Abstract: An article of furniture for sitting includes a closed frame covered by a flexible cover. The opposite sides of the frame are captured in retainers formed in counterfacing surfaces of upright support members held in spaced relation by spacer members. The opposite sides of the frame are resiliently flexible so that they can be stressed from a natural spacing to a lesser spacing without exceeding the elastic limits of the frame sides. When the frame sides are retained by the support members and those members are connected to the spacer members, the frame sides, usually constrained by a nonextensible band or by the fabric cover, possess appreciable stored energy tending to urge them apart toward their natural spacing so that the frame sides are retained securely by the support members under the weight of an ordinary person.

Abstract: A method for filling an electrochemical cell can with a pressurized liquid electrolyte solvent and/or a liquid depolarizer. The method includes disposing an electrochemical cell system within a cell can having an open end, loosely positioning means for temporarily sealing the cell can between the open end of the cell can and the electrochemical cell system, and reducing the diameter of the open end of the cell can thereby confining the temporary sealing means between the electrochemical cell system and the open end of the cell can. The pressurized liquid electrolyte solvent and/or liquid depolarizer is introduced into the cell can. After the cell can is filled some of the electrolyte solvent and/or liquid depolarizer vaporizes. The resulting gas forces the temporary sealing means into temporary sealing engagement with the narrowed end of the cell can thereby substantially preventing loss of electrolyte solvent and/or liquid depolarizer from the cell can before the cell can is capped and permanently sealed.

Abstract: A means and method are provided for applying material to a substrate. In the means and the method, material is dispensed onto belt means and the belt means brought in contact with the substrate so as to transfer at least some of the material onto the substrate. The invention is particularly adaptable to the application of a band of silicone type material to a riser of an anode to be used in an electrolytic film-forming metal capacitor, the band of silicone type material helping to protect the anode riser during capacitor manufacture.

Abstract: An open-ended continuous sintering furnace and system including means for providing a countercurrent protective gas atmosphere through a portion of the furnace and system and a substantially contaminant-free exit atmosphere throughout the remainder of the system and a continuous conveyor means of substantially solid refractory metal with notched retaining walls. The countercurrent protective gas atmosphere is provided so as to purge volatilized impurities released from workpieces past non-sintered or partially sintered workpieces. Such a flow thereby helps to prevent contamination of more fully sintered workpieces as they are cooled and exit the system. The partial countercurrent protective gas atmosphere is accomplished by multiple gas ejection means for ejecting the protective gas or by multiple sintering chambers with gas ejection between the chambers.

Abstract: A method of making porous polymer containing separators adapted for use in electrolytic electrical devices, particularly electrolytic capacitors, the separator capable of absorbing and retaining electrolyte and devices utilizing the resultant separators. The method includes the steps of loading a semi-liquid or liquid polymer containing material with at least one compound and at least one modifier material, solidifying the polymer containing material, and removing at least some of the compound to provide a porous polymer containing separator capable of absorbing and retaining electrolyte. When the separators of the present invention are utilized in electrolytic capacitors, especially aluminum electrolytic capacitors, reductions in capacitor volume without significant loss of capacitance are realized and capacitor manufacture is facilitated.

Abstract: A chair including a contoured seat supported within a boxlike base. The seat includes a peripheral tubular frame and flexible material covering the frame. The base includes a pair of spaced, upright side members having grooves formed in the counterfacing surfaces thereof to match the contour of the seat in edge profile. A pair of lateral spacer members are connected between the side members so the edges of the seat are captured in the grooves. The seat is thus suspended in the base to provide a comfortable, unobstructed sitting area.

Abstract: An intermediate precoat layer is provided for encapsulated electrical devices such as solid electrolyte tantalum capacitors. The intermediate precoat layer contains a resin material selected from the group of acrylic, styrene, cellulose acetate, polyvinyl chloride and certain epoxy type materials. The intermediate precoat layer of the present invention helps to stabilize electrical characteristics in the electrical devices such as reducing the DC leakage current in solid electrolyte tantalum capacitors after encapsulation by a protective layer.

Abstract: The process for producing anodes on fixtures comprises the following steps. A stringer with risers of film forming metal welded at right angles to the stringer is lowered into row of cavities in an elastomeric mold which have been filled with a slurry including a freezable bonding agent and film-forming metal powder. The risers are centered in the cavities. The powder slurry is frozen with the risers held in registration with the mold pattern. After solidification of the slurry the stringer is withdrawn and the frozen anodes are pulled out of the mold cavities. Predrying preferably with the risers in place prior to freezing removes excess water so that the anodes after thawing will retain their shape and have sufficient strength to withstand the limited handling necessary to transfer them to the sintering equipment.

Abstract: Porous anodes suitable for use in capacitors which involves forming moistened metal powder into a mass, freezing the moistened mass thereby bonding the metal powder together and sintering the mass to convert it to a porous pellet suitable for use as an anode for a capacitor. The anodes have a sintered density below 12 g/cc and specific capacitance of at least 2,000 uFV/g.

Abstract: A protective layer containing polytetrafluoroethylene (PTFE) is provided over the riser of an anode having a porous film-forming metal anode body to render the riser non-wetting to a solution of manganese nitrate and thereby help prevent the formation of MnO.sub.2 on the riser during the subsequent pyrolysis step in the process of making a capacitor. The protective layer also helps to prevent mechanical damage to the anode during assembly of the capacitor. The protective layer over the anode riser may be applied by means such as dipping a wetted anode in a suspension containing particulate PTFE or by masking the anode body with a liquid and then spraying the riser with binderless material containing PTFE. The preferred embodiment employs high pressure spraying of the material containing PTFE over the anode riser.
