Title: Method for drying granulated raw material for inorganic foam
Inventor: NAGAI SATORU
IPC: B01J8/10
Filed: 1990-03-15
Abstract: PURPOSE:To execute uniform drying in a short period of time and to obtain an inorg. foam board having a low water absorptivity and excellent strength by roll drying the granules formed by granulating expandable inorg. powder raw materials. CONSTITUTION:The granules for the inorg. foam having about 15% moisture content are roll dried. The roll drying refers to the process of drying the granules by heating while moving the granules and includes a method of mechanically moving the granules by using a rotary kiln and a method of rolling the granules by hot wind like a fluid bed. The granules move while rotating in the roll drying and, therefore, the moisture contg. a water soluble component moves over the entire surface of the granules as well and deposits on the surface, unlike static drying. Not only the individual granules but also the entire part of the granules are extremely uniformly dried in this way. Since this method does not involve the direct agitation of the granules by means of blades or the like, the failure of the granules and the degradation in yield are prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent erosion due to solid particles flowing in from a boiler and to minimize an erosion damage quantity by forming a diffusion infiltration process layer on the outside surface of a nozzle plate and welding divided nozzle plates together into a fixed circular ring shape in a high pressure initial stage nozzle plate. SOLUTION: A steam turbine high pressure initial stage nozzle plate 1 is arranged in a high pressure initial stage nozzle box 2. For a diffusion infiltration process of the nozzle part, single/segment type divided nozzle plates 1 are dipped in a salt bath mainly consisting of anhydrous borax, and then, diffusion infiltration process layers are formed on the nozzle plate outside surfaces. Respective nozzle plates 1 are welded together after the diffusion infiltration process so as to be formed into a circular arc with a central angle of 180 degrees. The steam flowing into a steam reservoir 3 is led to the high pressure first step moving blade 4 via the nozzle plate 1. In this way, erosion abrasion due to oxide scale in the steam can be prevented, and reliability for a long time use of the steam turbine can be improved.

IPC: B29C41/00
Filed: 1981-04-30
Abstract: PURPOSE: To obtain a heat-resistant film excellent in the uniformity of the thickness, casting a solution of a polyimide precursor to allow it to gel, restricting a liquid material on the gelled film which has adhered concurrently with the gelation to up to a specified quantity, and passing the film through a heat-treating furnace.  
     CONSTITUTION: A composition made up of a solution of a precursor of a polyimide in an organic solvent, which has been prepared from an aromatic tetracarboxylic acid dihydrate and an aromatic diamine, a dehydrating agent and/or a catalyst is prepared. After the composition is casted and allowed to gel, it is removed. At the point where the removed gelled film is about to be introduced into a heat-treating furnace, the conditions of the production are restricted such that the liquid material adhered on the gelled film surface is up to 8mg/cm 2 . While the evaporation rate of a liquid material that will be newly generated at the heat treatment is kept at least the generation rate of the liquid material, the gelled film is heat-treated to obtain the intended heat resistant-film with the opposite edges being constrained such that the width is equal to or the same as the width of the gelled film at the time of removing.
