Abstract: An assembly for effecting the lifting of a paper roll wherein the roll includes a hollow axial core, the assembly including a support designed to interlock with the core at one end thereof and a lifting sling engaging, at one end, the support and extending therefrom through the hollow core of the paper roll so that it will protrude from the other end of the core.

Abstract: The toy action figure includes a body having one leg mounted for rocking movement toward and away from its other leg. The figure also includes one arm mounted for swinging movement about a generally vertical axis provided by a ball member on said arm and a ball cup integral with the figure's body. A motion-converting mechanism is contained within the body which mechanism comprises an actuating lever which is rocked when said one leg is rocked. The actuating lever includes a triangularly configured cam at its upper end having an angled cam edge which engages against an edge on a panel. The panel is integral with a transmission lever that constitutes an inverted T-shaped member and which pivots abouts its lower T-shaped end when the cam edge acts against the panel edge so as to cause a generally vertical pin of the upper end of the transmission lever to force in an angular direction a lever arm integral with a ball member on the arm to be swung.

Abstract: The toy action figures includes upper and lower hollow torso portions. An actuating mechanism is contained in the upper torso and acts through a helical gear mechanism to rotate the lower torso portion and the legs attached thereto about a longitudinal axis when one of the figure's arms is swung from a diverging relation toward one side of the figure. A spring is used to return the actuating mechanism and the limbs associated therewith back to their normal or unactuated positions. Another spring releases or disconnects the lower torso portion from the actuating mechanism should the child attempt to twist the two torso portions relative to each other by using too much force.

Abstract: An impact responsive toy vehicle in which two separable halves each carrying surface engaging wheels are connected together to provide a vehicle supported on the surface engaging wheels. A torsion spring biases the joinable ends of the two halves to separate and each flip over. The parts are retained together by a connecting latch that is disengageable by a slidable lever that moves in reponse to a force on an extending front bumper. One half carries a rotatable lock including a lug that cooperates with an abutment on the lever to lock the trigger lever against sliding movement in response to impact on the bumper. Fail-safe combination of the two parts rendering the impact responsive feature totally inoperative is accomplished by assembling the parts together with the arm of the torsion spring received in a recess on the underside of the chassis of the other half.

Abstract: A double throw electrical switch construction having a housing carrying a movable actuator unit for moving a snap switch blade of the housing over center to snap a contact portion of the blade between a pair of spaced contact stops carried by the housing, the actuator unit comprising an actuator plunger and an actuator spring. The actuator spring is movable relative to the housing and has one of the opposed ends thereof operatively interconnected to the blade to move the blade as the spring is moved. The plunger has a lost motion arrangement for acting against an intermediate portion of the actuator spring to cause movement thereof as the actuator plunger is moved whereby the actuator spring can move relative to the actuator plunger through the lost motion arrangement thereof.

Abstract: An electrical switch construction having a housing carrying a pair of spaced contact stops and a snap switch blade having a contact portion for being snapped between the stops when the blade is moved over center by an actuator spring member that is movable relative to the housing by an actuator plunger. The actuator spring member has opposed ends respectively and operatively interconnected to the housing and to the blade and being under tension between the ends thereof so as to have a resultant spring force normally tending to move the actuator spring member toward the plunger and thereby the switch blade toward one of the contact stops. The actuator spring member comprises a one-piece substantially L-shaped leaf spring member separate from the blade and having two legs respectively defining the opposed ends thereof, one of the legs being pivotally mounted to the housing to operatively interconnect that one leg to the housing.

Abstract: An electrical switch construction having a fixed contact and a movable switch blade carrying a contact for cooperating with the fixed contact under the control of an actuator spring that sustains a contact force on the closed contacts until the actuator spring is snapped overcenter by a movable actuator member operatively associated with the actuator spring, the construction having a stop normally spaced from the actuator spring and adapted for only being engaged by the actuator spring and thereby limiting movement of the actuator spring caused by normal actuation movement of the actuator member when the actuator spring is snapped in one direction by the actuator member to close the contacts. The stop comprises a biasing means.

Abstract: Hydrocarbon soluble organo-magnesium complex of the formula(RR'Mg).sub.m .multidot. (R.sub.3 Al).sub.nwherein R is a primary, secondary or tertiary alkyl group having from 1 to 25 carbon atoms. R' is a primary alkyl group having 1 to 25 carbon atoms, or phenyl group, or mixture thereof, and m and n are numbers such that the ratio of m/n is about one or greater.These complexes are prepared by reacting magnesium metal with a primary alkyl halide or phenyl halide in the presence of a hydrocarbon solvent and adding thereto a metal organo-aluminate of the formula R.sub.4 AlM wherein R is as defined and M is sodium, potassium or lithium. The metal organo-aluminate compound functions as a solubilizing agent for organo-magnesium compounds which are normally only slightly soluble in hydrocarbon media. These complexes are characterized by very low halide content, lack of ether contamination, magnesium to aluminum ratios of between about 1:2 to about 20:1, and hydrocarbon solubility.
