Abstract: A portable security grill apparatus which may be installed in window openings of buildings includes two rectangular grill sections longitudinally telescopically fastened to one another. Opposite longitudinal ends of the two grill sections have beams disposed perpendicularly to the axis of longitudinal telescoping movability of the two grill sections, the beams having flat outer surfaces adapted to abut a window edge at one end of the grill apparatus, and a window frame edge, at the other end of the apparatus. At least one toggle clamp connected between telescopically joined members of the two grill sections is capable of exerting a large outward extension force when in a closed, clamped position, thereby exerting compressive forces on the window and window frame sufficient to prevent the grill apparatus from being removed from the window opening.

Abstract: There is disclosed a clip which is molded of plastic and which has a design particularly adapted to retain fabrics on the crossbar of a conventional clothes hanger. The clip has a C-shaped body having opposite, coincident legs dependent from a central bight section, an integrally formed prong dependent from the bight section and an upright base leg projecting out of the plane of the clip body with a first reverse bend adjacent the base leg and a return prong section which is inclined towards the plane of the clip, and a second reverse bend in the prong to provide an upwardly curled tip which also projects out of the plane of the clip. The height of the base of the prong and the first reverse bend are sized to provide sufficient clearance from the body of the clip to permit snap-over retention of the clip on the cross bar of a hanger. Preferably, the body legs and the prong have textured or roughened opposing surfaces to enhance their gripping properties.

The braces 18 have at their bottom ends stake holders 16 and 17 which receive stakes 23 that are driven into the ground. An anchor 24 holds the main support post 31 in position.

Abstract: There is disclosed a method for treatment of an oil slick resulting from an oil spill on a body of water. The oil slick is treated with a mixture of a granular elastomeric gum comprising a block copolymer of ethylene/butylene and styrene and an oleochemical synthetic wax, the latter being used in amounts of from 1 to 33 weight percent of the mixture. The adsorbent mixture has a low density, typically from 14 to about 15 pounds per cubic foot and will absorb oil and form a dry solid which has a non-tacky and non-oily surface. The adsorbent mixture is broadcast on the surface of an oil slick in proportions from about 0.2 to about 1 part per weight part of oil. The wave action on the body of water is generally sufficiently turbulent to admix the absorbent with the oil of the oil slick, resulting in the formation of floating solids which are dry to the touch and which have a non-oily, non-tacky surface. These solids can be readily recovered from the water or from a shoreline after they have washed ashore.

Abstract: A system for marking hidden utilities such as buried gas lines, valves and the like includes a marker having highly visible indicia indicating the type of utility on one face and which is bonded to a permanent object adjacent the location of the utility. The highly visible indicia is light reflective or fluorescent or both. The indicia are also recessed in the face of the marker for protection. The marker is affixed to a permanent object such as a curb face or surveying monument in the general location of the utility. The indicia on the marker represent the type of utility and the marker may also contain indicia representing the distance and direction from the marker to the utility location. The system can be provided in kit form which includes, in addition to the marker, a bonding material for affixing the marker to a permanent object and a marker for inscribing information relating to distance and direction on the marker.

Abstract: There is disclosed a tool for the removal of locking collars of the frangible fasteners used in the aerospace industry, particularly for removal of fasteners installed in close quarters such in a deep channel where conventional tools cannot grip the collar. The tool has a collet-type chuck to grasp the collar of the fastener and has a lead screw to lock the collet chuck about the collar and permit removal of the collar. For this purpose, the collet chuck has a cylindrical neck which is received within a sleeve. The lead screw is received in the opposite end of the collet sleeve and is threadably engaged in the internally threaded bore of the collet chuck member, preferably with left hand threads, and has a head with wrenching flats. The lead screw has a central axial through bore which receives a key member which is used to immobilize the stud or bolt of the fastener system. A disk member is slidably received within the collet sleeve to eject removed collars from the collet chuck member.

Abstract: There is disclosed a spray head for an airless spray gun. The spray head has a tubular housing for removable attachment to the discharge end of an otherwise conventional airless spray gun, adjacent the valve member of the spray gun. The housing is counterbored to form an inner annular shoulder and contains a removable plug that is slidably received within the housing. The annular shoulder is stop for the plug which is retained in the housing at the preselected location by a retainer member that is removably threaded into the discharge end of the housing. The plug has, on its upstream end, a valve seat to engage the valve member of the spray gun and, on its downstream end, a discharge orifice formed by divergent angular bores which intersect a through bore of the plug.

Abstract: There is disclosed a method and an apparatus for treatment of water in an electrolytic cell having stacked plates of magnesium and copper in alternating array, separated by thin metal, brass washers. The stacked plates are disposed transversely across a cylindrical treatment chamber, preferably with four stacks aligned on equally angular spacings within the chamber. The water to be treated is introduced into the chamber tangentially to the inner wall thereof and is directed over the stacked plates. The tangential introduction of water into the treatment chamber generates a vortex flow of the water across the electrolytic cells which accelerates clarification of the water by forced separation of the precipitates which are collected in the bottom of the separation chamber and periodically removed. The clarified water is removed from the treatment chamber and passed through subsequent processing.

Abstract: There is disclosed a method for the removal of impurities, particularly organic impurities from granular solids, having its greatest immediate application for the regeneration of spent adsorbents which are used to purify waste water. The spent activated carbon is immersed in an aqueous bath which preferably contains a surface active agent, and water is circulated over the activated carbon while ultrasonic vibration is applied to the aqueous bath at a frequency from about 1 to about 100 kHz to desorb the organic adsorbate from the activated carbon. The desorbed organic compounds are washed from the activated carbon by the circulating water stream and are decomposed by introducing ozone into the water stream and, most preferably, while subjecting the water stream to ultraviolet radiation, thereby producing a wash water which can be safely discharged to the environment.
