Abstract: The invention deals with a process for the surface halogenation of polymeric or metallic materials. 
<??>This process comprises:
 introducing the material into a chamber;
 heating the chamber and the material to a selected temperature in the range of 38 DEG C to 93 DEG C by recirculating the air through a heat exchanger; evacuating the system; introducing a halogen into the system in an amount (i) of up to about 10 percent in excess of the theoretical amount of halogen required to halogenate the material to a desired depth and (ii) sufficient to provide a partial absolute pressure in the system in the range of 0.007 x 10<5> Pa to 0.21 x 10<5> Pa absolute;
 introducing an inert gas into the system in an amount sufficient to provide a total pressure in the system of about one atmosphere;
 maintaining the selected temperature by recirculating the halogen/inert gas mixture through the heat exchanger;
 recirculating the halogen/inert gas mixture a sufficient number of times to reduce the amount of halogen to less than about 5 percent of the amount of halogen initially introduced into the system;
 evacuating the system;
 introducing air into the system to provide about atmospheric pressure; and
 removing the material.

Abstract: An internal circulation type fluidized bed boiler in which a fluidized bed primary combustion chamber is formed by providing above the portion of an air distributing plate from which the air having a higher mass velocity is ejected an inclined partition wall which is adapted to intercept an upward flow of the fluidization air ejected from this air ejection portion, and turn this upward flow of the air toward the position above the portion of the air distributing plate from which a gas having a low mass velocity is ejected, with a heat recovery chamber formed between the inclined partition wall and a furnace wall. The inclined partition wall is formed so as to have an angle of inclination of 10 DEG -60 DEG  with respect to a horizontal plane, and a horizontal projection length of 1/6-1/2 of the horizontal length of the furnace bottom. The method of controlling this fluidized bed boiler consists of the steps of controlling the quantity of heat recovered from the heat recovery chamber in compliance with the request by the users of recovered heat by suitably regulating the flow rate of the air ejected from a diffuser for the heat recovery chamber, and controlling the feed rate of the fuel supplied to the fluidized bed primary combustion chamber, on the basis of the temperature of the fluidized bed primary combustion chamber.

Title: Method for displaying kanji characters
Inventor: SCHILLER STEPHEN N
IPC: G09G5/24
Filed: 1990-05-11
Granted: 2001-05-01
Abstract: This invention relates to a method for displaying characters on a screen or printer, particularly kanji characters.      The structure of the character is represented by stems and counters, bath vertical and horizontal, the counters being the spaces between stems. The character is then transferred from character to display space. Either the horizontal or vertical counters are grouped into a first chain of counters. The non-integral counter widths of this chain are adjusted in relation to the other counter widths within the chain, selected counter widths being made equal to others within the chain in order to most faithfully reproduce the desired character. The remaining horizontal or vertical counters, if any, are also grouped into one or more series of chains which are also adjusted, chain by chain. Then the orthogonal set of counters are adjusted in the same way. The widths of the stems themselves may also be adjusted to more faithfully represent the character in the scale at which it will be displayed.
