Title: Improvements in and relating to the Precipitation of Sewage.
Inventor: SPRINGBORN ERICH
Filed: 1900-02-15
Granted: 1901-01-12
Abstract: 3036. Springborn, E. Feb. 15. Filtering-media.-A mixture of powdered peat or other charcoal, sulphur, and calcium oxide, with or without a small amount of sodium chloride or sulphate, or potassium chloride or sulphate, is added to sewage for the purpose of precipitating solids, Instead of using the above-mentioned salts as separate additions to the mixture, the charcoal may be saturated with a solution of one or more of them. The sewage, thus treated, is filtered through blocks of peat charcoal. The precipitated solids may be used as manure or made into fuel, in which latter case pitch, resin, asphalt, or other hydrocarbon may be added to the mixture used for precipitating the solids.

Title: Improvements in Purifying Feed Water and the like and in Apparatus thereof.
Inventor: HARRIS ANTHONY
Filed: 1900-05-05
Granted: 1901-03-09
Abstract: 8354. Harris, A. May 5. Feedwater, purifying. - Relates to improvements o n apparatus of the kind described in Specification No. 19,621, A.D. 1899, for purifying water for boiler feed and other purposes. The water to be purified is heated in the vessel a, Fig. 1, in which it is treated, by means of steam in a jacket n closed at the top and surrounding the internal cylinder o through which the water passes. Surrounding the steam jacket is an air jacket p. Baffles r bring the water into intimate contact with the wall of the cylinder o. The reagent is admitted at c, being forced by a steam jet at s, and delivered in a tangential direc - tion to impart rotary motion to the water. The heated and purified water is preferably caused to impart its heat to the incoming impure water in a heat-interchanger of the form shown in Fig. 2, consisting of a series of thin discs w, separated by rings x, which divide the apparatus into a number of shallow compartments. Alternate compartments are put into communication in series by ports and passages in the rings, and the intermediate compartments are similarly placed in communication to form a second series by a second set of ports and passages at right-angles to the first set. The hot and cold water, respectively, are passed in opposite directions through these two series of compartments. To ensure the admixture of the reagent in the proper proportion, the water is delivered through a rotary distributer shown in Fig. 7, being thus divided into two portions, one of which (the main portion) is passed direct to the precipitating-chamber, while the other is passed through a solution apparatus containing the reagent, and then delivered into the precipitating- chamber. The water is supplied to the rotary tank 12 with elbow pipes 14 projecting from it. The reaction of the discharge through the elbows rotates the tank, and the water falls into two unequal divisions of an annular trough 18. From the larger division the pipe z, g leads to the precipitation chamber, and from the smaller the pipe 6 leads to a solution apparatus, whence the charged water is delivered to the chamber by the pipe h. The dotted lines in connection with the pipe z, g indicate a diversion through a heat-interchanger. The rotation of the tank 12 is imparted to a vane 17 for mixing the reagent with the water.

Preferably, the skin is double on the upper side as a protection against projectiles. The boat is submerged by a screw d, and is manoeuvred in a vertical plane by fins e connected in pairs and controlled from the conning-tower. It can be propelled in either direction by screws driven by an oil engine while on the surface, and by an electromotor while submerged. These motors run continuously in one direction, and are geared to one or other of the screws by clutches controlled by a lever f The screw d is driven from the main shaft by bevel gear, which can be disconnected by a lever d<5>. A rudder is fitted at each end, and is operated by a wheel in the conning-tower. Either rudder can be locked amidships by a spring bolt, which is disengaged by a line i<6>. Cutting-blades are fitted at each end of the vessel to clear away weeds &c. Hinged blades o on the bottom ring electric alarms when the vessel touches ground. Compressed air is carried in side compartments, but, when the vessel is near the surface, a supply of air is obtained through telescopic tubes k provided with valves to exclude water. These tubes may be pushed outwards by springs or screws, and are withdrawn by cords. The upper end of the inner tube is closed by a spherical valve l<2>, Fig. 9, when under water. Air may be drawn in by a pump or by an ejector nozzle. When above water, the valve is lifted by a float l connected to it by covers l<1>, The torpedoes are carried in a number of cylinders j<4>, connected together so that they can be brought one at a time in line with the ejector cylinder j. This contains a piston pushed outwards by a spring which is compressed and the piston withdrawn by a line wound upon a barrel rotated by a small oil or other engine. The discharging. device is connected to the ship by a ball-and-socket joint, and is elevated and depressed by rack-and-pinion gear. After a torpedo has been discharged, the cylinder is closed by a shutter, to exclude the water when the piston is withdrawn.

