Abstract: ABSTRACT OF THE DISCLOSURE:       Chemical biological agents to be encapsulated are dissolved or dispersed in an aqueous paste of a gel-forming polyhydroxy polymer.  Subsequent addi-tion of boric acid or a boric acid derivative at an alkaline pH converts the paste into a gel, thereby entrapping the agents in a protective matrix.  En-capsulation of biologically active compositions pro-vides a shield against hostile environments, improves safety in handling, and slows the release of such compounds to the surrounding medium.  Highly volatile liquids are protected against losses by evaporation. Encapsulation also provides protection against de-composition from exposure to ultraviolet light.

Abstract: Abstract of the Disclosure Method of orthopedic and/or orthodontic treatment comprising the steps of securing bands or the like to selected teeth (e.g., selected molars) of one jaw (e.g., the upper or lower jaw) of a patient with these bands being adapted to hold an archwire.  Then, the proper relationship of the mandible to the maxilla is temporarily established, such as through the use of temporary splints, allowing ligaments and muscles to function normally and maintaining the patient's proper mandibular and temporomandibular joint positions.  A body of pliable, hardenable material carried by the archwire is placed in the patient's mouth with the patient's mouth open and with the archwire held in place by the bands, the body of pliable, hardenable material is in register with selected teeth (e.g., the incisors) of the patient's other arch. A buccal wire is optionally provided which contacts the outer surfaces of the front teeth and is passed distal to both the cuspids or the laterals, and is imbedded in the hardenable material on the inside of the selected teeth (e.g., front incisors and cuspids)  Then, the patient closes his mouth so that with the mandible and temporomandibular joints properly positioned with respect to the maxilla, the selected teeth of the other jaw form an impression in the body of hardenable material such that after hardening of the material and after the temporary splints are removed, the impression formed in the body of the hardenable material by the selected teeth of the other jaw serves as a reference to stabilize the position of the mandible, maxilla and temporomandibular joints during an extended period of orthopedic and orthodontic treatment whereby the patient's teeth may be orthodontically moved to their optimal anatomical and physiological positions with the mandible and temporomandibular joints held in their proper position.        Apparatus for carrying out the above-described method is also disclosed.

Abstract: METHOD AND APPARATUS FOR UNIFORM INDUCTION     HEATING OF AN ELONGATED WORKPIECE            (Abstract of the Disclosure) Method and apparatus for uniformly heating a workpiece such as a sucker rod or the like having a uniform cross-section over a major portion of its length and an enlargement adjacent each end thereof.  A multi-turn inductor is coaxially disposed around a portion of an elongated workpath with the rod being longitudinally moved at some preselected rate of travel along the workpath toward the inductor entrance end.  The inductor is normally at a first level of energization adapted to inductively heat the rod major portion to some predetermined temperature as it passes through the inductor.  Sensing a preselected power absorption level by the rod as the enlargement adjacent the leading end is inductively coupled with the inductor causes the inductor to be automatically placed at a second, higher level of energization for heating the enlargement to the predetermined temperature.  The inductor then automatically returns to the normal level of energization after some predetermined time interval for inductively heating the rod major portion.  As the enlargement adjacent the rod trailing end is placed in an inductively coupled relationship with the inductor, the predetermined power absorption level increase is again sensed and the inductor is automatically switched to the higher level of energization.  The inductor energization levels and the power absorption level sensing capabilities are adjustable to accommodate different rod and feed characteristics.

Abstract: ABSTRACT    A floating-point unit constructed of at least two identical modules.  Each module contains registers for storing floating-point data, a sign and exponent processing unit for processing the sign and exponent portions of floating-point values, and a mantissa processing unit for processing the mantissa portion.  Buses allow transfer of operands from the registers to the mantissa and sign and exponent processing units and the return of the result to the registers.  Interconnections between the modules and confi-guration logic on each module enable the modules to function as a single floating-point unit.  The interconnections include connections between corresponding buses of the modules and connections between corresponding mantissa processing units.  The configuration logic is responsive to position signals indicating the module's position relative to other modules in the floating-point unit and precision signals indicating the precision of the floating-point data being processed by the unit. The configuration logic enables the exponent processing unit of only the first module, and disables those of the remaining modules.  The configuration logic further inhibits modules whose mantissa processing units are not required for processing a mantissa of a given precision from affecting the results produced by the remain-ing mantissa processor units.  In modules other than the first module, the connections between corresponding buses transfer bits normally processed by the sign and exponent processor to and from the mantissa processor of an adjacent module.
