  • Patent number: 6065365
    Abstract: A control lever assembly for generating an electrical signal representative of the position of a linearly-moveable control lever which extends through an elongated passage in a console cover includes a control lever guide rotatably mounted to a bracket beneath the console cover. An arm projecting above the console cover is provided for moving the guide between rotational positions. The guide has an opening with slots of predetermined length associated with the rotational positions which define ranges of linear movement of the control lever. The movement of the control lever causes a sensing circuit to generate the electrical signal representative of the position of the control lever. The assembly also includes a switch actuated by a cam on an end of the guide depending upon the rotational position of the guide. The assembly also includes detent mechanisms for releasably retaining the control lever and the guide in various detent positions.

  • Patent number: 5206365
    Abstract: A series of psychotropic heterobicycloalkylpiperazine derivatives having the structure ##STR1## wherein V is a 3- or 4-membered unsaturated chain, containing all carbon atoms when 4-membered, or when a 3-membered chain, V contains an oxygen or sulfur atom as one of the members; R is H or C.sub.1-4 alkyl; W is CH, N, CH.sub.2, or a chemical bond; X is CH, N, SO.sub.2, or CO, with the proviso that both W and X cannot simultaneously be N; and Z is a heteroaromatic ring system. These compounds are useful antipsychotic and/or anxiolytic agents.
