Granted: 1899-04-22
Abstract: 13,283. Wheeler, J. June 14. Resins and resinous compounds.-Betulin derivatives, which are termed "pyrobetulin" and " pyrobetulin anhydride," are produced as follows : -The finely - ground epidermis of birch bark, preferably that of white birch (betula alba), is mixed with an oxygen carrier, such as potassium nitrate, and the mixture is compressed into the form of tablets, which are ignited for the purpose of subliming the betulin. When pyrobetulin itself is required, 4 to 8 per cent. of nitrate is used, and the burning is performed rapidly in an ample air space ; when pyrobetulin anhydride is to be produced, the percentage of nitrate employed is from 1 to 4, and the tablets are packed closely and burnt more slowly. The apparatus consists of a chamber adapted to rest upon a suitable floor, such as slate, and provided with an opening in the top for receiving a hood 4, which is fitted with a rubber ring 5 for making a tight joint. Within this hood is supported on cross-bars a stand 8 for carrying the lamp 9, which is supplied with a regulated quantity of air by holes 9<a> and a perforated movable ring 9<b>. The tablets are placed vertically in radial slots 17 in a plate 13, and their lower edges rest upon a ring 17<a>. A wire-gauze chimney 23 is supported in a collar 24. In operation, the tablets are ignited at their upper edges by a jet of gas, any flame produced is then extinguished, and the fumes thereafter produced are deflected downwards by the hood and are deposited upon the floor of the chamber.

Granted: 1900-05-26
Abstract: 11,485. Hoghton, H. P. June 2. Barometers.-Relates to aneroid barometers, the object being to prevent friction in the moving parts. The lever d, d<1> is connected to the vacuum chamber g by a spring f which receives the stress. The lever, instead of being pivoted, is supported by fine flat springs a, c, preferably held in tension by a spring e, the planes of the springs passing through the imaginary axis of the lever. This method of support may be varied. Thus, in the form shown in Fig. 6. springs p, p are wound in opposite directions, partly round a cylinder 0 on the lever d and partly round a fixed cylinder q; or a spring or springs r, Fig. 7, may support the lever, the stress being transmitted through the spring s. Several vacuum chambers may be employed, acting on corresponding levers d. The extremity of the lever d is attached to a helical spring h, or its equivalent, wound partly right and partly left handed. At the junction of the two helices the index-finger is attached, and, where more than one revolution of the finger may take place, a second finger may be attached near the end of one of the coils, to register the number of complete rotations of the other. Each finger works over a dial, and, where the displacement of the finger along the axis of the coil is considerable, the lever d is so connected to the dial (which works on guides) as to move it with the finger.

Title: Improvements in and relating to Furnaces for the Prevention of Smoke and the Economization of Fuel.
Inventor: BROOKES ALFRED GEORGE
Filed: 1899-06-15
Granted: 1900-01-27
Abstract: 12,489. Brookes, A. G., [Ott, E.]. June 15. Steam - generator &c. furnaces; smokeconsuming.-A portion of the products of combustion, mixed with fresh air, is returned to the a s h p i t together with steam or water vapour which is supplied for the purpose of generating water gas in the furnace. Communication is established by means of a hollow fire bridge between the ashpit and the throat of the furnace. Figs. 1 and 2 show the improvements applied to a water-tube boiler. The fan g, when in operation, draws some of the gases from the flue f through the passage i, and also draws air to mix with them through passages k, Fig. 2, delivering the mixture into the ashpit, where it mingles with steam or water spray delivered through the perforated pipe r. The bulk of the mixture passes up through the grate into the fire, but a portion passes through passages n and l in the bridge, and is discharged through forwardly-directed openings to meet the products of combustion. Dampers p and q regulate the flow of the gases from the flue f to the chimney flue d and the passage i respectively. Figs. 4 and 6 show the application of the invention to an internally-flued boiler. The furnace gases, after passing through the furnace flues and forward along the side flues, descend to the flue f, whence a portion of them is withdrawn, together with air admitted at k, by the fan g, and supplied through the casing s to the ashpits. The firebridge has passages as in the former arrangement. Instead of supplying steam or water to the ashpit, it may be delivered into the products of combustion, or into the fresh air, or both, before they are mixed together ; or, according to the Provisional Specification, it may be dispensed with altogether. The products of combustion may be drawn from any suitable point in the flues or chimney.

Title: Improvements in Machines for Forming Caps for Closing Bottles, Jars and other Vessels.
Inventor: DYMOND GEORGE CECIL
Filed: 1900-08-07
Granted: 1900-12-15
Abstract: 14,151. Dymond, G. C., [American Stopper Co.]. Aug. 7. Stoppers. - Relates to machines for forming caps for bottles, jars, &c. The caps are fed singly from the chute 18 into the carrier 22 by the sliding plate 19, which is reciprocated by the eccentric 20 on the cam shaft 16, and serves also to align the cap in the carrier. The carrier is then advanced towards the rotating die by the lever 23, actuated by the cam 43. The lever 23 is connected to a sleeve 24 loose on the end of the carrier plunger 26. During the first part of the movement of the lever, the sleeve compresses the spring 31, and during the latter part of the movement the sleeveengages a shoulder on the plunger, and advances the plunger so as to force the cap on to the die 11. The plunger 26, Fig. 12, has a revoluble head 28, which is rotated by contact with the cap, antifriction balls 29 being interposed between the head and plunger. The cap is formed between the dies 11, 14. The die 11 makes three revolutions to each revolution of the die 14, and has die surfaces on its whole circumference, the die 14 having die surfaces on a third of its circumference. For the remaining two-thirds of its circumference, the die 14 is disengaged from the die 11, to permit the removal of a finished cap and the supply of a fresh cap to the die. The dies shown are adapted to form the cap flange with a series of longitudinal ribs and intervening plain faces, in the latter of which internallyprojecting lugs are formed, but the invention is independent of the dies. The die 11 is furnished with die sections 34, mounted on springs 38, and adapted to be forced outwards by the disc or spreader 37, so as to act in conjunction with the die faces 36 on the die 14, Fig. 9. The spreader 37 is actuated by the lever 39 from the cam 41, and serves also to expel the finished cap from the dies. The spring finger 47, Fig. 4, prevents the finished cap from being returned to the carrier.
