No. 21297.—13th June, 1906.—LAWRENCE GEORGE WINNEKE, of McDowal Street, Roma, Queensland, Australia, Saddler. A new or improved machine for starting horse and other races.*

In machines for starting horse and other races, the use of posts normally kept upright by the springy nature of same, carrying at or near their upper ends the tapes forming the barrier, as described. and illustrated in the drawings. (2.) In machines for starting horse and other races, the use of posts (carrying the tapes forming the barrier) normally kept upright by the springy nature of same, but adapted so that they may be drawn over towards posts placed near thereto or towards the ends of brackets carried on the aforesaid posts, and temporarily retained in such position, as described, and illustrated in the drawings. (3.) In machines for starting horse and other races, the use of posts (carrying the tapes forming the barrier) normally kept upright by the springy nature of same, but adapted so that they may be drawn over towards posts placed near thereto or towards the ends of brackets carried on the aforesaid posts, in combination with means carried on such posts or brackets for temporarily retaining the barrier carried on such first-mentioned posts in a lowered position, and with means by which such barrier may be instantly released when desired, as described, and as illustrated in the drawings.

No. 21328.—19th June, 1906.—THEO EUSTACE BRIDGER, of 14 High Street, Dunedin, New Zealand, Surgeon Dentist. Improved method of and appliances for extracting teeth.*

Extract from Specification.—The object of this invention is to render a tooth and the gum surrounding it insensitive to pain so that the tooth may be painlessly extracted by the usual forceps, and so that operations on the tooth and gum may be performed painlessly, and in particular so that the grip of the forceps and the wrench of extraction are not felt, and so that there are no unpleasant after-effects. This object is effected by an apparatus which is operated to press slowly and steadily the blood away from the gums of the tooth by means of pads applied to them, which pads also keep the gums from puffing, and are controllably supplied under pressure with an isotonic saline solution which is caused by the pressure to infiltrate into the gums through the pads and so drives the blood back from the tissues not affected by the pressure of the pads. In conjunction with this apparatus there are means for injecting through a needle the saline solution supplied under pressure into the gum, which means may form part of the said apparatus used practically simultaneously therewith or which means may be a separate apparatus used separately and successively, the extraction being effected by the usual forceps suitable for the tooth operated upon.

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

No. 21451.—16th July, 1906.—JAMES ROBINSON HATMAKER, of No. 25 Rue de la Faisanderie, Paris, France, Gentleman. Improvements in drying milk and protein-containing liquids and the dry products obtained.*

Claims.—(1.) Pure dry milk of practically natural solubility and of natural acidity and taste obtained by the process of extremely short exposure described. (2.) Pure protein-containing substances in dry form and of practically natural solubility and natural acidity and taste obtained by the process of extremely short exposure described. (3.) The described process of reducing milk and other protein-containing liquid substances or mixtures to a dry conservable state which consists in exposing them in a very thin film, for a period of time less than two and one-half seconds in duration, upon a suitable drying surface heated sufficiently high to reduce them to a dry conservable state within the time of such exposure. (4.) The described process of reducing milk and other protein-containing liquid substances or mixtures to a dry conservable state which consists in exposing them in a very thin film, for a period of time less than two and one-half seconds in duration, upon a suitable drying surface heated above 212° Fahr., and as much above as may be necessary for reducing them to a dry conservable state within the time of such exposure. (5.) A modification of claims 3 and 4 characterized by this, that the heated drying surface shall be a rapidly revolving cylinder in order that the exposed film may be conveyed some little distance during its exposure upon such drying surface.
