No. 27444.—18th March, 1910.—SAMUEL WATERS, of Jefferson Street, Brooklyn, Wellington, New Zealand, Plumber. An improved shutter for flash-signalling.*

Extract from Specification.—Consists of a casing having an opening preferably elliptical in form, in which casing a pair of plates are mounted in such a manner as to overlap with each other and to cover the opening. These plates are also so mounted that they may be moved apart by the operation of a trigger and thereby to uncover such opening. The plates are kept normally in the covering position by means of a spring, so that when opened and released they will again close. The casing is provided with means whereby it may be clamped to the front of a lamp or lantern.

Drilling-apparatus.

Claims.—(1.) In an apparatus for the described purpose, the same comprising a rotatable stem casing composed of united tube sections, a drive section secured to the upper end thereof, a double tube drill section secured to the lower end of the stem casing, and means for supplying under pressure abrasive material to the cutting-edge of the drill section. (2.) In an apparatus for the described purpose, the combination with the rotatable stem casing, a double tube drill section connected to the lower end thereof, a series of temporarily filled spirally disposed openings formed through the walls of the double tube drill section, the said openings acting successively as cutting-teeth, and means for supplying through the stem casing under pressure abrasive material to the cutting-edge of the drill section.

No. 27514.—2nd April, 1910.—NORMAN JOHN DAYSH, of Carterton, New Zealand, Dairy-farmer. Milking-machine pulsator.*

Extract from Specification.—According to my invention, a cylinder communicates with the main vacuum-pipe and has a piston reciprocable by a slide-rod, or otherwise driven by any convenient means. The cylinder is in communication with the teat-qups, and the reciprocation of the piston alternately admits air through a hole in the cylinder to the annular space referred to, and opens communication between said annular space and the vacuum-pipe so that air is withdrawn therefrom.

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

Explosives formed by the addition of an alkaline-earth silicide such as calcium-silicide to explosives already complete in themselves. (4.) Explosives formed by the addition to an explosive in accordance with claim 2 of an explosive already complete in itself, with an increase in the proportion of comburent if desired.

No. 27657.—29th April, 1910.—WILLIAM JOHN NUTTALL, of Marton, New Zealand, Plumber. Improvements in or relating to counterbalancing window-sashes.*

Extract from Specification.—The means devised for this purpose consist in the use of a metal sleeve of the well-known type, through which the end of the cord to be attached to the lower sash is passed, and in which it is fastened by means of a screw or screws passing transversely through the sleeve. In this invention the sleeve is screw-threaded on its outer face and a nut is screwed on to its lower end. Attached to the upper face of the lower sash is a metal stirrup having its upper end extending transversely above the surface of the sash. The threaded sleeve is passed down through a hole in this end, and the nut is then screwed on to the lower end of the sleeve and thus engages beneath the stirrup. The degree of tension on the cord may thus be regulated by screwing the nut up or down.
