Granted: 1901-06-22
Abstract: 14,845. Yeadon, S. N., and Mason, W. D. Aug. 20. Carbon bisulphide; lime; sulphuretted hydrogen. -Gas lime or other analogous material is treated with carbonic acid, whereby sulphuretted hydrogen, carbon bisulphide, and other sulphur compounds are driven off, and calcium carbonate is formed. The latter is then removed to a furnace wherein the carbonic acid is driven off for use in the first step, and lime is left suitable for re-use in the purifiers or for other purposes. Reference is made to Specifications No. 19,183, A.D. 1889, No. 5239, A.D. 1892, and No. 104, A.D. 1895, [Abridgment Class Furnaces &c.]. The gas lime is passed by a feed-hopper 4 having regulating-rollers 5 to a cylindrical vessel 1 called a "permeator," within which is a shaft 6 fitted with blades or knives for stirring up the lime and passing it to an airtight outlet 9. The lower part of the vessel has an airtight jacket 2, into which waste gases from the furnace beneath or the carbonic acid from the retort pass, and from which they may pass to the vessel through openings. Or the carbonic acid from the interior of the retort below may be passed direct into the permeator from outside feed-pipes. The sulphuretted hydrogen and other gases given off are withdrawn by an exhauster placed at 7. The calcium carbonate falls to an airtight hopper 10, whence it is fed to a rotary retort 11, heated externally, and similar to the furnaces described in the above-mentioned Specifications. The calcium oxide is automatically discharged through a sealed outlet 12.

Granted: 1903-07-02
Abstract: 18,922. Lake, H. H., [General Electric Co.]. Aug. 28. Energy meters.-Relates to a meter of the motor type, which runs at a greater speed when the current exceeds a predetermined maximum. In the arrangement shown, an electromagnet 3 in series with the field coils of the motor, in one of the mains 8, attracts the armature 4 when the current exceeds the predetermined amount. The armature, when attracted, closes at 16 a shunt circuit containing an alarm bell 21, and at 15 a shunt circuit which increases the current in the motor armature 12, by cutting out part of the resistances 10, 13. The speed of the meter is thus increased, and an alarm bell is started, which coutinues to ring till the switch 22 is opened. Several other methods of changing the recording-speed of the meter are described, as, for example, by cutting out by an electromagnet a resistance in shunt with the armature coil, or by reducing the strength of the braking-magnets, either by shunting the field of a permanent magnet, or by reducing the strength of an electromagnet.

Granted: 1904-07-14
Abstract: 18,246. Newton, H. E., (Farbenfabriken vorm. F. Bayer & Co.]. Aug. 24. Pyrimidine derivatives; barbituric acids.-Mono- or di-alkylated cyanoacetic esters are condensed with urea by means of alkaline alcoholates, forming alkylated iminodioxypyrimidines having a formulawhich can be transformed into mono- or di-alkylbarbituric acids having a formula- In an example, the ethylic ester of the monoethyl cyanoacetic acid and urea are added to a solution of sodium in alcohol, and the mixture is heated on the water-bath for several,hours. By treating the product with dilute acetic acid 5-monoethyl-4-imino-2 : 6-dioxypyrimidine is obtained. It is soluble in water and alcohol, insoluble in ether, chloroform, and benzene, and melts at 303‹ C. Other alkylated cyanoacetic esters are similarly treated. The 5-diethyl-4-imino-2 : 6-dioxypyrimidine, prepared as described above, may be heated for about half an hour on the water-bath with sulphuric acid. The imino group is thereby split off, and diethyl barbituric acid separates in the form of needles. Other acids and other mono- or di-alkylated 4-imino-2 : 6-dioxypyrimidines give similar results. The Provisional Specification states that diethyl-4-imino-2: 6-dioxypyrimidine is heated with caustic soda lye for a short time on the water-bath, when ammonia is evolved. The product is then acidified with dilute acetic acid, producing crystals of diethyl barbituric acid.

Title: Devices for Filling Bottles and other Vessels
Inventor: SKYUM CHRISTIAN EMIL
Filed: 1903-10-06
Granted: 1903-11-12
Abstract: 21,435. Skyum, C. E. Oct. 6. Bottling.-Relates to a device connected at 12 to a siphon tube, for filling bottles &c. Liquid is sucked by the operator into a chamber 10 to establish siphon flow. When the liquid fills the chamber, the float 14 carrying a valve 15 rises and closes the valve so as to prevent liquid from entering the operator's mouth. The valve is held closed by a screw-plug 18. The flow of liquid to the tube 13, which has an adjustable nozzle adapted to enter the bottle to be filled, is controlled by a lift valve 20. The valve 20 and an air cut-off valve 23 are actuated by the same spindle, so that when the valve 20 is closed the air valve is open. The valve 20 is operated by a lever 25, the inner end of which is connected by a bail to the nipple 30 on the spindle 21. Normally, the valve 20 is closed, but on turning the lever 25 and securing it by a catch 36, the valve is opened and liquid enters the bottle. When the bottle is filled, a float 32 rises and, owing to its connection with tube 31, the tube strikes the arm 39 of the catch, and so releases the catch and allows the lever to return to its normal position, thus closing the valve. The weight 40 rolling in the tube 31, which is pivoted about the pin 28, assists in releasing the catch 36. When valve 20 closes, air enters through the valve 23 and causes the liquid in the tube 13 to run off.
