Thereby, slide-slipping angles .alpha..sub.R, .alpha..sub.L and camber angles C.sub.NR, C.sub.NL of the right and left front wheels respectively, are determined so as to determine the compensating angle y, according to the equationy=a(.alpha..sub.R +.alpha..sub.L)+b(C.sub.NR -C.sub.NL)+c,wherein a,b,c represent constants determined by the type of vehicle involved.

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 with a contact force being sustained at the "trip point" of the switch construction by an actuator spring of the actuator unit being moved over center before the blade is moved over center by the snap movement of the actuator spring. The actuator unit includes an actuator plunger having lost motion means directly acting against the actuator spring whereby the actuator spring can move relative to the actuator plunger through the lost motion means thereof when the actuator plunger moves the actuator spring over center in either direction thereof.

Abstract: A method and apparatus for forming a seamless container having a sidewall and an integral end wall with opening means in the integral end wall is disclosed herein. The method contemplates forming at least one substantially closed area of reduced thickness in the end wall to produce a fracturable web that defines an opening means during the conversion of a flat disc to a finished container. In one form, the method contemplates initially forming a shallow cup and then forming the opening means in the end wall of the shallow cup before the cup is converted into a drawn and ironed container. In another form, the opening means is formed while the container end wall is being reformed into its final configuration and in a further version, the end opening means is formed in the end wall after completion of the drawing and ironing process. The finished container includes a reformed end wall that is integral with a circular sidewall of a container and has a fracturable web surrounding a protuberance.
