Abstract: ABSTRACT OF THE DISCLOSURE      A process for recovering fatty acids and/or rosin acid with a high purity which comprises first introducing a tall oil skimming soap or a tall oil soap into a thin film evaporator equipped with a rake in which the clearance between the blade tips and the surrounding evaporator wall is zero or not less than 1 mm, heating the same at a temperature higher than the melting point of the soap contained therein to evaporate and remove water and unsaponifiables, and then adding an alkali to the thus obtained crude soap to saponify the same, thereby decomposing the esters of rosin acid and fatty acids with sterols and other alcohols; or first saponifying a tall oil skimming soap or a tall oil soap with an alkali to decompose esters of rosin acid and fatty acids with sterols and other alcohols, and then introducing the thus obtained saponification product to the above-said thin film evaporator equipped with a rake, heating the same at a temperature higher that the melting point of the soap contained there-in to evaporate and remove water and unsaponifiables; followed by subjecting the resultant saponification product to acid decomposition and distillation, thereby obtaining the desired fatty acids and/or rosin acid.  In the above process, it is possible to recover not only the high purity fatty acids and/or rosin acid but also sterols by introducing, prior to the acid decomposition, the saponification product into the above-mentioned thin film evaporator equipped with a rake and then heating the same at a temperature higher than the melting point of the soap contained therein to evaporate and separate sterols and heavy unsaponfiable matters.

Granted: 1980-03-04
Abstract: LINE SEGMENT VIDEO DISPLAY APPARATUS                 Abstract of the Disclosure A raster type display apparatus includes interlaced even-and-odd frames.  A digital memory of a computer stores line segment data in locations which are sequentially read out to form a line segment display with overlapping line segments.  The first line of one field is defined by a "O" start location and a third removed location for the end.  The second line is defined by the fourth and seventh locations, and so forth.  The first line of the second field starts with the last data taken plus two to access and define the line by the second and fifth locations, and so forth.  The first field again reads the start to third locations, fourth to seventh, etc.  Data points equal to twice the scan lines are displayed with each scan line spread over four data points.  An off-scale detector prevents a line segment directly between the data points and creates a pair of line segments at the top and bottom of the display screen.  An extended line from a break point in a curve to screen bottom is also prevented.  Resettable registers monitor the carrier bits of digital multiplier and adder and are connected by an even-odd detector to actuate an exclusive "OR" gate to complement the output and generate the appropriate split display.  A display control assigns a data words as a control which are loaded in memory by the computer.  A detection network controls an "ANDED" routing network for coded control of the line segment definition, such as blanking and channel changes.

Abstract: ABSTRACT OF THE INVENTION        The duty cycle of a pulse width modulated signal for controlling a drive motor is determined by the content or number stored in a counter and representing phase and/or speed errors.  The counter is driven by a clock signal which has a number of cycles during each cycle of the pulse width modulated control signal which is exactly equal to the capacity of the counter.  The pulse width modulated signal is initiated by a timing pulse and is terminated by the return to zero of the most significant digit of the counter.  The time at which the most significant digit of the counter returns to zero in each cycle is determined by a number initially contained in the counter.  The counter of the counter is periodically determined according to detect speed and phase errors to update the duty cycle of the pulse width modulated control signal.
