Abstract: PURPOSE: To perform effective cooling and purification of hot polluted air by means of a simple structure by a method wherein the process of cooling and purification of the hot polluted air by jetting the air into an mixed layer of water and aggregate and passing the same therethrough is combined with the process wherein the hot polluted air is jetted into water, while water is sprayed on the surface of the water.  
     CONSTITUTION: When the hot polluted air is jetted in and made to rise through the mixture tank 1 wherein the mixture of water 3 and aggregate 4 such as stones and pebbles is contained by an air sucking and pressurizing equipment 10 and an air jetting equipment 7, the air is cooled and purified in the rising process thereof. The polluted air cooled and purified to some degree in the mixture tank 1 is then led into an air jetting equipment 7 provided at the bottom part of a water tank 2 through an air circulating member 8 and is jetted into the water tank 2, while water is jetted from a spraying equipment 9 on the surface of the water. By this the polluted air is further cooled and purified. In this constitution, by using a plurality of mixture tanks 1 and water tanks 2 and arranging these in sequence, the primary, the secondary, the third and further coolings can be performed and thus strong cooling and and purification can be attained.

IPC: A61K8/02
Filed: 1974-11-16
Abstract: Dentifrice speckles of substantially uniform shape and size are made by agitating the material of such speckles (binder plus dentifrice component) in a liquid dispersing medium at a temperature at which the binder is liquid but undissolved and unemulsified in the dispersing medium, and cooling the dispersion to a temperature below the solidification point of the speckling material so as to solidify it into speckles of desired size. Such speckles may be separated from the dispersing medium or may remain in it and be utilized with it. Preferably the speckles are incorporated in dentifrices and contain dentifrice components desirably maintained separate from the rest of the dentifrice. Also included within the invention described are the speckles and dentifrices containing them.

Abstract: PURPOSE:To prevent a paper guide from being thermally deformed and to stably convey paper by providing a notched opening part facing the light emission part of a lamp on the paper guide and providing a recession-shaped cover on the back side of the notched opening part. CONSTITUTION:The notched opening part 5, which is provided on the paper guide 2, facing to the flash irradiation side of the light emission part 1 of the lamp has the area of opening corresponding to the maximum width of the paper 4 for a flash fixing device. The recession-shaped cover 6 mounted to be flexible in a longitudinal direction on the back side of the notched opening part 5 is formed in a V-shape inclining toward the conveying direction of the paper 4. The flash emitted from said part 1 passes the notched opening part 5 which opens to the paper guide 2 on a part facing the light emission part of the lamp and the paper guide 2 is not directly irradiated with the flash. Thus, the paper guide can be prevented from being heated with the flash and being thermally deformed and the traveling and conveyance of the paper on the paper guide can be always stably and smoothly performed.
