No. 22465.—26th February, 1907.—WILLIAM GABRIEL BARGER, of 231 Franklin Street, Melbourne, Victoria, Australia, Agricultural - implement Maker. Improvements in disc ploughs.

Extract from Specification.—The object of my invention is to provide an implement which may be simply converted so as to be used as a two, three, four, or more furrowed disc plough. The rear steering-wheel is capable of being moved to or from the discs, and made fast in any predetermined position. My invention also permits of a disc being raised or lowered so that the lower or cutting edges of all the discs will be in the same plane as the ground: that is to say, if one disc be worn small, it can be lowered so that its lower edge will be on the same level as that of its larger fellow or fellows. Or, for instance, should three discs of a four-furrowed plough be worn small, they may all three be lowered to the level of the unworn or larger disc, and the bottom edges of all four discs be in a line. In addition to the foregoing, the discs may be so mounted that they may be either stump-jumping or non-stump-jumping.

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

No. 22480.—28th February, 1907.—LA SOCIETE ANONYME WESTINGHOUSE, of 45 Rue de l’Arcade, Paris, France, Manufacturers, and MAURICE LEBLANC, of Villa Montmorency, Auteuil, Paris, France, Engineer. Improvements in or relating to jet or surface condensers.

Claims.—(1.) A condensing-chamber for jet or surface condensers, having two or more compartments maintained respectively at successively increased pressures, into which, through the passages between consecutive cones, flows a portion of the vapour to be condensed, after a partial reversal of its original direction of movement, said portion of vapour giving up a part of its energy to the vapour which passes directly to the last compartment, whence the uncondensed vapour is withdrawn by the vacuum pump. (2.) A jet-condenser constructed substantially as described with reference to Fig. 3 of the drawings. (3.) A surface-condenser constructed substantially as described with reference to Fig. 4 of the drawings.

No. 22502.—4th March, 1907.—HARRY WOOD DOWNING, of Christchurch, New Zealand, Saddler. An improved stirrup.

Claim.—The improved stirrup formed by a plate of metal with or without upwardly turned ends, and having a transverse slot near each end, and a keeper upon its under side, which slots and keeper are adapted to receive a stirrup-strap, substantially as specified.

No. 22503.—4th March, 1907.—MORTIMER FREDERICK MIEVILLE, of “Summersdale,” Chichester, Sussex, England, Engineer. Improvements in apparatus for the production of carburetted air.

Claims.—(1.) In apparatus for the production of carburetted air, the combination of an aerometer for storing pure air under pressure, to which the supply of air is automatically regulated, and from which it is supplied to a carburetter consisting of separate chambers provided with adjustable valves by which a part of the pure air is carburetted and passed through a drying-chamber and a part through a drying-chamber only, the two columns of air being then admitted to a mixing-chamber by automatically controlled valves, and thence to a gasometer having a safety stop for the prevention of back-fire, substantially as described and illustrated. (2.) In apparatus for the production of carburetted air as described in claim 1, the arrangement of the pipe i from the aerometer, formed with two branches j and k, and having the valves l and m for regulating the supply of air to the carburetter, substantially as described and illustrated. (3.) In apparatus for the production of carburetted air as described in claim 1, a carburetter constructed substantially as shown in Fig. 3, and consisting of separate carburetting and drying chambers, and the separated columns of pure and carburetted air respectively passing from the carburetter through the valves s, w, to the mixing-chamber x and thence to the gasometer, substantially as described. (4.) In apparatus for the production of carburetted air as described in claim 1, the arrangement of the rods e, e, and stops h, h¹, connected with the sliding bell of the aerometer, and automatically regulating the supply of air through the valve d, substantially as described. (5.) In apparatus for the production of carburetted air as described in claim 1, the arrangement of the rods B, C, and stops E, F, connected with the sliding bell of the gasometer and automatically regulating the supply of carburetted air and pure air to the mixing-chamber x and gasometer y, substantially as described. (6.) In apparatus for the production of carburetted air as described in claim 1, the valve I fitting and closing the delivery-pipe G from the gasometer when the latter is emptied of its contents, substantially as described.

No. 22504.—4th March, 1907.—ANGELO CIPRIANO BARONIO, of 20 Copthall Avenue, London, England, Telegraphic-code Specialist (assignee of Alexander Muirhead, of the Lodge, Shortlands, Kent, England, D.Sc., F.R.S., Telegraph Engineer). Improvements in and relating to electric telegraphy.

Claims.—(1.) In a system of electric telegraphy, the employment of a plurality of voltages for the purpose of superimposing upon the received telegraphic outlines separate markings for contemporaneously indicating vowels, or other additional characters. (2.) In a system of electric telegraphy, the employment of a succession of current-impulses and a plurality of voltages in such manner that the received outlines are of varying height but equal length, and the letters of each word follow one another without the usual space between them, and whereby the number of current-impulses or time-intervals required for the transmission of communications is diminished. (3.) For use in an automatic telegraph transmitter, a strip or tape having three rows of side perforations, two of which are the ordinary signalling perforations, whilst the third or “extra” row is for the purpose of varying the voltage of both positive and negative sign applied to the telegraphic conductor and thereby producing movements of the index of the receiving instrument of varying amplitude. (4.) A telegraphic perforator having an “extra” punch adapted to be operated simultaneously with the usual “dot” and “dash” punches. (5.) A telegraphic perforator constructed or arranged substantially as described or illustrated. (6.) For the purpose of transmitting a single train of telegraphic signals, an automatic telegraph transmitter having an “extra” contact lever whose movements are governed by a strip or tape perforated with an “extra” row of holes, and whereby a different voltage is applied to the telegraphic conductor to produce movements of the index of the receiving instrument of varying amplitude. (7.) An automatic telegraph transmitter constructed or arranged substantially as described or illustrated. (8.) For use at the receiving station of a telegraphic system, a strip or tape perforated or impressed with an “extra” row of holes or markings due to a different voltage having been applied to the sending end of the telegraph conductor. (9.) For use in recording or retransmitting a single train of signals received from a telegraphic
