An improved free swinging hammer mill hammer design is disclosed and described for comminution of materials such as grain and refuse. The hammer design of the present art is adaptable to most hammer mill or grinders having free swinging systems. The improved hammermill hammer may incorporate multiple comminution edges for increased comminution efficiencies. The improved hammermill hammer may incorporate multiple comminution edges for having increased hardness for longer operational run times. The design as disclosed and claimed may be forged to increase the strength of the hammer. The shape of the hammer body may be varied, as disclosed and claimed, to improve the hammer strength reduce or maintain the weight of the hammer while increasing the amount of force delivered to the material to be comminuted. The improved design may also incorporate comminution edges having increased hardness for longer operational run times.

A hydrogen generating system and a method of in situ hydrogen generation controlled on demand capable of reacting an aluminum-free metal reagent selected from alkali metals, alkaline earth metals, alkali metal alloys and blends consisting of alkali metals, alkaline earth metal alloys and blends consisting of alkaline earth metals and metal alloys consisting of at least one alkali metal and at least one alkaline earth metal, with water to obtain hydrogen and a residual reaction product comprising metal hydroxide selected from alkali hydroxides and alkaline earth hydroxide; and separating hydrogen from the residual reaction product; liquefying the metal reagent by heating to obtain liquid metal reagent under vacuum conditions; injecting the liquid metal reagent into a reactor (3) by metal reagent injecting means (7,8) and simultaneously injecting, by water injection system (13, 14, 15), a stoichiometric amount of water with respect to the amount of the liquid metal reagent being injected into the reactor (3) such that a controlled metal reagent / water ratio is maintained in the reactor (3); transferring hydrogen and the residual reaction product from the reactor (3) to separation means (4, 18); separating hydrogen from the residual reaction product; transferring separated hydrogen to hydrogen receiving means (5) and transferring the residual reaction product to metal hydroxide receiving means (6), keeping the metal reagent injecting means (7,8) water injection system (13, 14, 15), the reactor (3), the separating means (4, 18) and the hydrogen receiving means (5) free of oxygen by selectively providing a vacuum in the system.

The invention discloses a deepwater floating type oil gas platform utilizing an underwater flexible storage device. The deepwater floating type oil gas platform comprises at least one upright post and a production group block fixed on the top of the upright post, wherein the underwater flexible storage device is arranged on the upright post and comprises an annular airtight storage tank and a plurality of storage single bodies; the storage single bodies are vertically arranged and fixedly connected in the annular airtight storage tank; the annular airtight storage tank is provided with a water pipe communicated with the outside; and each storage single body is provided with a flexible soft bag and an open protecting bush, and a medium loading-unloading pipeline connected with the production group block is arranged on the flexible soft bag and is fixed on the open protecting bush. The deepwater floating type oil gas platform is safe and environmentally friendly; by storing the media by virtue of the flexible soft bags, the separation between the media and water is realized, the volume utilization rate is high, and the cost is low.

The invention discloses a platelet quantitative separation method applied to an automatic blood component separator and can provide a more optimized operation method for platelet separation. The automatic blood component separator comprises a front extrusion plate, a hanging arm, a heat sealing head and an inductive head. The separation method comprises the following steps: centrifuging series of blood collection bags containing constant plasma weight D and different red blood cell weight Gn, extruding the blood collection bags to enable a red blood cell level to reach an inductive head position, recording a front extrusion plate moving distance as an absolute distance Hn, setting extruded plasma volume D1 (D1=D-E) according to the platelet quantity demanded E, sequentially enabling the front extrusion plate to continuously extrude all the blood collection bags till the D1 volume of plasma is extruded, recording a change value relative distance delta n of each of the blood collection bags corresponding to the moving distance at the moment and enabling a corresponding relation among the blood bag specification, the absolute distance and the relative distance to form a program to guide into software for invoking during separation operation. The platelet quantitative separation method disclosed by the invention has the benefits that prepared platelet products are consistent in weight, and the platelet density difference is smaller.
