Abstract: ABSTRACT OF THE INVENTION           Photochemical diodes are provided which use light to drive both endoergic and exoergic chemical reactions such that optical energy is converted into chemical energy. The photo-chemical diodes are typically suspended in a bulk volume matrix of the constituant chemical reactants. The photochemical diodes, in the form of either Schottky-type diodes or p-n type diodes, are employed, for example, to convert water into hydrogen plus oxygen (or hydrogen peroxide); to convert hydrogen sulfide into hydrogen plus sulfur; and to photo-catalyze chemical reactions.           The photochemical diodes of the invention comprises two portions, a first portion comprising an appropriately doped semiconductor material of a given conductivity and provided with an ohmic contact and a second portion comprising either metal (Schottky-type) or an appropriately doped semiconductor material of a conductivity type opposite so that of the first portion and provided with an ohmic contact (p-n type). The two portions are intimately joined together through the ohmic contact(s). Solar radiation is conveniently employed as a source of optical energy.

Abstract: ABSTRACT:        A switched-mode supply circuit whose out-put direct voltage is substantially independent of varia-tions in the input direct voltage by means of a pulse duration modulation of a controlled switch connected in series with the primary winding of a transformer.  A first rectifier connected to a first secondary winding of the transformer conducts during the out off period of the switch whereas a second rectifier connected to a second secondary winding of the transformer conducts during the conduction period of the switch.  A load is coupled to both rectifiers so that the output voltage across the load is the sum of the first and second direct voltages derived from the first and second rectifiers, respectively, the second voltage being greater than the first voltage.  This permits a substantial reduction in size of the transformer and a tighter coupling between the windings thereof.

Abstract: ABSTRACT           Heat activated, fabric conditioning products are made by impregnating a thick, absorbent substrate with fabric-conditioner chemicals.  Such products are designed for use at elevated tem-peratures encountered in laundry dryers.  This invention provides a process for impregnating the substrate with liquid fabric conditioning chemicals.  By limiting the volume of impregnate in contact with the substrate during compression of the substrate in a nip, precise control is obtained over both the quantity of impregnate and the uniformity of the impregnate in the substrate. It is critical that the volume of impregnate available at the nip be limited to a volume equal to or less than the apparent void volume of the substrate when compressed to a thickness equal to the nip gap.

Abstract: ABSTRACT OF THE DISCLOSURE      An airport complex comprising a main multi-level passenger terminal having peripheral gates for the enplaning and deplaning of passengers and cargo.  A cargo building which is disposed in close proximity to the passenger terminal greatly shortens the time factor which usually is involved in transporting cargo to and from the passenger terminal.  The airport complex is designed principally to accommodate ultra large aircraft of the jet-propelled type and novel facilities are provided for routing enplaning cargo on a priority basis from an arriving jet to a departing jet through cargo-handling facilities which are disposed within the passenger terminal, and also for routing enplaning cargo from the cargo building to a departing jet through the passenger terminal, likewise on a priority basis.  Novel facilities are also provided for routing deplaning cargo from an arriving jet to the cargo building for various subsequent distribution, as, for example, inspection at a customs station, a sorting station, and breakdown to a flight departure as enplaning cargo via the passenger terminal, or as terminating cargo for remote delivery in the environs of the airport complex.  A principal feature of such complex resides in the use of a towline cargo-handling system which cooperates with a series of power-driven cargo conveyors which, in turn, cooperate selectively with elevator mechanisms whereby both enplaning and deplaning cargo may be routed variously, the entire system being computerized for programmed control thereof.  Provision is also made for the handling of baggage, mail, freight, and other items.

Abstract: ABSTRACT OF THE DISCLOSURE   A waste heat recovery system which can be attached to, and made part of, an existing thermal oxidizer-stack system, at minimum cost, without reducing the reliability of the existing oxidizer-stack system.  It comprises a conventional heat transfer means, which is connected at its input through a refractory lined first conduit, to an opening through the wall of the first stack of the thermal oxidizer-stack system.  The outlet of the heat exchanger is connected through a second conduit to an induced draft means, which can be a conventional blower, the outlet of which is connected to a second stack.  The action of the induced draft blower is to cause inflow of hot stack through the first conduit and through the heat exchanger and to pass the cooled stack gases out the second stack.          A first temperature sensor is placed in the stack between the inlet from the thermal oxidizer and the opening where the gases are drawn into the first conduit.  A second thermal sensor is placed in the first conduit.  A differential temperature controller is provided responsive to the first and second thermal sensors and the rate of flow of hot gases the waste heat recovery system is controlled by the differential temperature.

Abstract: Abstract of the Disclosure An armored vehicle is provided with a gun mounted upon its top dock which gun is capable of rota-tion through 360° about a vertical axis.   The gun is also simultaneously elevatable through an angle of about 70°.  Located upon the deck are a plurality of barriers (some fixed and some conditional, e.g., opened hatches) which the gun must avoid during its rotational movement The apparatus of the present invention includes a programmable read-only-memory which stores the location and height of each of the barriers on the dock   A computer  continuously checks the position of the gun against the location of each of these barriers and pro-vides signals which prevents the gun from moving into forbidden zones which include the locations of these barriers.   As the gun approaches any of the barriers a signal is generated which causes  the gun to be elevated from its normal path (if necessary) and lifted over the barriers.  The distance from the barrier at which the upward movement  of the gun starts is determined by the speed of movement of the gun, the elevation of the gun, and the height of the barrier.   Thus, if the gun is moving slowly and the barrier is relatively low the gun can be moved very close to the barrier before any lift-ing of the gun occurs.  If the gun is moving more rapid-ly, or if the barrier is relatively high, the upward movement of the gun is started at a greater distance from the barrier so that the gun can be lifted over the barrier without inhibiting the horizontal rotational movement of the gun.  The apparatus includes means for -1a-inhibiting the firing of the gun when the gun control system takes over.                      -1b-

Abstract: ABSTRACT OF THE DISCLOSURE             A thermal energy scavenger assembly including a plurality of temperature-sensitive wires made of material which exhibits shape memory due to a thermoelastic, martensitic phase transformation. The wires are placed in tension between fixed and movable plates which are, in turn, supported by a pair of wheels which are rotatably supported by a housing for rotation about a central axis. A pair of upper and lower cams are fixed to the housing and cam followers react with the respective cams. Each cam transmits forces through a pair of hydraulic pistons. One of the pistons is connected to a movable plate to which one end of the wires are connected whereby a stress is applied to the wires to strain the wires during a first phase and whereby the cam responds to the unstraining of the wires during a second phase. A housing defines fluid compartments through which hot and cold fluid passes and flows radially through the wires whereby the wires become unstrained and shorten in length when subjected to the hot fluid for causing a reaction between the cam followers and the cams to effect rotation of the wheels about the central axis of the assembly, which rotation of the wheels is extracted through beveled gearing. The wires are grouped into a plurality of independent modules with each module having a movable plate, a fixed plate and the associated hydraulic pistons and cam follower. The hydraulic pistons and cam follower of a module are disposed at ends of the wires opposite from the ends of the wires at which the same components of the next adjacent modules are disposed so that the cam followers of alternate modules react with one of the cams and the remaining cam followers of the remaining modules react with the other cam. There is also included stress limiting means in the form of coil springs as-sociated with alternate ends of the wires for limiting the stress or strain in the wires.
