Abstract: A charging circuit for charging a low voltage battery from an AC supply, said circuit comprising a full wave bridge rectifier, each leg of the bridge including a rectifying element, and means for providing a visual indication of normal operation of said charging circuit, wherein one of said rectifying elements is a light emitting diode to serve as said means for providing a visual indication.

Abstract: Ink compositions for use in capillary type writing instruments containing quaternary ammonium of the formula:RCH.sub.2 N(CH.sub.3).sub.3.sup.+ X.sup.-whereinR is --CH.sub.2 OH or --COOH, andX is --OH, --Cl, --Br, or --I.These ink compositions, when used in capillary type writing instruments, allow rejuvenation of writing points which have dried out from exposure to the atmosphere.

Abstract: Electronic game apparatus is provided which is controlled by a person jogging in place to establish a simulated race between a jogger and a simulated competitive runner on the face of a display. The simulated figures give an indication of accumulated input pulses between the jogger and the set rate of the electronic controls.

Abstract: A shaving unit comprising a frame, a blade member supported by the frame, first and second skin engaging elements supported by the frame and disposed respectively, in use of the unit, forwardly and rearwardly of the blade member, the first and second skin engaging elements being mounted in the frame in a manner permitting their resilient displacement relative to the frame and the blade member.

Abstract: An apparatus for measuring the incremental grooming force experienced by a hair tress during combing, and supplying an instantaneous readout of that force. The apparatus includes a comb or brush with strain gages attached to it which change resistance when mechanically deformed. The change in resistance is electrically measured to provide an indication of incremental grooming force. A continuous monitor is connected to the resulting electrical signal to provide an instantaneous indication of incremental grooming force. A method for using the apparatus to reduce the creation of split ends during hair grooming is also provided.

Abstract: A vibratory electromagnetic motor includes a stator unit, a first rotatable armature and a second rotatable armature. The armatures and the stator unit are arranged to reduce motor noise and vibrations when the armatures synchronously rotate in opposite directions in response to a magnetic force. A resilient coupling member is connected between the armatures for combining drive power generated by the first rotating armature with drive power generated by the second rotating armature.

Abstract: A product display card is described, which is particularly adapted to hold one or more elongate articles in organized close-packed array. The card is preferably formed from a one-piece paperboard blank, and includes a front panel with cutouts for opposite end portions of the articles to extend therethrough, and a pair of rear panels joined to the front panel at opposite edges thereof adjacent the end portions of the articles. The rear panels have cutouts generally aligned with the front panel cutouts, but dimensioned to retain the end portions of the articles at the front side of the card, while intermediate portions of the articles are retained at the rear side of the card. A feature of the product display card is that at least one end of an article to be displayed thereon and the front panel cutout corresponding to that end extends substantially to an edge of the finished card.

Abstract: A chewable tooth cleaning device comprising from 2.45 to 9.0 cm.sup.3 of substantially closed-cell compressible polymeric foam having a substantially skin-free surface adapted to scrub exposed tooth surfaces. In particular, the polymeric foam has about 12 to 50 cells per linear centimeter, a water absorptivity of less than 1.0 mg/cm.sup.3 after being submerged in water for 24 hours, a tensile strength of at least 3.4.times.10.sup.5 Pa, a compressive strength of at least 5.5.times.10.sup.4 Pa at 10% deflection, and at least 8.3.times.10.sup.4 Pa at 25% deflection, a tear strength of at least 1.38.times.10.sup.5 Pa, and is sufficiently resilient to return to at least 90% of its uncompressed height almost immediately after being compressed to 10% of its uncompressed height.

Abstract: Skin darkening compositions are made by dissolving cuprous chloride and either benzyl alcohol or 2,3-dihydroxybenzoic acid in an aqueous dermatologic base.

Abstract: A hair clipper, particularly for incorporation in a battery powered electric dry shaver, comprising first and second mutually slidingly reciprocable and inherently slightly resilient toothed cutters resiliently urged to assume a similar curvature to one another along the direction of reciprocation to tend to render uniform the pressure distribution therebetween.

Abstract: A roller-type cosmetic applicator is described featuring a cap of T-configuration adapted to fit on the outlet of a product container. The head portion of the cap has an integral cylindrical bearing element through which extends an axle having two rollers affixed at opposite ends. The axle has a reduced central portion defining a chamber between the axle and the bearing element. The chamber is in communication with the container, and, through two small openings, with the uppermost portion of the cap, where the product is delivered for distribution by the rollers. In one embodiment the reduced portion of the axle is provided with vanes comprising an impeller, which when rotated with the rollers and axle, assist dispensing of the product.

Abstract: A manually operated electrical switch includes a first conductor and a second conductor. The second conductor is telescopically coupled to an electrical contact arranged to be spring biased against an opposing surface. The second conductor is attached to an electrical insulator and assembled in a housing so as to be pivotally movable over an arcuate path between a first position in which the first conductor is in electrical contact with the second conductor and a second position in which the first conductor is electrically insulated from the second conductor.

Abstract: A process for producing long-lasting corrosion resistant carbon steel razor blades and the products made thereby. The process comprises first coating the cutting edges of the blades with chromium; and then immersing the blades in an electroless coating bath to provide a coating of a nickel-phosphorous, nickel- copper- phosphorous, cobalt-phosphorous or cobalt-nickel-phosphorous coating material on at least the bodies of the blades, the chromium coating preventing beading up of the coating material on the cutting edges of the blades to an extent that would require resharpening of the cutting edges. The blades may thereafter be overcoated with a carboxy-substituted silicone oil composition preferably comprising therein a long chain aliphatic acid, alcohol, amide and mixtures thereof.
