of superimposed carbide baskets or trays being slipped loosely over a central rod or tube, or firmly fixed to said tube in the form of shelves and fitted in a receiver in such a manner that the carbide baskets, trays, or shelves together with the rod can all be lifted out together, whilst, when the trays, baskets, or shelves are arranged rigidly on the central rod or tube the walls of the receiver may be provided with doors. (4.) A form of construction of the generator described in claim 1 characterized by the water-inlet passage being arranged as a perforated tube surrounded by a tube having a longitudinal slit for delivering the water to the carbide, in which slit a sliding scraper is arranged in such a way that the slot can be scraped free. (5.) In the system described in claim 1, the arrangement to avoid an excess of gas being evolved in the generator characterized by the single admission-hole for the water being arranged at the bottom of the generator and covered by a flap-valve which can be lifted by the water, unless the pressure of gas in the trays, baskets, or shelves reaches an excess, in which case such excess pressure will keep the valve closed against the inflow of water. (6.) A modification of the valve described in claim 5, in which the single admission-hole for the water in the bottom of the generator may be closed by the generator being pressed with its bottom upon an indiarubber or other pad provided in the bottom of the water-chamber, either by means of a bayonet-joint or thumb-screw. (7.) In the system described in claim 1, the arrangement of a spirally curved tube as an internal prolongation of the air-inlet in such a way as to prevent explosion through accumulation of gas in the upper part of the water-chamber, which on leaking through the air-inlet might be accidentally ignited, in which case it can only burn as a quiet flame. (8.) In the system described in claim 1, the arrangement of several of the gas-generators in a circle around a single gasometer-bell, which generators, for the purpose of keeping them cool, may be arranged in an annular tank having a circulation of water, or be provided with fins having a large radiating surface, the said generators being all connected to a common water-supply pipe and a common gas-exit pipe in such a way that one or more or all of the generators may be set into action as required to keep the gasometer-bell charged according to the consumption. (9.) In the system described in claims 1 and 8, the arrangement of a blow-off device for allowing the escape of any excess evolution of gas which might cause the gasometer-bell to rise too high, characterized by a blow-off pipe having its upper end closed by a movable cap in the gasometer-bell, which blow-off pipe is surrounded by a sleeve depending from the top of the bell, which sleeve has a constriction or inward projection at its lower end to engage and lift the cap off the blow-off pipe when the bell exceeds the desired extent of rise. (10.) In a system of acetylene-gas generation, an apparatus for purifying the gas characterized by an arrangement of gauze immersed in the liquid in a tank having an inlet and an exit for the gas in such a way that the gas is forced to pass through the liquid and the gauze, and is thus thoroughly purified of mechanical impurities. (11.) A form of construction of the gas-purifier described in claim 10, in which two layers of gauze are employed, one a little above the other, and in which the mechanically purified gas is also passed through a chemical scrubber before being taken for consumption.

No. 11533.—15th April, 1899.—CHARLES FELTON SCOTT, of 6214, Sellers Street, Pittsburg, Pennsylvania, United States of America, Electrical Engineer. Improvements in systems of electrical distribution.*

Claims.—(1.) Converting a multiple-wire single-phase alternating-current system feeding translating devices in multiple series into a four-wire two-phase system by connecting the neutral or middle conductor and a fourth wire respectively to the terminals of a circuit carrying currents in quadrature with those in the multiple-wire system. (2.) The modification of the invention in which the middle or neutral conductor of the multiple-wire system and the fourth conductor are respectively connected to the terminals of the secondary coil of a transformer, the current in the primary coil of which is in quadrature with the current in the outer or main conductors of the multiple-wire system. (3.) Systems of electrical distribution, arranged substantially as described.

No. 11559.—26th April, 1899.—KUGELLICHT GESELLSCHAFT MIT BESCHRÄNKTER HAFTUNG, of 82, Loebtauerstrasse, Dresden, Germany (assignees of Ernst Salzenberg, of 1, Marianen Strasse, Orefeld, Germany, Manager of Gas- and Water-works). Improvements in or relating to the production of incandescent gaslight.

Claim.—Process for the production of an incandescent gaslight, characterized by the arrangement of a fine-meshed resisting-mantle, fed by gas under pressure of one or more atmospheres, which gas expands the mantle like a balloon, the result of this arrangement being a yellow incandescent gaslight of high illuminating-power and even radiation in all directions.

No. 11706.—12th June, 1899.—ISAAC SMITH, of the firm of Sydney Smith and Sons, of Basford Brassworks, Nottingham, England, Brassfounders. An improved apparatus for use as a liquid-meter, rotary motor, pump, and for similar purposes.

Claims.—(1.) The combination of a drum provided with two or more spiral or similarly curved channels, and an outlet to each channel, and an inlet-port box provided with inlet-ports and a directing-cone, constructed, arranged, and operating substantially as described with reference to the drawings, and for the purposes set forth. (2.) The combination of a drum provided with two or more spiral or similarly curved channels whose sectional area decreases from the centre outwards, outlet-ports in the said drum to each channel therein, a port-box with inlet-ports differing in number to the number of channels in the drum, and a cone for directing the inflowing liquid, constructed, arranged, and operating substantially as described with reference to the drawings, and for the purposes set forth.
