Abstract: ABSTRACT OF THE DISCLOSURE A security validator particularly adapted for use by the blind.  The validator includes sensors testing both top and bottom portions of a note to determine its authenticity and its denomination. Upon completion of the sensing operation, a voice recording or other audible indicia is emitted, indi-cating both the denomination and validity of the note.  The invention also includes various devices for urging the note toward the sensor to assure high resolution data gathering.  Additionally, testing of the note begins on the "green edge" of the note to assure that data is gathered from proper positions along the note.

Abstract: ABSTRACT OF THE DISCLOSURE         The present process is intended for producing the ace-tals of saturated or unsaturated aldehydes particularly for pro-ducing the dimethyl acetals of acrolein and methacrolein.  The acetals are formed in the liquid phase in the presence of solid acid catalysts such as  strongly acid ion exchange resins or zeol-lites.  The reaction mixtures are extracted by means of water and by means of organic solvents which are,not miscible with water.          The acetals  formed are recovered in a simple manner and in very good yields and so are the non-reaeted components of the starting substances .

Abstract: IMAGE PROCESSING SYSTEM             Abstract of the Disclosure A dot pattern source image stored in a pattern memory is moved to a specified location in the pattern memory in an angle of n x 90°(n= 0, 1, 2, or 3) with respect to the source image.  First, area definition is made for a rectangular source area including the source image to be moved and a rectangular destination area where the source area is to be positioned after the move processing.  Then, the positions of four sides of the source and destination areas are compared to determine, for each side, whether there is a processable side region which is included in the destination area but not included in the source area.  When such a processable side region is found along one side, the image data in a corresponding region of the source area is moved to the processable side region with a specified angle relative to the source image data.  After the move processing, the source and destination areas exclusive of the move-processed portions are redefined as new source and destination areas, and similar steps are repeated.  This technique permits the use of common program control for a basic control portion of move processing regardless of whether or not the move accompanies rotation, the positional relationship between the source and the destination areas, or the rotation angle, thereby making the system simple and economical.

Abstract: Abstract of Disclosure An  air  humidifier  used  for  regulating  humidity  in  indoor spaces,  such as residential flats,  and in which the humidity has been produced by vaporizing water in a vaporizer.   The problem in existing air humidifiers is the constant need to add water and the need of other maintenance, such as cleaning. In the air humidifier of the invention,  these problems have been solved in the way that the air humidifier is connected to the water mains by means of  a pipe,   that the  water flow entering the vaporizer can be controlled with the aid of a valve, and that after the water inflow has been stopped by the valve the heat stored in the walls of the vaporizer and in the electric resistance  dries the vaporizer,   at the  same time burning out the impurities in the vaporizer.

Abstract: A system and apparatus therefor which stores and processes flexible strip materials and particularly tire manufacturing components such as the tread portion. A portable storage unit has a pair of hollow, cylindrical-shaped spools loosely supported on a pair of cradles within a frame. A pair of annular flanges adjacent the ends of each of the spool surfaces engages stop plates on the frame to retain the spools in position on the cradles when the frame is in both a vertical load and unload position and a horizontal storage and transport position. Drive units for loading and unloading the spools preferably are similar, each including a pair of expanding mandrels and a motor driven chain connected to one of the mandrels. The storage unit is placed on a carriage which is located adjacent the mandrels of the drive units by material handling equipment. The carriage is moved horizontally toward the stationery mandrels until the mandrels are inserted within the spool interiors. The mandrels then are expanded securely gripping the spools thereon. The carriage platform then is lowered allowing the spools to lift off their supporting cradles enabling the spools to be rotated freely by the mandrels for loading and unloading the strip material on or off the spools. A storage unit is loaded with extruded tire tread material in the vertical position and then is placed in a horizontal position for subsequent shipment and storage reducing the formation of imperfections in the tread which occurs if the tread is aged in the vertical stored position.

Abstract: ABSTRACT OF THE DISCLOSURE     The process selectively absorbs hydrogen sulphide from gases containing hydrogen sulphide and carbon dioxide by contacting the gas with an aqueous solution of alkanolamine in an absorber column containing a structured packing con-sisting of a number of corrugated plates arranged parallel to the column axis.  The corrugations are angled to the column axis at an angle between 20° and 70° and run in opposite directions on adjacent plates.  The structured packing effects a lower absorption of the carbon dioxide in the solvent than Pall rings or sieve trays so that only a small amount of carbon dioxide is co-absorbed with the hydrogen sulphide.
