Title: Improved Acetylene Gas Generator.
Inventor: BOETTCHER OTTO
Filed: 1899-04-26
Granted: 1899-07-22
Abstract: 8765. Boettcher, O. April 26. Acetylene.-Relates to apparatus for generating acetylene wherein no gasometer is employed. Within a water receptacle c is a generator b containing carbide. This generator can be raised and lowered by the screw sleeve e and hand-wheel f the sleeve being connected to the gas-outlet pipe a supporting the generator b by a nut f. The lower end of the generator is provided with a tubular housing h enclosing a double-spring valve l, having a needle-pointed upper end i, and a downwardlyextending stem d. In use, the carbide receptacle is lowered until the stem d reaches the bottom, and opens the valve sufficiently to allow water to enter through the fine opening m, to the carbide. The amount to which the valve is opened is regulated by hand, by turning the wheel f<1>, according to the quantity of gas required. If the pressure in the generator increases above that of the liquid column outside, no more water can enter until the pressure again falls. When no further gas is required, the generator is raised, the stem d leaves the bottom, and the valve l closes, preventing any further entry of water. The gas in the generator is allowed to burn out at the burners.

Title: The Preparation of New Chemical Compounds and their Use as Developing Means in Photography.
Inventor: NEWTON HENRY EDWARD
Filed: 1901-05-23
Granted: 1902-04-10
Abstract: 10,721. Newton, E. E., [Farbenfabriken vorm. F. Bayer & Co.]. May 23. Developing.-Consists in the production of new additive compounds of aromatic polyhydroxy compounds and aliphatic or cyclic nitrogen bases, which are suitable for use as photographic developers without caustic alkalies. The new compounds are produced by melting a mixture of the two components, or by causing them to react in presence of a suitable solvent. Well-characterized substances are thus obtained which are stable, possess an alkaline reaction, and are split up by alkalies into their components. Examples are given in which a compound of the formula C6H3(OH)3.NH(CH3)2 is obtained from pyrogallol and dimethylamine, and another compound is obtained from resorcin and dimethylaniline. In a similar manner, compounds are obtained from pyrogallol and mono- or tri-methylamine, piperazine, piperidine, quinoline, oxyquinoline, or triacetonamine ; from resorcin and quinoline or oxyquinoline ; from pyrocatechin and mono- or dimethylamine ; from hydroquinone and mono- or dimetbylamine, or triacetonamine ; from gallic methyl or ethyl ether and dimethylamine ; from gallic methyl ether and piperidine ; from alpha-resorcylic ethyl ether and dimethylamine ; and from gallacetophenone and dimethylamine. An example is also given in which a bath is prepared from pyrogalloldimethylamine and sodium-sulphite solution for developing images in layers containing halogen silver.

Title: Improvements in Apparatus to Control the Flow of Illuminating Gas through the Burner Tips.
Inventor: BAYLES ALFRED GRESWOLD
Filed: 1901-07-02
Granted: 1902-05-15
Abstract: 13,439. Bayles, A. G. July 2. Gas burners.-To provide a uniform flow of gas and to prevent the flow of more gas to the burner tip than can be properly consumed, a chamber or check 13 is arranged within the pillar 5 of the burner, and has the area of the inlet hole or holes 11 smaller than that of the outlet hole or holes 12. The chamber 13 is formed by two stepped thimbles 7, 8, and a gauze distributer 9 and a plate deflector 10 may be provided. As the discharge capacity of the apertures 12 is greater than the receiving-capacity of the apertures 11, the pressure of the gas within the chamber 13 is reduced, and, as the chamber formed in the pillar 5 above the check is larger than the chamber 13, the pressure will be still further reduced within this chamber, especially if the aperture in the tip 6 should have a greater capacity than the aggregate capacity of the apertures 12.

Granted: 1903-01-08
Abstract: 23,140. Thompson, W. P., [Chehet, G., and Simon, C.]. Oct. 23. Bending; forging ; stamping. -Relates to a hydraulic or other machine for making horse-shoes. The horse-shoe bar B, Fig. 8, is placed on the table 7, bevelled at 51, and across the front of the form 52. The table 7 is fixed to the slide 4 actuated by the plunger 1, Fig. 1, worked by hydraulic or other power, such as steam, electricity, &c. The bar is thus carried between the rollers 8, Figs. 1 and 2, pressed inwards by springs 9. The front of the bar is pressed against fixed pieces 14 and the sides are pressed inwards by blocks 11 actuated by wedges 10 and springs 13. The wedges are carried by the plunger 2 which also carries the block 5 for forcing the bar down against the bevelled part 51, Fig. 8. While thus held the bar is punched by drifts 20 carried by a ring 18 connected by trunnions 19 to the arms 16 of the block 6. The arms are pivoted at 17 and the block 6 is actuated by the plunger 3. The block 6 presses a projection on the bar down into the recess 50 to form the toe clip. The plungers 1, 2, 3 are operated successively by means of a lever 35 which acts successively on the valve-controlling spindles D, E, F. The water is liberated from the cylinders by similar spindles G, H, K also arranged diagonally as shown. The plungers 1, 2, 3 are returned by a constant pressure acting on the pistons 30, 31, 32. A bar of length suitable for several shoes may first be pressed to form the bosses for the toe clips, the clips, calks, and nail holes being afterwards formed by a second press which also severs the bar into lengths suitable for a shoe. These lengths are afterwards bent as above described.

Title: Improvements in the Storage and Delivery of Postage Receipt and like Stamps
Inventor: HALL JAMES LAMBERT
Filed: 1902-10-27
Granted: 1903-09-03
Abstract: 23,329. Hall, J. L. Oct. 27. Receipts, checking and recording.-Relates to a means for registering and checking the sale of postage and like stamps. The stamps are in sheets as usual with a blank strip along the front and back edges, each stamp along a transverse row being numbered similarly and the successive rows numbered consecutively. For commonly - used stamps, the sheets may have 480 rows with 100 stamps per row, while in other cases the row may consist of one, two, or any desired number. The blank strip bordering the first row is attached to a spindle or core, and, when the sheet is wound on, the other blank strip following the last row is sealed down. These cylinders may be sold as such, or separate stamps sold by using the apparatus shown in Fig. 8. Each stamp-coil a is mounted in a casing B along a line of supports d in ascending order of value, as indicated against the divisions of the drawer D which contain sealed rolls of the same value. The spring e<1> on the pivoted rod e is held against the roll by means of the spring e<2>, keeping the unwinding stamps under tension as they come through the hole f<2> between the glass plates f, f<1>. The bar g may be pressed down on the rubberheaded support g' by means of the catch g<2>, preventing the withdrawal of the stamps if desired, or the bar g may be carried by a spindle which can be pressed down upon the support g<1> by a movable projection carried in a slot on the lid when the lid is closed. A cash drawer C and the lockable storage drawer D are provided. The value of the stamps sold or remaining in can readily be obtained by noting the numbers of the stamps ready for withdrawal in each compartment, and the number of cylinders remaining in the drawer D.
