Abstract: A wheel camber adjustment linkage of the disclosure is utilized with a vehicle independent suspension system to sense and correct an improper wheel camber angle condition. The linkage includes first and second portions associated with a suspension control arm on which an adjustable joint is mounted. The first linkage portion senses the angular relationship between the control arm and a wheel supporting member mounted on the control arm by the adjustable joint. The second linkage portion senses the angular relationship between the control arm and the sprung mass of the vehicle. The angular relationships sensed by the two linkage portions are compared so as to determine whether adjustment of the joint is necessary to correct the wheel camber angle. If correction is required, the angular linkage movement during suspension jounce provides the impetus for the adjustment. Each linkage portion preferably includes a push-pull link and a lever pivoted to each other.

Abstract: A method of treating semen from male fowl to increase the production of fertile eggs by female fowl inseminated with the treated semen by exposing the semen to a magnetic field of predetermined intensity and for a predetermined period of time. The semen so treated increases the number of fertile eggs produced by the female fowl inseminated with the treated semen. The invention also includes a method for treating fertile eggs to increase the hatch rate and the rate of growth of fowl hatched from the treated eggs. The eggs are treated by placing the eggs in a magnetic field of predetermined intensity to expose the eggs to the magnetic field and then removing the eggs from the field after a predetermined period of time. Preferably, the magnetic treatment of the eggs is done prior to incubation.

Abstract: A hanger for pictures or the like is disclosed as having an upper suspension point and a pair of lower wire receiving hooks for receiving a laterally extending wire on a picture to be hung. The hanger includes an aperture at the upper suspension point for receiving a nail or the like which suspends the hanger on a wall. The wire receiving hooks are spaced laterally on opposite sides of the aperture the same lateral distance. Pivoting of the hanger during its suspension levels the hooks with each other. The lateral spacing of the hooks supports the picture wire so as to prevent pivoting of the picture about the hanger. The hanger preferably has an inverted Y shape whose upper leg defines the suspension aperture and whose lower two legs define the wire receiving hooks. The hanger is made from a metallic body and is stamped to form the hooks and reinforcing ribs in each leg as well as projections that engage the wall to prevent pivoting of the hanger about its suspension point.

Abstract: A method and machine for splining a power transmission member by rolling are disclosed as well as the resultant splined member. An externally toothed pinion-type mandrel of the machine is rotatably mounted between a pair of elongated dies. An unsplined member is supported by the mandrel so that sliding movement of the elongated dies from an end-to-end relationship to an overlapping relationship meshes teeth on the dies and the teeth on the mandrel with a thin-walled annular sleeve portion of the member therebetween. The meshing of the die and mandrel teeth deforms the sleeve portion of the member radially to form the splines and also rotates the mandrel to complete the spline forming operation about the total circumference of the member. The mandrel may be removably mounted in a manner that permits a pair of the members to be simultaneously splined by a single stroke of the elongated dies.

A pair of snow plow ramp sections are formed on the body on opposite sides of the fore and aft axis, each of the ramp sections including a pair of snow plow ramps extending in opposite directions from the transverse axis. Each of the snow plow ramps has an enlarged end adjacent the transverse axis and decreases in cross-section to a tip portion at the distal end thereof spaced from the transverse axis.

Abstract: In accordance with the invention, hollow pellets having outer surfaces of one material and inner surfaces of another material are manufactured by dropping drops of liquid into a bed of powder containing the material of which it is desired to make the outer surface portions of the hollow pellets and preferably also a binder, the liquid containing the material of which it is desired to make the inner surface portions of the hollow pellets. When the drops of liquid fall into the powder, the powder immediately forms a spherical shell around each drop so as to form the hollow pellets upon vaporization of the liquid. It is preferred that the powder additionally contain some sodium bicarbonate or the like and that the liquid be an aqueous acid solution such that, upon initial formation of the spherical shell of powder, the acid reacts with the sodium bicarbonate to generate carbon dioxide which causes the spherical shell to expand while yet additional powder coalesces onto the shell.

Abstract: A novelty item of the disclosure includes a base, a first biological symbol of one sex mounted on the base projecting therefrom, and at least one biological symbol of the other sex that may be thrown over and caught by the base mounted symbol. The base mounted symbol is preferably of the male gender and the thrown symbol is of the female gender. Each thrown female symbol has its sex indicating cross configuration projecting from its circular portion for a distance approximately equal to the diameter of the circular portion so that the symbol may be thrown in a ring-like manner while still maintaining its shape generally like that of a biological symbol. The male symbol also has its sex indicating arrow configuration projecting from its circular portion for a distance equal to the diameter of the circular portion so as to have a shape like the female symbols. The male symbol is also preferably of the same size as the female symbols to give the novelty item an aesthetically appealing appearance.