Title: Improvements in Electric Signalling Apparatus.
Inventor: WARDEN-STEVENS FREDRIC JOSEPH
Filed: 1900-06-20
Granted: 1901-06-20
Abstract: 11,208. Warden-Stevens, F. J. June 20 Signals, electric-bell; alarms, burglar &c.-Relates to the type of signalling-apparatus in which the transmitter or the receiver comprises a magnet, a soft iron body, and a coil or coils so arranged that by relative movement of the parts an alternating current is generated in the coil and may be employed for ringing bells &c. The object of the invention is to increase the rate of change of magnetic flux through the coil, and thus to render the apparatus more powerful. In one arrangement, the armature d, Fig. 1<A>, is suspended by a spring beneath the poles b of the magnet. The coil c is wound on the armature d, and a small movement of the armature causes a rapid alteration of flux through the coil, while the total magnetism remains approximately constant. The armature may be shaped so that the coil remains stationary, the armature moving through it. In another arrangement, two coils c', c<2>, Fig. 5<A>, are wound upon divided portions of the armature, so that on movement of the armature an alternative path through the coils is provided, thereby causing a large change of flux through the coils. The coils may be stationary and wound on extensions on one or both poles of the magnet. According to another method, the coil c, Fig. 6<A>, has no core, and is made long and narrow, and placed in a concentrated magnetic field ; or two or three cores arranged within and without the coil, may be employed. The apparatus may be arranged so that the magnet shall move, or that either or both magnet and armature and coil shall move. In systems where the receiver is tuned to vibrate to a certain transmitter, a number of transmitters and receivers may be arranged on one line. In order to indicate the opening of doors &c., the transmitter is supported on a door frame, and the engaging part may be hinged so that the transmitter is only operated on opening the door. The apparatus is held in the position suitable for engagement by means of gravity or a weak spring. The Provisional Specification describes a form of the invention in which the armature is of an E-shape, the central arm being elongated and situated between the magnet poles, one of the outer arms, when the armature is oscillating, coming into proximity to the pole from which the central arm is receding.

Title: Improvements in Explosion Motors.
Inventor: ALGRIN RENE
Filed: 1901-10-07
Granted: 1902-10-07
Abstract: 20,025. Algrin, R. Oct. 7. Gas and like engines.-The engine has two cylinders 1, and each of these cylinders, in which a fonr-stroke cycle is performed, is in constant communication with a smaller cylinder 5 forming the combustion chamber and containing a piston 6, which, in order to keep the compression constant with varying charges, makes strokes of adjustable length during the suction and exhaust strokes of the piston 2, but is locked during the expansion and compression strokes. There is no clearance in the cylinders at the end of the exhaust stroke, and the admission and exhaust valve cams are controlled by the lever which controls the stroke of the piston 6. Referring to Fig. 2, the connecting- rod 49 of the piston 6 is attached to a block 9 working in a slide 11, which turns about the centre o, the block being adjusted between the points o,p by a hand-lever on the shaft 47 acting through the eccentric 8. The slide 11 is locked by a bolt 58 against a stop 52 during the compression and expansion strokes, but at the beginning of the exhaust stroke the bolt is released by a cam on the valve shaft, and the parts 14, 15 of a telescopic connecting-rod, attached respectively to the crank shaft and to the slide 11, are united by a catch 16 and cause the slide 11 to turn about its centre o and the piston 6 to move to its upper position. On the suction stroke, the slide is moved back again and locked by the bolt 58, while the catch 15 is tripped by the heel 29 of the bolt lever. Valves and valve gear.-The admission valves are double-beat valves 19, 20, and are opened in opposite directions by a rod 32, which is thrust between their stems by cam gear 31, 30, 25, 24, but are closed by the cam 24 of the valves of the opposite cylinder withdrawing the rod to its midway position. The cams 24 are adjustable angularly to alter the time the admission valves are left open, and this adjustment is effected by a cam 46, Fig. 3, on the shaft 47 operating through levers 45, 44, 42 and helically-grooved sleeves on the valve shaft 21. The cams 23 of the exhaust valves 18 are adjusted by the same means, so that they may open earlier in the working stroke, when the charge is small, and thus prevent a vacuum in the cylinder.
