Abstract: ENCAPSULATION BY INTERFACIAL POLYCONDENSATION ABSTRACT OF THE DISCLOSURE This invention relates to a process for encapsulation, and particularly to the production of small or minute capsules constituted by a skin or thin wall of polymeric material e.g., polyurea, polyamide, polysulfonamide, polyester, polycarbonate, or poly-urethane, which involves first providing an aqueous solution (continuous phase liquid) containing an emulsifier which is a water soluble, alkylated polyvinyl pyrrolidone polymer which will form a stable oil-in-water emulsion under the process conditions described herein. A discontinuous (immiscible or organic) phase liquid containing a water-immiscible material which is the material to be encapsulated, plus a first shell wall component; is dispersed in the aqueous liquid to form an oil-in-water emulsion. The second shell wall component is added to the oil-in-water emulsion whereupon the first shell wall component reacts with the second shell wall component to form a solid polycondensate shell wall about the material to be encapsulated. The capsules formed may be directly used as in the form of an aqueous suspension.

Abstract: Abstract LIGHTWEIGHT BIPOLAR METAL-GAS BATTERY   A  bipolar  metal-gas  battery  cell  stack   (1) eliminates the heavy bipolar plates (11) of the prior art  by  means  of  locating  the  series  electrical connections  (25,  27)  between  oppositely  polarized electrodes  (5,  7)  of adjacent cells  (3)  external  to the cells (3)  in a dielectric frame (21, 23).  As a result, the reliability of said electrical connections (25,  27)  is improved,  weight is saved,  and reactant gas screens (15) and electrolyte reservoirs (13)  can beneficially  be  made  of  compressible  lightweight materials.    Electrolyte   is   beneficially   confined within  each  cell  (3),  and secondary  (overcharge) gasses are beneficially confined within each cell (3) in  a  region  (17)  proximate  the  positive  electrode (7).   A  hydrophobic  barrier  (29)  and  the  frame segments  (21,  23)  prevent  intercell  migration  of electrolyte and secondary gasses.

Abstract: ABSTRACT    A microscope for use in all surgical disciplines, without need for ordinary or special tools, comprising an assembly of microscope, illumination module (magnification changer), fiber optics cable to the module, a mechanical assembly to which they are connected, means for focusing the microscope, means for mounting such assembly of elements to a fulcrum axis through the mechanical assembly, and a tilt-axis ad-justable counterweight to balance the assembly, with or without addition or removal of elements, all operatively mounted to a support arm.  A second adjustable counter-weight is provided to prevent lateral or transverse tipping of such assembly when laterally extending accessories (eg., observer's tube assembly) are added or removed.  The mecha-nical assembly includes tension controls to change tilt of the microscope about the support arm, with the tilt-axis counterweight being accordingly adjusted.  The support arm is mounted to a mounting member of a ceiling, wall or other counterweight stand, either directly or through an angle coupling.  The support arm's position is swingable through an 180° arc, and when so swung, the noted mounting means is swung 180° about the fulcrum axis so that the microscope et al elements and first counterweight means remain in the same relative positions for use in surgical procedures.  A safety latching system on the focusing means sub-assembly prevents fall-out of the weighted microscope et al elements from the mounting means should the tension controls be relaxed too much.
