摘要:
A unique interlock mechanism for two pushbuttons or other linearly operated devices, requiring no mechanical linkages or complex assemblies. The interlock mechanism essentially comprises an interlock member having first and second restraining portions disposed within a housing so that when one of the pushbuttons is operated, the interlock member rotates positioning itself under the second pushbutton, interfering with and making it impossible to be operated.

A game apparatus including a stand having a generally horizontal platform connected to a generally upright column. The platform has a plurality of distinct sides with point value indicia associated with each of these sides. A target object is placeable on the platform and is connected to the platform by tether means. A projectile is thrown at the target object from a remote distance with the object of knocking the target object from the platform over one of said sides. The points awarded the player participant throwing the projectile depends on which of the sides of the target is knocked over.
摘要:
A convertible switch operator for use as a pull momentary and as a push-pull momentary operation characterized by a tubular selector longitudinally movable in a housing and spring biased by a first spring for operation as a pull operator; and spring biased by two springs in an intermediate position as a push-pull operator.
摘要:
A switch structure characterized by a pushbutton-rotatable switch handle and a plurality of switch blocks mounted in tandem, the switch blocks comprising molded base and cover portions which provide an insulating barrier between the moving and stationary contact arms for increased current capabilities, and the switches having reciprocable switch operating plungers which are actuated either together or separately by longitudinal or rotary movement of the switch actuator.

An integrated avionics control and display arrangement is disclosed which combines symbol generation, display and mission processing, and multiplex bus control in a single processor configuration. The arrangement features "home" pages for primary parameter display with selectable additional pages available in conjunction with operator-operable keys disposed around the display. A wide variety of control signals compatible with the multiplex bus format are integrated directly with the bus, and a wide variety of non-compatible signals are integrated with the bus through remote terminal units which are arranged in a redundant configuration for system failure survivability and enhanced interconnect wiring economy.
摘要:
A detachable switch structure comprising an actuator, a contact block mounted on the actuator, and an adapter for mounting the contact block on the actuator; the block comprising a dielectric housing and enclosing separable contacts; the block being mounted on the actuator; the actuator comprising detachable interfitting means cooperative with corresponding means on the contact block housing which interfitting means includes elongated hook members on the adapter engageable with projections on the housing, the hook members including windows engageable with the projections, and the hook members including openings for insertion of a tool between the hook members and the projections for disengaging the same.

摘要:
The present invention is a method and apparatus to generate first and second strobe signals to receive data on an interface port of a processor operating in first and second modes at first and second voltage levels, respectively. The second voltage level is higher than the first voltage level. A selector provides first and second selected signals from a plurality of signals which corresponds to the first and second modes. The selector operates at the second voltage level. A signal generator is coupled to the selector to generate the first and second strobe signals from the first and second selected signals.
