Abstract: ABSTRACT OF THE DISCLOSURE      Photoelectrochemical cell structures and methods of fabrication are disclosed which provide for easily manufactured efficient energy conversion devices.  The structures incorporate one or more chambers for the electrolyte, and utilize semiconductor photoelectrodes.  In the plural chamber structure, the semiconductor may be opaque, and need not necessarily be a thin film.  Specific dopants for the semiconductor provide for decreased dark current and increased open circuit voltage.  Post deposition treatment is disclosed for the semiconductor to provide an increased shorting current.  Increased sputtering . wattage is provided to increase the short circuit current available from the cell.  An electrolyte composition is described having improved performance at high light intensity.      In a multi-chamber embodiment, the electrode placement causes the photoactive site to be at an end of the chamber removed from the irradiation window, thereby permitting the use of non-transparent photoelectrodes.      A third embodiment is disclosed including two photoelectrodes, in combination with a properly selected electrolyte, to provide response to two different portions of the spectrum at an increased operating efficiency.          A method and apparatus is disclosed for utilizing a photo-electrochemical cell of the type provided in a dual role, both for electrical conversion of impinging radiation and for heat utilization resulting therefrom.      Finally, a multi-chamber, multi-electrolyte structure is disclosed providing electrical charge storage after termination of radiation.

Abstract: ?BC-140 APPARATUS FOR DUMPING AND COLLECTING CORROSIVE SUBSTANCES FROM AUTOMOTIVE BATTERIES     Abstract of the Disclosure A novel battery dumping apparatus is described which is uniquely suited for dumping corrosive substances, such as battery acid, simultaneously from a number of batteries.  The novel apparatus generally comprises a sealed tube adapted for rotation through an arc of less than 360 degrees for inverting batteries contained therein.  Novel sealing and pouring means disposed at opposite ends of the tubular member provide for safe collection of the dumped corrosive liquids.  Four inflatable members of novel construction are appropriately positioned within the tube for the purpose of selectively gripping groups of batteries to be inverted.  The inflatable members are pressurized for engaging the batteries and are vented to an evacuated tank to release them.  A novel hydraulic piston is utilized as a safety interlock to prevent batteries in the inverted position from being released by the inflated gripping members.  Within the tube are disposed two parallel spaced apart baffles, which together form a sealed battery processing channel.          This battery processing channel is pierced by a plurality of rod disposed in a plane which bisects the aforementioned baffles.          These rods are ultimately caused to rotate in opposite directions by a gear drive disposed outside of said battery processing channel but within said tubular member. These gears are, in turn, caused to drive said rods by a pneumatic motor which is mounted outside of said tubular member.

Abstract: VENEER DRYING AND HANDLING Abstract of the Disclosure A heated metal plate drying system for drying either green veneer or partially dried veneer can have a plurality of modular hot presses mounted on a frame. At a loading station, individual sheets of veneer to be dried or redried are fed into a hot press, and at an unloading station the dried veneer sheets are unloaded from the system. Within each individual modular hot press, a direct contact drying process occurs that functions to reduce the moisture content of a veneer sheet down to the desired uniform level such as within a range of from 1 to 10%. The drying process accepts veneer of different species, thickness, and beginning moisture contents and the controlled process variables include contact time, temperature and pressure. Each individual modular press can be multi-opening and has the ability to open and close on command. Specially designed heated metal plates are part of each press and each plate has substantially parallel grooves on at least one surface. The modular presses are mounted on the frame such that they may be tilted at the unloading station to facilitate unloading of the dried veneer sheets. At the loading station, a loading apparatus functions to sequentially feed individual veneer sheets into the openings. The loading apparatus is pivotally mounted. Also provided is an aligning apparatus for ensuring proper alignment of each veneer sheet within its respective opening after being loaded. The modular presses in one embodiment are mounted on a carousel frame structure that is rotatable on a main bearing so each modular press indexes past the loading and unloading stations.

Abstract: D-22,240 A FLOATING GYRATOR   by CHRISTOPHER R. HUNTLEY                        ABSTRACT OF THE DISCLOSURE            A network simulating an ungrounded inductor includes an active gyrator circuit which employs an operational amplifier, said gyrator being a two port device having an ungrounded port, and a grounded port.  The ungrounded port is terminated in a capacitor C so as to provide an input impedance, Zin, looking into the grounded port, which simulates an inductor:  Zin =   = j.omega.R2C, where .omega. = 2.pi.f, e] is the voltage across the port and i] is the current into the port.  A current i2 is developed in the gyrator circuit, from the operational amplifier output, and appears as an extraneous current at the grounded terminal of the grounded port.          An active network including a second operational amplifier is connected to the active gyrator circuit and is arranged to provide current i3 which is equal in value to but opposite in sign from said i2 current.  The current i3 is combined with the il and i2 currents at the grounded terminal.  Because of its amplitude and sign the current i3 effectively cancels the i2 current. Thus, only the current il appears to pass into and out from the terminals of the grounded port and a simulated ungrounded inductor is obtained.

Abstract: ABSTRACT OZONE DISINFECTION SYSTEM A process is provided for the biological treatment of aqueous waste in a pure oxygen activated sludge/ozone disinfection system as well as apparatus to accomplish the process.         In this process, the off-gas from an ozone disinfection tank, after removal of residual ozone, is blended with the pure oxygen stream needed to supply the requirements of activated sludge treatment basin and ozonation zone.  This blending of two streams is carried out either in pipe line or in a specially built (and baffled) vessel.  The combined stream is then compressed and split into two portions.  One portion of the gas is diverted to the activated sludge treatment plant.  The rest of the gas is dried to a dew point level and then fed to ozone generator.  The discharge from the ozone generator contains a small percentage of ozone and is routed to the ozone disinfection tank.  An alternate of the system, compresses the off-gas first and then combines it with pure oxygen stream.         A two bed desiccant type dryer should preferably be employed for the drying of the gas stream upstream of the ozone generator.  A required amount of pure oxygen will be used to purge the inactive bed of the dryer.         The wastewater first flows into an oxygenation basin, whereby through the action of microorganisms in the presence of an oxygen rich gas, the organics in the wastewater are converted (oxidized) into harmless compounds.  The wastewater is discharged into a settling basin, where the biomass settles to form activated sludge which is returned to the oxygenation basin.  The clarified liquid from the settling basin overflows into an ozone contact tank where the ozonated gas is introduced to disinfect the water stream.
