Abstract: A valve is interposed between spaced valve seats of a conduit having end portions communicating with the ends of an internal combustion engine valve cover. The conduit has a vent port located between the valve seats. The valve, which is responsible to inertia and centrifugal forces, is disposed in the conduit between the valve seats for shutting off one or the other ends of said conduit to prevent the loss of upper engine lubricants from the valve cover during rapid acceleration, deceleration or sharp cornering of a vehicle driven by the engine.

Abstract: A rotary driven conical drum into a large end of which sludge and a flocculating polymer are discharged, constitutes a contact chamber, and is equipped with baffles and weirs. The polymer is supplied to a large end of the drum and mixing is accomplished in the large end of the drum where the surface area of the drum is moving most rapidly. Thereafter the mixing action is slowed down by travel of the mixture to the smaller end of the drum, where the surface area of the drum is moving more slowly, to build up the flocs. The sludge/polymer mixture produced in the contact drum is then discharged through a conduit into the large end of a rotary driven conical concentrator drum. A maximum amount of the free water in the mixture is released from the concentrator drum through its screen side wall at the large end of said drum. The flocs remaining in the screen drum, after initial release of the water therefrom, are protected by their travel to the smaller end of the drum where the surface movement is slower.

Abstract: A carrier in which CB radios of different sizes can be detachably secured for convenience in carrying. The power pack, consisting of a plurality of dry cell batteries connected together in series and a battery holder forming a part of the carrier, provides a portable power source for the radio. The carrier is constructed to be supported by a part of the body of the user and is provided with means for detachably supporting an aerial connected to the radio.

Abstract: An inflated casket which may remain deflated for storage prior to use and for transportation prior to storage. The casket body is provided with one or a plurality of chambers into which a fluid substance is injected for distending the chambers to cause the casket body to assume an erect position for use. The fluid substance while usually in the form of a gas, such as air, may constitute a substance which will subsequently solidify to produce a substantially rigid casket body.

Abstract: A plate of porous or open work construction detachably mounted in a paint receptacle and buoyantly supported at a predetermined depth beneath the surface of the paint to be engaged by the tips of the bristles of a paint brush, to prevent the paint brush from being dipped too deep into the paint and to indicate when the paint brush has been dipped to a desired depth.

Abstract: A sneaker or canvas shoe having an insole comprising a soft pad which is encased in a sealed film envelope to prevent the pad from absorbing moisture, odors and contamination. The envelope includes a chamber disposed beyond an end of the pad into which air can be forced, from the area of the envelope surrounding the pad, when pressure is applied to the insole by the weight of the wearer of the shoe. A part of the air chamber is heat sealed to the toe portion of the shoe, during the manufacture of the shoe, to retain the insole correctly positioned within the shoe.

Abstract: A mechanical support for a short flexible hose section including a rigid L-shaped bracket having an upright leg to an upper end of which is rigidly secured a short rigid conduit section, which is disposed crosswise of said leg and to an inner end of which is secured one end of a flexible hose. The other lower horizontal leg of said bracket, which extends under said flexible hose, terminates in an upright bearing sleeve which rotatively receives a pivot pin. One end of a rigid arm, constituting the other section of said mechanical support, has one end secured to the upper end of said pivot pin for swingably supporting the arm relative to said bracket. A second short conduit section is rigidly secured to the other upturned end of said arm. The other end of said flexible hose is secured to the inner end of said last mentioned rigid conduit section.

Abstract: A one piece holder preferably formed of a molded plastic having a first clamp for releasably engaging an edge portion of a safety helmet to detachably mount the holder thereon, and a second clamp projecting outwardly from one jaw of said first clamp for detachably receiving and holding a long slender object such as a pencil or pen.

Abstract: A frame which is detachably secured to a wig form supports a fabric hood or cover of a lightweight flexible material over a wig, which is applied to the form, to protect the wig from dust. The hood or cover is supported by the frame so as not to mash or otherwise disturb the wig while positioned thereover. A handle which forms a part of the frame and extends over the top of the form, above the cover, is utilized for lifting the form with the wig applied thereto.

Abstract: A self cleaning air cleaner for a tractor engine which is capable of functioning either alone for cleaning air being supplied by suction to a carburetor of a gasoline engine or to the turbocharger of a diesel engine, or which can function as a pre-cleaner for air being supplied to a conventional air filter.

Abstract: An apparatus utilizing a functioning telephone system for teaching children of elementary school age number discrimination, mathematic concepts, letter discrimination and coding, spelling, improved reading comprehension, and a variety of other verbal concepts. The apparatus is especially adapted for use in schools. It is operated solely by students and includes a telephone switchboard which is electrically connected to a plurality of modified touch-tone telephones. While the telephone users may talk with one another when their telephones are connected through the switchboard, communication between the telephone users and switchboard operator is entirely by visually presented instructions.

Abstract: A completely integrated and automated apparatus by which liquid sewage sludge from any sewage or waste treatment plant may be processed into a completely dry, pelletized and sterilized product of an organic nature containing nutrients valuable for the support of plant life. The apparatus involves one completely integrated and automated unit together with a control center by means of which electric circuits program each component of the apparatus to automatically regulate the operation of each component, so that no labor or other manpower is required in the operation, except for observation, lubrication, maintenance and repair of the various motors and machineries involved.

Abstract: An apparatus including a mixing tank connected to a source of water supply under pressure, by which the tank can be partially filled with water to be mixed with a poison in powder form, which is admitted to the tank through an access opening, normally closed by a transparent cover forming a window through which the mixing operation can be observed. Spray heads connected to the water supply source spray water across the top of the tank to settle dust from the poison powder, and a suction means communicating with the top part of the tank extracts poisonous fumes, caused by the powder, from the tank and discharges such fumes into a purifying unit from which purified air only is discharged. A pump connected to an outlet of the tank discharges the mixture under pressure to spray heads or other discharge means after first recirculating the mixture to complete the mixing operation.

Abstract: A tensiometer having a vacuum gauge which is connected to a sensing unit including a ceramic cup, which is located remote from said gauge, by a conductor in the form of a capillary tube. A second capillary bleeder tube communicates with and leads from the ceramic cup and has a second end which is located below the level of the other end of the conducting tube, so that when said second end of the bleeder tube is exposed, the escape of air therefrom can be visually determined, during purging of the device, so that after all air has been removed from the tubes, the tensiometer can be sealed.

Abstract: A soap bar composed of a hollow shell of bar soap material defining a cavity filled by a core composed of small remaining pieces of soap bars and a congealed mass of a soap solution.
