No. 18100.—24th October, 1903.—CHESTER CHARLES SMALL, of Newton Highlands, Massachusetts, United States of America, Inventor. Improvements in or relating to top lifts for boots and shoes.*

[This is an application, under section 106 of the Act, the date given being the official date of the application in the United States of America.]

Claims.—(1.) As a new article of manufacture, a top lift comprising a blank cut from a piece of leather, and thereafter compressed and condensed by great pressure, both upon its faces and its edges, to such an extent that substantial changes are effected in its characteristics or qualities, substantially as described. (2.) As a new article of manufacture, a top lift cut from soft or spongy leather, and thereafter compressed and condensed by great pressure, both upon its faces and its edges, to such an extent that substantial changes are effected in its characteristics or qualities, substantially as described. (3.) As a new article of manufacture, a top lift comprising a piece of leather compressed and condensed, and having its tread-face and its edges hardened by great pressure exerted positively and directly upon the top lift to such an extent that substantial changes are effected in its characteristics or qualities, substantially as described. (4.) As a new article of manufacture, a top lift comprising a blank cut from a piece of leather, and thereafter compressed and condensed by great pressure, both upon its faces and its edges, to such an extent that substantial changes are effected in its characteristics or qualities, substantially as described, and having a design impressed in one of its faces by such pressure. (5.) As a new article of manufacture, a top lift comprising a blank cut from a piece of leather, and thereafter compressed and condensed by great pressure, both upon its faces and its edges, to such an extent that substantial changes are effected in its characteristics or qualities, substantially as described, and having its flesh side corrugated or roughened by such pressure. (6.) As a new article of manufacture, a top lift comprising a blank cut from a piece of leather, and thereafter compressed and condensed by great pressure, both upon its faces and its edges, to such an extent that substantial changes are effected in its characteristics or qualities, substantially as described, and having its diameter reduced by such pressure. (7.) As a new article of manufacture, a top lift comprising a blank cut from a piece of leather, and thereafter compress

and condensed in all its dimensions to a uniform thickness to such an extent that substantial changes are effected in its characteristics or qualities, substantially as described. (8.) As a new article of manufacture, a top lift of leather the characteristics and qualities of which have been substantially changed by the compression and condensation of said lift throughout and in all of its dimensions, substantially as described. (9.) A top lift for the heels of boots and shoes manufactured substantially as described.

No. 18233.—28th July, 1904.—THOMAS MACALPINE, of 22, Sutton Court Road, Chiswick, London, England, Doctor of Science, Consulting and Research Chemist, and Chemical Engineer. Improvements in means and apparatus for refining oils.*

Extract from Specification.—According to this invention, firstly, the crude oil is subjected to the action of a saline solution which separates the acids in the oil from the oil, and enables the other impurities to be capable of being easily and cheaply oxidized, which oxidation destroys the affinity of the impurities for the oil. Secondly, the impurities, after being treated as described and partially oxidized during the saline treatment, are further oxidized during distillation by mixing into the oil before distillation a compound that will mix into the oil and give off oxygen by the heat of the distillation, such as a preparation of manganese, which further oxidizes the impurities; and during this part of the process—that is, during distillation—it is advantageous to introduce into the oil, while in the still, steam of a lower temperature than 212° Fahr.—preferably about 170° Fahr.: the effect of such low-temperature steam in combination with the oxygen from the manganese finishes the complete separation of the impurities from the oil, so that they (the impurities) do not pass over with the distillate, but remain in the still with the residuum of the distillation.
[Note.—The above extract from the specification is inserted in place of the claims.]
(Specification, 5s.; drawings, 2s.)

No. 18257.—1st August, 1904.—HILARY QUERTIER, of Wood’s Hotel, Dunedin, New Zealand, Engineer, and CHARLES CLARKE ARMSTRONG, of Dunedin aforesaid, Photographer. Improved flashlight apparatus.*

Extract from Specification.—This invention provides improved apparatus for use in producing flashlight from magnesium and other similar powders, and for collecting the smoke and other products of combustion arising therefrom. The apparatus comprises a metal chamber of any convenient shape, open at one side for the escape of the flashlight, and provided with a hood or dome into which the smoke and fumes pass. Above the hood is removably arranged an expansible receptacle for said fumes, said receptacle preferably being constructed so that it may be collapsed after the manner of an accordion when out of use, and a spring or springs is provided by which the receptacle is expanded, whereby products of combustion are drawn into it from the hood referred to.
[Note.—The above extract from the specification is inserted in place of the claims.]

No. 18274.—4th August, 1904.—ROWE’S PATENT LOCK AND BLOCK, LIMITED, a company registered according to the laws of New South Wales, Australia, having their registered office at No. 14, O’Connell Street, Sydney, New South Wales aforesaid (assignees of William Rowe, of “Mayville,” Victoria Road, Marrickville, near Sydney aforesaid, Signalfitter). Improvements in railway-traffic-control systems.*

Extract from Specification.—The nature and function of the methods and apparatus are as follows: (a.) The combination (in the excludable cabin) with revolving switching through contacts, as well understood, and the slide-bar of the instrument, of a check-bar or retaining-bolt in such a manner that the electrical switching-contacts be operated to cut out the instrument until the departure of the train from the operator’s rear section and its entry into his advance section releases the electro-mechanical lock of said slide-bar, which in turn in its locked position holds the said check-rod or retaining-bolt from movement, and so that on such release of the electro-mechanical lock the contacts may be operated to switch through the instrument circuit to cause said check-bar or retaining-bolt to retain or lock said slide-bar while the switching-contacts are in the cut-out position. (b.) The combination with said check-bar or retaining-bolt, of a similar electro-mechanical lock to that on the slide-bar,
