Patent EP-0178793-A3 (EP)
Title: Automatic evaporator system
IPC: G01N1/40
Filed: 1985-09-17
Abstract: In a microprocessor-controlled evaporation/concentration system, a plurality of sample solutions are automatically successively delivered to an evaporation chamber (11,27) for evaporation and/or concentration. Each sample solution is evaporated in successively delivered slug components whereby each slug is delivered for temporary storage into one of two storage loops (22, 23) while the previous slug is transferred from the other loop to the evaporation chamber. The evaporation chamber (27) has a ceramic bottom wall (29) with known thermal transfer properties. The underside of the bottom wall is maintained at a microprocessor-determined constant evaporation temperature by an electrical resistance heater (30) and proportional temperature controller (31). Pressure in the chamber is maintained substantially on the vapor pressure versus temperature curve of the sample solution, thereby assuring a known evaporation rate. Valving (V14) controlled by the microprocessor permits automatic addition of diluent to the chamber to form a prepared solution of known concentration with the residue from the evaporated sample. The prepared sample is then automatically transferred to one of multiple storage vials (41) which are brought into successive registration with a syringe needle assembly (44) by means of a rotatable vial storage tray (40). The microprocessor (15) automatically cleanses the entire flow system with cleansing solution and/or purging gas after each sample has been evaporated/concentrated.

Title: Light conductor
IPC: A61C19/00
Filed: 1986-02-14
Abstract: An optical wave guide used for irradiation purposes in the dental field comprises a portion (10) tapering from a mean diameter at a radiation-entrance end (13) to a relatively small diameter, an intermediate portion (11) of said small diameter and curved about 90 DEG , and a portion (12) succeeding the curved portion (11) and flaring out from said small diameter to a relatively large diameter at a radiation exit end (14) of the wave guide. Due to the fact that the curved portion (11) has a relatively small diameter it is possible also to minimize the radius of curvature of this portion without causing radiation loss. At the same time a relatively large area is obtained at the radiation-exit end (14) from which the radiation exits uniformly. The optical wave guide configured in this way is especially suitable for sealing occlusal tooth faces onto which the exit end (14) of the wave guide is flatly placed.

controller has a function of transferring figure data of 
a source area to a destination area having a portion 
contained in a drawing-enable area defined by a clipping 
rectangle having a diagonal line define by first and second 
coordinate data. The coordinate data of each word in the 
destination area is compared with the first and second 
coordinate data to detect whether or not each word of the 
destination area is contained in the drawing-enable area. 
First information is generated in response to a comparison 
result, which designates bit or bits whose data are allowed 
to be rewritten in each word of the destination area. 
Second information is generated in response to a position 
of the word of the destination area, which designates bit 
or bits whose data are allowed to be rewritten in the 
associated word of the destination area. The data of the 
bit of bits designated by both of the first and second 
information are rewritten with the figure data. Only the 
portion of the destination area contained in the drawing-­
enable area is thus rewritten with the figure data.
