Dispersion polyols which are liquid-liquid dispersions containing a first having a substantially Polyoxypropylene internal block having an equivalent weight in excess of about 700 Da and a high oxyethylene-content external block, and a second polyol which is a substantially polyoxyethylene polyol containing minimally 50 weight percent oxyethylene moieties. The dispersion polyols are stable and exhibit broad processing latitude when preparing hypersoft polyurethane foams. The dispersion polyols are advantageously prepared in situ, preferably in the presence of a double metal cyanide oxyalkylation catalyst.

A device for the exact manipulation of material, especially of organic material, includes a pulsed laser system with a radiation source, said radiation source being a cavity-dumped fs oscillator.

The invention provides a battery pack case, which includes a battery pack module fixing frame, a top cover, a left end cover, a right end cover and an outlet box, the battery pack module fixing frame includes a bottom plate, and side support frames are vertically arranged on both sides of the bottom plate , the two ends of the top of the two side support frames are respectively fixed together by cross beams, the two ends of the battery pack module fixed frame are respectively provided with battery protection baffles, and the outlet box is fixed on the left end of the battery pack module fixed frame near the top position , the left end cover closes and covers the left end of the battery pack module fixing frame which is located below the outlet box, the right end cover closes and covers the right end of the battery pack module fixing frame, and the top cover covers both sides of the battery pack module fixing frame and the part between the two beams . Also provided is a battery pack made using the battery pack case of the present invention. The battery pack case of the present invention has simple and novel structure, convenient installation and high strength, and the battery pack made by using the same is easy to manufacture and easy to maintain and replace.

The invention relates to a selective solar tunnel used for an external metope, consisting of a light-gathering body which can absorb thermal insulation air, a heat-absorbing plate which is arranged at the bottom of the light-gathering body, and a transparent top cover which seals the light-gathering body. Selective reflection is generated according to the difference of the solar altitude; the solar altitude is low in winter, thereby light beams are all reflected into the solar tunnel and the radiant energy of the light beams is converted into heat energy; the solar altitude is high in spring,in summer and in autumn and particularly in summer, the light beams are all reflected out of the tunnel and no heat is absorbed. The selective solar tunnel has a simple structure and low cost and hasno moving element. Various selective building elements can be conveniently and beautifully prepared by embedding a plurality of selective solar tunnels in the form of arrays into external surfaces such as building blocks, thermal insulation tiles, external wall panels and so on. A building built by application of the elements can absorb solar energy in winter, thereby the building reduces and even completely bears heating heat load; in summer, the building can be prevented from receiving solar radiation and be insulated, thereby the heat load of an air conditioner is reduced; the energy consumption of the building is greatly reduced; and the energy is saved.

The invention relates to the technical field of glutinous rice cake processing devices, and discloses a glutinous rice cake processing device based on reciprocating secondary hammering acting force and a use method. The glutinous rice cake processing device comprises a bottom plate, side plates are fixedly connected to the left side and the right side of the top of the bottom plate, a top plate is fixedly connected to the tops of the side plates, a pressing cylinder is fixedly connected to the top of the bottom plate, and left and right buffering extrusion mechanisms are arranged on the left and right sides of the inner wall of the pressing cylinder. The glutinous rice cake processing device solves the problems that in the hammering process, only single reciprocating hammering is adopted, although manpower is saved, glutinous rice cakes cannot become soft after being hammered, and meanwhile, the flexibility of the glutinous rice cakes can be damaged due to excessive force. According to the device, manual operation is simulated through reciprocating secondary hammering operation, so that manpower is saved, in the operation process, secondary slightly light hammering can be performed after primary heavier hammering, the glutinous rice cakes can become soft after being hammered through reciprocating operation, meanwhile, the flexibility of the glutinous rice cakes cannot be damaged, and the glutinous rice cakes are more attractive in the making process.
