessen friction.
