Abstract: BACKFIRE-RESISTANT GAS TORCH CONSTRUCTION     ABSTRACT OF THE DISCLOSURE     The invention contemplates a gas-torch construction wherein independent flows of combustible gases are maintained up to the point of mixing within the nozzle of the torch, virtually at the location of discharge from the nozzle.  The nozzle is removably connected to an elongate intermediate or adapter member, and the latter is removably connected to the torch body.  The separate flows of the gases are maintained independent of each other, from the torch body, through the adapter member, and into the upstream end of the mixing nozzle.          Individual radially spaced manifolds at the adapter-to-nozzle connection assure independence of the gas flows and a non-critical angular relation when the nozzle is replaced.  The invention is described in application to a powder-spraying gas torch, as for torch deposition of metal coatings.

Abstract: HIGH SENSITIVITY PHOTON FEEDBACK PHOTODETECTORS            Abstract of the Disclosure Large current gains and high degrees of sensitivity to impinging primary photons are realized in photon feedback photodetectors embodying the invention. photocurrent generated by an internal photodiode in response to the primary photons causes secondary photons to be emitted by internal serially connected luminescence diodes. Secondary photons traveling away from the photodiode are redirected by a reflector to impinge on the photodiode and thereby sustain the photocurrent.  Gains of the order of 100 are realized by these photodetectors.

Abstract: HOT MELT ADHESIVE SYSTEM          Abstract of the Disclosure A hot melt foam adhesive system including a gear pump wherein gas is mixed under pressure into the molten adhesive and is driven into solution with the adhesive.  The adhesive/gas solution is supplied at a relatively high pressure to a valved dispenser or gun from whence it is dispensed onto a substrate.        As the adhesive/gas solution emerges from the dispenser, the gas comes out of solution but remains entrapped in the adhesive, thereby forming an adhesive foam.  The system includes a recycle flow line or hose for returning adhesive/gas solution from the dispenser to the pump.  Within this recycle flow line there is a pressure regulator responsive to flow changes or viscosity changes of the adhesive/gas solution for maintaining a fixed back pressure in the system, thereby enabling the system to maintain a fixed and uniform flow rate from the dispenser during all operating conditions of the dispenser.

Abstract: TITLE OF THE INVENTION:            METHOD FOR QUENCHING COKE            ABSTRACT OF THE DISCLOSURE:            Preheated bulk material capable of coking is quenched by flowing the quenching liquid through the loose bulk ma-terial, whereby the bulk material is substantially closed off relative to the atmosphere.  The liquid is applied to the top of the bulk material in a quenching chamber which is closed at its top by a sealed cover and which has an open grating for a horizontal bottom.  The steam formed by the quenching liquid and, if formed, any excess quench-ing liquid are drawn off from the quenching chamber through the open grating.  The total quantity of quenching liquid to be supplied as a function of time is controlled by a valve through a control signal depending on the chemical and physical properties constituting bulk material char-acteristics prior to the heating of the coal.  The control signal also takes into account the type of the intended heat treatment in the form of quenching characteristics.          In a surprisingly simple embodiment the valve may be con-trolled by the operation of a cam disk which has a cam sur-face shaped in accordance with these characteristics.

Abstract: ABSTRACT             It has been a problem to pellet seeds with inoculum of the beneficial VA mycorrhizal fungus.  Hitherto, clay or soil pellets have been tried but they are difficult to adjust to a suitable moisture content and the pellets are too heavy, and there is a problem in placement of the seed so as to ensure that the radicle will grow through the pellet and thereby pick up the desired fungal infection.  It has now been found that satisfactory pellets can be made using peat, preferably sphagnum moss peat, and a binder instead of soil and that even when the pellet is dried considerably the inoculum retains infectivity for at least 6 months, using sphagnum moss peat.  The composition in uncompacted and compacted forms and a method of growing plant from seed are claimed.  The invention is useful for improving the condition of poor soil, e.g. filled-in gravel pits or coal mine spoil tips.
