Abstract: Abstract of the Disclosure The invention relates to a process for the preparation of .beta.-sitosterol having a low content of .alpha.-sitosterol of a sterol mixture isolated from the unsaponifiables obtained From crude soap from the sulphate cellulose process. The invention is based on crystallization of the sterol mixture from a mixture of an organic solvent and water,  preferably 1,2-dichloroethylene or methyl ethyl ketone and water. By means of the process according to the invention, from starting materials containing 20 to 25 % .alpha.-sitosterol is obtained a product which contains less than 5 % .alpha.-sitosterol and which, when required, can be retreated by means of the process according to the invention to obtain .beta.-sitosterol containing less than 1 % .alpha.-sitosterol. When using methyl ethyl ketone  as organic solvent, .beta.-sitosterol is also purified of any betulin contained in the starting material.

Abstract: APPARATUS FOR CONVERTING DATA                BETWEEN ANALOG AND DIGITAL VALUES                    Abstract of the Disclosure A plurality of output members provide a current of a particular value.  A plurality of switches or networks are arranged electrically in a matrix relationship and are connected to one another and to the output members to provide for a flow of current through a number of the output members dependent upon the binary values coded by the logic levels of binary signals.          Each logical network receives the logic levels of the binary signals coding for a particular binary significance .  The switches or logical networks provide for a current flow, with progressive increases in the binary values coded by the logic levels of the binary signals, through the output members previously providing for a current flow and provide for a current flow through additional output members with such progressive increases in such binary values.  The currents through the output members flow through a line so that the current on the line represents the analog value.  The plurality of switches and the lines providing the logic levels of the binary signals are disposed in a module or an integrated circuit chip.  A second module corresponding to the first module is also disposed on the chip and is connected to the first module to enhance the conversion between the digital and analog values.          In this way, the converter is monotonic and provides minimal amounts of differential and integral non-linearities.     * * * * * * * *

Abstract: ABSTRACT OF THE DISCLOSURE         A protective boot comprises a sole and an upper of flexible material allowing flexing of the boot, particularly when the wearer is in a crouched position.  A rigid shield is hinged to the toe of the boot and in the normal position extends over the metatarsal region.  A stirrup member has an integral base portion anchored to the sole extending under the foot of the wearer and an arch portion extending over the upper in spaced relationship thereto.  The stirrup transfers shocks re-ceived by the shield to the ground via the base portion and allows flexing of the upper under the arch portion.  The wearer can assume a crouched position in comfort without being aware of the metatarsal shield.

Abstract: ABSTRACT          This invention relates to a method and apparatus for effecting an electrotherapeutic treatment on a living body, and more particularly, to the application of an iontophoretic treatment topically to the skin of a human body.  Prior art iontophoretic treatments are known to be accompanied by undesirable effects such as the occurrence of burns in the treated area as well as the formation of undesirable vesicles and bulla, and redness of the skin in the treated area.  The present invention provides a method and apparatus for applying an iontophoretic treatment which includes conducting direct current through the skin of the body, and periodically reversing the current and conducting a relatively short pulse of current through the skin in the opposite direction.  It has been discovered that by intermittently including relatively short pulses of current in a direction opposite the direction of the normal direct current treatment, the undesirable formation of vesicles, bulla and reddening of the skin in the treated area is greatly reduced or even eliminated.

Abstract: HOME PULSE COMPENSATION FOR MULTIPLE SPEED               LINE PRINTER     ABSTRACT OF THE DISCLOSURE      The control system for a line printer includes compensation circuit means for electronically changing the timing of the reference or home pulse to compensate for changes in the speed of the type characters on a continuous type carrier.  The compensation circuit includes a storage register, a counter and a comparison circuit for comparing the content of the storage register and the counter. The counter when activated by a reference pulse generated from a reference mark on the moving type carrier counts subscan pulses generated from timing marks moving with the type characters.  The storage register, which is programmable, stores different numeric values dependent on the speed of the type carrier representing different numbers of subscan pulses to be counted by the counter means.  The comparator circuit compares the numeric value in the register with the count registered in the counting means.  When an equality is detected, the comparator circuit generates a modified reference or sync pulse which is applied to sync control circuitry which checks the character signal produced by the type position circuitry of the printer controls.

Granted: 1986-06-24
Abstract: ABSTRACT OF THE DISCLOSURE A programmable logic array is constructed of independently con-trollable logic building blocks of two types and special output logic to perform desired logic functions.  The first building block is a functional element which is capable of performing any logical function of its input data to create output data.  The functional elements shown are based on three inputs with a single output.  The second basic type of building block is a pass-through/hold device which may either pass its input directly through as an output, or which may latch and hold the input until clocked.     A plurality of logic levels or ranks of elements of the first type and ranks of the second type are interconnected so that the output can be va-rious functions of the inputs.  The logic array described here has first and second logic levels consisting of functional elements followed by a third level of pass-through/hold devices.  The fourth and fifth logic lev-els are functional elements and pass-through/hold devices.  The seventh and eighth logic levels are represented by another level of functional elements and pass-through/hold devices.  Finally, the output logic is a plurality of output enable gates connected to tri-state buffers.  The tri-state buffers may be high, low or floating.  The output enable gate functions to either cause a direct pass-through of the input logic signal or acti-vates the tri-state buffer to operate on the output logic level.  The logic array is configured and controlled by input control bits to characterize the operation of each functional element and pass-through/hold device so that it functions either to produce combinations of input logic levels or to achieve particular logic states or a combination of the two functional modes.  The output enable gates are controlled like the functional elements to either enable or disable tri-state control of the output buffers.
