Under this heading we shall publish weekly notes of same of the more prominent home and foreign patents. IMPERMEABLE PAPER COLLARS, CUFFS, ETC.—It is proposed to make these of paper which has been partially converted into vegetable parchment. It is well known that water has Uttle or no effect on paper so prepared, and colors and patterns ean be applied with the grea.test faCllity . PEESEEYING ANIMAL AND VEGETABLE SUBSTANCES, ETc.—Mr. G. W. Perry, ofMelbourne, Australia, treats the substances to be preserved as follows. They are fl.rst washed in a solution of bisulphite of lime and magnesia, and then dipped into a bomng solution of gelatin and! bisulphite. and so, when dry, the substance is coated with an air-tight covering. In order to preserve animals, without removing the skin or feathers, a hot solution of bisulphite of lime and magnesia, with the addition of ten per cent of common salt must be injected into the blood vessels as soon as the blood is drained from the body, and before the carcass has become set. The viscera may then be removed, andtheinside thoroughly cleansed and washed with the bisulphite solution. Fish, to be preserved, should be Cleansed, the viscera reraored, and then packed in barrels, fi.lled with a pickle composed of salt and bisulphite solution. Liquids, too, suoh as ale and wine, or other fermented liquors, it is said, can be preserved in. vessels, the inside of which have been washed with blsulphite.of lime and magnesia. MANUFACTURE OF SULPHURIC AciD.—This invention consists in the employment of ammonia, or carbonate of ammonia, to condense the nitric acid vapors escaping from the exit of the vitriol chambers. To accomplish this, ammonia, or carbonate ot ammonia, is caused to come in contact with the escaping fumes, either in a cone tower or chamber. The fluid , thus resulting, is again afterwards decorrposea with sulphuric acid, and the encaping nitrous fumes are returned Into the vitriol chamber for the oxidation of the sulphurous acid. The patentee of this invention is Mr. Konrad Walter, Wicklow, Ireland. MACHINERY FOR MANUFACTURING SEMOLINA AND FLOUE.-G. A. Bueh-holz, Shepherd's Bush, England.-The invention relates to a novel arrangement of apparatus for reducing hulled wheat to semolina, which apparatus by slight modifications, may be used to reduce the same to flour, the object being to effect such operations rapidly, and, when designing to manufac ture semolina, to produce it with concurrent;formation of a minimum proportion of flour or "heat dust. It is also designed to economize space in the mill by rendering the apparatus more compact than heretofore. GRINDING MILL.—G. A. Buchholz, Shepherd's Bush, England.—This invention consists in the use of pairs of grooved rollers which are nicely adjusted to their work, and are speeded so that one roller will rotate, from ve to six times as fast as the other roller, and thereby reduce by a cutting in contradistinction to a crushing action, thejripped corn into particles ol the requiredisize. TKEATING COKN FOK PANIFIOATION.—By this process corn is prepared for bread-making without I(rlnding, and it is asserted. that by it, all the nutritious portions of the grain are retained, and only the [outer pemcle is removed. The corn is first steeped in water to remove dust and foreign matter ; in this way defective grains can be removed. as they will be found floating on the surface. After steeping for half an hour. thel;water is to be run off, a.ndithe grain is introduced into a metal cylinder with rasp-like projections on its inner, side. which remove thejouter pellicle. The grain is then placed in a receptacle filled (with water, at 68 Fah., about 400 Ibs. of water being employed to about 200 lbs. of grain. so that there may.be a certain quantity of water above the grain. about 2lbs. of semi-dried yeast. and from '15 lb. to '2 lb. of glucose :havine; been previously mixed with the water, this fermentable matter acts by degrees upon the'grain, which. after about twenty or twenty-four hours immersion, is ready for fermentation as bread. having absorbed from fifty to seventy per cent ef water. The water is then drawn off. and the grain is placed in a hopper, which. by means of a distributor, causes it to pass between rollers, where it is reduced to a pasty condition. The pasty mass is then mixed with water. to which the requisite amount of salt has been added, and the dough is then made up into loaves and baked. A NEW SWEETMEAT.—It is often amusing to notice the very simple and ordinary matters which are sometimes made the subject of a patent, the following is one of them. M. Frangois Arond. of Lyons, France. has provisionally patented a method of manufacturing a veritable sweetmeat.
