Title: Improvements in Atomizers for Spraying Liquids applicable also for Fire-extinction.
Inventor: JENSEN CHRISTIAN ALBERT
Filed: 1898-07-19
Granted: 1899-07-19
Abstract: 15,795. Jensen, C. A., [Sch³tz, C., and Ffund, A.]. July 19. Spray-producers.-Relates to an apparatus for moistening air, which can be used also for fireextinguishing purposes. A spray is produced by jets a<1> issuing from a ring of holes in a nozzle a on a pipe h. The size of the jets is regulated by rotating the outer shell of the nozzle by means of an arm i and a screw k rotated by a chain k<1>. The jets impinge against a casing b, and break up into a spray. A second casing b<1> surrounds the casing b. Holes d are formed in each casing. The two casings can be rotated independently. When used for moistening air, the holes d are set non-coincident, and out of the line of the jets a<1>, but by setting the holes in line with the jets and opening the nozzles full the apparatus becomes suitable for fire-extinction. It may also be set in this way when cleaning, a cover e being lowered also as shown in dotted lines, by turning it round on its screw support. A funnel l collects and discharges the waste water. In a modification, the jets impinge on curved plates carried by springs.

Title: Manufacture of Cellulose Esters.
Inventor: WEBER CARL OTTO
Filed: 1898-10-19
Granted: 1899-07-01
Abstract: 22,029. Weber, C. O., Cross, C. F., and Frankenburg, I. Oct. 19. Cellulose esters.-Cellulose esters of the higher fatty acids, or of aromatically-substituted fatty acids, or mixed esters of fatty or aromaticallysubstituted fatty acids, are produced in the form of light fine flakes soluble in solvents for cellulose acetate, by the following process :-The zinc or magnesium salt of the acid to be employed, preferably as a concentrated solution, is mixed with a molecular proportion of structureless cellulose, such as that obtained from cellulose sulphocarbonate, and the mixture is dried on a water bath. The product is mixed with two molecular proportions of an acid chloride and a small quantity of an acid anhydride, each of these being a derivative of any one of the above-mentioned acids, and the mixture is heated on a water-bath until it thickens. Nitrobenzene is then added, first in small doses, and later in increasingly large doses, the quantity being sufficient to prevent the temperature from rising above 70‹ C. The nitrobenzene moderates the reaction and prevents the aggregation of the product into a solid mass. It may be replaced by its homologues, or by epichlorhydrin or dichlorhydrin. The reaction mixture consists of a solution from which the cellulose ester is precipitated in fine light flakes by pouring the solution into alcohol.

Title: Improvements in Electrical Apparatus for Sorting Articles according to one of their Dimensions.
Inventor: LOCK WILLIAM HENRY
Filed: 1899-08-10
Granted: 1900-08-10
Abstract: 16,267. Lock, W. H., and Milner, J. J. Aug. 10. Linotype machines.- The apparatus is for sorting articles according to their thickness, and as shown is for separating the matrix blanks of the linotype machine described in Specification No. 14,582, A.D. 1890, into three sizes, too small, standard, and too large. B y increasing the number of " feelers " in the gauge and of shoots in the apparatus it may be adapted for a greater number of sizes. The blanks to be gauged are piled up in a hopper, and are fed therefrom, one at a time, by a pusher reciprocated by the action of a cam fixed on the spindle of the driving-pulley of the machine. The mouth of the hopper is fitted with an adjustable spring plate, to prevent more than one blank from being delivered at a time ; this plate yields slightly to an abnormallythick blank, to prevent jamming. The blank so fed forward is left at 100 under a verticallyreciprocating gauge 34, which is raised and lowered also by cam action. The gauge has two " feelers " 45, 46, consisting of spring pushers, delicately adjustable, and connected, as shown, with a battery 97 and electromagnets 103, 106, which control the switches or gates 69, 68 of the sorting-shoots. If the blank 100 is too small, the lower pusher 45 does not touch it, and the next on-coming blank pushes it forward, and discharges it down a central shoot between the switches or gates 68 and 69, which are held parallel to each other by springs 109 and armatures 107. If the blank be of normal size, the pusher 45 touches it, circuit is completed for the electromagnet 103, and the gate 69 is swung to the left, closing the central shoot and guiding the blank down one on the right ; the gate is locked in this position by a spring catch. Should the blank be too large, the pusher 45 is thrust upward and touches the pusher 46, and both electromagnets 103, 106 are energized. The gate 68 is thus swung to the right and locked, and the blank passes down a shoot to the left. In the continued action of the machine, a reciprocating bar frees the latches, so that the gates are returned to normal position, and a pusher mechanism turns the sorted blanks on end, and pushes them into receptacles with sliding bottoms. The downward movement of the gauge is exactly determined by finely-adjustable screw stops.

Abstract: 22,334. Demoulin, G. M. Nov. 8. Balancing moving parts; cylinders, arrangement or disposition of; compound and multiple. expansion engines; engines with two pistons reciprocating oppositely within same cylinder.-Relates to steam, gas, and like engines, and comprises several arrangements of simple and compound engines designed with a view to attaining partial or entire balance. Several forms of engines with two or three cylinders working on oppositely-disposed cranks are described. Fig. 3 shows one of these. The cylinders are so disposed that their axes come as closely together as possible. The upper cylinder 1 is a high-pressure cylinder, and the two lower ones 2, 3 single-acting lowpressure cylinders, the steam expanding on the down-stroke in their upper ends. Distribution to the three cylinders is effected by a suitable single valve. A two-cylinder compound engine, a doubleacting three-cylinder engine, and a triple-expansion engine are also shown. Fig. 4 shows a threecrank compound engine with two pistons reciprocating in opposite directions in a single cylinder. Steam first acts in the upper end of the cylinder at a, and then expands in the space between the two pistons P, P<1>. Fig. 9 shows an engine with two cylinders disposed on opposite sides of a two-throw crank shaft. The pistons in this are weighted at p, p<1> so as to bring the centre of gravity of the two reciprocating masses as nearly as possible into the median line of the engine. In connection with engines of the above kinds, two-throw crank shafts with the central web bent are shown, which enable the cylinders to be placed very closely together. Fig. 2 shows a crank shaft in which the same result is obtained by making the central web in the form of a solid disc g with countersunk borings a on opposite sides.

Granted: 1901-04-13
Abstract: 3582. Rossi, A. J., MacNaughton, J., and Edmonds, W. D. Feb. 19. Aluminium, calcium, and magnesium titanates.- To obtain from titaniferous ores or slags a concentrate containing high percentages of titanic oxide, and suitable for use in the production of ferrotitanium, the ores or slags are mixed with sufficient carbon, (which should be as pure as possible), to reduce all the silica and iron oxides present, but not the titanium oxide, and with a base, such as powdered lime or, less preferably, magnesia or alumina, using a quantity of base sufficient to form a titanate with all the titanium present. The mixture is then heated to a temperature sufficiently high to reduce the iron oxide and silica, but not high enough to reduce the titanic oxide. The quantities of carbon and lime to be added, and the temperature to which the mixture is to be raised, must be made the subject of a test for each case. In one example, the mixture was composed of 100 lbs. of ore, 20 lbs. of carbon, and 12À6 lbs. of lime, and the temperature employed is about 1700‹ C. The temperature may be obtained electrically, employing, for example, a current of 600 ampÞres and 40 volts. From the above charge, 58 libs. of pig iron and 30 lbs. of calcium titanate were obtained. The titanate floats on the molten metal, and is run off. The iron contains all the silica, phosphorus, manganese, &c., the products being really a ferro-silicon. The titanate is then used for the production of a ferro-titanium alloy by a known process.
