摘要:
The invention relates to a method for preparing a cobaltous hydroxide with a high density and a large particle size or an alloy hydroxide of cobalt and some other metal, in which a complexing agent and hydroxide ion is added to an aqueous cobalt brine or an aqueous brine of cobalt and some other metal under alkaline conditions in order to form a metal hydroxide. In this method, the complexing agent is selected so as to form an ammonium complex with the metal ion. The molar ratio of complexing agent to metal is about 0.5-3, and the pH is regulated in the range 10-13.

A wafer container (20) having a door (46) with at least one latching mechanism (50, 52), wherein the latching mechanism has a spring member (86) that holds the latching mechanism at one or more favored positions that preferably correspond to latch-open and latch-closed conditions. In a preferred embodiment, the spring member has an over-center condition that urges the latching mechanism towards the favored positions, thereby resisting unintended actuation of the latching mechanism.

The present invention provides an insulin-containing buccal spray and the preparation method thereof. The insulin buccal spray of the invention is a microemulsion having the average diameter of less than 200nm, comprising 10000u-70000u of insulin, 5-50g of soybean lecithin as absorption promoter, 20-80g of propylene glycol as cosolvent, and balanced with phosphate buffer of pH 6.8-7.8 to 1000ml, based on 1000ml microemulsion. The preparation method comprises: a) adding soybean lecithin to propylene glycol, mixing sufficiently, then adding phosphate buffer to result solution, and sonicating, thus obtaining the oil phase of the microemulsion; b) dissolving insulin in phosphate buffer; c) adding the insulin solution to the oil phase, sonicating again, thus obtaining the emulsion of the invention. The efficiency and stability of the emulsion of the invention are improved significantly, and administration of the invention is convenient.
摘要:
The invention relates to a waste heat boiler (1) with variable output, working by natural circulation. The steam/water cylinder (2) functions as a steam (7) and feed water (8) storage tank. All the exhaust gas (52) flows through the convection part (41), whereby the heat transfer surfaces are automatically cleaned due to the high flow velocity. The production of steam (7) is controlled by changing the water level (48) and quantity in the convection part (41). The basis of the control are the different heat transfer characteristics of the liquid and the steam. The steam/water cylinder (2) is connected to the lower end of the convection part (41) by means of the drain pipe (19), wherein is provided valves (20) controlling the water level (48), which may be either continuously adjustable or of the open/closed type. A separate control circuit controls the feed water level in the steam/water cylinder (2). Different feed pipe (6) and baffle (47) arrangements heat the feed water (8) and condense the steam (7).
