Abstract: A sundial-like timepiece comprising a conventional clock mechanism including a surface having a plurality of time interval markings inscribed thereon. A light source is attached to the clock mechanism and is disposed a spaced distance from the surface. The light source is moved relative to the surface by the clock mechanism on either a twelve or twenty-four hour cycle. A gnomon is disposed in such a position relative to the surface that the light source causes a shadow of the gnomon to be cast onto the surface. As the light source moves relative to the surface, the shadow moves across the time interval markings, and time can be read off the timepiece by observing the position of the shadow relative to these markings. If the light source is not functional, the time cannot be read off the timepiece.

The cantilevered members has a base end having a radial extent for stably supporting the corkscrew in an upright condition. The corkscrew is also provided with a cutter for cutting a foil wrapper which covers the mouth of the bottle.

Abstract: A process is disclosed for separating and recovering nickel and copper values from a nickel-copper matte which may contain iron and arsenic. Finely divided nickel-copper matte is leached in aqueous sulphuric acid solution under oxidizing conditions at atmospheric pressure and at a minimum temperature of about 80.degree. C. to selectively leach nickel from the matte to produce a nickel sulphate solution having a final pH in the range of about 4.0 to 6.5, preferably about 6.5, and to produce a copper-rich sulphide residue. The copper-rich sulphide residue is separated from the nickel sulphate solution and leached in a closed reaction vessel at a minimum temperature of about 120.degree. C. under a non-oxidizing atmosphere in a sulphuric acid solution containing an effective amount of copper and sulphuric acid to provide a terminal concentration of at least about 2 g/L Cu.sup.

Abstract: A refuse collecting vehicle with a two-tier collection compartment. Recyclable material is placed in the upper portion of the collection compartment and conventional rubbish is collected in the lower portion of the collection compartment. The receptacle for depositing the recyclable material preferably is located between the cab and the collection compartment. The roof closure device for a roof opening at the top of the collection compartment is operatively connected to the lifting arms of the receptacle whereby the roof is opened while the receptacle is lifted to its uppermost discharge position and closed as the receptacle is lowered to its lowermost refuse-receiving position.

Abstract: There is disclosed an affordable method and system of fully automating the instruction of a plurality of students which incorporates the use of a single CPU in conjunction with student questioning, responding and information feedback devices and which no longer relies upon the ability, mindset or even presence of a classroom teacher. The method further includes a fully-automated directly-integrated marks, records, reports and lesson management system.

Abstract: A sealing device for sealing the surface of contents of a container comprises a disc-like member having a central portion and a flexible perimeter and having a centrally located upstanding hollow handle having a purge valve at the upper end thereof. The purge valve has a closed position for preventing egress of air upwardly through said hollow handle and an open position to permit free passage of air therethrough. The disc-like member is contoured to correspond with the shape of the interior plan of the container.

The bottle is integrally molded from an olefin material. The face has a pump integrally molded therein. The pump comprises at least one endless ridge defining a valley. The valley has a wall thickness of about 40% of the wall thickness of the face.

Abstract: A modular galvanic current control resistor assembly for application to a metallic sheathed heating element of a domestic water heating tank to prevent heating element corrosion includes a circular metallic disc adapted to fit over the sheath ends of a U-shaped immersion heating element protruding in electrically insulated relationship through a metallic screw plug or the like mounting means used to affix the heating element to the tank, an electrically insulating gasket coextensive with the disc and a galvanic current control resistor having a pair of leads. The sheath ends of the heating element extend through the gasket and disc with portions of the disc around each sheath end crimped, compressed or friction fitted into electrical contact therewith.

Abstract: A size reduction machine for use in process industries to continuously and precisely reduce the size of particles, while controlling fines, comprises an impeller mounted on a rotatable shaft, a drive operably connected to the shaft for effecting rotation of the shaft. The shaft and impeller are vertically mounted within a vertically extending channel having an input and an output. A screen has a tapered apertured wall formed in a frusto-conical shape. The screen is rigidly mounted within the channel so that any particles passing from the input to the output pass through the screen. The impeller is shaped and mounted so that a gap between an edge of the impeller and an interior of the screen remains substantially constant as the impeller rotates relative to the screen. The improvement comprises the drive being operably connected to the shaft at a point under where the impeller is mounted onto the shaft.

Abstract: A palletized merchandising system comprises a pallet, a plurality of like containers stacked in layers on the pallet and a divider sheet interposed between the layers of like containers.
