Claims.—(1.) The application of the commercial preparation known as Turkish bird-lime, made from the berries of the Mikssass tree (Cordia Myxa), which, when placed in the air-tube of a pneumatic tire or the like, or elastic tubes, or rubber articles inflated by air or gas substantially as described, will instantly seal any puncture or punctures already or thereafter made therein, thus preventing such air-tube of a pneumatic tire or the like, or elastic tubes, or rubber articles inflated by air or gas lapsing into a deflated state. (2.) The method and means substantially as described of dissolving and applying the commercial preparation known as Turkish bird-lime, made from the berries of the Mikssass tree (Cordia Myxa), to the air-tube of a pneumatic tire or the like, or elastic tubes, or rubber articles which may be inflated by air or gas, and so preparing any such air-tube of a pneumatic tire or the like, or elastic tubes, or rubber articles when inflated by air or gas to seal any puncture or punctures already or thereafter made therein, and so preventing the said air-tube of a pneumatic tire or the like, or elastic tubes, or rubber articles lapsing into a deflated state.

No. 20851.-14th March, 1906.-KENNETH DE LACY CUDMORE, of “ Tara ” Saltern, Queensland, Australia, Gra-zier. Improvements in rotary motors, applicable more particularly to sheep-shearing machines.

Extract from Specification.—My invention consists in providing a disc with plates working within slots in such a manner that as the disc rotates the said plates fly out by centrifugal force and, engaging the casing of the cylinder, form thereby vanes against which the compressed air impinges and expands. The eccentric disc is thus given a rotary motion, and, being attached to a spindle, is adapted to perform the operative function required.

[NOTE.—The above extract from the specification is inserted in place of the claims.]

Claims.—(1.) As a new composition of matter for purposes as indicated, the solution containing chloride of sodium, permanganate of sodium, and lime, all in combination, dissolved in substantially pure water, the amount of the chloride of sodium preponderating very greatly over that of the other ingredients in the water, and the amount of the lime preponderating over the amount of permanganate, as described. (2.) The new composition of matter for purposes indicated, comprising lime, 30 to 40 grains; permanganate of sodium, 12 to 18 grains; and chloride of sodium, 12 to 18 ounces; or substantially these proportions dissolved in two gallons of water as aforesaid.

(Specification, 3s.)

No. 20946.-3rd April, 1906.-WILLIAM TURNBULL, of 71 Lambton Quay, Wellington, New Zealand, Architect. Improvements in flushing-valves for water-closets and the like.*

Claims.—In a quadruplex telegraph circuit having a receiving sounder in a local operating circuit and a non-polar relay in the main line through the medium of which the main-line current operates the local circuit to produce signals on the sounder, the combination of electrically actuated means in the local circuit controlled by the main-line relay and operating to hold the local circuit closed on the sounder in the periods of reversal in the large-volume main-line current without affecting the normal action of the main-line relay upon the sounder. (2.) In a telegraph circuit, the combination with the main-line relay and its armature through which the incoming main-line current controls the local operating circuit of the receiving instruments to actuate the same of electrically actuated means in the local circuit operating to produce vibrations of the main-line relay armature during the time the main-line current is acting.
