Abstract: An electronic water treating device comprising a brass body from which projects a graphite anode and to which is secured a stainless steel canister which functions as a cathode. The device includes an electronic power head connected to an external power supply. A 115 volt AC house current is transformed into two 6.3 volt circuits. The first anode powered circuit receives 6.3 volts which is rectified through a diode bridge and powers the anode through a biased resistance. The second 6.3 volt circuit is rectified through a diode and passes through a condenser and resistance through a transistor and resister to the anode. This latter circuit is a voltage measuring circuit interconnected through a relay to a warning light which is energized and lighted if substantial variation in the current being transmitted occurs. This usually arises when an accumulation of sludge-like calcium carbonate, calcium sulphate and magnesium collects in the canister.

Abstract: A drawing tool organizer comprising a plurality of units adapted to hold varied drawing tools, and connectors for releasably securing said plurality of units one to the other.

Abstract: A battery charger circuit having a temperature-dependent constant voltage region, a constant current region, and a power dissipation limiting current "foldback" region.

Abstract: A template guide for use with a parallel motion protractor or drafting machine having a substantially flat elongated base member with a longitudinal ridge extending substantially parallel to the edges of the base member and projecting normal to one surface of the base member, the ridge dividing said base member into first and second portions, the first portion being of a size efficient to cradle a drafting template and allow a drafting template to be moved longitudinally along the ridge parallel to a drafting arm of a parallel motion protractor, and the second portion being of a size efficient to cradle the drafting arm of a parallel motion protractor such that the ridge extends parallel to the edge of the drafting arm, and means for releasably securing the base member to the drafting arm such that the ridge is maintained parallel to the edge of the drafting arm.

Abstract: A solar powered lighting system including a light emitting unit electrically connected to a rechargeable power storage unit, a solar powered recharger connected to that power storage unit, means to prevent discharge of that power storage unit through the solar powered recharger, means to prevent overcharging of the power storage unit, means to prevent discharging the power storage unit below a predetermined level and means to automatically connect the disconnect the light emitting unit from the power storage unit wherein the voltage output of the solar powered recharger and the power storage unit is matched to the voltage required by the light emitting unit.

Abstract: A current limiting circuit for a switching regulator comprising a current sensing means operably connected to the positive terminal of a source of unregulated power and switching means operably connecting the positive terminal of said power source to the shut down input signal position of the switching regulator. When said current sensing means detects current in the positive terminal exceeding a predetermined value, the circuit of the present invention causes the switching regulator to adjust downward its duty cycle thereby preventing damage to the switching regulator due to current overload.

Abstract: A solar recharged power supply circuit for a lighting system which circuit includes a rechargeable power source, a solar powered recharger connected to that rechargeable power source and which circuit prevents discharge of that rechargeable power source through the solar powered recharger during times when the recharger is inactive; prevents overcharging of that power source; prevents discharging that power source below a predetermined level; and automatically connects and disconnects the lighting system to and from the rechargeable power source.

Abstract: A container closure lid and container dispensing top including a container dispensing top and a closure lid pivotally mounted on the container top and movable between an open position and a closed sealing position. The container lid further includes elongated serations disposed in an opposing relationship such that upon closure the serations will mate and form a multiple lock. The container lid is pivotally mounted to the container top through pivot points below the closure surface of the container top and the container top closure surface is generally inclined downwardly toward the pivot points.

Abstract: Method and apparatus for flame treating seed, particularly seed having awn. The method and apparatus entails passing awned seed through successive flame treating stages with cooling periods between successive flame treatments.
