Improvements in biscuit-cutting machines.\n\nExtract from Specification.—Among the objects of my invention are positively to advance the carrier which feeds the sheet of material from which the biscuits or articles are cut or formed so that the carrier will move with certainty and precision; to deliver the articles fed forward by or from said carrier by withdrawing the support from beneath them, as, for instance, by effectively alternately shortening and lengthening the carrier at a delivery point thereof, and this whether said articles be arranged in staggered or non-staggered relationship ; delivering the articles to a continuously moving receiving carrier which is driven with certainty at a plurality of different speeds; when pans or other receivers are fed by the carrier, to give to said carrier a periodic forward acceleration to move the same quickly past the delivery point of the delivery-carrier to prevent the deposit of articles over or in the spaces separating the edges of adjacent pans; when articles are cut in staggered rows, to provide instrumentalities to engage certain of said articles to prevent their delivery from said carrier, while permitting other of said articles to be delivered therefrom; and to subject the sheet of dough or other plastic material to frictional action to impart a surface thereto.\n[NomE.—The above extract from the specification is inserted in place of the claims.]\n(Specification, £1 12s.)\n\nNo. 25956.—19th May, 1909.—JOSEPH WILLIAM BATES, of Hastings, New Zealand, Chemist. Improvements in or relating to account-books.\n\nClaims.—(1.) For the purpose indicated, an account-form and a blank portion separated therefrom by a line of perforations, the underside of the blank portion being covered with adhesive matter, whereby it is attached to a blank space provided therefor at the side of the leaf of the ledger, substantially as set forth. (2.) The combination and arrangement of parts comprising the improvements in or relating to account-books, substantially as and for the purposes set forth and illustrated in the drawings.\n(Specification, 3s. 6d.)\n\nNo. 25997.—28th May, 1909.—MASSEY-HARRIS COMPANY, LIMITED, of 915 King Street West, Toronto, Ontario, Canada, Manufacturers (assignees of Lyman Melvin-Jones, President of the Massey-Harris Company, Limited, and Andrew Johnston, Pattern-maker, both of 915 King Street West aforesaid). Improvements in side-delivery rakes and tedders.\n\nExtracts from Specification.—The use of a rotating eccentric frame to hold the rake-bars in position to maintain the teeth at a constant angle to the horizontal during operation, and by the provision of means for shifting the eccentric frame to adjust said angle while in motion so as to adapt the rake to handle light or heavy hay to equal advantage, it being found that no one angle of tooth is suited to all conditions. Connecting the rake-bars centrally of their length by a frame independent of the shaft driving the rake-bars so that no vibration is transmitted to the said shaft.\n[NomE.—The above extract from the specification is inserted in place of the claims.]\n(Specification, 7s.)\n\nTHE NEW ZEALAND GAZETTE.\n\nNo.26153.-29th June, 1909.-WILFRED BERTRAM THORPE, of 62 Nightingale Lane, Balham, London, England, Electrical Engineer. Improvements in or relating to electrolytic devices suitable for use as or in the construction of electricity meters, recorders, switches, and other electrical apparatus.\n\nExtract from Specification.—In an electrolytic device of the type referred to constructed according to the present invention, in order to prevent any of the gases produced by electrolysis and held in solution in the electrolyte in one end portion of the tube getting anywhere else than into the gas-collecting space or chamber, the portion of the tube extending from the electrolytic cell is closed by a piston or diaphragm that will not absorb the gases, or not to any material extent, and which is caused to make a gastight connection with the inner surface of the tube so as to prevent escape of gas, or of electrolyte, by creeping, between the piston or diaphragm and tube wall. For the latter purpose, when the piston or diaphragm is formed of a column of mercury, a fluid-tight joint between the tube and mercury can be formed by fusing into the wall of the tube one or more rings, tubes, or pieces of a metal, such as platinum, with which mercury is found to form a fluid-tight joint, and which extend completely around the inner surface of the tube. In order to prevent oxidation of the piston or diaphragm, when this is formed of mercury, the said mercury is connected to the negative pole of a source of electric energy. To prevent evolution of gas at the surface of the piston or diaphragm when this is formed by a column of mercury, and is connected, as set forth, to the negative pole of a source of electric energy the positive pole of which is connected through a high resistance to the anode in the electrolytic cell, there is placed between the mercury and anode a high resistance that will prevent any appreciable current flowing between them, and which may conveniently be formed by a fine column or thread of the electrolyte held within a capillary tube arranged between the portion of the tube forming the electric cell and that portion thereof containing the mercury column. In order that the working of the improved electrolytic device shall be unaffected by variations in temperature of the external atmosphere, in cases where this is necessary, as in the case of an electric meter, the tube is made of rigid material, for example glass, throughout, and is hermetically sealed at its ends, as in electrolytic devices for meters of a different type to that herein referred to, so that evolved gases in one end portion of the tube, and air or other gas or gases in the other end portion thereof, will, upon being simultaneously subjected to the same variation in temperature of the external atmosphere, produce, in a manner well understood in differential-air thermometers, equal and opposite pressures on the two ends of the column of liquid or equivalent located in the intermediate portion of the tube, and consequently fail to produce any movement of such column of liquid or equivalent, and consequent inaccuracy in the working of the meter, by reason of such temperature variation. Such a tube may be in the form of a bent tube sealed at its two ends, or in the form of a bent tube sealed at one end and open at the other and enclosed in an air-tight box or receptacle which forms, in effect, a closed extension of the open end of the tube, the one form being the equivalent of the other. An electrolytic device embodying the various improvements set forth can be constructed in various forms.\n[NomE.—The above extract from the specification is inserted in place of the claims.]\n(Specification, £1 15s.)\n\nNo. 26201.—7th July, 1909.—PATRICK JAMES GRIFFIN, of Denniston, New Zealand, Miner.
