Notice of Requests to amend Specifications.

Patent Office,
Wellington, 19th February, 1901.

REQUESTS for leave to amend the specifications (in one case including drawings) relating to the under-mentioned applications for Letters Patent have been received, and are open to public inspection at this office. Any person may, at any time within one month from the date of this Gazette, give me notice in writing of opposition to the amendments. Such notice must set forth the particular grounds of objection, and be in duplicate. A fee of 10s. is payable thereon.

No. 10546.—29th April, 1898.—Francis Temple Page, of Pahiatua, New Zealand, Farmer. An improved wire-strainer.

The nature of the proposed amendments is as follows: To strike out the claim, and insert instead the following: “(1.) A wire-strainer comprising, in combination, a lever fulcrumed to a gripper and provided with a hook on each side of the fulcrum, and a length of chain provided with another gripper, substantially as set forth. (2.) A wire-strainer comprising, in combination, a lever fulcrumed to a gripper and provided with a short hook on one side of the fulcrum and a longer hook on the other side, substantially as set forth. (3.) In a wire-strainer, a lever provided with hooks of unequal length, and capable of being reciprocated to advance the said hooks so as to engage alternately in the links of a single chain, said lever and chain being provided with grippers for grasping the wires to be strained, substantially as set forth.”

The applicant states, “My reason for making the amendment is to more specifically set forth the matter claimed as novel in my apparatus, the claim originally filed covering matter that has since been found to have been old when the application for the patent was filed.”

No. 13196.—28th November, 1900.—John Collins Clancy, Analytical Chemist and Metallurgist, and Luke Wagstaff Marsland, Solicitor, both of Mutual Life of New York Buildings, Martin Place, Sydney, New South Wales. An improved process for the elimination of zinc from sulphide ores, and the extraction and recovery of lead, silver, gold, and other metals therefrom, and from other sulphide ores.

The nature of the proposed amendments is as follows:—

1. To strike out the words “the atmosphere,” and insert instead the words “a hot blast,” line 7, page 2.

2. To strike out the words “atmospheric air,” and insert instead the words “the oxygen of the hot blast,” line 20, page 2.

3. To insert, after the word “in,” line 36, page 2, the words “the before-mentioned muffle furnace or in.”

4. To alter “40” to “4,” line 43, page 2.

5. To strike out the word “latter,” and insert instead the words “first mentioned,” line 25, page 4.

6. To strike out the words “by electrolysing the same,” line 18, claim 1.

The applicants state, “Our reason for making the amendments is that certain errors crept into the specification whilst being written, and the present amendments are to remedy the effect of those errors.”

No. 13218.—6th December, 1900.—Thomas Daniells Mer-ton, of the Spottiswoode Refinery and Metallurgical Works, Spottiswoode, near Melbourne, Victoria, Metallurgist. An improved ore-roasting furnace.

The nature of the proposed amendments is as follows:—

1. To insert, after the words “cylinder G,” line 16, page 3, the following: “whence it will be delivered through a discharge-opening (g), which can be automatically opened when approaching the lower part of its travel by the withdrawal of a slide or valve (g¹) operated by a curved guideway (g²).

“A simple coupling device or connection may be provided for the purpose of disconnecting the slide or valve so that it will not be operated by the curved guideway (g²) at each revolution, but will remain shut until it is desired to again start discharging the contents of the cylinder, or said guide can be moved back out of the path of the valve-spindle to effect this object.”

2. To add to Figures 1, 2, and 3 of the drawings.

The applicant states, “My reason for making the amendments is that, through an oversight, the means whereby the revolving cylinder G discharges its contents were not described in the specification filed, and it is to remedy this oversight that I desire to make the proposed amendments.”
