process of forming barium-cyanide which consists in forming a mixture of coking-coal with barium compound, there being present in the mixture an amount of carbon in excess of that required for the formation of carbide, submitting the said mixture to a coking-heat to form a porous composition of coke having barium compound diffused through it, then subjecting the resulting material to the heat of an electric furnace to cause formation of carbide and fusion of such carbide in and on the surface of the coke, forming a porous carbide composition, then allowing the mass to cool, and subjecting the mass to the action of nitrogen or nitrogen-bearing gases while at a temperature below the fusion-point of the carbide. (6.) An electric furnace comprising means for delivering current to the furnace, a movable receptacle adapted to contain carbide-producing materials and to present different portions of such material successively to the action of the current, and gas-delivering means adapted to deliver gas to the receptacle at a definite part of the movement thereof. (7.) The process for the production of compounds of nitrogen substantially as set forth. (8.) The apparatus for the production of compounds of nitrogen substantially as described, and as shown in the drawings.

No. 12578.—4th May, 1900.—ALEXANDER THOMPSON HAUSMANN, of Masterton, New Zealand, Painter. A continuous-rein bridle.

Claims.—(1.) The substitution of the flexible yielding rubber-cased leather or chains of the continuous rein, with free action through the mouth in opposite directions, for the rigid metal bit of the ordinary bridle, substantially as described. (2.) A continuous rein, the free loop of which exercises a concentrated inward pressure upon the sensitive portions of the head, a pressure which, when exerted, renders practically impossible any obstructive or resisting motion of the horse’s head, substantially as described.
(Specification, 2s. 6d.)

No. 12587.—8th May, 1900.—JAMES SHEPHERD, of Invercargill, New Zealand, Engineer. An improved pulley-block.

Claims.—(1.) The combination with a pulley-block of an extension-piece carrying a clamping device for securing the rope when the desired position or tension of the rope has been attained, substantially as set forth. (2.) The improved block consisting of parts constructed, arranged, and operating substantially as and for the purposes set forth, and illustrated in the drawings.
(Specification, 2s.)

No. 12589.—7th May, 1900.—JOHN ROBERT PERRY, of Dunedin, New Zealand, Dredge-owner. Improvements in power winches especially designed for gold-dredges.

Claims.—(1.) In winches moved by power, especially for dredges, the combination of drums and intermediate shafts fitted with friction-wheels such as as C¹, C², arranged to move on to a friction-pinion such as C when wanted to revolve, and on to brake-blocks such as C³, C⁵, when wanted to stand, and to be clear of both when wanted to be free, substantially as shown and described, and as illustrated in the drawing. (2.) In dredge and similar hoisting- or hauling-winchcs, the combination of shafts and friction-wheels fitted with eccentric motion for allowing the drums to revolve, stop, or run freely as desired, by lever or screw action, substantially as set forth, and for the purposes indicated.

No. 12591.—10th May, 1900.—THE TROMMLITZ VOTEREGISTER COMPANY, incorporated under the laws of the State of Colorado, and doing business at 214, Opera House Block, Denver, Colorado, United States of America (assignee of George William Trommlitz, of 132, West 2nd Avenue, Denver aforesaid, Civil Engineer, and William Henry Power, of 437, West 1st Avenue, Denver aforesaid, Mechanical Engineer). Improvements in voting-machines.

Description.—This invention relates to improvements in voting-machines, the object being to provide a machine or apparatus capable of effectually performing all of the functions necessary or required in a machine of this character. In this machine provision is made for voting straight or mixed tickets at the will of the voter; for the locking of all the other keys corresponding with the candidates for the same office on the different tickets as soon as one of these keys has been pressed and the vote registered for one candidate for the said office; for the prevention of the simultaneous operation of more than one key corresponding with the same office on the different tickets; to permit the voting for several candidates for the same office when this is required by reason of the fact that the same section or political division is entitled to be represented by several officials, as in the case of County Commissioners; for voting on questions independent of the election of candidates, as, for instance, on amendments to the Constitution, the issuing of bonds, &c. Provision is also made for registering the total vote cast, as well as the individual vote for each candidate; also for unlocking the mechanism and returning it to its normal position automatically as soon as the voter leaves the booth; as well as other features.

[NOTE.—The number (40) and length of the claims in this case preclude them from being printed. The foregoing general description has been inserted instead.]

No. 12601.—12th May, 1900.—ODILON BALTZAR HANNIBAL HANNEBORG, of Uranienborgveinen, 2, Christiania, Norway, Estate-owner. Apparatus for the collection and conveying of light or heat from the sun or other sources to the cellar, basement, or other dark rooms in buildings, mines, ships, and the like.

Claims.—(1.) For the transmission of light and heat from any source to interior rooms in buildings, mines, ships, and the like, for lighting, heating, and other purposes, an arrangement characterized by a suitable ray collector or concentrator, which intercepts the rays and reflects them into a conductor, through which they either pass directly or are reflected until they either reach a light-distributor or by special devices are converted into heat, or are separated by prisms into different colours, or in other ways utilised for various purposes. (2.) An arrangement as claimed under 1, where the construction is carried out in such a manner that a mirror a, by means of a suitable mechanism, can be moved and set in such a position in relation to the source of light that the rays will be reflected into a funnel-shaped mirror f, from which the rays, either alone or by the aid of another funnel-shaped mirror g, concentric to the first one, are reflected down the conductor h to a globe i¹, and, together with a central bundle of rays directly from the mirror a, are distributed in the room. (3.) In an arrangement as claimed under 2, the adjustment of the circular mirror a, caused by said mirror being hung on pivots b in a fork c, which may be turned around its axis d in a bearing e, while the oscillation of the mirror and the rotation of the fork c is effected by the aid of the counterweight a¹ or spring by means of cords k¹, k², which may be operated by hand or by clock-mechanism. (4.) In an arrangement as claimed under 1 and 2, the employment of a piece of tube h² with a lens l and a copper plate m, which may be inserted in the light-conductor h for heating purposes as described. (5.) In an arrangement as claimed under 1 and 2, the employment of a reservoir n in combination with a lens l, which may be inserted in the conductor h for heating purposes as described. (6.) In an arrangement as claimed under 1 and 2, an angular piece of tube o with an inclined mirror p, which may be inserted in the conductor h for lighting a dark room r by aid of a divergent mirror q as described. (7.) In an arrangement as claimed under 1 and 2, the employment of a tube o with an inclined mirror p, a lens s, and a copper plate t, and which may be inserted in the conductor h for heating a room u as described. (8.) In an arrangement as claimed under 1 and 2, instead of the globe i¹, the employment of a ray-distributor i² as described. (9.) In an arrangement as claimed under 1, the ray-collector consisting in a funnel w, in which lenses x¹, x², are set, which gather the rays and throw them in a bundle of parallel rays against the mirror y, which accordingly reflects them vertically down the conductor h.
