Abstract: TITLE OF THE INVENTION             A PROCESS FOR OBTAINING PROTEIN ISOLATES                    OF VEGETABLE ORIGIN                   ABSTRACT OF THE DISCLOSURE           An easily extrudable, purified and concentrated protein can be obtained from a vegetable source, such as sunflower and colza, by subjecting an alkaline solution of the protein obtained from said source to ultrafiltration through a semipermeable membrane having a pore size of 0.1 to 30 mµ to form a retentate containing an amount of nitrogenous matter (N x 6.25) in the range of 3 to 12% by weight of the retentate, and adding a wash liquid to said solution while continuing said ultrafiltration, such that when volume of the permeate is equal to said added volume, the concentration of nitrogenous matter (N x 6.25) in the retentate will be 70 to 85% by weight of the dry matter of said retentate.          Thus-obtained retentate is further ultrafiltrated using the said semipermeable membrane, and thereafter said purified and concentrated protein is recovered.  The above process does not require such a large amount of solvents that is indispensable in conventional protein recovery processes, thereby substantially solving potential environmental pollution problem due to such enormous amount of solvents.

Abstract: ABSTRACT OF THE DISCLOSURE           An adsorption process for the separation in con-centrated form of a dissolved component from a liquid stream in which the dissolved component is present in low concentration, is described. The liquid stream is passed through a bed of adsorbent until the capacity of the bed for adsorbing the dissolved component from the liquid stream is substantially reached. Then a more concentrated solution of the dissolved component is passed through the bed of adsorbent until it is more highly loaded with the dissolved component. Thereafter an eluant is passed through the bed to regenerate the ad-sorbent and yield an eluate containing the dissolved component in high concentration.

Abstract: ABSTRACT OF THE DISCLOSURE      An electronically controlled embossing machine for embossing aplha-numeric characters on flexible sheets such as, for example, plastic or metal credit cards or nameplates.  Embossing is accomplished by two constantly rotating embossing wheels which carry radially movable embossing molds about their peripheries.  One embossing wheel carries male or projecting embossing molds; the second wheel carries matching female or intaglio embossing molds.  Selection of a certain character via a keyboard, or by electrical signals from any data source, causes the appropriate male and female molds to be moved radially out-wardly on each wheel by mechanical mold cam levers.  A flexible sheet, such as a plastic credit card blank, interposed in the bite of the two embossing wheels, is embossed by the radially extended embossing mold in a rolling-squeezing process.  After the embossing of a selected character on the flexible sheet, the previously selected embossing molds are returned inwardly to their original positions and the flexible sheet is indexed to the proper position for embossing of the next character.  An electronic system senses the instantaneous position of the embossing wheels and controls the timing of the embossing sequence including actuation of solenoids for the selection and extension of desired embossing mold

Abstract: Abstract of the Disclosure A pair of compensating wheels are carried by a print head carriage in position to ride on record media being printed and are rotatable driven by frictional contact therewith, the wheels having overriding clutches associated with their respective shafts to permit driving of one shaft and its gear in alternate manner with the other shaft and its gear.  The respective driving gear engages with a driven gear on a third shaft for rotation thereof and thereby drives the ribbon in one direction. Upon return of the print head carriage in the opposite direction, the action of the overriding clutches is reversed to permit driving of the other shaft while the first shaft and its wheel are free wheeling.  Regardless of the direction of travel of the print head carriage, the ribbon drive shaft is rotated in the same direction.

Abstract: CIRCUIT INTERRUPTING DEVICE            ABSTRACT:  A circuit interrupting device is dis-closed.  A stationary contact is mounted within a stationary hollow insulator and connected to one side of an electrical circuit.  A movable contact normally engages the stationary contact and is mounted for movement within the stationary hollow insulator.  The movable contact is connected by a contact rod that extends through an opening in the insulator to a set of spring detent fingers.  The spring detent fingers electrically and mechanically engage the end of a movable conductive element, such as a power fuse or disconnect switch-blade, which is connected to the other side of the electrical circuit.  A spring biases the movable contact toward engagement with the stationary contact.  When the movable conductive element is moved away from the device, the spring detent fingers gripping the element move therewith and cause the movable contact to move to disengage the stationary contact.  The resultant arc between the contacts is quickly extinguished by an arc extinguishing liner and trailer within the hollow insulation thereby interrupting current flow.  The movable contact continues to move away from the stationary contact until the movable contact engages a limit stop within the hollow insulator.  At this time, the spring detent fingers disengage the movable conductive element creating an air gap, and the spring returns the movable contact to engagement with the stationary contact. However, since the movable conductive element is now disengaged, current flow remains interrupted.          A latch arrangement may be provided to latch the conductive element to the device to prevent accidental opening until the latch is manipulated by an operator.

Abstract: CONTROLLABLE STATE CONVERSIONS FOR S=1 BUBBLE DOMAINS                 Abstract of the Disclosure A technique for controllably providing state conversions between bubble domains having a common winding number S is described.          In particular, controlled conversions between bubble domains having winding number S=1 is achieved by the application of spatially invari-ant, homogeneous magnetic fields.  For the conversion of .sigma. bubbles (having two vertical Bloch lines) to X bubbles (having no vertical Bloch lines), an in-plane field is not required and only a time varying perpendicular z-field is used.  For conversion of a X+ bubble to a X-bubble, and vice versa, a time varying field pulse is applied, there being no requirement for an in-plane magnetic field.  However, for the conversion of X bubbles to .sigma. bubbles, an in-plane field is used simul-taneously with a time varying z-field.  For all controlled conversions, the applied magnetic fields do not have spatial gradients.  The magnitudes of the applied magnetic fields and the rise and fall times of the z field are controlled within certain ranges in order to have con-trolled conversion of one state to another.
