Title: A process for the production of mineral mixture for livestock
IPC: A23K40/10
Filed: 1961-09-29
Abstract: 1,009,134. Animal feed supplements. TRANATOGEN-WERK JAKOB SCHWARZKOPF KOMM.-GES. Sept. 29, 1961 [Oct. 17, 1960], No. 35120/61. Heading A2B. Livestock are fed a granulated mixture made by a process in which a dry mixture containing magnesium oxide, sodium sulphate or di-sodium phosphate, is mixed with a solution of magnesium chloride or of calcium chloride, and the resulting material is granulated. The granules, of which 50% are in the size range 1 to 3 m.m., may have coatings of, or containing, calcium oxide, magnesium oxide, magnesium phosphate, calcium carbonate, Bolus Alba, rock salt, etherial oils, sweetening or acidic substances, trace elements, vitamins such as Vitamins A, D3 and E, hormones, antibiotics and drugs. According to an example, a mixture consisting of 40 kg. di-calcium phosphate, 25 kg. rock salt, 29 kg. calcium carbonate, 5 kg. sodium sulphate and 1 kg. of trace element salt, was vigorously stirred with 19 kg. of a calcium chloride solution. To the granules of calcium sulphate formed, there was added a mixture of 2 kg. magnesium oxide and 4 kg. di-sodium phosphate. Further granulation and drying produced granules having a white, abrasion-resistant coating of magnesium phosphate. In a further example, the initial mixture included tri-calcium phosphate and di-sodium phosphate. Other examples are directed to granulating mixtures including di-calcium phosphate, sodium chloride, calcium carbonate, Bolus Alba, magnesium oxide and trace element salt (iron, manganese, copper, cobalt and iodine) with solutions of magnesium chloride and magnesium sulphate; in one procedure, the granules obtained were mixed with a mixture of magnesium oxide, calcium oxide and di-sodium phosphate in equal parts to produce, after drying, a coating of practically insoluble phosphates.

Title: A new or improved process and apparatus for the production of concentrated nitrous gases
IPC: C01B21/20
Filed: 1920-12-14
Abstract: 163,026. Norsk Hydro - Elektrisk kvaelstofaktieselskab. May 5, 1920, [Convention date]. Void [Published under Sect. 91 of the Act]. Nitrogen oxides; nitric acid.-In the absorption of dilute nitrous gases by means of solid absorption agents, and the decomposition of the resulting product to produce concentrated nitrous oxides and nitric acid, the combined process is conducted in retort-like, acid- and fire-proof vessels surrounded by gas-tight jackets capable of resisting comparatively high pressures. The hot gases before actually entering the retorts pass into the space between the jacket and the retort in order to heat the latter and thus enable either absorption or decomposition to take place. The absorbent may be such as is described in Specification 137,071 consisting of a mixture of a dry base with one or more metallic oxides, and the absorption is advantageously effected at 300-600‹ C. In one form of the apparatus shown in the Figure, the furnace gases first pass to the vessel C containing material fully saturated with nitrous gases through the valve B, but before entering the inner retort, traverse the interstices between the jacket and the retort. To facilitate the decomposition which is preferably effected at a pressure below that of the absorption, a small portion of the furnace gases is led through the valve D actually into the retort and carries with it the concentrated nitrous gases and nitric acid to the exit F. The greater portion of the furnace gases leave the vessel C by the valve G and enters the second vessel H containing fresh or de-nitrated material, after passing through the space between the retort and the jacket. The residual gases freed from nitrous gases escape through the valve I and pipe L. When the material in the vessel H becomes saturated, the circulation of gases is reversed, i.e. the furnace gases enter the vessel H and then pass on to C. The valve D may be shut off entirely, the necessary gases then entering the retort through holes in the retort walls. Alternatively the retort walls may be made porous. Instead of two vessels, a battery connected on the counter-current principle or in any suitable manner may be employed.

Abstract: 792,556. Machinery guards. FRASER & SONS, Ltd., D. Nov. 25, 1955 [Dec. 9, 1954], No. 35646/54. Class 80 (4). In a safety device wherein a movable guard (not shown) has a recess coacting with a manually-operated pivotal bolt member 7 actuating a switch 8 controlling the machine so that the machine cannot be operated unless the guard is locked in position, means are provided to prevent the guard being unlocked unless a machine element 5 is at rest. The member 7 is linked to a handle 3 through a lever 1 pivoted on a slide block 2, the block being held against a shoulder 16 by a floating latch 10 pivoted on a radius rod 13. The bolt member 7 may be spring-biased to the locking position. When the handle 3 is pulled to unlock the member 7 the initial pull moves the latch 10 bodily until it engages the machine element 5, whereafter, provided the element 5 is at rest, continued pulling of the handle 3 causes the lever 1 to pivot about the block 2 and release the bolt member 7. If, however, the machine is running, the friction between the moving element 5 and the end of the latch 10, which may carry a pad of friction material, causes the latch 10 to pivot out of engagement with the block 2 so that continued pulling of the handle 3 does not affect the member 7. The safety device is applicable to textile machines such as carding machines.

A two-stage method for shaping hollow articles of wound sheet metal, e.g. shell cases, is characterized in that a wound sheet metal blank is given an appropriate initial shape by increasing its diameter adjacent to one end, the first stage being effected by a partial constriction of this end such as to approach the final shape of the article and the second stage effecting a relatively small final deformation by internal fluid pressure. A frusto-conical blank 1 in a base 3 and having the internal diameter of its open end inset slightly greater than the desired final external diameter D is constricted at that end by a die ring 7 on a mandrel 6 to approximately its final shape. The mandrel prevents the superimposed layers of wound sheet metal from unwinding or sliding upon one another. Finally the partly shaped blank is placed in a finishing die 4 and expanded by internal fluid pressure to its final shape.
