Abstract: An improved method is disclosed for reclaiming volatile products and non-volatile residue through the pyrolysis of a polymeric material comprising placing the polymeric material in a reactor and establishing an oxygen deficient atmosphere in a reactor. The polymeric material is simultaneously compressed and heated to a temperature sufficient to pyrolyze the polymeric material to produce volatile products and non-volatile residue. The volatile products and non-volatile residue are subsequently removed from the reactor and collected.

Abstract: A non-toxic environmentally friendly aqueous disinfectant is disclosed for specific use as prevention against contamination by potentially pathogenic bacteria and virus. The aqueous disinfectant is formulated by electrolytically generating silver ions in water in combination with a citric acid. The aqueous disinfectant may include a suitable alcohol and/or a detergent. The aqueous disinfectant has been shown to be very effective at eliminating standard indicator organisms such as staphylococcus aureus, salmonella cholerasuis and pseudomonas aeruginosa.

Abstract: An apparatus is disclosed for adjusting the rotational position of a chair comprising a pedestal supporting a radially outwardly extending flange. A seat base is secured to the seat and adapted for rotational connection with the pedestal for enabling rotation of the seat. A plurality of notches are defined about the flange. The lever pivot is secured for accommodating for a right-handed or a left-handed operator seated in the seat. The notch pin extends from the lever for engaging with one of the plurality of notches for locking the rotational position of the seat base relative to the pedestal.

Abstract: An improved electrochromic device comprising a substrate and a first conductive layer located on the transparent substrate. An ion storage layer is located on the first conductive layer. An electrolyte layer is located on the ion storage layer with an active layer being located on the electrolyte layer. A second conductive layer is located on the active layer.

Abstract: An anti-clog device for a terminal orifice of a dispenser is disclosed for dispensing a particulate material from the terminal orifice. The particulate material clusters into aggregates larger than the terminal orifice and are prevented from being dispensed through the terminal orifice. The anti-clog device comprises an array of projections disposed about the terminal orifice for dividing the large aggregates of particulate material into smaller aggregates of particulate material for dispensing through the terminal orifice.

Abstract: An apparatus is disclosed for adjusting the rotational position of a chair comprising a pedestal supporting a radially outwardly extending flange. A seat base is secured to the seat and adapted for rotational connection with the pedestal for enabling rotation of the seat. A plurality of notches are defined about the flange. The lever pivot is secured to either a right or a left pivot mountings for pivoting the lever pivot in either a right or a left position for accommodating for a right-handed or left-handed operator seated in the seat. The notch pin extends from the lever for engaging with one of the plurality of notches for locking the rotational position of the seat base relative to the pedestal.

Abstract: A central drive personal mobility vehicle is disclosed comprising a frame having a right and a left frame mounting located in a trailing frame portion of the frame with a seat being mounted to an intermediate portion of the frame. A right and a left leaf spring extend between a proximal end and a distal end. The proximal ends of the right and left leaf springs are secured to a right and a left drive wheel assembly supporting a left and a right drive wheel. The distal ends of the right and left leaf springs are secured to the right and left frame mounting for resiliently mounting the right and left drive wheel assemblies to the frame.

Abstract: An improved seal and method of making is disclosed for sealing a filter element to a filter mounting. The improved seal comprises a bonding pad formed from a sintered matrix of randomly oriented metallic fiber. The bonding pad is disposed between the filter element and the filter mounting. A mechanical fastener coacts between the filter element and the filter mounting for compressing the bonding pad to provide a seal between the filter element and the filter mounting. The bonding pad may be heated to create a frangible seal.

Abstract: A chemical process is disclosed for extracting copper or iron (M). The copper or iron is exposed to a leaching solution comprised of a metal salt (m) such that the copper or iron (M) is solvated and the metal ion (m) is reduced according to the reaction 2m+3(aq)+M(s)→2m+2(aq)+M+2(aq). An electrolytic cell has an anion exchange membrane separating an anode chamber from a cathode chamber. The leaching solution with the solvated copper or iron is placed into the cathode chamber of the electrolytic cell. A second solution comprising a reduced state metal salt m+2 of the salt in the leaching solution is then added to the electrolytic cell anode chamber. A voltage is applied to reduce and deposit the copper Cu+2 or iron Fe+2 at the cathode and to oxidize the metal m+2 at the anode. The oxidized metal m+2 in the anode chamber is then recycled as leaching solution for solvating copper or iron.

Abstract: An apparatus is disclosed for continuously sintering a web material with a sintering furnace. An input refractory drive unrolls a refractory material from an input refractory roll and feeds the refractory material upon a furnace conveyor of the furnace. An output refractory drive removes the refractory material from the furnace and rolls the refractory material onto an output refractory roll. An input media drive unrolls the media material from an input media roll and feeds the media material onto the refractory material. An output media drive removes the media material from the refractory material and rolls the media material onto an output media roll. A hanging sensor senses the catenary hang of the media material from the input media roll.

Abstract: An apparatus and process for making a thermoelectric device for generating an electrical voltage when elevated in temperature. The apparatus comprises an array of a multiplicity of thermoelectric elements with each of the thermoelectric elements comprising a first metal component surrounded by a second metal component with a dielectric material interposed therebetween. A first connector interconnects the first metal components to form a first thermoelectric terminal. A second connector interconnects the second metal components to form a second thermoelectric terminal. A junction connector forms a multiplicity of thermoelectric junctions between the first metal components and the second metal components.

Abstract: The process of bonding a first workpiece to a second workpiece is disclosed comprising the steps of fabricating a sintered bonding pad formed from a matrix of randomly oriented metallic fibers. The bonding pad is interposed between the first and the second workpiece and the first and second workpieces are biased into engagement with the bonding pad. Heat is applied to the first workpiece to the second workpiece for transforming substantially all of the metallic fibers into a liquid for bonding the first workpiece to the second workpiece.
