668 THE NEW ZEALAND GAZETTE. [No. 25

No. 12400.—16th February, 1900.—DAGMAR JENSEN, of Main Street, Palmerston North, New Zealand. An improved abdominal belt.

Extract from Specification.—It is constructed of textile material a, preferably of material which will give as free circulation of air as possible compatible with the purpose for which it is used. The ends of the belt are designed to be laced together by laces passed through eyelet-holes b near either extremity. A flap c under the eyelet-holes prevents the laces from chafing the body. Strips of whalebone or similar material e are sewn into the belt in different positions to cause it to keep its shape, and strips of elastic d are substituted for the textile material at each side of the belt to give flexibility. Strips of bone or similar material f are also used sewn into the front of the belt. Tapes g of soft washable material are provided to keep the belt from riding up. They are passed round the legs of the wearer, and are secured at their ends to the belt by buttons h. Buttons i are also provided for the attachment of suspenders for stockings.

Claim.—The improved abdominal belt, substantially as specified and illustrated.

No. 12425.—1st March, 1900.—ALBERT GARDNER CLARK, of 56, Carew Building, corner Fifth and Vine Streets, Cincinnati, Ohio, United States of America, Capitalist (assignee of Benjamin Sadtler, of 1234, York Street, Denver, Colorado, United States of America, Chemist). Improvements in the treatment of zinc-bearing ores containing precious metal.

Claims.—(1.) The improvement in the process of treating ores wherein zinc is combined with iron or other corrosive agents, consisting in distilling such ores in a retort wherein chemical reactions between ingredients of the ores and of the retort are excluded by the basic lining of the retort, substantially as described. (2.) The described improvement in the process of treating ores wherein precious metals are combined with zinc and iron or other corrosive agents, consisting in distilling such ores in a retort adapted to resist the action of such corrosives, thereby extracting the zinc, and thereafter treating the residue in a smelting-furnace for the recovery of the remaining metals, substantially as described.
(Specification, 5s. 6d.)

No. 12426.—1st March, 1900.—ALBERT GARDNER CLARK, of 56, Carew Building, corner Fifth and Vine Streets, Cincinnati, Ohio, United States of America, Capitalist (assignee of Benjamin Sadtler, of 1234, York Street, Denver, Colorado, United States of America, Chemist). Improvements in retorts for reducing ores and for analogous purposes.

Claims.—(1.) A retort for reducing ore and analogous purposes having a body of fireclay, a lining or coating of refractory and infusible basic material, and a sintering material between said body and coating, chemically united to each, substantially as described. (2.) A retort for the purposes set forth having a body of fireclay, with its interior and upper outer surface coated with a refractory and infusible basic material, and a coating of sintering material between the body of said retort and said basic material, chemically united to each, substantially as described. (3.) A retort for reducing ores and analogous purposes having a body of fireclay, a lining of refractory and infusible basic material, and a coating of silicate of soda between said body and lining, chemically united to each, substantially as described.
(Specification, 7s. 9d.; drawings, 3s.)

No. 12427.—1st March, 1900.—ALBERT GARDNER CLARK, of 56, Carew Building, corner Fifth and Vine Streets, Cincinnati, Ohio, United States of America, Capitalist (assignee of Benjamin Sadtler, of 1234, York Street, Denver, Colorado, United States of America, Chemist). Improvements in the process of manufacturing retorts and other refractory articles.

Claims.—(1.) The described process of manufacturing retorts, consisting of applying to the surface of the fireclay body a sintering material, capable of forming under heat a chemical bond with the adjacent fireclay and also with a basic material, applying to such sintering material a coating or lining of refractory and infusible basic material, capable of forming under heat a chemical bond therewith, and thereupon subjecting the composite resultant to heat sufficient to effect a chemical union between such sintering material and adjacent portions of the clay body and between the sintering material and particles of the basic lining respectively, substantially as and for the purpose described.

(2.) The described process of manufacturing refractory articles, consisting of applying to the surface of the fireclay body a coating of sintering material, and then a coating of refractory and infusible basic material, and subjecting the whole to heat sufficient to fuse such sintering material into said body and into the basic lining, whereby said body and lining are secured together by a chemical bond, substantially as described. (3.) The described process of manufacturing refractory articles, consisting of applying to the surface of the fireclay body a coating of silicate of soda, then a coating of refractory and infusible basic material, and subjecting the whole to a heat sufficient to fuse said silicate of soda into said body and into said basic lining, whereby body and lining are secured together, substantially as described.

No. 12456.—12th March, 1900.—HENRY JAMES KIMMAN, of 1235, Lawndale Avenue, Chicago, Illinois, United States of America, Machinist. Improvements relating to pneumatic riveting-apparatus.

Claims.—(1.) In a pneumatic riveter, a clamping-device additional to the hammer, and operating independently thereof, substantially as described, for the purpose specified. (2.) In pneumatic riveting-apparatus, forming the end of the hammer into an air-chamber, substantially as described, for the purpose specified. (3.) In pneumatic riveting-apparatus, extending the coupling-sleeve to form a cylinder, the inner wall being the outside of the hammer cylinder, and a circular clamping-device, the latter adapted to be moved forward by the admission of air into the said cylinder, substantially as described.
