Abstract: Abstract of the Disclosure An improved method of gluing a package in an in-line packaging machine.  The package is of the type having a plurality of leading and trailing end flaps which are glued to be together during the packaging process.  The novel method comprises in part providing at least two glue nozzles  in  the line  of  the packaging machine direction with one glue nozzle facing downwardly and upstream while the other glue nozzle faces downwardly and downstream so that the glue is projected or sprayed onto a pair of the end flaps by one nozzle in an upwardly direction and by the other nozzle in a downwardly direction as the package is moved through the packaging machine past the glue nozzles.   Subsequently thereafter, the other pair of end flaps are turned inwardly and are held in position after being glued until the glue sets. The four flaps of the package are turned inwardly by a first and a second flap closing means.

Abstract: SUPPORT FOR COLLAPSIBLE DRAG REDUCER          Abstract of the Disclosure A support mechanism for moving a roof top pivotally mounted air deflector panel between raised and lowered positions includes a collapsible toggle linkage having a support link and a pivot link.          The pivot link is pivotally mounted on the cab rear wall and has a handle by which an operator stand-ing on the tractor at the rear of the cab pivots the pivot link between   vertically upright extending and downward extending positions.  A support link has an upper end pivotally connected to the deflector panel and a lower end pivotally connected to the pivot link so that rearward pivotal movement of the pivot link swings the lower end of the support link rearwardly and downwardly to withdraw the support link from support of the air deflector panel.  The collapsible toggle linkage stores adjacent the cab rear wall for ready handle access by the operator for subsequent raising of the deflector panel.  A telescoping spring device acts between the cab roof and the deflector panel to assist upward pivotal movement of the pivot link and extension of the col-lapsible toggle linkage to raise the deflector panel.            A releasable latch is provided to retain the col-lapsible toggle linkage in both the extended and collapsed positions.  A pair of such collapsible linkages are preferably provided in laterally spaced relation and connected by a handle extending there-between to enable simultaneous pivotal movement of the collapsible toggle linkages between the extended position raising the collector panel and collapsed position lowering the deflector panel.

Abstract: ABSTRACT IMPROVED OSTOMY DEVICE First and second annular interengaging parts releasably connect the pouch and adhesive-backed label. A member is provided for mounting one of the parts to the label, at a normal position proximate the surface of the label. The member includes a ring-shaped section, spaced from the part, which is adapted to be affixed to the surface of the label, and an expandable section, preferably including one or more accordion-like folds, inter-posed between the ring-shaped section and the part, to permit the part to be displaced relative to its normal position. The member will return to its normal position unless a detachable element is inserted beneath the member to retain the part in the displaced position. The other interengaging part may be provided with a flange-like portion situated to cover the expandable section, when the parts interengage, to protect the expandable sec-tion from waste material. Auxiliary interengaging parts may be provided to prevent accidental detach-ment and aid in supporting the pouch.

Abstract: ABSTRACT OF THE DISCLOSURE       A self-supporting reticulate of titanium hydride (TiH2) is formed by slurry-coating an open cell organic synthetic resinous material, or other pore-former, and eliminating the carbon-containing components of binder and/or solvent, viscosity modifiers, thickening agents, and the like at a temperature below about 400°C.  In an analogous manner, an inorganic refractory material open cell substrate or other pore-former substrate may be slurry-coated and converted to TiH2 reticulate in which the substrate is coated with TiH2 to yield a supported TiH2 reticulate.  Either the self-supporting TiH2 retic-al, may be sintered to yield an essentially pure Ti (metal) reticulate which is essentially free of titanium carbide.  Ti reticulates so formed are coated with Pt group metal oxides and used as anodes in chloralkali 20 cells.

Abstract: ABSTRACT OF THE DISCLOSURE In a method of manufacturing pure green light emitting diodes, after an n-type GaP epitaxial layer with thickness larger than or equal to a value for which the density of dislocation on the surface becomes less than or equal to 1 x 104 cm-2 is grown on an n-type GaP substrate, a p-type GaP epitaxial layer is grown on the above n-type epitaxial layer. Even with the use of a GaP substrate with normal dislocation density, the den-sity of dislocation in the neighborhood of the p-n junc-tion becomes low and therefore GaP green light emitting diodes with high intensity of light emission is obtained.

Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to a process for the recovery of one or more of the metals gold, silver, copper, zinc, vanadium, germanium and cobalt from pyrite concentrate.  The first step of the process comprises mixing pyrite concentrate with cyanide solvent so that the metals dissolve in the solvent.  The solvent and pyrite slurry is then dewatered to yield pyrite free of the metals and a cyanide solvent containing the metals.  The pyrite is separated from the cyanide solvent.  A first stream of the cyanide solvent is recycled to the first step and a second stream of the cyanide solvent is passed through activated charcoal.  The gold and some of the silver present in the solvent are adsorbed on the charcoal leaving the solvent barren in gold.  At least one of the metals remaining in the solvent is extracted by means of ion exchange, leaving solvent and an eluate of cyanide waste.  The cyanide waste is neutralized or destroyed and the solvent is recycled to the first step.  The continuous nature of the process minimizes the quantity of water required and the pyrite is almost completely separated into its useful components, with minimal waste.

Abstract: SOFT-STARTING PHASE-CONTROL CIRCUIT        FOR LOW VOLTAGE LOAD            Abstract of the Disclosure A soft-starting phase-control circuit for controlling both the cold in-rush and normal operating flows of current through a load from an A.C. source.  The load may be resistive, may have a non-zero resistance temperature coefficient and may require a load voltage thereacross lower than the voltage provided by the A.C. source connected to the load and the control circuit.  The control circuit  utilizes at least one power switching device for selectively enabling and disabling the connection between source and load responsive to turn-on and turn-off states of a control signal provided at the output of a gate subcircuit.  The gate subcircuit provides a turn-on state at a time, after each zero crossing, variably responsive to either a sensed load parameter when the load is in the normal operating condition, or to a selected starting sequence each time the load is initially energized (either intentionally or responsive to recovery from a detected fault condition) to limit in-rush current to a relatively low multiple of the normal operating current.  The start-up sequence of load turn-on states is responsive to gate enabling signals provided by comparison of a reference level with the instantaneous magnitude of a ramped signal, itself terminated and restarted at each line zero crossing.  Only if a phase-locked loop has been synchronized to the source line voltage zero crossings can the gate means be driven to the turn-on state.  The exact time when the ramp signal reaches the reference level is controlled by integration of the sum of the outputs of selected ones of a plurality of current sources.
