Abstract: METHOD OF OPERATING AN ELECTROLYTIC CELL               Abstract Disclosed is a method of electrolyzing sodium chloride brine in an electrolytic cell having a coated metal anode in the anolyte compartment and a catholyte compartment separated from the anolyte compartment by an asbestos diaphragm.  The method of this invention involves forming an anolyte liquor substantially free of resinous organic compounds solubilized from graphite anodes and cementitious compounds of alkaline earth metals solubilized from concrete structural members, imposing a hydrostatic head on the anolyte liquor while simultaneously passing an electrical current from the anode to the cathode and maintaining the anolyte liquor chlorate ion content within satisfactory limits by adding a limited amount of asbestos to the anolyte liquor over extended periods of electrolysis.  According to the disclosed method, asbestos is added to the anolyte chamber of the cell at a rate of asbestos addition high enough to maintain a low chlorate content and low pH in the anolyte liquor, but at a low enough rate to maintain a low hydrostatic head between the anolyte chamber and the catholyte chamber.

Abstract: Abstract A method is disclosed for  manufacturing novel electrolytic cell diaphragms which are consolidated by a fluorinated polymer resin. The method comprises agitating a suspension of asbestos fibers in water, a sulfonic anionic surfactant, a fluorinated polymer resin latex and a solid mineral pore-former, to form a stable, homogeneous suspension, depositing and filtering the suspension on a grid or screen to produce a preform.  The preform is dried, sintered at a temperature above the crystalline melting point of the fluorinated polymer resin, and the solid  mineral pore-former is removed to form a uniform, porous membrane having uniform pore size.  This membrane is combined with a reinforcing element by integrating the reinforcing element with the anode face of the membrane.  The reinforcing element has a structure which is at least as open with respect to the passage of liquor as the porous membrane. The novel diaphrams are particularly useful in the electrolysis of alkali metal chlorides.

Abstract: AN IMPROVED RECEIVER VOTING SYSTEM     ABSTRACT     An improved receiver voting system is disclosed in which the lowest noise audio signal produced by a number of different radio receivers is selected and coupled to a monitoring speaker.  Each receiver receives signals from a transmitter and produces either corresponding audio signals or squelch indicating status tones which are then trans-mitted to a voting (selecting) control center by telephone communication lines.  The voting control center then selects the unsquelched receiver audio signal having the lowest noise level and couples this signal to a monitoring speaker.    The voting center indicates which receiver is supplying the selected signal and therefore identifies the most favorable receiver to transmitter signal path.  Parallel squelch circuits in each receiver provide for the initial selection of the strongest received signal while preventing the existence of an irritating "squelch tail". Automatic gain control circuitry in the voting control center compen-sates for loss variations between the different transmission lines coupling signals to the voting control center,  Status tone decoders in the voting control center prevent the selection of the squelch indicating status tone as the receiver signal having the lowest noise level.  The voting control center has circuitry for switching in a status tone notch filter and changing the response time of the status tone decoder whenever a squelch indicating status tone is anticipated by the control center. Each receiver produces an audio pause which precedes the production of a squelch indicating status tone, and this enables the voting control center to anticipate the status tone and to rapidly respond to its occurrence.

Abstract: ABSTRACT   Fore and aft adjuster mechanism is capable of serving as the load carrying seat belt anchorage means for a suspension seat having a large a-mount of vertical travel for isolating the occupant from shocks and vibrations and substantial horizontal travel for adjusting the position of the seat fore and aft to the position most comfortable to a particular occupant.  The mech-anism insures that the seat belt will remain of the same tautness and angular position relative to the occupant regardless of the amount of fore and aft or vertical movement of the seat.  The adjuster mechanism is positioned in-termediate the seat base and the vehicle floor and includes a pair of fore and aft guide rails on its sides anchored to the floor and a pair of slid-ing cross rails anchored to the seat base.  Cooperating locking pins on the cross rails and holes in the guide rails provide fore and aft adjustment of the cross rails on the guide rails.  The rear cross rail also carries a link on each side which is pivoted at its free outer end to the seat belt at-tachment point on the seat base.  The link allows for unhampered normal ver-tical and fore and aft movement of the seat while transferring the loading of the seat and occupant to the guide rails and floor in a crash situation.

Abstract: ELECTRICAL INSULATOR COMPRISING AN     OPEN CELL DIELECTRIC SOLID                    Abstract of the Disclosure An electrical insulation system includes a new and improved monolythic, polymeric, porous, open cell, fully impregnable, dielectric solid and an impregnating substance that may be applied to the dielectric solid either at the factory prior to shipment or in the field prior to or during installation.  The dielectric solid is preformed to enable the quick and easy field installation of the insulation system in electrical apparatus.  In addition, the porous, open cell nature of the dielectric solid in which very small communicating open cells are substantially evenly distributed throughout substantially all of the dielectric solid enables a dielectric fluid, such as a dielectric oil, to pass through the dielectric solid and thereby impart the self-healing characteristic of impregnated layered paper insulation to the new and improved insulation system.  In a fluid dielectric system, the impregnating substance may be a dielectric oil or other dielectric liquid.  In a solid dielectric system, the impregnating substance is used to fill the open cells or voids throughout the dielectric solid and may be an initially low viscosity dielectric liquid that is inserted into the dielectric solid along with an immobilizing agent and subsequently transformed by chemical reaction into a dielectric gel immobilized within the dielectric solid.  The dielectric solid may be formed in accordance with either a sintering process or with a filamentizing process.
