347 results about "Double bottom" patented technology

A double bottom is a ship hull design and construction method where the bottom of the ship has two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is somewhat higher in the ship, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks.

Preparation of artificial pit mud for improving aged aroma of aroma type white spirit

ActiveCN101503655AComfortable scentReach functional levelAlcoholic beverage preparationSodium acetatePeat
The invention discloses an artificial pit mud preparation method capable of improving the stale flavor of highly-concentrated fragrance white spirit, which comprises the following steps: mixing qualified bran, water, yellow water and sodium acetate in a proper proportion, and filling the mixture in a fermentation tank for sterilization; and when the temperature of the materials in the fermentation tank drops to 36 DEG C, adding a proper amount of aged pit mud and a Daqu drug into the fermentation tank, uniformly mixing the material and the aged pit mud and the Daqu drug, adjusting the pH value, covering the surface of material liquid with grease for isolating the material liquid from oxygen, standing the materials in the fermentation tank at 32 to 35 DEG C for anaerobic culture for 72 hours, taking out a bacterium solution, adding yellow mud, peat, vinasse squeezed fluid, the Daqu drug, pit surface mud and bean dreg powder in a proper proportion into the bacterium solution, culturing the mixture at room temperature for 7 to 10 days after uniform mixing, grinding bacterium mud, adding a certain amount of double bottom grains, the Daqu drug and ending beer, stacking the materials after uniform mixing for natural fermentation at normal temperature for 30 to 40 days, and obtaining the artificial pit mud. The 'aging degree' of the artificial pit mud is the same as that of aged pit mud naturally aging for more than 10 years, and the stale flavor of the freshly brewed liquor is the same as that of white spirit stored for more than three years in a ceramic jar.

Process for producing alkali free glass and alkali free glass plate

To provide a process for producing and alkali free glass for effectively suppressing bubbles, and an alkali free glass produced by the process, which is suitable as a glass substrate for flat panel displays and has few bubbles.
A process for producing an alkali free glass containing substantially no alkali metal oxide, which comprises melting a glass starting material having a matrix composition of the following composition, and subjecting the molten glass to a treatment process of removing bubbles under reduced pressure, stirring or transferring under a condition where the molten glass is in contact with a platinum member, wherein the starting material is prepared so as to contain SnO2 in an amount of from 0.01 to 2.0% per 100% of the total amount of the above matrix composition; the starting material is melted under heating at from 1,500 to 1,650° C.; then bubbles contained in the molten glass are permitted to rise to the surface of the molten glass, together with oxygen bubbles generated by a reduction reaction in which SnO2 in the molten glass is reduced to SnO; and in the above treatment process, the oxygen bubbles generated at the interface between the molten glass and the platinum member are permitted to be absorbed by an oxidation reaction in which SnO is oxidized to SnO2, under a condition where the molten glass is from 1,300 to 1,500° C.
