Improvements relating to the linings of vessels for metallurgical work.

Claims.—(1.) A process for lining vessels, which consists in packing against the wall thereof a plastic mass consisting of soluble glass and a basic refractory oxide of such a nature or so treated that it will not become hydrated by water, and afterwards impregnating the same with calcic chloride. (2.) The modification of the process, in which oxysulphate of iron is mixed with the basic refractory oxide before mixing the same with the soluble glass. (3.) A material for lining vessels, consisting of a mixture of basic refractory oxide of such a nature or so treated that it will not become hydrated by water, and calcic silicate either with or without oxysulphide of iron. (4.) The process of lining vessels for metallurgical purposes with a basic lining containing only a small percentage of silica, substantially as described. (5.) A vessel for metallurgical purposes having a lining containing only a small percentage of silica, and constructed substantially as described.

No. 15490.—9th October, 1902.—FRANCIS LINCOLN WHITNEY, of Fifth and Townsend Streets, San Francisco, California, United States of America, Wool-merchant. Improvements in wool- or fibre-scouring machinery.

Claims.—(1.) In a wool- or fibre-scouring machine, a vat having a perforated false bottom, an incline plane extending longitudinally from said false bottom to the top of the vat, a puddling and elevating means consisting of a series of weighted fork teeth adapted to travel through the vat up the said incline plane and discharge the fibre accumulated in front of the said teeth on to a travelling draper discharging between a set of squeezing-rolls, a distributing-roll adapted to receive the fibre from the squeezing-rolls and distribute over a submerging-drum, substantially as described. (2.) In a wool- or fibre-scouring machine, a vat having an incline plane from the bottom to the top thereof, a puddling and elevating means consisting of a series of forked teeth suspended between the radial arms fixed upon a shaft and adapted to advance through the vat and up the said incline plane, a wringing-mechanism interposed in the path of the fibre between the said incline plane and the succeeding vat, substantially as described. (3.) In a wool- or fibre-scouring machine, a vat having an incline plane from the bottom to the top thereof, a puddling and elevating mechanism consisting of a series of forked teeth suspended between radial arms upon a rotatable shaft and adapted to advance through the vat and up the said incline plane, substantially as described. (4.) In a wool- or fibre-scouring machine, a vat and a puddling and discharging mechanism consisting of a series of forked teeth suspended between radial arms fixed upon a rotatable shaft and adapted to advance through the vat, substantially as described.

No. 15491.—9th October, 1902.—GEORGE SMITH DUNCAN, of 1, Temple Court, Chancery Lane, Melbourne, Victoria, Civil Engineer (nominee of Robert Deniston Hume, of Gold Beach, Curry, Oregon, United States of America, Gentleman). Improvements in can-body-making machines.

Claims.—(1.)

In a can-body-making machine of the type specified, a hinged adjustable plate covering the horizontal rollers and made in two longitudinal sections adjustably locked together by bars, substantially as described and illustrated. (4.) In a can-body-making machine of the type specified, soldering iron or irons having a concave upper surface situated below the vertical centre of the horn, mounted on spring adjustable arms and between vertical side guides or brackets, substantially as described and illustrated. (5.) In a can-body-making machine of the type specified, an endless carrier chain or chains on one or both sides of the horn, having outward lugs projecting through a slot or slots in the horn for propelling the can-bodies forwardly, substantially as set forth and illustrated.

No. 15494.—9th October, 1902.—THADDEUS SOBIESKI CONSTANTINE LOWE, of Los Angeles, California, United States of America, Civil Engineer. Process of and apparatus for the manufacture of coke.

Extract from Specification.—The object of my invention is to improve the process of manufacturing coke, whereby a portion of the gas evolved from the coking material is utilised to keep up the heat of the ovens and of the superheating chamber, when such chamber is used, and the remainder of the gas is utilised in the form of a fixed gas by permitting steam to pass through the ovens and mixing the decomposed steam with the gas evolved from the material which is being coked. The process is intermittent, air being first admitted and mixed with the gases to heat the ovens, and the air being then cut off and steam admitted to
