No. 21103.—8th May, 1906.—HARRY BAIRSTOW, of Ashburton, Canterbury, New Zealand; Cabinetmaker. Improved draught, dust, and rain excluder.*

Claims.—(1.) For the purpose indicated, links connecting a spring-operated excluder-plate to a plate fixed to the door, and means whereby the links are operated to move the excluder-plate vertically, substantially as set forth. (2.) For the purpose indicated, means for operating the links described in claim 1, consisting of a slide-bar having a bevelled end projecting from the edge of the door remote from the hinges thereof and pivoted to the said links, and a curved striking-plate secured to the door-frame, substantially as set forth. (3.) For the purpose indicated, in combination with a door, a plate fixed near the bottom thereof, an excluder-plate below the fixed plate, pivoted links connecting the excluder-plate to the fixed plate, a slide-bar between the fixed plate and the excluder-plate, and having its bevelled end projecting from the edge of the door remote from the hinge thereof, guide-pins secured to the fixed plate passing through slots in the slide-bar and entering holes in the excluder-plate, a tension-spring connecting the fixed plate to the excluder-plate, and a striking-plate upon the door-frame, substantially as set forth. (4.) The combination and arrangement of parts comprising the improved draught, dust, and rain excluder, substantially as and for the purposes specified and as illustrated in the drawings.

No. 21339.—22nd June, 1906.—LOUIS FRIEDENREICH, of Thornleigh, New South Wales, Australia, Baker. A compressed yeast and the method of the production thereof.

Extracts from Specification.—In the production of the compressed yeast there are two distinct processes involved which shall be described in detail. The first is the production of a “stock” or “mother” yeast of such a nature that the culture produced will harmonize with that subsequently resulting from the second—that is, the air-fermenting process. In the production of the “mother” yeast what is technically known as the “old system” is adopted, and the ingredients used are preferably malt, rye, and maize. These are ground into a coarse meal, mixed with water, and kept at a suitable temperature to induce fermentation. . . . The production of the merchantable (that is, the compressed-air-fermented) yeast is a much more complicated affair. In its production the following materials or their equivalents in other cereals are used in about the following proportions: Maize, 50 parts; malted barley, 20 parts; wheat, 20 parts; malt sprouts, 10 parts. . . . To the mash consisting of the bruised wheat, barley and the malt sprouts water is added in the proportion of about 3 quarts to every 4 pounds of the dry grain. The whole is blended and mixed in a suitable vat, and permitted to stand for some hours (usually over night). The maize having been thoroughly softened by steam (but not bruised or crushed) is then put into the mash, and the compound raised to a temperature of from 130° to 145° Fahr. The mash is kept moving by mechanical means in the vat at the required temperature from one to two hours, thence it is passed to the filter vat, whence the liquor is drawn off into another called the liquor-vat, and pumped thence into still another receptacle known as the air-vat, in which has been previously placed the requisite amount of the “stock” or “mother” yeast hereinbefore described. Within this air-vat is a perforated coil into which air is forced by any suitable means. The air which reaches the liquor through the coil assists the process of fermentation, and as it is important that this air should be free from all impurity, it is desirable that it should be forced through a water bath ere it reaches the coil within the air-vat. For the purpose of preventing any impurity which may be contained in the air within the room from reaching the yeast liquor at this stage a supply of oil or melted fat is provided, which when floating on the surface of the liquor within the vat prevents the air from coming into contact with the liquor. After the yeast liquor has remained in the air-vat till the culture has reached the required stage of development, which can only be ascertained by continued tests, it is drawn off into the cooling-vat and allowed to deposit. When this process of settlement is complete the fluid portion is drawn off and the yeast remains in the vat. This fluid contains the whole of the spirit generated during the process of fermentation, and will constitute a valuable by-product. The yeast, now quite free from any mixture of spirit, after being washed and pressed to any required density, preferably about that of ordinary cheese, is ready for transportation and use.
