Title: Improvements relating to Rotary Motors
Inventor: BECHT ALBERT LOUIS
Filed: 1901-05-28
Granted: 1902-04-24
Abstract: 10,957. Becht, A. L. May 28. Annular-chamber type.-In the form shown in Figs. 1 and 2, the drum B and abutment D are connected by internal toothed gearing d, and have two piston heads c and one recess f, respectively. The abutment shaft E is geared to rotary expan- sion valves H governing admission ports j, which are used for forward and reversed running, respec- tively. The drum and abutment have lateral rims s, t entering recesses in the casing A to prevent leakage. The piston heads have L-shaped grooves v, so that the motive fluid has a packing action on the casing wall. The engine may be used with steam or explosive gases, and may be modified by altering the size of the drum gearing, or by putting it outside the casing. A non-reversing engine has two diametrically-arranged distributing-valves.

Granted: 1902-10-02
Abstract: 22,248. Barker, W. B. Nov. 5. Signals, marine and ship.-Relates to apparatus for signalling the direc- tion in which a ship is sailing, by means of code blasts of long and short sounds on the fog-horn, steam whistle, &c. The code is ar- ranged preferably for the principal eight points of the compass, and sym- bols corresponding with the code signals are arranged on the handles w of the hand-wheel b, by means of which the appa- ratus is set to give the required signal. The hand-wheel is connected to the hollow cylinder a, which is furnished with eight vertical rows of cam pro- jections for actu- ating the lever c connected to the steam whistles &c., each row corre- sponding with one of the code signals. The hand- wheel is rotated to bring the proper row of pro- jections into position, and the cylinder is then raised by the cord f actuated by the foot pedal e, or by a hand-lever &c., so that the projections operate the lever c. The upward movement of the cylinder is controlled by the dash-pot piston k, which is connected to the band-wheel b by a rect- angular pin r, and is provided with lugs p to receive the guide-rods o of the cylinder. The weight of the piston is carried by rollers s. The hand-wheel b is provided with angular teeth or projections v adapted to engage with correspond- ing teeth on the pedestal d, to hold the hand-wheel in the position to which it is set. The signal symbols on each of the handles w are enclosed in a representation of a ship, the bow of which is directed radially outwards, and the signal given corresponds with that in the representation which points to the bow of the ship.

Title: Process for the Manufacture of C C-dialkyl-barbituric Acids.
Inventor: BOEHM FREDERICK
Filed: 1903-01-23
Granted: 1903-06-18
Abstract: 1664. Boehm, F., [Fischer, E.]. Jan. 23. Medicinal preparations - a-Dialkylbarbituric acids, which contain alkyl radicles rich in carbon and possess powerful hypnotic properties, are produced by acting upon dialklymaloinic esters and urea or alkylureas with metallic alcoholates. The reaction is represented by the following equation :- An example is given in which diethylbarbituric acid is produced by heating 3 atomic proportions of sodium in absolute alcohol with one molecular proportion of diethylmalonic ethyl ester and rather more than a molecular proportion of urea With a smaller proportion of sodium the yield is less. Sodium methylate may be used instead of sodium ethylate, and oxides of barium and calcium with absolute alcohol. In other examples, dipropyldimethyl-, methylethyl-, methylpropyl-, ethylpropyl-, di-isobutyl-, di-isoamyl-, and dibenzyl-barbituric acids are produced from the corresponding dialkylmalonic esters and urea, and diethyl-N- methyl- and diethyl-N-phenyl-barbituric acids are produced from diethylmalonic ethyl ester and methyl and phenylurea respectively.

Granted: 1904-06-16
Abstract: 16,990. Casson, T. Aug. 4. Organs.-An arrangement of a set of chambers and valves is adopted to enable the highest, or lowest, note only of a harmony struck on the keyboard to sound, as in the construction of this kind described in Specification No. 6496, A.D. 1894. The contiguous cells h<1>, h<2>, h<3> are provided with self-acting check valves o', o<2>, o<3>. Assuming the pallet n<2> to be opened by the key action, wind from the chest m passes to the cell h<2>, the pallet j<2> closes, and the valve b opens, causing the motor c<2> to collapse, and the pallet d<2> to open and sound the note. The wind in the cell h<2> passes by a tortuous course and directly by the check valves to all the cells and chambers of the lower notes to prevent them being sounded. The pneumatic lever for the valves or pallets is constructed to rise at both ends, but to a greater extent at one end than at the other, and may present a greater area to wind pressure at one end than the other.

Abstract: 17,333. Reifgraber, J. J. Aug. 10. Machine guns.-In order to open the breech automatically, the breech-bolt 22, Fig. 6, is connected with an annular piston 24, so that the explosion gases, issuing through lateral openings, Fig. 1<a>, communicating through passages 16, with the bore, impinges against wings 25, Fig. 6, on the piston 24 and rotates the breech-bolt into the unlocked position, after which the pressure of the gases forces the breech-bolt rearwards. The breech-bolt, provided with an interrupted locking screw-thread 61, Fig. 1<a>, is closed by teeth 64 and an arm 65 on a handle-operated cam engaging respectively the interrupted screw 61 and a recess 66 in the breechbolt, and is turned into the locking position by worm-teeth 67 on the cam engaging corresponding teeth 68 on the breech-bolt. The cartridges are fed downwardly into the gun by gravity through escapement mechanism, and the empty shells are discharged downwards and forwards. The firing- pin is shaped as shown in Fig. 4, and the shoulder 40 at its rear end, with which the sear engages, is provided with a notch 41, which allows the firing- pin to disengage from the sear when the breechbolt is locked, providing the trigger is pulled. The sear 44 Fig. 1<a>, and the trigger 43 are mounted on the same axis, and the back of the trigger 43 hears against a lateral projection on the sear.

Advertis ing.- Consists of an endless band advert i s i n g -apparatus for railway carriages, steamers, tramcars, omnibuses, and other conveyances, which is actuated by the rocking and jolting movements of the vehicle. When a pendulum d, pivoted at e and fixed to a doublearmed lever f, g, rocks, one arm f is raised, and a lever k drives a ratchetwheel o by means of a pawl p, thus actuating the band carried by the rollers A, B. When the pendulum swings back, the other arm g is raised, and so each end of the top roller A is actuated alternately. When the vehicle jolts, the pendulum is depressed against the resilience of its spring suspension x, and the restoring action of the spring raises the lever f, g horizontally, so that the levers k, l actuate both ends of the top roller simultaneously. A frame w and a bar v guide the up-and-down motion of the pendulum, while stops on a bar q limit its swing. The roller B is carried in a spring bearing, so that by removing cross-bars q, s and raising the roller, the endless band may be slipped off the rollers and replaced by another. A button z allows of the rollers being operated by hand when the vehicle is not in motion. Instruments such as barometers, thermometers, &c. may be attached to the casing if desired.
